Title: Improvements in or relating to electric remote selective control systems
IPC: G05D3/14
Filed: 1937-03-22
Abstract: 473,242. Electric control systems. OSTER, L. E. W. MONTROSE-, and POLLOPAS PATENTS, Ltd. March 22, 1937, No. 8435. [Class 40 (i)] In a selective control system of the type employing a transmitter resistance 1 and a motor controlled receiver resistance 1<1> connected in an automatically balanced bridge circuit, the motor 7 is controlled by differently timed relays 10 .. 15 which function to bring the motor to rest instantaneously in a selected position. Normally, when the bridge is balanced, the relays 13, 14 ; 12, 15 and resistances 25, 22 are connected in parallel and in series with relays 10, 11 and the normal current flow is such that relay 11 only is operated to shortcircuit the motor armature. When the bridge is unbalanced, polarized relay 17 in the bridge wire short-circuits relay 11 and relays 10 and 12, 15 or 13, 14 are operated to close the motor circuit and thereby effect rebalancing of the bridge. When relay 17 restores, relay 11 again pulls up to short-circuit the armature, but relays 12, 15 or 13, 14 remain operated for a predetermined time and cause over-excitation of the field due to the reduction of resistance in the motor circuit and a consequent strong braking effect on the armature.

Title: Improvements in or relating to Processes for the Separation of Thorium Compounds from Material Containing the same.
IPC: C22B60/02
Filed: 1919-04-04
Abstract: 129,624. Lindsay Light Co., (Assignees of Ryan, L. W.). July 8, 1918, [Convention date]. Thorium oxide, fluoride, and double carbonates. -A process for the separation of thorium compounds from material containing the same depends upon the solubility of thorium fluoride in a hot or cold solution of an alkali carbonate, ammonium carbonate, or a mixture of sodium carbonate and sodium bicarbonate, a soluble double carbonate being apparently produced. Starting with an acid or neutral solution of thorium, rareearth metals, iron, zirconium, and titanium-as obtained for instance from monazite sandhydrofluoric acid or a soluble fluoride is added to precipitate the thorium and rare-earth metals and to dissolve the precipitated zirconium, leaving the titanium and iron in solution. The filtercake is now heated with the carbonate solution, when the thorium dissolves, leaving the bulk of the rare-earth metals and any phosphates present unattacked. The thorium is precipitated from the filtrate as the hydroxide and the product purified in any known way.

Title: Improvements in Gas Meters.
Inventor: THOMPSON WILLIAM EDWARD
IPC: G01F3/30
Filed: 1918-05-25
Abstract: 121,252. Thompson, W. E. May 25, 1918. Gas meters.-In a wet gas meter, the inlet valve B and its float A are arranged in a chamber E separate from the drum chamber and the valve is arranged to close quickly when the water reaches its low level. The float chamber E communicates with the drum chamber by an adjustable vent-pipe F and an orifice K. When water is poured into the pipe J, it rises in the chamber E, and the air or gas therein passes by the pipe F into the front box; water also passes through the orifice K until it reaches the high lever L and seals the lower end G of the pipe F. As the water in the meter evaporates, the pipe F remains sealed and holds up the water in the chamber E until the low level M is reached, whereupon the pipe F is unsealed and the water in the chamber E descends and causes the inlet valve B to close. The valve is adjusted to close before the water in the chamber E reaches its low level, so that the float is left suspended from the valve. Specification 201.89/12 is referred to.

Title: Improvements in or relating to hair treating preparations
Inventor: DEADMAN LIONEL LESLIE FREDERIC
IPC: A61K8/46
Filed: 1952-04-04
Abstract: A mercapto-carboxylic acid is neutralized with solid ammonium carbonate or bicarbonate or a solid mixture of these salts, and into the mixture there is incorporated either simultaneously or subsequently a solid alkali which is substantially more basic than the ammonium salts and which, when dissolved in water at 20 DEG C. to form a 1 per cent by weight solution, gives a pH greater than 8 but less than 13, the final product being a solid composition soluble in water to form a hair-relaxing solution.  The preferred mercapto-carboxylic acid is thioglycollic acid.  Suitable alkaline compounds more basic than the ammonium salts are sodium and potassium carbonates and the tri-alkali metal phosphates. Commercial ammonium carbonate may be used to neutralize the mercapto carboxylic acid.  In an example 20 g. of 95 per cent thioglycollic acid is neutralized with 20 g. of powdered commercial ammonium carbonate and stirred until evolution of carbon dioxide ceases, whereafter 24 g. of sodium carbonate is added and the whole is mixed to form a dry-free-flowing powder. Specifications 589,956, 721,831 and 748,858 [Group IV(b)] are referred to.
