Patent GB-554799-A (GB)
Abstract: 554,799. Gas burners. RADIANT HEATING, Ltd., and DOCKING, A. Jan. 13, 1942, No. 505. [Class 75 (i)] A high pressure gas heater such as a radiant heating panel is supplied with gas by a gas compressor, the gas being replaced by air for a short interval before the compressor is stopped and air only being supplied on restarting the compressor until gas is supplied at full pressure. In the apparatus shown a compressor 3 normally supplies gas from a low-pressure main 2 to a heater pipe 1, the connecting pipe 6 between the compressor and the main being fitted with a non-return valve 11 and a dash-pot controlled slow-opening but quick-closing valve 11a which is biased to the closed position by a weight. A pipe 1a maintains a pilot burner at the heater permanently alight. A valve 10a in an air supply pipe 9 connected to the compressor inlet is normally held closed by the gas pressure on a diaphragm 14 communicated through a pipe 18 fitted with an electrically-operated valve 16. When a thermostatic device ceases to demand heat the valve 16 closes and the pressure in the diaphragm chamber 13 seeps away through a bleed-hole connected by a pipe 20 to the compressor inlet. The valve 10a then opens slowly to admit air to the compressor inlet and the valves 11, 11a close. During its opening movement the valve rod 15 operates a rod 24 to open a mercury switch 12 in the circuit of the motor 4 driving the compressor. On a fresh demand for heat the valve 16 opens and the gas pressure on the diaphragm 14 quickly closes the valve 10a. The switch 12 then closes to start the compressor and gas is supplied to the heater, the length of the pipe 1 ensuring that by the time the gas reaches the heater it is being supplied at full pressure. A small bore pipe 22 may connect the chamber 23 above the diaphragm 14 to the compressor inlet to ensure the diaphragm lifting the valve 10 to the closed position if the gas pressure in the main 2 is abnormally low. A non- return valve 211 prevents back surges reaching the valve 10.

Abstract: 1483778 Bounce crimping yarn CHEVRON RESEARCH CO 23 Dec 1974 [28 Dec 1973 (2)] 55649/74 Heading D1F A bounce crimping apparatus in which multifilament yarn 12 is hurled by steam against foraminous surface 44 and rebounds to leave by lateral exit 52 whilst the steam exits via tube 46 which is longitudinally aligned with yarn inlet 40 is characterised by orifice means 104 removably positioned within the interior of the housing 22. The orifice means includes a longitudinal passage 105, Fig. 3 coaxially positioned with respect to the longitudinal axis of housing 22, a first frustoconical surface 106 which mates with a first frustoconical ledge 112 in extension 102 of housing 22, and a second frustoconical surface 108 positioned operatively downstream from surface 106 and cooperating with second frustoconical ledge 116 to define an annular orifice 118. Steam may thus flow from a cylindrical plenum chamber 114 machined in projection 102 via orifice 118 into bore 42 of inlet 40 to draw in yarn 12 and hurl it against screen 44. Orifice means 104 is held rigidly in place by threaded backing plug 102 and may easily be changed when a different yarn is to be crimped. Steam enters inner plenum chamber 114 via apertures 150, Fig. 4 in cylindrical wall 102 from an outer plenum chamber 135 formed by the outer surface of wall 102 and the inner surface of annular housing 132, the outer chamber being sealed by O rings 142, 144. The foraminous surface is provided by a woven screen 154 of square or rectangular shape and having a downward projecting tab 156. The screen overlies a rectangular aperture 162 in platten 158 so that tab 156 contacts rectilinear edge 160 of platten 158. This ensures that the rough direction of the woven screen is parallel with the yarn outlet passage 52. The crimped yarn exits via passage 52 and tube 54 then is deflected by pivoted wire 60 into receiving tube 64. Tube 64 forms part of a J box (24, Fig. 1, not shown) which collects the yarn, heats it in the right hand limb of the box and cools it in the bottom of the J box whilst the yarn is untensioned in order to heat set the crimps. The set yarn is drawn over baffle (82) through eyelet (84) and past tension vanes (86-92) to remove tangles.

Title: Remotely controlled lock assemblies and apparatus incorporating  such assemblies
IPC: E05B47/06
Filed: 1973-12-07
Abstract: 1456547 Lock A A HILLS 7 Dec 1973 56836/73 Heading E2A A key-operated lock is provided with means for remotely preventing withdrawal of the key or operation of the lock. In a first embodiment shown in Fig. 1, a barrel lock 20 employs a key 21 which, in the usual way, may only be inserted and withdrawn in the 'locked' position of the lock. The inner end of the key has a notch 23 provided in its back edge, and a pivoted detent 25, operated by electromagnets 26, 27 may engage the notch to retain the key in the lock when desired. The detent 25 is indexed in the holding and releasing positions by a spring 28 engaging notches in its outer end. The fitted edge of the key engages a notched lever 32 which is displaced by rotation of the key to operate contacts 54, 55, Fig. 10, and a pin 35 on the barrel, Fig. 11, acts on another lever 33 to operate further contacts 67, 68. A shoulder 41 on the detent 25 prevents rotation of the key in the retained condition. Initial insertion of the key tilts lever 32 to close contacts 54, 56, but rotation of the key closes the other contacts 55, 57 and then through lever 33, contacts 67, 69. The lock may be used to prevent unauthorised use of hired equipment e.g. a vehicle, and when this is not hired out, it is plugged in at 98, 99, 100, 101, see Fig. 13, to a lease depot which, when switch 103 is closed, passes current through contacts 54, 56 (closed because the key is inserted) to the key-retaining electromagnet 26 to prevent the key being removed by the client. At the same time, a relay 109 is energised to disable an alarm 111 at the depot by current also through contacts 54, 56 showing that the key is in place. When operation of switch 103 at the station energises releasing electromagnet 27, the key may be turned to close ignition circuit contacts 55, 57, and starting contacts 67, 69. In a modified circuit (Fig. 14, not shown) the station circuit is released by an identity-cord reader instead of by an attendant. In the alternative form of lock shown in Fig. 15, rotation of the lock barrel and, hence, withdrawal of the key is prevented by a plunger 145 entering a hole 143 in the barrel. The plunger is controlled by electromagnets 146, 147 and indexed by a spring-loaded plunger. A rotary switch acts in the same way as the switches described above.

Abstract: 1,199,950. Article dispensing apparatus. SOUND DIFFUSION (SALES) Ltd. 10 Dec., 1968 [21 Dec., 1967], No. 58117/67. Heading A4T. In apparatus dispensing articles from one end of a line, an electrical signal is transmitted to a remote indicator in accord with the length of the line to indicate the number of articles in store. In e.g. a hotel-room cabinet 10, Figs. 2, 3, having push button radio 12 and internal communication speaker 11, two frames 20 support stacks of articles with an insulated slide bar 21 resting on top and a drawer 15, 16 at the bottom, the drawer having a rear ledge 27 connected by springs '29 to upturned flange 28 of a slide 19 normally blocking the fall of articles into the drawer when flange 28 abuts pin 30 released by solenoid 34. On pushing in drawer 15, a micro-switch 32 under ledge 27 is actuated by engaging a downturned flange 33 of slide 19 whereby solenoid 34 is momentarily energised to lift pin 30 allowing springs 29 to pull back slide 19. The drawer with article is withdrawn and pulls the slide 19 into blocking position by allowing the pin to ride over a slide cam 37. The bar 21 descends with the articles and has a contact 22 permanently catching strip 23 leading to a power connection and a strip 25 leading to the micro-switches and solenoid in the return line, contact 22 also connecting with one of contacts 24 corresponding to each article leading via a specific resistance, diode and switching to a meter e.g. at reception, to indicate the number of articles. A bottom contact 26 leads to an 'empty' indicator. The key operated cabinet switch or remote switch can break the micro-switch return and prevent dispensing and remote switches may switch in the indicators at a central desk. The slide 21 may carry a magnet operating reed switches and replacing the specific resistances of contacts 24.

Title: Gas turbine exhaust duct
IPC: F02K1/82
Filed: 1970-12-10
Abstract: 1442740 Jet propulsion nozzles GENERAL MOTORS CORP 10 Dec 1970 58809/70 Heading F1J An exhaust duct structure adapted for cooling to minimize the visible or infrared radiation from the exhaust of a gas turbine engine comprises an annular exhaust passage 21 extending from the turbine 6 to the engine outlet 22 and defined between outer and inner walls 25 and 26, respectively. The outer wall 25 is of a double-walled construction and is fixed to a bolting flange 29 on the engine casing 15. A stiffener ring 30 is bolted to the flange 29 and an outer sheet 31 continues downstream to the engine outlet 22. An inner sheet 33 is made up of a number of overlapping sections 34, 35, 36, 37 and 38 connected to each other by corrugated strips 41 which space the adjacent sections slightly from each other to provide gaps for entrance of film cooling air. An external wall 42 extends from the outer sheet 31 to the stiffener ring 30 and is shaped so as to define between its leading edge and the ring 30 a number of ram air scoop inlets 45 which reeeive air propelled by a ducted fan (not shown) driven by the turbine 6. The air is received in an annular plenum chamber 46 between the external wall 42 and the outer sheet 31. The inner wall or inner body 26 is of bulbous configuration, as a result of which the exhaust passage 21 is blocked from direct sight through it into the turbine 6, and comprises a forward section 49 diverging rearwardly and three converging, overlapping sections 50, 51 and 52 extending to the tip of the inner body. The sections 49, 50, 51 and 52 are connected by corrugated strips 54 in the same manner as the sections of the inner sheet of the outer wall. Sections 49, 50 and 51 include stiffener rings or flanges 55 which prevent direct radiation from the inner surface of the inner body 26 through the film air outlets. The inner body 26 is supported by six radial hollow struts 58 which extend from the external wall 42 through the sheets 31 and 33 of the outer wall 25 to the section 49 of the inner body. The struts open at their inner ends into the body 26 and at their outer ends into the annular plenum chamber 46. Cooling air is thus supplied to the interior of the inner body 26 through the gaps provided by the corrugated strips 54 and also to the space between the sheets 31 and 33 of the outer wall 25 through a number of metering openings 61 in the sheet 31. The size and number of openings 61 is such as to provide the desired division of the air and rate of flow as between the outer and inner walls of the exhaust passage. Each strut 58 comprises a forward U-shaped section 62 and a trailing V-shaped section 63, these being connected by corrugated strips 65 which define outlets 67 for cooling air. The trailing portion 63 which is partially visible from outside the engine is thus bathed in a film of cooling air.
