Today in 1968, US Patent 3366033 A was issued, an invention of Laurence Robert Bishop, assigned to Watney Combe Reid & Co Ltd, for his “Brewing of Beer.” There’s no Abstract, but the description states that the invention is not so much a new method for the brewing of beer — as the title suggests — but instead is “an apparatus for segregating lupulin from dried hops including a pin mill into which the dried hops are introduced and subjected to disintegration and means for conveying the disintegrated material from the pin mill to a sifting means in which the lupulin is sifted from the discarded plant tissue.”
