Filed: 1936-11-23
Abstract: 487,860. Interlocked controllers. GORDON, C. J. Nov. 23, 1936, No. 32003. [Class 3S (iii)] A controller particularly for an electricallydriven vehicle comprises a switch 1-4 set by the driver to regulate the speed, a main switch 19 for opening and closing the motor circuits, and an interlocking device 12 coupled to and operated with the switch 19 so that in the off position of the switch 19 the switch 1-4 is free for setting and in the on position of the switch 19, the switch 1-4 is locked from movement. The speed switch comprises a rotatable disc 4 provided with one or more contact plates 3 co-operating with spring contact plungers 2 mounted on a stationary disc 1. The plungers 2 may have enlarged ends 10 which act as terminals and limit the outward movement. The spindle of the disc 4 carries a pointer 7 co-operating with a dial on the front of a cover 5. The disc 4 has a number of recesses in its periphery corresponding to its controlling positions, into which a plunger 12 is biassed by a spring 13, the plunger being withdrawn by the operation of a pedal 15 to open the main switch 19. The movable contact 18 of the switch 19 works in oil or grease in a sump 20. A lost-motion connection 21 enables a spring 23 to press the contacts of the main switch into engagement even though the plunger 12 does not seat properly in a recess. The pointer or setting lever 7 may be detachable from the spindle of the speed switch which spindle may terminate below the cover, so that unauthorized use is prevented. The controller may give series and parallel working of the motors, operate variable speed gears, and give electric braking. Specification 456,891, [Group XXXI], is referred to.

Title: Improvements in or relating to testing stands for gearboxes
IPC: F16H3/02
Filed: 1959-09-21
Abstract: 922,152. Testing gearing for noise. REGIE NATIONALE DE USINES RENAULT. Sept. 21, 1959 [Oct. 7, 1958], No. 32060/59. Class 80 (1). Apparatus for determining the sound level produced by a variable-speed gear for vehicles during its operation under various conditions comprises means for applying a driving torque to either the input or the output shaft of the gearing and applying a braking torque to the other shaft. A gear-box 8 is mounted on a cradle of the apparatus and its input and output shafts are operatively connected to shafts 6, 7 which are provided with electromagnetic eddycurrent type retarding devices 13, 14 and which are connectable through alternatively engageable synchromesh dog clutches 9, 11 to shafts 3, 2, shaft 2 being directly driven by an electric motor 1 and shaft 3 being driven through belt and pulley gearing. The transmission ratio between the shafts of the apparatus is such that when driving torque is applied to the output shaft it rotates at a lower speed than does the input shaft when driving torque is applied thereto. This is so that normal operating conditions are approached, since when engine braking is being used an intermediate ratio is generally selected. The reaction torque applied by the retarding devices 13, 14 can be varied.

Abstract: 340,676. Railway vehicles. BIRMINGHAM RAILWAY CARRIAGE & WAGON CO., Ltd., Smethwick, Staffordshire, and SCHOFIELD, N., 146, Hamilton Road, Handsworth, Birmingham. Oct. 28, 1929, No. 32635. [Class 103 (v).] Combined buffer and draw-gear.-In a combined buffing and draw-gear, particularly a central buffer coupling, for railway vehicles, of the kind in which the stresses are imparted to a spring or springs through the medium of a transmission member that also coacts with friction cams, a slidable spring casing or transmission member 14 is adapted to act directly on one or more cams 30 which have a frictional rolling movement in a friction head 21 and by their movement are arranged further to stress the spring system. In the construction shown a coupling-hook 6 is associated with a drawbar yoke 10 embracing the casing 14 and the latter is provided at its ends with rectangular flanges 16,18 whereby the casing is guided between channel members 3, Fig. 4, of the underframe. At its forward end the casing 14 is furnished with diametrically opposed channels 19 to receive and guide channel-shaped projections 20 on the friction head 21, while the projections 20 in turn serve as guides for lugs 25 on a follower washer 24. Located in horizontally disposed pockets in the head 21 are flat cams 30 of substantially semicircular cross section as shown in Fig. 3, one edge 32 being in rolling contact with the washer 24, a second edge 31 being in frictional sliding contact with the internal surface of the head 21, and a lug 33 engaging the front flange 18 of the casing 14. When the gear is in operation, e.g., in drawing, the casing 14 is drawn forward by the yoke 10 from fixed stops 17 against the action of the control spring 28, movement being simultaneously imparted through the lugs 33 to the cams 30 which are displaced against the frictional resistance between themselves, and between themselves and the head 21, such resistance increasing with increase of the drawing effort. The surface 32 is so shaped that at the same time the follower washer is forced rearwards to a slight extent, increasing the compression of the spring 28, while the point of contact between the cam and the washer 24 moves away from the lug 33 and thereby increases the leverage effect of the force on the lug.

Abstract: 1339932 Modulating light PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 July 1971 [17 July 1970] 33057/71 Headings H4F and H4T In an optic relay, e.g. of the type described in Specification 1,160,923, wherein a Pockels crystal is scanned by an electron beam, thereby modulating across its area a light beam transmitted through the crystal in accordance with a video signal supplied to the relay, the crystal is subject to thermally induced or other mechanical stresses which produce undesired birefringence variations in the crystal and hence undesired modulation of the light beam. The most common form of stress is said to be rotationally symmetric and may be compensated by adding to the video signal a compensating signal of the form v=kxy or kr<SP>2</SP> sin 2# in Cartesian or polar co-ordinates respectively, and measured from the centre of symmetry of the stresses. For a television type scan of successive horizontal lines, v takes the form of a sawtooth of line frequency with a slope modulated at frame frequency, and may be produced by the circuit of Fig. 4. Positive and negative line frequency sawtooth voltages x, ( - x), are variably divided by the series combination of a capacitor 1, (2), and a variable capacitance diode 4, (5), controlled by frame frequency sawtooth waveforms y, ( - y), and the two components are mixed at 3. A bias supplied by potentiometer 6 renders the ordinate of the centre of symmetry of the correction voltage v coincident with that of the mechanical stress, and a component proportional to y is passed from a potentiometer 7 to mixer 3, so that the abscissae of v and the mechanical stress coincide. The combined video and compensating signal may be applied between a grid and a transparent layer on opposite sides of the crystal, or may be used to modulate the electron beam intensity. In the latter case a gamma correction may need to be performed on the combined signal.
