Title: Improvements in or relating to electric lighting systems
IPC: H05B39/06
Filed: 1919-04-22
Abstract: 145,200. Wescott, D. E. April 22, 1919. Lighting systems; systems depending on the use of static transformers.-A switch in an arc lamp or constant current circuit is used to control the supply through a transformer to a number of auxiliary incandescent lamp circuits so that these circuits can be extinguished separately. The switch 8 is in the main are-lamp circuit, which also contains two electro-magnets 9, 14 for the primary and secondary of the transformer. The secondary is divided, the separate lamp circuits being connected to the parts. With both switches 9, 14 closed all the circuits are under supply; with the switch 9 only closed, only a part of the auxiliary lamp circuits are energized. To enable the switch 9 to be closed, when the switch 14 is open, the latter has a rod 25 suspended from the movable contact member 16; this rod carries a cross-pin 27 which enters either deep or shallow notches 41 in a ring 31. When in the shallow notch the switch cannot close, although the electro-magnet is energized by the switch 8. To move the cross-pin round from a deep to a shallow notch and vice versa the switch 8 is opened momentarily. The pin in dropping falls on inclined teeth 42 in a second ring 30 and moves round; when the switch 8 is closed again the contact in rising brings the cross-pin into the next notch and so holds the switch open or allows it to close according as to whether it was previously closed or open. When the switch 8 is left open all the lamps are extinguished.

Title: Digitiser
IPC: G05D3/20
Filed: 1966-03-08
Abstract: 1,149,249. Selective signalling. HOLLANDSE SIGNAALAPPARATEN N.V. 8 March, 1966 [12 March, 1965], No. 10200/66. Heading G4H. An arrangement for digitizing two denominationally related coarse and fine intervals by counting clock-pulses in coarse and fine counters having one or more overlapping stages, is characterized in that the coarse counter is initially set to a negative value, whereby at the end of a digitizing period when the overlapping counts are compared, the coarse counter can be corrected by being stepped in one direction only. Specification 1,149,250 is similar but instead of giving a negative bias to the coarse counter, a reversible counter is used. The arrangement is described as applied to a displacement encoding system using gear-coupled synchros as described in Specification 1,136,247, which is referred to. Pulses from an oscillator (101, Fig. 1, not shown) pass through a divider (102) to a three-stage ring counter (S, T, U) producing square waves for application to the primary windings of transformers (111, 115 and 116) giving differentially timed pulses representing respectively the coarse, fine and reference positions. The secondary windings of the fine and coarse transformers are coupled by gearing. The outputs from the three secondary windings are squared and applied to circuitry (Fig. 2, not shown) controlling the passage of clock pulses, through a divider (106) to coarse and fine counters (GT, FT, Fig. 3, not shown). Because of back-lash in the gearing the coarse counter may be inaccurate in the least significant digit or digits. In one form (Fig. 3) the counters are binary scale and the error is assumed to reach a possible magnitude of seven. The last three stages of the coarse counter overlap with the highest three stages of the fine counter and the contents of these stages are compared and if inequality is found a trigger (W) is set (signal on lead 316) opening a gate (305) to allow more pulses to enter the coarse counter. To ensure that the correction will always be in the same direction, the coarse counter is reset between operations to a value of - 4 and the correction pulses bring the value in the last three stages into agreement. In the divisional application the coarse counter is designed to be corrected in either direction by providing a carry stage between the third (value 4) and the fourth stage (value 8) so that if the correction required is such that it would cause a carry signal to the fourth stage, this carry signal is provided in an appropriate direction. The counters may count in decimal scale, the overlap then being confined to a single digit. The transformers may be replaced by rotary scanning arms each deriving a differentially timed pulse from members connected to the input shafts. The circuit arrangements are described in detail.

Abstract: 932,732. Tufting machines. SINGERCOBBLE Ltd. May 22, 1962 [March 21, 1961], No. 10225/61. Class 112. [Also in Group XXIV] In a tufting machine two spaced work-feed rollers are driven through uni-directional clutch couplings by members connected to a common eccentric-operated or cam-operated member, means being provided both for adjusting the effective stroke of each coupling separately and also for adjusting the effective strokes simultaneously. As shown, spiked feed rollers 6, 7 for the base fabric a in a tufting machine have each rigid therewith a ratchet wheel 8. Concentric with each of the latter is a fixed segment 9, and pivoted about the axis of each roller is an arm 10 carrying a pivoted pawl 15. Pivoted to the arms 10 are the ends of respective telescopic rods 11, 12, the other ends of which are pivoted to one another and are also pivoted adjustably to a pitman 5 actuated by an eccentric 3 on the main shaft 2 of the machine. By shifting the pivotal connection 13 of the rods to the pitman along the axis of the latter, the effective strokes of the pawls 15 are simultaneously adjusted. Individual adjustment of said strokes may be effected by varying the length of the associated rod 11, 12, whereby the pawl 15 rides immobilized for a shorter or longer portion of its stroke on the segment 9. A reverse pawl 16 is provided. In a modification, one arm of a threearmed lever is adjustably connected to the pitman, and the other arms are adjustably connetted by respective links to arms pivoted about the axes of the rollers 6, 7 and coupled to the latter by sprag clutches.

Title: Improvements relating to control systems for electrically operated reversible rolling millsand the like
IPC: B21B37/54
Filed: 1946-04-03
Abstract: 618,875. Control of two D.C. motors. GURNEY, N. R. D., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 3, 1946, No. 10301. [Class 38 (iii)] A strip winding and unwinding system comprises a reversible electric motor M for driving the mill rolls or like which act on the strip, and dynamo-electric machines L and R which are coupled to winding reels disposed on opposite sides of the rolls and each operating as a wind-on motor or a wind-off braking generator according to the direction of the pass. A generator G supplies the motor M and that machine, L or R, acting as the wind-on motor. In order to provide a wider range of speed variation for the wind-off reel than for the wind-on reel, a negative booster machine N for the wind-off generator is provided. Constant strip-tension is maintained during running conditions by regulation of the power input to the wind-on motor and of the output of the wind-on generator in response to the voltage-drop across a resistor in the armature circuit of the regulated machine, the presence of such resistor effecting a tendency for the main mill motor to accelerate at a greater rate than the wind-on motor from rest. A positive booster C is provided for the wind-on motor so as to overcome this difficulty. In the intervals between reversals of the direction of pass the machines L and R are disconnected from the generator G and, by closure of contactors b, c, d, and e, are connected in a closed bridge circuit with the machines C and N and regulating resistors RG and RM, so maintaining a stalled tension of the strip at standstill. Closure. of contactors f and i will then connect the machine R, in series with the machine C and resistor RG, across the armature of the generator G, for operation of the machine R as a wind-on motor, the machine L, which acts as braking generator, being connected across the generator G in series with the resistor RM and the machine N. The reverse direction of pass is provided by reversal of the motor M, the opening of contactors f and i, and the closure of contactors g and h, so that the circuit connections and the functions of the machines L and R are interchanged. The connection of the machines affording stalled tension of the strip is thereby uninterrupted during the reversal of direction of the pass. For inching operation, the mill motor may be connected to the main generator and the reel machines connected'in local circuits with the machines C and N respectively. Alternatively, either reel machine may be inched in either direction together with the mill, the other reel machine being connected in a local circuit with the appropriate booster C or N.
