Patent EP-0538055-A1 (EP)
Inventor: YOUNES ABD EL RASOUL MOHAMED
IPC: F16K31/26
Filed: 1992-10-16
Abstract: There is disclosed a level control valve arrangement preferably for use in a water closet cistern for controlling the liquid level in the cistern or container. The arrangement has a liquid inlet (3) feeding an inlet chamber (1) and a movable valve member (7,10) mounted on a seating (11,12) and movable between an open position in which liquid flows from the inlet into the cistern and a closed position in which liquid is prevented from flowing into the cistern. The movable valve member is biased preferably by a float arm into the closed position in response to liquid in the cistern rising to a predetermined level. The movable valve member (7,10) is mounted in the inlet chamber into which water is fed from the inlet (3) and in the closed position the valve is acted upon by a head of water in the inlet chamber to maintain the movable valve member in the closed position. 
     The control system is distinguished by the use of water head pressure upon an upper conical surface of the movable valve member during closure thereof thereby increasing the compactness area upon its base. When releasing the movable valve member the conical form of the valve member exceeds the water pressure on the movable member during closure and slackens the pressure on it during opening. 
     Advantageously, such an arrangement ensures there is no leakage of water into the cistern, the inlet valve is not affected by changes in water pressure of the inlet supply, and the contact area of the valve is substantially increased providing a considerably reduction of wear of the valve, particularly the rubber washer between the movable valve member and seating of the inlet chamber. 
     Conveniently, the speed of water exiting from the expulsion valve opening is increased to more quickly and easily clean a lavatory for example.

Abstract: A method and apparatus for supporting multiple DMA channels by splitting data transfers for each channel into sequences of data slices and interleaving on a slice-by-slice basis. While the control of transfer resources may be shifted among the DMA channels, the ordering of the data slices for each channel is preserved. The present invention also discloses a circuit architecture capable of supporting the multiple interleaving DMA channels. The circuit architecture comprises a dual-port memory, channel sequencer, and channel interleave control. The dual-port memory stores slices of data to be transferred through the channels. A channel sequencer maintains the channel ordering of data slices in the dual-port memory. A channel interleave control unit allows channels to interleave their data transfers by monitoring the channel interleave size, current data transfer count and total transfer count per channel. A second channel is allowed to transfer data through the same medium as a first channel either when the first channel has reached its channel interleave size, or when the first channel has transferred its requested total transfer count, thus providing efficient bus utilization.

Title: Current leakage control for electrosurgical generator.
Inventor: MCELHENNEY JAY J
IPC: A61B/
Filed: 1991-09-24
Abstract: A current leakage control circuit regulates the output power of an electrosurgical generator to limit the amount of leakage current. The leakage current is monitored with a differential transformer which has the output and return leads of the electrosurgical generator as first and second windings. A third or sense winding produces a control signal whenever the currents in the output and return leads are not equal, thus indicating current leakage. The control signal is compared to a predetermined maximum safe level of leakage current. If this predetermined level is exceeded, a power control feedback loop of the electrosurgical generator reduces the output power to a sufficiently lower level to reduce the leakage current within a maximum acceptable limit.

Date Nov. 12, 1992.A centrifugal extractor comprising several superimposed stages (E1, E2, E3) has a fixed casing (10) within which rotate at high speed bowls (22) driven by a common vertical shaft (18). An immiscible light liquid and heavy liquid are emulsified and injected into a separating compartment (32) defined by each of the bowls (22) by ducts (54) forming ejectors and which are formed in the lower wall of the corresponding bowl. The light phase passes upwardly from one stage to the next by annular passages (46) surrounding the shaft (18), while the heavy phase redascends by gravity in return channels (44) formed in the fixed casing. This avoids turbulence in the separating compartments (32) and there is a reduction of the risks of clogging as a result of solid particles being present in the heavy phase.

Abstract: A device for controlling braking force of a motorcycle in two controlling modes: a normal mode and an antilocking mode, comprises tachometers mounted on front and rear wheels of the motorcycle, an accelerometer mounted on the motorcycle body, and a control circuit. The control circuit calculates a periphral acceleration of each wheel based on the peripheral velocity of each wheel, and a slippage ratio of each wheel based on the peripheral velocity of the wheel and the acceleration of the motorcycle body. When the slippage ratio and the periphral acceleration of one wheel meets given conditions, the control circuit starts, prior to entering into the antilocking mode from the normal mode, to calculate the coefficient of friction between the road surface and the one wheel. For the other wheel, the coefficient of friction is calculated in the same manner.

Abstract: The invention relates to a measuring device for determining the winding temperature of a multi-phase electrical machine (EM 1), in the case of which a DC current (which is independent of the operating current) is supplied from a DC voltage source into at least one phase (U), which is selected as the measurement phase. The direct current is then measured independently of the alternating variables occurring in the measurement phase (U) to be monitored. This results in the measurement being improved since the alternating currents and/or the AC voltages in all the phases (U, V and W) are added such that they in each case supplement one another to produce zero. <IMAGE>

Abstract: In a radio communication apparatus which uses a common carrier frequency for transmission and reception operations selectively carried out in the apparatus, a frequency divider is located between a modulator operated by a predetermined modulation frequency and a modulating local oscillator which oscillates a modulating frequency equal to an integral multiple N of the predetermined modulation frequency. The frequency divider (40) has a frequency division factor equal to N and supplies a frequency divided signal of the predetermined modulation frequency to the modulator (17) during the transmission operation under control of a control circuit. During the reception operation, the frequency divider (40) is put into an inactive state by the control circuit to isolate the modulating local oscillator and the modulator.
