IPC: B62D11/04
Filed: 1938-11-12
Abstract: 521,346. Control of two motors; controllers. OGILVIE, B. C. H. Nov. 12, 1938, No. 32989. [Class 38 (iii)] [Also in Group XXXI] In a vehicle having the road wheels or equivalent members on each side independently driven by reversible electric motors, a single control lever mounted for universal movement controls rheostats of both motors in such a manner that the speed, the steering and the reversing of the vehicle are controlled exclusively by the said lever. In the construction shown the control lever 1 is mounted on a transverse shaft 2 rotatable in a frame 4 mounted on a longitudinal shaft 3. The lever 1 has arms 5, 6 working over rheostat contacts 7, 8 and the shaft 3 has arms 11, 12 working over rheostat contacts 13, 14. The electrical connections are such that when the lever 1 is moved fore-and-aft the arms 5, 6 are moved over the contacts 7, 8 and both wheel motors are driven at the same speed and in the direction corresponding to the movement of the lever. When the lever is in addition given a lateral movement the frame 4 is rocked and the arms 11, 12 are moved over the contacts 13, 14 to speed up one-motor and reduce the speed of the other so as to steer the vehicle. According to the Provisional Specification there are only two rheostats controlled by a handlever acting through screw and bevel gearing on arms mounted on two co-axial shafts. Thus, (1) if the hand lever is moved forwardly or back the two control shafts are rotated at equal speeds in the same direction and' both motors drive the vehicle forward or back in a straight line, (2) if the hand lever is moved transversely from its neutral position the two control shafts are rotated in opposite directions and one motor drives its road wheel forwards and the other motor drives its wheel backwards so that the vehicle rotates about its own centre, and (3) if the hand lever is given both longitudinal and transverse movements the two motors will be differentially controlledand the vehicle will travel at a speed and in a direction corresponding to the position of the hand lever.

[Also in Group XXVIII] An hydraulic pipe-testing apparatus comprises two sealing heads 13, 14 for supplying pressure fluid to one end of a pipe to be tested and for sealing that end from atmosphere and a further sealing head 19 for sealing the other end of the pipe, the heads 13, 14 being movable in a direction transverse to their axes between two positions in each of which one of them, e.g. head 14 as shown, is coaxial and co-operable with the head 19 to permit the testing of a pipe 12<SP>1</SP>, whilst the other head, e.g. 13, is in a position to receive another pipe 12 to be tested. Conveying elements 1, 2 are slidable on guide bars 4 mounted on stands 5 and are provided with pipe conveying rollers 6, 8 and pipe transverse lifting bars 7, 9 rotatably operable by cranks. The element 2 is also provided with pairs of pipe feed rollers 10, 11 rotatable about their vertical axes. The sealing heads 13, 14 are mounted on a turret 15 rotatable in a housing 17 slidable on the guide bars 4. The sealing head 19 is mounted in an axially movable housing 20. The axes of the rollers 6, 8, 10, 11 and of the heads 13, 14, 19 each lie in a plane inclined to a horizontal plane extending through the turret 15. Operation.-Through the control of timing relays, after a pipe 12 has been sealed at one end by the head 13, it is flushed with water supplied through the head 13 and transferred by the lifting bars 7, 9 to the position 12<SP>1</SP> in front of the sealing head 13 which at this moment is in a retracted position, the relative position of the heads 13, 14 being reversed due to rotation of the turret 15. Supply of water to the head 13 is cut-off, the housing 20 shifted until the head 19 seals the other end of the pipe and water is then pumped through the head 19 into the pipe for testing. After testing, the housing 20 is shifted back to its original position to disengage the head 19 from one end of the pipe and the rollers 11 are operated to shift the pipe to disengage the head 14 from its other end so that water can run out of the pipe. A new pipe 12 which has been fed along the rollers 6, 8, 10 and inserted into the head 13 may then be transferred to the testing position, whilst the tested pipe is lifted from that position and conveyed away in a transverse direction such as by rolling it down over inclined guide rails 25, Fig. 2, with which a collecting trough 26 may be associated.

Abstract: 447,761. Photographic shutters. VOIGTLANDER & SOHN AKT.-GES., 7, Campestrasse, Brunswick, Germany. Nov. 20, 1934, No. 33411. Convention date, Nov. 23, 1933. [Class 98 (i)] Relates to a shutter in which, for effecting time exposures, an intermediate member geared with the shutter blade operating member is moved by a hand operated device into a position where it is retained by a catch, the catch being released by a second operation of the hand operated device, and consists in the particular construction of hand operated device described. The lens opening 37 is normally closed by blades 7 pivoted at 38 to the annular plate 1, and is actuated by the member 6 which has pins 40 engaging in slots 39 in the blades. Teeth 5 on a part of the 'circumference of the member 6 are in engagement with teeth 4 on an intermediate disc 2. A coil spring 34 opposes the movement of the disc 2 to open the shutter. The hand device comprises a cylinder 14 containing a plunger 17 operated by a cable against the opposition of a spring 22 and a rod 20 which moves in a slot 25 in the head 24, and is integral with a disc 21 allowing lateral swinging movement of the rod 20. The intermediate member 2 is formed with a concave arm 23. When a " time " exposure is to be made, the rod 20 is actuated, engages the arm 23, and rotates the disc 2 to open the shutter. The disc 2 is held in the extreme position by the nose 12 of a latch 9 engaging a nose 13 on the disc 2. The movement of the disc has moved the rod 20 laterally, but when this rod is withdrawn it returns to its original position. Then when it is moved forward again, it engages the concave arm 11 of the latch 9, releases the nose 13 and allows the disc 2 to turn and close the shutter. For a " bulb " exposure, the latch 9 is retracted by a hand operated cam ring so that it does not engage the nose 13. If it is desired to make an instantaneous exposure, a master member 26 is brought into operative connection with the shutter ring 6. The disc 2 is mounted on a pair of links 32, Fig. 5, so that it can be swung out of engagement with the blade operating ring 6 and into engagement with the teeth 30 of a pivoted pawl 28 which is holding the master member. Rotation of the disc 2 by the rod 20 then swings the lever 28 to release of the master member and open the shutter for a predetermined time. Specification 365,753 is referred to.
