Abstract: A novel four passage intake nozzle and valve structure is provided for use with a specially designed, novel water deflection member to provide a pop-up water spray nozzle. The novel intake nozzle and valve structure includes a hollow valve plug, having a lower cylindrical portion provided with four specified longitudinally-extending passages, and an upper cylindrical portion provided with four specified, longitudinally-extending passages the upper and lower passages surrounding a central core. The upper passages are connected to associated lower passages through an associated, smaller diameter aperture. Parts in the valve plug, communicate with an associated one of the four lower passages. An apertured disc, is rotatably movably connected to the valve plug, by means of a shaft disposed within the central, hollow core, the apertured disc having ports therein, the leading edges of the ports therein being adapted to index precisely with the leading edges of selected ports of the valve plug.

Abstract: A novel four passage intake nozzle and valve structure is provided for use with a specially designed, novel water deflection member to provide a pop-up water spray nozzle. The novel intake nozzle and valve structure includes a frusto-conical plug having an upper chamber and a lower portion provided with four specified longitudinally-extending passages surrounding a central core, each passage leading to an associated individual, unconnected, peripheral, longitudinally-extending passage of a four passage cylindrical conduit. Ports are arranged around the conical face of the frusto-conical plug and at at least two locations along its axial length, to communicate with the four specified passages passages. An apertured frusto-conical sleeve, is rotatably movably connected and is disposed about the frusto-conical valve plug, by means of a shaft disposed within the central, hollow core.

Abstract: A load measuring device is provided herein which operates with a small amount of vertical travel. The load measuring device includes a base with a thin sealed fixed volume reservoir having a non-compressible fluid (e.g. oil) or soft rubber therein forming the lower portion of the base. A flexible diaphragm is provided which seals such thin reservoir and is in direct contact with the non-compressible fluid or the soft rubber in the reservoir. A platform is provided for applying a load directly to the diaphragm. Finally, a transducer including an integral diaphragm is held in direct contact with the flexible diaphragm to provide a reading which is proportional to the absolute value of the load. The invention thus provides a sealed, shockproof, hydraulic load cell whose manufacture is greatly simplified and whose cost is reduced both in terms of time and material. Moreover, its installation in a weigh scale is much simplified since there is no hydraulic connection needed between the load cell and the transducer.
