Title: Improvements relating to automatic position control hydraulic servo-mechanisms
Inventor: ARROWSMITH JOHN RICHARD
IPC: F15B21/08
Filed: 1959-01-20
Abstract: 947,146. Fluid-pressure servomotor control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 20, 1960 [Jan. 20, 1959; Sept. 16, 1959], Nos. 2017/59 and 31508/59. Heading G3P. In an automatic position control servo mechanism an hydraulically actuated power device for imparting movement to a member is connected to two reservoirs selectively connected to a source of other fluid under pressure. The error signal is derived from a continuous comparison of a signal representing the position of said member with a signal corresponding to the desired position of said member. The invention is applied to a servomotor system for positioning the table of a drilling machine along X and Y co-ordinates. The X-co-ordinate position of said table is continuously measured by a potentiometer device 51, 52 and by a more accurate inductive measuring device 54, 55, 56, 57 and the resulting signals are compared with desired value signals derived from manually operable selector switches or from record tapes. For a large error the coil 64 controlled by the discriminator 63 is energized so that the amplifier 65 receives the error signal and in accordance with its sign actuates the solenoid operated valves 30, 31 to supply air under pressure to one or other of two oil containing cylinders 8 or 9 the other one of which is connected to exhaust. The coil 39 is also energized for large errors so that the valve 37 is open and oil can flow from the selected cylinder 8 or 9 to one end of a double acting jack 16, 21, 22 through either of the stop valves 15, 18, the other end of the jack being connected through the valve 18 or 15 to the cylinder 9 or 8 to provide a rapid coarse positioning of the table. When the error falls below a predetermined value the coil 39 is de-energized to close the valve 37 so that the oil supply to the jack 16, 21, 22 must now all pass through the capillary restrictor 38 in parallel with the valve 37 so that the piston 21 slowly approaches its final position. The stop valves 15, 18, may be manually or automatically closed when the work table is in the desired X-co-ordinate position. The table is now moved in the Y-axis by a jack 42 operated in the same way by the oil from the cylinders 8 and 9, and the coarse and fine error signals being derived in the same way as described. The stop valve 37 and the capilllary tube 39 may be replaced by a throttle valve which is moved to a nearly closed position when the error becomes small. The cylinders 8 and 9 may each be replaced by a pair of separate cylinders for the oil and air respectively the pistons in said cylinder being interconnected.

[Also in Divisions C4 and C5] A method for the internal treatment of gas pipe-lines, e.g. to prevent leakage at socketed joints, comprises mixing a treating agent with a liquefied gas and spraying the mixture through a nozzle into the lines by means of its own vapour pressure. Suitable treating agents are hydrocarbon oils, e.g. lubricating oils boiling above 300‹ C. (naphthenic oils being preferred), mixtures of distillation residues of mineral oils with aromatics, e.g. asphaltic bitumen with benzene, and aromatics alone, e.g. benzene or its homologues. Suitable liquefied gases include propane and butane, and halogenated hydrocarbons, e.g. methyl chloride. The treating agents, which are preferably soluble in the liquefied gas, may incorporate packing activators, revivers and preservers, surface-active agents, anti-corrosion agents, dust-binding or wetting agents, and coating agents, e.g. bitumens, paints and resins. The method is preferably carried out while gas is flowing in the line.

Title: Method and apparatus for coding and decoding digital information
IPC: H03M7/00
Filed: 1973-01-18
Abstract: 1407163 Digital transmission; coding GENERAL MOTORS CORP 18 Jan 1973 [28 Jan 1972] 2581/73 Heading H4P A coding method comprises sensing each bit and generating an output stream which if a pair of like adjacent bits is sensed produces a first transistion at a first time if the sensed pair is 11 or a second time if sensed pair is 00. The state of the next bit is inverted if a next same bit follows a pair of like bits. If an alternate pattern follows of at least 7 bits, a second transition is produced as output at 2 or 2¢ bit periods dependent on the commencing bit and a series of third transitions every 1¢ bit times is produced after the second transition until a minimum of two bit times prior to detecting a further pair of adjacent bits of the same type following the alternate pattern. The arrangement provides not more than one transition each 1¢ bit time and is never at one level for more than f bit times hence stabilizing D.C. level in an output bit stream. The coder has a 9 bit input register 12 receiving NRZL data. A bit in position 8 is compared with position 9 by comparator 14 which triggers an output state controller 16 at the beginning of bit time if 8, 9 are 1's, and middle of bit time if 0's thereby introducing a state change. Comparator 14 also enables seven bit alternate pattern detector 18 and pulse generator 20 which produces 1¢ bit interval pulses. Detector 18 senses level of bits 1-7 in register 12 and produces a START output to pulse generator 20 when 8, 9 are like and 1-7 alternate. If alternate pattern commences 10 (01), pulse generator 20 is enabled ¢ (1) bit thereafter and causes 16 to produce a first state change 2 (2¢) bit times later; means 20 then issues a series of pulses at 1¢ bit times until disabled by 3 bit non-alternate detector 22 responsive to bits 5-7 in register 12. When 5, 6 are at the same level i.e. STOP signal is fed to generator 20. Output of compator 14 is also fed back to register 12 which switches level of bit 8 following detection of a pair of like bits in sections 7, 8 so that only discrete pairs of 0's or 1's are detected and shifting of 000's or 111's through positions 8, 9 is not interpreted as 00's or 11's. Other Figures showing logic diagrams are described in detail, together with a decoder illustrated in block form in Fig. 5 (not shown).
