Abstract: 757,359. Dimming control systems for lamps. THORN ELECTRICAL INDUSTRIES, Ltd. Jan. 5, 1955 [Jan. 28, 1954; June 14, 1954], Nos. 2663/54 and 17471/54. Drawings to Specification. Class 38 (4). In a dimming control system for incandescent or fluorescent lamps wherein the lamps are supplied from an A.C. source through discharge valves, preferably arranged back-to-back, controlled by variation of a D.C. grid voltage which is superimposed upon an A.C. hold-off voltage, sudden changes of brightness, due to, say, coarseness of the D.C. voltage controller, are avoided by the provision of a time delay network at the output terminals of the variable D.C. voltage source. The time constants may be different for falling and rising voltages. Separate D.C. voltage sources and time constant circuits are preferably provided for each valve in the case of a back-to-back pair, the grid circuits of the two valves being inductively coupled to provide for still smoother control. Such coupling may be provided by a double wound relay having its windings connected, respectively, to the two time-constant networks and the relay functioning to disconnect the lamps from the A.C. source and to interrupt the supply of heater current when the discharge currents of the networks reach a low value.

Abstract: 1426971 Rotary heat exchangers MASSACHUSETTS INSTITUTE OF TECHNOLOGY 21 Jan 1974 [24 Jan 1973] 2807/74 Heading F4K In a gas-liquid heat exchanger 101 comprising a matrix 1 in the form of a multi-disc rotor rotated by a motor 4 so that portions thereof are continually moved from contact with one fluid to contact with the other fluid, a layer 5 of light non-detergent mineral oil is provided to coat the surface of the matrix as it passes from the liquid to the gas side of the exchanger and so prevent the liquid from being attached to the surface of the discs and evaporating into the gas. The layer of oil, which floats on the surface of the liquid, e.g. water to be cooled, in a container 6, also prevents any direct contact between the liquid and gas. The gas, e.g. cooling air, contacts the upper portion of the discs as it passes through a duct 7. The oil is continuously skimmed off and circulated through a filter 9 by a pump 9A. A series of vanes 14 are provided to remove from the gas any oil which may become entrained. In an alternative embodiment (not shown), stead of using oil, the surfaces of the rotor discs are coated with a thin coating of, e.g. Teflon (Registered Trade Mark) to prevent liquid adhering thereto. Instead of using discs, the matrix surfaces may alternatively consist of woven screens, stacked spheres or comprise triangular flow passages; the matrix can be made by metal, plastics or ceramic materials.

Abstract: 642,615. Sand-blasting. FORSTER, H. A. R. Jan. 31, 1948, No. 2912. [Class 60] A sand-blasting machine in which compressed air communicates with the space above the sand in a tank and also passes through a subsidiary pipe to an orifice at the bottom of the tank, is characterized in that the subsidiary air pipe is not directly connected to the main air pipe but opens into the upper part of the sand tank so as to receive a part of the air applied to the sand from the main air pipe. The machine comprises a fabricated metal frame 1 of welded construction, with feet 2, supporting a cabinet 3 the bottom of which communicates with a hopper 4 welded to the top of a sand tank 5, having an outlet orifice 6; air from a compressor passes through main pipe 11 into the tank 5 above the level of the sand therein; a flexible pipe 10 connects the upper part of the tank 5 with a valve housing 8 associated with the orifice 6; a rubber tube 12 leads to the blasting nozzle. The front of the cabinet is closed by a window 13 sliding between vertical guides 14, a counterbalance weight 15 being provided; the operator inserts his hands through overlapping flaps 20 of flexible material. Dust removal apparatus comprises a suction fan and a settling box 21. A needle valve 23 in the housing 8 controls the flow of air past the orifice 6, the valve being adjustable, by a knob 29, to vary the proportion of air and sand delivered. Sand collecting in the hopper 4 is passed to the tank 5 through a valve 37 suspended by a chain 44 from an arm on an actuating shaft 47 the end of which carries arms 52, 53. Arm 52 is connected by articulated rods 54 with a treadle 55; arm 53 is also connected with the treadle by a tension spring 57. The main air pipe 11 contains a needle valve 58, the lower end of the valve rod 59 being secured in the outer end of an arm 62 rigidly secured upon the shaft of the treadle 55, so that when the treadle is depressed to close the valve 37 the valve 58 is opened, and when the treadle is released to allow the valve 37 to open the valve 58 is closed. By using fine sand and a small nozzle, matt or dull surfaces can be produced on chromium or other plated small components for cameras, scientific instruments &c.

Class 80 (3) [Also in Group XXII] In a mechanism for feeding wire or rod stock to a forging or similar machine including a rotatable driven member and drive means for effecting a step-by-step movement of said member, said drive means comprises an oscillatable driving member, means connecting said driven and driving members upon movement of the latter in one direction and hydraulically operating means to render said connecting means inoperative. The drive mechanism is of the type described in Specification 662,107, the feed rollers being rotated step-by-step through a collar 19 carrying a spider 29, having notches 31 within which are mounted rollers 36. Around the spider lies a ring member 34 keyed to the shaft 26 carrying the feed roller 20, and the collar is oscillated by a link 13 pivoted to a crank a.r(m 12 on a shaft 11, the throw of the link being adjusted by an adjusting screw 15. On rotation of the spider 29 counter-clockwise as shown in Fig. 4, the rollers 36 are gripped between the ring 34 and wear plates 37 on the spider, and the ring and thereby the feed rollers rotate. Reversal of the direction of rotation of the spider causes the ring to be freed. Spring-loaded plungers 39 urge the rollers to engaging relation. In order that the ring 34 may be moved in a clockwise direction to reverse the rotation of the feed rollers, without causing driving engagement of the rollers 36 with the spider 29, the rollers may be held out of engagement with the inclined surfaces 32 of the notches by pins 47 carried on a ring 46 mounted between the collar and the spider and oscillatable by a lever 40 which may be moved about a pivot 41 by the plunger 52 of a hydraulic cylinder 51 mounted on the collar. Control of the plunger 52 is effecte by a lever 57 coupled to the cylinder by a flexible connection 59.

The barrel is actuated by a Bowden wire and returned by a clock spring, the tension of which can be adjusted by rotating the end cover of the cross tube which has a square pin fitting the inner end of the spring. The cylindrical plug D, Fig. 4, has a tapered groove cut therein and is adjustable relatively to the barrel C, a spring pin Q maintaining the parts in the adjusted position. The control means may be actuated by levers. A clip J retains the end covers of the cross tube in position.
