Filed: 1918-12-14
Abstract: 136,614. Grant, J. C. Dec. 14,1918. Materials, special, for cords, &c. - Twine or cord is formed by twisting strips of paper obtained by joining, by an adhesive, sheets of paper of substantially rectangular form to form a strip of indefinite length, which may be divided into narrower strips and twisted, and, if necessary, the individual threads so formed are twisted together. The sheets may be joined by gumming a thin strip on either or both sides of the joint, or on the upper side of one sheet and on the lower side of the other; or by mean of a lap joint the edges of which are preferably of zig-zag or wavy contour. The agglutinant is of thin consistency and renders the contact surfaces pulpy so that the joint is consolidated under pressure. The strip may be waterproofed or treated in any well known manner before or after twisting. A suitable apparatus for jointing the sheets is shown in Fig. 1. Sheets are fed from two points so that those from one point are interposed in the space left between those from the other point. A roller 9 in continuous contact with a band 10 passing through a bath of adhesive 11, is oscillated so as to contact with the sheets, which pass between pressure rollers 5, 7 around heated rollers 12 and 15, and are wound on a spindle 16.

Title: Improvements in or relating to temperature control mechanism
Inventor: CAPARONE MICHAEL JOHN
IPC: G05D23/275
Filed: 1953-07-31
Abstract: 776,821. Valves. ROBERTSHAW-FULTON CONTROLS CO. July 31, 1953, No. 21373/53. Class 135. A temperature control device, e.g. for a gas water-heater, comprises control means movable between on and off positions to control the supply of operative energy to the heater, e.g. the valve 40, thermal means 68 for moving the valve through a lever 72 adjusting means 76 for altering the fulcrum of the lever and setting the temperature at which the valve is normally actuated, setting means, e.g. the screw 74 screwed inwardly beyond its normal movement to position the lever away from the fulcrum, e.g. to engage a pivoted hook 92, and permit a temperature rise above that normally set by the adjusting means, and resetting means 84 for automatically returning the lever to the fulcrum when a predetermined temperature higher than that set by the adjusting means has been attained. On turning and depressing the knob 22 of the cock 18 a plunger 32 rotates the lever 62 against a spring-loaded armature stem 58 of an electromagnet 56 controlled by a thermo-couple heated by a pilot burner. When the magnet 56 is energized a spring 64 loading the valve 40 is relieved and the valve may be opened by the thermal element 68 acting through a lever 72, a snap-acting device 50 and an over-ride device 46. For normal operation the pivot of the lever 72 is on the end of a temperature-adjusting screw 74. Should a tank full of water at a higher than normal temperature be required the lever 72 is moved by the screw 74 to engage a pivoted hooked bell-crank 92. When the high temperature has been reached a collar 88 on the element 68 moves upwardly and turns a lever 84 about a pivot 86 which through an adjusting screw 85 disengages the hooks 92 from the lever 72 to allow it to re-engage the screw 74 under the action of a leaf-spring 78 for normal temperature control. A separate spring-loaded push button and lever may be used in place of the screw 74 for moving the lever 72 into its high temperature position.

Title: Improvements in or relating to heating systems for paper dryers
IPC: D21G9/00
Filed: 1925-08-26
Abstract: 251,824. Broughton, A. E. Aug. 26, 1925. Drying. - In a steam heating system for the drying rolls of a paper-making machine, comprising a number of steam supplies separately serving corresponding groups of drying rolls, the pressure and temperature of the steam supplied to the various groups are independent of one another, the available heat of the steam supplied to each group being substantially wholly utilized in that group. The headers 2, 3 supplying steam to the rolls 1 at the dry end of the system are supplied either from the boiler through a pipe line 7 through a reducing valve 8 or from a low pressure line 9 e.g. from the machine engine exhaust, the line 9 supplying through a reducing valve 11 the headers 4, 5 at the wet end. Alternatively the header 5 may be intermittently supplied by a line 12 with boiler steam that has been used to force the condensed steam from traps 29 provided for draining the drying rolls 1. The condensed steam is led from the rolls 1 by a pipe 15 to a receiver 22 from which air is allowed to escape through a water trap 23 and thermostatic valve 24, the water leaving the receiver 22 by a pipe 30 to a steam trap 29 whence it is forced by boiler steam into a common high pressure receiver 52. The trap 29 is of the tilting direct return type operated at boiler pressure, steam being supplied thereto through a pipe 39 and valve 38 and exhausted therefrom through the pipe 39, valve 40 and check valve 42, and is mounted upon bearings 43 so as normally to be held horizontal by a weight 44, levers 49, 50 being provided for actuating the valves 38, 40 upon tilting movement of the trap.

Title: Control means for toric race transmissions
IPC: F16H15/38
Filed: 1937-08-06
Abstract: 482,493. Variable - speed friction gearing. GENERAL MOTORS CORPORATION. Aug 6, 1937, No. 21708. Convention date, Aug 6, 1936. [Class 80 (ii)] Relates to toric race frictional gearing with rollers 20 operating by precession in forked carriers 22 each moored at one end on a swivelling anchoring pivot 24, Fig. 2, and comprises a three-armed control lever 50, Fig. 1, in line with the roller axis. Each roller engages driving and driven races 10,12, and is integral with an arbor 26 which turns and slides in bushes 28, 28a pinned to the two limbs of the carrier 22. Precession to change-speed is initiated by sliding the carrier axially upon the arbor 26, which has the effect of tilting the roller about an axis joining its two friction, contact points. To this end, the arms 52, 56, 54 of the lever 50 are connected respectively to the carrier 22, to the arbor 26, and to a sliding central control sleeve 64. The arm 52 is pivoted to the enlarged or piston end 44 of a control pin 42 which passes through the arbor 26 and is connected at 40 with the outer carrier limb so as to push and pull the carrier while the roller and pin rotate. The piston end 44 damps vibration at 32. The second lever arm 56 engages at 58 over a control flange 34 rigid with the inner end of the arbor 26. Axial displacement of the sleeve 64 rocks the lever 50 and this effects an axial displacement of the carrier upon the arbor 26 and the roller 20 so starting the spiralling of the roller on the discs, which terminates when the arbor 26 has come again into line with the lever arm 54, " restoration " thus being automatic. The control sleeve 64 may be actuated by a manual lever 66, Fig. 3. The control lever 50 and pin 42 are prevented from rotating with the flange 34 by a stop 74, Fig. 1, on the carrier. If the direction of rotation of the driving-disc 10 is reversed, the lever 50 turns back with the reversed roller until the lever is stopped by another stop 74a, after which the control acts as before. In the arrangement so far described, there is a separate control lever 50 for each roller. There is described with reference to Figs 7 and 8 (not shown) an arrangement in which the control is applied to the outer end of a single master roller, the inner end of the central control pin of which moves a secondary control sleeve sliding on the central shaft and operating the remaining rollers as does the sleeve 64, Figs. 1 and 3. The invention may be applied to transmissions in which two sets of rollers and races operate in parallel.
