Abstract: 1, 121, 086. Hydraulic motors. ELECTROHYDRAULICS Ltd. Jan. 10, 1966, No. 1063/66. Heading F1P. [Also in Division B8] Hydraulic positioning apparatus comprises a differentially extending jack 16 with a cylinder 17, piston 18 and piston rod 18a. The annular area side is connected to a fluid pressure supply (not shown) via a port 19. The full area side is connected by a conduit 20 to control valves 26, 27, 28 respectively connected to ports 29a, 30a, 31a of a valve means 32 with a body 33 in which slides a member 36 biased by a spring 33b to maintain a cam follower 24 in contact with a cam 23 connected to the piston rod 18a. From the fullyextended position shown (which is achieved when valve 26 is open and valves 27, 28 closed) if valves 26, 28 are closed and valve 27 opened an intermediate position is obtained since fluid on the full face side of the jack 16 is connected to exhaust via ports 30a, 35. The supply of fluid under pressure to port 19 thus retracts the jack 16 until the port 30a is covered by land 36b being permitted to move downwards as the cam follower 24 moves down sloping portion 23b of the cam 23. The piston 18 may be further retracted to a third predetermined position by closing valves 26, 27 and opening valve 28. The jack 16 may move directly to a selected position by closing two of the three valves 26, 27, 28 and opening the other. Figs. 2 to 7 (not shown) illustrate various modifications of the embodiment described above.

Patent GB-432028-A (GB)
Title: Improvements in the saponification of cellulose esters
IPC: C08B3/24
Filed: 1934-01-13
Abstract: The acidyl content of organic esters of cellulose is reduced by saponifying the ester with an organic base in the presence of an alkali metal salt which is itself capable of saponifying the ester. Examples of such salts are the alkali metal salts of carbonic acid, hydrosulphurous acid, boric acid, hydrogen sulphide, and phenol. Filaments, threads, and the like to be treated in accordance with the invention may be made by dry or wet spinning processes, with or without stretching, for example, to 200 per cent or more of their original length.  Saponification is preferably effected in an aqueous bath containing methylamine or like acting base and the alkaline salt in solution.  The time of treatment may vary from less than one minute up to three minutes or more depending on the nature of the bath and the temperature employed.  Other substances capable of accelerating the reaction may be present in the saponifying bath, for example, metals such as copper in suitable form may be present as described in Specifications 430,349 and 430,351.  Swelling agents also may be present in the saponifying bath.  The extent of saponification may vary from 8 per cent or less up to substantially complete removal of the ester group.  In an example, cellulose acetate yarn is led in warp formation through a bath containing aqueous monomethylamine and sodium carbonate, washed, and dried.  In another example, sodium sulphide is the alkaline salt used, and the yarn is collected wet in a spinning box.  The Provisional Specification refers to the use of tripotassium phosphate as a suitable alkaline salt for use in the saponifying bath. Specifications 207,562, 323,790, [both in Class 2 (ii)], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, 371,461, 378,858, 389,823, 402,105, 411,094, 417,220, 429,103, 429,447, and 430,350 also are referred to.

Title: Improvements in or relating to electronic counting arrangements
IPC: H03K29/00
Filed: 1949-01-18
Abstract: 712,171. Electronic counting-apparatus. ERICSSON TELEPHONES, Ltd., and ACTON, J. R. Jan. 13, 1950 [Jan. 18, 1949], No. 1324/49. Class 106 (1) [Also in Group XL(a)] A counting arrangement comprises two cold cathode gas-filled discharge tubes CT1 and CT2 (see Group XL(a)), each comprising an anode A, one transit cathode having nine sections (Y1 to Y9), one signal cathode (Z). and first and second guide electrodes (W1 to W10 and X1 to X10 respectively). With a 350v. supply connected across leads HA+ and H-, a glow invests each signal cathode Z and remains thereon until the start key is operated and contacts KS1, KS2 and KS3 complete the circuits of the transit and guide electrodes. The incoming lines L1 and L2 are connected to a 250v. 50 cycle supply and the induced alternating current in the secondary winding of transformer TRA develops a sinusoidal voltage at the point A1 in the network of resistors R1, R2 and R4, which is applied by way of resistor R5 to the first guide sections W1 to W10. The voltage at the point B1, which is similar to that at Al but is retarded in phase in consequence of capacitor Cl arranged in series with resistor R3, is applied by way of resistor R6 to the second guide sections X1 to X10. When the potential on any cathode is some ten volts negative with respect to an adjacent cathode on which the glow is resting, a tangential field is set up, under the action of which the glow transfers to the said cathode. Thus, under the influence of the pulses applied to the guide electrodes, the glow steps along the cathodes until it again reaches the signal cathode Z whereupon a pulse is developed across resistor R8 and is applied through capacitor C2 to the trigger electrode of a conventional gas-filled trigger valve TV, the anode of which is connected to a 200v. supply HB+. The adjustment of the potential divider VR1 is such that the pulse fires the valve TV, whereupon a long negative-going pulse is developed at the anode of the valve and is applied through capacitor C4 to a network, consisting of resistors R12, R13 and R14 and capacitor C5, which is also connected at B+ to a 24v. supply. The network modifies each incoming pulse so that the wave shape of the pulse at the point A2 which is connected to the first guide sections W1 to W10 is different from that at the point B2, which is connected to the second guide sections X1 to X10. The glow in the valve CT2 steps along the cathodes under the action of the pulses until it again reaches the signal cathode Z, whereupon an output pulse is received at OP. The output pulses may be connected to one or more further counting stages and thence to suitable counting or registering means, or by way of amplifying arrangements of known type, or directly, to suitable counting or registering means. Tubes capable of counting in other scales than ten may be substituted for the tubes CT1 or CT2 and the arrangement can be employed to count pulses of different wave shape and duration at inconstant speeds.

Abstract: 1,211,255. Controlling reactors. SIEMENS A.G. 10 Jan., 1968 [11 Jan., 1967], No. 1525/68. Heading G6C. In a steam or liquid metal cooled fast breeder reactor the core is shaped to reduce the probability of a reactivity increase caused by coolant loss, i.e. the coolant void effect. The core shape induces an increase in the neutron leakage at the core centre, where the maximum void effect occurs. The height of the fissile core 1 increases with radial distance from the axis of symmetry. Breeder blankets 3, 4 surround the core 1. The prompt critical value of reactivity is less than the maximum void effect. In an alternative form, the fissile zone may be stepped to provide the reduced central fuel mass.
