Title: Valve device for pressure fluid pipes or containers particularly for fire extinguishers
IPC: A62C13/00
Filed: 1937-09-17
Abstract: 499,519. Manually - operated valves. REMUS, V. Sept. 17, 1937, No. 25334. Convention date, March 12. [Class 135] A valve device for obturating pressure fluid pipes or containers particularly fire - extinguishers comprises a valve body 4 containing two coaxially arranged spring-closed lift valves 5, 12 opened simultaneously against the direction of fluid flow by a separate pusher 22, the outer valve 12 and its seat 17 being completely removable from the valve casing without interfering with the inner valve 5. Fig. 1 shows a valve device integral with a fluid pressure pipe 1. The valve body 4 has an apertured partition 8 against which a valve disc 5 with a non-circular stem 10 is pressed by a spring 7 abutting the partition and a collar 9 on the valve stem. A similar valve 12 seats on an annular member 17 which is screwed into the valve casing and have a lateral port 20 opposite the outlet 11. The valves are opened by a lever 2 or the like acting on a push rod 22 having a loose or sliding fit in a closure plug 23. The push rod 22 carries a disc 24 with a packing 25 which co-operates with the member 17 or a packing 26 thereon to prevent the escape of fluid past the push rod when the valves are open. Another form is shown applied to a gas bottle. In this case, the valve 12 is of materially larger diameter than the valve 5, and a packing is arranged between the plug 23 and the disc 24, against which the latter is pressed when the bottle is being filled by fluid entering the outlet 11. Fig. 4 shows a form in which the operating lever 2 may be locked in the open and closed positions by a bell-crank 46 pivoted on the handle 43 of the fire-extinguisher, the forked end 44 of the bell-crank engaging the lever at both sides in the closed position and the hook end 47 engaging the end of the lever in the open position. The forked end 44 may be released through notches 45. In this form the packing 26 is carried by an adjustable stop member 41. In Fig. 6, the valve 12 is carried by a piston 18 with a flanged packing 25. The piston 18 is non-rotatably connected to a disc-like pusher 49 carrying a roller or ball 53 engaged by a cam 48 on the operating lever. The piston 18 and the pusher 49 are adjustably spaced by a threaded ring 50. The piston 18 may alternatively carry a push rod for engaging the valve 12 and may have the member 49 screwed into it.

IPC: H01P1/04
Filed: 1960-07-21
Abstract: 931,325. Sealing waveguides. POSTMASTER GENERAL. June 26, 1961 [July 21, 1960], No. 25526/60. Class 40 (8). A closure member is automatically inserted into a gap between pressurized waveguide sections when the pressure in the system drops below a predetermined value e.g. as a result of fracture. A circumferential gap 3 in a circular waveguide 1 (for e.g. H 01  circular-mode propagation) is shown surrounded by a housing H containing a bellows 9 and a closure member 4 pivoted about a spindle 5. The pressure in the waveguide, the housing and the bellows is normally the same, the bellows being inflated via a tube 10 and a valve 11 which opens when the pressure in the guide exceeds that in the bellows. When the waveguide pressure falls, the bellows expands and a stub 28 rocks a pawl 8 out of engagement with a stop 7 on the closure member 4. This allows a spring 6 to rotate the closure member to the operative position within the gap. At the same time a pressure block 12, attached to the closure member, contacts and opens the valve 11 whereby gas flows under pressure from the bellows into an annular inflatable member 16 on the closure member. This contacts and seals the end of one of the waveguide sections. The opposite face of the closure member may be covered with resilient material to seal the other section. Any water leaking into the system collects in the housing H.

Title: Radio navigation systems
Inventor: PALMER WINSLOW
IPC: G01S1/30
Filed: 1960-07-22
Abstract: 958,579. Radio navigation; telegraphy. SPERRY RAND CORPORATION. July 22, 1960, No. 25597/60. Headings H4D and H4P. In a radio navigation system in which the phases of radio signals received from at least two fixed transmitters are compared for position finding, the signals used are telegraph signals. The start bit of each character is delayed so that a certain harmonic of the bit frequency component is in phase with the same component frequency of the preceding character. At the (or each) slave station, Fig. 3, signals from the master station are compared in phase at 25 with the output of a stable oscillator 27, a phase shifter 30 being provided, together with a servo arrangement, so that the output of phase shifter 30 is in phase with the received master signals. The resultant stabilized output of the phase shifter is used to control the slave transmitter, the transmitted signals being telegraph signals. In the normal way, the slave station monitors its own transmission, the received signals being phase compared at 37 with the output of phase shifter 30 after this output has been phase shifted at 80 by a preset amount which corresponds to the master-slave phase difference required in the loran-type system. A servo system adjusts phase shifter 35 until the output of shifter 37 is zero. At the receiver, which is to determine its position, the master and slave signals are demodulated at 45, 46, the outputs of these units being telegraph signals which are passed to utilization arrangements and also to phase comparators 48, 50. A reference oscillation from unit 47 is phase compared alternately with the master and slave signals in comparators 48, 50, the oscillation passed to unit 50 passing through shifter 49. The output of unit 50 is reduced to zero by a servo loop which acts on the shifter 49. This shows the phase shift between the master and slave signals. The output of unit 48 controls the phase of the reference oscillator 47 relative to the master signals. To ensure correct phasing of the chosen harmonic in each character with the previous character each character passes to a computer device which delays the start bit by the requisite amount. This amount is pre-set and determined by an arrangement, Fig. 6 (not shown), in which all the possible characters are compared with a reference oscillation to discover the character with the most lagging phase angle. All the remaining characters are then allotted a delay which will bring their phase to that of that character. The voltage analogue of these delays are wired in to the computer device so that the appropriate delay is selected when a particular character is to be transmitted.
