Abstract: A continuous steady state flow process for converting proteinaceous materials by reacting the proteinaceous materials with coagulants or other precipitants in situ. Streams of proteinaceous materials and coagulants are fed into an introduction chamber under a predetermined pressure and are directed through an orifice as a high velocity jet stream into a resonance chamber to impinge against a vibratile element. The energy from the jet stream is transferred to the vibratile element to cause it to vibrate at high sonic or ultrasonic frequencies. The high sonic or ultrasonic energies are transferred to the mixture of proteinaceous materials and coagulants to produce a cavitational effect and cause instantaneous reaction and homogenization of the proteinaceous materials and coagulants to thereby form a protein matrix.

Abstract: A process and apparatus for automatically and continuously cutting hog carcasses into primal cuts includes means for moving the hog carcasses in a predetermined path of travel. The carcasses are first separated into carcass sides and are conveyed on adjustable support mechanisms. Optical scanning devices view each primal cut portion of each carcass to locate a reference structure on the primal cut portion. The scanned reference structure is compared to a programmed cut pattern by a computer which controls operation of a plurality of cutting devices. The cutting devices are adjusted in response to the comparison of the scanned reference structure of the primal cut with the pre-programmed cut pattern. The computer program will include many cut patterns for each primal cut. The computer may be programmed daily, or in more frequent intervals, to select a particular cut pattern for each primal cut. The computer selects the desired cut pattern which has been predetermined for that particular time.

Abstract: A process and apparatus for dry lens generation of a plastic optical lens includes a chamber structure in which the lens grinding tool and the lens blank holder are positioned. The chamber is provided with a large unobstructed inlet and an outlet connected in communicating relation to a vacuum system so that the high volume, high velocity stream of ambient air is directed across the interface between the grinding tool and the lens blank to thereby entrain the cut plastic material in the stream for evacuation through the outlet. The grinding tool is diamond plated and the spacing between the diamond elements is of a sufficient magnitude to permit single point cutting of the material to thereby eliminate any tendency of the material to adhere to the grinding tool. A misting nozzle discharges a fine lubricating mist across the lens blank grinding tool interface when a lens is being formed from polycarbonate.
