  • Patent number: 4463874
    Abstract: A dispenser for a stack of horizontally disposed, rectangular cards or the like and a product vending machine incorporating the dispenser. The dispenser features a magazine for the stack of cards and a dispensing chute beneath the magazine. Between the magazine and the chute, on one lateral side thereof, is a slider with a pair of laterally extending front and rear fingers that can be moved frontally and rearwardly against the front and rear edges, repectively, of the bottommost card of the stack. When the dispenser is actuated, the slider moves rearwardly so that its front finger urges the bottommost card to move rearwardly to an intermediate position in which the rear portions of the card are restrained from moving downwardly while the front portions of the card are free to move downwardly into the dispensing chute.

  • Patent number: 4457912
    Abstract: An electric razor preshave composition containing an effective amount of a cationic polymer. The cationic polymer is selected so that, when the composition is applied to hair to be shaven, the cationic polymer clings to each individual hair, and when the composition subsequently dries on the hair, the cationic polymer forms a relatively stiff but pliable coating on each hair. The dry cationic polymer coating makes each hair stay relatively erect during shaving and, in addition, neutralizes static charges on the metal blades of an electric razor so that the individual hairs are not repelled by the razor blades as they are being cut.

  • Patent number: 4338397
    Abstract: A method is provided for synthesizing within a bacterial host, and secreting through the membrane of the host, a selected mature protein or polypeptide. The method involves:(a) cleaving a cloning vehicle to form a cleavage site after a promoter of either (1) a bacterial or phage gene within the cloning vehicle or (2) a DNA fragment of the bacterial or phage gene;(b) forming a hybrid gene by inserting into the cleavage site a non-bacterial DNA fragment which codes for precursor of the selected protein or polypeptide, including the signal sequence of the selected protein or polypeptide;(c) transforming the host with the cloning vehicle; and then(d) culturing the transformed host to secrete the selected protein or polypeptide.By this method, mature proteins or polypeptides can be produced, free of signal sequences or other chemical substituents, such as an f-met, on the proteins or polypeptides.

  • Patent number: 4289125
    Abstract: Polymeric sheets having on one or both sides a fabric texture and, optionally, a network of elongated channels in the interior of the structural framework of the sheets. In one embodiment, the sheets comprise a plurality of interbonded continuous polymeric ribs extending in a direction parallel to the plane of the sheets. These ribs impart a fabric texture to both sides of the sheets and define between them recessed portions on each surface of the sheets. The elongated channels extend throughout the ribs. The open area between the ribs can vary from zero to 60%. In another embodiment, the sheets have an ultra-thin, pinhole-free polymeric membrane on one side and a fabric texture on the other side. The sheets are useful as burn coverings where they serve as synthetic, temporary replacements for damaged or missing skin.

  • Patent number: 4207302
    Abstract: A method for pretreating phosphoric acid to prevent the formation of a mass of suspended solids (i.e., "crud") during solvent extraction of the acid is described. Prior to solvent extraction, the acid is contacted with a liquid hydrocarbon such as kerosene which collects the crud-forming agents. The mixture of liquid hydrocarbon and collected crud-forming agents is separated from the acid and the liquid hydrocarbon is regenerated for reuse in the first step of the method.

  • Patent number: 4200488
    Abstract: An improved process for forming a non-woven fabric by wet-laying, on paper making equipment, staple length, synthetic fibers having a length to diameter ratio of about 400 to 3000, and an improved, non-woven fabric produced by the process. The process involves forming a stable, viscous, uniform, air-fiber-water dispersion by: adding the fibers to a high-shear agitated mixture of water and a dispersant to separate the fibers and to completely and uniformly distribute the individual fibers throughout the resulting, high-shear agitated, air, water and fiber mixture; and then, slowly adding a thixotropic thickener to the high-shear agitated mixture to form the viscous, air-fiber-water dispersion, having a nascent viscosity of about 10 to 125 cps., when measured at a shear rate of 30.5 sec..sup.-1, and in which the individual fibers are restrained from becoming entangled and from forming knits, bundles, and strings.

  • Patent number: 4166877
    Abstract: A process and device useful therein for hydraulically entangling the fibers in a fiber batt to form a fiber-entangled base sheet for a non-woven fabric, and a uniformly and lightly fiber-entangled, base sheet formed by the process. The process includes applying at least one liquid curtain against the fiber batt while it is supported on a moving, apertured backing screen. The liquid curtain is uniform in width throughout its length and substantially non-diverging as it is delivered from a source of liquid under a pressure sufficient to effect entanglement of the fibers in the batt. Preferably, the pressure is at least about 200 p.s.i.g., and the maximum divergence of the curtain is about 4 degrees. The device for applying the liquid curtain includes first and second members and means for securing the members together to form a chamber therebetween in which the liquid is contained and to form a slot in communication from the chamber to the exterior of the device.

    Abstract: A mechanical anti-wheel lock-up control system for avoiding wheel lock-up and consequent skidding in a motor vehicle, including a lock-up sensor or control device arranged in an open end of the axle tube and protectively covered over by the hub cap of the wheel, the control device being of an inertia flywheel actuable valve type controlling relief from and application of service air to the braking mechanism, the control device having an input shaft associated with the flywheel by means of an axially disengageable cam clutch and geared to be driven by the hub cap. The control device may be employed in a system individual to each wheel, or in a system serving a plurality or pair of wheels. In the latter, a control module of valves modulates the pressure of service air feeding to the braking mechanism in controlling a wheel lock-up condition.
