  • Patent number: RE29571
    Abstract: The specific disclosure provides a dispensing system for razor blade cartridges comprising a dispenser, a plurality of cartridges in the dispenser, and a holder having a plurality of transverse supporting surfaces on top of a frame member for sliding engagement with surfaces extending transversely of each cartridge. The dispenser has a used cartridge storage end comprising a transverse opening between a used cartridge entrance port in one side wall and a holder exit port in the other side wall. A used cartridge is positioned in the used cartridge storage end through the used cartridge entrance port by means of the holder. The frame member of the holder is moved through the transverse opening to abut a side of the used cartridge against wall surfaces forming the holder exit port. Continued movement of the holder disengages the transverse supporting surfaces of the holder from the used cartridge, and such holder surfaces are removed from the storage end through the holder exit port.

  • Patent number: RE29574
    Abstract: A plaything comprising two mug-shaped receptacles and a linear flaccid line which may be a cord, a chain, a string of beads, or the like. One end of said line is held inside one receptacle, and the other end of said line is held inside the other receptacle, both of said receptacles being at least large enough to house substantially all of said line. Prior to using the plaything, the two receptacles are placed side by side on a horizontal surface and substantially all of said line is hand-fed into one receptacle so as to be amassed in a heap with the last fed-in parts resting on top of the previously fed-in parts. Then, when the receptacle housing most of said is positioned above the other receptacle, said line -- because of gravity -- will run from the upper receptacle into the lower receptacle. When most of said line is amassed in a heap in the lower receptacle, the positions of the receptacles are interchanged and the direction of running of said line reversed.

  • Patent number: 4078275
    Abstract: An upright-type vacuum sweeper has a motor-driven fan in a housing supported by a pair of front wheels on an axle which is vertically adjustable to vary the nozzle height relatively to a floor surface. A ratchet member having two parallel arcuate sets of teeth constitutes in part a lever for effecting the relative movement. A foot-depressible spring-returnable vertically disposed plunger carries a pawl-type escapement element which reciprocates between the sets of teeth to permit stepwise lowering by gravity of the housing and thus the sweeper nozzle. A foot-depressible ratchet-swinging lever provides one-stroke elevation of the housing. Novelly an adjustable screw is positioned to limit downward movement of the housing to provide a vernier adjustment in the low end of the nozzle-adjustment range to facilitate pushing the sweeper, especially over short-nap floor coverings which have been found to produce bothersome frictional resistance to sweeper movement.

  • Patent number: 4078276
    Abstract: A hinge pin including two substantially identical sections which when assembled form a cylindrical sleeve. Each section has a first end having a cross-section greater than a semi-circle which tapers along its length to a second end having a cross-section less than a semi-circle. When the two sections are joined together, they form a cylindrical sleeve for use as a readily removable hinge pin. Ready removal is effectuated by sliding one section away from the other along their tapered lengths, the taper enabling the average diameter of the sleeve to decrease as the two sections are so slid apart.

  • Patent number: 4078279
    Abstract: A slide fastener with separable endstop members has a pair of stringer halves with respective rows of coupling members or heads adapted to interdigitate upon movement of a slide therealong. At an end of the stringer one of the slide fastener halves is provided with a pintle while the other slide half has its endstop member formed with a knuckle enabling one endstop member to pivot about the pintle axis relative to the other laterally and into the slider preparatory to closure of the slide fastener. A hook on one of the endstop members remote from the pintle engages the other endstop member to hold the two together. According to the invention, one of the endstop members forms a double armed lever fulcrumed between the pintle and the hook so that, upon engagement of the hook, the pintle is retained forcibly against its seat.

  • Patent number: 4078284
    Abstract: A method of fabricating a lead titanate piezoelectric surface acoustic wave substrate comprises combining lead oxide, titanium tetra-n-butoxide, lanthanum oxide, and manganese dioxide, with a hydrocarbon solvent and adding water to the combination to form a slurry in which titanium polyester is precipitated unto the lead oxide and lanthanum and manganese oxides. The slurry is dried by heating to a temperature sufficient to remove the liquids therefrom but below the temperature at which an exothermic reaction between the included hydrogen, oxygen and carbon occurs. A first calcining operation produces the exothermic reaction and forms lead titanate after which the lead titanate is heated to and maintained at a temperature above that produced by the exothermic reaction. The lead titanate is then ground to produce powdered lead titanate and a second calcining is carried out to produce structural annealing of the powdered lead titantate.
