  • Patent number: 6831125
    Abstract: The invention is directed to resin coating, adhesive, and cement compositions comprising styrenic copolymers and a terpene solvent. The compositions are particulary useful for toy article applications because of the use of safe, naturally occuring terpene solvents. These compositions form high adhesion bonding with molded elastomeric styrene copolymer surface substrates. The invention is also directed to a method of applying the instant coatings to substrate surfaces.

  • Patent number: 6156842
    Abstract: The present invention pertains to structures and fabricated articles having shape/reshape behavior (and processes for their preparation) comprising;(A) from about 1 to 100 wt % (based on the combined weights of Components A and B) of at least one substantially random interpolymer having an I.sub.2 of 0.1 to about 1,000 g/10 min and an M.sub.w /M.sub.n of from about 1.5 to about 20, which comprises;(1) from about 38 to about 65 mol % of polymer units derived from;(a) at least one vinyl or vinylidene aromatic monomer, or(b) at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, or(c) a combination of at least one aromatic vinyl or vinylidene monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, and(2) from about 35 to about 62 mol % of polymer units derived from ethylene and/or at least one C.sub.3-20 .alpha.

  • Patent number: 5518433
    Abstract: A toy jewel ornament includes a body having one or more articulated elements which are hingedly movable upon the body to assume a closed position covering a toy jewel also supported upon the body or an open position exposing the toy jewel. In one embodiment, the ornament is configured as a pendent and resembles an Aladdin's lamp having a jewel at its center and a generally hemispherical hollow jewel cover coupled to the pendent body by an integrally molded hinge. In an alternate embodiment, the ornament is formed in a flower-like shape having a plurality of radially extending petals and is securable to the wrist of a toy figure. The petals are movable between an open bloomed position exposing the jewel and a closed bud-like position fully enclosing the jewel. The ornaments are thermally set in the closed position by manually forcing the ornament to the closed position after warming and temporarily immersing the ornament in a cold water bath.

  • Patent number: 5234370
    Abstract: A doll supports a quantity of rooted hair fabricated to provide a posable or cold setting characteristic. The posable hair is formed of an amorphous thermoplastic material preferably having a high molecular weight in a compound including plasticizers, heat stabilizers and lubricants. The material is formed to provide a combination of glass transition temperature characteristic and hardness to produce the cold setting or posable quality.

  • Patent number: 5017173
    Abstract: A torsional joint armature for poseable figure is formed of a one-piece molded plastic material fabricated from a malleable nonelastic deformable material. The armature is articulated by a plurality of molded joints each of which includes one or more torsional deformation elements to provide the appropriate bending characteristics of the armature. Certain joints are provided with additional motion limiting webs to restrict joint motion in undesired directions.

  • Patent number: 4756539
    Abstract: A foldable golf buggy having a lower frame member supported by wheels, an upper frame member pivotally mounted to said lower frame member to swing between an upright position and a folded position lying adjacent to the lower frame member, the upper frame including an attachment to which is pivotally affixed one end of an elongate buggy handle; at least one strut member pivotally affixed at one end thereof to the lower frame member and extending up to and past the attachment alongside said handle to be captured by the attachment whereby, when said handle is moved forwardly, the attachment acts as a guide following at least one strut member as the upper frame member is moved into its folded position. The golf buggy may be provided with a seat which is also foldable and allows for ease in transportation.
