Abstract: 690,514. Supply systems for series-connected space discharge apparatus. GENERAL ELECTRIC CO., Ltd., BOWTELL, J. N., and PEACH, D. C. Oct. 19, 1951 [Dec. 21, 1950], No. 31191/50. Class 38 (iv). A sequential starting arrangement for a plurality of (N) of series-connected discharge lamps 5 ... 8 producing, on closure of a switch 9, light flashes from the discharge of a storage condenser 3 connected across D.C. supply terminals 1,2, comprises (N - 1) starting condensers C3 ... C1 connected, one, C1, across the first lamp 8, the second, C2, across the first two lamps 8, 7 and so on to the (N - 1)th condenser connected across (N - ) lamps, counting from one end of the series, each starting condenser C1 ... C3 being shunted by a leakage resistor R1 ... R3 and having small capacity in relation to that of the storage condenser 3. On closing switch 9 the voltage of condenser 3 is applied through resistor R3 to lamp 5 which strikes, its impedance falls, and the condenser C3 is charged to a large fraction of the said voltage; this is applied via resistor R2 across lamp 6 which also strikes, and so on. A dropping resistor 4 prevents the lamps from operating continuously from the D.C. supply. In a practical embodiment, Fig. 2, not shown, the switch 9 is a gas-filled triode valve and the lamps are U-shaped.

Title: Method and apparatus for the lateral alignment of a railway track
IPC: E01B35/00
Filed: 1964-08-04
Abstract: 1,019,330. Aligning railway tracks. F. PLASSER [trading as FRANZ PLASSER BAHNBAUMASCHINEN]. Aug. 4, 1964 [Aug. 2, 1963], No. 31721/64. Heading G1F. In a method for the alignment of a track 1 at a curve therein, with reference to surveyed fixed points F 1 , F 2 , etc. a chord 2 of specific length, having a device 6 in the middle of the chord for measuring the are height corresponding to the chord length, is moved stepwise into the as yet uncorrected track region, the track at the leading end of the chord being displaced until the actual arc height in the middle of the chord coincides with the desired arc height which is determined from those at the neighbouring fixed points. The fixed points F 1 , F 2  are located at known distances from the desired position of the track and the chord 2 is carried by three trucks, the forward truck M having means for lateral displacement of the track, a middle truck 4 carrying the arc height measuring device 6, e.g. a potentiometer, and a rear truck 5. In a first step the track 1 is displaced into its correct position only at the locations corresponding to the fixed points F. The desired arc height values are marked on the sleepers such that with the truck 4 opposite a fixed point, say F 1 , the sleeper beneath the truck M will be marked on the inside of the curve with the desired arc height at the fixed point F 1 , and on the outside of the curve with the desired arc height at the point F 2 . These two values are set on potentiometers S 1 , S 2 , Fig. 7. The potentiometers S 1 , S 2  are interconnected by a potentiometer 9 the slider of which is driven in accordance with the movement of the trucks along the track 1 and the output at the slider of the potentiometer 9 corresponds to the desired arc height at the location of the chord 2 taking into account the desired arc heights of the two fixed points between which the chord 2 is situated and the position of the chord between these points. This output is compared with the actual arc height obtained for the potentiometer 6 and the result is indicated on an instrument D. The potentiometers S 1 , S 2  are thus set at each fixed point along the track in accordance with the arc height values marked on the sleepers and the track 1 is then displaced until a zero reading is given on the indicator D. Control lamps 8<SP>1</SP>, 8<SP>11</SP> are also provided and these light as soon as the set arc height coincides with the actual arc height measured by the potentiometer 6.

Abstract: 792,274. Coating with metals. WESTERN ELECTRIC CO., Inc. Nov. 8, 1955 [Nov. 16, 1954], No. 31883/55. Class 82(2) [Also in Group XXXVI] Boron and silicon are codeposited with carbon in a thin film on to a surface by bringing the surface into contact with a mixture, in the gaseous state, of compounds comprising chemically bound carbon, chemically bound silicon, and chemically bound boron as the only depositable elements while maintaining the surface at a temperature sufficient to cause the required deposition to take place. As shown, a non-conducting core, e.g. of a ceramic material, is fed downwardly from a guide 12 to a guide 13, the guides being separated by a space 18 of approximately 2 inches. Nitrogen may be fed through fittings 14 at the outer ends of the guides, and helium to the points 15 and 16 to prevent the coating gases from entering the guides. Beneath the zone 18 a tube 10 concentrically surrounds the lower guide and is connected to a supply of nitrogen saturated with boron trichloride and silicon tetrachloride. A jacket 21 surrounds the reaction zone and the tubes and has an inlet 22 for the supply of a carbonaceous gas, e.g. methane mixed with nitrogen, and an outlet 23 for the removal of waste products. The jacket is surrounded by an electric furnace to maintain a temperature of 1000-1400‹C. Cooling water may be supplied to the outer ends of the guides. The carbonaceous gas may be methane, ethane, propane, butane, benzene, toluene or xylene or partially halogenated hydrocarbons, the silicon compounds may be silanes halogen substituted silanes, and compounds containing carbon and silicon, e.g. methyl silicane, may also be used. Diborane, borane halides, boron trihalides, and mixed alkyl-aryl borines may be used as sources of boron. All gases supplied to the reaction chamber should be dry and free from oxygen. The ratio of the number of atoms of boron to carbon may be between 1 and 0.01 and the ratio of silicon atoms to carbon atoms may be between 3.00 and 0.01.

[Classes 51 (ii) and 55 (i)] In the production of hardened briquettes according to the method described in the parent Specification in which the briquettes are oxidized before being heated in an oven, transportable containers 2 are used for the oxidizing treatment, and are placed in a closed chamber 5 through which hot oxidizing gases pass upwards, the containers being then transported to the filling openings of the hardening oven 6 into which their contents are discharged. The containers 2, Fig. 4, each have a conical base 7 with perforations 10 which admit oxidizing gases, and a closure 9 supported from a bar 8. They have rims 19 which rest on ledges 20 in the compartments, and hot flue gases from passage 12 and air from pipe 18 are driven by fans 11, 16 respectively, and are mixed before entering the containers by passages 14 from below and passing through the charge and through draw-off flues leading to a chimney. After oxidation, a trolley 3 carries each container to a charging frame 27, which moves on rails 26 along the oven top, and is provided with a funnel 28 which is arranged over the charging opening 29. Distillates escape through an ascension pipe 31. The hardened briquettes are discharged into wagons 37 and quenched in a tower 37a. The oven is heated by gas from pipes 39, 39a, which lead to heating flues 40, the air passing in one direction from conduits 41, 42 into regenerators 43 having openings 44 into the flues 40, and in the other direction through conduits 41a, 42a into regenerators 43a.

The briquettes are hardened in a vertical oven, heated by flues 59, 59a, in the upper part 58 of which oven they are heated, being cooled in the lower part 58a before discharge. The heating gas is supplied from pipes 61, 62 and is mixed with preheated air from pipe 63, the waste gases passing to an upper passage 64, and through passage 65 to the distributing passage 64a of the other heating flue 59a where gas and preheated air are again burnt, the waste gases being drawn off down through the heating flues to a lower passage 66a leading to pipes 47. The chamber 58a is cooled by air drawn by a fan 48, and pipes 71, 70 through the zigzag cooling chambers 67, the heated air being passed for combustion or oxidation purposes through pipes 73, 72 respectively.
