Title: In-mold polymerisable coating compositions containing an isocyanate compound
IPC: C09D175/16
Filed: 1981-09-04
Abstract: Fully cured molded thermoset, and preferably reinforced, resins such as polyester, polyurea-urethane, polyurea, polyurethane, polyisocyanurate, polyepoxy and polycarbonate resins can be in-mold coated to cover surface defects such as sink marks and microcracks with an improved coating composition comprising 5-94% by weight of an ethylenically unsaturated base resin of specified type and free of groups reactive with isocyanate radicals; 5- 94% by weight of an ethylenically unsaturated monomer free of groups reactive with isocyanate radicals; and 1-20% by weight of an isocyanate- containing compound or a decomposable precursor thereof. Such coatings unexpectedly have improved adherence to molded articles over those obtained from similar compositions which contain no free isocyanate. The compositions may contain minor amounts of emulsifiers, fillers, catalysts, cross- linking agents, dryers and pigments. In particular, when the coatings contain electroconductive pigments they can be painted by standard electrostatic paint techniques.

Title: Bird cage accessory
Inventor: BUCKELL KENNETH STANLEY
IPC: A01K31/12
Filed: 1983-05-27
Abstract: A bird cage accessory comprises a substantially flat platform (11) from whose bottom surface there projects two elongate bars (21, 22) which sit the platform horizontally across the curved top of a bird cage. A through-slot (13) in the central region of the platform allows the platform to straddle the handle from which the cage is hung. In use, and with the platform in position, the sides of the slot co- operate with the sides of the cage handle to resist the natural tendency of the platform to slide one way or the other from its horizontal attitude. The platform can then be used as a perch, outside the cage, by the bird. Preferably the amount by which the bars project from the bottom of the platform is adjustable. Advantageously a detachable climbing perch or mirror or other object of play fits into sockets (17) and/or projections on the top surface of the platform. Such sockets and/or projections may be formed in posts (16) which project from the bottom surface of the platform and to which the platform supporting bars are connected. <IMAGE>

Title: Master cylinder
Inventor: SEIP HERMANN
IPC: B60T11/22
Filed: 1984-03-14
Abstract: In a master cylinder for a vehicle brake system, the position for a reservoir socket (17) for the compensating fluid reservoir is shifted in the direction of the closed end of its housing (1) that is remote from an actuating rod (9) to permit the open end of the housing to be incorporated into a vacuum housing of an associated power brake booster. A passage (21) contained in the housing wall and extending in parallel to the axial bore (2) of the master cylinder connects the reservoir socket (17) to a chamber (28) which is interposed between a shoulder (6) of a step in the axial bore (2) and a plug (26) which embraces the actuating rod (9) and closes the rear end of the axial bore (2). The chamber (28) communicates via a groove (22) in the wall of the axial bore (2) with a working chamber (3) in front of the piston (7) when the piston (7) is in its rest position. The comparatively large cross-section which the groove (22) affords the pressure fluid in the piston's rest position for propagation from the chamber (28) to the working chamber (3) and in the reverse direction, enables swift venting and brake fluid exchange operations. The groove (22) may be replaced by an annular recess (43). (Fig. 3). or lead to an annular groove (49) (Fig. 5) which accommodates the seal lip at rest. Alternatively (Fig. 2) the lip is displaced from the bore by an axial rod in the rest position. <IMAGE>
