Title: Improvements in tufting machines
Inventor: ELLISON RONALD
IPC: D05C15/18
Filed: 1964-09-07
Abstract: 1,060,251. Tufting machines. ELLISON TUFTING MACHINERY Ltd. Nov. 30, 1964 [Sept. 7, 1964], No. 36556/64. Heading D1G. A multi-needle tufting machine comprises means for feeding yarn at constant speed to each needle, and a plurality of yarn tensioners each adapted to act on an individual yarn or on a plurality of yarns between the yarn supply and the yarn-feeding means, the tensioners being controlled by a patterning device to produce normal pile with normal tension, and short loop pile with increased tension to cause slipping of the yarn with respect to the yarnfeeding means. The yarns pass over a plate S positioned between the source of supply and a pair of spacedapart constant-speed feed rollers 41, 42, the axis of roller 42 being displaceable in a slot 43 to vary the bight of the yarn thereon. Tension is applied to the yarns by comprising the latter between plate S and the feet carried by the piston rods of respective pneumatic cylinders T, the supply of compressed air to which is controlled by a pattern drum. The application of pressure to a yarn or group of yarns causes slipping on the feed rollers to produce short tufts. Each cylinder may be selectively connected to alternative sources of pressure for producing their heights of tufts. Alternatively a second tensioner may be provided for each yarn or group of yarns.

Title: Improvements in apparatus for controlling electric currents

Abstract: 862,178. Superconductive relays. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 2, 1957 [Nov. 30, 1956], No. 37471/57. Class 40 (9). [Also in Group XXXVI] Apparatus for controlling electric current comprises a super-conducting element through which the current is passed, means to apply a control magnetic field to the superconductor, and screening means to restrict the magnetic field. Fig. 2 shows a gating device in which the controlled current is passed between terminals 28 and 30 through a layer 26 of material such as tantalum (if desired with an addition of high resistance material), or an alloy of tin and lead which may be rendered superconducting. A control coil 32 of wire or a spirally cut coating of niobium, lead or other " hard " superconducting material (i.e. having a high value critical magnetic field) surrounds layer 26, the control current through this coil being variable to provide a magnetic field strength above and below the critical value of layer 26 to switch this layer between its normal and superconducting conditions. A layer of insulation 24 separates layer 26 from a layer 22 which is also of " hard " superconducting material and in its superconducting state acts as a screen to reduce the volume of the magnetic field. The whole is maintained between 2 and 5 K., for example by use of liquid helium. In operation, coil 32 and layer 22 remain in the superconducting state. Layer 22 may be self-supporting, or a hollow or solid core 20 of copper, tungsten or insulating material may be provided. Fig. 3 shows a modification in which a similar structure is in flat form instead of cylindrical, the control current being passed through strip 48 which is magnetically coupled to the switched conductor strip 44. In a further modification, the control strip 48 is formed so as to cross strip 44 at a plurality of points to increase the magnetic coupling. The switched conductor may be formed with longitudinal apertures to increase its normal resistance. The arrangement provides a device for control switching or storage purposes with a small time constant and providing current gain. A bi-stable circuit may be provided by interconnecting the control and switched conductor elements of two such devices.

Abstract: 885,390. Coin testing. BATEMAN, K. C., and STEDMAN, J. J. Nov. 5, 1959, No. 37559/59. Class 27. A device for testing several properties of a coin includes a single pivoted member 37 for checking the thickness of a coin inside the rim, the member 37 being fitted late in the series of tests so that it is not subjected to wear by coins rejected in earlier tests and is not affected by variable forces imparted to the coin during insertion. A clearing wall 5 is hinged to a main plate 1 by a spring 6 and balls 7 and an inclined runner 9 is secured to the main plate; spacers 11 provide a gap between the runner and clearing wall for the rejection of too-thin coins and an adjustable needle point may be provided on the plate or wall for trapping too-thick coins. The coin, after insertion in a slot 17, falls between a guard 18 to the runner and passes an arm 19 weighted by a slug 20 and having a pin 21 which will arrest a washer, Coins too small in diameter lean outwardly past the bottom edge of an adjustable plate 29 and against a barrier 31 and are caught by a finger at the end of the barrier. After passing a permanent magnet which will retain steel slugs, the leading edge of the coin strikes a trigger 40 of the member 37 and pivots it so that a sear 39 at the other end engages just within the rim of the coin; if the thickness is correct, the trigger is pushed completely aside and the coin acting on the sear can continue the rotation of the member 37 until the coin is clear. If the coin is too thick, the member 37 jams on the coin before the trigger is clear and the coin is trapped. A bracket 41 for the bearings of the member 37 can be distorted by a screw to provide fine adjustment of the member. A bias weight 45 is provided on the member and an adjustable stop 46 fixes its rest position. Clearing coins.-Trapped coins are released on pressing a button 12 having a conical face 13 abutting an extension 15 of the clearing wall. A non-magnetic strip secured to the wall in front of the magnet pushes the slug away from the magnet. Released coins or slugs fall to a reject shoot 23.

Title: Method of controlling mercury cathode electrolysis cells

Abstract: 1486007 Automatic control of electrolysis PRODUITS CHIMIQUES UGINE KUHLMANN 29 Aug 1974 [17 Sept 1973] 37848/74 Heading G3R [Also in Division C7]. A mercury cathode cell for alkali or alkaline earth metal chloride electrolysis and having separately supported groups of anodes is protected against short circuits by measuring the current i for each group of anodes and the mean current i over all the groups and determining the value (i-i) for each group which is compared with a predetermined desired high threshold value #. If (i-i)-#>0, a signal is given which may be used either automatically to control via a computer raising of the appropriate anode support or to give warning to a manual operator that this is necessary. The electrolysis may further be controlled by also comparing (i-i) with a predetermined low threshold value # and if (i-i)-# < 0 and provided that the electrolysis voltage of the anode group in question exceeds a predetermined desired value, the anode support is lowered. In addition, when the mean electrolysis voltage or the voltage of a support becomes less than a predetermined safety value, the anode support(s) may be raised until the voltage is again above the safety value. All measurements may be taken continuously or at successive brief time intervals and be automatically electronically processed with a computer. Raising orders to the supports may take precedence over lowering orders while the lowering orders may be subject to specified time limitations with regard to preceding lowering or raising orders. The currents may be measured in terms of voltage drops at appropriate locations.

In the system shown, a multipolar edge magnetized ferrite disc 1 is secured to the drive shaft 7 of a motor 2, and rotates inside a coil 6 on an eccentrically mounted bobbin 5, thereby to induce an alternating flux in two protrusions (pole members) 9 of a flanged steel cover 8 which fits over and around the bobbin 5 and coil 6. The alternating flux thus linked with the coil induces a corresponding alternating voltage therein, and the magnitude of this voltage may be varied by adjusting the angular setting of the cover 8 relative to the disc 1, the adjustment varying the sizes of the air gaps between the disc 1 and the protrusions 9.
