Title: Improvements in or relating to bonds for electric cables
Inventor: NEWMAN WALTER
IPC: H01R4/64
Filed: 1960-02-12
Abstract: 926,676. Cable couplings. HEPWORTH IRON CO. Ltd. Feb. 8, 1961 [Feb. 12, 1960], No. 4984/60. Class 38 (1). An armour or outer conductor bond is formed by doubling over a tinned or galvanized, flexible steel strip 1 (Fig. 4), looping it on to one side of an aperture 5 (Fig. 6) in a buckle 6 and passing the free ends around the cable and back through the buckle aperture 5. The doubled strip is then tightened and the free ends bent over the other side of the buckle aperture and finally hammered down on to the buckle. The buckle may have a lug portion for crimping on to a bridging member on earthing means, or the buckle may be replaced by, or used in combination with, an apertured bridging member as described in Specification 926,149. Electrical contact may be improved by placing metal braid around the cable strands under the strip, while deformation of the cable core may be prevented by stiff metal split-ring 9. Specification 794,734 also is referred to.

Title: Improvements in push-pull electric selector switches
IPC: H01H25/06
Filed: 1948-02-20
Abstract: 649,822. Press-button retractive switches; switches held set and freed mechanically. ARROW ELECTRIC SWITCHES, Ltd. Feb. 20, 1948, No. 5040. Convention date, Feb. 5, 1945. [Class 38(v)] A switch operating shaft is rotatable to select a desired set of contacts only after the operating shaft has been moved axially to open power-line circuits and without selecting other undesired control circuits. The power circuits are controlled by movable contacts 34, 46, cooperating, respectively, with fixed contacts 32a, 48. Contact bar 34 is mounted on a sleeve 36, slidable on the shaft 20, and is urged against a flange on the sleeve by a spring 38, the contacts 32a, 34, normally being open, as shown, a spring 44 compressed between sleeve 36 and the contact bar 46, which is also slidable on shaft 20, normally closing contacts 46, 48. If the shaft 20 is pushed to the right, the bar 46 is moved by a shoulder 20a on the shaft so as to open contacts 46, 48, the contacts 32a. 34, remaining open. If, however, the shaft is pulled to the left, a sleeve 40 thereon moves contacts 34 into engagement with contacts 32a, so that both power circuits are closed. In either case, the spring 44 restores the contacts to normal when the shaft is released. The control contacts are arranged in bases B, any number of which may be used. Each base contains two spring: contacts 54c, Fig. 13, normally urged into engagement with fixed contacts 52 by springs 50a, the contacts 54c being fixed at 54d to a terminal bar 56. The contacts 54c are operated by face cams which are prevented from axial movement on shaft 20 by flanges 66 which engage in recesses formed between adjacent bases B. The cams are mounted on a square sleeve 21 on the shaft 20, the sleeve 21 only being rotatable by the shaft when the latter has been moved to the right. Fig. 2. This coupling is made by a key 96, Fig. 15, fixed to shaft 20, and having wings 96w which move into slots 95 in a member 84 fixed on the end of sleeve 21. The member 84 carries a number of spring-pressed balls 80 which co-operate with depressions in a fixed plate 88 to provide a locating device for the switch. The wings 96w have one or more extensions 96x which, in the normal and pulled positions of the shaft, engage between projections 102 on a fixed member 100 so as to prevent operation of contacts 54c except in the pushed position of the shaft, the amount of rotation of the shaft being limited by an adjustable stop 112 and a fixed stop 104. A handle (not shown) on the shaft may have an arrow or other indicator thereon.
Patent GB-1133730-A (GB)
Title: Improvements relating to the unwinding and winding of yarn bands and webs of material
IPC: B65H59/38
Filed: 1966-02-04
Abstract: 1,133,730. Automatic tension control. J.P. BEMBERG A.G. Feb.4, 1966 [Feb. 4, 1965], No. 5040/66. Heading G3R. [Also in Division H2] In an arrangement for maintaining constant yarn tension, winding unit 1 is driven by motor 4, unwinding unit 5 being coupled to braking motor 9 through slip coupling 8 which is energized through resistor 10 varied in accordance with the material being unwound. The motors 4, 9, are supplied through rectifiers 19, 20 from transformer 15 having tap 16 driven by pilot motor 14, the motor 9 being driven in a direction to oppose the unwinding operation. At the limiting positions of the tap 16, standstill voltage is provided for either the motors 4 or 9 so as to maintain the yarn tension constant under these conditions. When the drive is switched off, the winding and unwinding units are held by brakes 2, 6. In another arrangement, the clutch 8 is energized through a potentiometer for setting the optimum yarn tension for different sizes of yarn. The diameter of the material being wound is sensed to control the motor 4 for constant winding speed, the motors 4, 9, being supplied through magnetic amplifiers or silicon controlled rectifiers. In a further embodiment, several take-off beams are each coupled through an eddy-current clutch to a braking motor, the several braking motors being in parallel across the output of a power amplifier. In a drive system for warping machines, all the unwinding units are served by one braking motor of the three-phase commutator type adapted for brush-shifting. A similar motor drives the winding unit and has a controller in common with the braking motor. The winding and unwinding units may be associated with squirrel-cage induction motors with a continuously variable speed transmission between each motor and the driving or driven part. Speed may be regulated by means of static frequency converters.

Abstract: 840,486. Magnetic record apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 18, 1958 [Feb. 26, 1957], No. 5297/58. Class 40 (2). [Also in Group XXXIV] In a braking device for braking tape recorder reels or the like, a leaf-spring 2 provided with a braking surface 3 is disposed against a braking drum; the upper surface of which acts as a supporting surface for a tape reel (not shown), the leaf-spring 2 being mounted on a support 4, 5 pivoted at 7 to a carrier plate, the arrangement being such that when the support is limited to a first position by a stop-member 11 controlled by a control-knob, the leaf-spring does not make braking contact with the drum whereas when the support is limited to a second position and the reel is rotating in a given sense, the frictional force arising out of contact between the leafspring and the drum acts in the same direction as the biasing force created by spring 8 to brake the drum. Fig. 4 illustrates brakes of the above description arranged in relation to two reels 14 and 15 of a tape recorder. The braking devices are so arranged at both reels as to avoid an unwinding of the tape 16 from the reels. Upon starting of the reels the driving-gear is coupled by means of a control-rod to the reel on to which the tape is to be wound and the brakes are disconnected by means of the mechanical linkage device connected to the control knob. Upon disconnection of the driving gear the two brakes are so connected whereby only that one functions which affects the unwinding reel while the other one is retained by the tension of the tape.

Title: Improvements in or relating to fuel elements for nuclear reactors
Inventor: STOHR JACQUES ANDRE
IPC: G21C3/04
Filed: 1963-02-11
Abstract: 980, 298. Nuclear fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 11, 1963 [Feb. 9, 1962], No. 5470/63. Heading G6C. A nuclear fuel element comprises an externally sheathed tubular fuel rod which has a crosssection having a cruciform or star-shaped outer perimeter and a circular inner perimeter, the arms of the star being equiangularly spaced and the tips of the arms of the star being joined by curves having a mean radius which is large relatively to the radius of curvature of said tips. Fig. 3 shows the cross-section of a fuel rod 4 with three arms, superimposed on that of a conventional tubular rod 1, the cross-sections having equal areas. The fuel rod 4 is seen to have a much greater surface area and a smaller minimum thickness than the rod 1. The radius R 3  of the concave parts must be large to facilitate the circulation of the coolant fluid and for a three-armed cross-section is preferably of the order of the radius R 5  of an imaginary circumscribed circle but for a larger number of arms the radius R 3  decreases, while remaining at least equal to 0. 2 R 5 . When the rod has no inner sheath, the inner cavity may be filled with gas or with a refractory material, especially when the number of arms does not exceed six, so as to help the rod to resist crushing. Beyond six arms, it is preferable to provide a circulation of coolant fluid in the cavity. The arms of the cross-section need not necessarily be of equal length. The outer surface of the rod may be provided with a mechanically applied sheath, as shown in Fig. 4 in the case of a four-armed rod, by slipping the rod 5 into a cylindrical sheath 6 of a flexible material of low neutron absorption, e.g. aluminium, magnesium or magnesium alloy. The sheath is then applied by chucks 7 or by the pressure of a liquid at a suitable temperature on the rod. The rod preferably has peripheral grooves or ribs on which the sheath is pressed. Alternatively, the sheath may be preformed before assembly and applied by means of thermopneumatic processes or under high hydraulic pressure. The sheath may be fixed to the rod by direct metallurgic joining or by the interposition of an appropriate intermediary material.

Title: Process for the conversion of olefins into liquid polymers
IPC: C07C9/16
Filed: 1937-02-25
Abstract: Mixed polymers of iso- and normal olefines are produced by subjecting a mixture of 4 carbon atom olefines with or without paraffins to the action of a catalyst comprising a phosphoric acid at about 135-163 DEG  C., and 30-44 atmos. for a contact time of approximately 250-350 secs.  Preferably, solid catalysts made by calcining a mixture of a phosphoric acid and an adsorbent as described in Specifications 437,188 and 464,671 are used.  The temperature and pressure conditions correspond to the critical values for the mixtures employed.  Liquid butane-butene fractions at the necessary temperature and pressure are passed down through beds of the catalyst and the products separated into polymers, which may be hydrogenated to iso-octanes of high anti-knock value, and C4 hydrocarbons which may be dehydrogenated and recycled.  In an example, a solid catalyst containing pyrophosphoric acid is used at 154 DEG  C., and 37,5 atmos. with a contact time of 260 secs.
