Abstract: The present invention provides a wall for a package, which wall comprises, or includes a layer comprising, a composition comprising a polymer and capable of scavenging oxygen through the metal-catalysed oxidation of an oxidisable organic component thereof. The oxidisable organic component is preferably itself a polymer, and may be the only polymer in the composition. Preferred compositions include a blend of 96% polyethylene terephthalate and 4% poly (m-xylyleneadipamide) containing 200 ppm cobalt as catalyst, with good permeance-versus-time performance (3) when formed into a bottle.

Abstract: A reel assembly for an electrical cable wherein the electrical cable is de-energized during winding and unwinding thereof.

Abstract: A multi-function safety service valve operable both manually and automatically through a toggle fuse-linked joint as located to interconnect the piping of an LP Gas bulk storage tank and a flexible hose connected to fill an LP Gas transport tank on a truck.

Abstract: This invention is a snap lock structure used with paper or plastic bag members to close an open end in a sealed, airtight manner. The snap lock structure includes an upper clamp member integral through a connector section with a lower clamp member. The upper and lower clamp members are similar, each having a main body and outer clamp sections. The upper clamp member has an outer lock head portion which engages in a locked condition a lock receiver portion of the lower clamp member. The connector section has a shield member to maintain the bag members in proper position for clamping.

Abstract: An internal combustion engine of the spark or diesel ignition type and having an anti-pollution arrangement for the reduction of the products of incomplete combustion and crankcase evaporation and said arrangement including a turbine adapted to receive exhaust gases and being connected to the engine through an overriding clutch to drive the turbine yet allowing for overriding faster rotation of the turbine through secondary ignition of the exhaust or other unburned gases. The turbine includes a fuel supply to aid in ignition of exhaust gases and may include a fuel supply with an aromatic indicator fluid which loses its aroma upon oxidation at a predetermined temperature thereby indicating if the turbine temperature is high enough to completely eliminate unburned exhaust and other gases without recycling said gases through the engine.

Abstract: A vehicle shock absorber is provided and includes a cylindrical shaped housing rotatably mounted on a central sleeve on a shaft on a vehicle body. A shock absorber band which assumes a circular shape in the form of a leaf spring is disposed around the inside of the housing periphery. One end of the shock absorber leaf spring may be fixedly attached on the housing inner periphery; the other end of the shock absorber spring is connected to a flexible chain passing around a roller in the housing and connecting with a rotatable sleeve which has a cam surface about which the chain can be wound. An elongated steel leaf spring is connected by a flexible belt to both the outer periphery of the housing and to a wheel and axle means. The chain winding sleeve is rotated about its associated shaft for adjusting the tension on the belt for proper shock absorber cushioning effect. The cylindrical shaped housing is held on the supporting sleeve by an adjusting and locking nut.

Abstract: A demodulator produces mark and space signals in response to mark and tone signals received from a radio receiver. The signals after detection are in the form of characteristic tones and are separated by corresponding band pass filters. After separation, AM detection of the mark and space signals is accomplished in envelope detectors whose output voltages are D.C. voltages. In the absence of noise, the detector voltages are essentially a rounded off version of the binary signal (mark) and a rounded off version of the complement (space) of the binary signal.
