Patent CA-2084892-A1 (CA)
Inventor: ANDERSON PAUL S
IPC: A23J3/04
Filed: 1991-05-29
Abstract: A particulate proteinaceous product and methods for producing the same from waste raw animal parts are disclosed. The product is dry to the touch, is compressible into pellets or cakes, and comprises about 45 to 65 w/w percent partially hydrolyzed, non-denatured animal protein, about 20-35 w/w percent oil derived from the animal parts, about 10-15 w/w percent moisture, and about 0-7 w/w percent ash. The product also has less objectionable odor, less propensity to oxidize, and higher nutritional value than existing products. The method comprises a mulling stage wherein the raw animal parts are reduced to a ground condi-tion; a hydrolyzing stage wherein proteins in the ground animal parts are hydrolyzed to a predetermined extent to form an aque-ous suspension, using either endogenous or supplementary proteolytic enzymes, and subsequently heated to inactivate the en-zymes and convert fats in the suspension to oils; a screening stage wherein non-digestible solids are removed from the suspen-sion; a concentration stage wherein extraneous oil is added to the suspension, the suspension is pasteurized, and a large portion of the water is removed therefrom; and an oil-separation stage wherein sufficient oil is removed to form the product. A portion of the removed oil is routed back to the beginning of the concentration stage as extraneous oil added to the suspension to permit suf-ficient water to be removed from the suspension without forming a stiff, unprocessable mass. The method is distinctive in that it produces a dry, flaky product without the use of a conventional dryer. The method is also distinctive for its substantial resistance to equipment clogging.

Title: Arthroscopic sheath with quick coupling socket
Inventor: SHUTT GEORGE V
IPC: A61B1/06
Filed: 1990-01-26
Abstract: A tubular arthroscopic sheath having improved irrigating fluid flow characteristics and having a quick coupling socket adapted to quickly connect to and disconnect from an associated arthroscopic tool provided with a mateable, generally cylindrical plug member.  The fluid flow is enhanced by centering projections on the sheath interior and by turbulence minimizing fluid ports. The socket comprises an open ended cylindrical housing provided with a plurality of annularly spaced, cylindrical locking pins slidable within throughbores in the housing wall, the throughbores extending radially from the housing axis and axially skewed with respect thereto.  Each pin is provided with a notch in its cylindrical surface adjacent the most radially outward end of the pin.  A pair of slidable coaxial cylindrical actuating members is adapted to engage all the notches and capture the pins.  Moving the slidable actuating members away from the open end of the housing causes the pins to slide radially outwardly in the throughbores.  Allowing a bias means to urge the actuating members toward the open end of the housing causes the pins to slide radially inwardly.

Title: Coating apparatus for sheet-fed rotary offset printing presses
Inventor: DEMOORE HOWARD W
IPC: B41F13/00
Filed: 1993-04-22
Abstract: ABSTRACT           A coating apparatus for use in a sheet-fed or web-fed, offset rotary or flexographic printing press to apply a protective and/or decorative coating to the surface of freshly printed sheets includes a doctor blade coating unit  coupled to  a pickup  roller  for  supplying  liquid material from a remote supply drum to sheets transported on the surface of a transfer/delivery cylinder mounted on a press delivery drive shaft.  Liquid material is circulated through the reservoir of the doctor blade unit by suction flow produced by a return pump.  This prevents the buildup of positive pressure within the doctor blade reservoir.          The doctor blade reservoir is maintained at below ambient pressure level, thereby inhibiting leakage through the end seals.  A  vacuum  sensor  assembly  provides  a  visual indication of air vacuum pressure  in the doctor blade reservoir chamber,  and a vacuum sensor  switch applies electrical  power  to  an  audio  transducer.    The  audio transducer produces an audible alarm in response to an increase  in  doctor  blade  chamber  pressure,  thereby providing advance warning of an impending end seal failure or a worn doctor blade condition.

Patent CA-2097963-A1 (CA)
Title: Biomass mortar system
Inventor: ROBINSON BRADLEY
IPC: C04B18/30
Filed: 1993-06-08
Abstract: ABSTRACT A building material and system is described in which a biomass concrete or mortar is formed of shredded waste, clay, sand, and cement, so that a load-bearing biomass matrix hardens that is capable of distributing load three-dimensionally while retaining good flexibility and insulating qualities. In an example such biomass mortar is poured around rounded pellets to form a wall, which is later faced with parging externally and masonry internally, to make a thermal resistant, air-flow-controlled compressive structure, preferentially with a continuous vaulted poured roof, that is an advance on previous biomass wall systems. Savings in the amount of cement used can be as high as 90%, and a use is provided for all types of consumer, commercial, agricultural, and construction waste, even without sorting, since small amounts of metals and hazardous substances can be accommodated by the shredding, oxygenation, and curing of the biomass mortar, and further by the air-flow control of the internal facing, where such is used.

Patent CA-2101290-A1 (CA)
Title: Eas system with improved processing of antenna signals
Inventor: PLONSKY CHRISTOPHER B
IPC: G06K19/07
Filed: 1993-07-26
Abstract: An EAS system in which first and second received signals are independently front-end processed to produce third and fourth signals indicative of the absolute values of the first and second processed signals. The third and fourth signals are then combined and the combined signal passed to a tag evaluation processor for time and frequency domain processing for evaluating whether a tag is present in an interrogation zone. The front-end processing is carried out in such a way that interference signal content including shield interference is extracted without extracting tag signal content in the received signals over a period of time. In this way, the first and second transmitter antennas of the system can be driven with drive signals having a phase difference of other than 0° or 180° and the tag evaluation processing can be carried out during the entire period of the drive signals.

Title: Miniaturized solenoid operated trip device
Inventor: PIPICH CHARLES W
IPC: H01H71/24
Filed: 1994-01-28
Abstract: MINIATURIZED SOLENOID OPERATED TRIP DEVICE          Abstract of the Disclosure A solenoid operated circuit breaker trip device has a base defining a guide channel and an actuator that slides in the guide channel and interacts with a contact breaking mechanism having a trip bar operable to make or break electrical contacts.  A spring biases the actuator toward the trip bar.  A solenoid on the base electromagnetically displaces a plunger along a linear path and is coupled to a trigger having a latching surface that holds or releases the actuator.  The guide channel runs parallel to the path of the plunger, adjacent the solenoid.  The trigger is L-shaped and pivoted on a pivot pin between two legs of its L-shape, on an axis transverse to the path of the plunger.  One of the two trigger legs is coupled to the plunger,  and the other has an engagement surface that is moved behind a complementary surface of the actuator to selectively block its displacement.   The base can be a slotted frame attached to the solenoid or a molded housing having an interior cavity for receiving the solenoid.  A return spring urges the trigger toward the latching position.
