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.

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.

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.

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.
