Abstract: 686,856. Transformers; supply systems for space discharge lamps. ADVANCE TRANSFORMER CO. June 5, 1950 [June 6, 1949], No. 1401.1/50. Classes 38 (ii) and 38 (iv). A transformer for operating a plurality of gaseous discharge devices and for the supply thereto of relatively high ignition voltages, comprises an elongate core 51 forming a closed magnetic circuit and having a winding 59 at one end, a first secondary winding 62 on the core next to, and loosely coupled to, the winding 59, and adapted to be connected in series with a capacitor to supply a leading current to one of the discharge devices, a second secondary winding 64 on the core next to, and loosely coupled to, the first secondary winding 62, and on the opposite end of the core to the winding 59, the second secondary winding being adapted to be connected to a second of the discharge devices to supply a lagging current thereto, both of these secondary windings being connected to the winding 59 respectively in autotransformer relationship, and further comprising a third secondary winding 63 connected in series with the first secondary winding 62 but being closely coupled to and boosting the flux of the second secondary winding 64 whilst bucking the flux of the first secondary winding 62. The loose coupling is accomplished by the provision of magnetic shunts 52, 53 between the respective windings and an approximately sinusoidal current waveform is obtained by inserting air gaps 57, 58 in these shunts. The arrangement ensures that, in the event of the extinguishment of one of the discharge devices, the core does not become saturated, thereby maintaining the sinusoidal waveform and eliminating interference with the illumination of the remaining discharge devices. The winding 59 may comprise two windings arranged as an autotransformer.

Filed: 1973-03-27
Abstract: 1429535 Towel dispensers GEORGIAPACIFIC CORP 27 March 1973 [29 March 1972] 14643/73 Heading B8M A towel dispenser comprises a dispensing roller 36 rotatable by towelling 40 as it is pulled from the dispenser, a main take-up roll 45 for soiled towelling, a drive roller 47 coupled to the dispensing rollers 36 for driving the take-up roll 45, an auxiliary take-up roller 44 engageable by the soiled towelling in advance of the main roll 45, motor means for selectively driving the auxiliary roller 44 and sensing means 65 responsive to the passing of the trailing end of the towelling when the supply is exhausted for operating the motor to rotate the auxiliary roller 44, thus drawing the trailing end of the towelling into the dispenser. As the towelling is drawn from a supply 35 over a pinch roller 37, it rotates the dispensing roller 36 on a support shaft 54. A spring 55 is attached between the shaft 54 and the interior of the roller 36, and since rotation of the shaft 54 is prevented by engagement of a lug 71 thereon with a hook 70, energy is stored in the spring 55. When the end of the towelling passes over the roller 37, the sensing means 65, previously in engagement with the towelling, drops into a reduced diameter portion 66 of the roller 37, allowing an arm 63 bearing the means 65 to pivot about the axis of a rod 64 to which it is fixed. The hook 70, also fixed to the rod 64, thus drops from engagement with the lug 71, allowing the spring 55 to rotate the shaft 54. A chain drive connection 74 from the shaft 54 thus rotates the auxiliary take-up roller 44, which co-operates with fingers 75 to draw the end of the towelling into a casing portion 32. Alternatively, Fig. 9, and Fig. 10 (not shown), the motor means comprises a spiral spring (174) mounted between a shaft 182 drivingly connected to the take-up drive roller 152 and a housing 170 drivingly connected to the auxiliary take-up roller 138. The housing 172 is normally locked against rotation by a tab 210, held in locking position by a lever arm 226, so that rotation of the shaft 182 stores energy in the spring (174), the arm 226 being pivotable to release the tab 210 when a finger 229 is able to enter the reduced diameter portion of the pinch roller 122, so that the spring (174) drives the take-up roller 138.

Abstract: 402,096. Casting-machines. JONES, E. F., and MAUSS, W., Victoria Station House, Victoria Street, London. May 24, 1932, No. 14723. [Class 83 (i).] Moulds; castings, extracting; cores.- A machine for producing hollow ingots as described in Specification 381,790 has fluid operated means for moving the plunger and collar and may have a number of moulds carried successively into position to be operated on by a conveyer. The moulds 3 are hinged to table 2 and provided with plugs 6 to assist ejection of the casting when the moulds are inverted. The table is intermittently rotated by a hydraulic motor under control of valves 36 and a cam drum 26 rotated by an electric motor 27 through variable-speed friction gearing 30. The plunger 8 is detachably secured to a hollow rod 9 and guided by a sleeve 21 having a piston 24 working in a cylinder 25. The rod 9 is detachably secured to a hollow rod 11 having a piston 12 working in a cylinder 13. Both cylinders are controlled by valves 34 moved by plungers 35 operated by hydraulic power controlled by valves 36 and the drum 26. The collar 23, which is carried by the sleeve 21, is first moved down to close the mould and locked by closing all ports leading to the cylinder 25, then the plunger 8 is moved down until the piston 12 engages the cylinder end. The collar is again moved down to consolidate the metal and locked in position. Cooling fluid is then admitted by valves, controlled by the drum, and passages A, Fig. II, 17 to the plunger 8, to cool and contract it, and is exhausted via the hollow rods 9, 11, 14 and passages 18, B, Fig. II. Fluid is then admitted, through a non-return valve 40, to the space below the piston 12 to withdraw the plunger, the collar following at once. The pressure fluid also passes by pipes 39, 49 to a cylinder 48 and moves a piston 47 and roller 46 to the left. If the plunger has not commenced to move up a flange 10 engages a lever 43 and holds a chain 42 taut so that the roller acts to pull down a valve 41 and admit high pressure fluid from 38 to pipes 39, 50 thus acting below the piston 12 and lifting the friction gear 28 thus arresting the drum 26 until the plunger 9 rises and the valve 41 is allowed to close. The piston 47 is moved back by a constant supply of low pressure fluid when the space below the piston 12 is exhausted. Coating cores.-Lubricant, such as graphite, is blown on to the plunger, when withdrawn, by nozzles 22.
