[Also in Division D1] The invention relates to bis-perfluoroalkanoylphenylenediamine derivatives of the general formula  in which R F  and R<SP>1</SP> F , which may be the same or different, each represent a perfluorinated alkyl radical having from 4 to 12 carbon atoms and R 1  represents the group -NCO Compounds claimed per se 2,4-di-perfluorooctanoyl - amino - phenylisocyanate; 3,4 - diperfluoro - octanoyl - amino - 1 - N,N - ethylene - ureido - benzene. In an example perfluoro-octanoic acid chloride prepared by reacting benzotrichloride and perfluorooctanoic acid is reacted with 3,4-diamino-1-nitrobenzene to obtain 3,4 - diperfluoro - octanoyl - amino- 1-nitrobenzene which is hydrogenated to obtain the corresponding amine compound and then phosgenated to obtain the corresponding isocyanate compound. The latter may be reacted with ethylene-imine to prepare 3,4-di-perfluorooctanoyl - amino - 1 - N, N - ethylene - ureidobenzene. Other examples describe alternative methods of preparation.

Title: Improvements in or relating to thermally-released overload-responsive electrical circuit breakers
IPC: H01H73/30
Filed: 1959-03-16
Abstract: 887,505. Automatic circuit-breakers; switches held set and freed mechanically. TEXAS INSTRUMENTS Inc. March 16, 1959 [May 2, 1958], No. 9086/59. Class 38 (5). [Also in Group XIII] A switch has a bridging member 62 which comprises a bi - metallic element 64 carrying two contacts 84, 86 and two arms 88, 90. The bridging member 62 is biased towards the open position by a spring 94 but may be held in the closed position shown by the ends of the arms 88, 90 engaging an abutment 61 on a member 58. This member is loosely carried on an extension 54 of an actuating member 32 and is biased away from the member 32 by a spring 60. The member 32 is held in the position shown against the bias of a spring 48 by spring latch members 120 engaging an abutment 130 of the member 32. The switch may be opened manually by pulling a knob 38 attached to the member 32, the abutment 130 camming the latch members 120 outwardly so that the member 32 is freed and upward movement of the members 32, 58 and 62 occurs under the action of the springs 48, 94 to open the contacts 84, 106, 86, 108. Under overload conditions, the element 64 warps, moving the ends of the arms 88, 90 away from each other, as indicated in dotted lines, so that the arms disengage from the abutment 61 and the spring 94 forces up the bridging member 62 to open the contacts. As the bridging member moves up, tabs 92 on the arms 88, 90 displace the ends 132 of the latch members 120 so as to release the member 32. The spring 48 then moves the members 32, 58 up into the off position so that when the member 64 cools, the ends of the arms 88, 90 re-engage the abutment 61. Reclosure is effected by depressing knob 38 until the latches 120 re-engage the abutment 130, the contacts being closed by the member 58 acting on the bridging member 62 through the arms 88, 90. These arms may be bi-metallic to compensate for ambient temperature variations. A coloured sleeve 46 indicates the opening of the switch.

IPC: C25B15/00
Filed: 1921-03-24
Abstract: 181,848. Plauson (nÚe Hildenbrandt), G. March 24, 1921. Mineral waxes, extracting.-Substances resembling montan wax are obtained by heating lignite under pressure with caustic alkali solution, mixing the product with sodium perchlorate solution and introducing the mixture into an electrolytic apparatus, which mav be kept hot so that the wax can be run off in liquid form. The arode of the electrolytic apparatus has a very small active area compared with that of the cathode, current being supplied at such a pressure that the anode becomes hot, preferably incandescent. The substances may be fed through a tubular anode, of which only the end is exposed to the electrolyte. As shown, the anode 1 is surrounded, except at the ends, by a porcelain sheath 2. Instead of a single aperture, the anode may be provided with a number of small holes for the passage of the gas &c., or may have a poious surface, for example a coating of silver, platinum, osmium, iridium, carbon, or graphite. Alternatively, the anode may be a solid rod, other means for introducing the reagents being provided. Platinum, graphite, lead, silicon, and silicon alloys are suitable anode materials. The cathode may consist of the cell wall 4, of compressed carbon or other material, and provided with flanges to which are bolted a base 5 and cover-plate 3, which may be of vulcanite, glass, asbestos, &c. A cylindrical diaphragm 7 of earthenware, fire-clay, cement, asbestos, &c. extends from the cover nearly to the base, or in some cases into a groove in the base. An overflow 18 leads to a pump which may return the electrolyte to the anode.

Title: Improvements in control systems for direct current electric motors
IPC: B60L9/04
Filed: 1921-03-31
Abstract: 186,640. Givelet, J. A. M. V. de P. March 31, 1921. Systems for continuous-current motors only.- Direct-current motors are started and accelerated by applying a counter electromotive force furnished by a dynamoelectric machine, the armature of which has a closed magnetic circuit. The dynamo d, driven by a small auxiliary motor m at a speed at which it furnishes a voltage practically equal and opposite to the mains, is connected in series with the working motor M across the mains. The speed of the dynamo is then reduced inserting resistances r, h in a rheostaticbraking-circuit for the motor m. A drum controller C<1>, C<2> effects the necessary circuit changes in order. The speed of the auxiliary motor may be reduced, before being rheostatically braked. The working motor may finally be connacted directly across the line. A seriesparallel group of working motors may be similarly controlled, and the generator may be cut out and reinserted in the transition from series to parallel running. The magnetic circuit of the armature may consist of a rotating or stationary laminated ring. In order to reduce sparking, the arm ature may have several windings in parallel, and subdivided brushes.
