[Also in DivisionF2] A valve comprises a tubular member (6), Fig. 1, not shown, having a closure surface (8) at one end which co-operates with a fixed seat (9) to control flow through the member from an inlet (2) to outlets (3). The member (6) has an external piston (7) formed thereon which is moved in a cylinder (4) in response to pneumatic pressure in a chamber (4a) on one side of the piston under the control of a manually actuated valve 19, Fig. 3. A chamber (4b) on the other side of the piston is vented by passages (11) which connect with the passages (3) when the valve is closed, but are closed by the member (6) when the valve is open. The valve is disposed in a pipeline leading from gas storage vessel 17, Fig. 3, to a gas blast circuit-breaker 14. Movement of the valve 19 to exhaust the chamber (4a) allows the member (6) to be moved by the pressure of the gas in vessel (17) acting on the larger diameter portion (12), to the open position. For moving the member (6) to the closed position the valve 19 is actuated to connect the chamber (4a) with the vessel 17 through a non-return valve 22 and auxiliary storage vessel 20. The seat (9) may be disposed in the inlet to the valve. The member (6) may be loaded to the closed position by a spring.

Abstract: 1428294 Bending tubes; shearing WELDUN TOOL & ENG CO 22 March 1974 [29 Nov 1973] 12781/74 Headings B3A B3E and B3W Apparatus for bending a length of tubular material 10 comprises a frame 44, Fig. 1, a table 58, Fig. 4, supported on the frame for lateral movement relative to the frame and to the path of endwise advancement of the material into the apparatus, a bend head 60 carried by the table and being pivotal relative to the table about a pivot axis extending transversely to the path, the bend head including a plurality of parts alignable to the path, and means 94, Fig. 16, for shifting the table relative to the frame wherein a selected part is aligned with the path to accommodate material of a given diameter. The tubular material 10 is supplied from a reel supply section 16 which includes a plurality of stanchions 26 each supporting a reel 12. Each stanchion carries a brake mechanism. A feed section 18 is utilized to pull the material from the reels 12 and feed it through a cutter section 20 and into a bending section 22. The cutter section includes a plurality of belt driven cutter units 48, each comprising a disc-type cutter 49. The bend head 60 includes a plurality of bend stations 62, Fig. 4, each of which comprise a bend block 64, a clamp block 66 and a drag block 68. The blocks have a plurality of parallel grooves 76 parallel to the direction of advancement of the material to form a set of grooves to accommodate material of a particular diametrical size and form material into bends of varying radii. Each clamp block is operatively associated with an hydraulic power cylinder (78), Fig. 17 (not shown), which causes the clamp block to shift toward and away from the bend block 64 between a tube clamp position and a tube release position. Gears 80, 82 are supported on the table and are rotatable by means of a power cylinder 84 to cause pivotal movement of bend head 60. Before the bending operation, guide tubes 88, 86 are aligned with each other and with the longitudinal axis of respective associated cutter units 48. The material 10 is fed over the ends of mandrel rods 118, Fig. 3B, which extends through hollow stripper rods 102 provided at the stripper section 24. After contacting the rods 102 a switch 122 is tripped causing subsequent reduction of speed of the drive of feed section 18 Contact of rod 102 with a switch 124 causes stoppage of the feed section drive. The material is then clamped in position, tensioned, and the  cutters advanced through the material until it fractures under tension. After retraction of the cutting units the bending is performed. Posts 92 projecting upwardly from the table 58 serve as limit stops for the bend head 60 and a lift 94 is provided to vertically and horizontally move the table 58 and bend head relative to bed member 56. The lift is actuable via a handle 96.

The means to move the first and second reticles are servomotors 30, 24, receiving signals from amplifiers 32, 26, which move the tapes 16, 12 on which the reticles are mounted. The first reticle comprises a scale of degrees above or below the horizon and the servomotors maintain the reticle 0 degrees on the horizon. The second reticle indicates the desired flightpath, and the third also includes markers representing the aircraft datum line and stall speed. The reticles are substantially in the focal plane of a lens 18 which together with a lamp 20, a mirror 19 and the glass 10 form a projector. A filter surface only allows passage of light of the most intense wavelength emitted by the lamp 20 to prevent damage to reticles caused by extraneous light entering the projector.

Abstract: 1389166 Flame sensors ELECTRONICS CORP OF AMERICA 19 March 1973 [31 March 1972] 13061/73 Heading F4T [Also in Division G1] A burner flame sensor comprises a tube 26, Fig. 1, having a bracket 22 for fixing it on a fuel nozzle 14, the tube having an outlet port 28 and air inlet 140 whereby air can be passed through the tube to remove ash and debris, a spring 40 centring a cooling jacket 42, Fig. 2, in tube 26, coolant supply and return pipes 50, 52, a pair of photo-electric flame sensors, preferably ultra-violet sensitive avalanchebreakdown types, 60, 62 aligned with respective optical windows 64, 66, and a drive 78 oscillating a shutter 74 back and forth to intermittently block the path from windows 64, 66 to sensors 60, 62 for simulating periods of flame absence. Sensor 60 is connected to fail-safe circuitry 90, Fig. 1, which is synchronized with the cycling frequency of shutter 74 to keep a relay 92, and thus a solenoid oil-fuel valve 20, energized during periods of simulated flame absence. Relay 92 will drop out if the flame goes out, if sensor 60 signals flame presence during simulated absence, and if sensor 60 otherwise fails. Sensor 62 similarly energizes a relay 112 and the valve 20 through circuit 110, whereby valve 20 is only closed if both relays 92, 112 are de-energized. De-energization of only one relay causes an alarm light 100 or 120 to be energized and is indicative of the probable failure of the associated sensor and the probable maintenance of flame. If both relays are simultaneously deenergized an alarm light 136 is energized to indicate probable flame failure. Sensors 60, 62 may be as disclosed in U.S. Specification No. 3,416,041, and circuits 90, 110 may be as disclosed in U.S. Specification No. 3,288,195. Valve 20 may be energized independently of the control circuitry by manually operable contacts 122 or 124.
