  • Patent number: 5626383
    Abstract: A weatherstrip seal comprises a carrier structure without embedded reinforcement that has an attached weather-sealing structure extending therefrom. The carrier structure has two spaced-apart legs connected by a base, the interior walls of the legs forming a channel therebetween. Finger-like members extending from the walls are adapted to frictionally engage and hold a mounting flange inserted into the channel. The legs decrease in thickness as they proceed outwardly from the base and their walls converge inwardly toward each other, minimizing the material required for fabrication of the carrier and enhancing its ability to withstand forces acting to dislodge the mounting flange from the channel, especially at corners thereof.

  • Patent number: 5338011
    Abstract: A torque strut for an automobile engine is described as having a unique energy absorbing housing in which is mounted a unique energy absorbing device which has a block-shaped center piece from which a pair of resilient rubber shock absorbers extend in opposite directions for receipt in a pair of adjacent cavities which are formed in the housing. The farthest spaced opposing ends of the rubber shock absorbers are free of the housing, but are designed to compressively engage adjacent ends of the cavities and fill the cavities when the shock absorbers are compressively expanded in the cavities, as a result of forward or reverse roll of the engine. A rolling rubber torus with a special mechanism for interlocking engagement with the device, is provided to stabilize the position of the energy absorbing device within the housing of the torque strut.

  • Patent number: 5308582
    Abstract: A hypodermic syringe uncapping device includes a housing enclosing two opposed, pivotal arms adapted to grip a cap protecting a hypodermic syringe needle. Upon insertion through a hole in the housing, the capped needle is forced against a movable plunger whose lower end engages one of a number of pins extending from the surface of a rotatable cam located between the arms. Rotation of the cam thus induced allows the arms to pivot toward each other under the urging of an arm-connecting spring, causing the arms to grasp the cap and thereby allow subsequent withdrawal of the needle. When the needle is reinserted in the cap and the cap is again pushed against the plunger, the cam is rotated still further, forcing the arms apart and permitting the cap to be withdrawn from the device.

  • Patent number: 5238992
    Abstract: A process for preparing solid polymer blends and composites of controlled porosity in microemulsions containing both hydrophilic and hydrophobic phases. The microemulsions are prepared with surfactant systems that may include a cosolvent as a part thereof, together with a hydrophilic monomer, or monomers, dissolved in the hydrophilic phase of the microemulsion, and a hydrophobic monomer, or monomers, dissolved in the hydrophobic phase. Polymerization of the monomers thus present is carried out to provide highly uniform dispersions of the resulting polymers in each other. The invention allows for the control of the morphology of the blends, the improvement in compatability of otherwise incompatible polymers, and improvements in the processability of the polymers due to enhanced thermal and mechanical properties.

  • Patent number: 5191047
    Abstract: Enamine ketone and enonesulfide polymeric solids are prepared by reacting liquid or low-melting propynone terminated enamine ketone and enonesulfide prepolymers in one-step, or more preferably, in two-step processes. Properties of the resulting polymers are determined by the nature of the reactant selected and by the relative amounts of reactants employed. Where the prepolymers formed possess terminal propynone groups, the prepolymers can subsequently be cross-linked. Copolymers can also be formed by reacting the prepolymers of the invention with vinyl-type monomers to form polymers with cross-linked networks. The polymerization techniques disclosed can be employed to produce thermoplastic, thermoset, and elastomeric products, and they are especially useful in reaction injection molding processes, in adhesive systems, in composite formations, for linings, and gaskets which require chemical resistance.

  • Patent number: 5188207
    Abstract: A coin mechanism for a vending machine comprises a cylinder rotatable in a passageway within a housing to release vended product to a purchaser. Operation of the mechanism requires insertion of purchase coins into coin slots accessible when the cylinder partially protrudes from the housing. The cylinder is thereafter substantially completely inserted into the housing and rotated by means of a handle located on one end thereof. Upon rotation of the cylinder, the coins prevent engagement of locking pawls mounted in the housing with either of two separate mechanism-blocking shoulders located on the cylinder. The end of the cylinder opposite the handle is connected to a coupler member, which in turn is fastened to a spiral product coil, rotation of the cylinder causing rotation of the coil and the release of product therefrom. The coupler member also includes a ratchet wheel which cooperates with a pawl in the housing to prevent improper rotation of the cylinder.

  • Patent number: 5188387
    Abstract: A ski binding release mechanism that includes both an electronic and a mechanical release mechanism. The mechanical release mechanism incorporates a delay feature that allows it to function only if the electronic mechanism experiences a failure. The delay feature is provided by a cylinder movable with respect to a stationary piston positioned therein, the piston dividing the cylinder into two chambers. Movement of the cylinder, required to release the soleholder of a ski boot, is retarded by the time required to pass liquid in the cylinder from a first of the chambers to a second of the chambers through a choke passage in the piston as the cylinder moves. Movement of the cylinder is caused by a plunger connected to the soleholder of the ski binding that urges against the cylinder under the influence of a sustained, predetermined, potentially hazardous force acting on the binding.

  • Patent number: 5161330
    Abstract: A side adjustable roller assembly for a sliding door comprises a housing containing a rotatable cam and a wheel carriage with a guide wheel mounted therein pivotally attached to the housing. The assembly is insertable into a recess in the edge of a door, being held therein by a slot in one end of the housing, and by a bend in a strip of spring steel attached to the housing at the other end which engage opposite ends of the recess, respectively. Contact of the cam surface with that of the wheel carriage controls the distance that the carriage can be pivoted into the recess by the door's weight, against the force of an associated spring urging the carriage away from the recess. The point of engagement of the cam surface with the carriage, and therefore the distance between the door's edge and the surface over which it is mounted, depends upon the degree of the cam's rotation, determined by adjustment of cam mounting trunions which can be accessed from the side of the housing.
