  • Patent number: 4456507
    Abstract: Described is an aqueous chip resistant coating composition exhibiting a viscosity of at least 5,000 centipoise, preferably containing binders with a high molecular weight, preferably at least 20,000. Although these coatings may be applied to a variety of substrates, for coating electrocoated substrates the following eight binders are particularly preferred: ethylene vinyl acetate copolymer, carboxylated ethylene vinyl acetate, epoxy functional acrylic resin, carboxylated styrene-butadiene resin, carboxylated acrylic, hydroxy functional acrylic, self-crosslinking acrylic; and carboxylated PVC acrylic. Generally, it is preferred to apply the chip resistant coating via an airless spray and then heat curing the coating.

  • Patent number: 4454871
    Abstract: An easily removable ankle-foot orthosis 11 is formed by molding an inner liner of plastazote foam 24 and an outer layer of polypropylene gel 25 to a positive shaped mold 10 of the foot 12 and lower leg 14. The positive mold includes a pair of opposed protruding longitudinal ribs 18, 20 disposed alongside the lateral and medial surfaces of the lower half of the leg to below the ankle. The resulting orthosis, which comprises an open-toed boot-shaped structure formed having a continuous longitudinal frontal opening 46, is adapted for securely maintaining the foot and leg of a wearer in a slightly less than 90.degree. relationship to one another, the rigidity of the orthosis being enhanced by the longitudinal ribs formed therein. The orthosis is easily removable through use of the frontal opening and may include a plurality of transverse binding straps 50 for snugly fitting a single orthosis to a variety of foot and leg sizes.

  • Patent number: 4440181
    Abstract: The invention is a nail polish remover kit for removing nail polish from fingers and toenails. The kit has a pear-shaped jar containing a nail polish remover saturated filler. The filler is constricted at the top by the constricted upper portion of the jar to prevent both rotation of the filler and visual sighting of the sludge at the bottom of the jar, produced by nail polish removal process. The filler possesses an opening for inserting a finger having a nail from which polish is to be removed. The opening may be formed from filler surfaces which are smooth or uneven, and, if uneven, preferably corrugated. The opening is dimensioned so that excess nail polish remover is wiped from the finger as it is removed from the filler. The kit also contains a dauber with an absorbent end that the filler opening is designed to receive. This dauber may be removed from the filler to remove polish from toenails, fingernails, and the like.

  • Patent number: 4432111
    Abstract: The invention concerns a procedure and a mechanism for washing textiles in a tub-type washing machine with a horizontally arranged tub, in which during the washing and rinsing cycles the tub is driven with a rotational velocity at which the centrifugal velocity at the tub case is between 0.4 and 0.95 g, so that the textiles are repeatedly lifted up, and then fall in a trajectory onto the lower portion of the tub, and that between the washing and rinsing cycles and after the last rinsing cycle the tub is driven at spin speed, and in which the washing or rinsing liquid is led into the suds container and is supplied to the textiles by immersing the tub in the liquid or by at least one spray nozzle spraying into the tub continuously or at intervals.

  • Patent number: 4430891
    Abstract: A method and apparatus for measuring the volume of a chamber in a part, such as the combustion chamber of an internal combustion engine cylinder head by, comparing the test chamber with a reference chamber of known volume, wherein the reference chamber is exposed to the part containing the test chamber so that ambient variables are minimized, and accurately controlled quantities of a gas are injected into each chamber and the difference in pressures in the chambers read as a function of test chamber volume, and thereafter the rate of change of pressure differences in the chambers is read as a function of chamber leakage and the volume measurement discarded if the rate of change exceeds a determined value.
