Abstract: 1297813 Electric correspondence control systems ENGLISH ELECTRIC CO Ltd 13 March 1970 [14 March 1969] 13637/69 Heading G1N The torque developed by a rotating drum 10 in frictional engagement with a tyred wheel 12 is automatically controlled in accordance with the force exerted by the wheel 12 when subjected to braking by assembly 15. The drum is driven by a D.C. motor 18 whose armature current is supplied by a generator 23 driven at constant speed by an A.C. motor 26. The force exerted by the brake 15 on the wheel 12 is measured by strain gauges 14 mounted on the supporting structure 13 to produce a torque reference signal which is amplified at 30 and compared with the armature current of motor 18 to control the armature current of generator 23 such that the torque produced by motor 18 is proportional to the torque produced by the brake 15 on the wheel. The gain of amplifier 30 is adjusted at 33 to simulate the intended brake duty. Automatic compensation for windage, friction and copper losses are obtained by measuring the speed of rotation of motor 18 and drum 10 with tachogenerator 38, modifying this signal at 37 in accordance with a predetermined function e.g. a square law, and combining the compensating signal with the measured torque signal at 27. The apparatus may be used to test a brake system, or a tyre, or an I.C. engine coupled to the tyre. The torque measuring signal may be derived from a brake assembly 15 and may be combined with a speed signal to measure brake horsepower.

An adjustable vibrating feeder 49, or a shoot (not shown) passes the clinker over a screen 7, the sub 10-15 mm. size particles, at under 600‹ C. being discharged as finished product on to belt 10, whilst the oversized particles pass into a second cooling means in the form of a water tank 26 to distintegrate due to the thermal shock. Conveyer means 27, 20, 22 pass these disintegrated particles back into the clinker falling from kiln 1, the heat from the fresh clinker drying these particles prior to their discharge through screen 7. The water vapour produced by the cooling, which is controllably drawn off, through outlets 54, 57 and cyclone separator 24, by fan 25, maintains the clinker under an inert atmosphere during the cooling. In modifications the water spraying- may be performed in a rotary cylinder (Fig. 2, not shown) and/or the second cooling means may comprise a rotary cylinder including water spraying means (Fig. 1, not shown), whilst a clinker crusher (18, Fig. 1) may be located downstream of the second cooling means. In an alternative embodiment (Fig. 3, not shown) the clinker from the kiln is first screened, then the smaller size particles are spray cooled to 600‹ C. prior to discharge, whilst the larger particles are thermally fractured in a water tank or spray cooler before being recirculated.

Abstract: 1302141 X-ray apparatus DENTAL CORP OF AMERICA 25 May 1971 16794/71 Heading H5R Panoramic radiographs of the dental arches are produced by directing a beam of X-rays successively at different angles towards the open end of the dental arches to obtain adjacent and slightly overlapping exposures, on a single film, of the posterior left (PL), anterior left (AL), anterior right (AR), and posterior right (PR) portions of the arches while the patient remains stationary, using apparatus which includes a frame incorporating a positioning plate 18 for insertion into the patients mouth; a support for an X-ray source U pivotally mounted to perform incremental movements along an arcuate path behind the patient's head to direct the X-rays along paths PR, AR, AL, and PL; and an arch-shaped cassette holder 51 mounted for incremental lateral movement in a horizontal direction, and arranged to permit successive portions of the X-ray film to be exposed to the X-rays directed along the paths PR to PL. As shown, a vertical member 11, vertically adjustable to suit the patients' height, supports at its lower end the detachable positioning plate 18, and rails 16 and 17 permitting horizontal movement of a support member 52 for the cassette holder 51. At its upper end, member 11 has a horizontal bracket 12 having a pin 21 about which the X-ray source assembly 20, 25, 32, and 30 pivots. Slide 26 permits adjustment towards and away from the patient, while slide 34 and fastening screw 35 permit the X-ray source to be lowered by an inch and tilted upwards by about 5 degrees, by reason of the inclination of the lower portion of the bar 36, when the AL and AR exposures are made, whereby interference by the bone structure of the upper palate is avoided, interference by the spinal column being similarly avoided by the angle-preferably 14 degrees-which axes AL and AR make to the longitudinal axis of the dental arches. The cassette holder 51 is provided with four X-ray impermeable shield plates 63, 65, 67, and 69 (Fig. 9, not shown), which are successively removed as the PL, AL, AR, and PR exposures are made, the end plates 63 and 69 having lips 63e and 69e to shield the ends of the cassette, which is provided with a flexible leadcoated plastics lining (Fig. 10, not shown). The indexing of the cassette holder and the X-ray source to the positions appropriate for the successive PL, AL, AR, and PR exposures is effected by the engagement of spring-urged ball detents in part-spherical depressions formed at appropriate points on the movable members, e.g. in Fig. 8, the cassette holder is indexed to the AR exposure position by the engagement of sphere 56 in recess 57; subsequent movement of member 52 to the position in which the sphere engages in recess 57<SP>1</SP> is appropriate to the AL exposure; while for the PL and PR exposures the holder is moved until it abuts the left and right side, respectively, of the patients' face.
