Abstract: 108,674. Mascart, C. Aug. 7, 1916, [Convention date]. Flat endless-band elevators; auxiliary belts; driving-gear; feeding-devices; idler rollers and idler drums; tensioning; troughing rollers.-An elevator comprises two travelling bands 1, 10, Fig. 1, which grip the material raised between them. The tension of the band 1 is maintained constant under all atmospheric conditions by adjusting the weights 8, or varying the tension of a spring, and the tension of the band 10 can be regulated by adjustment of the drum 13 by means of sliding bearings moved by screws. The band 1 is driven by a motor 2<1>, and the band 10 is driven by the friction between it and the band 1 and the material to be transported. The band is supported by rollers 11, or fixed transverse guides, and its edges are curved inwardly either by rollers 12 or fixed angle members 16, Fig. 3. If it is desired to raise heavy materials, the band 10 may be pressed against the band 1 by curved rollers 15 carried by a frame which is forced downwards by springs 15<1>, 15<2> or by a weight. The passage of the materials below the drum 9 is facilitated by mounting the drum on a movable frame held in place by springs or weights, and, if necessary, the drum 2 is mounted in a similar manner. The pressing and supporting rollers are formed with holes 30, Fig. 8, so that any material which is carried between the band and roller can pass through, and fall through the ends 31. In a modification, the drum is composed of bars mounted in perforated disks. The elevator may be fed by a dredger device driven by the drum. The Specification as open to inspection under Sect. 91 (3) (a) states that the band 10 may be driven by the motor 2<1>, or by a separate motor enclosed in or driving the drum 13. This subject-matter does not appear in the Specification as accepted.

[Classes 83 (ii) and 83 (iv)] Angular bending; curving.-In making bearings and like cylindrical objects from steel-backed white-metal, bronze, &c. strip, the strip edges are deflected and set by rolls towards the axis of bending to counter anticlastic curvature produced in the bending rolls, arranged normal to the strip length and parallel to the bending axis, so that after the leading, irregularly-curved part of the strip is discarded part-cylindrical elements of constant curvature and plane section successively may be cut from the strip. The strip 1, Fig. 5, is fed from a coil 2 through setting rolls 5A, 6A, 7A, which downwardly deflect the strip edges, and under a back-tension roll 8 to the bending rolls 9, 10, the line joining their axes being inclined to the normal to the strip 1 to produce a constant curvature, that is adjusted by screw-shifting the plate 15 carrying the rolls 9, 10 about an axis 17. To produce liners of equal length the rolls are automatically stopped when the strip end contacts a stop 12 electrically controlling hydraulically-operated and fixed abutments which grip the strip 1 for radial severing by a reciprocating cutter 11, the severed element falling free and re-starting the rolls. The setting rolls 6A, 6B, Fig. 9, comprise oppositely tapered flanges 61, 62 axially adjustable for differing strip widths and changeable for different deflections dependent on curvature, the pass being variable to suit the strip thickness. In a modification the bending rolls 8, 9, 10 may be three roll, offset abutment or draw through types, Figs. 1-3, not shown, and the bending and setting rolls may be combined. In a further modification a continuous feed and a flying shear are employed and a multi-edged cutter operating in both directions may be used. In another modification the strip may be sized and small irregularities and any residual anticlastic curvature be removed by nipping between the final bending rolls. If the strip is trimmed to close tolerance, punched, marked, &c. no further treatment is needed after bending.

Title: Temperature-responsive means for actuating a valve, switch or other device
Inventor: FORBES MURRAY KEMBALL
IPC: H01H35/26
Filed: 1955-04-15
Abstract: 803,648. Temperature - responsive actuating-elements. SERCK RADIATORS, Ltd. March 15, 1956 [April 15, 1955], No. 10874/55. Class 64(2) A temperature-responsive actuating-element has a rod 13 held in normally by abutment on a spring-loaded valve or switch but which moves axially out of a container 4 upon expansion of a fluid, e.g. oil, in a chamber, e.g. containing annular heat-conducting plates 6, to move the valve or switch against the spring-loading. In the event of leakage of the fluid, an abutment 19 is moved by the action of a spring 22 to actuate the rod against the spring- loading of the valve or switch, but under normal conditions the abutment is held inoperative against an adjustable stop 24 by the pressure of the fluid. The fluid space is bounded at one end by a flexible diaphragm 18, an annular partition piece 17 (to which the diaphragm is secured at its inner edge), a cylinder 16 (secured to the piece 17) and the abutment 19 (which is secured to one end of the cylinder 16). Any leakage of fluid, e.g. upon. rupture of diaphragm 18, permits the spring 22 to move the piece 17, with its attachments 16 and 19, to follow the outward movement of the rod 13. In Fig. 1, the fluid pressure acts on a piston 15 secured to the end of the rod 13, the fluid reaching the space between the piston and the abutment 19 by way 'of holes or notches in the piston. A rubber tube or metal bellows 23 is secured at its ends to the piston 15 and to a bush 14 in an end wall of the container 4 in order to enclose the rod 13 from the fluid. The axially adjustable, screw-threaded stop 24 for the abutment 19 is a sliding fit in an end cover 12 and is threadedly engaged by a member 27 bearing a cylinder 20 in which the abutment 19 is slidable. A sleeve 9 attached to the member 21 has a shoulder 10 on which a spring 11 bears to hold in place both the sleeve 9 and a pieec 8 which retains the plates 6, a cylindrical extension of the piece 8 abutting the shoulder 10. In Fig. 2 (not shown), the piece 8 is secured to the container 4 and from it extends a sealing bellows to a partition piece which is a disc having a boss forming the abutment 19 on which the cylinder 16 is secured. The adjustable stop 24 screws into a member loaded by a spring washer, the spring 22 which loads the abutment 19 bearing between the loaded member and a shoulder on a cylindrical extension of the disc. In Fig. 3, the rod 13 is shorter and enclosed by a bellows or rubber sock 39 the closed end of which rests in a cup-end 38 of a rod slidable in a guide sleeve 37 on which in turn the partition piece 17 is slidable. Any fluid leakage would cause the block 17, cylinder 16 and abutment 19 to be moved to the left by the spring 22 so that the cup-ended rod would hold the rod 13 in its extended position. The Provisional Specification describes also a spring and a piston-like abutment which it loads, both in a cylinder at one end of the container.

Title: Improvements in and connected with ventilating installations particularly intended for railway vehicles
IPC: B61D27/00
Filed: 1931-04-14
Abstract: 376,381. Ventilating vehicles. STONE & CO., Ltd., J., Deptford, and VIDAL, J. F. B., 18, Brandram Road, Lee, both in London. April 14, 1931, Nos. 11007/31 and 1756/32. [Class 137.] In a ventilating installation intended more particularly for railway vehicles, comprising a fresh air intake, an air treatment chamber and control means adapted to cut off the normal flow of air from the intake, through the treatment chamber to the enclosure, that part of the installation between the intake and the control means is adapted to be self-clearing of smoke or the like. In the form shown in Fig. 1, fresh air is drawn by a fan a through a louvre b, past a light-sensitive detector of smoke l, m and a filter f and passed through a heating chamber c to a duct g leading to the enclosure. In the event of smoke being drawn into the intake, as when a railway vehicle is passing through a tunnel, the light-sensitive device actuates a control damper j to cut off the duct g and pass the heated air directly back to the outer atmosphere by way of a duct h. In a modification, the chamber c and duct g are provided with a byepass so that - a mixture of heated and cool air may be supplied to the enclosure. In another modification, Fig. 4, the control means is disposed between the intake and the fan so that when the supply of fresh air is cut off, air is withdrawn from the enclosure by way of a duct n and recirculated. The air intake is rendered selfclearing by being divided to form two inlets b<1>, b<2> facing in different directions. When the damper is in the recirculation position, air from outside flows in at one inlet and out at the other. The chamber c may contain instead of a heating, a cooling, humidifying or drying means.
