Abstract: 769,790. Anchor-bolts. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES. June 10, 1955 [June 26, 1954], No. 16722/55. Class 89(1). An anchor-bolt, e.g. for mine roofs, comprises a rod 1 with screwed end 10 engaging a nut 4 having an inclined face 4a for engagement with the face 3a of a member 3, free on the rod. During insertion of the bolt in bore 11, member 3 is supported by shoulder 2 on the rod, and the rod is turned to move the nut down against member 3, thereby to wedge the rod in the bore. To remove the bolt, the rod is turned to move the nut up and member 3 is prevented from binding thereagainst, as the rod is pulled out of the bore, by a shoulder 8 abutting a shoulder 9 on the rod.

Abstract: 1508476 Program jumps NIXDORF COMPUTER AG 23 April 1975 [24 April 1974] 16852/75 Heading G4A The addresses for addressing a section 22 of a store 20 containing instructions, each of two words, are generated by an arithmetic unit 27 adding the contents of registers 28, 29 and are passed to an address register 25 via an instruction address register R7 the output of which is also supplied to register 28. During normal operation register 29 receives the constant 2 via gate 31 whereas for a jump instruction a jump address increment is supplied to register 29 from store 20 via gate 32, controlled by a microprogram control unit 34, and added to the contents of R7. As the instructions are stored in store 20 only at even addresses the least significant bit in the address from arithmetic unit 27 is not stored in instruction address register R7 but is used to indicate, when it is 1, that a subprogram jump is to take place, this being detected by an AND gate 33 which supplies a signal to microprogram control unit 34 to cause the address in a stack index register R6 to be incremented by 2 via arithmetic unit 27 and this address is used to address a return address stack 24 in store 20 to store a return address. The subprogram is then carried out by addressing a subprogram in section 23 of store 20. Data addresses are fed to address register 25 via a gate 37, the data being stored in section 21 of store 20.

Abstract: 885,288. Fluid-pressure servomotor control systems. GENERAL PRECISION Inc. May 19, 1959, No. 17015/59. Class 135. An hydraulic servo valve, suitable for aircraft control systems of the kind wherein a small electrical signal controls the valve for the power operation of flight control surfaces or other equipment, comprises a spool valve movable in a housing by fluid pressure applied to its opposite ends through fixed orifices from a source, these ends communicating through longitudinal passages in the spool with respective passages opening at the outer surface of the spool, and means for selectively varying the size of these openings to differentially vary the pressure on opposite ends of the spool and produce movement thereof. Pressure fluid is supplied through a central inlet 12 in the housing 1, past a filter 35, to opposite ends of the spool valve 4 via a pair of fixed orifices 38, passages 45, 51 and 48 at opposite ends of the housing. Longitudinal passages 55 from opposite ends of the spool communicate with corresponding radial passages 7, 8 opening on either side of the centreline at an outer face of the spool over which a control valve member 10 is movable to selectively vary these openings and permit fluid from one or the other end of the spool to escape to a central drain port 25 of the housing. Control valve member 10 is carried on an arm 5 fast with an armature 6 pivoted at 58 between the poles of an electromagnetic torque motor 18 which receives the controlling signal. A bellows device 22 seals this torque motor from the hydraulic side of the valve. Pressure fluid also received through the inlet 12 passes via a pair of internal ports 29 to two annular chambers of the spool. A second pair of internal ports 28 which communicate with respective utilization ports 13, 14 of the housing, can be placed by a pair of lands 27 of the spool in communication through the annular chamber of the spool with the pressure ports 29 or with the drain port 25. As shown in Fig. 15, the utilization ports 13, 14 are connected to opposite ends of a power piston 151 for operating the aircraft control surfaces or other equipment, pressure fluid being supplied and exhausted alternately to and from opposite ends of this piston on movement of the control valve 10 to either side of the transverse centreline. Various modified forms of a control valve carried on a pivoted armature and movable over a longitudinal face of the spool 4 are described.

Title: Improvements in and relating to the electrolysis of alkali metal chloride solutions
Inventor: HEISKELL THEODORE WILLIAMS
IPC: C25B1/46
Filed: 1960-05-14
Abstract: In a method of making chlorine and caustic soda by electrolyzing brine in a cell comprising alternate cathodes and anodes mounted in parallel alignment with intervening partitions of porous asbestos and a normal operating level of brine above the tops of the electrodes, sufficient HCl is added to the brine to maintain 1-15% by weight of acid, while raising and maintaining the level of brine at least 3 inches higher than the normal operating level and preferably 8-12 inches.  The level of the brine anolyte which contains at least 4.3 g. alkali metal per litre, is preferably 11-15 inches above that of the catholyte.  A level indicator is used.  The normal level of overflow in the brine cell is stated in an example to be 6.5 inches and the cell walls are raised to provide for the higher level above the electrodes.  The amount of HCl preferred is 4% by weight of brine, and is added at a rate which takes into account the chlorine produced duing electrolysis. Tables are given showing that less CO2 and chlorates are formed in the catholyte, and electrical efficiency is improved. Graphite anode consumption is also reduced. U.S.A. Specification 1,866,065 is referred to.

[Class 38 (i)] A terminal for resiliently clamping a conductor between a screw and a terminal body, to accommodate differential thermal expansion between the conductor and body and creep of the conductor, comprises a body 1 and a clamping screw 5 supported on a resiliently deformable part 7 of the terminal, with means for locking the clamping screw against rotation after adjustment. As shown, deformable parts 7, 71 of the terminal may be formed by saw cuts 3, 3<1> open to the conductor channel and terminating bluntly or in a transverse hole 4. The locking means may comprise a plate 6 adjustably supported above the body by a locking screw 8 which on being tightened binds the clamping screws 5, 5<1> to tapped holes in the plate. The body may alternatively be formed of a strip metal sleeve with overlapping edges cut to form leaf springs, the locking screw drawing the edges together or apart to bind the screws. The latter may wholly occupy blisters or cavities in the conductor channels when tightened down with the conductors absent. Alternatively, the saw cuts may be spaced from the conductor bore, the clamping screw projecting through an aperture into the bore, supported by a saw cut leaf spring, with the lock plate a similar leaf spring.

Abstract: 780,655. Saw-tooth generating circuits. TELEFUNKEN GES. June 14, 1954 [June 13, 1953], No. 17364/54. Class 40 (6). The invention relates to circuits for generating a saw-tooth current in a coil 1, of the type in which the return stroke is generating by permitting a free half-cycle of oscillation which is terminated by means of a damper tube 3 connected in series with a voltage boost capacitor 2. According to the invention a further capacitor 14 is provided which is connected between the coil and the transformer so that a parabolic voltage for correcting for increasing deflection sensitivity is set up across said condenser and in order to compensate for non- linearity due to the resistive component of the coil and damper tube. In addition, an impedance is connected to the transformer and the coil to appropriately modify the voltage set up across said condenser. As shown, the impedance takes a form described in Specification 742,082, and consists of the series connection of a resistor 12, a capacitor 10 and an inductor 11. In an alternative embodiment (Fig. 4, not shown), the right-hand end of coil 11 is connected directly to the H.T. supply and the left-hand terminal of capacitor 2 is connected to the upper terminal of the transformer. The driver valve 6 is connected to ganged variable inductors 15, 16 to provide a control of the amplitude of the saw-tooth current produced, as described in Specification 748,429.
