Abstract: A faucet strainer for preventing debris carried by a dispensed fluid from clogging or jamming the faucet assembly. The faucet strainer includes a strainer body and a debris receptacle. The strainer body includes a straining mechanism which allows fluid to pass therethrough but prevents debris carried by the fluid from passing therethrough. The debris receptacle, which is disposed along a fluid dispensing flow path downstream of the straining mechanism, collects the fluid carried debris prevented from passing through the straining mechanism.

Abstract: A fluid valve structure which combines anti-siphon and anti-backflow features in a single element. The valve utilizes an insert which separates the valve body into two distinct and non-communicating chambers, permits the flow of air through one of the chambers and fluid through the other and fixes a flexible flapper-type diaphragm over the entry passages into the chambers. Due to the flexibility of the diaphragm and the independence of the chambers, that portion of the diaphragm in each chamber operates independently of the other in response to varying conditions of pressure and flow.

Abstract: A waste water valve which includes a valve housing having two inlets and an outlet. A valve plug which includes two spaced passageways is rotatably positioned within the valve housing and selectively provides a path for waste water flow through one of the inlets to the other with the other inlet being sealed during such flow.

Abstract: A modular heating cable assembly having two cold wires extending the length thereof and a resistance heating wire interconnecting the two wires. The portion of the two wires anterior to the heating wire forms a cold lead, and an element for interrupting the circuit to the heating wire is disposed in one of the wires of the cold lead. The assembly may consist of a cold lead module and one or more heating cable modules, and the element for interrupting the current may be disposed either in the cold lead or in a separate unit disposed between the cold lead module and the heating module.

Abstract: A machine safety guard for stopping a machine during any phase of operation to prevent injury to workers in which a guard lever is disposed between the worker and the hazardous area of the machine and is connected on one end to a pivot shaft. An activating arm extends from the shaft and has a post for operating a microswitch which is connected to the emergency circuit of the machine. When the guard lever is touched the lever pivots on the shaft, thereby lowering the post from the microswitch, causing the emergency circuit to stop the machine. A counterweight is used to control the sensitivity of the guard lever.

Abstract: A guard apparatus for production machines having hazardous work areas in which injury to the machine operator can occur, in which a guard rod is disposed around the perimeter of the hazardous work area and is attached on one end to an emergency circuit activation mechanism connected by an electric circuit to the emergency stop circuitry of the machine. If the guard rod is deflected either upwardly or downwardly, a switch in the activation mechanism is tripped, causing the emergency circuitry of the machine to go into an emergency off condition, thereby stopping the machine. A second emergency circuit activation mechanism can be connected to the other end of the guard rod to provide a back-up for the operation of the guard apparatus if the first switch fails.

Abstract: A valve plate for attachment to a faucet assembly which interfits with the assembly to prevent the rotation and consequent breakage of the valve housings.

Abstract: A novelty greeting card having front and rear panels hingedly connected by a spine section of finite width. A block having a thickness equal to the width of the spine and the same area as the back panel is secured to the front face of the back panel. A well formed in the central portion of the block and contains a dog biscuit.
