  • Patent number: 4324353
    Abstract: Static tow inverting apparatus for inverting the overlap of overlapping layers of a continuous length filamentary tow band of textile material deposited onto the surface of a moving conveyor in relaxed condition for treatment, such as in the thermal heat setting treatment of a band of tow which has been subjected to a mechanical crimping operation. The tow inverter comprises a pair of stationary plates which are disposed above the surface of a moving conveyor to receive a continuous length of tow in a plurality of overlapping layers thereon. The opposed surfaces of the spaced plates define a downwardly curving passageway for gravitational conveyance of the overlapping layers of tow through a reversing direction of movement to deposit the same on the surface of the moving conveyor with preceding layers of tow overlying succeeding layers of tow in the direction of movement on the conveyor.

  • Patent number: 4300502
    Abstract: A fuel economizer system and fuel flow control valve arrangement for an internal combustion engine having a fuel supply tank, a main fuel supply line connecting the tank to the carburetor inlet of the engine, and a fuel pump in the supply line for delivering fuel to the carburetor inlet. The control valve arrangement is located in the fuel supply line between the fuel pump and the carburetor inlet, and includes a first control valve which is automatically incrementally adjusted between closed and open position by a diaphragm motor which is operatively connected to the intake manifold of the engine such that changes in vacuum in the intake manifold automatically adjust the control valve to proportionally increase or decrease the supply of fuel to the carburetor inlet.

  • Patent number: 4287305
    Abstract: Live metabolically active microorganisms are immobilized on a solid support by contacting particles of aggregate material with a water dispersible polyelectrolyte such as gelatin, crosslinking the polyelectrolyte by reacting it with a crosslinking agent such as glutaraldehyde to provide a crosslinked coating on the particles of aggregate material, contacting the coated particles with live microorganisms and incubating the microorganisms in contact with the crosslinked coating to provide a coating of metabolically active microorganisms. The immobilized microorganisms have continued growth and reproduction functions.

  • Patent number: 4224096
    Abstract: Thermoplastic materials, particularly material in sheet form, may be sealed or thermowelded together using the energy from a single laser beam source by splitting the beam and directing it by mirrors to desired seal areas on the opposed sides of the materials to be sealed. The beam may be split in proportion to the thickness of the respective materials. Heating the opposed sides of materials to be sealed avoids the problem of overheating or burning the side to which energy is applied.

  • Patent number: 4218486
    Abstract: In the preparation and storage of cooked, bulk packaged food in flexible receptacles, the quality of the food is increased, the cooking conditions are closely controlled, the growth of bacteria is restricted, and the storage time is increased by reducing the interior temperature of the food from its filling temperature of at least F. to below F. in less than a half hour. Said temperature reduction is preferably achieved by filling the receptacle so that the food therein is flowable or mobile and then tumbling the receptacle in a cooling medium so that the food flows or moves within the receptacle. After storage at F. to F., the food may be heated by tumbling the receptacle in a heating medium in order to bring the food quickly to serving temperature thereby avoiding overcooking.

  • Patent number: 4208855
    Abstract: To provide a hermetic seal for flexible receptacles such as plastic bags, pouches, or casings, the outside of the mouth of the receptacle is coated with a cold flowing resin so that when the receptacle is filled and its mouth gathered under pressure the resin will cold flow and fill the voids in the gathered folds. Preferably, the end of the gathered mouth is trimmed and then high pressure is applied to cause the resin to exude from the trimmed end. Next, a forming plunger is used to press the exudate into a smooth surface whereby a fused cap of resin is formed hermetically closing the bag's mouth. As an alternative, a clip or band can be placed around the gathered end under sufficient pressure to case cold flow of the resin thereby sealing the voids.
