Abstract: PCT No. PCT/SE82/00323 Sec. 371 Date Jun. 2, 1983 Sec. 102(e) Date Jun. 2, 1983 PCT Filed Oct. 7, 1982 PCT Pub. No. WO83/01283 PCT Pub. Date Apr. 14, 1983.A crankshaft for combustion engines has a number of components joined to each other. Each component comprises a counterweight, a portion of a main bearing journal, and a portion of a crank bearing journal. Adjacent components are so arranged that their crank bearing journal portions are connected to each other to form a complete crank bearing journal, and their main bearing journal portions are secured to each other to form a complete main bearing journal. One of each pair of portions is longer than the other; and oil ducts extend through cavities in the components but do not communicate with those cavities. Instead, the ends of the ducts open through the journal bearing surfaces, and specifically through the longer of the two journal portions so that the opening of the ducts can be central of the journal and still not interfere with the joint between the components.

Title: Programmable logic controller
Inventor: VAUTIER REMI ALFRED MARCEL ROB
IPC: G06F13/10
Filed: 1982-12-28
Granted: 1988-10-27
Abstract: The control program is stored in a programmable read-only memory addressed by an instruction address register. When a read-out instruction is read from the PROM, a condition flip-flop is set in accordance with the state of the addressed input. During a write operation the state of the flip-flop or its inverse is written to the addressed output, also in accordance with the condition bit. A jump instruction is realised only if the flip-flop is in state 1. A random-access memory, organised in 16 eight-bit blocks selected by a block pointer, replaces one of the input multiplexers and one of the output demultiplexers, and allows past states of the inputs of the controller to be memorised and used afterwards.

IPC: G01N29/04
Filed: 1984-03-05
Granted: 1989-02-09
Abstract: A method and apparatus for processing ultrasonic echo signals employ intermediate storage and representation of the echo signals in the form of image vectors, such storage and representation proceeding independently of the scanning technique utilized to generate the image vectors, such that switching among various scanning techniques is permitted. The full length of each image vector is written into an image memory in column fashion, the stored vectors being read out as image signals in a format suitable for specific types of representation, such as on a television monitor, the format instructions being contained in a memory or generated by an arithmetic unit. Upon read out from the image memory, the geometric form of the ultrasonic scan is reconstructed in a position and form corresponding to the actual scan, and the ultrasonic echo signals are similarly represented at their true positions.

Abstract: A closed loop thermal recording system and method are provided for recording an image represented by pixel areas of varied density on a thermally sensitive recording medium. The system receives electronic image information defining a desired density for each pixel area and applies thermal energy to selected pixel areas to record in each a dot having an initial size that is smaller than necessary to achieve its desired density. The density levels provided by the initial dots are measured and compared to desired density. Based on these comparisons, additional thermal energy is applied to progressively to increase dot size until a predetermined density comparison value is achieved for each selected pixel area.

Inventor: PAVLATH GEORGE A
IPC: G02F1/01
Filed: 1986-01-16
Granted: 1991-05-08
Abstract: @ A gyroscope system includes a coherent light source that supplies counterpropagating waves to a sensing loop through a pair of directional couplers. The polarizations of the waves are controlled so that they traverse identical paths before recombining in one of the couplers to form an interference pattern. Rotation of the sensing loop, a phase modulator and a frequency shifter cause phase changes in the counter propagating waves. A detector monitors the interference pattern of the combined waves and provides a signal to the coherent demodulator that controls the phase modulator. The output of the coherent demodulator is input to a servo loop circuit that drives a voltage controlled oscillator. The output of the voltage controlled oscillator is an oscillatory signal having a frequency equal to the shift in frequency that the counter propagating waves experience in traversing the frequency shifter. The feedback circuitry adjusts the frequency shift to null the phase difference between the counterpropagating waves. The frequency shift is linearly related to the frequency of the signal output from the voltage controlled oscillator. Each cycle of the output of the voltage controlled oscillator corresponds to a fixed angular increment of displacement of the sensing loop. The rotation rate of the sensing loop is a function of the frequency shift and transit time of the waves through the sensing loop. The gyroscope system determines rotation rates and angular displacements over a wide dynamic range by measuring the frequency and zero crossings of the oscillatory output of the voltage controlled oscillator.
