Abstract: 1368553 Magnetic thread brakes KIJ ROSEN 3 Jan 1973 [3 Jan 1972] 406/73 Heading DID [Also in Division F2] A thread guide roller 3 consisting of two magnetizable soft iron discs 33, 34 is rotatably journaled and axially movable on an axle 4 and a permanent magnet 6 acts to attract the roller 3 so that one side thereof is drawn onto a circular friction surface 5 to decelerate the roller 3 and a thread 2 and wound around it. As shown, the magnet 6 is cylindrical, is surrounded by a coil spring 7 and both magnet 6 and spring 7 are screwed into a bore 8 of a sleeve 9 eccentrically disposed relative to the axle 4 which is located in the centre of friction surface 5: the magnet 6 is lacquered to prevent the coil spring 7 from slipping. The sleeve 9 is mounted in a hole 19 in a tab 17 of a support 14. The support 14 also includes a base plate 15 and a tab 16 which tab 16 mounts a preliminary brake 18 comprising a sphere (25) seated on a seat (26). A thread guide hook 30 is also mounted on the support plate 14. The thread 2 is conducted through the preliminary brake 18, round the roller 3 and about the guide hook 30 and in use frictional forces between the roller 3 and surface 5 decelerate the roller 3 and the thread 2. This braking action can be adjusted by screwing the magnet 6 into and out of bore 8. The roller 3 may be constructed symmetrically and the two side surfaces of discs 33, 34 may have varying degrees of roughness so that a different braking action may be obtained by reversing the roller. The sides of the roller may be coated to reduce the amount of wear or to vary the coefficient of friction, and the coating may be interchangeable.

Patent GB-1473091-A (GB)
IPC: C03B5/26
Filed: 1974-03-14
Abstract: 1473091 Internal resistance heating ELEMELT Ltd 14 March 1974 [4 Jan 1973] 486/73 Heading H5H A furnace for melting materials which are only conducting when molten, e.g. glass, alumina, sodium silicate or magnesium chloride comprises a furnace chamber having a bottom wall 12 and a peripheral wall 17, an inner electrode arrangement at or near the centre of the chamber and an outer electrode arrangement at or near the peripheral wall 17, an A.C. supply connected to the inner and outer electrode arrangements in such a way that current flows radially between the inner and outer electrode arrangements and the establishment of peripheral voltage gradients in the peripheral wall 17 is avoided, and means for diverting current from the bottom wall of the chamber. Such an arrangement permits the peripheral wall 17 to be formed of or lined with a material, e.g. 96% chromic ocide, 4% titanium oxide, which although chemically non-reactive, has too high an electrical conductivity to be used normally. As shown the outer electrode arrangement comprises angularly spaced electrodes 19a-19i and the inner electrode arrangement comprises a concentric array of electrodes 20a-20i. To divert current from the bottom wall 12 insulating blocks 21 which shroud the lower ends of the electrodes are provided. The blocks 21 are made of zirconium orthosilicate. The blocks cause the formation of a stagnant layer of glass in contact with the bottom wall and thus allow it to be formed of or lined with chromic oxide material. Alternatively, the diversion of current to the bottom wall may be prevented by a relatively poorly conducting lining on the bottom wall. Either or both electrode arrangements may be in the form of cylindrical electrodes, the outer cylindrical electrode forming the wall of the chamber and being composed of the chromic oxide material and the inner cylindrical electrode, also being formed of chromic oxide and forming the inner wall of an annular chamber. An intermediate concentric array of electrodes may be interposed between the inner and outer electrode arrays to enable the outer portion of the chamber, which is subjected to the greater heat loss, to be heated more than the inner portion of the chamber. An outlet for glass may be provided in the centre of the bottom wall or may extend radially between the electrode arrays. When a central outlet is provided it may be formed as a duct having an adjustable crosssection for forming fibres. The duct may be heated by current between an annular electrode about the duct exit and the inner electrode array. Current regulators may control the current between the inner and outer electrode arrays. Reference has been directed by the Comptroller to Specification 1,177,070.

Filed: 1956-01-09
Abstract: 807,375. Turning, milling, &c. machines. C.O.V.E.M.A. CONSTRUCTION ET VENTES DE MACHINES. Jan. 9, 1966 [Jan. 10, 1955], No. 665/56. Class 83 (3). A machine-tool having a vertically-slidable head carrying mechanism for driving the work or a tool such as a milling-cutter, and also for feeding a saddle, has an hydro-pneumatic unit for balancing and supporting the head on guides which are carried laterally of a lathe-like bed. The milling-cutter may be mounted in the headstock spindle, or on an arbor 57, Fig. 4, supported by the spindle and a vertically-adjustable outboard bearing 58. Graduated scales facilitate the adjustment of headstock and bearing. The headstock 22 is moved vertically on guides 23, 24 by a screw 92 attached thereto, co-operating with a nut driven by gearing in a box 20. Counterbalancing is by a plunger 122, Fig. 14, on the headstock, sliding in a fixed cylinder 117, open at the bottom and communicating with fluid 112 acted upon by compressed-air in a casing 111 attached to the machine bed. The air-pressure is adjusted, as by a hand pump, to suit the weight of the attachments on the headstock. Driving-gear and feed-motions.-The headstock-spindle 25, Figs. 3 and 4, is driven by a motor through a clutch and change-gear controlled at 32, 33. The spindle drives a feed-box 21 which drives, through a cardan-shaft 41, a further box 20 on the machine bed. Box 20 drives, through a clutch, the feed-screw 17, and also drives a feed-shaft 16, and has a wormdrive for the nut of the headstock-elevating- screw 92. The transverse feed-screw for slide 45 drives, through a clutch, a nut splined on the feed-screw for the milling-slide 60. Slide-rests.-The angularly-adjustable slide 60 is supported on surfaces 129-132, Fig. 9, on saddle 14 and is centred at 134. Locking in any angular position is effected by bolts in bosses 129-130 engaging an arcuate T-slot therein and drawn downwardly by tapered set-screws 138, Fig. 12, engaging wedge-shaped recesses in the bolts 136.

Title: Improvements in or relating to motion transmitting devices
IPC: F16H49/00
Filed: 1958-01-08
Abstract: 878,948. Screw-and-nut gearing. MUSSER, C. W. Jan. 8, 1958 [Jan. 9, 1957], No. 704/58. Addition to 790,171. Class 80 (3). A modification of the invention of the parent Specification consists in forming the two cooperating toothed gear members as screw-andnut members whereby the conversion of rotary motion into linear can be effected or vice versa. A screw 40, Figs. 1 and 2, co-operates with a nut portion 42 of a slightly larger diameter of a flexible-walled strain tube 41. The thread of the nut is of the same cross-section as the screw but of a different lead and only engages at certain points under the influence of a strain inducer 43 in the form of a ring with a lobed internal periphery fitting over the tube 41. If the strain inducer 43 is rotated, the point or points of thread engagement will progress around the screw and owing to the difference in the leads a relative axial movement will be produced. Alternatively, the input movement could be applied through the screw 40 or the tube 41 and the output derived from one or both of the other members. One of the threaded members may have no lead, the thread consisting of circular grooves. If the nut member is of sufficient diameter to clear the thread of the screw in the unstrained condition disconnection of the thread engagement can be effected when desired by releasing the strain inducer pressure. The device allows movement to be transmitted through the wall of a sealed container, the flexible tube 41 being incorporated in the said wall. The strain wave may be propogated mechanically as described or by means of a rotating electromagnetic field. The strain inducer may take the form of a lobed cam inside a flexible tube with an external thread co-operating with an internally screwed member. The flexible strain tube may be made of suitable metal such as steel, bronze, titanium or plastic material such as rubber, neoprene, nylon for moderate load devices. Fig. 25 shows the application of the device to an adjustable link, a strain inducer 203 acting on a flexible strain tube 195 being rotated manually or by an electric motor to vary the length of the link.
