Title: Improvements in and relating to wire cloth for paper-making machines
IPC: D21F1/10
Filed: 1926-06-09
Abstract: 262,336. Hõhnle, C. Kurtz-, and Kurtz, H. June 9, 1926. Wire cloths.- To eliminate excessive wear of the wire cloth and the edges of the suction boxes, the seam or seams of the wire cloth are arranged inclined to the direction of travel so that the seams move gradually over the edge of the suction box, and the sudden jerk which is usual with the ordinary transverse seams is avoided. The inclined seam may be obtained by staggering the ends a, b of the wire to be joined as shown and removing the projecting side pieces. In long wires, several seams are arranged in order to obtain the desired inclination with a minimum of waste. The wire cloth may be woven into suitable form by adding warp wires on one side and taking away an equal number on the other side.

Title: Improvements relating to push-button control mechanisms
IPC: B23Q5/18
Filed: 1939-05-19
Abstract: 528,996. Keyboard switches; actuation of switches. WEBSTER & BENNET, Ltd., and MAYO, H. T. May 19, 1939, No. 14934. [Class 38 (v)] [Also in Group XXIX] A push-button control mechanism comprises a number of switches actuated by a series of slidable push bars arranged parallel with each other and adapted to act through a series of slidable or rotatable members. Push-button bars h fitted with push-buttons i are arranged in a, single row in a frame a and urged towards their inoperative position by springs j. Each bar has one or more pins p adapted to co-operate with inclined grooves o in transverse bars b adapted to actuate switches against the action of springs e. Each push-button when depressed acts through an inclined surface or surfaces and at the same time an additional pin on the bar passes through a similar gap in a locking bar, which snaps back under the influence of spring q to lock the particular push-button until a second pushbutton or unlocking push i<1> is depressed. The push bars may pass through inclined holes in the bars and the pushes may be arranged in two banks, grooves being provided on both sides of the locking bar. In a modification, the actuating and locking members are in the form of discs freely mounted on a common spindle and are actuated by push bars arranged around that spindle. The discs have inclined slots to co-operate with pins on the push bars, V-shaped cam-grooves to co-operate with the switch spindles, and spring-loaded plungers to return them to their inoperative positions.

Title: Improvements in or relating to spring assembly
IPC: F16F3/04
Filed: 1949-06-03
Abstract: 672,711. Spring mechanisms. GENERAL BRONZE CORPORATION. June 3, 1949 [June 3, 1948], No. 14944/49. Class 108(iii) [Also in Group X] A spring assembly comprises a pair of spaced bracket members, a rod rotatably mounted in one of the bracket members and having a fin extending h e 1 i - cally around the peripheral face thereof in one direction to a point between the ends of the rod and extendi n g helically around the peripheral face thereof in the other direction from the point towards the other end of the rod, a guide member attached to the other of the brackets and telescopically receiving the rod, the guide member having a guideway complemental to the fin on the rod, and a coiled tension and torsion spring attached to the rod at one of its ends and to the guide at its other end, whereby when the rod and guide are telescopically moved in relation to each other, the tensional and torsional forces of the spring will be varied. In the arrangement shown, as applied to a balancer for a vertically slidable window sash, a spring 10 is secured at its upper end 12 to one end of a rod 14 which is rotatably mounted at that end, in a bracket 18 attached to a window frame. The lower end of the spring is secured to a tubular guide 24 and a bracket 28 which is attached to a window sash. The spring is prestressed both tensionally and torsionally. The other end of the rod 14 is located within the guide 24 by an abutment 14<SP>1</SP>. A guideway 26 at the upper end of the tube 24 co-operates with fins 34 and 36 on the rod 14, which are formed by twisting the rod in opposite directions from an intermediate point 7-7 towards each end. In operation, extension of the assembly from the position shown in Fig. 8, increases the tension on the spring 10 and decreases the torsional effect thereon, due to the rotation of the rod 14 relative to the guide tube 24, until the guideway 26 is coincident with the intermediate section 7-7 of the rod. Further extension of the assembly rotates the rod in the opposite direction and the increased tension of the spring is then substantially counteracted by an increasing torsional effect thereon. In a modification, Figs. 11 and 12 (not shown), the torsional pre-stressing of the spring 10 is adjustable by means of a pin to which the guide tube 24 is secured and which is rotatably mounted in the bracket 28, the pin being held against rotation by the spring, by means of a pawl mounted on the bracket which engages notches on a head on the pin. The spring assembly may be enclosed in a casing 32, which is secured to the bracket 18. The Specification includes formulae for determining the lengths of the fins from each end of the rod to the point 7-7.

Title: Improvements in gas mantles
IPC: F21H1/00
Filed: 1933-05-24
Abstract: 402,348. Gas mantles. SOUTHMETROPOLITAN GAS CO. and PRESTAGE, A. J., 709, Old Kent Road, London. May 24, 1933, No. 15028. [Class 75 (i).] The inner and outer skeletons d, e of a double mantle are separated from one another except at their ends. The foundation of the mantle is made in the usual manner by drawing one half of a length of impregnated tubular fabric, tied with thread at the middle, inside out over the other half and attaching the open ends to the mantle ring. The separation of the skeletons is effected by supplying air to the interior of the mantle during incineration, thereby producing a greater shrinkage of the inner layer. The mantle may be incinerated by a gas burner supplied with air under a slight pressure, the gas supply being cut off when the fabric is alight, or the mantle may be suspended by its ring in a hole in the roof of a casing connected with a source of low pressure so that a current of air is drawn from outside into the interior of the mantle.
