Title: Improvements in looms for weaving
Inventor: AMENGUEL JEAN
IPC: D03J5/06
Filed: 1968-01-10
Abstract: 1,213,587. Dummy shuttle looms. J. AMENGUAL and G. LANG. 10 Jan., 19681[24 Jan., 1967], No. 1530/68. Heading D1E. Dummy shuttle, Fig. 9. A double-acting dummy shuttle has beaks 8, 9 and pegs 11, 12 disposed in a recess in the front of the shuttle body; the recess is continued to the ends of the body by grooves 3 to accommodate a thread guiding, eyelet which presents weft to a beak as the shuttle is being picked, the weft the running on the peg 11 or 12. Metal plates 13, 14 mounted in the bottom of the shuttle generate signals as they pass a coil on the slay; the plates may be flush with the bottom or may be within the thickness of the bottom so as not to show. Operation, Fig. 2. At the stage shown, an eyelet 5 places the weft 25 in the path of the shuttle 2 which takes a loop into the shed, the weft being still attached to the last-but-one pick (which was inserted from this end of the loom). When the shuttle passes the coil on the slay, it triggers a cutter 22 which cuts the weft inwards of the edge of the warp (not shown), thereby producing a tucked-in selvedge; at the same time the weft coming from the supply is clamped, so that continued movement of the shuttle straightens the weft out into a single pick. During beat-up, the eyelets moves forward with the slay (as shown at 4) to take up slacken between the clamp and the selvedge and so tauten the pick. Weft cutter, Fig. 13. Each cutter 21, 22 consists of a plate 33 having a notch 48 to receive the weft 28 which is cut by downward movement of a blade 49 operated by an electromagnet, the armature of which consists of a horizontally-disposed leaf spring terminating in a pin 51 engaged in a hole in the blade 49. The cutter assembly pivots on the temple housing 38 and is swung upwards out of the shed when struck by the slay during beat up. Weft clamp, Fig. 16. Eaoh weft clamp consists of a curved brake shoe 56, across which the weft 25 runs and against which it can be pressed by a metal band 57 attached to a stirrup 60. The clamp is released by a striker 64 on the slay during beat up, whereupon the stirrup 60 snaps past the armature 66 of an electromagnet 68. Energisation of the magnet as the shuttle passes the coil on the slay releases the stirrup, which is operated to clamp the weft by a spring (not shown).

Patent GB-364356-A (GB)
Title: Improvements in or relating to means for igniting mercury arc lamps and similar discharge devices
IPC: H05B41/10
Filed: 1931-01-19
Abstract: 364,356. Discharge lamps. SCHERING-KAHLBAUM AKT.-GES., 170, Mullerstrasse, Berlin. Jan. 19, 1931, No. 1737. Convention date, Jan. 18, 1930. [Class 39 (i).] A device for igniting mercury arc and other electricaldischarge lamps is provided with a locking circuit in parallel with the igniting current circuit, so that in the event of the lamp becoming extinguished i t cannot be reignited until the locking circuit is broken. In o n e form a mercury arc lamp 1, Fig. 1 is connected by leads 3, 4 to a supply 2, through a manual switch 6 and inductance 5 in series with the lamp. A tilting mercury-switch 8 is so connected that, on closing switch 6 current flows through a resistance 11, through contacts 9 of the mercury-switch to the lead 4 and through the inductance 5, thereby magnetizing a core 16 which attracts an armature 7 and tilts the switch 8. The resultant discharge, which is increased by a condenser 17 across the switch contacts 9, produces a discharge through the lamp. Due to its kinetic energy the armature 7 moves downwardly until contacts 10 of the mercury-switch are closed, thus closing an auxiliary circuit through a resistance 12 and coil 13 to the return lead, the excitation of the coil 13 causing the armature 7 to be held down and preventing the igniting circuit from being closed again while the switch 6 is closed. Since the coil 13 carries current during the running of the lamp, it consists preferably of several turns of fine wire ; alternatively the coil 13 may be omitted and a part or the whole of the coil 5 utilized. In a modification a time lag is introduced into the locking circuit, this arrangement comprising a tilting mercuryswitch 80, Fig. 2, with a dashpot 190 or the like connected to its armature 180. When the switch 6 is closed current flows through the lead 70, across contacts 90 of the mercury-switch 80, through a resistance 100, and across contacts 110 of the mercury-switch 120 to a solenoid coil 5, thus magnetizing the core 130 of the latter and causing the mercury-switch 120 to tilt and open its contacts 110, thereby interrupting the current through the inductance 5 and producing a discharge through the lamp 1. The closing of the switch 6 also causes current to flow through a shunted circuit comprising a solenoid coil 150 and resistance 160, the resultant magnetization of the core 170 causing the armature 180 to tilt and opening the contacts 90 of the mercury-switch 80, so that the further action of the igniting device is prevented. The dashpot 190 serves to delay the cutting out of the igniting circuit. In another modification a thermal switch is used as a time element.
