Title: Improvements in or relating to fluid power-operated control systems
Inventor: ELMER ARTHUR ERNEST HENRY
IPC: B64C13/24
Filed: 1956-04-24
Abstract: 864,047. Fluid-pressure servomotor control systems. BRITISH MESSIER Ltd. April 18, 1957 [April 24, 1956], No. 12518/56. Class 135. A fluid-pressure control system, e.g. for aircraft flying controls, comprises a main piston-and-cylinder unit or jack to provide a power output, a valve controlling the admission and exhaust of pressure fluid to and from the jack, an operator's control for actuating this valve, alternative power-operated means for actuating the valve, and a load-senser responsive to the pressure difference across the jack and arranged to bring the power-operated valve-actuating means into operation to reduce the jack movement when the said pressure difference reaches a predetermined maximum value. Jack 1 of an aircraft flying control system has two pistons 1b, 1c in tandem, admission and exhaust of pressure fluid to and from their respective cylinders being controlled by respective piston valves 2 which are coupled together to a floating operating lever 11. A pilot's control lever 6, pivoted on the end of the jack piston rod, is linked to one end of lever 11 and the other end of this lever is linked to a spring centralized power control piston 3b controlled by a piston valve 4 which is connected, through a floating lever 23 and a long lever 27 on a fixed pivot 29, with a load senser 5 comprising aspring-centralized piston whose opposite ends are connected with oppo-  site ends of jack piston 1c. A torque motor 17 of an automatic pilot acts on one end of the  floating lever 23. Pressure fluid entering the system in duplicate through conduits 34, 35 traverses opposite pressure sides of a pressuresensitive valve 36 and non-return valve 37, 38, to be united at a central pressure connection on the control valve 4. Supply pressure through branches 39, 40 goes to central pressure connections of the respective piston valves 2 and also loads a pair of by-pass valves 41, 42 across the jack pistons to normally closed positions. The ends of valves 2 are permanently open to respective exhaust lines T1, T2. Exhaust fluid from opposite ends of the control valve 4 can pass either to line T1 or line T2 through obturated ends of pressure-sensitive valve 36. This valve normally closes exhaust line T2, and on failure of supply pressure in line 35 it remains in this position, the system then operating only on jack piston 1c. If pressure in conduit 45 fails, the pressure-sensitive valve 36 moves to close line T1 and open line T2, whereupon the system operates only on jack piston 1b. On failure of either supply, fluid is by-passed from one side to the other of the inoperative jack piston through a now open one of the non- return valves 41, 42.

Title: An appliance for use in concrete road construction
IPC: E01C19/50
Filed: 1928-04-30
Abstract: 311,542. Norman, J. W. E. April 30, 1928. Moulding roads in situ.-Roads are cast in situ between boundary moulds formed of channel-section bars which act as depth gauges and allow the reinforcement to protrude through so that the cast sections are bonded together. The moulds are formed of upper and lower channel sections 1, 2 joined by end and intermediate brackets 17 so that the flanges 3, 4 present a working face, the intermediate space being partially or wholly filled by strips 5. When used to allow reinforcement to protrude through, a single strip 5 is used adjustable by slots and bolts on the brackets, and to allow of better bonding of the road sections a core-bar 13 is used to form a recess in one section of the cast material. The mould sections may be joined end to end to form a continuous run. The other flat surfaces of the moulds may be used as gauges for different depths, and are shown at the top of Fig. 1 as used for moulding kerbs, a removable core 15 being used to form the rounded edge to the kerb.

Abstract: 1428474 Automatic position control PADANA A G 16 March 1973 [20 March 1972] 12772/73 Heading G3R [Also in Division F2] In a magnetic bearing system, a sensor produces a signal in response to displacement of a body from a desired position. The signal passes to a regulating device which is connected to an electromagnet through two parallel circuit branches including a capacitor and a resistor and/or an inductor respectively. As shown in Fig. 1, a body 1 is retained in a desired position by a coil 2. The position of the body is sensed by a device 3 which supplies a signal to a regulator 4 to energize the coil 2 as required. A complex impedance 5 is connected between the regulator 4 and coil 2 and comprises a capacitor in parallel with a resistor, an inductor, or a parallel combination of a resistor and inductor, so that voltage control independent of frequency is possible. The regulator 4 may be constructed as described in Specification 1257423 [see Division F2]. A number of embodiments using a plurality of coils are described.

Filed: 1943-08-12
Abstract: Cyanostyrenes are copolymerized in aqueous emulsion with conjugated diene hydrocarbons such as butadiene 1.3, isoprene, and 2, 3 dimethyl butadiene 1.3.  Three component systems containing cyanostyrene, styrene and a conjugated diene hydrocarbon may also be so treated. Preferably, the cyanostyrene constitutes from 20 to 80 per cent of the total monomers.  Temperatures of 38 DEG  to 50 DEG  C. are preferred.  In examples, butadiene and orthocyanostyrene are emulsified in aqueous solution, using a pH buffer and then polymerized; paracyanostyrene is similarly treated.  The cyanostyrene are prepared by halogenating ethylbenzonitrile and pyrolysing the resulting chlorethyl-benzonitrile.  Less than one equivalent of halogen is used and the temperature is preferably 70 DEG  to 120 DEG C., U-V light being present.  Pyrolysis is carried out in the presence of a polymerization inhibitor such as hydroquinone and diphenyl p-phenylene diamine.  In examples: (1) chlorine bubbles through o-ethyl benzonitrile at 100 DEG  to 115 DEG  C. under U-V light to give o-chlorethyl benzonitrile which is (3) pyrolysed.  (2) Chlorine bubbles through p-ethylbenzonitrile at 90 DEG  to 110 DEG C. under U-V light to give p-chlorethylbenzonitrile which is (4) pyrolysed.
