Title: Monocoque device for disassembly and hermetic storage of used hypodermic needles
IPC: A61M5/00
Filed: 1988-06-21
Granted: 1992-11-19
Abstract: A prehensile container is provided for demounting and storing used hypodermic needles and/or surgical blades pending their ultimate disposal. The same hand that holds the container can actuate the closure blade by finger force to clear an orifice for passage of a used hypodermic needle. When the end of the syringe to which the needle is affixed abuts the mouthpiece of the orifice, the finger force can be released to hold the needle between the edge of an aperture of the shutter blade and an edge of the orifice, so that the needle can be separated by withdrawal of the syringe with one hand while holding the container with the other. Another exertion of finger force will let the used needle drop into the container and a second release will restore the closed condition of the container. Internal baffles obstruct the exit of stored needles, to prevent an unauthorized person from extracting a needle from the container by opening the access orifice.

Abstract: A magnetic field enhanced vacuum single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (66 I, 67 I) (walls and gas manifold) and a cooled wafer supporting cathode (72) and a unitary wafer exchange mechanism comprising wafer lift pins (79) which extend through the pedestal (72) and a wafer clamp ring (78). The lift pins (79) and clamp ring (78) are moved vertically by a one-axis lift mechanism (140) to accept the wafer (75) from a cooperating external robot blade (76), clamp the wafer (75) to the pedestal (72) and return the wafer (75) to the blade (76). The electrode cooling combines water cooling (170, 172, 174) for the body (128) of the electrode and a thermal conductivity-enhancing gas parallel-bowed interface between the wafer (75) and electrode (72) for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (175, 176, 178, 180) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (811, 83) of materials such as quartz are provided for surfaces such as the clamp ring (78) and gas manifold (80). The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher (60) which provides uniformity, directionality and selectivity at high gas pressures, operates cleanly and incorporates in-situ self-cleaning capability.

Title: Process for the protection of an electrical protection object
IPC: H02H3/28
Filed: 1989-05-26
Granted: 1993-08-04
Abstract: So that internal faults (7) on high-voltage lines (4), generators (5), transformers (6) and other objects to be protected are more reliably detected even with saturated current transformers (3,8) and a tripping of protective measures such as, for example, an opening of switches (2,9) is reliably prevented in the case of external faults and short circuits (10), alternating current measurement signals (I1',I2'), which are proportional to the alternating currents (I1, I2) flowing into the object to be protected, are detected by means of the current transformers (3,8). The alternating current measurement signals are then supplied via a low-pass filter (12), a transformer (13), a channel selection device (14), an analog/digital converter (15) to a microcomputer (16) for analysis. In the case of a fault, the microcomputer (16) provides a protective tripping signal (F=1) to switches (2,9) which open and thus isolate the object to be protected (4-6) from high-voltage lines (1,11). The protective tripping occurs in dependence on a difference current I=¦I1'+I2'¦ and a holding current   <IMAGE>   for cos(I1',-I2')>0; IH is otherwise said to be equal to 0. The protective tripping occurs in accordance with a bent DELTA I/IH characteristic, a conditional tripping range being additionally provided for large  DELTA I and IH values. An unwanted protective tripping, which, for example, can originate from a switch-on current surge during the switch-on of a parallel transformer, can be prevented in dependence on an external tripping inhibit signal (V), among other things.

Granted: 1994-06-22
Abstract: An electric supply installation, primarily intended for office furniture and like applications, includes a number of power supply sockets connected in a chain. A control unit is interposed between one end of the chain and the mains supply, and a pilot conductor is separately connected from the control unit via an impedance to the earth contact at the far end of the chain. This impedance forms part of a potential divider through which a pilot current flows to establish a pilot potential on the pilot conductor, and comparator means, such as a window comparator, monitors this pilot potential and disconnects the live pole if the pilot potential falls either above or below a preset range of values. This ensures disconnection on failure of continuity either in the main earth connection or in the pilot conductor itself.
