Title: Improvements in and relating to electric switches
IPC: H01H9/22
Filed: 1922-07-11
Abstract: 204,792. British Thomson - Houston Co., Ltd., (General Electric Co.). July 11, 1922. Switch mechanism interlocking with lids; switches, quick-action.-A casing for enclosed switchgear comprises a detachable pivoted cover 6, a portion 7 of which forms a hinged lid, and interlocking arrangements whereby neither cover nor lid can be opened or closed unless the switch is open. The cover 6 is mounted on a bracket 11 which pivots on one side of the switch casing by means of hooks, one of which is locked by the overlapping edge of the end 2 of the casing. Detachably mounted in the casing is a combined switch and fuze cut-out, the switch portion lying beneath the main portion 6 of the cover, and the fuze portion lying beneath the lid 7. The switch comprises blades 31 pivoted at 29 and adapted to enter contact clips 30. The blades 31 are connected by an insulating bar 32 which carries two spring yokes 34 of which the ends 35, Fig. 4, break the shock of closing the circuit, and the ends 36 have elbows engaged by the switch-actuating rod 37. The rod 37 is engaged with lost motion by a shaft 39, Fig. 7, fixed to a crank 40 and a snap action is given by a dead centre thrust spring 42 arranged between a fixed bracket 25 and a member fixed to the rod 37. The locking arrangements for the lid comprise a member 22 fixed to it and having a tip 53 which rests on the top of a, flange 47 on the crank 40 when the switch is closed. When the switch is opened, the flange 47 moves clear of the tip 53 allowing the lid to be opened. The tip 53 then engages one end of the flange 47 and prevents the switch being closed. The cover is locked by a hasp 14 engaging a lug 18 and being padlocked, and to prevent the hasp being raised when the switch is closed a finger 54 on the crank 40 is adapted to overlie the portion 19. The switch may be locked " off " by inserting a padlock in a slot 55 in the path of a shoulder 56 on the crank 40.

Abstract: 572,716. Systems for indicating liquid level. SIMMONDS DEVELOPMENT CORPORATION, Ltd. Nov. 17, 1943, No. 19187. Convention date, Nov. 17, 1942. [Class 40 (i)] A selsyn system for indicating the level of liquid in a tank of such a shape that two or more floats are necessary to provide for the total range of levels employs a separate transmitter for each float with means by which the control of the indicator is transferred from each transmitter to the next. In Fig. 1, in which two transmitters LT, HT, of the kind described in Specification 483,450, are employed for a tank such as that shown in Fig. 2, the resistances 216 are connected in series to form a closed loop and spaced points are connected over wires 1, 2, 3 to the three coils 232 of an indicator of the kind described in Specification 548,447. At one end of the resistance 216 of the transmitter LT is an adjustably mounted cam contact 20 which is connected to the slider 214 of the transmitter HT so that the latter becomes effective when the slider of LT engages the cam contact. This arrangement may be extended to three transmitters, two of them being provided with cam contacts 20. In a modification, Fig. 3 (not shown), the sliders 214 are connected in parallel, and cams 20 are provided at the adjacent ends of the resistances 216 for disengaging the sliders therefrom. In the arrangement of Fig. 4, which is suitable for a tank of the kind shown in Fig. 5, the transmitters LT, HT are arranged in parallel rather than in series, and the cam contact 220 is chosen as regards its length and position to transfer the control at a convenient level. This arrangement also may be modified by connecting the sliders in parallel and providing cams on both resistances at their adjacent ends. Specifications 471,224 and 561,194 also are referred to.

Title: Processes of making concentrated chlorhydrin solutions
IPC: C07C29/66
Filed: 1924-08-13
Abstract: 235,044. Marks, E. C. R., (Carbide & Carbon Chemicals Corporation). Aug. 13, 1924. Chlorhydrin solutions in a concentrated form are obtained by introducing caustic alkali and chlorine into a weak chlorhydrin solution and then passing a gaseous olefine in to combine with the hypochlorous acid formed. Preferably the chlorhydrin solution is circulated continuously and caustic alkali, chlorine and olefine are successively introduced therein. The gaseous olefines are repeatedly forced through the reaction liquid in a vessel 1 by means of a pump 3 and a valved pipe 2, which is fitted at its lower end with a diffuser 14. The reaction liquid is circulated by the pump 9 through a tube 8 into which chlorine is introduced by the pipe 12 at the same time that the equivalent quantity of caustic alkali is admitted from the tank 10 through the pipe 11. The reaction liquid whose chlorhydrin content is thus built up overflows continuously through the pipe 13 to the tank 14. A cooling coil 15 may be employed to maintain the reaction liquid at a temperature which is preferably below 25‹ C.

Abstract: 498,758. Flow meters. ADAMS, A. H. July 12, 1937, No. 19248. [Class 69 (i)] [Also in Group XIX] In a device for measuring the rate of consumption of liquid fuel by a power unit, for example, a '' miles per gallon " indicator for a motor vehicle, the fuel is supplied to the unit by a pump in excess of the needs of the unit, the balance of the delivery being byepassed at each stroke of the pump into a measuring device. A diaphragm type of petrol pump 1 has its output side connected to (a) a pipe 16 leading to the carburetter and (b) an accumulator chamber 20 containing a rubber bag 22 inflated with air at a pressure much less than that required to overcome the spring of the fuel pump. The intake conduit 28 of the pump is provided with a valve 26 and ports 34 communicating with an expansible chamber comprising a tubular rubber diaphragm 30 stretched over a perforated cylinder 32 within a vessel 38 filled with air. Another vessel 40 is filled with air of the same volume, temperature and pressure as that in the vessel 38, and the two vessels'are connected by conduits 41, 42, to a U-tube 45 containing liquid, the displacement of which affords an indication of the expansion of the tubular diaphragm 30 per stroke of the pump, such expansion corresponding to that portion of the delivered volume not taken by the carburetter. A number of scales may be provided on the U- tube to indicate the fuel consumption when the engine is in high, low or intermediate gear.

Abstract: Leucosulphuric esters of 2-aminoanthraquinone and its nuclear substitution products (e.g. amino, alkyl, alkoxy, or halogen substitution products) are prepared by reacting a metal salt of the corresponding leuco compound, or a complex comprising such metal salt, with a sulphating agent in a neutral organic liquid as reaction medium in presence of an amide derived from a secondary amine. Organic liquids specified are benzene, hexane, cyclohexane, ethylene dichloride, acetone, acetonitrile, benzonitrile.  The metal salts or complexes comprising such may be made by treating the 2-aminoanthraquinone with metal in neutral organic liquid in presence of a quaternary ammonium halide, the sulphating agent being added to the mixture so obtained.  A weakly acidic substance (e.g. a phenol, an amide, an organic acid, or a 1.3 diketone) may be added.  A nitrogenous base such as cyclohexylamine, ammonia, methylamine, isopropylamine or a-picoline may be added.  In examples, 2-aminoanthraquinone or its 3-chlor or 3-brom derivative is reacted with methyltriethylammonium chloride and zinc dust in ethylene dichloride, with and without phenol and cyclohexylamine, followed by sulphation with the compound of dimethylformamide and sulphur trioxide or chlorsulphonic acid.
