Title: Cooling hot metal particularly in continuous casting
IPC: B22D11/124
Filed: 1970-05-27
Abstract: 1318394 Continuous casting CONCAST AG 27 May 1970 [30 May 1969] 25577/70 Addition to 1112017 Heading B3F Moving metal, at least partly solidified, e.g. a continuous casting 3, is cooled with the aid of a cooling element, such as the element 1 shown in Fig. 1 or one of the two shown in Fig. 4, liquid coolant (water) being passed into a gap 9 between the metal and a (copper) plate 4 or 40 (or 40<SP>1</SP>) of the element through openings 8 or 43, to create a turbulent flow so that the coolant penetrates coolant-vapour film on the metal, the metal being contacted by surfaces 6 or 41 at the plate face which guide the moving metal and determine the gap width. The plates are cooled independently of the gap coolant, the plate 4 by spray nozzles 7 and the plates 40, 40<SP>1</SP> by a circulating system passing water through jackets behind them. The elements 1 or 41 are used in continuous casting installations described in Specification 1,112,017. The casting- contacting surfaces 6 are the coated ends of screws 5 arranged in staggered rows and settable to determine the gap 9, possibly differently at, say, the casting edge or to contact a curved casting surface. They may be strip-like or ring-shaped or be ribs running round the plate 1. They may be bosses or ribs created by welded or sprayed hard-facing. The adjustable screws may have flats, Fig. 3 (not shown), at their sides downstream of the casting movement to provide the openings for coolant liquid flow to the gap 9 from a jacket at the back of the plate 4. Fig. 4 shows consecutive transverse plates 40, 40<SP>1</SP>, which may comprise lengths with open expansion joints 47 between. The casting- contacting surfaces 41 are ribs and the coolant openings 43 lie between them but the surfaces may be interrupted so that a checkered pattern is formed.

Title: Improvements in and relating to spring struts for aircraft
IPC: B64C25/60
Filed: 1938-09-01
Abstract: 531,168. Hydraulic shock-absorbers. ELEKTRON CO., GES. Sept. 1, 1938, No. 25579. Convention date, Oct. 25, 1937. [Class 108 (iii)] In a spring strut for aircraft comprising two telescopic tubes, provided with fluid damping means and mechanical springing means, only the annular space between the tubes and the members guiding one tube within the other contains the damping fluid, and a throttle device, including an annular piston and additional throttling parts and having a different action for inward and outward movements, is provided within the space. In one form, Fig. 1, the strut comprises helical springs 3, 4 guided by outer and inner tubes 1, 2, the tube 2 sliding in guides 5, 6, fixed to the tube 1, and forming between them and the wall of the outer tube an annular space 7 which is filled with damping liquid. The tube 2 carries rings 9, 10, Fig. 4, between which is provided a floating piston 8 apertured at 20 and having considerable clearance within the tube 2. The ring 10 is provided with sector shaped recesses 22 so that when the strut is compressed and the piston 8 bears against the ring 10, fluid flows through the apertures 20 and the clearance space 21. The ring 9 is not recessed, so that, when the strut extends, fluid flows through the apertures 20 only. In another form, Fig. 2, the annular space is divided into a working space 7 and storage space 12 separated by partitions 14 having passages 15 controlled by an intermediate ring 13, the arrangement being such that fluid can flow from the space 12 only during extension of the strut. The piston 8 carries a throttle device, in the form of a valve plate 16, having a different action for inward and outward movement. The guiding and packing members for the tube 2 may be adapted to be inserted from one end in the tube 1 and secured by screw means at the end of the tube, the members being supported from each other by a distance tube.

Filed: 1924-11-01
Abstract: 246,588. British Thomson-Houston Co., Ltd., Salisbury, A. G., and Graham, D. H. Nov. 1, 1924. Driving.-Relates to gramophones of the kind in which the spring is wound by an electromotor, and consists in providing a centrifugal switch, adapted to open the motor circuit when the motor has been slowed down to a predetermined speed by the increase in tension of the spring. In the arrangement shown, a series-wound motor 3 winds the driving spring of the gramophone trough worm gearing 4. A press-button switch 7 and ,a centrifugal switch 5 on the motor shaft 6 are included in the circuit, Fig. 2, the two switches being in parallel. The motor is started by closing the switch 7, which may be opened when the centrifugal switch 5 subsequently closes.

[Also in Group XVI] Wafer sandwiches are made by feeding a coated wafer from a conveyer 3 on to edge supports 4 feeding a plain wafer from a conveyer 9 on to edge supports 10 above, pivoting down the edge supports 10 to drop the wafer on to the coated wafer, then pivoting down the edge supports 4 to drop the combined wafers on to edge supports 8 which then pivot down to drop the sandwich on to a carry away conveyer 2, all in timed relation by feelers and stops. There may be more than one coated wafer, finally covered by a plain wafer. Air jets 12 help to blow down the plain wafer. The shelf device may be enclosed and heated or parts only may be heated by electric heating or hot air may be passed through. Excess filling may pass through slots in the edge supports. When a wafer hits a stop plate 5, Fig. 3, it operates a microswitch 7 to hinge down the edge supports. A stop plate 15 prevents rebound back of the wafer. A shock absorber linked to 5 prevents breaking of the wafer, the shock absorber comprising a dashpot. The edge supports are hinged down and then up by air cylinders controlled by solenoid operated air valves. The micro-switch 7 may trigger a thyratron single stroke multivibrator or flip-flop 21, Fig. 5, whereupon air valve 22 is energized to admit air into cylinder 23 causing the side supports to retract. After a time air valve 22 is closed and the side supports pivot up to receiving position. Each time 21 is operated two signals are fed in to the storage circuit 24. Dekatron type multicathode counting valve, to initiate further operations according to the number of wafers entering the laminator, e.g. Fig. 6, for three superposed coated wafers and one superposed top plain wafer. A pulse 31, Fig. 6, from circuit 21 is fed to storage circuit 24. A further pulse is also fed to 24 as the supports 4 pivot up. The storage circuit 24 may be pre-set by a rotary switch to produce any number of coated layer sandwiches. The conveyer 9 may be driven by a clutch 20 closed in desired timed relation and it may be stopped by a beam of light 18 on a photo-electric cell 16. Another light beam through a broken wafer may be used to stop the machine. Specification 793,732, [Group XVI], is referred to.
