Inventor: WALLUSSEK HEINZ DIPL-ING
IPC: E21B47/12
Filed: 1986-08-27
Abstract: A choker valve assembly for a drill string is provided for transmitting information measured in an underground bore hole by sensing devices, to the surface by modulating the pressure of the flushing fluid. The valve assembly includes a housing that is non-rotatably connected within the flushing fluid flow passage by cross-pieces extending between the housing and a portion of the inner pipe wall. A drag body valve element is mounted by the housing and is axially displaceable with respect to a tapered restriction portion of the inner pipe. Drive means for displacing the valve element is located outside the housing and extends between the valve element and the pipe wall through the cross-pieces. A cap is provided on each end of the valve element. The cap facing the direction of flushing fluid flow extends beyond the perimeter of the housing and the cap facing away from the direction of flushing fluid flow is entirely within the perimeter of the housing to provide a hydrodynamically pressure-compensated choker valve assembly.

Abstract: Local area networks having a plurality of stations connected to a transmission medium in a daisy chain configuration at the nodes or endpoints experience difficulty in detecting collisions between transmitted signals from two or more stations using standard Manchester violation or lost carrier collision detection techniques. The present invention eliminates collision detection problems in this environment almost entirely by monitoring (5, 6, 7, 8, 9, 10, 17-1, 17-2) the signal level coupled from the transmission medium to each station of the daisy chain to detect the presence or absence of collisions and generating (4) a collision detection output signal when the signal level being monitored exceeds a predetermined threshold level (1, 2, 3).

Abstract: An improved current-sensing arrangement (10) and method are provided for supplying a signal (e.g. at 14) that suitably represents line current (e.g. in 12) over a wide current range. The current-sensing arrangement utilizes the signals from an iron core transformer (32) and an air core transformer (42) along with transition and scaling arrangements fe.g. 56,58,70,62,64 and 68) to provide the sensed current signal. The range of operation includes currents for which the iron core transformer exhibits saturation effects and currents for which the air core transformer does not contribute to the combined output signal. Additionally, the range of operation includes currents for which both the transformers contribute to the combined output signal. The output of the iron core transformer dominates the combined output signal for low currents, the output of the air core transformer dominates at high currents, and the transition from the domination of the iron core transformer to the air core transformer is gradual and occurs over a mid-range of current with contribution from both transformers. 
     Accordingly, the combined output signal suitably represents the sensed current over a wide current range due to the contribution of the iron core transformer at low currents where no saturation effects are present and the contribution of the air core transformer at high currents with no saturation characteristic; a smooth transition being provided over a wide current range where both transformers contribute to the output and dominant contribution being provided by the transformer that is most accurate for the particular current.

Abstract: Disclosed is a digital ultrasonic instrument for measuring the corneal thickness (often referred to as a pachymeter) and for measuring the axial length of the eye (often referred to as a biometric ruler). A number representing corneal thickness or axial length is displayed digitally on a liquid crystal display. The pachymeter incorporates a 20 MHz solid phase piezoelectric transducer, a microprocessor, a gate array, a hybrid analog receiver circuit, a liquid crystal display and four batteries. When axial length is measured, the instrument operates as a biometric ruler, a 10 MHz transducer is used and the software in the microprocessor is modified. Ultrasonic echoes generated by the transducer and various interfaces in the eye are sampled at the rate of 40 MHz which results in equal or greater sensitivity, resolution and accuracy as compared to other pachymeters and biometric rulers currently available. The 40 MHz sample rate is accomplished by use of a grey code counter and a binary counter, each of which is sampled twice after an ultrasonic echo is detected. The two grey code samples are compared to determine a valid sample period. A counter value obtained during a valid sample period is recorded in a shift register and compared to subsequent counter values corresponding to subsequent ultrasonic echoes. The apparatus for correlating ultrasonic echoes with particular counter values assures that the counter will be sampled at a point in time when the counter is stable as opposed to being in a state of transition. The apparatus allows for a counter accuracy of 25 ns.

Abstract: A sheet material is obtained by adhesion-laminating a porous polytetrafluoroethylene film on to a gas-permeable resin layer. A hydrophilic resin layer can be applied to the opposite surface of the porous polytetrafluoroethylene or between the latter and the gas-permeable layer. Such materials exhibit both waterproof and water vapour-permeable properties, resulting from the porous polytetrafluoroethylene film or hydrophilic resin layer, and are reinforced, and provided, if desired, with artificial leather ornamentation by the gas-permeable resin layer. Accordingly, gloves or other garments, manufactured using such materials, are waterproof and water vapour-permeable and are comfortable to wear since internal condensation is avoided.
