Filed: 1968-05-20
Abstract: 1,222,703. Carbamic acid derivatives. HOWARDS OF ILFORD Ltd. 21 July, 1969 [20 May, 1968], No. 23984/68. Heading C2C. The invention relates to a method of making carbamic acid derivatives of either of the formulµ RNHCOONH 3 R or R(R 1 )NCOONH 2 - (R 1 )R, in which R and R 1  denote the same or different organic radicals which do not react with carbon dioxide. According to the invention, the compounds are made by atomizing a liquid primary or secondary amine to form liquid particles of diameter between 5 and 500 microns, and treating the atomized amine with gaseous carbon dioxide at a temperature below the boiling point of the amine under the prevailing pressure and sufficiently low to ensure the production of the carbamic acid derivative in the solid state. The examples describe the production of a compound of the formula from cyclohexylamine and carbon dioxide at 55-75‹ C. Specified other amines to which the process may be applied are ethylamine, dimethylamine, dibutylamine, benzylamine and α- or #-phenylethylamine. Apparatus is described. The products are useful as corrosionpreventing agents for ferrous metals.

Title: Improvements in or relating to electric motor controllers
IPC: H02P7/06
Filed: 1938-08-15
Abstract: 519,114. Control of D.C. motors. WEST & CO., Ltd., A., and DAVID, O. T. Aug. 15, 1938, No. 24013. [Class 38 (iii)] The shunt field 3 of a motor 1 is not strengthened to its full value during return of the controller to the "off" position and thereby regenerative action is prevented, although the field 3 is so strong as to overpower the series field 2 during rheostatic braking During forward movement of the controller, resistances R1, R2, R3, R4 are successively shorted there being an intermediate stage when R1, R2, R3 are all in parallel and in series with R4, thereafter R6, R7, R8 are successively inserted and finally contactor C8 opened. During return movement, normally closed contactors C5, C6 are maintained energized by holding contacts thereon until the "off" position is reached, and thus resistances R6, R7 are kept in circuit with the field 3. During rheostatic braking, resistances R2, R3, R4 are in circuit with the armature and series field 2, and the field 3 is excited strongly with contactor C6 closed or fully with contactor C5 closed. The opposition between the fields gives a braking effort/speed characteristic with a maximum at a predetermined speed.

Patent GB-242333-A (GB)
Abstract: 242,333. Wasley, T. J. J., and Sibilla, F. G. July 31, 1924. Liquid-fuel furnaces; steam, supplying.-Water is used as a fuel in furnaces of all kinds by converting it into steam and projecting it on to highly heated surfaces of refractory material, or metal which is not easily fusible, arranged within the combustion chamber of the furnace. The steam is dissociated and allowed to recombine immediately. The steam may be allowed to impinge upon other fuel under combustion in the furnace such as coal, coke, or petroleum. The Figure shows a boiler furnace for carrying out the invention. The combustion chamber a is lined with refractory material or metal such as tungsten, and is divided into two parts c, d by a bridge b. The furnace is first heated to incandescence by injecting steam and oil through the nozzle q, or by other suitable fuel, or by electricity. When the required temperature has been reached, the fuel is shut off and the steam dissociates in the part c of the combustion chamber and the hydrogen and oxygen recombine in the part d. The combustion products pass through the boiler and over a steam superheater h. Air in regulated quantities may be admitted to the combustion chamber by a damper x. Reference has been directed by the Comptroller to Specification 186,350.

Title: Improved method of introducing highly active metals into sealed containers
IPC: H01J9/395
Filed: 1928-08-24
Abstract: 296,781. Westinghouse Lamp Co., (Assignees of Marden, J. TV., and Lederer, E. A.). Sept. 9, 1927, [Convention date]. Low-pressure metallic-vapour apparatus. - Highly chemically active metals, such as the alkali metals, are introduced into evacuated or gas filled containers, such as electron discharge devices, by mixing a compound thereof, e.g. caesium dichromate or permanganate, with a finely divided metalloid, e.g. silicon or boron, and effecting the reduction inside, the container. The mixture may be pressed into pill form and conveniently supported in the container, or be enclosed in a capsule which is welded or otherwise secured to a metal part of the container and heated by high frequency, induced currents. The dichromate and permanganate can be completely freed from moisture and the metalloids may be rendered gas free by boiling the finely powdered material in dilate hydrochloric acid until evolution of gas ceases, three parts of dried silicon so prepared being mixed with one of caesium dichromate or permanganate. The permanganate is preferred because oxygen is evolved before the alkali metal is liberated, such oxygen being utilised in place of that ordinarily introduced to oxidize the filament. The temperature at which the caesium salt is decomposed is stated to be 900‹ C. but this may be reduced to 700‹ C. by the addition of about one per cent of pure, greasefree, finely powdered aluminium preferably in the form of filings. The invention may be employed for cleaning up residual gases in evacuated containers, purifying gases in gas-filled containers, activating cathode filaments. lowering the starting and operating potential of discharge lamps and rectifiers &c.

Abstract: 879,606. Inductive signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 5, 1960 [July 17, 1959], No. 24651/59. Class 40(5) In an inductive signalling system, e.g. for use with travelling cranes, relatively movable stations A, B are coupled via pick-up coils 12, 13, to an inductive loop 1 for communication with each other or with a fixed station comprising an amplifier 7, microphone 8 and reproducer 9. Normally the stations are switched to the receiving position, a station A or B desiring to transmit being switched accordingly to provide an output via a local amplifier to the associated pick-up coil. The signal currents 14 thereby induced in the loop 1 are supplied via a transformer 4 to the amplifier 7, the amplified signals being coupled via a transformer 5 to a second inductive loop 3 which includes the loop 1 and an earth connection. Thus amplified signals will be received by the station A or B not transmitting and will also be reproduced at the fixed station. Unwanted feedback is avoided since the signals 11 are in opposition in the primary winding of transformer 4. Similarly, signals from the microphone 8 of the fixed station are amplified at 7 before transmission to the stations A, B.
