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.

Abstract: A weatherstrip seal comprises a carrier structure without reinforcement which has an attached weather-sealing structure extending therefrom. The carrier structure has two spaced-apart walls connected by a base forming an interposed channel which is partially filled with a foamed, hot-melt adhesive. The carrier structure is adapted to fit over an anchoring mounting flange, while the weather-sealing surface has a sealing surface that prevents the entry of the elements through joined components moveable relative to each other.
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.
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.
Abstract: A bone cement is prepared by synthesizing a polymeric composition comprising poly(methyl methacrylate) cross-linked by copolymerization with tris(.omega.-methacryloyl) polyisobutylene. A powder is formed from the composition, and the final cement is prepared by mixing the powder with additional methyl methacrylate in the presence of a catalyst to form a dough-like material that is polymerized in situ to yield a cement useful for orthopedic purposes. Preferred embodiments employ tris(.omega.-methacryloyl) compounds within a particular molecular weight range, and which are present in the powder in particular amounts relative to the poly(methyl methacrylate) component therein.

Abstract: A process for preparing poly(p-phenylene)s comprises reacting dihydroxy aromatic compounds such as orthoquinone and bisphenols with halogen-substituted aliphatic sulfonic acids, halogen sulfonic acid, or their anhydrides. The monomers thus formed are subsequently polymerized with Ni(0) catalysts to yield the desired polymers. The monomers or polymers may be functionalized with reactive groups.
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.
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.
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.
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.
Abstract: An appliance for preparing freshly brewed iced tea with microwave energy comprising a generally funnel-shaped reservoir of molded plastic construction having an open upper end, closed lower end and an aperture near the closed lower end. The reservoir is dimensioned to hold a predetermined amount of water and tea simultaneously. A valve arrangement controls the flow of liquid from the reservoir through the aperture and to move from a closed position to an open position after water in the reservoir has been heated by microwave energy to a predetermined temperature. A receptacle is dimensioned to hold the hot, brewed tea from the reservoir and a predetermined amount of ice, and includes a barrier to shield ice therein from microwave energy.
Abstract: A carousel device for collating product samples includes pivoting arms provided with suction cups attached to the ends thereof that swing in a first direction toward adjacent bins until the cups contact and attach to samples stored in the bins. The arms then pivot in the reverse direction to a position in which a hole in the sample is engaged by a pin attached to one of a plurality of trolleys propelled around the carousel and past the arms by a moving chain. The vacuum is released as the trolleys move onward to another set of arms where an additional sample is placed on the pin. The process continues as the trolleys make a complete circuit of the carousel and collect a collated set of each of the samples contained in the bins.
Abstract: An absorbent pad, such as a sanitary napkin, is provided having a fibrous facing sheet. The fibrous face is a fractional-denier fibrous nonwoven fabric which may or may not be laminated to a thermoplastic sheet, depending on its strength. The sheet is vacuum perforated to make it permeable to body fluids.
Abstract: A self supporting dome structure comprised of a plurality of rings connected one upon another, each of the rings approximating a conical frustum with successively higher rings having lower angles of inclination. Many of the rings are formed of a plurality of individual, flat panel, each of which includes a flat rectilinear top plate member, a flat rectilinear bottom plate member and opposed flat rectilinear side members, the side member converging inwardly from the bottom member to the top member.
Abstract: A device for fabricating toilet seat covers from paper sheeting comprises three paper shearing and folding assemblies positioned one over the other, each assembly including a drive roll, as well as two additional compression rolls which shear and fold the sheeting. Three layers of the sheeting are fed simultaneously through rotary cutting rolls, and subsequently to the drive rolls associated with each of the assemblies. While one of the layers is fed to the bottom assembly drive roll, a double layer of sheeting proceeds to the drive roll of the middle assembly. There the double layer of sheeting is separated, with one layer being fed to the drive roll of the top assembly, and other layer proceeding through the other compression rolls of the middle assembly. Completed covers exiting from the superimposed assemblies are collated and transferred by transport and collating belts to a transversely adjustable ejection mechanism where the covers are ejected from the device.
Abstract: An easily detachable and/or assembleable and/or longstandingly endurable luggage roller is provided. The roller includes a top plate mounting, or rotatably mounting, thereunder a hollow mounting medium having two dovetail-shaped wings having a lower width larger than an upper width, a shaft passing through the two wings for rotatably mounting a rolling medium in the hollow mounting medium, and two decorating pieces respectively engaging with two wings.
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.
