Title: Apparatus for machining by spark erosion
IPC: B23H1/02
Filed: 1958-04-09
Abstract: 842,517. Cutting by spark erosion. ATELIERS DES CHARMILLES S.A. April 9, 1958 [April 10, 1957], No. 11183/58. Class 83 (4). A spark-erosion apparatus has an electrostatic accumulator 2 charged from a direct current source 1 and a saturable self-induction coil LS is connected in series in the discharge circuit and the latter has a coefficient of selfinduction which is sufficient relatively to its ohmic resistance to produce an oscillating discharge from the accumulator 2 when the coil 11 is saturated, whereby at the moment of discharge a reversal of voltage takes place in the discharge circuit such that the discharge current causes the coil 11 to become saturated and thus stop the current flow. The accumulator 2 may be a capacitor charged through a resistance R and inductance L. The coil LS has a main winding 11 and a biasing winding 7 fed from a D.C. source 8 through filter choke 25 and variable resistance 9. The biasing winding may be omitted. The coil may have a core formed by a winding of sheet iron or it may have a core of ferrite. The electrode 3 and workpiece 4 are immersed in an electrolyte or a dielectric fluid such as petrol. A rectifier 10 is connected across the spark gap to conduct when the electrode becomes positive. In another embodiment, Fig. 4 (not shown) the accumulator comprises a delay line and the rectifier 10 is replaced by a resistance; this resistance may be omitted when an electrolyte is used. The accumulator may alternatively comprise a condenser in series with two parallel oscillating circuits.

Title: Improvements in weft feeler mechanism for looms for weaving
IPC: D03D51/34
Filed: 1925-04-30
Abstract: 245,328. British Northrop Loom Co., Ltd., (Northrop Loom Co.). April 30, 1925. Addition to 234,265. Weft-feeler arrangements. - The spring-controlled feeler 21 is at times and for certain periods held forwards away from its feeling position by a spring-controlled detent lever 38 having a tooth 40 engaging a tooth 43 on the feeler, the lever 38 being periodically tripped, to enable the feeler to move to its feeling position, by a trip 69 on a ratchet wheel 46 driven by a pawl 68 pivoted to a block 65 on a rock shaft 54 having a slotted arm 57 actuated by a screw &c. 59 on the cam follower or weft hammer 55 actuated by a cam 63 on the low shaft 64. The trip 69 acts on an extension 42 on the lever 38. The pawl 68 makes its operative stroke when the cam follower is moving backwards and the shuttle is not in its box. After the weft feeler has been released, it is moved frontwards by a working supply of weft in the shuttle so far that an inclined part 44 on the tooth 43 acts on an inclined part 39 on the lever 38, thus raising the lever to enable it to engage this tooth 43 and retain the feeler in a forward inoperative position until the lever is again tripped by the trip 69. If, after the release of the weft feeler, there is not a working supply of weft in the shuttle, the feeler is not moved fowards sufficiently for the tooth 43 to raise the lever 38, so consequently the feeler thereafter acts to detect the state of exhaustion of the weft at each detecting beat up. The teeth 40, 43 may be relatively inclined so that after their engagement the feeler is moved laterally from the position shown in dotted lines in Fig. 2 to that shown in full lines, whereby the end portion of the feeler is moved beyond the reach of the weft on each detecting beat. Stops 71, 70 may limit the downward movements of the lever 38 and pawl 68.

Title: Improvements in or relating to thermiomic valve arrangements
IPC: H01J25/70
Filed: 1936-04-20
Abstract: 454,361. Thermionic valves. PINTSCH AKT.-GES., J., 71, Andreasstrasse, Berlin: April 20, 1936, No. 11333. Convention date, April 18, 1935. [Class 39 (i)] A valve for ultra-short wave use comprises a hollow resonating space bounded by conductive walls between the grid and the plate and a control space between grid and cathode coupled to the first space. In one form, Fig. 1, the grid 2 and plate 3 are prolonged to form a resonator space and an energy channel 4<1>, 8 to the aerial 6. The cathode leads comprise a wire 12 and a cylinder 11, and the cylinder 11 is coupled to the plate 3 by a short condenser 13. A cylinder 14, one quarter-wave long is attached to the lead 11 by a flange 15 and serves as a choke. The valve is sealed off by insulation between leads 11 and 12 and by seals 16, 17. The grid lead 19 is sealed through the lead 8 at 20. In a modification, the cylinder 11 is coupled to the resonating space by an annular flange carrying a short cylinder inside the plate 3. The cylinder 14 is coupled to the flange by a parallel flange and is sealed to the end of the plate 3. In another modification, Fig. 3, the outer resonating member 26 is closed at one end and the concentric cathode leads 28, 29 are taken out through a potential node. The lead 28 is prolonged to form a member 30 which, together with the lead 4<1>, forms a short-circuit condenser. The cathode is coupled to the plate by a condenser plate 33 secured to and spaced from the plate 3 by insulation 34. The coupling may instead be effected by making the member 30 continuous at its upper end with the member 4<1> which is insulated from the member 27 and by prolonging the member 27 into a cylinder between the members 30 and 4<1>. The grid may be closed at its lower end by a cap to which the filament bight is insulatingly connected. In another modification, the three electrodes are extended in each direction to form a quarter-wave short-circuiting condenser at the lower end and an aerial energy channel at the upper end, the cathode being connected to the plate by small condenser plates held on members passing through the grid. The shortcircuit condenser may be modified by the inclusion of a cylinder connected to the plate extension and arranged between the grid and cathode extensions, the coupling condenser plates being then dispensed with. Disc-shaped resonating spaces may be used with either method of coupling. The mode of operation of the valves is described in the Specification.
