Abstract: A piston/nozzle unit retainer and stop comprises inward fingers in the cylinder slots receiving the trigger trunions which drive the unit.

Abstract: This articulated trigger/cover unit for a pump dispenser is formed with retainers on proximate relatively moveable walls to hold parts in stable configuration for handling by automatic assembly equipment.

Abstract: The dispenser comprises a plunger operating in a hollow body. The body has formed adjacent its upper end with an inward and downward annular flap. Below the flap is a vent hole. The plunger stem has a tapered zone leading to a greater diameter above the tapered zone. When the plunger is in its lockdown position, the flap cooperates with the greater diameter to provide a vent seal. The flap is backed by an outward step in the diameter of the body.

Abstract: A cassette storage basket configured for mounting on a rack mounted storage system. A wire-form basket includes an open front defined by a rectangular frame, with the frame rearwardly tilted to give the basket a triangular profile. A rear wall of the basket incorporates at least one upper hook and a rearwardly extending lower abutment to tilt the bottom of the rack-mounted basket from the horizontal to protect cassettes stored in the basket during transport.

Abstract: A closure device for a library storage box combines a hanger with a locking device for the closed storage box. A hinge structure for the device provides a first hinge portion on the box, connected by a flexible hinge to a second hinge carrying the hanger at its outer end. A latch on the second hinge portion engages a complementary detent on the first hinge portion to hold the box closed and to project the hanger to an engaging position for mounting on a suitable rail.

Abstract: A storage rack for use in a wall-mounted system, the storage rack including an array or horizontally aligned, generally equally spaced, generally parallel storage rail provided on a rectangular frame. Rack support brackets are provided behind the frame so that the frame can be mounted flush with the wall with the brackets displaced from a central horizontal access of the rack, so that a serial arrangement of storage racks, a first rack can be mounted on the wall top to bottom with a second rack mounted bottom to top so that the brackets of the first rack are so displaced from the bracket of the second rack as to support the second rack, with the arrangement of parallel storage rails so positioned as to continue the linear alignment of rails from one rack to the next.
