The rod end includes a keyed torque fitting having a radially extending flat with the housing including a recess holding a spring which extends radially inwardly for engaging the flat of the torque fitting when the rod is inserted into the housing for holding the rod end in the housing.
Abstract: A birdbath assembly is disclosed for controlled, automatic filling, self-cleaning and emptying with water pressure. The assembly includes a spray nozzle mounted for sliding movement through the inside surface of a bowl in response to water pressure. A series of solenoid operated fluid valves are sequentially opened by a preset electrical timing control to provide low water flow to fill the bowl, a subsequent greater water flow to raise the nozzle, agitate the water and any effluents in the bowl, and remove/expel the water and effluents from the bowl, followed by further low water flow to refill the bowl for reuse. A kit for converting conventional birdbaths to the present self-cleaning and filling invention is also disclosed.
Abstract: The specification discloses a system and method for producing a particulate MBOCA product including relatively uniformly sized granules. The system includes a pan granulator, a dust hood enclosing the granulator pan, and a blower for circulating an air stream through the hood to carry away the heat of fusion of the granulation. In a second aspect, the system includes a novel drum charging apparatus having a filler tube extendable into a drum, a dust cup covering the drum opening when the filler tube is inserted therein, and a vacuum for drawing air through the dust cup. Air displaced from the drum and product particles dispersed therein are therefore drawn into the vacuum for subsequent recovery of product particles.
