Patent EP-0224491-A4 (EP)
Title: Method and circuit for providing adjustable control of short circuit current through a semiconductor device.
Inventor: BYNUM BYRON G
IPC: H02H9/02
Filed: 1986-02-10
Abstract: Power Field Effect Transistors are commonly used to provide a series conduction path between a source of operating potential (12) and a load (14). A problem occurs if the load should cause the transistor to become a short circuit during which time rush currents across the FET (10) may seriously damage or even destroy the FET. A solution for limiting short circuit current flow in a Field Effect Transistor (10) and to limit the power dissipated therein includes sensing a rise in the drain-to-source voltage of the transistor and clamping the gate-to-source voltage to a predetermined adjustable value thereby reducing the magnitude of the short circuit current flow to within the safe operating characteristics of the device. A comparator switch circuit (32, 36) is responsive to the drain-to-source voltage of the FET exceeding a reference voltage value for clamping the gate-to-source voltage to a predetermined reduced voltage. A trimmable resistive network (40) is connected between the gate and the source electrode of the transistor for adjusting the gate-to-source clamped voltage potential to compensate for variations in transistor transductances from one transistor to the next that may be used in conjunction with the electronic circuitry.

Title: Casting in an exothermic reducing flame atmosphere.
Inventor: LIEBERMANN HOWARD HORST
IPC: B22D11/06
Filed: 1986-04-11
Abstract: An apparatus and method for casting metal strip include a moveable chill body (7) having a quench surface (5) thereon. A nozzle mechanism (4) deposits a stream of molten metal onto a quenching region (14) of the quench surface to form the strip (6), and a gas supply mechanism (8, 12) provides an initial gas mixture, which consists essentially of carbon monoxide and oxygen. An ignition mechanism ignites the initial gas mixture to create an exothermic reaction which provides a low density reducing flame atmosphere at a depletion region (13) located substantially adjacent to and upstream from the quenching region. A control mechanism (16) controls the initial gas mixture to produce an adjusted reducing flame atmosphere at the depletion region in which the adjusted reducing flame has a burnt gas composition that includes substantially no free oxygen.

Title: Process for the recovery of oil from waste oil sludges
Inventor: HEUER STEVEN RAY
IPC: C10G31/10
Filed: 1990-09-10
Abstract: Commercially valuable oil is recovered from refinery-produced, Resource Conservation and Recovery Act classified, hazardous waste oil sludges by a series of volatilizing and condensing steps (which may vary depending on the oil, water, and solids content of the sludge) resulting in the production of nonhazardous water and solid waste by products. A pumpable, low viscosity, high oil- and/or water-contentsludge (10) is first centrifuged (14) to separate free oil and water (16), while the thick waste oil sludge, centrifuge solids, or other sludges low in oil and/or water content are heated in a volatizer (24) to volatilize the contained water and oil. Dry, friable, deoiled solids are recycled with the oily sludge feed to prevent material agglomeration and heat exchanger fouling. Oil and water vapor from the high-temperature volatilization apparatus is recycled as an indirect heat source to the low-temperature volatilization apparatus. The volatilized oil and water are condensed and combined with the oil and water centrate, and the oil and water are essentially separated as by gravity in a settler. The separated oil is again centrifuged to remove any entrained water and solids. The nearly oil free, nonhazardous waste water and nonhazardous, deoiled solids can be disposed of in a conventional manner, and the commercially valuable recovered oil is suitable for further refinery processing.

Title: Viracidal, bactericidal and spermicidal vaginal suppository
Inventor: FORD LARRY C
IPC: A61K35/747
Filed: 1994-12-02
Abstract: A vaginal suppository or other type of vaginal passary such as cream, foam or ointment, which contains as its active ingredients at least one pharmaceutically acceptable, topically safe antimicrobial agent, such as an agent selected from the group of benzalkonium chloride, cetylpyridinium chloride, chlorhexidine gluconate and povidone iodine, imidiazolidinyl urea and diazolidinyl urea and a viable colony of micro-encapsulated lactobacilli bacteria. The viable lactobacilli are included in the suppository in micro encapsulated form, which protects the bacteria during storage of the suppository from the action of the bacteriocidal agent. When exposed to the vaginal milieu the micro encapsulation breaks down sufficiently to release the lactobacilli bacteria. The lactobacilli bacteria serve to maintain or re-establish a healthy lactobacilli based flora on the vaginal wall, and excrete hydrogen peroxide and other bactericidins which suppress abnormal flora conditions that promote infections.

Title: A fully-pipelined fixed-latency communications system with a real-time dynamic bandwidth allocation
Inventor: WINGARD DREW ERIC
IPC: G06F13/368
Filed: 1998-07-22
Abstract: The present invention provides for an on-chip communications method with fully distributed control combining a fully-pipelined, fixed-latency, synchronous bus with a two-level arbitration scheme where the first level of arbitration is a framed, time-division-multiplexing arbitration scheme and the second level is a fairly-allocated round-robin scheme implemented using a token-passing mechanism. Both the latency and the bandwidth allocation are software programmable in real-time operation of the system. The present invention also provides for a communications system where access to a shared resource is controlled by the above communications protocol. Access to and from the shared resource from the subsystem is through a bus interface module. The bus interface modules provide a level of indirection between the subsystem to be connected and the shared resource. This allows the decoupling of system performance requirements from subsystem requirements. Communication over the bus is fully memory mapped.
