Title: Improvements in and relating to the feeding of boilers
IPC: F22D1/42
Filed: 1926-04-21
Abstract: 251,282. Marks, E. C. R., (Soc. d'Exploitation des Procedes Dabeg). April 21, 1926. Feedwater, supplying and controlling.-In a locomotive and other boiler supplied with water by pumps driven from the main engine, the supply is regulated by a member influenced by the variations in steam pressure produced by movement of the steam regulator. Pumps 1, 4 supplying cold water to an exhaust steam heater 3, and withdrawing hot water from the heater and forcing it into the boiler through a pipe 5, are driven from the engine by a rod 6 connected to the valve links. A valve 10 in the suction pipe of the pump 10 carries a piston upon the underside of which the steam pressure in the valve chest acts against spring pressure on the upper side and opens the valve when the regulator is opened. A valve 9 in the delivery pipe of the pump 1 is operated from the reversing shaft 8. When the valve 9 is closed, water is returned past a non-return valve 17 to the suction pipe 2.

Abstract: 715,803. Control of two D.C. motors. SADLER, A. L. (Salem Engineering (Canada), Ltd.). April 21, 1949, No. 10546/49. Class 38(3) [Also in Groups XXXVI and XXXVIII] In a system for controlling the co-ordinate drive motors of a lathe tool from a record (see Group XXXVIII), the carriage feed motor 180 and the cross feed motor 172 are each similarly controlled as to direction and speed by the polarity and magnitude of a control voltage. The carriage feed motor 180 has a separately excited field and its armature is adapted to be energized from A.C. mains 7-8 -in series with one or the other of reversely connected thyratrons 488. 490, under the control of a double triode 454. The grids 452, 456 of the two triodes 454 are fed with quadrature potentials from the mains 7-8 and these triodes are balanced by the potentiometer 478 so as to produce zero output in the absence of a signal input over line 450. According to the magnitude and polarity of this control signal one of the triodes 454 will conduct more than the other, the resultant output altering differentially the grid potentials of the thyratrons, which are A.C. biased from the supply 7-8. so that one of these now fires for a portion of each positive half cycle of its anode potential. The duration of firing during each half cycle and hence the motor speed depends on the magnitude of the control signal. The cross-feed motor 172 is similarly controlled by an independent control signal applied over line 530 to the grid 538 of a triode pair 532 which operates the motor through thyratrons 534, 536.

Abstract: 1379784 Body harness STANLEY AVIATION CORP 7 March 1972 [22 July 1971] 10643/72 Heading A3V [Also in Divisions B7 and F3] Escape apparatus comprises a socket 22 to be carried by an aircraft, and a motion transmitting connection between the rocket and a harness 26 worn by an airman, a part 21 of the connection serving to restrain motion of the airman's head during his removal from the aircraft by the rocket. The head restraining device 21 comprises a strap 64 passing over the top of a helmet 74 and down either side, being secured in the region of the airman's hips by fittings 104, 120, there being a securing ring 68 held by the strap 64 near the centre of the helmet, and a strap 66 having one end secured to the fitting 104 and extending through a tunnel (128), Fig. 7 (not shown) in collar 94 to the ring 68 back through the tunnel to the fitting 120. In operation tow line 58, connected to the rocket, is attached to the ring 68. The rocket is launched from launcher 34 by the ignition of cartridges in tubes 42 which cause push rods 44 to expel the rocket. The tautening of the line 58 causes firing mechanism 62 to be actuated so that the rocket is propelled by means of forwardly mounted nozzle assembly 52, and also causes the straps 64, 66 to tauten, thus restraining the airman's head against sideways or rearward motion. The tautening of the strap 66 also erects the collar 94 around the man's neck, providing additional restraint. The pulling of the ring 68 by the line 58 also releases a latch so that a visor 150 is moved by a spring from a stowed position to a face-shielding position. After a suitable time the line 58 is severed for example by a charge 144 fired by a fuse ignited by the rocket.
