Title: Improvements in or relating to traversing-means for yarn winding machines
IPC: B65H54/14
Filed: 1960-06-25
Abstract: 944,105. Winding yarns. J. DAUTRICOURT. July 4, 1961 [June 25, 1960], No. 22344/60. Heading D1J. A conical member 23, Fig. 4, has a yarn guiding groove 28 that is continuous where it guides the yarn from the small end to the large end of the conical member, and which is interrupted or reduced in depth where crossing points 29 occur as the groove guides the yarn from the large end to the small end of the conical member. Fig. 5 is a section showing a crossing point 29 of the groove 28,the section being taken along the longitudinal axis of the interrupted portion of the groove and across the continuous portion of the groove, and, as shown, the interrupted portion becomes progressively shallower as it approaches the crossing point where it is entirely interrupted. Alternatively, Fig. 6, the depth of the so-called interrupted portion of the groove 28 is made shallow for a short distance at each side of the crossing point 29. The groove 28 may be flared in crosssection adjacent to the surface of the conical member 23 either throughout its length or adjacent to the larger end of the conical member. Fig. 1 shows the conical member 23 incorporated in a yarn winding machine such that as the yarn is traversed on to a conical member 30, and subsequently on to a spindle 15, the resulting and progressive build up of the yarn package 37 causes a carriage 20 to slide along guide means until a finger 36 on the carriage actuates a switch 40 on the machine to stop the drive to the spindle 15. The carriage 20 is biased against movement by spring means or by a weight acting on a cord 32. The carriage 20 carries a yarn supply package 25. An adjustable yarn guide 34, on the carriage 20, prevents the yarn from running off the smaller end of the grooved conical member 23.

Title: Automatic lathe
IPC: B23Q7/04
Filed: 1958-07-15
Abstract: 836,864. Lathe-details. TAREX S.A. July 15, 1958 [Sept. 21, 1957], No. 22696/58. Class 83 (3). In an automatic lathe having a tool turrethead 13 carrying a device for transferring workpieces 4 from a magazine 8 into jaws 3 on a work-spindle 2, the device is lockable against rotation when opposite the magazine, and releasable when opposite the work-spindle so that the device can be rotated by said workspindle. The magazine is mounted in a recess 7 of a support 6, and has two pins 10 supporting the lowermost piece 4. The turret 13 has its axis at right angles to the work-spindle, and the device is held by a tool-holder 14 of the turret. The device consists of a head 20 rotatable in a bearing 21, and having a rod 22 carrying a locking member 24. The member 24 has locking-faces 25 and contacting-faces 26 engageable with faces 18, 19 of a head 17 of a fixed rod 15, a spring 29 tending to maintain the member 24 in alignment with the face 18. In use, the device is moved by a slide S towards the magazine, and a gripper, held by the head 20, enters the magazine. A piece 4 is gripped by a resilient member 27 of the gripper, which enters a bore in the piece, and by extensions 28 of the gripper, which hold the piece externally. On returning thes lide, the piece is extracted from the magazine, the head 20 having been prevented from rotation by engagement of faces 25, 18, which, on rotation of the turret through 180 degrees, disengage so that the head 20 is free to rotate. The spindle 2 has a hole 33 therein which engages a finger 34 on the head 20, causing rotation thereof. The piece is held by jaws 3 and the slide S is moved towards the magazine to allow rotation of the turret and so bring the series of tools into operation. As an alternative, a screwdriver, held by the spindle 2, could engage the slot of member 27 to drive the head 20.

Title: Improvements in or relating to luminous electric discharge tubes
IPC: H05B41/04
Filed: 1930-07-29
Abstract: 359,588. Discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand Ges. fiir Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin.) July 29, 1930, No. 22856. Convention date, Sept. 4, 1929. [Class 39 (i).] The initial discharge in a lamp is started by means of a transformer which though capable of producing the initial high potential required is considerably underdimensioned with regard to the full current taken by the lamp which may be five or more times the current which the transformer can supply. The latter is automatically disconnected from the circuit when the initial discharge is started, the discharge being maintained by a second transformer giving the full current at a lower potential. The Figure shows a circuit for starting and maintaining a discharge through a tube 3. The discharge is started by means of a small transformer 10 which is placed in circuit by closing the switch 13 and opening the switch 6. When the discharge has started, switch 6 is closed and switch 13 automatically opened thereby connecting the tube to the main supply 8, 9. The automatic operation of the switches may be effected by a spring, clockwork, or electromagnet. In a modification an autotransformer is used to start the discharge and the switches 6, 13 are replaced by a two-way switch which may consist of a rocking tube containing mercury which is operated automatically.

Title: An improved method of and apparatus for the manufacture of wired glass
IPC: C03B13/12
Filed: 1930-07-30
Abstract: 360,361. Glass manufacture. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST-GOBAIN, CHAUNY, ET CIREY, 1 bis, Place de Saussaies, Paris.-(Assignees of Pond, L. N.; 1013, Wateree Street, and Lewis, J. H. ; 1125, Wateree Street, Kingsport, Tennessee, U.S.A.) July 30, 1930, No. 22892. Convention date, July 31, 1929. [Class 56.] Rolling. - A method of making wire glass consists in introducing netting into a stream of molten glass which is flowing to the pass between a pair of forming rolls, and the method is characterized by the fact that the netting is introduced in such a manner that it changes its direction, after entering the glass, in order to pass between the rollers. The length of the bend formed in the netting is determined by adjustment of the speed of entry of the netting into the glass. The molten glass issues from a slot B in the end wall A of a tank furnace, and flows over a slab G into the pass D between a pair of forming-rollers E, F to be formed into a continuous sheet or ribbon. A roll H for feeding the wire netting I is arranged between the upper roll E and the furnace, and is pressed resiliently against the roller E. A shield L and a water-cooled plate M prevent the wire from becoming too hot and oxidizing before it is im. mersed in the glass. The wire netting passes between the rollers H, E, and the speed of the roller II is so controlled that it tends to drive the netting at a slightly greater rate than the speed of sheet formation, so that the wire forms a bend i instead of hugging the roll E. This bend tends to fix the level at which the wire is delivered into the forming-pass D and, therefore, its position in the glass sheet.
