Title: Controlling the operation of a door
IPC: H02H7/085
Filed: 1972-06-05
Abstract: 1395749 Door operating devices WESTINGHOUSE BRAKE & SIGNAL CO Ltd 1 June 1973 [5 June 1972] 26218/72 Heading E2M [Also in Division H2] Apparatus for controlling an electrically actuated door wherein an actuator drives the door between first and second positions comprises means to reverse the motion of the door should the loading on the actuator increase. A D.C. electro motor 1 having a series connected field 2 is controlled by a unit 5 which supplies signals on lines 6, 7 to energise the field winding 2 so as to open or close respectively the door of, e.g. an underground railway train, the position of which door is indicated by an arrow 8. In series with the motor 1 is a threshhold device 9 which detects an increase in motor current should the door meet an obstruction in its travel. The circuitry includes a plurality of logic elements which are arranged such that whilst the arrow 8 is between A and B or C and D the apparatus is insensitive to an output signal from the threshhold device 9 and the motor runs to close the door, the region AB being provided to allow for surges in the motor current on starting and the region CD is provided to accommodate the normal resilience in the rubber edge of the door. Should, however, an obstruction be encountered by the door when the door is closing and the arrow is in the region B to C the output signal from the device 9 causes operation of the logic circuitry such that an enabling input is applied to the OR gate 19 so simulating an OPEN command on line 6 whereupon the motor 1 reverses direction. The motor continues to open the door until a timer 16 times out when the OPEN command on line 6 disappears and the door resumes its closing operation. If desired a counting device may be provided to count the motor reversals when travelling between the region B to C and operative to give an alarm should the count exceed a given number.

Title: Improvements in the application of sheaths to electric cables
Inventor: GRIEVE GEORGE THOMAS WILSON
IPC: H01B13/22
Filed: 1953-09-23
Abstract: 743,819. Cables. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 22, 1954 [Sept. 23, 1953], No. 26251/53. Class 36. [Also in Group XXII] In a method of sheathing a cable body by drawing it by a tow-line into an oversize tube and then reducing the diameter of the tube to elongate it and cause it to fit the cable body, the tow line 9 is threaded through a long, air-tight pipe 3 and is held at one end and connected at the other to a piston 11 which is inserted in the leading end of tube 1 and held stationary by pressure in the pipe 3 while the tube 1 is drawn over the piston into the pipe. The free end of the pipe 3, through which the tube 1 enters, is closed in an airtight manner, the opposite end terminating in an air-tight chamber 4 which is connected to pipe 5 closed by gland 6. After tube 1 has been drawn into pipe 3 the piston is removed from the tow line, which is then used to draw the cable body into the tube 1. The tube 1 and the cable body are then attached together at the free end of pipe 3 and drawn through a reducing die. Compressed air is fed to the pipe 3 from a container sufficiently large to ensure a supply of air at the pressure required to hold the piston 11 stationary and to compensate for any small leakages in the system. A skid wire may be applied to the tube 1 as it is drawn into the pipe 3, a winding head being provided adjacent the free end of the pipe for this purpose, and for unwinding the wire from the tube 1 on to a reel as the tube is withdrawn from the pipe for the drawing down process, the speed of rotation of the winding head being regulated by a device which frictionally engages the tube (see Group XXII).

Title: Improvements in or relating to relief valves
IPC: B64D13/04
Filed: 1949-10-13
Abstract: 694,235. Fluid-pressure servomotor-control systems; valves. GARRETT CORPORATION. Oct. 13, 1949 [Nov. 12, 1948], No. 26311/49. Class 135 A valve adapted to be mounted externally on the wall of an enclosure such as a pressurized aircraft cabin to relieve positive or negative pressure in the enclosure and also adapted to be opened at will to equalize the pressure inside the enclosure with that outside comprises a main valve member 47 controlling a port 14 in the wall 15 of the enclosure, a closed chamber 25 spaced from the valve member 47 and having a movable wall 24 operatively connected to the valve member 47, and a pilot valve 40 operated by the movable wall. The movable wall comprises a diaphragm 24 having inner and outer parts 24b, 24a separated by clamping rings 27, 28 the downward movement of which is limited by stops 21a. The latter are constituted by the upper edges of spaced U-shaped struts 21 connected to a valve seat member 22 and a ring 31 by which the diaphragm 24 is clamped to a head 20 to form the closed chamber 25. The inner portion 24b of the diaphragm is clamped between discs 36, 37 of which the latter supports an annular pilot valve 40 forced by a spring 49 against a spherical seat member 46. The member 46 is carried on an external threaded stem 45 having a restricted passage 44 connecting the interior of the enclosure to the chamber 25. The valve member 47 is adjustable on the stem 45 and its position is maintained by a lock nut 48. The diaphragm is moved in the valve closing direction by a light spring 41. The chamber 25 may be connected to the atmosphere at any time to open the valve 47 by a conduit 52, containing a valve 51 which may be located inside or outside the enclosure. In the case of an aircraft cabin, it would be located inside for operation by the pilot. When the valve 47 operates to relieve positive pressure within the enclosure, the pressure within the chamber 25, being substantially the same as that in the enclosure, rises sufficiently to depress the disc 36, 37 and the diaphragm part 24b so that the pilot valve 40 leaves its seat 46. Thereupon the pressure in the chamber 25 drops, the diaphragm is lifted off the stops 21a and the pilot valve 40 entrains the seat 46, the stem 45 and the main valve 47 which remains open until the pressure in the enclosure is restored to normal. To relieve negative pressure, the diaphragm portion 24a is merely lifted off the stop shoulders 21a by the superior atmospheric pressure acting against the pressure in chamber 25 over the annular area B, the pressures acting on the valve member 47 and the diaphragm being substantially balanced over the central area A. Specification 694,299 is referred to.

Abstract: 362,858. Two-way repeaters. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Crisson, G. ; 29, Colonial Terrace, East Orange, and Wright, S. B. ; 310, Western Drive, South Orange, both in New Jersey, U.S.A.) Sept. 8, 1930, No. 26759. Convention date, Sept. 10, 1929. [Class 40 (iv).] In a system comprising 4-wire sections, e.g. London-Ireland, Newfoundland-New York, and a long intervening two-wire submarine cable section, the transmitting branch of the 4-wire circuits is normally disabled at E1 so that noise from subscribers' lines is unable to operate the anti-singing and echo-suppressing relays E2, H2 at the cable terminal station, which are made very sensitive so that the delay introduced by the network D2 may be very small, or that D2 may even be omitted. Echo-suppressing relays controlled by the receiving branch are provided at A1, A2. The volume in the transmitting branch is kept constant by means of the apparatus VR1, e.g. an amplifier with a potentiometer which is controlled by an operator or automatically. Similar apparatus VR2 which may, however, be a transmission regulator controlled by a pilot current from the exchange in London &c., is provided in the shore station. Automatic gain control may be provided in the receiving branch. Received currents pass via a weak amplifier G2 and attenuation equalizer K2 to the main amplifier G<1>2. A further amplifier M2 is provided not so much as an amplifier as a one-way device to prevent the operation of A2 by unbalance currents when speech is being transmitted. Grounded shields are provided for the hybrid coil at the cable terminal and the first amplifier. Shields between the windings of the hybrid transformer and the transformer N2 are connected to the input side of the first amplifier and to the cable sheath but not to ground. The first stage at least of the amplifier must therefore have a separate battery. To prevent its operation by noise, the amplifier detector B2 controlling A2 should be insensitive to high voice frequencies. The Specification comprises details as to the gains and losses in various parts of the circuit and discusses the effect of the hybrid coil 12 in nullifying the effect of the relaxing current, i.e. a gradually decaying unidirectional current which flows out of the cable when speech ceases to be transmitted.

On each occasion it is desired to "up-date" a data file stored alternately on one of two tracks 3 and 4 of a magnetic tape store 1, the entire file is read from one track, for example from track 3 as shown, passed to a data processor, symbolized by an adder 20, where it is up-dated in accordance with incoming data on a lead 25, the up-dated file is recorded on the other of the two tracks, track 4 as shown, and a switch 15 is changed over. Thus on the next occasion the file has to be up-dated the file is read from track 4 and the up-dated file is recorded on track 3. By virtue of this if an error (for example of parity) is detected in any cycle of up-dating the cycle can be repeated since the original file will not have been erased by having been over-written with the erroneous up-dated file. As described every up-dated file is also recorded on a track 5.
