Abstract: 446,800. Gas holders. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES., Nuremberg, Germany. Sept. 16, 1935, No. 25719. Convention date, Oct. 18, 1934. [Class 54] The cover or disc of a gas holder of the telescopic, waterless disc, bell, or corrugated elastic wall type is made flat on its lower surface and a cup containing liquid is provided into which the lower surface of the cover or disc dips when in its lowest position, thus enabling the holder to be freed completely of gas. The liquid is preferably a corrosionpreventing liquid such as oil, oil and water emulsion, or water with additions such as sodium bichromate. Fig. 2 shows a waterless disc holder provided at the bottom with a layer of liquid 9. The inlet and outlet gas pipes open into a dome 13 formed on the disc 11. Fig. 4 shows a holder having a flat cover 21 and a corrugated elastic wall 22 which when the holder is empty lie in a cavity 23. The part of the cavity inside the holder is filled with a corrosion preventing liquid and the part outside the holder contains water preferably mixed with a paint-preservative. Superfluous liquid is removed and the liquid pressures maintained equal by overflow pipes 26, 27.

Filed: 1936-09-24
Abstract: 486,106. Control of motors; changespeed and reversing gearing. MATHERS, J. H. Sept. 24, 1936, No. 25974. [Class 38 (iii)] [Also in Group XXIV] Travelling to predetermined limits.-In a distant control system for power installations on vehicles or for marine purposes, in which change-speed or reversing gear is operated by an electric motor 8 controlled for forward or reverse operation by electromagnetic switching means 25, 26, under the control of a master switch 12, and in which the motor actuates limit switches, the motor operates a screwthreaded shaft 6 carrying a nut 15 coupled to an arm or lever mounted on the operating shaft 10 of the change-speed or reversing gear, so that on operation of the motor the nut moves longitudinally on its shaft and rocks the operating shaft 10. The lever 2 carrying the nut 5 is pivoted at 3 to a lever 4 on the operating shaft 10 and is locked to that lever by means of a pin 9 which can be removed to permit hand operation of the gear. The controller 12 comprises a handle 13 carrying contacts 13a, 13b, and by operating the handle in one direction or the other the corresponding reversing contactor 25 or 26 is closed. The motor 8 operates a switch finger 15, and at the limit of travel a switch 18 or 19 is opened to de-energize the closed contactor. When the handle 13 is returned to its neutral position, the other reversing contactor is closed and the motor operates until the finger 15 is returned to the neutral position. The motor 8 operates through gearing 7 which may he connected to one arm of a reaction lever 32 pivoted at 33, the other arm coacting with a spring 35 which acts in one direction of movement to relieve the thrust.

Filed: 1926-10-20
Abstract: 284,012. Lester, W. G. Oct. 20, 1926. Stencil-printing apparatus.-In a machine for stencil-printing on sacks and the like, the sacks are placed on radial arms 5 fixed to a sleeve 38 mounted on a fixed pin 6 carried by a stand 1, the sleeve 38 being intermittently rotated by Geneva stop mechanism to move the sacks into printing position beneath stencil screens 46 through which ink is applied by means of reciprocating squeegee bars 15. The racks are held in position on the arms 5 by movable side parts spring-pressed outwardly to grip the sack. The stencils are fixed by screws 39 to a frame consisting of guide rods 9, a plate 11, and crossbars 10. 10<a>. Each squeegee consists of a rubber strip fixed to a bar 15. the ends of which engage in slots in blocks 14 slidably mounted on the rods 9. The bars 15 are reciprocated by a rotary crank 21 acting through rods 20 connected by universal joints 22 to the bars 15, and each rod 20 carries at its end screws engaging lugs on a bar 15 to tilt the squeegee forward at the end of each stroke so that it is always inclined at a trailing angle to the screen, the bars 15 being raised off the screen to allow this tilting movement by means of trip devices 13. While the arms 5 are turning from one position to the next, the screens and the squeegee mechanism are raised as a whole by means of a rotary cam disc 27 engaging cam wheels on the underside of the plate 11 of the stencil frame. The Provisional Specification describes a machine controlled by two pedals, one for releasing the work-tablet to allow rotation thereof by hand, and the other for raising and lowering the screens. Ink is applied through the screens by means of taps from a receptacle arranged above the screens. Stencils.-The stencil screens consist of wire gauze parts of which are blocked out with nitrocellulose paint.

Abstract: 1,218,120. Dies. TOOLMASTERS Ltd. 4 June, 1968, No. 26618/68. Addition to 1,044,614. Headings B3A and B3W. The die sections of the parent Specification which have inclined outer walls corresponding to a tapered aperture in a support member are modified to facilitate grinding the sections accurately after wear by making the outer walls such as 38a, 39a parallel with the mating faces 52 of the die sections. In a machine for performing two successive punching operations on sheet metal stock, sectional dies 38, 39 are located in apertures (11), (12) respectively in lower bolster (10) by means of blocks 43-49 outer faces 42 of which are inclined to correspond to opposed faces (13), (14) respectively of the apertures (11), (12). The formed faces 40 of each section of both dies are inclined away from the paths of the punches solely in the directions normal to the mating faces 52 so that when after progressive grinding of the top faces 50 of the die sections the cutting clearances between the dies and the punches have become excessive, grinding of faces 52 to bring faces 40 closer together restores optimum cutting clearances. To compensate for the decrease in linear dimension of the top face of the die and block assemblies 15, 16 in the direction normal to the mating faces 52 which results from grinding the mating faces the top faces 51 of blocks 43, 45, 46 and 48 are ground also. Packing members (not shown) are inserted above thrust blocks (18) to which the die and block assemblies 15, 16 are screwed when the machine is re-assembled to force the die sections &c. further through the apertures (11), (12). An upper bolster (19), Fig. 2, not shown, guided on posts (21) carries a pair of notching punches (28) and a centre punch (30), to cooperate with dies 38, 39 respectively, and a spring-actuated stripper plate (23). A pilot pin (34) secured to punch holder (29) passes through an aperture (36) in blocks 43 and 49 and fixed stock guides (37) are mounted on bolster (10). The punches can be lowered for sharpening by substituting thicker pressure pads for pads (33) between the upper ends of the punches and the bolster (19).
