Abstract: 1517571 Determining profile photoelectrically CENTRE DE RECHERCHES METALLURGIQUES - CENTRUM VOOR RESEARCH IN DE METALLURGIE 2 July 1975 [2 July 1974] 27821/75 Heading G1A Two rotating mirrors, 13, 19, Figs. 3a, 3b are used to synchronously scan a spot of light and the field of view of a detector or detectors across an object along a predetermined line to determine the object's profile; the co-ordinates of points on the object are determined from the angle of the mirrors and the position at which the beam reflected from the object strikes the detectors. Instead of the scanning spot, the object may be illuminated by a planar light beam, and the field of view of the detectors may be scanned along the intersection of that beam and the object. The planar beam may be spatially modulated. When a scanning spot is used, the detector field of view need not be scanned if the detector is a series of diodes associated with a cylindrical lens, or is a two dimensional array of diodes.

IPC: G21C7/12
Filed: 1955-09-30
Abstract: 836,975. Control of A.C. motors. REYROLLE & CO. Ltd., A. Sept. 28, 1956 [Sept. 30, 1955], No. 27950/55. Class 38 (3). [Also in Group XXXV] Control rods are moved in and out of the core of a nuclear reactor by means of electric motors 10, 11, 12 of the polyphase synchronous type. Each motor has separate windings 13A, 13B, respectively supplied from generators 14A, 14B, and each motor winding is capable of alone producing full control of the movement of the associated rods, in the event of the supply to the other winding of that motor being interrupted. Each generator has a compensating winding 19 connected in series between the fixed brushes 17 and the output terminals 20, a field winding 18 of the generator being connected through rheostats 21 to the output of an exciter. The field system of this machine comprises a rotatable frame 26 driven by pilot motor 30 through gearing 31, the field winding 27 being excited with direct-current through brushes 28 co-operating with commutator 24. The frequency of the generator output is directly proportional to the speed at which the exciter field system is rotated, and its phase sequence depends upon the direction of rotation of the field system. When the field system is held stationary the generator has a direct-current output and the motors are locked in position. The gear-boxes 31A, 31B, associated with the pilot motors 30A, 30B, and exciters 22A, 22B, for the generators 14A, 14B, are intercoupled by a synchronizing shaft 36. This ensures that the frequency, direction and phase displacement of the outputs of the generators are maintained in synchronism, so that the motor windings 13A, 13B operate in unison. The generators and their associated exciters have common driving motors 35A, 35B. Specification 836,976 is referred to.

Abstract: 1353906 Control of D.C. motors BRITISH DOMESTIC APPLIANCES Ltd 10 June 1971 [10 June 1970] 28188/70 Addition to 1266691 Heading H2J [Also in Division G3] The washing machine control circuit of the parent Specification is modified so that, in the out of balance condition, the drum speed is reduced to zero, and then accelerated again to its high (spin) speed, preferably with a period at its low (wash) speed. A transistor 75 is connected between the base of transistor 19, which controls the motor through thyristor: 2, and the negative voltage rail 69. Switch 30 momentarily closes in response to the drum becoming out of balance, burning on transistors 34 and 75, the latter reducing the voltage reference at the base of transistor 19 to zero, stopping the motor. When switch 30 opens, capacitor 52 starts to charge, and, through divider network 73, 74, turns transistor 75 off, allowing capacitor 60 to charge to apply a reference to transistor 19 to run the motor up to its low speed. As capacitor 52' continues to charge, transistor 34 is switched off allowing capacitor 24 to discharge and effect controlled acceleration of the motor up to its high speed. In another embodiment, a diode (66) Fig. 1 (not shown), which is connected between the base of transistor 19 and the collector of transistor 34, is reversed biased when transistor 34 turns on, i.e. when the drum becomes out of balance and reduces the reference to transistor 19, and thus the motor speed, to zero, until transistor 34 turns off.

Abstract: 251,190. Withers, J. S., (Marion Machine Foundry & Supply Co.). Nov. 12, 1925. Cleaning, fluid-pressure processes for.-Relates to soot-blowers of the type having a rotatable blow-tube with inlets at one end surrounded by a pressure chamber; and in which the inlet valve is fully open before, during, and after the rotation of the tube, and is operable independently of the rotation of the tube. According to the invention the blow-pipe 12 is operated by a sprocket wheel 30 carrying a pawl 40 which engages in a slot in the tube to rotate it, but which, during part of its revolution, is held out of engagement with the tube by a pin 51 which engages a camplate 50. On rotating the sprocket wheel the valve 24 is opened by means of a spur and pinion 32, 34, and steam is admitted to the inlet chamber 27. Continued rotation of the sprocket-wheel causes the pawl 40 to be lifted and the tube to remain stationary until the direction of rotation of the sprocket wheel is reversed. The cam-plate 50 is spring-pressed and is so positioned on the disc 11 that the valve 24 will be moved to the closed position and then started on its opening movement while the tube 12 is stationary to enable steam to be supplied as soon as the tube begins to rotate. The cam-plate 50 is secured by a headed nut 47 to an undercut annular groove 46 on the stationary disc 11.
