Title: Internal combustion engine fuel supply apparatus
IPC: F02B71/02
Filed: 1972-11-10
Abstract: 1392976 Regulating fuel gas/air systems; starting free-piston engines A BRAUN 10 Nov 1972 [12 Nov 1971] 52037/72 Headings F1B and F1K A combustible mixture pressurized supply system comprises a first metering orifice 222, Fig. 1 in an air supply line, a second metering orifice 223 in a fuel gas supply line, means for maintaining substantially equal pressures in the respective supply lines immediately downstream of their respective orifices and means for maintaining substantially equal pressures in the supply lines immediately upstream of the respective orifices. In an application to an auxiliary starting fuel supply system for engine 201, a compressed air supply line or receiver 98 supplies air via a temperature regulating device 236, reducing valves 230, 229, check valve 233 to the control pressure take off point 228 via orifice 222 to mixing tube or chamber 213 and starting valve 94. Fuel gas supply e.g. methane or propane, from a fuel gas supply line or tank 104 passes via temperature regulator 236, pressure reducer 232, check valve 234 to pressure regulating valve 226 and thence via orifice 223 to mixing chamber 213 and starting valve 94. Regulator 226 e.g. an air-loaded or dome loaded regulator has a pressure in a control chamber controlled by a line 227 connected to the control pressure at 228 in the air supply line. The merging of lines 216, 217 at 219 provides equal instantaneous pressures immediately downstream of orifices 222, 223. In an application, the air in a reservoir 56, Fig. 2 supplied from a compressor 23 driven by an I.C. free piston engine 22 is used for an auxiliary starting fuel and air mixture system. The arrangement includes a valve 61 which bleeds chamber 34 to atmosphere when the engine is stopped. The valve 61 may be manually operated or operated when a switch 67 in the ignition circuit is opened. A valve 68 is arranged to supply air to both sides of the piston 26 to position the piston assembly for starting. A carburetter or mixer 91 supplies the cylinder 21 with normal running or starting mixture. A switch 112 controlled by movements of the piston rod 24 causes the spark plug 89 to ignite when the piston assembly is in the left hand position. A valve 37 controls the air pressure in borance chamber 42. Chamber 107 supplies scavenge air to cylinder 21. A test exchanger 238 controls the temperature of air from reservoir 56.
Patent GB-522205-A (GB)
Abstract: 522,205. Windows. BRISTOW, C. A. Dec. 2, 1938, No. 35240. [Class 20 (iii)] [Also in Group XXV] A suspended folding window is provided with a vertioally slidable catchbolt combined with each lower carriage, and engageable with a series of holes in the lower track or guide. In the construction. shown comprising t w c sashes hinged together at their meeting edges, each sash has at its outer upper corner, a carriage 1 comprising an L-shaped bracket which is screwed tc the sash frame and carries an upwardly projecting pin 7 The weight of the sash is taken by a square block 8 pivotally mounted on the pin 7 and slidably mounted in the overhead track 9 in the window frame. The block rests upon, and the sash is supported by, the inturned flanges of the track. A similar block 14 is pivotally mounted on a pin 13 carried by a carriage 12 secured to the lower outer corners of each sash, and slides in the lower track 15 of the window frame. The carriage is fitted axially with a bolt 21, Fig. 4, which, by engaging in any one of a series of holes formed in the track 15, is adapted to hold the sashes in any required position. The bolt passes through a spring 25, which is compressed between two fixed abutment on the carriage 12 and by its tendency to buckle exerts a frictional restraint on the bolt. The track 15 is cut away at one or both ends to provide water outlets. Specifications 173,822 and 337,771, [both in Class 20 (iii)], are referred to.

Title: An electrostatic accelerator
IPC: H01J37/18
Filed: 1969-10-29
Abstract: 1,240,399. Discharge apparatus. COMPAGNIE GENERALE DE SYSTEMES ET DE PROJETS AVANCES. 29 Oct., 1969 [30 Oct., 1968], No. 53046/69. Heading H1D. An electrostatic accelerator for charged particles, e.g. for an electron microscope assembly, comprises, within a general enclosure 1 containing a dielectric fluid under pressure, e.g. sulphur hexafluoride at 3 Bar, a charged particle source 3 and an accelerator tube 11 with a slide valve 13 disposed between them which may be closed by a valve control device to isolate them, so that the source may be repaired, for example, without causing air to enter the accelerator tube. The source 3 is located in flange 5 within the general enclosure which together with a movable mating tube 9 forms a separate air lock enclosure isolated from the atmosphere of the general enclosure and which can then be evacuated and brought to the ambient atmosphere. The valve control device comprises a piston 19, coupled via a lever 15 to the valve 13, sliding in a cylinder 21 within which it is constrained to the valve open position by a spring 23. The cylinder 21 is open at one end to the atmosphere of the general enclosure 1 and at its other end normally communicates with the atmosphere of the enclosure formed by tube 9 and flange 5 and when this airlock enclosure is reduced to ambient atmosphere (1 Bar pressure) the resulting unequal pressures on opposite sides of piston 19 cause it to move in the cylinder 21 against spring 23 to close the valve 13. The source 3 can now be repaired or replaced without affecting the remainder of the tube. After evacuation and sealing of source 3, the air lock enclosure is evacuated and refilled with the dielectric fluid under pressure. This will equalize the pressures on either side of piston 19 but the valve 13 will open under the action of spring 23. If access to the accelerator tube 11 is required during repair of the source 3 the valve 13 may be opened by changing the direction of the valve 25 to place the right-hand end of cylinder 21 in communication with the atmosphere of the general enclosure 1 again.
