Abstract: ABSTRACT OF THE DISCLOSURE The snap-in trigger for mounting in a trigger sprayer housing comprises a trigger which includes flexible members carrying pivotal mounting elements which mate with corresponding elements in a base, e.g., the sprayer housing. The flexible members are flexed towards each other during attachment of the trigger to the base, to allow easy mating of the pivotal mounting elements. The trigger also includes a flexible locking member which can be pivoted between a first position in which the locking member is spaced apart from the vicinity of the pivotal mounting elements, (e.g., during mating of the pivotal members while the flexible members are flexed together) and a second position in which the locking member is positioned directly between the flexible members in the vicinity of the pivotal mounting elements, preventing the flexible members from moving towards one another, and thus assuring proper mating configuration between the pivotal mounting members. The locking member also includes secondary locking means for securing it in the position between the flexible members.

Abstract: An excess heat abnormality detection and alarm system for electronic equipment includes a protection unit containing a timer for counting a predetermined period of time and for outputting a time output signal, a temperature measuring means for causing temperature sensors to measure the temperatures of the  electronic  components,   first  and  second  abnormal temperature discriminating means,  and an abnormality alarm means.  The first abnormal temperature discriminating means, operating for a predetermined period of time set in the timer means,  identifies or discriminates one of the temperatures measured by the temperature measuring means as an abnormal temperature.  The second abnormal temperature discriminating means, operating after the predetermined period of time set in the timer means, distinguishes between the two temperatures measured by the temperature measuring means.  The abnormality alarm means receives an abnormality signal from the first and second abnormal temperature discriminating means, and generates a stop signal which controls power supplied to each of the electronic components.

Abstract: A method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of a positive mold of parent metal, includes embedding the mold of parent metal within a conformable bed of filler to provide therein a cavity shaped and filled by the mold. The assembly is heated to melt the parent metal mold, e.g., an aluminum parent metal mold, and contacted with an oxidant to oxidize the molten parent metal to form a polycrystalline material which grows through the surroundings of filler, the molten metal being drawn through the growing polycrystalline material to be oxidized at the interface between the oxidant and previously formed oxidation reaction product whereby the cavity formerly filled by the mold of parent metal is eventually evacuated by the metal. There remains behind a cavity whose shape inversely replicates the original shape of the mold. The method provides ceramic composite articles having therein at least one cavity inversely replicating the shape of the mold which supplied the parent metal for oxidation.

Abstract: In the system for removing volatile impurities from ground water by the generation of under-pressure within a well shaft that is driven into the area of ground water that is contaminated, a vertical flow of the ground water within the shaft itself and in the surrounding ground is enhanced by means of a suction pump within the shaft.  The output of this pump is controllable.  In addition, purification gas is introduced through a feed channel below the ground water plane.  After rising through the ground water, the gases are drawn off above the ground water plane and passed to a multi-stage filter system that incorporates connections to the feed pipe for the gases into the shaft.  By this means, controlled by means of an air choke, at least some of the purification gas can be returned to the well shaft.            ***

Title: Double seal with lubricant gap between seals for sealed rotary drill bits
Inventor: DYSART THEODORE R
IPC: E21B10/25
Filed: 1990-09-20
Granted: 1996-08-13
Abstract: This invention relates to a rotary drill bit having a body with leg members, where each of the leg members has a projecting conical cutter receiving journal.  A conical cutter having an axially extending recess open at one end has friction reducing bearings interior to the conical cutter for rotatably mounting the cutter on the journal.  A plurality of lubricant carrying conduits interior to the leg members extending into the bearings provides lubricant for the bearings.  This invention provides an improved sealing arrangement for preventing an excessive loss of lubricant from the bearings.  The conical cutter is adapted with seal receiving grooves at its open end of the recess to receive two seals, with a circumferential seal gap located between the seals.  The outer seal is less rigid than the inner seal and when the circumferential seal gap is supplied with lubricant it bleeds past the outer seal to wash away drilling debris.  Lubricant can be supplied to the circumferential seal gap by lubricant carrying conduits which carry lubricant from separate reservoirs, or the inner seal could be a hydrodynamic seal which permits migration of some of the lubricant from the bearings into the circumferential seal gap but prevents contaminates and lubricant from the circumferential seal gap from traveling past the hydrodynamic seal back into the bearings.
