Title: Method and device for controlling the stroke of a press machine
Inventor: NAITO KINSHIROU
IPC: B30B15/26
Filed: 1988-11-30
Abstract: The method of controlling the processing stroke of a press machine is intended to control the levels of vibration and noise produced thereby. A control pattern relating to the velocity and pressure of the ram 13 at given points on its stroke is produced, either by determination of relevant values in a test run using sections 17, 27, 29 etc or by selection of one of a plurality of predetermined control patterns, according to the workpiece to be pressed. The control pattern is input into a control section 25 which serves to control the stroke of the machine in accordance with the determined or selected control pattern. In a punching process the velocity is controlled generally so that a fast approach (VA, Fig 2) is followed by slow actual processing (VB) with a fast follow through (VC) and return (VD). For forming, e.g. drawing the control pattern includes a period of nil-velocity (VE, Fig 6A). …<IMAGE>…

Title: Pressure swing adsorption process
Inventor: GARRETT MICHAEL ERNEST
IPC: B01D53/047
Filed: 1989-11-09
Abstract: A stream of gas mixture is compressed in a compressor 4 and then passed through a bed 1 or 2 of adsorbent which adsorbs at least one component of the mixture more readily than the other components. Product gas consisting of the non-adsorbed component(s) is withdrawn through line 13. The adsorption step is followed by a step in which waste gas is removed into waste line 19 from the feed end of the adsorbed at a pressure lower than the uppermost operating pressure. During a portion only of the waste gas removal step, the waste gas is recycled along recycle lines 21 and 29, recompressed and mixed with the feed gas. Alternatively, the waste gas is directed via line 24 into waste gas reservoir 26, from which it is removed and recycled into line 29. During the rest of the waste gas removal step, waste gas is withdrawn through discharge line 27. <IMAGE>

Patent GB-2239090-A (GB)
Title: Flame detection
Inventor: BAKER PETER DONALD
IPC: F02C7/00
Filed: 1990-11-02
Abstract: The presence or absence of a flame in an engine combustion chamber 4 is detected by monitoring the level of radiation at two different wavelengths. One wavelength is between 470nm and 530nm whereas the other wavelength is about 670nm. The ratio of the level of radiation at one wavelength to that at the longer wavelength is measured. When the ratio is between about 0.1 and 1.0, this indicates the presence of a flame. When the ratio is outside this range this indicates absence of a flame and causes a signal to be supplied to an igniter control unit 13. <IMAGE>
Patent GB-2241399-A (GB)
Title: Radar measurement apparatus
Inventor: STRACHAN JOHN SCOTT
IPC: G01S17/36
Filed: 1990-11-20
Abstract: Time of transit of a propagated electric signal at lightspeed is used as a measure of distance from a transmitter (laser 32) to a receiver (photodetector 39) via a target (reflector 14). A continuous modulating signal of fixed frequency (10.700 MHz) is transmitted using a carrier provided by laser (32). The distance traversed is measured by a timer (46) which compares the phase at transmission with that at reception. The invention involves a heterodyne down-conversion technique involving two phase-locked crystal oscillators of slightly differing frequency (30, 31), both at the transmitter location, which transfer both the inputs to the timer (46) e.g. a counter to a 10.45 kHz frequency (mixers 40, 41), thereby facilitating high resolution and precision measurement by extending the time measure representing distance. <IMAGE>

Abstract: Surface inspection of objects such as band-like running material (1) of metal, paper or textile, is carried out without stopping or slowing the inspection line by detecting defects in an image of the object e.g. obtainable by a camera (2) while determining the position of the object e.g. using a rotary encoder (I). The position and severity of defects may be marked on a chart (9), and the inspected object surface image and defect data are recorded (at 10) so that at the necessary time the defect data may be reviewed to judge the level of acceptability of portions of the object. <IMAGE>

Abstract: An optical repeater having a loop-back function used in a transmission system including first and second transmission lines L1, L2, comprising a first optical amplifier 102 (202, 302, 402), a second optical amplifier 105 (205, 305, 405), connected to the second transmission line L2, a loop-back unit 101, 103, 104, 106 (211, 212, 213, 203, 241, 242, 243, 206; 311, 312, 313, 303, 341,342, 343, 306; 412, 413, 403, 442, 443, 406), and a control unit 107 (207, 307, 407). The control unit 107 (207, 307, 407) is used to control the loop-back unit to constitute the loop-back line when a loop-back instruction is detected. Therefore, optical signals are directly amplified without converting the optical signals to electrical signals, and a loop-back signal (return signal) and optical signals are not mixed in the optical repeater, and thus a loop-back operation can be correctly carried out in an optical repeater having a small size and a low power consumption. <IMAGE>
