Patent GB-843898-A (GB)
Title: Apparatus for controlling tension in a running wel
Inventor: AARON CHARLES
IPC: B65H23/06
Filed: 1958-11-10
Abstract: 843,898. Fluid-pressure brakes. CAMERON MACHINE CO. Nov. 10, 1958, No. 36082/58. Class 103 (1). [Also in Groups XVI and XXIX] Variations in web tension detected by a roller 12, over which the web 10 passes, cause an appropriate adjustment of brake arms 16, 18 acting against the action of a spring 92, on the shaft 14 of a roll being unwound. Should the tension increase, a diaphragm 38 within a cylinder 28 will move downwards, thereby forcing liquid into a chamber 94 of a pressureregulating valve 54. As a result, air pressure in a chamber 54 RP from a source CA is increased, thereby moving a diaphragm 78 to the right. The diaphragm 78 is connected by a piston-rod. 74 to a member 82 carrying a pivotally adjustable cam 84. As cam 84 moves to the right, a plunger 90 rises to decrease the air pressure in chamber 60 RP of valve 60, thus in a chamber 96 of a valve 56 and in brake cylinder 66 to reduce braking action. Should the tension decrease, the diaphragm rises, thereby causing a reverse of the previous operations to increase braking action. Initial web tension is varied by manual adjustment of a screw 98 of a valve 58. The valve 58 connects a diaphragm 80 within a cylinder 64 to the source of air pressure CA to vary the setting of cam 84 and thus plunger 90. In a modification (Fig. 2, not shown), the valve 58 may be situated at a considerable distance from the remaining apparatus. In this case, the valve 58 is connected to a pressure control valve 102 which supplies air to the diaphragm 80, the valve 102 being connected to the air supply.

Title: Improvements relating to apparatus for supplying a direct current load from an alternating current source
Inventor: CALVERLEY HENRY BOLTON
IPC: B60L9/08
Filed: 1954-12-14
Abstract: 819,345. Transformers. ENGLISH ELECTRIC CO. Ltd. Dec. 9, 1955 [Dec. 14, 1954], No. 36176/54. Class 38 (2). D.C. traction motors M 1 , M 2  are energized from single-phase supply 12 through rectifiers RT 1 -RT 4  and transformer 10 which has two output windings 14, 15 arranged for on-load tap-changing. For the lowerst output voltage contactors T o , T 1 , TT o , TT 1 , S 1 , S 2  are closed, so that the voltage supplied between rectifiers RT 1 , RT 3  and the negative motor terminal connected to the midpoint of reactor 16 is half the voltage between adjacent taps on winding 14 minus the voltage drop in reactors R 1 , R 2 , and the voltage supplied between rectifiers RT 2 , RT 4   and the negative terminal is half the voltage between adjacent taps on winding 15, less the drop in reactors R 3 , R 4 . The voltage steps are the same on windings 14, 15 and the two pairs of rectifiers effect full-wave rectification. By operation of a controller, contacts of the two groups T o -T 4 , TT o -TT 4  connected to taps on windings 14, 15 respectively are opened and closed in sequence so as to increase the voltage supplied to the motors. Contactor P is closed to nullify the effect of reactor 16 each time a single contactor of each group is closed. After contacts T 4 , TT 4  are closed to supply half the voltage of windings 14, 15, contacts J 1 , J 2  are closed and S 1 , S 2  opened so that rectifiers pairs RT 1 , RT 3 , RT 2 , RT 4  are connected to the other ends of opposite windings, viz. 15, 14 respectively. Continuation of controller operation now reverses the opening and closing sequence of the tap contactors and results in further increase in the motor voltage until, when To and TT o  are closed, the motor receives the full voltage of the output windings. Contacts B 1 , B 2  may be closed at appropriate times in the operating sequence to remove the voltage drop resulting from load current in reactors R 1 , R 3 . Reactors R 1 -R 4  may be individual to the rectifiers and replace current-sharing chokes BR. In a modification, Fig. 3 (not shown), reactor 16 is replaced by two reactors, one for each group of tap changing contactors, so that intermediate voltages are obtained when different.taps are selected from the two output windings. Specification 735,371 is referred to.

Title: Improvements in and relating to roof structures for halls
IPC: E04B7/12
Filed: 1937-12-31
Abstract: 508,551. Roofs; structural metal work. HUNNEBECK, E. M., and MANNESMANNROHREN-WERKE. Dec. 31, 1937, No. 36218. Convention date, Sept. 23. [Classes 20 (ii) and 20 (iv)] A roof structure comprises a sheet-metal skin in the form of a plurality of inverted trough-shaped beams arranged side by side and extending lengthwise across the span, the said beams being corrugated or otherwise profiled or ribbed, as shown at 2, Fig. 2, lengthwise of the span over the whole of the region or regions subject to compressive stresses, and being smooth, or corrugated to a less depth than in the compression regions, in the regions or regions subject to tension. The beams are arranged to be of greatest depth at the centre of the span as shown in Fig. 1, this effect being obtained in the case of the beam shown in Fig. 2 by bending the beam to a shallower curvature towards the ends of the span, but maintaining the beam of a uniform width throughout its length. The beam shown in Fig. 4 is corrugated in its horizontal upper portion 8, which is of uniform width throughout the span, and also in the inclined portions 7 for a distance extending below the neutral-axis ; the smooth portions 6 of the beam are strengthened by angleirons 21 welded to the underside of the beam. The inclination of the smooth portions 6 of the beam remains the same throughout the span, but the height of these portions increases towards the middle of the span, the inclination of the corrugated portions 7 being correspondingly varied to allow the depth of the beam to increase from the ends towards the middle of the span.. In a modification, the inclined sides, of a beam of trapezium cross-section are uniformly inclined from the top to bottom of the section, and the depth of the smooth portion of the beam gradually decreases towards the ends of the span ; this reduction in depth of the beam is obtained by narrowing the width of the beam at the base towards the ends of the span and increasing the width of the valleys or gutters provided between the beams. The beams are built up of sheets which are connected together by welding, riveting, &c. Those parts of the beams which are in tension may be formed of sheets having a higher tensile strength than those in the region of compression. The beams may be braced by elements which serve only for retaining the shape of the beams and may take the form of transverse members 3, Fig. 2, lattice work frames 4, Fig. 4, welded frames, or plates. The bracing elements may be more closely spaced near the middle of the span than near the ends. Channel-iron or other members may be used to connect the bracing elements of adjacent beams. A ceiling D of fire-resisting material may be supported from the bracing elements. The roof structure may be constructed by first assembling the beams, including the bracing elements, on the ground, and, either before or after the beams are connected together, lifting them into their position in the roof. Figs. 15 and 16 show two forms of corrugated sheets suitable for use in the regions of compression.
