Abstract: A piston having a cup seal retainer assembly wherein the cup seal is secured between an underside of a circumferential flange of the piston and a retainer ring that is secured to the underside of the piston.

Abstract: A combination handle/bracket member is provided for use with a device, such as a suction pump, that is operated in conjunction with a separate component, such as a collection jar. The member is preferably a single-piece member with a 90.degree. bend separating a manual grasping area from a component receiving area. Also preferably the member is secured to the device with fasteners that are already used to secure portions of the device together so that no additional fasteners are required.

Abstract: A wear shield attached to a piston in a piston type compressor cushioning impact and reducing friction between the piston and a valve which opens in a direction toward the piston. During some conditions of operation, without the wear shield, a piston can impact the opening valve, which opens interior of a cylinder which holds the piston. The wear shield installed between the piston and the opening valve reduces wear on the piston and on the valve, and also reduces operating noise.

Abstract: A diaphragm compressor composed of non-metallic parts capable of being manufactured and assembled so inexpensively as to be suitable for one-time use. Conventional expensive fasteners such as screws are eliminated and assembled parts are joined by press fitting, sonic welding or similar inexpensive functionally similar means.

Abstract: A combination skid resistant and vibration dampening device formed from rubber-like material having a high coefficient of friction which is integrally bonded to cellular foam type material which has high impact absorption capacity.

Abstract: The aspirator system of this invention is directed to an economical regulator assembly which can provide a substantially uniform vacuum without the need for periodic adjustment. The vacuum of the system can be easily and accurately adjusted, thereby accommodating changes in system pressure demands. The system is not prone to vacuum leakage or undesired vacuum fluctuations.

Abstract: A toilet trip lever assembly which is mountable in a hole in a sidewall of a toilet tank is disclosed. A bearing extends through the hole and has an axial bore therethrough. Retaining means is affixed to the bearing inside the toilet tank to limit the outward movement of the bearing relative to the hole. A stem is journaled within the bearing and has an end which extends into the toilet tank and includes an offset surface. A handle is connected to the outer end of the stem and is operable by a user to rotate the stem. A boom is mounted to pivot in a plane perpendicular to the tank side wall about a pivot post which extends radially from the retaining means. An arm extends from the boom onto the offset surface and an end of the boom is connected to a flush valve. Rotation of the stem and offset surface pivots the boom to flush the toilet.

Abstract: A handle assembly for attaching a decorative handle to a turning stem is disclosed. The handle can be placed on, as well as removed from the stem by a straight axial motion (without turning the handle). In one embodiment, the stem adapter is secured to a valve stem and has an angled shoulder surface and an undercut portion. An attachment screw is employed to secure the stem adapter to the valve stem. The handle adapter has a multiplicity of resilient finger members with terminal portions adapted to engage both the angled shoulder surface and the undercut portion of the stem adapter. A handle member of a generally U-shaped configuration has a retainer member secured therein with the retainer member having finger engaging portions.

Abstract: A diverter valve for a fluid storage tank such as the storage tank of a water closet is disclosed. In one embodiment, the diverter valve has a housing with an inlet passage for receiving a supply of water and a pair of outlet passages. One of the outlet passages delivers pressurized water from the diverter valve to the storage tank, and the other outlet passage delivers the pressurized water to a diversion conduit connected to the toilet bowl rim. The diverter valve also includes a movable flap mounted within the diverter valve which moves to proportion the flow of water between the two outlet passages in response to changes in the water level of the tank. The flap is initially positioned to direct water to the tank when the tank water level is high. The flap is then moved by a water level sensor such as a float to direct water to the bowl rim when the water level in the storage tank has dropped below a pre-determined diversion level. Flow to the bowl rim continues even after the tank has emptied.
