Title: Method and device for electro-machining
Inventor: VOIGT GERHARD
IPC: B23H5/02
Filed: 1966-05-27
Abstract: <PICT:1100928/C6-C7/1> The ends of wires of a punched-card machine reading brush 1 are electro-machined by a process wherein metal is removed by electro-erosion and electrolytic machining to provide a contact surface lying at a specific angle to the longitudinal axis of the wires by moving them connected as an anode, e.g. received in slots (10, 11) machined in the annular extensions 35 of a work-holder 7-9 sliding against a carbon rod 19 connected to the positive pole of a D. C. source, across the surface of a rotating cast iron wheel 5 connected as a cathode, e.g. on a liner 4 mounted for rotation about a receiving member 3 with its contact ring 21 sliding against a carbon rod 20 connected to the negative pole of the D. C. source, and supplying a waterglass solution consisting of by weight 1 part waterglass to 8 parts water between the brushes 1 and the wheel 5, e.g. by passing the waterglass solution centrifugally up from an annular container 28 rotating with the liner 4, along the inner wall of a tapered sheet-metal ring 27 and through bores 26 or tubes (29, Fig. 5) in the wheel, and through slots between the wheel 5 and a cover-plate 31 with raised portions 32.  As shown, the member 3 secured to a mounting plate 2 receives, eccentrically to the wheel 5, a spindle 6, which carries the work-holder 7-9 and is driven through a reduction gear 12-18 from the rotating liner 4 driven by an electric motor 22; the reduction gear consists of a gear-wheel 12 in mesh with the toothed rim 25 of the liner 4, a pinion 13 mounted on a common shaft 18 and a planet-wheel gear 14-17. The D. C. voltage is 8-10 volts.

Title: Tool rotator for reciprocating hammer
Inventor: RICHARDS ARCHER WILLIAM
IPC: B25D11/12
Filed: 1951-10-15
Abstract: 713,018. Ratchet gearing. SYNTRON CO. Oct. 15, 1951, No. 24003/51. Class 80 (3) [Also in Group XXIII] A reciprocating member, such as the tool holder 37 of an electromagnetic percussive drill, is rotated step-by-step as it reciprocates by a frictional ratchet device comprising two oppositely-acting annular pawl members 50, 51 of rubber or the like held within non-rotatable cups 44, 45 so as to be alternately compressed and released against the faces of a flange 41 on the tool holder, the compression flexing the levers 62, Fig. 5, of the pawl members and imparting a rotation to the tool holder. The cups 44, 45 are secured together to give the pawls an initial compression determined by one or more spacing washers which may be removed when the rubber has acquired a permanent deformation. The cups are connected by two tie rods (not shown) to a plate 32 supporting a rubber member 30 slidable in a sleeve 34 and forming the upper stop for a magnetic piston 6 which is reciprocated by alternately energized coils 3, 4. A spring 33 urges to its uppermost position the movable frame comprising the plate 32, the tie rods and the cups 44, 45. When the piston 6 strikes the holder 37 the pawl 51 is compressed and is released by its own resilience, thereby compressing the pawl 50. Similarly, as the piston strikes the stop 30 the impact on the frame compresses the lower pawl 51 which is again released by its own resilience. The pawl 51 thus constitutes the main driving member of the ratchet gear and is formed with a heavier flange than the oppositely-acting pawl 50, which is operated by the reactions of the pawl 51 and serves principally to prevent back-running or oscillation of the flange 41. In a modification, Fig. 9 (not shown), the movable frame is dispensed with and a single rubber pawl member acts between the casing and the upper side of a flange on the tool holder, the under side of the flange being urged upwards by a spring whose lower end engages a thrust bearing in an extension of the casing. The levers 62 of each pawl member may have metallic inserts, and there may be eight levers each tapering towards the centre of the annulus so as to be triangular in plan view. The drill is powered by an alternating current supply which passes from input terminal 28 through a switch 14 in the handle to the centre 23 of a metal disc rectifier. The end plates of the rectifier are connected respectively to the coils 3, 4 which are thus alternately energized, the common return 26 being taken through the switch 14 to the second input terminal 27. In a modification, the piston 6 is replaced by a hammer piston reciprocated by a crank driven by an electric motor. It is stated that each pawl member may comprise flexible metal spring elements extending from a ring and engaging a knurled or shallow-toothed surface to constitute a positive ratchet gear.

Abstract: 979,495. Vehicle trainers. W. HELMORE. June 21, 1963 [June 21, 1962], No. 24014/62. Headings B7H and B7W. Apparatus for simulating movement of an aircraft or other vehicle comprises a harness and a chair, part of which chair is reciprocable by a ram, movement of the ram in one direction also causing movement of part of the harness towards the part of the chair. In the Figure the chair comprises a frame 2 adjustably supported on rails 1, and a trainee supporting portion 6 is attached to the rod 4a of a ram 4 fast to the frame 2. Shoulder straps 9 extend from the buckle 13 of a lap strap to a common junction point behind the trainee, and the strap ends are connected through adjustable springs 12 to a cable 8 running between fixed pulleys 10 and pulleys 7 fixed to portion 6. When the ram contracts, the pulleys 7 tension the cable 8 to apply a force to the trainee's shoulders. In similar fashion, the seat back may be tiltable backwards or forwards, the lap strap being tightened when the seat back is moved backwards. The shoulder straps, or a yoke on the trainee's shoulders, may be movable sideways. The supply of fluid to the various rams may be controlled by electrohydraulic servo systems, in response to movements of dummy controls by the trainee or instructor's controls, or in response to programmes such as to simulate the effects of buffeting, catapult launch, or arresting gear, or programmes synchronized with film or television visual displays.

Title: Improvements relating to electrical conductors insulated with polyesters
IPC: C09D5/25
Filed: 1955-08-19
Abstract: 775,082. Insulation of dynamo electric machine windings. GENERAL ELECTRIC CO. Aug. 19, 1955 [Dec. 10, 1954], No. 24036/55. Class 35. The windings of a dynamo-electric machine are insulated by coating them with a polyester synthetic resin which is the reaction product of (a) 25-56 equivalents per cent of terephthalic and/or isophthalic acid (or ester-forming derivatives thereof); (b) 15-46 equivalents per cent of ethylene glycol; and (c) 13-44 equivalents per cent of a saturated aliphatic polyhydric alcohol containing at least three hydroxyl groups, e.g. glycerine, 1:1 : 1 - trimethylol ethane, 1 : 1 : 1 - trimethylol propane, pentaerythritol, sorbitol, mannitol, diglycerol or dipentaerythritol. The polyesters per se are claimed in Specification 775,081, [Group IV (a)]. The coating is applied by passing the wire through the resin dissolved in a solvent (e.g. cresols, xylenols, polyhydroxy benzenes, petroleum hydrocarbons, xylenes or a mixture of polyalkyl benzene (known under the R.T.M. " Solvesso " 100 or 150), then through a die and then through an oven when the resin is cured on the wire; this process being repeated a number of times if necessary. After the last pass, the wire is wound on a reel. The polyester resins may be mixed with minor amounts of other resins, e.g. melamine-formaldehyde, epoxide, phenol - formaldehyde, aniline - formaldehyde, urea - formaldehyde, silicone, cellulose acetate, polyamide, vinyl, ethylene, styrene or butadiene-styrene resins. Many examples are given which describe the coating of round or rectangular copper, aluminium or nickel-plated copper wires and which also give details of certain physical characteristics of the enamelled wires.

Title: Improvements in or relating to the electrical treatment of mineral and other material for separating different constituents thereof from one another
IPC: B03C1/253
Filed: 1934-08-21
Abstract: 426,860. Magnetic separators. MORDEY, W. M., 82, Victoria Street, London. Aug. 21, 1934, No. 24095. [Class 72] In a magnetic separator provided with a multiphase alternating current system, the stream of material to be treated in a finely divided dry condition or the form of pulp is caused to pass through a path arranged longitudinally of, and adjacent to, the longitudinal and parallel portions of elongated loop-shaped windings forming part of the multiphase system so that the material responsive to the action of the field is swept to one side of the path and separated from the material that is not responsive to the field, a longitudinal portion of each winding being arranged between the longitudinal portions of an adjacent winding and separated therefrom only by an inert non- conducting non-magnetic medium. The material to be treated is fed by a hopper 6 into a launder 3 of non-magnetic material and arranged over elongated loop-shaped windings 1, 2, arranged as shown and separated from each other by air or wood. The responsive matter will move toward the side 3b of the launder and will leave the launder by a shoot 4, the non-responsive matter gravitating to the side 3b and leaving by the shoot 5. The launder 3 may be vibrated, agitated or jogged e.g. by an eccentric 8<a> fixed on a shaft 8, and may be inclined. In a modification, Fig. 5, in which two streams of material are caused to move simultaneously through the two oppositely moving side portion of the multiphase field, a second launder 3a is arranged below the windings 1, 2 and material is fed thereto by a shoot 6<a> at the same time as another stream of material is fed to the launder 3 by the shoot 6. The separated portions of material leave the launder 3<a> by shoots 4<a>, 5<a>. In a second modification, Fig. 7, the material is fed by shoots 6, 6<a> to opposite sides of the windings 1, 2 arranged vertically, the shoots having inclined outlets so that the material is spread over the surfaces of the casing 9 enclosing the windings. The separated responsive material is kept apart from the non-responsive material by plates 9<a>. In another modification the material may be fed on to a travelling belt enclosing the windings instead of the launder 3. The windings in this form or in the other separators referred to may also be arranged that two laterally and oppositely moving fields are produced so that the responsive material is moved to both sides of the launder or belt the non-responsive material passing down the middle. Specification 165,822, [Class 72], is referred to.
