Title: Hydraulic remote steering system
IPC: B63H25/28
Filed: 1956-04-26
Abstract: 800,391. Steering ships. MERCIER, J., and MERCIER, B. April 26, 1956 [June 30, 1955 ; Sept. 29, 1955], No. 12873/56. Class 114. [Also in Group XXIX] Hydraulic remote steering mechanism for ships comprises a transmitter which may be rotated in either direction, a pump rotationally connected to the transmitter, liquid under pressure from the pump being directed by one or more control valves so as to operate a receiver directly or through servo-mechanism, and each control valve being responsive to the reactive forces produced by the resistance to rotation of the pump by the transmitter. In one embodiment the transmitter, consisting of a steering wheel 10, is connected by an endless chain 11 to a pump 13 which is provided with valves whereby it supplies liquid under pressure in the same direction irrespective of the direction of rotation. The chain is engaged by a pair of rollers 21, 23 carried by a rod 20 which is centralized by springs 22, 25 and connected at its extremities to the movable elements of valves 14, 24. The valve 14 is connected by conduits 15, 16 to cylinders 17, 18 respectively having pistons which are connected to a receiver 19 in the form of a lever by which the rudder is adjusted for steering. Conduits 30, 31 connect the valve 24 with a cylinder 29 having a piston also connected to the lever 19, the valve 24 being supplied with pressure liquid by a pump 27 driven by an electric motor 26 and connected to an accumulator 28. When the wheel 10 is turned the resistance of the pump to turning causes slackness in the chain 11 to cause a deflection of the rod 20 to operate the valve 14 whereby liquid delivered by the pump is transmitted to one of the cylinders 17, 18 to operate the lever 19, the other of the cylinders 17, 18 being connected to drain. Deflection of the rod 20 also operates the valve 24 to cause actuation of the piston in the cylinder 29 to rotate the lever 19 in the same direction, but the valve 24 may be arranged to open later than the valve 14. In a modification, a single spring- loaded piston in a cylinder is controlled by a valve which is actuated by movement of the casing of the pump which is pivotally mounted and centralized by springs. Further modifications involve the employment of fluid-pressure servomotors (see Group XXIX).

Title: Improvements in or relating to valves
Inventor: JUKES PETER STUART
IPC: B64D37/00
Filed: 1957-04-23
Abstract: 870,882. Valves. GLOSTER AIRCRAFT CO. Ltd. April 23, 1958 [April 23, 1957], No. 12898/57. Class 135. In a vent valve for an aircraft fuel system a first chamber 5a is defined by the top plate 2 and a combined diaphragm and disc valve unit 3, 12 pressed against a seating by a loading spring 16, the diaphragm 3 also forming the upper wall of an annular vent chamber 5b surrounding the seating and communicating with a vent outlet 6, the disc valve 12 having a central aperture through which passes a needle valve 10 attached to a float 4 and controlling the opening 13 of a vent passage 14 communicating through a non-return valve 15 with the vent outlet 6. The disc valve unit consists of an upper perforated plate 12 against which an unapertured disc 17 is pressed by a spring 18. If float 4 falls valve 10 opens passage 13, 14 allowing the pressure above the diaphragm to fall to atmospheric or other design pressure, under which conditions a predetermined force applied to valve 12 against spring 16 enables the diaphragm to lift for outward venting. When the float rises and valve 10 closes inlet 13 pressure is equalized above and below the diaphragm and the latter is reseated. The effective area of the upper diaphragm surface being greater than the lower increase of pressure increases the sealing force. Inward venting can occur whether or not opening 13 is closed by valve 10, if the pressure in outlet 6 reaches a predetermined value greater than that on the lower surface of the diaphragm, non-return valve 15 preventing inward flow through passage 14. Float 4 is weighted so that valve 10 closes opening 13 during inverted flight.

A frequency-modulated signal is recorded redundantly in a plurality of oblique tracks on a magnetic tape and read out in phase and demodulated to reconstitute the original information free from dropouts. Record (Fig. 1).-The signal 12 modulates a carrier and is combined 13 with a pilot signal from a frequency standard 14. The combined signal is divided into two channels coupled respectively to alternate ones A-D, E-H of eight recording heads on a drum. The signal 12 is thus recorded as two sets of interleaved oblique tracks on the tape (Fig. 3, not shown). Play-back (Fig. 2).-The same or different play-back heads A-H are coupled in the same two channels to preamplifiers and combiners 27, 28 which connect diametrically opposed heads AC, BD, &c. in pairs 29, 31, &c. to circuits 24, 36 which synchronize the information signals by filtering the pilot signal, comparing with the frequency standard 14 and controlling delay lines (Fig. 6, not shown). The synchronized signals 37, 38, &c. are combined in slow switchers 42, 43 to eliminate transients and the two channels combined 44, limited 46 and demodulated 47. Where the information is analogue it is converted (56, Fig. 5, not shown) to NRZ in sync. with the frequency standard and recorded as above, the demodulated read-out signal also being reconstituted in sync. with the frequency standard (Fig. 6, not shown).

Respiratory apparatus for aircraft comprises a liquid oxygen supply connected by separate supply lines 17, 16 to crew and passenger breathing equipment 18, 19 respectively, and a valve 20 for cutting off the supply to the passenger breathing equipment without cutting off the supply to the crew breathing equipment. The top and bottom of a liquid oxygen converter 10 are interconnected by a pressure build-up vaporizing coil 13 in series with a relief valve 12 and a filler valve 11. The cut-off valve 20 may be closed manually when a visual means e.g. dial gauge indicator 22 which is connected with an electrical condenser probe 21 in the converter, or audible means indicates that the liquid oxygen in the converter has reached a predetermined level. Alternatively, the valve 20 may be closed automatically. A condenser probe 21<SP>1</SP> which extends into the converter forms part of a bridge circuit 24 which is in balance when the converter is empty but otherwise gives a signal proportional to the contents of the converter. The signal is fed to a relay 26 which, when the signal strength falls to a valve corresponding to the predetermined low level of oxygen in the converter, operates to close a circuit 27 including a solenoid 28 for closing the valve 20. Application 12954/59 is referred to.

Abstract: 1,119,424. I.C. engine charge forming devices. ATOX TRUST REG. March 21, 1967 [Nov. 5, 1966; Feb. 14, 1967], No. 13181/67. Heading F1B. Mixture is fed to an I. C. engine by a driven worm scroll 26, Fig. 5 of progressively decreasing diameter which compresses the mixture or condensate during its passage through the scroll. The apparatus casing is located beneath the carburetter (20), Fig. 4 (not shown) so that when the throttle valve (not shown) is almost closed the condensate flowing along the walls of bore 30 is collected in recess 23 and together with most of the mixture passes in the direction of the arrows through the scrolls 26 until it is thrown by the pressure plates 27 on to baffle plate 28. The latter projects into and is heated by an exhaustheated chamber 29 and also projects into a lower part of the bore 30. In normal engine operation with the throttle open only the condensate passes through the scrolls. The scroll may be driven by an electric motor or driven from the engine by a speed-controlled infinitely variable vee-belt drive. In another embodiment the mixture from the scroll device is led by a separate inlet pipe (34), Fig. 6 (not shown) to a separate inlet valve (39) in a combustion chamber having normal inlet and exhaust valves. A lean mixture is drawn through the normal inlet valve and a rich mixture is drawn through the separate inlet pipe (39), the two mixtures uniting when the piston is near t.d.c. To prevent premature mixing and to assist stratification the separate inlet valve is opened and closed later than the normal inlet valve. In another embodiment a valve is linked to the carburetter throttle valve so that at lower speeds the mixture is directed through the scroll device and at a certain speed the mixture flows directly into the induction pipe. A measured quantity of the exhaust gas may be fed to the suction opening of the scrolls. The pressure disc and/or baffle plates may be vibrated electromagnetically and the vibration frequency may be adjustable. The scroll device and the baffle plates may be of a material which contributes catalytically to the octane improvement of the fuel.
