Title: Device for dissipating the energy surge incident to an abrupt stopping of a driven element in a motor-driven power transmission
IPC: F16H35/10
Filed: 1939-04-05
Abstract: 527,508. Slipping clutches. WALKERTURNER CO., Inc. April 5, 1939, No. 10639. Convention date, April 19, 1938. [Class 80 (ii)] A helical gear 9, meshing with an axially-fixed helical driven (or driving) gear 7, is normally maintained in frictional engagement with the conical surface of a member 8, fixed to its shaft, by means of a spring 14 acting in opposition to the action of the gear teeth, the reaction between which tends to separate the conical surfaces. The angle of the cone is approximately 15 degrees, and the helix angle and the strength of the spring 14 are such that the frictional connection is maintained under all overloads to which the transmission is normally subjected, but if the driven element is suddenly arrested the frictional connection is momentarily broken by axial movement of the gear 9 against the action of the spring 14 so as to dissipate the resulting surge of energy, after which the spring immediately re-establishes the frictional connection and causes the driving motor to stall. In the drive for a rotary saw 32, which is liable to be suddenly stopped by pinching by the work, the member 8 is fixed on the shaft 37 of the motor 36 and the gear 7 on the saw mandrel 1. The spring 14, in the form of a slotted disc, is fixed to the end of the shaft 37 by a stud 37a and bears against the side of the gear 9 through a friction-reducing washer 10 centred on a washer 11 fixed by the stud 37a.

Abstract: 1460003 Indoor games EMI Ltd 21 Feb 1974 [6 March 1973 1 May 1973] 10685/73 and 20635/73 Heading A6H [Also in Division H4) In apparatus for playing games involving a (colour) television receiver at least one "mark" is displayed the speed and direction of movement of which are adjustable by control means operated by a player additional means being provided which over rides the control means and also controls the motion of the mask. Fig. 1, shows one embodiment concerned with the display of a race track and of a number of "spots" representing cars which move around the trace under player control. The track display is produced by a generator 10 and the car display by a generator 12 supplied with the field and line synch. pulses (generator 10) and with line and field sawtooth waves from a circuit (outline A) which generates colour television signals suitable for insertion into the aerial socket of a domestic black and white or PAL colour television receiver 27. The velocity of the spot in the two-dimensional plane of the screen is controlled by joystick coupled potentiometers 13, 15 and the outputs of generators 10 and 12 are displayed in selected colours determined by selected inputs to a colour encoder 11. A suitable coloured background may be provided by a generator 21. Additionally suitable sound effects may be provided by an effects generator 23. In operation, a coinciding detector 19 provides an output when the car is not coincident with the track i.e. when it leaves the track and this output controls generator 12 such that the car now only moves at a slower rate than its speed along the track. Generator 12 may also include time constants to simulate finite rates of acceleration braking and skidding at corners. One or more duplicated car generator(s) and coincidence circuit(s) may provide signals on other respective inputs such as line 20 to colour encoder 11 so that a second car or cars is/are displayed in a different colour(s). Circuits may be provided (1) to count the number of laps completed by each car (2) to detect collisions and initiate "bounces" (3) to measure the number of times a car leaves the track in a given time and (4) to provide a display of randomly switched traffic lights. The game may, alternatively, consist in the players controlling respective spots to chase one another the attainable speed being arranged to vary with position in a pseudo-random manner, coincidence of the spots causing them to disappear or to merge and change colour. Preset potentiometers 17, 18 may supply bias voltages to lines 14, 16 to simulate "drifts" e.g. cross-winds or up-and-down hill conditions. Such bias voltages may, alternatively be time varient and be supplied by suitable amplifiers. The display may also represent yachts and marker buoys, sand banks and coastlines.

[Class 80 (i).] Relates to means for automatically tensioning a driving belt in accordance with the load of the kind wherein a gear wheel 13 is secured to a driven (or driving) shaft 11 on which is freely hung a housing 16 supporting a driving shaft 22 carrying a belt pulley 31 and a pinion 30 meshing with the gear wheel so that its rotation will cause the pinion to make an epicyclic movement about the gear wheel until the belt 40 is tensioned to the correct degree. The invention consists in the provision of ball or roller bearings 21, 23 for the driving-shaft 22, the bearings being arranged on each side of the pinion in recesses in bosses on the housing 16 to take radial and end loads. In the form shown in Figs. 1 and 2, the outer bearing races are formed in two parts outwardly flared to facilitate assembly and held together by retaining rings 26. They are held in theirrecesses by end plates 33, 34. The inner race of the bearing 21 is bolted against a shoulderformed by the pinion 30 by an end-nut 35 which takes the axial thrust. To reduce overhang of the shaft, the rim of the pulley 31 overlies the bearing 23. In a modification, also shown, both the pinion 30 and the pulley 31 are arranged between the bearings 21, 23, instead of only the pinion as shown in Fig. 1. Single row ball bearings are used and these are supplied with oil through plugged holes in the closed outer end-walls of the housing bosses. Oil is also supplied to a groove in the keyed bearing sleeve 10 which supports the housing 16. The latter has bell-shaped reinforcing- arms on the side remote from the gear wheel to support the bearing 23 and is retained endwise on the sleeve 10 by a spring clip instead of by the boss of the wheel 13 as shown in Fig. 1. The boss for the bearing 23 is detachably secured to the housing by screws. The arrangement may be used with change-speed gearing.

Electric spark-discharge apparatus includes at least one semi-conductor element 1 which is modulated to produce time-spaced discharges between the workpiece 4 and electrode 5. Current pulses of rectangular waveform are stated to be produced and the sparking occurs between pulses. The semi-conductor element may be a magneto-resistance unit whose resistance element 1A is in series with a condenser 2 and whose field excitation winding 1B is connected to a pulse generator 6 or alternatively to a time delay network. The resistance unit may have an additional excitation winding, Fig. 3 (not shown), in series with the resistance element 1A. In another embodiment, Fig. 2 (not shown), alternating current is used and the pulse generator derives its triggering signal from this supply. An additional magnetoresistance unit 8 may be included in the discharge circuit, Fig. 4, with its excitation winding 8b connected through a rectifier 9 in shunt with the condenser 2; alternatively, both units may be modulated by a common pulse generator, Fig. 5 (not shown), whereby the triggering pulse is dependent upon the current in the discharge circuit. Transistors of the point contact or junction type may be used instead of the magneto-resistance units. In one embodiment, Fig. 7, transistors 19, 22 of the P-N-P type are connected respectively in the charging and discharge circuits. Transistor 19 is modulated by a pulse generator 6 and transistor 22 is coupled to the pulse generator through a time delay device 24. Specification 637,872 is referred to.

Abstract: 352,497. Hydraulic springs. AMMIRANDOLI, D. and BALDI, C., 228, Via Silvestri, Prato, Toscana, Florence, Italy. April 8, 1930, No. 11207. Convention date, April 11, 1929. [Class 108 (iii).] In vehicle suspension or other shockabsorbing systems in which a spring and a liquid are in series, the arrangement is such that when a thrust is transmitted through the spring to the liquid, the liquid yields by flowing into another vessel the volume of which varies in an inverse manner, after which the parts gradually assume their previous relative positions. In the construction shown in Fig. 1, the body d is supported by a piston a on liquid contained in the cylinder b which is in one with the lower cylinder f, the two cylinders being separated by a partition c. The axle k supports the vehicle through the piston h acting on the lower end of the helical spring m. The upper cylinder b and the lower cylinder f are connected by pipes n. When the axle rises suddenly the spring m is compressed and raises the partition c together with the cylinders b, f so that liquid flows from the upper to the lower cylinder through the pipes n, and the piston a and body thus follow the upward movement of the axle very slowly. In a modification the lower cylinder is of larger diameter than the upper and the arrangement of the spring is such that the connecting pipes may be dispensed with. In a further modification a laminated spring is employed, as shown in Fig. 3. Two cylinders b are connected to the ends of the spring and the single cylinder f of larger diameter is rigidly connected to the end cylinders by pipes n while its piston h moves with the axle.
