Filed: 1944-03-20
Abstract: 577,645. Valves. BRITISH OXYGEN CO., Ltd., and JONES, W. March 20, 1944, No. 5133. [Class 135] [Also in Group VI] In apparatus for the administration of inhalant gases, exhaled gas passes from the mask through the apparatus through valves EV, IV, similar in construction to those shown in Specification 577,644. A similar inlet 56 for fresh gas is also provided. A valve drum 25 mounted within casing 10 is formed with a transverse partition 37, and a port 31 isolated from the other ports in the circumference of the drum by a channel 38, but communicating with an end port 39 which constitutes the gas vent, the gas 'escaping via passage 40 and orifice 41. To prevent air being drawn in through this passage when the apparatus is used to impart forced breathing, a flap valve 42, mounted on hinge pin 45 is provided to close the outer end of passage 40. In the position shown in Fig. 7, all of the expired gas escapes through port 39; as the drum is rotated clockwise, a progressively increasing proportion is returned through opening 33 and port 22 to reservoir R. Further rotation closes the passage 40 and thereafter brings openings 32 (Fig. 7), and 34 (Fig. 6), into register with ports 23, 24 leading to and from the absorber so that progressively more gas passes therethrough, and thence to the reservoir through aperture 35 via a channel defined by partition 37, curved partition 58 and an end wall. The casing 10 houses a second ported drum 53 similar in construction to that disclosed in Specification 550,296, whereby any proportion of the gas may be passed via port 51 through the vaporizer V.

Title: Improvements in or relating to electric protective systems
IPC: H02H3/30
Filed: 1923-02-23
Abstract: 204,647. Electrical Improvements, Ltd., and Beard, J. R. Feb. 23,1923. Cut-out arrangements of the Merz-Price type for conductors and apparatus are rendered insensitive to heavy straight-through currents in a sound feeder due to capacity or other effects by providing two relays at each end, one being highly sensitive but adapted to operate only after a predetermined time while the other is relatively insensitive and quick-acting. In the arrangement shown for a single conductor, a pair of relays C, D in series with one another is provided in the pilot wire connection at each end of the conductor. Each relay C is highly sensitive and slow acting while each relay D is relatively insensitive and rapid acting. The closure of either of the relays C, D at each end completes the trip for the corresponding circulitbreaker. Heavy straight-through currents which give rise to capacity currents may effect the balance while the conductor remains sound, but such disturbances are only temporary and do not last long enough to effect the relays C: on the other hand they are not powerful enough to operate the insensitive relays D. A serious fault on the conductor itself will cause the immediate operation of relays D. The arrangement is applicable to other balanced systems, for example earth leakage protective systems.

Abstract: 849,673. Starter turbines. BORG-WARNER CORPORATION. Feb. 22, 1957 [March 1, 1956], No. 6112/57. Class 110 (3). Fuel is supplied to the burner of a turbine starter through an electrically operated solenoid valve which is opened when the solenoid is energised and a valve in a by-pass around the fuel pump is so arranged that when the solenoid operated valve is opened the by-pass valve prevents the flow of fuel from the outlet to the inlet of the pump. Fuel and air are supplied to the burner of a starter turbine by pumps 13, 12 respectively driven by an electric motor 11  energised by push button controlled by the pilot. During the initial few seconds, the blower 12 purges the combustion chamber of gas, and the pump 13 discharges through the by-pass 16 to its inlet. After this period, the solenoid 37 is energised and the valve member 38 is unseated. This allows fuel to pass to the burners and at the same time to pass through the conduits 48, 62 to act on the piston 50 of the by-pass valve '49 which then closes. This causes the pressure in the discharge duct 22 to rise and the valve 14 to be opened by the pressure on the piston 24. A simple ball check valve in the conduit 35 is closed by the gas pressure in the combustion chamber to prevent further supply of air. A pressure operated starter switch 18 is provided to control the unit.
