Filed: 1957-01-18
Abstract: 811,247. Hydraulic systems. CITROEN S.A., A. Jan. 18, 1957 [Sept. 14, 1956], No. 1894/57. Class 69 (2). [Also in Group XXXII] In an hydraulic system comprising a continuously operated pump P and two opencentre control valves D<SP>1</SP>, D2 each controlling the operation of a motor, a valve S is provided which automatically discontinues the supply of liquid to one control valve when the other valve is actuated to connect its associated motor to the pump, and automatically restores the supply to the one control valve if this valve is subsequently actuated. The control valves D1, D2 and their operation are identical. Considering valve D1, in the central position shown pump P discharges through valve S and a line 4 to this valve and thence through a line 37 to a reservoir R. A line 21 leading to an end chamber of the valve S is also connected to the reservoir through valve D1. Movement of the valve spool 24A to the left blocks the reservoir line 37 and opens a motor line (not shown) to line 21 and to the inlet line 4. The resulting increase in pressure in line 21 moves the valve S to the left, closing the supply line to the control valve D2, so that control valve D1 only is supplied. If the spool of the valve D2 is now moved to the left, so that both valves are actuated, its motor line is opened to a line 20 leading to the other end chamber of valve S, and the pressure in this motor line centralizes the valve S and both control valves are supplied.

Patent GB-1025104-A (GB)
Title: Process for production of hydrogen
IPC: C01B3/50
Filed: 1963-01-18
Abstract: <PICT:1025104/C1/1> In the production of hydrogen from hydrocarbons by the steps of reforming with steam and shift conversion, an improvement is effected by maintaining a steam-to-carbon ratio of 3 to 7 and a pressure of 300 to 700 p.s.i.a. in the reformer, converting 50 to 85% of the hydrocarbons to hydrogen in the reforming step, removing carbon oxides and steam from the process stream and cryogenically separating unconverted hydrocarbons from hydrogen to give 96% to 99.5% pure hydrogen. Contaminated process condensate (principally dissolved CO2, H2 and hydrocarbons), obtained after shift conversion, may be vaporized and recycled to the reformer. Low-purity hydrogen from an extraneous source may be purified by addition to the process stream prior to cryogenic separation.  As shown, hydrocarbon and steam are preheated, e.g. to 750 DEG  F., and fed to reformer R-1, inlet pressure being e.g. 500 p.s.i.g. and outlet temperature being e.g. 1480 DEG  F. R-1 exit gases are cooled to e.g. 700 DEG  F. in B-2 before entry to shift converter C-1. Contaminated process condensate may be evaporated in boilers B-2 and B-3.  Two or more catalysts may be used at different temperatures in the shift conversion stage.  C-1 exit gases pass through boiler B-3, heat exchanger E-1, and boiler B-4, in which spent solutions from the CO2 removal stage are regenerated by heat exchange. Condensate is collected in separator S-1 at e.g. 260 DEG  F. from the process stream, which is further cooled to ambient temperature in heat exchanger E-2, more condensate being removed in separator S-2. Carbon dioxide is removed from the process stream before unconverted hydrocarbons are separated in the cryogenic unit at e.g. -270 DEG  F. to -290 DEG  F. and 250 to 650 p.s.i.a.  If the hydrogen is required for high pressure hydrogenation, compression to e.g. 650 to 1500 p.s.i.a. may be effected prior to the cryogenic step. Carbon monoxide may be separated in the cryogenic unit to give hydrogen containing not more than 100 p.p.m. carbon monoxide. Purge gas or recycle gas from a hydrogenation unit may be added to the process stream either before or after the CO2 removal stage.

Title: Improvements in or relating to power-driven winches
IPC: B66D1/36
Filed: 1960-01-21
Abstract: 874,836. Guiding rope on to winch drums. BOUGHTON, T. T., and BOUGHTON & SONS Ltd., T. T. Jan. 21, 1960 [Jan. 21, 1959], No. 2266/59. Class 78 (5). A fair lead 14 guides rope 13 on to winch drum 1 with the aid of fluid cvlinder 19. Roller 10 is driven from drum 1 via gearing 4, 5, 6, 8 and carries helical groove 11. Groove 11 is operatively connected to the spool of valve 28, via follower 12 and linkage 33, 32, 29, so that axial movement of the follower 12 causes axial movement of the said spool. The cylinder of valve 28 is carried by fluid cylinder 19, the piston rod 24 of which is fixed stationary as at 25. Fluid under the control of the valve 28 enters at 26 and is discharged at 27 on the other side of the piston, the movement of the piston cylinder effecting the movement of the fairlead 14. Operation.-As the winch drum rotates follower 12 is displaced to the right and, in turn, the spool of valve 28 is also displaced to the right relative to the cylinder thereof. Fluid therefore enters at 26 to cause displacement of cylinder 19 to the right but, at the same time, to tend to close valve 28. In consequence, follower 12, the valve spool, cylinder 19 and the fairlead 14 reciprocate backwards and forwards to cause the rope to wind evenly on to the winch drum 1.

Title: Frame Synchronising Circuit for a Time Division Multiplex Communication System.
IPC: H04J3/06
Filed: 1968-01-18
Abstract: 1,156,104. Multiplex pulse code signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 18 Jan., 1968 [23 Jan., 1967], No. 2698/68. Heading H4L. The invention provides a frame synchronizing circuit for a time division multiplex P.C.M. terminal or a central exchange. As described, the system provides 24 channels V1 to V24, of which one (V24) is used to carry a framing code, each channel time slot consists of 8 digit time slots t1 to t8 and each digit time slot is divided into basic time slots a, b, c, d. Incoming signals Sm, whose timing is controlled by the remote station, are supplied to a framing code detector FD which provides a signal if the framing signal is received at the correct time as controlled by the local clock so that the output gate is inhibited and a bi-stable E5 remains in its normal or " 0 " state. However, if synchronism is lost the bi-stable E5 is set to its " 1 " condition at time V24.t8.C. At time V1.t4.a the state of bi-stable E5 is transferred into a shift register SR having four stages and at time V1.t6 the bi-stable E5 is reset to its " 0 " state if not already in that state. This cycle of operation is repeated and the information stored at SR is shifted each time one position towards the right. The arrangement is such that if three errors occur in a search period of four cycles, a decoder DC produces an output signal E<SP>1</SP> which at time V1.t2 sets a bi-stable E to its " 1 " state. This causes a signal M to <SP>"</SP> be generated at time V1.t3.C for the duration of one basic time slot which controls a one bit shift of the relative time position of signals Sm and V24. The bi-stable E is reset during the next cycle if the bi-stable E5 remains in its " O " state. Otherwise hunting continues.
