Title: Improvements in continuously adjustable ohmic resistances for electric currents
IPC: H01C10/26
Filed: 1938-07-27
Abstract: 516,852. Variable resistances. ZEISS C. [Firm of]. July 27, 1938, No. 22298. Convention date, Aug. 14, 1937. [Class 37] Resistance wire or strip is wound from an insulating to a conducting drum, the connecting leads being attached directly to the ends of the resistance wire, As shown in Fig. 1, the resistance wire c is wound from an insulating drum a to a metal drum b, so that the part of the wire on the drum b is short-circuited. Contact pressure is provided by a wire g kept under tension by springs i, i<1> fixed to the drum b, a. A scale e indicates the resistance in the circuit. Connections are made through spiral springs f, f<1>, soldered to the axles k, k' and connected to the ends of the resistance wire c. A resistance for use with apotentiometer connection is shown in Fig. 2, in which the resistance wire c is wound from a metal drum b over an insulating drum a to a metal drum b' coaxial with drum b. Leads f<1>, f<11> are attached to the ends of the resistance, an intermediate point h being connected through the axle k and spiral spring f. Rotation of the drums causes an equal length of resistance wire to be wound on one conducting drum and off the other so that the total lengh of resistance wire in circuit remains constant but is divided into variable parts by the tapping points h. Alternatively the resistance wire may be wound from an insulating drum or other carrying body, over a carrying body of conductive material, to a third insutating carrying body, the variable potentiometer tapping being constituted by the second carrying body. Non-linear dependence of resistance variation with angle of rotation may be secured by making one or more of the carrying drums not rotation-symmetrical, e.g., in the form of an Archimedean spiral. The Specification as open to inspection under Sect. 91 comprises also the following constructions. A taut wire c, Fig. 1 (Cancelled) is pressed by a slider d against a convex metal surface b. Fig. 3 (Cancelled) shows a construction in which resistance wire c is wound from an insulating drum a to a metal drum b, connection being made to the axles k, k<1> by spiral springs f, f<1>, the axle k being insulated by a brush m. Fig. 5 (Cancelled) shows a modification with a potentiometer connection. The resistance wire c is wound from an insulating drum a over a metal drum b on to an insulating drum a<1>. Similar constructions may be employed for variable inductances. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in cutting machines for fabrics
IPC: D06C13/00
Filed: 1962-06-08
Abstract: 940,416. Finishing fabrics. SUCCESSEURS DE GROSSELIN & DEHAITRE. June 8,1962 [June 9, 1961], No. 22331/62. Heading D1S. A machine for cutting or scraping pile fabrics comprises a bed 11 over which the fabric passes against a cutting cylinder 3, and a support 13 for the bed arranged to be capable of carrying out a pivotal movement about an axis parallel to the axis of the cutting cylinder between a working position in which the bed is located in immediate proximity to the cutting cylinder and a position of withdrawal in which the bed is at a distance from the cutting cylinder. The support 13 carrying the bed 11 is mounted on the end of a shaft 14 which is mounted in a bearing 15 and carries a two-position clutch 41 for connecting the shaft to an arm 39. A connecting rod 37 joins the arm 39 to an eccentric 34 arranged to be driven by gearing 33 from an electric brake motor 32. The fabric 10 is fed over rollers to the bed 11 and cutting cylinder 3 and in the event of a thickness, such as a seam, entering the machine, an electrical contact 60 is operated by the seam and actuates a switchgear unit 70 to energize the motor 32 which rotates the eccentric 34 to swing the bed away from the cutting cylinder, the motor being stopped by a limit switch 66 actuated by a cam 63 secured to the eccentric. After a predetermined time sufficient for the seam to pass the cutting cylinder, the motor is re-energized to rotate the eccentric and return the support and bed to their operative positions, the motor again being stopped by the cam actuating a limit switch 65. The support is resiliently urged to its operative position, which is determined by its engagement with a surface on a locking pin 17, by a spring 61 on the connecting rod 37. The bed 11 consists of a single ridge and it can be replaced by a bed 12 having two ridges between which the cutting is effected by axially shifting the locking pin to a position clear of the support 13, disengaging the clutch 41, rotating the support 13 through 180 degrees and re-engaging the clutch and returning the locking pin to its original position. The bed 11 may be reciprocated in slideways 71 by a rack-and-pinion mechanism 72,73 connected to a chain-driven wheel 74. The material after passing the cylinder 3 passes to a similar bed 2 and cutting cylinder 4 before passing to a folding device 6.

The aperture may be metal-lined. The indium plug may be covered by a metal plate 9. An electrode 10, forming together with a wall electrode 13 part of an electron lens, is mounted in tube 1 similarly to electrode 4, and is connected to indium or indium-containing plugs in aperture 12. The apertures 8, 12 may be formed by sandblasting, and their walls covered by a thin layer of metal, preferably nickel. The electrodes are held in position with lugs thereon in contact with indium-containing material in the apertures. The tube is de-gassed at high temperature which melts the material which forms a seal when cooled. The tube may be formed with a shoulder to locate an electrode.

Abstract: 1491477 Steering vehicles COVENTRY CLIMAX ENGINES Ltd 20 May 1975 [21 May 1974] 22639/74 Heading B7H A vehicle such as an industrial track comprises a wheel carrier 12 on which a ground wheel 11 is rotatably mounted and to which an end of a first linkage 14 is rigidly secured; a second linkage 16 pivoted at joint 15 at one end to the other end of linkage 14 and at joint 20 at its other end to an end of a drop arm 21, with a fulcrum 19 coupling the second linkage 16 at a point intermediate its ends to the vehicle chassis 18; and an eccentric means 24 coupling the drop arm 21 to a steering shaft 22 so that rotation of the shaft 22 is converted into angular motion of the drop arm and rotation of the second linkage about the fulcrum 19 to effect steering of the vehicle. The eccentric means 24 comprises a further shaft 26 coupled to the steering shaft 22 by a universal joint 23 and incorporating an eccentric lobe 27 which is received in a bore 29 of a toothed chain wheel 28. Rollers 31 secured to housing 25 are received in openings 30 of the wheel 28 which is thus constrained to execute displacement by the lobe 27 in a circular path without any substantial angular rotation of the wheel 28 about its own axis. The teeth of wheel 28 engage an internally toothed member, formed by the links of a chain 35 secured to a carrier 24, which is fixed to a sleeve 33 in which the drop arm 21 is slidably received. The number of links of chain 35, say thirty, exceed the number of teeth on the wheel 28, say twenty-seven, so that their interengagement serves as a reduction gearing transmitting shaft rotation to the drop arm.
