Filed: 1961-05-31
Abstract: 934,557. Electrolytically removing material. GENERAL ELECTRIC CO. May 31, 1961, No. 19644/61. Class 41. In electrolytically removing material from an electrically conductive workpiece, such as in producing passages of regular or irregular shapes or in contouring surfaces, the current is periodically reversed in order to lessen sludge deposits in the cavity being produced, the periodical reversing being biased so that the current used for metal removal is greater than that for sludge removal. Periodically reversed D.C. or A.C. may be used and frequencies of reversal may be up to and including ultrasonics. The electrodes may be hollow and insulated at its outer surface only, Fig. 3, or be insulated at both its inner and outer surfaces, Fig. 5. Alternatively, it may be solid, Fig. 4, or may comprise a wire 52a, Fig. 9, within a non- conductive tube 53. Fig. 3 shows electrolyte supplied at 31 through electrode 30, whereas Figs. 4 and 7 show the electrolyte supplied externally at 39. Fig. 12 shows an arrangement where electrolyte is fed from a supply 74 to an electrode 30 via a pump 75, filter 83, reservoir 72 and flow control 85. From a workpiece 36 it is returned to the supply 74 via a tank 82 and pump 77. Movement of the electrode with its reservoir 72 by a motion apparatus is controlled at 81 as is also the electrolyte flow and the current and its reversal. A guidance fixture, Fig. 11 (not shown), may be used whereby holes may be formed parallel or at an angle to one another. One example refers to forming holes in turbine blades. A Ti tube electrode coated with polyethylene and an electrode comprising Ag, Pt or Au deposited within a non-conductive tube of e.g. ceramic, plastic, wood or rubber are described. Current densities are used such that sparking does not occur, e.g. 3,846 to 10,769 amps/in.<SP>2</SP>, and it is stated that by increasing pressure on the electrolyte or decreasing temperature the sparking point is delayed. The electrolyte may be 25% by weight aq. H 2 SO 4 .

Abstract: 1,039,124. Feeding interlocked sleeves. HELLERMANN Ltd. Dec. 13, 1963 [Dec. 13, 1962], No. 19703/64. Divided out of 1,039,122. Heading B8S. [Also in Division H1] A stack of interlocked sleeves is dropped into the inside of transparent tube 11 mounted on frame 1. The column of sleeves rests on the top of pivoted jaws 12. In operation, hand tool 21 (not shown) is thrust horizontally through aperture 2 to engage with and move backwards element 7. This causes lever 8 to pivot about 9; and the pivoting of lever 8 effects two actions: it causes element 26 to engage and agitate the tube 11 to free the sleeves within, and it causes, by engagement at 13, the opening of jaws 12 so that the column of sleeves falls down on to bars 14. At the subsequent removal of the tool 21 from aperture 2 the jaws 12 close to grip the next sleeve to the lowest. The bottom sleeve thus exposed is removed when the operator thrusts tool 21 between bars 14 upwards to engage the sleeve, to detach it from the stack, and then to pull it downwards. The tool is then employed to slip the sleeve on to an electric conductor.

Abstract: 571,866. Ratchet gearing. LANDIS & GYR SOC. ANON. Nov. 29, 1943, No. 19921. Convention date, Dec. 3, 1942. [Class 80 (iii)] [Also in Group XXXVII] Relates to resonance spring ratchet drives for the remote control of switches, clocks, tariff apparatus and automatic staircase switches, wherein the resonance spring acts upon a toothed disc, and has for its object the obviating or minimizing of the injurious effect of the vibrating driver on the fine teeth of the disc. Currents of different frequencies may be passed through the magnet 1 to excite one or other of resonance tongues 3, 4, the free ends of which have spring blades 5, 6 adapted to drive toothed discs 7, 8. These discs are mounted freely on a shaft 9, are prevented from moving backward by brake springs 10, 11, and carry driving pins 12, 13 adapted to engage a driver 14 fast on the shaft 9 which can be moved axially under the action of a cam 26 and blade spring 27 to bring this driver into the path of one or other of the pins. The shaft 19 is connected by gearing 15 ... 19 with cams 20 adapted to actuate, for example, switch blades 21, 22, and through further gearing 24, 25 with the cylindrical cam-shaped edge 26. After a drive by one of the tongues 3 or 4 sufficient to complete the actuation of the switch, the cam 26 is brought to a position such that the shaft 19 is moved axially to bring the driver 14 in the path of the other pin for actuation, when desired, by the other tongue. At the same time any further rotation of the shaft 9, the cams 20 and cam 26 is interrupted although the driving disc that has been in use may be still further rotated for a time. The driver 14 may have a number of arms or be in the form of a double-edged blade associated with opposed crown teeth on the discs.
