  • Patent number: 5042773
    Abstract: A merchandise display device for supporting merchanise, advertising materials or the like, having a one-piece deformable body with a support portion for engagement with a support member, such as a paint can, and a display portion for supporting the merchandise, advertising materials or other display items. A fastener clip is also provided for securing the body member in a folded display position, and for maintaining the support member and display items in clamping engagement with the body member. The support and display portions are formed by juxtaposed first and second halves of the body member, when the body member is folded together and the clip or clips are engaged with free halves of the body member in display position. The first and second halves of the body member are substantially mirror images of one another. A central axis divides the first and second halves and intersects a mid-point at the fold in the body member in the display position.

  • Patent number: 5004828
    Abstract: This invention relates to novel hydroxy-functional polyester diluents, and more particularly, to acrylic-modified hydroxy-functional polyester reactive diluents useful for blending with a variety of thermosetting or thermoplastic film-forming polymers. More specifically, the hydroxy-functional polyester reactive diluents are essentially low molecular weight polyesters derived from triols, and a combination of unsaturated monocarboxylic acids and saturated monocarboxylic acids. These hydroxy-functional polyester diluents may be compolymerized with one or more acrylic monomers, i.e. hydroxy-functional acrylic monomers, and blended with a variety of thermosetting or thermoplastic film-forming polymers. These blends of the film-forming polymers and the hydroxy-functional polyester diluents can be crosslinked with conventional crosslinking agents as isocyanates and used in the formulation of low VOC paint compositions particularly useful as automotive topcoats.

  • Patent number: 4938260
    Abstract: An aerosol can containing a liquid propellant is placed on a can support platform (44). An operator actuated fluid control switch (84) provides pneumatic fluid or compressed air to a pneumatic cylinder (46) which continuously biases the aerosol can upward into engagement with a reservoir outlet (66) of a liquid reservoir (60). A sensing switch (52) senses movement of the can support, hence, the aerosol can. An operator actuated start valve (92) enables compressed air to be supplied cyclically (78a, 78b, 96) to a pump pneumatic cylinder (70). A pump (74) driven by the cylinder cycles a preselected number of times as counted by counter (90) to pump a preselected amount of liquid from the reservoir through the reservoir outlet and into the aerosol can.
