摘要:
An adhesive composition using as the primary binder an emulsion of butadiene-vinylidene chloride copolymer is disclosed. The composition is particularly suited for binding rubber to metal in a variety of uses such as vibration damping devices. The adhesive composition has resistance to hot water and or water glycol solutions.

A hollow rubber play ball is disclosed that uses a combination two or more fillers to produce desirable playing properties in a tennis ball as specified by the International Lawn Tennis Federation (ITF). The preferred play ball is a pressureless tennis ball. The specific fillers disclosed are mineral type particulate reinforcing fillers such as silicas and carbon black, polymeric fillers such as cellulose, a reaction product of grafting polyethylene with cellulose, and ethylene-vinyl acetate copolymers. These fillers can also have surface treatments to enhance the elastomer-filler interaction. Another reinforcing filler that can be introduced with the rubber components is the non-rubber constituents in skim rubber that serve to increase the modulus of a compounded rubber.

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.

A clasp includes releasibly interconnectible first and second clasp members. The first clasp member includes an outwardly extending lock member. The second clasp member includes an inner tubular member slidably mounted in an outer tubular member. A lock member receiver is formed on the inner tubular member and, in a normal biased position of the inner tubular member, closes an aperture formed in a side wall of the outer tubular member to lockingly engage the lock member inserted through the aperture to join the first and second clasp members together. At least one and preferably a pair of diametrically opposed slots or grooves extend axially from one end of the inner tubular member and engage a pin mounted diametrically across the outer tubular member or projections formed on the outer tubular member, respectively, for guiding and limiting the sliding movement of the inner tubular member within the outer tubular member. Alternately, tabs are formed in the inner tubular member and are deformable into the slots or grooves. An end cap is fixed to an end of the inner tubular member normally extending outward from one end of the outer tubular member. Depression of the end cap causes sliding movement of the inner tubular member in one direction resulting in the lock member receiver opening the aperture in the outer tubular member to enable the lock member to be separated from the outer tubular member or, alternately, to be inserted into the outer tubular member.

A clasp includes releasably interconnectable first and second clasp members. The first clasp member has a hollow, cylindrical shape with first and second ends and a side wall. The second clasp member includes a hollow, cylindrical outer tubular member with opposed first and second ends. A first inner tubular member is slidably disposed within the first end of the outer tubular member. A second inner tubular member is mounted in the second end of the outer tubular member. A biasing spring mounted within the outer tubular member normally biases the first inner tubular member to a longitudinally outward position with respect to the first end of the outer tubular member. In one embodiment, the second inner tubular member is fixedly mounted within the second end of the outer tubular member. In another embodiment, the second inner tubular member is slidably mounted within the outer tubular member. Lock members are mounted on the first and second inner tubular members and releasably engage complimentarily-shaped lock receiving members formed on the first and second end walls of the first clasp member for releasably locking the first and second clasp members together.
