Patent GB-316354-A (GB)
Title: Improvements in or relating to the production of glass in strip form and apparatus therefor
IPC: C03B25/08
Filed: 1928-05-01
Abstract: 316,354. Pilkington Bros., Ltd., and Lemare, E. B. May 1, 1928. Roller-way conveyers.-Relates to the method of making plate or sheet glass in which glass strips, produced intermittently, are received on a roller conveyer by which they are carried to and through a leer, and means are provided for reducing the speed of the rollers, after the glass has set, in order that the leer may be of reasonable' length. According to the invention, the roller bed consists of a number of groups of rollers A - - D, Fig. 1, driven through free wheel clutches, the speed of rotation of the rollers of each group being less than that of the rollers of the preceding group. A glass strip is received from the forming-machine by the group A. of rollers and is fed into the leer 1 at a speed of 30 feet a minute, say, and its speed is reduced when it reaches group D, to 3 feet a minute. In another form of the invention, the speed of the rollers is so varied as to retard the speed of the strip gradually. This may be effected by driving the rollers positively through variable speed devices. It may also be effected by driving alternate rollers by or through reversible variable speed devices, the rollers driving the strip forwards being separated by rollers driven in the reverse direction at a speed which can be varied, so that the effective speed of the roller bed as a whole can be varied.

Title: Method of and apparatus for making bead cables
IPC: B29D30/48
Filed: 1922-05-06
Abstract: 198.195. Pratt. A. C. Mav 6, 1922. Making wire articles; coiling.-A bead-cable for tyres is formed from a single piece of wire constituting one convolution for a core and six convolutions of helices overlying the core. The wire is drawn from a reel 51, Fig. 3, by wheels 48 and fed through a die 49 having a helical passage therein. These parts are carried by a shuttle 26, Figs. 1 and 3, rotating in a bearing 25 around the cable being formed, the die laying the helices of wire upon the cable and forcing it to circulate in a channelled support 76. An inner shuttle 32 rotating in the outer shuttle and at a greater speed drives the wheels 48 through a bevel-gear 42 thereon meshing with a bevel-gear 40 carried by the shuttle 26. The shuttles are driven by shafts 21, 22 clutched to gears 23, 24 freely mounted on the said shafts and meshing with gears 19, 20 on a main-shaft 12. A pawl 55 surrounding an eccentric on the shaft 12 drives a cam-wheel 65 having ratchetteeth and adjustable . cams thereon. After six, convolutions of helices have been laid on the cable one of the cams declutches the gear 23 from its shaft 21 thereby stopping the rotation of the die &c. about the cable. The shuttle 32 still rotates to feed wire through the die, but as such wire is constrained against circumferential movement by being attached to the last helix laid upon the cable it issues in straight form from the die. When one convolution of straight wire has been delivered, the second cam declutches the gear from its shaft 22 thereby stopping the feed of the wire. The convolution of straight wire is cut at a point half-way around its perimeter, the half convolution of wire projecting through the die constituting half the core for the next bead to be produced, and the hali convolution attached to the bead already formed, which bead has only half a core, is snapped between the helices so as to complete the core of this bead. The clutch 67, Fig. 5, on the shaft 21, when disengaged from the gear 23, presses against slidable rods 72 and compresses a fibrous disc 74 between discs 73, 75 thereby bringing the shaft 21 and the shuttle driven therefrom to rest immediately. The support 76 is provided with pivoted covers 78, 79 having depending webs to form one side of the channel, the entrance of which can thereby be varied in width. The bearing 25 and the shuttles 26, 32 are gapped so as to allow of the removal of the completed cable, the shuttle 26 having a circumferential slot 37 so that accurate registration of the gap therein with that of the shuttle 32 is not essential for the removal of the cable.

Abstract: 742,737. Clamps. LEE, D. H. March 22, 1954 [May 12, 1953], No. 13229/53. Class 44. [Also in Group X] - A gripping device for prestress bars used in the production of prestressed concrete (see Group X) comprises a collar through which a prestress bar passes axially, wedges within the collar surrounding the bar and two coaxial threaded surfaces on the collar of different diameters. The embodiment of Fig. 1 shows the device applied to a method of post-tensioning concrete. A bar 1 projects from a channel 3 in a concrete member 4 and is engaged by two, or more, oppositely spaced wedges 10 that are flat on all but their bar contacting surfaces which are shaped to have major surface contact with the bar 1. The wedges 10 are embraced in a tapering axial hole 12 in a collar 13, the threaded exterior surfaces of which engage an adjustable thrust collar 18, and a shaft 7 of a tensioning jack through adapting collars 16 and 17. A rectangular thrust-plate 19 with rubber facing 20 takes the thrust of the tension jack and when bar 1 is under tension the thrust collar 18 can be screwed down on to the thrust plate 19 to allow the removal of the tension jack while retaining the bar under tension. In a second embodiment the shaft 7 is connected to the collar 13 by an internal thread and the thrust collar 18 comprises a short cylinder threaded on to the collar 13 and butting against a plain cylinder which acts as a distance piece to the thrust plate. The wedges may have arcuate outer surfaces in cross-section and lie within a tapering aperture of correspondingly circular cross-section in the collar 13. The bar engaging surfaces of the wedges may be grooved to mate with ribs raised on the bar or may be serrated to grip the bar.

[Class 118 (i).] A combined fire and burglar alarm comprises a clockwork bell 2 the release lever 3 of which is held inoperative by a fusible or in flammable mass 4 in a pan 5. The latter is carried by a pivoted lever 6 to the lower end of which a burglar trip-cord 7 is attached. Fusion of the mass 4 or a pull on the cord 7 releases the lever 3. The latter, in falling, may bridge contacts 14 in an external alarm circuit. In a modification, the pan 5 is integral with the lever 6. In another modification, Figure 3, the pan 5 is carried by a pivoted arm 9 and normally is supported by a hook on a pivoted lever 10, 11. This lever can be rocked by a trip-cord 7 or push-rod 22 to release the pan 5 and lover 3. The lever 10, 11 may be moved to an inoperative position and the pan supported by a combustible cord engaged in a hole 23. The lever 3 will then be released either by flames reaching the cord or by excessive heat fusing the mass 4. The lever 3 is biassed by a spring 12 and sliding weight 13. When the apparatus is set, a visual indicator 15 is held raised by a cord 20 wound on a drum 18 on the clockwork shaft 19. Fall of the indicator shows that the clockwork needs re-winding.

Each nozzle is moved about its pivot by a coil 44 coacting with a permanent magnet 46 and fed by an amplifier which receives electrical input signals from circuitry 60 incorporating bridge circuits and variable resistors. Two of the resistors, one for each nozzle, are ganged and manually operated by a position control means 56 whereby both servopistons 16 are operated together. A normal bias control means 54, operating further ganged resistors controlling one only of the nozzles, causes a change in the relative positioning of the servopistons to tilt the roller. The servopistons operate potentiometers 58, 59 which provide feedback signals to balance the bridge circuits.
