Patent EP-0092341-A2 (EP)
Inventor: MCMAHAN MICHAEL EDDIE
IPC: E21B34/12
Filed: 1983-04-06
Abstract: A recloseable auxiliary valve (54), for use in oil wells and the like, includes a cylindrical housing (66) having a central flow passage (68) disposed therethrough. A flapper valve (100) is disposed in the housing and is movable between a closed position wherein the central flow passage is closed and an open position wherein the central flow passage is open. An operating mandrel (106) is provided for operating the flapper valve upon telescoping movement of the mandrel relative to the housing. A releasable locking system (148, 150) is provided for locking the mandrel and the flapper valve in their open position. A time-delay system (162) is provided to prevent premature telescopic collapsing movement of the mandrel relative to the housing as the auxiliary valve is run into a well.

IPC: A61L9/03
Filed: 1983-08-22
Abstract: An aroma-generating unit adapted to periodically discharge into the atmosphere bursts of aromatic vapor, the non-aromatic intervals between the bursts having a duration sufficient to avoid desensitizing the olfactory response of those exposed to the unit. The unit includes a hollow case whose upper wall has a vent therein and whose side wall has a slot to receive a replaceable cartridge provided with a porous mat impregnated with an aromatic liquid. When fully inserted the cartridge is disposed below the vent and serves to define an air-confined chamber within the case. Disposed in this chamber is an electrical heater that is periodically energized by power pulses to heat and expand the confined air and to produce a positive pressure in the chamber forcing the heated air through the impregnated mat to rapidly volatilize the liquid and to produce bursts of aroma which are discharged into the atmosphere through the vent, which bursts are separated by relatively long, non-aromatic intervals.

Abstract: @ A high speed, integrated circuit microprocessor includes a microinstruction sequencer for sequentially generating a plurality of N control words per period, each control word having a plurality of M bits. The microsequencer includes a storage register in the integrated circuit, having a plurality of M times N storage locations, for storing a microinstruction containing the N control words. The microsequencer also includes an N bit shift register in the integrated circuit, having N sequential outputs and a clock input with a cycle time equal to 1/N of the period, for propagating a binary bit therethrough to sequentially provide an enabling bit to each of the respective N outputs thereof. A plurality of M logic stages is also included in the integrated circuit, each stage including a plurality of N AND gates, and each of the AND gates having a first and a second input, an i'" one of the N AND gates in each stage having a first input connected to an i'h one of the N outputs of the shift register and a second input connected to a respective one of the M control bits in a respective one of the N control words of the microinstruction stored in the storage register. In operation, by propagating a binary bit along the N bit shift register at the faster clock rate corresponding of 1/N of the period, the plurality of N of the control words can be sequentially output during the period. The circuit finds particular advantage in accelerating the rate at which control words can be sequentially output to a high speed processor from a control storage in the integrated circuit, having a relatively slower access time corresponding to the longer period.

IPC: E21B17/02
Filed: 1984-03-29
Abstract: A pressure regulating device for fluidtight, fluid-filled apparatus comprises a solid body with a shallow recess 4 in a surface enclosed by a flexible diaphragm 6. A narrow passage 5, preferably of capillary dimensions, connects the recess to the interior of the apparatus and the diaphragm is flexible enough to be deformed without injury so as to enter the recess and reduce its volume substantially and preferably practically to zero. The recess contains a volume of air which for optimum performance should be equal to the amount by which the volume can be reduced by movement of the diaphragm and also equal to the volume expansion of the fluid (or if more than one device is fitted its share of the fluid) from atmospheric conditions to mean working temperature (less the volume of any air occluded elsewhere in the apparatus). By this means, the diaphragm is substantially unstressed both under atmospheric conditions and under mean working conditions, since the gas will be compressed to a negligible volume.

Abstract: A semiconductor memory comprises memory cells, word lines (W+, W-), bit lines (BL, BL) and word line discharge circuits (To, DS) which co-operate with a word line discharge current controller (CTL). The word line discharge current controller is operative to gradually reduce a word line discharge current passing from a word line W- to a word line discharge circuit together with a gradual attenuation of an inverse current from the bit line to the corresponding memory cell. Such control of the discharge current can serve to reduce the likelihood of double-selection problems.

Abstract: An apparatus for and a method of extracting reinforcements from reinforced cable is described. The apparatus comprises gears between which the reinforcement is engaged and pulled from the remaining cable, the gears also serving to impart a deformation to the reinforcement. A subsequent engagement between gears imparts further deformation sufficient to cause fracture of the reinforcement. 
     A tool attachment for the apparatus comprises an elongate member having a passage for the reinforcement and a tapered end portion which causes the outer strands of a centrally reinforced cable to spread as they are pulled overthe end portion. The tool is preferably used in combination with a cutter which cuts the strands afterthey have been pulled over the end portion. A blade may also be attached to the tool to co-operate with the cutter.
