Abstract: 1,092,593. Shovel loaders. ATLAS COPCO A.B. March 17. 1966 [April 5, 1965], No. 11820/66. Heading B1F. A side dumping shovel structure for a front loader involves a vertically swingable boom transversely supporting a guide beam along which may be traversed a shovel from a central loading position that does not permit of tilting of the shovel about an axis extending transversely of the length of the beam to a side position where it can be tilted about such an axis. The beam comprises parallel, interconnected, inwardly facing U channels in which run two sets of wheels disposed at either end of the bottom of the shovel. Openings are so formed in the upper flanges of the channels that only one set of wheels at a time can leave the channels through the openings when the scoop is correctly placed on the beam to permit of jack-actuated side dumping by the shovel.

Title: Motor vehicle brake
IPC: F16D51/66
Filed: 1956-04-19
Abstract: 782,810. Servo-brakes. ECKARDT, K., and ECKARDT, J. April 19, 1956, No. 12002/56. Class 103 (1). In a vehicle brake arrangement in which an auxiliary brake acts on an element of the vehicle which is rotated during travel such that rotation of the part of the auxiliary brake which takes up braking torque actuates the main wheel brakes of the vehicle, the force and movements of the auxiliary brake are transmitted by a pivotable force take-off member having an axis parallel to the axis of the auxiliary brake; this member bearing simultaneously against two working surfaces on the auxiliary brake in the rest position of the brake. In the embodiment illustrated in Figs. 4, 5 and 6, the auxiliary brake engages on the right rear wheel of the vehicle and during forward travel, the working surface 31 of the shoe carrier 22 of the auxiliary brake rotates about shaft 21 and moves to the left pushing the working surface 32 of the pivotable force take-off member 27 before it, as shown in Fig. 5, to actuate tension-rod 30 connected to the main brakes. During reverse travel, the working surface 31 moves away from the force take-off member 27 and the working surface of cam 33 provided on brake shoe carrier 22 rotates the force take-off member 27 via working surface 35 of the latter in the same direction of rotation as is the case in forward travel. Projection 24 on brake shoe carrier 22 bears against abutments 25 or 26, depending on the direction of rotation of the brake shoe carrier, and are so positioned as to limit the angle of rotation so that the angle 38 through which the force take-off member 27 rotates is the same in either forward or reverse travel of the vehicle. In practice, however, the brake shoe carrier 22 reaches the abutments 25 or 26 only if the main brakes fail in consequence of rod fracture, pipe fracture or the like. Shaping of the working surfaces 33 and 35 after the manner of tooth flanks allows any desired transmission ratio between the auxiliary brake and force take-off member. A further embodiment is disclosed in the Specification wherein the auxiliary brake engages with the main gearing shaft and actuates the main wheel brakes.

Title: Improvements in x-ray apparatus
IPC: G21K1/04
Filed: 1952-05-12
Abstract: 706,378. X-ray apparatus. ELECTRONIC & X-RAY APPLICATIONS, Ltd., TUNNICLIFFE. E. A. J., and WAY, R. F. May 12, 1952, No. 12048/52. Class 98(1) In a shutter for X-ray apparatus, the movable plates are coupled to a continuously operable driving component through a resilent slipping drive device, the resilient component of which is loaded by drive reaction set up by movement of the plates to their closed position or their arrival at that closed position and which acts to hold the plates in that position when drive ceases. As shown in Fig. 1, shutter plates 1, la, are slidable'in guides 3, 4 over an X-ray transparent window 24 in the bottom of a tray 23, and are connected to pivoted levers 7, 8 so as to move equally in opposite directions. Lever 8 is bolted to a pinion 10. An electric motor 17, Fig. 4, drives a shaft 15 through gearing 16. A worm 14 rotatably mounted on shaft 15 is held between friction discs 18, 19 urged towards each other by springs 20, 21. When the shutter plates are being closed, worm 14 drives a pinion 13 fast with a pinion 12 driving pinion 10. When the plates abut, worm 14 moves along shaft 15, compressing one of the springs, until the friction discs 18, 19 slip. When the motor is switched off the spring action on worm 14 presses the plates together. Similar action takes place when the plates have been separated as far as they will go by reversing motor 17. A second similar pair of plates and driving means is mounted in a tray similar to 23, and the trays are mounted with their open ends together and with the directions of movement of the two pairs of plates at right-angles. The driving motors are operated by separate switches. Alternatively, both pairs of plates may be driven by a single motor. The shutter assembly may be mounted, together with an X-ray tube and a fluorescent screen, on a movable carriage in an X-ray apparatus.

Abstract: <PICT:0683428/IV (a)/1> <PICT:0683428/IV (a)/2> <PICT:0683428/IV (a)/3> In the wet-spinning of artificial filaments, e.g. from viscose, the spinning solution is passed from a stationary filter through a coiled, heat-exchange tube immersed in the coagulating bath to the spinneret and the coiled tube is pivotally supported with respect to the stationary filter so as to be swingable with the spinneret into and out of the coagulating bath.  As shown (Fig. 2), the coiled tube 30 and spinneret 32 are attached to a pivotally supported bracket 10, an upward movement of which serves to remove them from the spinning compartment 39.  The filter 9 is stationary and communicates with the coil through a passageway 15 in the bracket.  The spinneret, coil and filter are all separately detachable from the assembly.  Coagulating liquid enters the spinning compartment 39 (Fig. 4) from a de-aerating chamber 38 and leaves through a drainage compartment 37 provided with a vertically adjustable constant head-overflow pipe 43.  The pipe 43 (Fig. 2) comprises two members 55, 56 in threaded relationship, the lower member being detachably seated in the drainage outlet 59 so as to facilitate, when necessary, rapid drainage of the spinning compartment.  A strainer 48 retains solid buoyant material in the spinning compartment.  The filter 9 (Fig. 5) comprises a filter element 64 of, for example, a porous metal such as sintered stainless steel, spaced from an inner core 65 and an outer cover 66, the whole being detachably secured to a base 75. To effect removal of magnetically attracted material from the spinning solution, the core 65 houses a magnet 82.  In addition, a magnet may surround or be included in the cover 66.
