Inventor: GARG DIWAKAR
IPC: B23K35/38
Filed: 1993-12-15
Abstract: ABSTRACT A process for producing low-cost atmospheres suitable for annealing, brazing, and sintering ferrous and non-ferrous metals and alloys, neutral hardening low, medium, and high carbon steels, sintering ceramic powders, and sealing glass to metal from non-cryogenically produced nitrogen containing up to 5% residual oxygen is disclosed. According to the process, suitable atmospheres are produced by 1) pre-heating the non-cryogenically produced nitrogen stream containing residual oxygen to a desired temperature, 2) mixing it with more than a stoichiometric amount a hydrocarbon gas, 3) passing it through a reactor packed with a platinum group of metal catalyst to reduce the residual oxygen to very low levels and convert it to a mixture of moisture and carbon dioxide, and 4) introducing the reactor effluent stream into the heating zone of a furnace and converting in-situ a portion of both moisture and carbon dioxide with a hydrocarbon gas to a mixture of carbon monoxide and hydrogen. The key features of the disclosed process include 1) pre-heating the non-cryogenically produced nitrogen containing residual oxygen to a certain minimum temperature, 2) adding more than a stoichiometric amount of a hydrocarbon gas to the pre-heated nitrogen stream; 3) using a platinum group of metal catalyst to initiate and sustain the reaction between oxygen and the hydrocarbon gas, and 4) converting in-situ a portion of both moisture and carbon dioxide with a hydrocarbon gas to a mixture of carbon monoxide and hydrogen in the heating zone of a furnace.

Title: Self testing circuit breaker ground fault and sputtering arc trip unit
Inventor: MACKENZIE RAYMOND W
IPC: H02H3/33
Filed: 1994-09-15
Abstract: Ground fault trip units for circuit breakers are tested by a passive test circuit which includes a test conductor passing through the current transformer sensing coil(s), and a test switch which selectively connects the test conductor in a loop which simulates a neutral-to-ground fault. In a dormant oscillator ground fault test circuit, the test conductor loop passes through both sensing coils. When the neutral-to-ground detector is combined with a sputtering arc fault detector sharing a common sensing coil, testing of all the components is accomplished by adding an additional test circuit which injects pulses derived from the line conductor into the sensing coil secondary, or which alternatively, connects a capacitor charged from a DC supply across the sensing coil secondary. Either of these alternative test circuits generates the successive events needed to produce a sputtering arc trip.

Title: Electrotransport system having flexible means
Inventor: LATTIN GARY A
IPC: A61N1/30
Filed: 1993-12-30
Abstract: A device (10) for the electrically assisted delivery of a therapeutic agent is described. The device (10) has rigid zones or regions (12, 14) which are physically connected by a flexible means (16) such as a web. The flexible means (16) permits the rigid zones (12, 14) to move independently with respect to each other while remaining physically connected or coupled. In a preferred embodiment, the rigid zones are physically and electronically coupled by the flexible means. In another embodiment, the device (500) comprises one or more rigid zones, the skin side of the rigid zone having a radius of curvature (520) which approximates that of the body site to wich the divice (500) is to be attached. A method of increasing the body surface conformability of an electrotransport device (50, 150, 170) is described. The method involves the step of intentionally placing rigid subcomponents (58, 36, 37) of the device in physically separate zones (52, 54; 152, 154, 156, 158; 172, 174, 176, 178) within the device. The rigid zones (52, 54; 152, 154, 156, 158; 172, 174, 176, 178) are separate and are coupled by flexible connector means (56, 62; 160, 162). In this manner, a conformable mosaic of rigid zones which comprises the device is created.
