Title: Production of hydrogen peroxide by anthraquinone process
IPC: C01B15/023
Filed: 1959-05-20
Abstract: In a cyclic process for producing H2O2 involving successive reduction and oxidation of a solution of alkylated anthraquinone and separation of H2O2, the reduction is effected by contacting the solution with H2 in a fixed bed of hydrogenation catalyst, which is 4-100 mesh, and by passing the solution through the bed at a rate between 20 and 200 litres/min./sq. ft. of catalyst bed cross-section.  This high throughput is obtained by passing only part of the solution from the hydrogenator to the oxidiser, the remainder being recycled to the hydrogenator, say through a cooler.  The catalyst is Raney nickel, or Pd, Ru, Au, Ag, Ir, Os, Pt, or Rh on a carrier, e.g. carbon, carbides, alkaline earth metal or magnesium carbonates, or oxides of Si, Al, Ti, or Zr and the hydrogenation is effected at up to 100 DEG C. and 1/4 to 25 atms. absolute pressure.  A number of suitable alkylated anthraquinones and tetrahydro derivatives are specified. Specifications 669,274, 671,524 and 719,523 are referred to.

Impulses representing the displacement of, for example, a machine tool are applied to two input trigger circuits which deliver two sequences of pulses and their complementary pulses to two identical logic circuits, one of which is shown in Fig. 2, which emit series of pulses on lines V1, V1<SP>1</SP> and zero on the lines V2, V2<SP>1</SP> when the tool is moving in one direction and vice versa when the direction of the tool is reversed. These pulses are then applied to trigger circuits and further logic means to give a sequence of pulses which are sent to a counter and they are also applied direct to further logic means to indicate the direction of count. The initial input pulses in the embodiment described are delivered by two photo diodes receiving light from a disc having two rows of windows radially arranged and displaced with respect to each other rotating in front of a fixed disc having windows of the same width as the rotating disc.

Title: Improvements in or relating to train control systems
IPC: B61L3/12
Filed: 1947-06-30
Abstract: 631,278. Train control apparatus. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and MOTT, J. E. June 30, 1947, No. 17186. [Class 105] Train control and cab signalling apparatus employing permanent and electro magnets on the track is provided with at least two magnetic receivers so spaced along the length of the locomotive that not more than one receiver is ever within the range of influence of any track magnet at one time. As shown the two magnetic receivers 5, 6 normally have their permanent magnet armatures 7, 8 disposed to bear on their contacts 13, 14 so making two parallel connections to a brake magnet 15. The travel is in the direction of arrow 3 and the track magnets are arranged as shown with the track permanent magnet 1 presenting first its South pole. The receiver is not affected till it leaves the other end whereupon the track permanent magnet by the action of its North pole reverses the receiver. The track electro magnet 2 in a similar way when left causes by its South pole the magnetic receiver to return to normal. At a clear signal (track electro magnet 2 energized) the brake magnet will not be even temporarily de-energized since there will always be one receiver magnet normal. Thus no braking arises even at very slow speeds. A short bell signal is given under the control of two slow relays A, B ; relay A is briefly energized by the brief reversal of magnetic receiver 5 and this at its contact A<SP>1</SP> allows relay B to be picked up (stuck up over its own contact B<SP>1</SP>) while magnetic receiver 6 is briefly reversed. If the track electro magnet 2 is not energized then both receivers remain reversed so that the brake magnet is de-energized and a partial braking ensues.
