Title: Improvements in or relating to electromagnetic devices
IPC: H01H51/20
Filed: 1928-03-24
Abstract: 314,124. Siemens Bros. &. Co., Ltd., and Forceville, E. A. March 24, 1928. Selectors.-In order to increase the armature stroke of electro-magnetic step - by - step switches without necessitating an increase in the magnetizing force, a compound armature is employed consisting of a main portion and an auxiliary portion resiliently secured thereto the auxiliary armature when attracted carrying the main armature with it and decreasing the magnetic reluctance of the main armature so that it becomes attracted. As shown in Figs. 1 and 2 the main armature portion 6 is pivoted at 5 to the magnetic frame 4 carrying the electromagnets 1 and carries pivotally on a screw 7 the auxiliary armature 8 which is pressed towards the main armature by a spring 11 so that the magnetic projection 10 carried by the arm 9 projects through a perforation in the main portion towards a pole piece 2. On energization of the electro-magnet 1 the auxiliary armature is immediately attracted to the pole piece 2 or to a non-magnetic pin projecting therefrom carrying with it the main armature. The attraction of the auxiliary armature by causing a considerable decrease in the reluctance of the magnetic circuit of the main armature enables the main armature to be completely attracted during which movement a slight separation between members 6 and 9 occurs against the action of spring 11 as shown in Fig. 4. The armature in moving pushes along a slide 12 so that one of the teeth on its lower side steps along a rectilinearly-moving contact carrier 16. In moving, the projection on the carrier 16 rides over a tooth on a second ratchet 15 so that during the return movement of the armature the member 16 is held in its displaced position. the teeth of the member 12 riding over the projection on the carrier 16. The ratchets have laterally extending arms pivoted on a shaft 13 and are acted upon by springs 14, 17, the former returning the slide 12 after actuation and the latter holding the ratchet 15 against longitudinal movement. The armature is held against an adjustable stop 18.

Title: Improvements in or relating to brake systems
IPC: F02M31/04
Filed: 1932-04-01
Abstract: 385,163. Fluid - pressure brakes. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. April 1, 1932, No. 9368. Convention date, April 1, 1931. [Class 103 (i).] Fluid-pressure brakes comprise a cylinder 14, Fig. 1, on a tractor, operated by connection with a source of fluid-pressure by a manually operated valve 9 and a second cylinder 21 on a trailer, operated by connection to atmosphere and controlled by a valve 26 controlled by the pressure variation produced in the control pipe 27 of the first cylinder by the valve 9. The valve 26 comprises two controlling cylinders, the working space of the primary controlling cylinder 42, Fig. 3, being connected to the pipe 27 and the working space of the secondary controlling cylinder 19 being connected by a pipe 20 to the second brake cylinder 21. The secondary controlling cylinder is adapted to be connected by valves 49, 51 actuated by the. primary piston 41, to the atmosphere or to the source of pressure medium. The secondary piston 43 is loaded by a spring 53 and has a smaller effective surface than the piston 41 so that the braking effect on the trailer rises more quickly than on the tractor, and these pistons are subject on the left-hand side to atmospheric pressure. The trailer brake is spring applied and held off by vacuum produced through the valve 51 and pipe 17 from a vacuum reservoir 18, the vacuum in which is produced by the inlet manifold 11 of the vehicle engine. Vacuum produced by the manual valve 9 in the pipe 27 to operate the brake cylinder 14 produces operation of the valve 26 to close the valve 51 and open the valve 49 to connect the cylinder 21 to the atmosphere and apply the trailer brake. The consequent increase of pressure on the right of the piston 43 recloses the valves to give a lap position. In order that the movements of the piston 43 are unhindered by the piston 41 the pistons may be connected only in one direction loosely or by a weak spring. Piston 41 may be substituted by a diaphragm in a conical cylinder so that as the diaphragm moves to the right it bears more and more on the conical surface, thus reducing its surface as the pressure difference on it increases. The driver's valve 9, Fig. 2, comprises two valves 33, 34 adapted to be pressed on their seats by a spring 36 and operated by and displaceable on a rod 35 which is connected to the brake pedal by a lever 5 and a rod 4. On brake operation the lever 5 pivots about the end of a connection 6 to the brake shaft 8 and allows the atmospheric air valve 34 to close and opens the vacuum valve 33. The consequent movement of the brake shaft 8 recloses the valve 33 to give a lap position.

Title: Methods and devices for welding tubular parts and apertured parts together
IPC: B23K28/02
Filed: 1975-03-06
Abstract: 1491914 Welding by pressure DES USINES CHAUSSON SA 6 March 1975 [19 March 1974] 9474/75 Heading B3R A method of welding a tubular part 1 to a part 2, Fig. 2, having an opening aligned with the tubular part, the parts having mutually engaging portions bearing one against the other, comprises engaging an electrically conducting member 4 with one of the parts near the mutually engaging portions, passing a current through the member to heat it, causing relative displacement between the member and the parts over a limited distance to apply a pressure during welding to the mutually engaging portions, heat being simultaneously conducted to the parts from the member to cause welding together of the portions. The tubular part 1 and the part 2, such as a plate, may be of aluminium, aluminium alloy, copper, brass or steel, for example, stainless steel. The member 4 may be of graphite and has a neck for engaging the opening and tube 1 and a tapered portion 4b. The member is mounted by copper terminals 9, which are connected to an electrical source, on an insulated base 8 having columns 10 supporting a plate 11 which through nuts 13 applies pressure to the tube 1 by way of a clamp 11. A current passed through the members 4 causes heating thereof such that welding takes place between the parts, the relative movement between the parts during welding being limited by stops 13a on the columns 10. The tapered portion of the member causes a swaging at the welded joint. In another embodiment for welding a tube 25, Fig. 4, to an upstanding flange 24 of a plate 23, the member 26 has the shape of a ring with a tapered inner wall 27 to effect the swaging. The member is shaped at 28 to increase its resistance. A mandrel 29 placed within the tube may be connected to one of the terminals of the member to increase the welding efficiency and prevent deformation of the tube. The members may be split to facilitate fitting around the tube. A number of tubes may be welded simultaneously to the plate of a heat exchanger using a single heating member. The welding may be effected in a neutral or reducing atmosphere containing nitrogen or argon.

Title: Improvements in or relating to ratchet mechanism
IPC: B66F1/00
Filed: 1929-01-30
Abstract: 326,556. Beeston, J. P., and Pawsey, G. Jan. 30, 1929. Jacks.-Ratchet-and-pawl mechanism for lifting and lowering loads, applicable to lifting-jacks and winches &c., comprises a ratchet wheel 13, or an arcuate or straight rack, a holding pawl or detent 14 on a fixed pivot 15, and an operating pawl 18 carried by a lever 17 fulcrummed at 16 eccentrically to the ratchet wheel, both the detent and the operating pawl being connected by rods 20, 23 to spring controlling means located at the outer or free end of the lever and adjustable to two positions, (1) for lifting, in which both pawls are resiliently pressed into engagement, and (2) for lowering, in which the pawls tend to disengage, but, as the lever is rocked, are brought alternately into engagement at opposite ends of the stroke, being retained in engagement by the pressure of the teeth. In the form shown in Fig. 1, the connecting rods 20, 23, supported intermediately by pins 26, 26<a>, are coupled at their outer ends, through pivoted links 28, 31, to springs, such as 30, carried by a stay 34 pivoted on the lever 17. In the postion shown, the springs tend to retain the pawls in engagement for lifting. When, for lowering, the stay is rocked to the postion 37 indicated in broken lines, the springs tend to draw the pawls out of engagement, but the action thereof is limited by engagement of notches 32, 33 in the links 28, 31 with a stop 38 on the lever. Thus, when the lever is rocked, the pawl 18 engages the ratchet wheel at the lower end of the stroke, the detent 14 being held out of action, whilst at the upper end of the stroke the detent is brought into engagement, and as soon as it takes the load the pawl 18 is drawn out of action, descent of the load being thereby controlled. If the stroke is continued after the pawl or detent engages, the parts yield thereto without damage. The parts may be so proportioned that, when descent of a load has been started, the pressure on the pawls may cause the lever to rock and at the same time control the rate of descent in the manner of an escapement. In the form shown in Fig. 2, the outer attachments 39 of the springs 30 are fixed whilst the stop 38 is replaced by a lever 40 adjustable in a slot 42 by means of a link 41 and lever 43, the setting for lifting being shown in full lines. Specification 313,660 is referred to.
