Title: Water heating apparatus
Inventor: COLLINSON ERIC SAMUEL
IPC: F24H1/28
Filed: 1956-07-11
Abstract: 870,444. Gas-fired combustion apparatus. LUCAS (INDUSTRIES) Ltd., JOSEPH. July 3, 1957 [July 11, 1956], No. 21429/56. Class 51 (1). ). [Also in Group XIII] Air from a chamber a and gas from a pipe e and a chamber d pass through ports controlled by loose disc valves u and v into a mixing chamber w and from there the mixture passes through a flame trap x into a combustion chamber g in a chamber b through which water passes from top to bottom. Ignition is by an electric spark plug y and combustion is pulsatory, the pressure changes causing the disc valves u, v to operate intermittently as referred to in Specification 802,927. Gases from the combustion chamber g pass through flue tubes to an exhaust gas chamber c on which is formed a dome i in the water chamber b. They pass then to a small side compartment m, Fig. 3, and a perforated silencer tube p, to be conducted through a large side compartment ml (which may be packed with loose material for silencing) to an outlet pocket q which may be connected to a flue pipe. The air for the compartment a passes through a similar large side compartment k<SP>1</SP> by way of a similar silencer tube, Fig. 4 (not shown), from a small compartment k into which it is introduced by a side inlet from the atmosphere or a blower. The Provisional Specification describes also the use of liquid fuel and the passing of a mixture of a fuel and air to the combustion chamber through a non-return valve.

Filed: 1960-06-18
Abstract: 938,081. Pitot tubes. WESTLAND AIRCRAFT Ltd. May 9, 1961 [June 18, 1960], No. 21488/60. Class 69 (1). Measurement of airspeed pitch and yaw in a rotary-wing aircraft is effected by a measuring device having in combination means for sensing pitot pressure, ambient static pressure and differential pitch and yaw pressure, respectively, with means for providing static pressure compensation. The device comprises a probe which protrudes three feet ahead of the aircraft fuselage and mounts a carrier 2 with a plug 3 on which is an axial member 4 with a nose-cap 5 which is electrically heated by a de-icing coil 16. In the nose-cap is an axial orifice 6 which senses pitot pressure and two other orifices 7 and 8 which are laterally offset at 40 degrees from the central axis and which sense the differential yaw and pitch pressure. An ellipsoidal fairing 11 between the plug 3 and the cap 5 has holes 12 equally spaced around its maximum diameter. The fairing is specially shaped so that the holes 12 are in a region of super-velocity and are subject to a pressure-ratio which is relatively insensitive both to flow direction and to Reynold's number and the static pressure inside it at 13 is at true ambient value. The orifices 6, 7 and 8 and the space 13 communicate by way of their respective pipes 9, 21, 22, and 14 with an external pressure union 10 from which operates a pitch or yaw meter 27. An altimeter 23 and a rate of climb meter 24 are connected with tube 14 by way of union 10. An air speed indicator 25 and an air mileage indicator 26 also are connected between the tubes 9 and 14 by the union 10.

Title: Compressed air or other gas control valves
Inventor: LAMBERT HAROLD LESLIE
IPC: F16K1/12
Filed: 1957-07-08
Abstract: 844,954. Fluid-pressure servomotor control systems; valves. ROTAX Ltd. Sept. 9, 1958 [July 8, 1957], No. 21505/57. Class 135. A valve for automatically controlling the delivery pressure of air or other gas comprises an inlet body part 11, Fig. 1, connected by radial ribs 14 to a cylinder 10 slidably mounting a spring-loaded piston 17 having a spring- loaded, telescopic connection 19, 22, 25 with a valve closure member 15 slidable on the cylinder 10 to control openings between the ribs 14. A space 16 between the cylinder closure plate 10c and the inner face of the valve member 15 is connected through ports 27 and a restriction 26 to pressure in the valve outlet duct 12 and through a passage 28 in one of the ribs 14 and a relief valve 29 with the atmosphere. Opening and closing of the valve 15 is effected by means of a pair of solenoid-actuated shuttle valves 41, 43, Fig. 12, housed in an inlet body part extention 32 formed with chambers 33, 35 connected to the valve inlet and atmosphere respectively. As shown in Figs. 1 and 2, with the valve 15 closed, a space 10a behind the piston 17 is open to atmosphere through a duct 39 and the chamber 35 and a space 10b in front of the piston to valve inlet pressure through a duct 40, the chamber 33 and a duct 34. On energization of the solenoid 36 the connections to the chambers 10a, 10b are reversed so that the piston moves rightwardly and the valve 15 fully opened. Pressure then builds up in the outlet duct 12 and this pressure passes through the restriction 26 to the space 16 until it equals the outlet pressure. If the outlet pressure exceeds a value determined by the loading of the relief valve 29 this valve will open to vent the space 16 and allow the valve 15 to move towards closure and so maintain the pressure in the valve outlet 12 at a desired value. The restriction 26 communicating with the valve outlet may be replaced by a restriction 31 through the piston 17 which transmits inlet pressure to the space 16 when the valve 15 is open.

Abstract: 1371291 Radio signalling COAL INDUSTRY (PATENTS) Ltd 27 April 1973 [9 May 1972] 21619/72 Heading H4L In a system for communicating in mines, or along roads or railways, a radio transmitter 1 is connected via a radiating transmission line 3 to a receiver 2. A plurality of unidirectional repeaters 8, 9, 10 are connected in the line 3 and the transmitter is controlled from a station 5 which receives demodulated audio signals from the receiver 2. A mobile station 4 includes a receiver for signals on the line 3 and also transmits signals on a different frequency to the line. In operation, signals from station 5 are transmitted from 1 on a frequency f 1  towards the receiver 2 and may be received by any mobile station whose receiver is tuned to f 1 . The operator of a mobile station replies by transmitting on frequency f 2  which can only travel to receiver 2 and thence to station 5. The signals from receiver 2 may also be fed back to the transmitter 1 for via line 7 retransmission on frequency f 1 , thus allowing direct communication between mobile stations. Alternatively if this latter facility is not required, f 1  may equal f 2  and the equipment simplified. In a modification, Fig. 2 (not shown) branches are looped out of the main transmission line each terminating in a receiver and including repeaters as required.
