Patent No. RE22889E: Stationary Type Hop Picking Machine

patent-logo
Today in 1947, US Patent RE22889 E was issued, an invention of Florian F. Dauenhauer, for his “Stationary Type Hop Picking Machine.” There’s no Abstract, although in the description it includes this summary:

Hops are raised on a trellis sixteen to eighteen feet in height. When ripe, the vines are out about four feet from the ground, the strings supporting their upper ends to the wire or trellis overhead being either broken by pulling on the vines or cut. Hand picking of hops, owing to the conditions surrounding the growing of hops, the shortness of the season, scarcity of labor and the like, is very expensive and the best hand picking leaves a large percentage of foreign material in the hops and the necessary sacking, boxing and delay in getting hand picked hops to the dry house often results in the discoloring, bruising and flattening of the hops themselves and entails many objectionable incidents.

My invention is an improvement over Patents Nos. 1,054,119 and 1,054,551 covering an apparatus and method for picking hops. In the patents, the picker drums are arranged in two horizontal rows with the drums in the upper row being disposed vertically above the drums in the lower row. The passage between the two rows of drums in the patented devices is therefore restricted in depth between each pair of drums and is of greater depth between adjacent sets of drums. This results in a passage having varying depths and the vines will be unnecessarily compressed each time they are moved through the restricted portions of the passage. The breakage of parts of the vines takes place more readily because of this. Moreover, the arrangement of the drums in vertical pairs leads to another disadvantageous feature of the machine. The hops are picked only where the vertical pairs of drums occur and no picking takes place between adjacent pairs of drums. The picking operation is therefore not continuous throughout the length of the passage.

One of the objects of my invention is to provide a hop picker in which the picking of the hops is continuous throughout the length of the passage through which the vines are moved. A further object of my invention is to provide a passage of uniform depth throughout. A more complete picking of the hops results and there is less breakage of the vines since the vines are carried through a passage of uniform depth rather than through one where the depth varies between each pair of successive drums.

A further object of my invention is to provide a novel vine carrier made of endless cables and carrying vine grasper bars, the bars in turn having vine gripping jaws that are automatically closed on the vines at the feeding end of the machine and are automatically opened so as to free the vines at the exit end of the machine.

Patent No. 2440276A: Brewing Method Using Albedo In Wort

patent-logo
Today in 1948, US Patent 2440276 A was issued, an invention of Abraham Arnold Klein, for his “Brewing Method Using Albedo In Wort.” There’s no Abstract, although in the description it includes this summary:

According to the present invention albedo from fruit of the genus Citrus, particularly from grapefruit or citron, is used instead of, or in addition to, hops in the manufactured beer. I have found that the lupulin of hops has in many cases undesirable effects on the human organism. Furthermore hops deteriorate easily. Albedo from citrus fruit can be used instead of hops and the bitter flavour imparted by it to the wort is of a mild and agreeable character.

So this is essentially using grapefruit or other citrus almost 70 years before Ballast Point Grapefruit Sculpin. But not the whole fruit, or even the rind, the albedo is the white, fleshy inner later in between the thinner, top rind layer and the inside fruit. That spongy material is, according to this patent, used in place of or with hops in the brewing process. I wonder if anybody used this method to produce commercial beer?

Patent No. 20090098075A1: Hops-Based Deodorant

patent-logo
Today in 1963, US Patent 20090098075 A1 was issued, an invention of Chantal Bergeron, Stefan Gafner, and Jennifer L. Lafrance, for their “Hops-Based Deodorant.” Here’s the Abstract:

The present invention relates to deodorants and other body care products comprising a CO2 extract of the hops plant having bacteriocide/bacteriostat properties wherein the CO2 extract has a very low level of essential hops oils.

US20090098075A1-20090416-D00001

So some deodorants today do list hops as an ingredient, such as the Tom’s of Maine line, all of which list Hops extract [CO2] and caprylic/capric triglyceride as one of the ingredients.

Which on Tom’s website they have a separate page for each of the body care ingredients, including Hops extract [CO2] and caprylic/capric triglyceride:

What is it?

The hop plant is a perennial herb that grows in vines. Native to Europe, Western Asia, and North America, it is known for the speed and persistence of its growth. Most people are familiar with hops because of its role in beer-making, although it also featured in ancient kitchens and the medical recipes of herbalists. First widely used in beer by monks in 9th- and 10th-century Germany, the hop didn’t gain popularity because of its flavor. Instead, the “bitter principles” of hops exhibit antimicrobial behavior, making the ingredient an effective preservative and stabilizer. In 1516, Wilhelm IV, lord of Bayern, ordered that hops be one of the required ingredients in beer in his Reinheitsgebot (Purity Law). That law led to similar enactments in other countries and helped to standardize the use of hops in brewing. Hops’ distinctive bitterness has now become one of the familiar attributes of a typical beer. Only the female flowers, known as cones, are used in beer-making. For our deodorants, we use hop resins extracted from the cones.

What does it do?

Unpleasant odor is caused by skin bacteria when we sweat. The “bitter principles” that help hops to preserve beer also, it turns out, fight odor. Hops inhibits the growth of bacteria in our deodorant by causing leakage in the bacterial cell membrane, which impairs bacterial function and therefore prevents odor. We use hops in all but our Long-Lasting Roll-On Deodorants.

What are the alternatives?

Lichen (Usnea barbata) has been in our (and many other natural) deodorants since 1991, and it provided effective and natural odor protection. However, a minor percentage of the general population—often, those who tend to have fragrance allergies—may experience a skin reaction to lichen. Even though it’s a relatively uncommon reaction, we weren’t satisfied, and our scientists continued to search for ingredients with less irritancy potential. We also felt increasingly uncomfortable with the environmental drawbacks to using lichen. Studies have shown that the large-scale harvesting of lichen may not be sustainable given its long regeneration rates.

What are the risks?

Hops are believed to have sedative properties, but topical application in the amount found in our deodorant will not cause sleepiness. Tom’s of Maine recognizes that no two people are alike, and even with pure and natural ingredients, some individuals may develop an allergic reaction that is unique to them. As with any product, be sure to discontinue use if you experience discomfort or other indications that the product may not be appropriate for your individual body chemistry.

Patent No. 46973A: Improved Process For Obtaining A Condensed Extract Of Hops

patent-logo
Today in 1865, US Patent 46973 A was issued, an invention of Samuel R. Percy and Walter S. Wells, for his “Improved Process for Obtaining a Condensed Extract of Hops.” There’s no Abstract, although in the description it includes this summary:

Our invention consists in the preparation of a condensed extract of hops, which possesses all the valuable properties of the hops, which is computed to lose about thirty-three and one-third per cent of their strength the first year, and afterward to decline more rapidly. All these and other objections are entirely obviated by our invention.

A quantity of hops is placed in an air-tight vessel, and the air is then exhausted therefrom in any of the methods ordinarily used for that purpose. Warm or cold water is then introduced, which should be kept heated by the admission of steam, and the hops allowed to steep for two or three hours. The degree of heat is not essential. We prefer that it should approach nearly to the boiling-point of water in vacuo. A small quantity of alkali or alkaline salts should be added to the water, the amount, when so used, not to exceed one pound of alkali or its equivalent of alkaline salts to I every one hundred pounds of hops. When the hops, by these means, are sufficiently digested, a vacuum is formed in a chamber communicating with the vessel in which the hops have been steeped, so that when the cooks communicating between this vessel and this receiver are opened the water and condensed steam containing the virtues of the hops pass through into the receiver, a vacuum being maintained therein sufficient to draw all the liquid from the hops. Water and steam are again and again admitted into the steeping vessel, as before described, until the hops are entirely exhausted of their properties. The fluid thus holding said properties in suspension is strained through a suitable strainer adjusted within the connecting pipe while in transition from the steeping-vessel to the receiver. When a sufficient quantity of this fluid extract of the hops, effected as above stated, is accumulated in the receiver, a vacuum evaporating-pan is ready for its reception by covering or coating its inner surface with any oily or fatty substance cerine, paraffine, &c., to prevent the extract from adhering to the pan and burning. Avaouum is then formed in this pan and the fluid extract is drawn through a pipe or tube connecting with the receiver, as fast as needed, into this vacuum, evaporating, or condensing pan. At such time, during the process of evaporating and condensing such fluid, as the operator may deem proper, a quantity of molasses, saccharine matters, or the extracted liquor of grain, whether malted or not, is to be drawn into the vacuum condenser and mixed with the fluid therein contained, amounting in quantity to about three gallons of molasses orits equivalent proportion of saccharine matter or extracted liquor of grain to every one hundred pounds of hops employed,though these proportions are by no means arbitrary. The whole is then evaporated or condensed to the consistence of very thick molasses, after which it may be taken out and put into vessels for use or transportation.
