Title: Improvements in spark discharge machining apparatus
IPC: B23H1/02
Filed: 1955-01-07
Abstract: 800,449. Cutting by spark discharge. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Jan. 7, 1955 [Jan. 12, 1954], No. 601/55. Class 83 (4). In apparatus for machining a workpiece 5 by sparks discharged between it and a tool electrode 4, the discharge current is supplied from an alternating current source 1 through a rectifying system including rectifier gas tubes, such as thyratron tubes 3a, 3b, 3c whose grids are subjected to a negative bias to thereby interrupt the discharge current when the latter exceeds a predetermined value. The discharge circuit includes a condenser 6, a self-inductance coil 7 and a resistance 8. An electromagnet relay having its coil 9 in series with an adjustable resistance 10 is connected in shunt with the resistance 8 and the grids of the thyratron tubes are each connected through a resistance 11a, 11b and 11c and a common resistance 12, which has a condenser 13 in shunt therewith, to the common point M of the cathodes. When the discharge current reaches the value that causes arcing between the electrode and workpiece, or a suitable fraction such as 0.8 of that value, the armature 9a of the coil 9 is pulled inwards and a battery 14 causes a negative bias on the tube grids which interrupts the flow of discharge current. When the current falls the armature 9a is released and normal sparking is resumed, the condenser 13 serving to prevent vibration of the armature. In a modification, Fig. 2 (not shown), the relay 9, 9a is replaced by a thyratron tube connected to an alternating network and acting both as a rectifier and a relay, the tube grid being biased by the voltage drop across resistance 8 through further resistances and a potentiometer so that it is conductive and causes a negative bias on the grids of tubes 3a, 3b and 3c when the predetermined discharge current is exceeded. In a further modification, Fig. 3 (not shown), the relay coil 9 is connected so that it is subjected to the spark gap voltage opposed by a voltage from a separate battery acting across a resistance adjusted so that the armature 9a is operated when the mean voltage across the spark gap falls below a critical value representing the change from sparking to arcing.

Title: Improvements in Street and Station Indicators.
Inventor: CLARK WILLIAM
IPC: B61D41/00
Filed: 1918-01-14
Abstract: 115,394. Clark, W., (Robinson, F. B.). Jan. 14, 1918. Reel and web apparatus.- In a stopping-place indicator for vehicles bearing the names on an intermittingly moved web passing from one roller to another, the mechanism is operated by pneumatic means controlled electro - magnetically. The casing containing the web and rollers is provided with two windows, only one being in use at a time. The web bears names on both sides, but in reverse order. At the end of a run, the casing is rotated to bring the other window into view exhibiting the names in reverse order on the other side of the web for the return journey. The web 37 bearing the names passes between rollers 34, 35 mounted in a casing 30 which can be rotated about central pivots 33 and has two windows 31, 32 near the ends and on opposite sides. As described, arrangement is made to give intermittent drive to the roller which is uppermost. For this purpose, the axles 34<x>, 35<x> are made slidable and adapted to engage a clutch member 36<c> on a shaft 36. A cylinder 14, the piston of which carries a rack 18, is put in communication with a compressed air supply pipe 15 or exhaust 16 according to the position of the piston valve 13. The vehicle carries an insulated shoe contact adapted to co-operate with stud contacts placed along the track in pairs, one of each pair being placed before, and the other after, the stopping place, &c. Contact with the first stud energizes electro-magnets which move the valve 13 to admit air to the cylinder, close a hold-on circuit to retain the valve against pressure of a returning spring 65 after the shoe has left the stud, and prepare the circuit of a releasing magnet which is energized when the shoe engages the second stud, so that the valve is then returned by the spring 65. The rack 18, which engages a pinion 23, is thus raised just before reaching the stopping place, and falls after leaving it. The reciprocations of the rack are communicated from the pinion 23 through uni-directional clutches, (not shown), to two bevel wheels 25 (one shown) engaging, at opposite ends of a diameter, a wheel 26 on the shaft 36, so that the clutch member 36<c>, and the roller in engagement therewith, are rotated intermittingly in one direction. The first movement exhibits the desired name, the second exhibits a blank portion of the web which remains in view until just before the next stopping place is reached. In the raised position of the rack, an insulated projection 20 closes spring contacts, (not shown), in circuit with lamps for illuminating the name being exhibited. For the return journey, the axle 34<x> is disengaged from the clutch member 36<c>, the casing is rotated to bring the window 32 into use with the roller 35 uppermost, and the axle 35<x> is engaged with the member 36<c>. A circuit diagram is given.

Filed: 1949-01-12
Abstract: 656,826. Rotary compressors. RONNOCO EXPORT DEVELOPMENT CO., Ltd. Jan. 12, 1949, No. 858. [Class 110(ii)] [Also inGroup XXIV] A sliding-vane compressor has a rotor 8 with a transverse pin 10 in a slot 12, free to move axially between end walls 13,16 and rockable on a spherical driving end of a shaft 7. The ingoing air passes through a filter 19 and channel 20 leading to an inlet 14 and is discharged through a port 15, duct 26 and filter 28 where entrained oil is separated out, the cleaned air being forced out to a line 29. Oil is supplied to channel 20 by suction through a duct 21 from a wick 22 immersed in an oil well 23. Some air is trapped by the vanes 9 beyond the delivery port 15 and used to force oil between the rotor ends and the end walls 13, 16 and also past the vanes into their slots. For rotor balancing purposes a recess 17, in the wall 16, matches the shape of the exhaust port which it faces. A second inlet port 14<SP>1</SP>, connected to the channel 20, ensures that lubricant passes to the remote end of the rotor. Screws 30 clamp the wall 16, casing 32, wall 13 and parts 33, 34 forming the oil well, together. A fan 36 driven by the motor 3 supplies cooling air between vanes 35 on the compressor casing. The Specification states that the rotor is driven at 10,000 r.p.m. and supplies air at a pressure of 25 lbs. per square inch.
