Abstract: A plug to be temporarily located in a blocking manner within a pipe of a sewage pipe system of a building. The plug is to be installed within the pipe system as it is constructed. The plug is mounted within a flexible, enclosing wall, sleeve. The plug is constructed to be frangible and totally dissolvable within water. A clamping device is mounted exteriorly on the sleeve directly in the area of the plug. When the plug is no longer needed, the clamping device is operated to effect breaking of the plug and then disposing of the plug through the pipe system.

Abstract: A self-contained integral accumulator assembly includes a two-part housing joined by a central partition. One housing part encloses high pressure nitrogen. The other housing part encloses a volume which is divided by a flexible bladder into an oil chamber and a precharge chamber. The partition includes a recharge passage and a recharge valve for automatically repressurizing the precharge chamber from the high pressure nitrogen when the precharge pressure falls below a predetermined pressure.

Abstract: A take-up system for drip irrigation lines consisting of a mobile frame supported on wheels or skids. A predetermined number of take-up bays are provided along the frame. Each bay includes a cable spindle which is positively driven across a clutch by a hydraulic or pneumatic motor. A disk brake is hydraulically actuated to allow the operator to control the speed of the reel. A bearing support assembly is detachably secured to the reels. Each reel bay further includes a leveler which consists of a mechanically oscillatable carriage having a guide at the bottom through which one tubing line passes. The leveler applies the line on the reel evenly as the reel rotates. Cable reels may be removed and replaced with empty reels as required. The device is also operable to control pay-out of lines when the lines are being placed in the field at the beginning of the growing season.

Abstract: A ribbon tension control for controlling the tension of ribbon traveling between a rotating supply spool and a rotating take-up spool varies the amount of braking torque applied to the supply spool to hold ribbon tension constant as the distribution of ribbon between the spools changes. A generator rotationally coupled to the supply spool produces braking torque to resist the rotation of the spool when the generator windings are electrically loaded. The loading of the generator is controlled by processing feedback signals emitted by the generator to provide periodic load switching signals. Processing of the feedback signal is accomplished in the exemplary embodiment by a drag lookup table which is addressed by the feedback signal. The drag lookup table produces a duty cycle value which is used to determine the duty cycle of the switching signal, which, in turn, controls the electrical loading of the generator.

Abstract: An extra-resilient shaft coupling. Two rigid parts are interconnected by a resilient intermediate member which transmits torque. The intermediate member includes two external metal ring members which are in the form of one or more peripheral parts and are interconnected by an elastomeric material, preferably vulcanized in situ. To avoid over-stressing the elastomeric material at the regions adjacent to the metal parts, the ring members, near the outer peripheral surface of the rubber element, are provided with an axially projecting annular shoulder which abuts an edge region of the rubber element. The inner peripheral edge of the ring members has an approximately V cross-section, the point of the V being rounded and the outer side surface being recessed relative to the outer surface of the ring member to thus form a peripheral recess for receiving a lip formed on the rubber element.

Abstract: An adjustable shower head assembly is provided which includes a minimum of parts for enabling the adjustment of a shower head to accommodate persons of varying stature. A housing including a front panel, having a slot therein, is provided along which a conventional-type shower head is adjustably mounted therealong, the position of the shower head being maintained at any preselected position along the slot by a flexible hose which is contained within the housing by interior surfaces of the housing sides. The interior surfaces, in effect, provide abutment and a guide means for restricting the shape and position of the hose within the housing. In addition, the force of water through the hose during operation of the shower head exerts sufficient pressure against the housing sides to stabilize the shower head along the slot, despite the forces generated against the shower head by exiting water.
