Title: Improvements in auxiliary endless tracks for motor and other vehicles
IPC: B62D55/02
Filed: 1934-01-24
Abstract: 432,044. Endless - track vehicles. GALLEGOS, O. P., 368, Uxbridge Road, Acton, London. Jan. 24, 1934, No. 2409. [Class 79 (i)] Comprises the provision of an auxiliary endless track for each back or front wheel or for all wheels of a motor or other vehicle, the said track being raised and lowered relatively to the wheel and the ground, the line of contact of each track with the ground lying across a transverse line drawn through points coincident with the normal points of ground contact of the wheels. The tracks are driven from the wheels or the engine and are used for travelling on rough ground and also for braking, means being provided for raising and lowering the tracks relatively to the ground so as to take all or part of the weight. In the construction shown in Figs. 4 and 5 applied to a steering wheel 17, the wheel axle 17<a> has a frame 25 rotatably mounted thereon, this frame being provided with rollers 30 for an endless chain track 31 which also passes round a chain wheel 24 loose on the wheel axle. The chain wheel can be clutched to the road wheel by a clutch 18 controlled by a rod 23. The track frame 25 is rotated on the wheel axle, so as to bring it into use as shown in full lines in Fig. 5, or out of use as shown in dotted lines at x, by means of a link 32 and an arm 33 on a shaft 34 operated by the driver. The rod 23 controlling the driving clutch, and the shaft 34 are preferably operated by a single control lever, and this lever may control the tracks of two or four wheels. When the tracks are on the ground the ordinary wheel brakes may be applied to brake the tracks, or separate brakes may be provided for the tracks. The tracks may be driven through change-speed gearing so that their speed may be varied as they approach the ground. Modifications are described in which (1) each track passes round rollers on a shoe mounted eccentrically of the wheel axle, so that as the shoe is rotated to lower the track to the ground the track comes between the wheel and the ground and supports the wheel and is driven by it, and (2) the rollers for the track are adjustably supported on the track frame, so that the contour of the track can be varied. Two tracks side-by-side may be provided for each wheel. The track and its frame and other parts are preferably combined with the wheel to form a readily detachable unit. The tracks may be automatically brought into use when a tyre is deflated, an electric circuit being completed which causes the track-controlling means to be operated.

Drawings to Specification. [Class 39 (i)] A lamp, more particularly for projection purposes, comprises one or more fixed incandescent electrodes and a filling of mercury vapour which is unsaturated during normal operation, the consumption of energy per cm. of the discharge path exceeding 100 watts. The load depends upon the softening temperature, and the dimensions of the bulb. The electrodes preferably are located vertically one above the other but a magnetic field may be used to suppress the curvature of a horizontal discharge path. The lamp may be provided with two oxide-coated helically-wound electrodes which may be heated directly or indirectly or by the discharge. Glass is applied to the leading-in wires and is fused to the envelope which may consist of quartz or the material known under the Registered Trade Mark "Supremax." The filling of a lamp of which the Specification gives dimensions of the envelope and distances between the electrodes &c., consists of argon at 5 mm. pressure and 1 gme. of mercury. To obtain a uniform thermal distribution over the envelope, the distance between the lower electrode and its seal is smaller than that between the upper electrode and its seal. The lamp may be housed within an envelope containing gas at a pressure greater than atmospheric.

Title: Improvements in and relating to the application of ceramic transfers or prints to pottery and like goods
IPC: B44C1/16
Filed: 1945-02-09
Abstract: 571,548. Transferring designs. BOULTON. Ltd., W., and LEWIS, R. T. Feb. 9, 1945, No. 2629/44. [Class 100 (ii)] In apparatus for applying ceramic transfers or prints to pottery, the ware is pressed between dies formed of pads or blocks of slightly resilient material 13, 16 of hard rubber or gelatine with a facing or loose pad 14, 17 of a more highly resilient material such as sponge rubber, one of the dies being shaped to accommodate the articles such as flat plates, and the other die may be formed of convex formation so as to act progressively from the centre outwards. The articles 41, Fig. 3, are advanced to operative position by being placed on the lower band 23 of a conveyer of flannel which is advanced intermittently to bring the articles into printing position. The articles are placed on a pivoted support 38 situated from the pads a distance which is a multiple of the extent of each intermittent motion of the conconveyer. This motion is obtained by a sprocket 27 which is driven by a free-wheel drive from a chain 30 which is operated by a lever 33 and a peg 34 on a wheel 35 adapted to raise a weight 31 on the chain 30 a given distance. When the peg releases the lever 33, the weight 31 drives the sprocket 27 and advances the conveyer. The pressure for transferring the design is produced by reciprocating the upper pad by crank mechanism, or by hydraulic means, and the resiliency of the action is enhanced by the interposition of the two layers of the flannel conveyer.

Filed: 1916-02-23
Abstract: 100,172. Wilcox, R. March 18, 1915, [Convention date]. Vehicular and like lamps, directing.-Vehicle head-lights or other lamps are rotated about a vertical axis by means which includes a tube 56, Fig. 5, mounted for rotation about a vertical axis, while movement of the lamp about an horizontal axis is effected by means of a lever 24, which is mounted on one end of the tube 56 for rotation about an horizontal pivot 46 and serves also as the means for rotating the tube. The lamps can thus be moved either about the vertical axis or the horizontal axis, as desired, by a corresponding movement of the single operating member 24, the cables 21, 22, through which the movements of the lamps are effected, passing respectively around and through the tube 56. In the form shown, two lamps 15 are each mounted in bearings 31, Fig. 4, on a yoke 29 carried by a vertical tube 25 rotatable within a standard 18 fixed to the vehicle. Rotation about the bearings 31 is effected by means of a cable 22 secured to a lug 40 on the lamp and passing over pulleys 41, 69, 68 to a point 67, Fig. 2, where the cables 22 from the two lamps are connected to a cable 66 secured to the operating-lever 24. The lamp tends to be returned to the normal position by compression springs 35 on a pair of pins 33 pivoted to the lamp at 32 and passing through lugs 34 on the rotatable tube 25. The lever 24 is provided with a pawl 49 held in engagement with a pair of ratchet racks 48 by a spring 55 controlled by a push 52. For rotation about a vertical axis, a cable 21 is secured to pulleys 43, 63 at the lower ends of the rotatable tubes 25, 56.

Filed: 1917-02-27
Abstract: 108,276. Turner, W. V., and Thomas, T. H. Sept. 6, 1916, [Convention date]. Addition to 103,959. Electric braking; systems for continuous-current motors only.-In a regenerative motor control system of the kind described in the parent Specification in which four series motors are successively connected automatically during regenerative braking in parallel, in series-parallel, and in series as the speed of the machines de. creases, the fields of the motors are permanently connected in series with their armatures and during the initial stage of the braking the machines are connected in a closed circuit con. taining a high resistance until the voltage built up from the residual magnetism of the fields is greater than that of the line when the machines are automatically connected to the line The speed of the machine is limited during the regenerative braking period by the automatic application of the air brakes when the speed exceeds a pre-determined adjustable value. In the arrangement shown, the connexion of the machines to the line is controlled by a switch 16, Fig. 1, operated by fluid pressure. In all positions of the controller except the braking position, a piston 16<b>, controlling the switch 16, is under fluid pressure controlled by a valve 18 which is operated from the braking controller 2; and the cylinder of the piston 16<a> is open to exhaust so that the switch 16 normally occupies its left-hand position. When the controller 2 is turned to the braking position shown, a lead R is connected to line through a lead T so that the booster motor 4a and the coil 14<b> of the valve 14 are energized directly from the lead R, while the coil 9<b> of the valve 9 is energized from the lead R through the switch 16. The machines A<1> F', A<2> F<2>, A<3>, F<3>, A<4> F4then operate as generators and the current generated passes through the booster 4 and a lead S to the switch 16 where it divides a portion flowing through a high resistance X and a portion through the coil 14a of the valve 14. The movement of the controller 2 to its braking position places the cylinder of the piston 16<b> to exhaust but no fluid is admitted to the cylinder of the piston 16a during the initial stage of the braking as the energized coil 14<b> maintains the valve 14 in its original position. The valve 9 is held closed by the energized coil 9<b> to prevent the application of the air brakes. When the voltage of the machines reaches a pre-determined value above that of the line, the coil 14a overcomes the coil 14b to cause the valve 14 to admit fluid to the cylinder of the piston 16<a> when the switch 16 is moved to the position shown to convert the machines to line. The valve coils 14a and 9b are de-energized and the brake valve coil 9<a> energized by the operation of the switch.
