IPC: B01D46/24
Filed: 1976-12-21
Abstract: 1519109 Air filter ECOLAIRE INC 21 Dec 1976 [29 Dec 1975] 53361/76 Heading BIT An air filter system, e.g. for fly ash at 1,200F, comprises a housing 40 having a dirty gas inlet 38, a vent outlet 44, a valve means 46 connected to said housing by way of the vent outlet to optionally vent said housing or connect the housing to a source of pressurised gas, a hollow tube 60 of refractory material an open end of which is arranged to obturate said outlet 44, means closing the other end of the tube 62 and supporting said tube in said housing 64. Dirty gas flows upwardly, is filtered and exits through opening 48. Valve 46 may be piston operated and selectively allow pressurised gas to flow through opening 50 to backflush the element. The apparatus may be part of a larger system (Fig. 1) which accepts fly ash through valved inlet 20 and passes the ash through outlet 18 to a valved gas conveying tube 30.

Abstract: 1,123,146. Table tops. HUGHES-OWENS CO. Ltd. 30 Nov., 1966 [17 Feb., 1966], No. 53528/66. Heading A4H. [Also in Divisions B5 and B6] A drawing board structure comprises a layer 6 of expanded polystyrene, sheets F of aluminium glued to both sides of the layer 6, and a layer 11 of linoleum which is applied to the top surface to provide a drawing surface. The edges of the sheet F are secured to rigid aluminium or plywood, members 8 by rivets or bolts 9. Aluminium channel members 10 trim the outer edges of the structure, and one channel member (10a, Fig. 1) is shaped to form a pencil rack. The board is pivotally mounted for angular adjustment about a horizontal axis between a pair of legs (3, Fig. 1) of a support (2). 1,123,243. Timing device. SMITHS INDUSTRIES Ltd. 10 Feb., 1967 [15 Feb., 1966], No. 6689/66. Heading A4D. [Also in Divisions G3, H1 and H3] A timing circuit for use with heating devices such as an oven heating element and boiling rings comprises adjustable controls 1, 3, 4, 5 for setting the required temperature for each heating device, a potentiometer 35 for switching off all the heating devices at the end of a pre-set time and controls 10-13 for setting the duration of operation of each heating device. A pointer 8 is attached to a disc of the potentiometer and indicates on a clock 6 the time at which the heating devices are to be turned off. A wiper engaging the potentiometer wire on the disc is rotated by a synchronous motor at a speed of one revolution in twelve hours. Each control 10-13 comprises a potentiometer 47, the setting of which determines the instant that a transistor 41 starts to conduct and therefore the instant at which a transistor 48 ceases to conduct. When the transistor 48 ceases to conduct a transistor 68 conducts and a relay 71 switches on the heating device. At the time indicated by the pointer 8, the wiper disengages the potentiometer wire and the transistor 41 ceases to conduct so that the heating device is switched off. The transistor 68 also ceases to conduct when a transistor 58 conducts, the state of the latter being governed by the respective one of the controls 1, 3, 4, 5 each of which comprises a variable resistor 61. The resistor 61 is in series with a negative temperature coefficient resistor 55 located close to the heating device to enable the operating temperature of the heating device to be pre-set. The potentiometer is ganged to a switch 69 so that the potentiometer may be set to a position in which the switch is open thus allowing manual instead of timed operation of the heating device.

The top and bottom stiffeners adjacent the loading aperture are formed into guide rails 16, 17 respectively along which the sliding door 13 is guided. The sliding door 13 moves freely from one end of the loading aperture to the other. The sliding door 13 is provided with guide members which cooperates with the upper guide rail 16 and the lower guide Tail 17 to keep the rails parallel when they are subjected to loading stresses. In the construction shown the upper guide members comprise guide rollers 26 which run in a guideway 21 of the upper guide rail and the lower guide member comprises a guide rail 31 which forms part of two supporting runners 29 of the sliding door. An additional guide bracket may be provided to co-operate with the lower guide rail (Figs. 6, 6a, not shown). A second door 14 of the embodiment is a sliding, swivel door. Other embodiments disclosed comprise a sliding door with two sliding, swivel doors (Figs. 12, 12a, not shown), one or two sliding doors with two container corner hinged swing doors (Figs. 14, 14a and Figs. 13, 13a respectively, not shown), and one sliding door with two folding doors (Figs. 16, 15a, not shown).

This device comprises a pair of opposed push rods 44, 45 which are urged in their respective directions by a handle 46 through a lever 42. The push rod 45 has a bolt 50 which, in the locked position, enters a slot in the guide rail 17 and also bears against the running rail 27 thereof to lift the door upwardly. This upward lift brings a catch 52 welded to the door into frictional engagement with the guide rail 17 to clamp the door against transverse and vertical movement. The push rod 44 is provided with a pressure member 49 which has a wedging action with the upper guide rail 16 to urge a catch 48 of the door into frictional engagement with the upper rail to again clamp the door (Fig. 8, not shown). Part of the member 49 co-operates with a pair of stops 23a to prevent opening movement of the door. The device 40 for the sliding door 13 is as the abovementioned device 40 except that the pressure member 49 is omitted and an angled bolt is provided which, in the locked position, passes behind the guide rail between stops formed thereon.

Abstract: 1282057 Making liquid-cooled electrical conductors ALLMANNA SVENSKA ELEKTRISKA AB 4 Dec 1969 [5 Dec 1968] 59257/69 Heading B3A [Also in Divisions H1 and H2] In a directly-cooled conductor for a liquid cooled electrical winding comprising a cooling tube 3 surrounded by a conductor bar 1, the conductor bar is made with a continuous crosssection along the greater part of the total conductor length of the winding and the cooling tube is expanded to provide heat-conducting contact with the bore of the conductor bar. The cooling tube 3 is slightly longer than the conductor bar and its projecting ends are sealed in high pressure casings 5, 6, by rings 8, 9. The central cavity 2 of the bar 1 provides sufficient clearance around the tube 3 to prevent damage to the tube as it is inserted. Pressure fluid is then admitted through a conduit 12 such that plastic deformation of both bar and tube occurs and the entire surface of the cavity 2 is in contact with the tube. When the pressure is released, elastic contraction of the bar is greater than that of the tube, suitable materials being copper for the former and stainless steel for the latter. The tube may also be expanded by passing a series of mandrels of increasing diameter therethrough or by igniting an explosive charge in the tube.
