IPC: A47L15/42
Filed: 1992-08-04
Granted: 1996-09-24
Abstract: A combination motor-pump and soil separator assembly includes a reversible motor which drives a wash pump and a drain pump.          When operated in a wash mode, the wash pump directs pressurized wash liquid to one or more wash arms.  In addition, a centrifugally sampled portion of the wash liquid containing a high concentration of entrained soil particles is directed to a guide chamber.  The guide chamber is in fluid communication with a soil container, which receives the wash liquid to be treated.  Soil-laden water received within the soil container is passed through fine filters disposed in a wall of the soil container, resulting in a cleansed wash liquid.  The cleansed wash liquid is then returned to the wash pump, where additional wash liquid is added, for recirculation within the dishwasher.  Upon completion of a wash cycle, the motor is operated in the opposite direction, providing a draining action within the soil collector.

Abstract: An externally threaded vessel having an outwardly pro-jecting directed pour spout (2) to permit substantially mess-free dispensing of liquid from the vessel. The tip (3) of the outwar-dly projecting directed pour spout exhibits a cross-sectional profile which resides completely within the outline which would be formed if the external thread (21) on the vessel were to be ex tended upwardly a sufficient distance to include the tip of the pour spout. Sizing and positioning the tip of the pour spout in the foregoing manner permits dispensing of liquid from the ves-sel without contaminating the external thread or the exterior surfaces of the vessel, yet permits engagement of the vessel with a secondary vessel having a complementary thread engaging means without any interference with the tip of the outwardly projecting directed pour spout. In essence, the cross-sectional profile of the tip of the outwardly projecting directed pour spout acts as an extension of the external thread on the vessel incorporating the pour spout.

Abstract: An internetworking node for providing internetworking services for mobile wireless nodes is disclosed. Each mobile wireless node is associated with at the most one internetworking node. Each mobile wireless node selects which internetworking node it will associate with. The internetworking node will then act for all wireless nodes associated to it in relaying messages between wireless nodes or between a wired lan and the wireless nodes. A tracking mechanism for such a system which maintains a table of all the internetworking nodes the wireless node has recently heard and deleting all such internetworking nodes which have not been heard recently is disclosed. A switching mechanism for such a system for determining when the wireless mobile node should switch its association from one internetworking node to another is also disclosed. The switching mechanism determines whether a particular internetworking node overheard by the mobile wireless node has been heard recently, and if not will associate with such an internetworking node. Otherwise the wireless node maintains its current association, with a particular internetworking node until a failure to communicate occurs or the said tracking mechanism deletes its reference to the said internetworking node.

Abstract: A method of manufacturing an injection molding nozzle having an integral electrical heating element. The heating element is mounted in a space formed between an inner core, an outer rear collar and an outer sleeve. The space is first sealed by brazing with a nickel alloy brazing material and a copper conductive material is then cast into the space. Both the brazing and casting are done in a single controlled cycle of a vacuum furnace. An insulative cap is placed over the assembly so a supply of inert gas to the vacuum furnace cools the copper conductive material from the bottom up. This produces unidirectional solidification to avoid the formation of voids in the copper conductive material and improve thermal conductivity.
