Title: Tool following arrangement
IPC: B23K9/127
Filed: 1975-04-18
Abstract: 1493078 Automatic position control MESSER GRIESHEIM GmbH 18 April 1975 [20 April 1974] 16096/75 Heading G3R A device for ensuring that a tool follows a path on a workpiece includes a magnetic field generator and a pair of sensing heads one on each side of the path, which may be a welding gap. Signals from the heads are fed to a horizontal tool adjusting device which also receives signals from a pair of capacitive height sensors. As shown in Fig. 1, a welding torch 11 is connected to a scanning device 12 which causes the torch to follow the gap 20 between workpieces 18, 19. The device 12 includes a yoke 25 and A.C. coils 26, 27 producing a transverse magnetic field 23, and sensing heads 29, 30 with surfaces 31, 32 arranged to respond to small changes in magnetic field. The heads may be semi-conductor devices. Output coils 44, 45 are electrically connected in opposition and produce, through amplifiers, a signal which adjusts a lateral positioning device 13 for the welding torch 11. Each sensing head is provided with a capacitive height-measuring device 39, 40, the outputs from which are compared together to produce a compensating signal which is combined with the lateral adjustment signal for the torch. The mean height of the scanning device 12 may also be regulated using the signals from devices 39, 40. Differences in height between the workpieces may also be compensated by auxiliary windings on the sensing heads 29, 30, Fig. 3 (not shown). The two heads may be staggered in the direction of travel to allow positioning closer to the gap 20.

The helical screw threads have a greater pitch distance at the thread tip than at the root so that they interlock by axial "squeezing" of the threads. The dovetail may be semi or full and a single screw thread may be used in place of the two-stage thread shown. A seal may be provided by a polytetrafluoroethylene ring 57 or by metal-to-metal contact between tapers, as at 55. Further, the screw threads may taper axially, if desired.

Title: Improvements in or relating to apparatus for the manufacture of bottle caps from strip material
IPC: B21D51/44
Filed: 1952-06-26
Abstract: 736,504. Feeding webs. EVANS, D., and EVANS (DAIRY ENGINEERS), Ltd., D. Sept. 28, 1953 [June 26, 1952], No. 16150/52. Class 100 (1). In apparatus for the manufacture of bottle caps from metal foil strip, the strip 14 is fed downwardly along a vertical guide slot 18 by a continuously rotated feed roller 12 having a roughened feed segment 20 adapted to engage the strip and a dwell segment 21 of smaller diameter not engaging the strip so that the strip is advanced intermittently. The roller 12 is driven by a gear 19 and engages the strip through a slot 16 in one of the spaced parallel walls 11 forming the guide slot 18. A serrated backing roller 22 mounted on a spring-loaded arm 26 is arranged to maintain the strip pressed into engagement with the surface 20. A stop 29, limiting movement of arm 26, prevents the backing roller displacing the strip into engagement with the segment 21. The strip is led from a reel 32 mounted on a support 35 under a floating pulley 33 compensating for sudden jerks and over a pulley 31 guiding it into the slot 18.

Title: Film-forming composition
IPC: C09D129/10
Filed: 1954-06-01
Abstract: A composition comprises a solution in a two-type solvent of an organic titanium ester and an organic solvent soluble vinyl resin having from 0.01 to 0.25 free hydroxyl groups per vinyl group. The two-type solvents comprise volatile monohydric alcohols such as benzyl, butyl and isopropyl alcohols, which are used in conjunction with resin solvents such as methyl ethyl ketone, ethyl lactate, xylene, chlorinated hydrocarbons and ethylene glycol monoethyl ether. Vinyl resins exemplified are a terpolymer of vinyl chloride, vinyl acetate and vinyl alcohol, a copolymer of vinyl acetate and vinyl alcohol and polyvinyl alcohol in which 5 per cent of the hydroxyl groups have been acetylated and 80 per cent combined as vinyl butyral.  Titanium esters specified are alkyl titanates, e.g. tetrabutyl-, and tetraisopropyl-; carbocyclic and heterocyclic titanates, e.g. tetrabenzyl- and tetrahydrofurfuryl-; aminoalkyl titanates, e.g. triethanolamine-; alkoxytitanium acylates, e.g. acrylates and methacrylates (which may be in the polymerized form); and condensed esters produced by partial hydrolysis of the above.  Up to 2 per cent based on the resin of a carboxylic compound, e.g. maleic acid, may be included in the compositions, which may also contain pigments such as titanium dioxide, zinc oxide, lithopone and white lead.  The compositions may be cast, e.g. on glass or steel, to give quick drying films having high resistance to water, alkalies and organic solvents (including the original solvent) and which are of use in insulating applications.

Title: Improvements appertaining to driving mechanism for the flyerspindles of spinning, doubling, twisting and like machines
IPC: D01H1/241
Filed: 1932-06-14
Abstract: 403,107. Stopping-arrangements for spinning, twisting, and like machines. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd., and ANDERSON, J. K., Welling- ton Foundry, Leeds. June 14, 1932, Nos. 16773 and 16697. [Class 120 (ii).] In spinning, doubling, twisting, and like machines, especially those for jute, flax, or hemp, rebound of the tin roller and the consequent reverse movement of the flyers when stopping the machine are prevented by pawl and ratchet mechanism connected with the tin roller shaft and operable upon movement of the stop-rod of the machine. As shown in Fig. 1, a ratchet wheel 2 is mounted on the tin roller shaft 2<a> and a pawl 3, under the control of a plunger 8<a> in an air cylinder 9, is carried by a lever 4 adapted to be engaged by a cam surface 5 on the starting-rod 6. The position of the parts during the running of the machine is shown in dotted lines, the pawl 3 being disengaged from the ratchet wheel 2 and a spring 12 in the cylinder 9 compressed by the plunger 8<a>. Upon movement of the rod 6 to the position shown in full lines to stop the machine, the lever 4 is operated to follow it by the spring 12 the action of which is controlled by the expulsion of air from the cylinder 9 by the plunger 8<a> through a regulatable cock 10. As shown in Fig. 2, the ratchet wheel 2 is fixed to the framework of the machine and the pawls 20 are carried by a disc and engaged by pins 19 on another disc fixed to the tin roller shaft 2<a> and mounted inside the former disc, the arrangement being such that, when the stop lever 6 is operated to slacken the driving belt 7<a> to stop the machine, a brake 16 is applied to the pawl-carrying disc and any rebound of the shaft 2<a> with consequential relative movement of the discs causes the pawls to engage the ratchet wheel.
