IPC: B65D75/02
Filed: 1992-04-01
Abstract: ABSTRACT        An improved form of point-of-sale packaging for a hand tool, comprising a sleeve which fits around the tool, but will not fall off of it in the store.  It is likewise difficult for a customer to remove the sleeve in the store and substitute it with the packaging of a similar product.  The packaging may be made from cardboard.  In one embodiment, it comprises an integrally formed loop, which is fitted around the tool (such as a combination square) during assembly, but cannot be separated form it without disassembling the tool, or visibly damaging the packaging, which would be indicative of tampering.  In a second embodiment, the packaging comprises a multi-paneled sheet, which is folded around the tool (such as a hand level) and into an aperture therein like a hand hold, where the sheet is fastened upon itself into an integral loop.          This packaging may not be removed from the tool without unfastening it to sever the loop and, again, visibly showing evidence of tampering.

Title: Method and apparatus for processing fish heads
Inventor: SIGURDSSON ARNI M
IPC: A22C25/14
Filed: 1992-04-29
Abstract: A method and apparatus for cutting tongues, cheeks and belly flaps from fish heads and for cutting apart jaws of fish heads. The fish head is mounted on a reinforced beam beneath a spiked chain which moves the head along the beam, first towards horizontal knives which cut the tongue from the head, and then to vertical knives which cut the cheeks and the belly flaps from the head. Over the tongue knives are jaw rods which hold the jaw up to the beam adjacent the tongue knives. Inside the beam is a stick which can be driven down from the beam to locate the tongue in a cutting position below the tongue knives. The head hits a sensor which activates a power source for the stick. The belly flaps are held up by belly flap rods, which lie beneath the collar bones and keep the belly flaps from the tongue knives. The cheeks and belly flaps are cut off with two vertical cheek knives. Behind the cheek knives, there is a vertical step on the belly flap rods which support the belly flaps while the knives cut the cheeks and belly flaps. The jaw is then cut apart with a jaw knife located on the beam. One of the jaws then falls down a sliding chute which moves the head up and off the beam and then falls into a vat for bones.

Patent CA-2073058-A1 (CA)
Title: Treatment of metals for coating or activation
Inventor: BALDI ALFONSO L
IPC: B22F7/00
Filed: 1990-09-13
Abstract: Coating with high-melting metals can be simplified by alloying high-melting metal with sufficient aluminum to make low-melting alloy that is applied, bonded in place, and then subjected to the leaching out of some or most of the aluminum. The resulting surface is porous and will receive and hold tap coatings as from spraying nozzles (12). Leached surface can be pyrophoric and top coating can be exothermically combustible. Pyrophoric powder can also be coated on boron or carbon fibers or sintered with combustible particles. Porosity can be created by subjecting workpiece to diffusion conditions in contact with depleting material such as powdered nickel or high-nickel aluminides or cobalt or high-cobalt aluminides. Aluminum particles can be electrophoretically deposited on foil and then diffused in. Leaching aluminum out with caustic is improved when a little H2O2 is present in the caustic in the leach tank (22). Subsequent treatment of the leached surface with weak acid further improves pyrophoricity, and folding of the pyrophoric member extends its pyrophorically-generated high temperature dwell. Resin foil containing pyrophoric particles makes effective decoy,

Patent CA-2073678-A1 (CA)
Inventor: GROOMS JOHN M
IPC: G05D16/16
Filed: 1991-10-31
Abstract: An improved vacuum sewerage system for transmitting sewage through an intermittently opened sewage control valve of a transport conduit by means of differential pressure. The vacuum conduit is laid out in a saw-toothed fashion, having a riser, a low point, and a downslope. When no sewage is being transported through the conduit, any residual sewage in the conduit collects in the low point, with minimal intermittent closure of the conduit over time to permit minimal drop in vacuum or subatmospheric pressure throughout the conduit such that there is more than adequate vacuum or subatmospheric pressure available to operate the control valve. When the control valve is opened, the sewage transported through the vacuum conduit forms a generally hollow cylindrical mass, which is propelled toward a vacuum collection tank. The system includes an electric air admission controller ("EAAC"), which automatically opens and closes an air control valve independently of the level of accumulated sewage upstream of the sewage control valve, in order to inject additional air at atmospheric pressure into the vacuum transport lines to apply additional fluid pressure to a mass of sewage therein, and to avoid a waterlogged condition by supplementary transport. A conduit line having more than 13 feet of total lift is thereby possible, provided that the sum of the pressure losses across all the risers equals or exceeds the sum of the minimum subatmospheric pressure condition available at the vacuum collection station minus the pressure head required to operate the control valve.

Title: Tip clearance control apparatus for a turbo-machine blade
Inventor: EVANS DAVID H
IPC: F02C7/28
Filed: 1993-01-20
Abstract: 57,162 ABSTRACT An apparatus is provided for controlling rotating blade tip clearance in a turbo-machine utilizing conical tipped blades.   The apparatus comprises an approximately conical blade ring mounted for axially sliding displacement in the turbo-machine cylinder.   The  conical  blade ring encircles the tips of the rotating blades and forms a blade tip clearance therebetween.  The tip clearance is controlled during operation of the turbo-machine by axially displacing the  conical  blade ring.   Piston  cylinders,  actuated by pressurized fluid extracted from the turbo-machine, are used to displace the blade ring.   Springs, adapted to bias the blade ring into a position of increased tip clearance, oppose the piston cylinder so that failure of the piston cylinder will not result in a loss of tip clearance.   A blade tip clearance sensor transmits information on the tip clearance to a controller that automatically adjusts the blade ring axial position to continuously maintain the optimum tip clearance by regulating the pressure of the fluid supplied to the piston cylinders.
