Title: Improvements in or relating to regenerative repeaters for telegraph signals
IPC: H04L25/04
Filed: 1935-06-28
Abstract: 440,092. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Western Electric Co., Inc. ; 195, Broadway, New York, U.S.A.) June 28, 1935, No. 18567. [Class 40 (iii)] A repeater for signals comprising start, character and stop impulses consists of a receiver 200 and a retransmitter 240 which lags in phase by a predetermined amount behind the receiver, means for correcting errors in the phase-lag being provided. The first impulse of each group received by magnet 9 is a start impulse occupying one time unit. It trips the catch 201 and releases cam shaft 82 for one revolution. The next five impulses act through sword-and-T mechanism 13, 26, to set five slides 221 controlling contacts 222. The final or stop impulse as received from the line occupies one time unit, and operates the slide 221<1> so that the corresponding contact remains closed except when a prolonged stop or open-circuit signal is received from the line LW. The shaft 82 normally stops for half a unit before the next signal arrives, but the sending-on brush 242 does not normally stop. This brush sends on impulses determined by the contacts 222. The start signal, comprising a no-current impulse, is sent on automatically, the segments 247, 248 being allocated not for a start signal but for regulating the lag between the receiving shaft 82 and the sending-on brush 242. If the brush runs too fast it is stopped by the catch 243a at the end of each revolution until released by the action of magnet 264, which is energized under the control of receiver cam 262. The magnet 264 holds on until it is de-energized by brush 242 through segments 247, 248, the start magnet 243 being energized at the same time. If on the other hand the brush 242 runs too slow the speed of the motor 261 is increased. To this end the normal resistance 269 which co-operates with the governor 268 to determine the speed of the motor 261 is shunted by a second resistance 270 if cam 262 closes its contact when relay 264 is holding on, and the shunt circuit is broken when relay 264 releases under control of the brush 241. Alternatively, Fig. 1a (not shown), the shunt circuit may be controlled simply by the relay 264, the cam 262 being dispensed with. In either case the duration of the shunting action depends on the amount of lag between receiving cam shaft and sending-on brush. In a modification, Fig. 2 (not shown), the sending-on brush normally stops at the end of each revolution and the start impulse is applied to magnet 243 by a relay controlled by relay 264 through a delay network giving a delay equal to the desired minimum lag. If the motor runs too slow, the action of the relay is accelerated by priming current applied by relay 267.

Title: Improvements relating to resilient rollers
Inventor: CLEMENTS HENRY
IPC: D01B3/10
Filed: 1952-07-24
Abstract: 714,891. Rollers. ANDRE RUBBER CO., Ltd. Feb. 13, 1953 [July 24, 1952], No. 18748/52. Class 42 (2) Relates to resilient rollers for wool-washing, of the kind comprising a plurality of smooth-bored annular units of elastomeric material assembled on a metal spindle so as to be individually rotatable but axially compressed between cheek-plates which are non-rotatable relative to the spindle, driving torque being transmitted to the units by friction due to axial compression; each annular unit A has, in one or each of its radial end surfaces, a circumferential rebate D surrounding and in communication with the bore of the unit, so that spaces are formed between adjacent units, each such space' containing lubricant which is expressed when the units are deformed on compression so as to lubricate the bearings of the bores of the units upon the spindle G. As shown, each unit consists of an annular element A of synthetic rubber bonded to a metal bush B which is a sliding fit on spindle G and the peripheral surface of which is domed. One face of each element A normal to the roller axis is provided with an axially projecting circumferential rib E while the other has a complementary groove F. End plates H are keyed to spindle G at L and are locked in place by split collets J. The roller is assembled by securing one end plate H, sliding a suitable number of units on to the spindle, after the introduction of a lubricant such as graphite into the rebates D, compressing the units axially by the other end plate. and securing that other end plate in position. During compression, some of the lubricant is forced along the inner spindlecontacting surfaces of bushes B, thereby facilitating restricted local creeping of the units on the spindle under localised pressure during usage. The spindle-contacting surfaces of bushes B may be spirally grooved to facilitate distribution of lubricant Instead of being bonded to bush B, element A may be keyed mechanically thereto or secured frictionally by being stretched on the bush; alternatively, the bushes may be omitted, each unit consisting wholly of rubber or synthetic rubber. Specification 697,814 is referred to.

Filed: 1926-07-29
Abstract: 256,251. Lulofs, W., and Hanson, A. F. E. July 30, 1925, [Convention date]. Electricity, gas, and liquids, supplying by meter; mechanism for prepaying rent of meter; price-change mechanism.-In a prepayment meter having a fixed tariff device, during the separate fixed tariff periods, the driving mechanism, that is independent of the load, is automatically disconnected from the prepayment mechanism during a definite time adjustable for each fixed tariff period so that the fixed tariff can be varied in the separate fixed tariff periods. As shown applied to a prepayment electricity meter, the rotation of a knob 2 after the insertion of coins closes a switch 4 and rotates a sun-wheel 5 to set forward the planet-wheel 6 of an epicyclicmechanism controlling the switch. The wheel 6 is returned by the sun-wheel 9 which is driven through gearing 10 by the planet-wheel 11 of an .epicyclic mechanism 11, 12, 13. The wheels 12, 13 rotate in opposite directions and are driven respectively from a shaft 23 of the consumption meter and from a shaft 24 of an operating mechanism working at constant speed independently of the load, for example, a clock, Ferraris motor, or a synchronized motor. A worm 15 engaging a worm-wheel 16 is also driven from the shaft 24. The wheel 16 carries a rental tariff wheel 17 which makes one revolution per .annum and is provided with a peripheral recess for each month, the width of each recess depending on the rental fee to be paid for that month. A lever 19 controlled by a spring 20 has a, projection 18 for engaging the recesses in turn. When the projection is in a recess the lever 19 raises a rod 21 thereby disengaging a gear wheel 22 of the train between the shaft 24 and the sunwheel 13, and allowing the planet-wheel to be returned by the action of the meter shaft 23 only. The sun-wheel 13 may be engaged and disengaged by a relay at a central station, the relay being automatically controlled by a tariff wheel of the type shown at 17. The consumption meter may have a price-change mechanism arranged so as to alter the gearing between the shaft 23 and the wheel 12 by means of a clock or a relay, or, in an electricity meter, resistance or choking coils may be provided for altering the constants of the meter to correspond with the price in force. The meter may also be one that is affected by the amount of the load, and is provided with several series of counting wheels to return the prepayment mechanism at different speeds.
