Title: Improvements in ball cock valves for cisterns
IPC: F16K31/24
Filed: 1920-10-27
Abstract: 172,834. M'Callum, D. Oct. 27, 1920. Ball and float valves; outlets.-A ball-valve is provided with a valve member in the form of a diaphragm which deflects the water through 180‹ through one or more outlet passages. The casing members 1, 2 are separated by the diaphragm 8 and connected by a union 3. Water passes upwards through the passage 5 and is deflected downwards into the annular channel 11 and through the passage 12 to the outlet. The passage 12 may be of semicylindrical form or may consist of a number of small passages, as shown in Fig. 3. A pipe 15 may project downwards into the cistern or may be omitted. The ball float arm is pivoted at 20 and provided with a cam 17 which operates the diaphragm through a plug 16.

Title: Improvements in or relating to television receivers
IPC: H04N5/10
Filed: 1948-11-24
Abstract: 650,522. Television. MULLARD RADIO VALVE CO., Ltd., BRAYBROOK, C. H., and OVERTON, B. R. Nov. 24, 1948, No. 30518. [Class 40 (iii)] One section of a double thermionic valve is employed for the blocking oscillator of the line time-base of a television receiver, the other section in the same envelope being employed as the frame time-base output valve. In the arrangement shown in the drawing a doubletriode valve 8 has one section 10 connected as a blocking oscillator synchronized to operate at line frequency by means of line synchronizing signals applied over conductor 11 and a second section 7 which operates as the frame output valve and which feeds the frame deflector coils via transformer 9, the input to the latter section being provided by the frame blocking oscillator which is constituted by one section 3 of a further double-triode valve 1, the other section 2 of which acts as the frame synchronizing signal separator and to which frame synchronizing signals are applied over conductor 5. The output of the line blocking oscillator is supplied to a line output valve 13 which feeds the line deflector coils 14. The arrangement described is stated to result in an economy of valves and to permit a more compact layout whilst minimizing interaction between the frame and line circuits. Specification 650,521 is referred to.

Abstract: 966,902. Valves. F. H. WATTS. Dec. 5, 1960 [Sept. 9, 1959], No. 30732/59. Heading F2V. An instantaneous gas-fired water heater incorporating a thermostatic control, comprises a fluid-filled thermostatic sensing element 16 in communication with a thermostat bellows 21 and inserted in the heated water flow, e.g. at the outlet 4 of the heat exchange element 15, and a flow control valve 18 operated by the bellows and connected in the water circuit to control the water flow in dependence on the heated water temperature, the bellows 21 being isolated from the pressure in the water circuit, as by a valve stem gland 24. With the object of controlling the outlet temperature under adverse conditions such as abnormally low gas pressure and exceptionally cold weather, the heater is supplied with water through a Venturi 1 which may be made sensitive by restricting the throat with a fitted rod or the like (not shown), and the water flow control valve, as shown, forms a by-pass across this Venturi. The pressure difference set up by the Venturi operates a diaphragm 7 controlling a gas valve 9.

Title: Air intake for an aircraft turbojet engine
Inventor: STAKE NILS KARL-ERIK
IPC: F02C7/04
Filed: 1969-06-23
Abstract: 1,212,489. Gas turbine engines - air intakes. SAAB A. B, June 23, 1969 [June 24, 1968], No. 31500/69. Heading F1G. The invention relates to an air intake structure for an aircraft gas turbine jet engine in which an elongated slot extending longitudinally of the intake duct is provided in a forward portion of the intake wall to allow inflow of ambient air into the intake duct. The object of the invention is to counteract the occurrence of flow of air transverse to the intake duct which would otherwise occur when the longitudinal axis of the air intake is inclined at an angle to the direction of air flow entering the air intake. The invention is described with reference to an aircraft having a pair of air intake ducts 7 disposed laterally of the fuselage 4 each intake comprising an inner wall portion 9, an outer wall portion 10 and a lower wall portion 11. An elongated slot 12 is formed in the lower wall portion 11 adjacent the inner wall portion 9. The wall 9 is extended at 13 and the wall 11 is curved at 14 so that the slot 12 is of nozzle shaped section. In a second embodiment the slot 12a Fig.5 does not extend up to the leading edge of the intake duct. In Fig. 7 a known type of air intake duct is shown inclined to the direction of air flow as indicated by angle α. Such inclination produces a region of lower pressure 27 adjacent the lower wall 20 of the air intake and a region of increased pressure adjacent the upper wall 21, thus resulting in transverse flows 22, 23 in the boundary layer regions adjacent the side walls 9, 10 as shown in Fig. 8. This in turn results in regions of varying pressure and velocity at the compressor face with liability to compressor surge. As shown in Figs. 10, 11 provision of the elongated slot 12 with inflow of ambient air as indicated by arrow 32 inhibits the formation of regions of lower and increased pressure and ensures annular zones of uniform pressure at the compressor face.

Title: Means for transporting a person or other load up and down a staircase
IPC: B66B9/08
Filed: 1952-12-12
Abstract: 740,554. Staircase lifts. PAINE, R. G. March 10, 1954 [Dec. 12, 1952; June 24, 1953], Nos. 31552/52 and 17504/53. Class 78 (3). A device for transporting a person up and down a staircase consists of a travelling platform normally forming a level-surface extension of the bottom stair and provided with runners engaging runways at opposite sides of the stairway so as not to obstruct the stairs for normal use. In one form, Fig. 1, the platform consists of a floor 2 and riser 3 secured between sideplates 4 provided with rollers 5 engaging the runways 6. Sockets 26 on the platform receive hand rail posts 27. Movement of the platform is effected by 'a pair of cables 19 each passed around an anchor pulley 22 and secured to a pivoted cam 23 normally held in frictional engagement with the respective rail 6 by a spring 24 to act as a brake but released when the cable is in tension to raise or lower the platform. Cam 23 is shaped to increase its grip if the platform tends to move back under a heavy load. Cables 19 are passed over pulleys at the top of the staircase and pass to a reversibly driven electric winch (Fig. 3, not shown), controlled by switches at top and bottom of the staircase and, pass to a reversibly driven electric winch (Fig. 3, not shown), controlled by switches at top and bottom of the staircase and, if desired, on the platform. The platform is stopped at the top and bottom of the stairs automatically by limit switches such as 31 engaged by a lug 32 on the platform. The electric winch includes an electromagnetic brake operated whenever the former is switched off. A tension-sensitive switch is included in each cable run to switch off the winch if the tension falls unduly. Preferably the floor 2 is depressible against spring action to actuate a switch arranged by means of a plug on the platform entering a socket at the top of the stairs to connect with the control circuit in this position so that if the platform is left unoccupied for more than a short period it automatically returns to the foot of the stairs. A floor operated switch may be permanently arranged in the control circuit sensitive only to more than a certain weight to prevent a child from operating it. In the Fig. 5 form, an extension 33 for carrying goods is hinged to the platform at 34 so it can be folded on top of the platform when out of use. A guard 36 is projected by cam action when the extension is unfolded and is automatically retracted by a further cam at the top of the stairs for unloading. In either form pivoted guards may be included on the platform to respond to obstructions to stop the winch. The platform width may be made adjustable to suit different staircases by mounting side plates 4 on the ends of telescopic tubular members having locking means, or alternatively plates 4 may have sockets to fit over the ends of tubes sawn to desired length. Also, the shafts of rollers 5 may be adjustable in slots in plates 4 to adjust the platform to be level on different stairways.

According to the present invention a heat-exchanger 60 or 601 is inserted in the feed line 12 or delivery line 15. Engine lubricating oil or other fluid is circulated through the conduit 61. In a further modification, the valve 22 is controlled by means responsive to barometric pressure. Specification 694,318 is referred to.
