Title: Improvements in or relating to wheeled vehicles
IPC: B62D11/04
Filed: 1937-04-16
Abstract: 479,814. Motor vehicles ; endless track vehicles. ALVIS-STRAUSSLER, Ltd., and STRAUSSLER, N. April 16, 1937, No. 10927. [Classes 79 (i), 79 (ii), and 79 (iii)] [Also in Group XXXII] In an endless-track or wheeled vehicle each driving wheel 16 is carried on a bogie pivoted at 28 on a bracket 26, each bogie comprising a hollow arm 30, which contains the final drive gears and on which the wheel is mounted, and another arm 31 also pivoted at 28 which carries an idler wheel or ground roller 20 and is connected by spring or cushioning means 33 to the main arm 30, so that the two arms are deflected relatively to each other by downward pressure on the pivot. Endless tracks 14 may be passed over the driving and idler wheels as shown, adjustable rollers 60 being movable up and down by rack gear to tension the tracks. There may be driving wheels at front and rear as shown in Fig. 1, or at the front only as shown in Figs. 3 and 4. In the latter construction the rear pairs of wheels 21, 24 are mounted on bogies or beams 44 pivoted at 45 on cranked arms 46 which are connected by torsion bars 47 to a differential gear 48 having a stationary central part. Thus, when the wheels at one side rise over an obstacle the torsion springs tend to press down the wheels at the opposite side, so that the vehicle body remains level. The pivots 28 of the driving wheel bogies are nearer the idler wheel centres than the driving wheel centres, so that the load is greater on the idler wheels than on the driving wheels, in order to facilitate steering. Stops 39, 40 limit the movement of the bogie arms 30. In order to impose extra load on the driving wheels when desired, the idler wheels 20 may be raised clear of the ground by means of eyebolts 41, Fig. 5, pivoted to the arms 31 and adjusted by nuts 43 engaging fixed brackets 42. Alternatively, an additional spring may be caused to act with adjustable pressure on each arm 30. The vehicle is driven by two engines 12, 13 each driving the wheels or tracks at one side of the vehicle through a clutch and gearbox, a transfer gear-box 35 which may include change speed, or reversing or differential gear, and universal joints 36. In cases of emergency either engine may be arranged to drive both sides of the vehicle. Steering is effected by varying the speeds of the two engines. Each driving wheel has two flanges 50, 51, secured together by bolts 56 and gripping a solid rubber tyre 52 between them. Pins 55 on the flanges engage the links of the endless track. When the tyre tread becomes worn shims 53, 54 between the flanges are removed, and the increased pressure of the flanges deforms the tyre and causes it to project beyond the flanges again.

Filed: 1920-04-20
Abstract: 146,932. Soc. des Moteurs Gn¶me et Rh¶ne. July 4, 1919, [Convention date]. Fluid-friction vibration-dampers.-A shock-absorber for vehicles comprises a casing fixed to the frame and enclosing in a liquid bath two pinions gearing together, one of which is so disposed with respect to the axle that partial rotatory movement occurs under shock. As shown in Fig. 1, m is the casing enclosing the two pinions a and b, one of which is secured to an arm c, actuated by a lever d connected to the axle. The pinions are mounted with a certain amount of play, and the teeth are provided on one side with grooves i, Fig. 2. Under shock, the lever d is raised, and the pinion b rotated, causing part of the liquid to flow from f to h against the resistance due to the narrow passage. On the return movement the smooth faces of the teeth come into contact, and the liquid can only return by leakages allowed to secure a normal mechanical working of the pinions, whereby the descent of the lever is slower than its ascent. In a modification, the gearing comprises a pinion gearing with an internally toothed crown, both of which may be partially or wholly provided with teeth.

Title: Data transmission system for more than two subscribers
IPC: H04L1/14
Filed: 1966-03-15
Abstract: 1,143,746. Data transmission systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 15 March, 1966 [17 March, 1965], No. 11263/66. Heading H4P. In a system in which the same data is transmitted to at least two receivers E and in which errors are corrected by repetition, the receivers E are connected to the transmitter S by one or more transmission lines L which are returned to the transmitter. There may be a plurality of receivers in series on each transmission line loop. Errors in transmission are detected by returning to the transmitter the data from the final receiver on each loop for comparison with the data as originally sent on that loop. Alternatively, the return signal may comprise signals derived from the final receiver, e.g. redundancy signals. Each receiver may correct errors prior to passing the corrected data to the following receiver. If the errors cannot be so corrected the data is deliberately mutilated, to ensure that repetition occurs. The receiving unit of the transmitter may have means to detect correct data on a loop and itself to transmit such correct data to any other loop containing a receiver which detected error in that data, the transmitter being stopped during this action, or may have means to compare corresponding data on each loop and to determine, by majority decision, which loops transmitted correctly.

Abstract: 236,523. Gleason Works, (Assignees of Bullock, E. W., and Slade, A. P.). July 5, 1924, [Convention date]. Gear-cutting. - A geargrinding machine is provided with mechanism for trueing the grinding-wheel automatically after a predetermined number of teeth have been ground on the blank. The blank support is mounted in a head on a table 6 which is angularly adjusted by rack and pinion gearing and is itself supported on a carrier 9 oscillated on ways 10 through a link 11 operated from a shaft 12. The translatorv movement thus imparted to the blank is combined with a rotary movement to give correct rolling by means of a segment rolling on a stationary segment comprising two portions 14, 15. The support 22 of the annular grinding-wheel 20 is movable on a bed 2 by a screw 24 driven through intermittently-operated worm-gearing 28. The worm-shaft 29 carries a ratchet-wheel 30 actuated through a pawl 31 and pivoted arm 34 from cams 37 on an intermittently-rotated cam wheel 38. The cammechanism is so arranged that after every fourth tooth-forming operation the ratchet mechanism is actuated to move the grinding-wheel towards the. dressing-mechanism, whereupon the trueing operation is effected during the time that the blank is being indexed. A pinion 40 is driven through gearing from a reciprocating rack 45 operated by a telescopic shaft 47 which, when the arm 34 is moved by a cam 37 to the position shown in Fig. 24. is reciprocated by a cam 53 in a rotating cam wheel 54. The pinion 40 is mounted on a shaft 60 which is arranged to reciprocate a curved rack which through a pinion gearing reciprocates inclined slides 63 carrying spherical dressing-wheels 69 for trueing the sides of the wheel. Each dressing-wheel is rotatably mounted in a holder 72, Fig. 15, which is con. nected through bevel and ratchet gearing to a spur wheel 79 running on a stationary rack 80, the arrangement being such that as the slides 68 reciprocate, the dressing-wheels are rotated continuously in one direction about the axes of the supports 72. The edge of the grinding-wheel is simultaneously dressed by a wheel 83 mounted on an arbor which is oscillated from a rack 63 by gearing 84, 86. The machine is driven from an electromotor 90, the belt 93 driving the grinding wheel passing over tensioning-pulleys 94.
