Title: Improvements in or relating to hydraulic remote control devices
IPC: F15B11/10
Filed: 1955-04-28
Abstract: 778,331. Fluid-pressure servo motor-control systems. CENTRE DE RECHERCHES HYDRAULIQUES ET ELECTRIQUES. April 28, 1955 [May 15, 1954], No. 12285/55. Class 135. An hydraulic servomotor control system for controlling the displacement of an output member in correspondence with the movement of a remote control valve, comprises a motor simultaneously driving three constant output, volumetric pumps, two of which, 4-5, 6-7, supply pressure liquid to opposite ends 17, 18 of a servomotor cylinder 15 having a piston 14 connected to an output member 3 and the third supplying pressure liquid to the chamber 10 of a cylinder 9 slidable on an extension 8 of the motor shaft. The cylinder 9 which is loaded by a spring 11 disposed between the cylinder and a collar on the piston-rod 13 is connected by a line 34 to a remote control leak-off valve 35 and is formed with arms 28, 33 which engage spring-loaded sleeve valves 25, 30 slidable on extensions of the rotary shafts of the pumps 4-5, 6-7. The sleeves 25, 30 are formed with ports 26, 31, respectively, which permit leakoff from one or other side of the piston 14 depending upon the direction of movement of the valve 35. On, for example, movement of the valve 35 to decrease the leak-off therethrough, pressure in the chamber 10 increases to move the cylinder 9 leftwardly against its spring 11 and at the same time allow leftward movement of the sleeve valves 25, 30 to uncover the port 26. Pressure liquid then leaks out of the end 17 of the cylinder 15 to unbalance the pressures acting on the piston 14 so that it moves to the right to displace the output member. At the same time the spring loading is increased which returns the cylinder 9 and the sleeve valves 25, 30 to their initial equilibrium positions. The continuous rotation of the extension 8 and the extensions of the shafts of the pumps 4-5, 6-7 prevents sticking and reduces friction between 'these parts, the cylinder 9 and the sleeve valves 25, 30. The cylinder 9 and sleeve valves 25, 30 may be replaced by plungers slidable in hollow extensions of the motor and pump shafts and the double-acting, servomotor may be replaced by a rotary motor which through a screw mechanism reciprocates the output member. Several output members having the same or different displacements may be controlled simultaneously. Their displacements being dependent upon the areas of their respective pistons.

Title: Insolubilization of water-soluble cellulose ethers
Inventor: ANDERSON ARTHUR WILLIAM
IPC: C08B11/20
Filed: 1963-04-02
Abstract: A composition comprises a water-soluble cellulose ether and a diglycidyl ether of a polyoxyalkylene glycol containing from 2 to 20 oxyalkylene units, each of which units contains 2 to 3 carbon atoms. Preferably, the cellulose ether is methyl cellulose and the polyoxyalkylene glycol is polyoxyethylene glycol.  The diglycidyl ether may be present in an amount of 1-30% by weight of the composition.  Subsequent heating of the composition, suitably at 60-200 DEG  C., and especially at 100-160 DEG  C., renders it insoluble in water.  A catalytic amount of a tertiary amine may also be present, suitably 0.1-1.0% by weight, based on the diglycidyl ether.  Specified water-soluble cellulose ethers include ethyl, carboxymethyl, hydroxyethyl, hydroxypropyl, sulphoethyl and hydroxypropyl methyl celluloses.  Suitable ethers are the water-soluble and self-dispersing polyglycol derivatives corresponding to the formula <FORM:1019228/C3/1> in which O-alkylene represents an oxyalkylene radical in which the alkylene radical is a 1,2-alkylene radical containing 2 to 3 carbon atoms, i.e., ethylene, 1,2-propylene or 1-chloro-2,3-propylene, R is the bivalent residue of a starter compound formed by the removal of two active hydrogen atoms from said compound; and x and y are integers whose sum is 2 to 20. Active hydrogen atoms are defined as those reactive toward alkylene oxides in the presence of the usual catalysts for the condensation of alkylene oxides, and such active hydrogen compounds include water, glycols, primary amines, bis (sec. amines), alkanolamines, diphenols, amides and carboxylic acids. Hence polyoxyalkylene glycols having alkylene radicals containing a halogen, e.g. 1-chloro-2,3-propylene, the radical derived from epichlorhydrin, may be used.  In examples, the diglycidyl ether of polyoxyethylene glycol of average molecular weight 400, of diethylene glycol, of dipropylene glycol, and of polyepichlorhydrin of average molecular weight 450 are used with methyl cellulose and triethylamine as catalyst.  Specified catalysts for the reaction of glycidyl groups with aliphatic hydroxyl groups include trimethylamine, triethylamine, tripropylamines, and water-soluble trialkylamines in general, trialkanolamines e.g. triethanolamine, and heterocyclic bases, e.g. pyridine, N-alkyl piperidine, quinoline, N-alkyl pyrroles and pyrrolidines.  In examples, the cellulose ether and the polyoxyalkylene glycol diglycidyl ether are dissolved in water, catalyst added, films cast from the solution, dried, and then heated to insolubilize the composition.

Title: Ac track circuit apparatus for continuous rail track
IPC: B61L1/18
Filed: 1971-05-04
Abstract: 1341465 AC track circuit GENERAL SIGNAL CORP 4 May 1971 [4 May 1970] 13099/71 Heading B7N In a continuous rail alternating current track circuit with ends defined by track shunts ST, a transmitter and receiver are provided at each end of the circuit for detecting the presence of a vehicle in an end zone of the circuit and at least one other receiver is provided at an end zone responsive to the transmitter in the other end zone for detecting the presence of a vehicle in the mid zone of the circuit. A periodically operating test shunt is provided at each end zone circuit. The shunt 14 is periodically applied by a signal from pulse generator 13 whereby at each application the increase in output current from transmitter T 1  is detected by receiver R 1  which supplies an output to shift the frequency of oscillator 10 supplying the transmitter output. This periodic shift is detected by receiver R 1 <SP>1</SP> at the other end of the circuit and this provides an output to control the application of shunt 20 across the other end of the track circuit. The corresponding increase in output current from transmitter T 2  is detected by receiver R 2  which supplies an output to shift the frequency of oscillator 26 feeding transmitter T 2 . The frequency shifted signals received in receiver R 2 <SP>1</SP> at the first and of the circuit control a flip-flop 30. If the flip-flop output signals correspond with those supplied from the switching pulse generator 13 a gate 50 operating via flip-flop 57 and driver circuit 58 maintains the track circuit relay 41 energized. A train present in either end zone prevents the periodic shift in frequency and a train present in the mid zone prevents transmission of the signals between the circuit ends, either condition leads to release of the track relay. Between the switching pulses the track circuit signal can be coded for cab signalling purposes. A frequency shift repeater station can be provided to extend the length of the circuit.
