Title: Improvements in or relating to ganged variable inductance devices
Inventor: RICH CHARLES WILFRED
IPC: H01F21/00
Filed: 1950-09-14
Abstract: 706,479. Adjusting radio apapratus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 8, 1951 [Sept. 14, 1950], No. 22663/50. Class 40 (5). [Also in Group XXXV] A ganged tuning coil assembly comprises a number of inductance coils each having in circuit with it an exposed C, U or similarly shaped conductor, each of which is bridged by a movable short-circuiting brush, and means for mechanically linking the brushes so as to alter their positions simultaneously. The coils C, Figs. 1, 3, are located with their axes parallel, in cut-outs provided in a pair of U-section clamping bars U', U' of insulating material, which are held together by bolts B. On the two end faces of each coil are fixed U-shaped conductors R connected in series with the coil, the limbs R', R' of each conductor being bridged by a shorting brush S. Each brush is supported by a stirrup SR, Fig. 4, attached to an insulating arm M which in turn is attached by means of a spring plate P to a common sliding member ST. If one of the coil units is of larger inductance than the others, correct ganging may be obtained by means of a coupling loop (not shown) connected in parallel with one of the U-shaped conductors and tightly coupled to the winding of the coil unit.

Title: A process for preparing alcohols from unsaturated compounds
Inventor: NIEBLING KARL FRIEDRICH JOHANN
IPC: C07C29/04
Filed: 1953-08-18
Abstract: An alcohol is prepared by treating an olefinically unsaturated aliphatic or cycloaliphatic compound with ozone to form an epoxide and thereafter subjecting the ozonide to hydrogenation at a temperature between 100 DEG  C. and 300 DEG  C. in the presence of a hydrogenation catalyst.  A liquid diluent may be present during the ozonization step and may be suitable as a solvent in the hydrogenation step.  Suitable catalysts for use in the hydrogenation step are, for example, nickel, copper chromite and finely divided platinum and palladium catalysts.  In the examples (a) cetene is ozonized with a mixture of oxygen and ozone and the ozonide so formed is then hydrogenated in the presence of nickel on kieselguhr to give pentadecanol-1 and some methanol; (b) octene-1 is ozonized and the resulting ozonide is hydrogenated using a nickel catalyst to give heptanol-1; and (c) a mixture of C12-16 technical olefines is ozonized and then hydrogenated using a nickel catalyst to give a mixture of higher alcohols.

Title: Process for improving the properties of aqueous dispersions
Inventor: WHITBY FRANCIS JOHN
IPC: C09K23/00
Filed: 1960-06-29
Abstract: The stability of an aqueous dispersion is improved by treating the dispersion at an elevated temperature with a stabilizing agent comprising a water-soluble organic polymeric polyelectrolyte.  The temperature may range from 30 DEG  to 80 DEG C. and the polyelectrolyte may be one that contains anionic groups and is made by the polymerization or copolymerization of an ethylenically unsaturated carboxylic acid, anhydride or a half-ester thereof. In particular the polyelectrolyte may be an alkali metal salt of a copolymer of styrene with a lower alkyl half-ester of maleic acid while the specified comonomers are ethylene, propylene, butylene, vinyl toluene, vinyl acetate, vinyl formate, vinyl methyl ether and vinyl chloride.  The dispersion is preferably of a polymer, e.g. natural rubber, polymers of butadiene, isoprene, isobutylene, styrene or acrylonitrile or of copolymers of two or more such monomers and more preferably those of butadiene (40)-styrene (60). A viscosity depressant, e.g. the dioleate of a polyethylene glycol may also be present.

Abstract: 738,391. Radiators for heating buildings ; hot-water boilers. HARVEY, H. Sept. 14, 1953 [Sept. 12, 1952], No. 22896/52. Classes 64 (1) and 64 (2). In a hot-water radiator in which two sets of radiator sections 10 are arranged on opposite sides of a combustion chamber 15 for a fluidfuel burner 18, one or each set of sections has its upper and lower portions interconnected by pipes 23 extending above the burner flame, each pipe having sinuosities formed in a single plane. The pipes loop around baffles 21 extending from plates 13 closing the inner half-sections of the sets. An asbestos-lined cover 14 of inverted- U shape closes the space 15 between the radiator sets at the back, front and top except for a fume outlet connected to a flanged aperture 28 in a flue box 26 which is supported by the upper of two frames 17 which connect the plates 13. The flue box contains a boiler 29, unconnected with the water of the radiator sections, supported by bearers 30 above the open bottom 31 of the box and above an auxiliary burner 32 for heating the boiler when the radiator is not heated. There are openings 27 in three sides of the box 26. The burner 18 is controlled by a relay valve 19 and governor 20. A short, vertical pipe 25 connected at its ends to one closure plate 13 is for housing a thermostat. A radiator may form a central heating point to which other radiators are connected by pipes. The Provisional Specification describes a radiator in which two large ducts, with horizontal or vertical flues of various cross-sectional shapes through them, interconnect the water spaces of the two sets of radiator sections above a combustion chamber.

A data processing system comprises a CPU connected (e.g. by a ring bus) to a plurality of ancillary units (e.g. I/O control units or other CPU's), each of which includes means to generate a unit selected signal when it correctly or falsely responds to an address signal received from the CPU, there being means to generate a warning signal if two or more of the ancillary units generate unit selected signals in response to the same address signal. A unit selected signal is generated if an address bus portion of the ring bus has the address of the unit on it and at least one bit on a data bus portion of the ring bus is 1. The unit selected signal is ORed on to a line of the ring bus, and if the incoming portion of this line at any unit producing a unit selected signal already has such a signal on it, a warning signal is ORed on to another line of the ring bus. The CPU responds to the warning signal causing each unit producing a unit selected signal to identify itself to the CPU by a signal on a respective line.
