Title: Improvements in or relating to electrical drives for sewing machines
IPC: H02K7/112
Filed: 1953-04-15
Abstract: 736,548. Gearing for stopping machinery. SCHWAB, M. April 15, 1953 [April 17, 1952 April 22, 1952], No. 10294/53. Class 80 (2). [Also in Groups VII and XXXIV] In a drive for a sewing-machine a movable element of a friction clutch is adapted to be coupled in one end position directly to the driving motor, and in the other end position to a brake disc driven at slow speed via a magnetic clutch, whereby the machine may be stopped in any desired position, when said element and disc are coupled together, by interruption of the electric supply to the magnetic clutch, The shaft 2 of an electric motor carries at one end the driving element 4 of a friction clutch and at the other end the driving element 37 of a magnetic clutch. A shaft 9, which is slidably mounted, carries at one end a clutch element 8 provided with a friction lining 7 and at the other end a grooved pulley 18 in driving connection with the sewing-machine. A disc 17, provided with a friction lining 23, is also carried by shaft 9. Depression of a lever 55 by means of a treadle serves to shift shaft 9 against the bias of a spring 61 for engaging lining 7 with element 4 to drive the sewing-machine, and also for simultaneously disengaging lining 23 from a brake disc 22 rotatably mounted in a fixed frame 16. A shaft 43 is then driven from the main drive of the sewing-machine via a chain (not shown) and a sprocket 44, when slip-rings on shaft 43 serve to convey electrical current to the element 37, whereby an element 36 of the magnetic clutch is coupled, via sprockets 33, 35 and chain 34, shaft 29, sprocket 28, chain 27 and sprocket-ring 26, to disc 22 for driving the latter at slow speed. On release of lever 55, spring 61 'returns shaft 9 to disengage elements 4 and 8, and to engage discs 17 and 22, whereby pulley 18 is driven at slow speed. A throw-over switch is then selectively operated to include either one of a pair of said slip-rings in the electrical circuit of the magnetic clutch, the periphery of each of said pair being formed with a gap so positioned that the magnetic clutch circuit is interrupted, to stop the machine, when the needle bar is located at either top or bottom position. In a modification friction linings 8 and 23 are both carried by the same element of the friction clutch, and the brake disc is driven by a pinion engaging an internal gear ring provided on said disc. In a further modification the magnetic clutch, and the drive from the latter to the brake disc, are enclosed within the casing of the electric motor.

Title: Improvements in and relating to building of hollow walled structures
IPC: E04B1/16
Filed: 1934-04-11
Abstract: 426,098. Hollow walls; slabs; casting in situ. NOFRANGO, Ltd., and WALLER, J. H. DE W., 1, South Frederick Street, Dublin. April 11, 1934, No. 10908. [Classes 20 (ii), 20 (iv), and 87 (i)] The outer and inner sections of a hollow wall are constructed separately in a horizontal position by securing a reinforcement to a rigid frame corresponding to the height of the wall from floor to ceiling, covering the reinforcement with concrete, screeding the concrete to the required thickness, and then, when the concrete has set, raising the two sections to the vertical position and placing them together with the two frames disposed within the cavity formed between the sections. Each rigid frame comprises vertical studs 6, and top and bottom rails 7, 8, as shown in Figs. 1. and 2, and the reinforcement may consist of a sheet 3 of hessian stretched tightly over the frame and secured thereto. A beading 9 is secured to the end studs 6 and bottom rail 8, and a batten 10 is secured to the top rail 7. The hessian may be first given a wet coating of concrete slurry whereby it is caused to shrink. Concrete is then poured over the impregnated hessian and levelled to the depth of the beading 9 and batten 10. The sections are then raised and placed back to back with the studs 6 in contact, as shown in Fig. 4, and such studs are secured together by spikes &c. The sections may also be secured together by the door and window frames fastened thereto. The inner section may be coated with plaster instead of with concrete, and if desired the inner surface of each skin may be given a coating of concrete. At a corner, a concrete post 12 may be cast between adjacent sections as shown in Fig. 6 by means of removable shuttering 14 secured to a temporary wooden upright 13 by wires, bolts, &c. 15. At intervals in a straight wall, a T-shaped concrete post 19 is cast as shown in Fig. 7, such post being cast in the space provided between the ends of adjacent sections, the deep stud 16 of the partition wall framing, and shuttering 18 carried from the latter by bolts or wires 17. If desired, the end studs 6 may be set back as shown in dotted lines in Figs. 6 and 7 so that the concrete 11 projects into the concrete posts. The concrete of the posts is made fairly dry or the ends of the wall elements which make contact with the posts are covered with a suitable substance to prevent union of the post with the wall. The framing between the two sections may be removed at the top and a girder of reinforced concrete may be cast in position so as to extend completely around the building. The girder may, alternatively be of wood. The studs 6 of opposite sections may be of equal or unequal thickness, and they may be of a thickness equal to, or less than, the thickness of the air space and arranged in staggered relation. The framing may also be of metal and covered with expanded metal &c., or other vegetable fabric instead of hessian. Specification 376,259 is referred to.

Title: Improvements in or relating to methods of producing gravure printing plates from half-tone printing plates
IPC: G03F5/20
Filed: 1937-04-17
Abstract: 494,157. Photo-mechanical printing- surfaces. DULTGEN, A. April 17, 1937, No. 11029. Drawings to Specification. [Class 98 (ii)] Photogravure printing surfaces are produced by etching through a resist prepared from registering half-tone and continuoustone images, a carbon tissue forming part of the said resist being used to receive at least the continuous-tone image. The latter may be formed by making an ink print from a half-tone original plate and making therefrom a photographic print having the image sufficiently blurred to obliterate the halftone formation. In one method the two images are printed in superimposition on positive material which is then used to print on a carbon tissue. In a modification, an ink print on a transparent surface is printed onto carbon tissue and also onto a soft-working negative material, a positive from which is then printed in register on the carbon tissue. The original plate may also have the hollows filled with ink and an intaglio print taken therefrom, the resulting negative being printed onto positive material which is used to print as above. The half-tone negative may also be printed on a resist layer which is developed and a carbon tissue printed from the continuous tone negative superimposed thereon or the two negatives may be printed on separate carbon tissues, which are developed and superimposed. A single strength of acid may be used for the etching.
