Abstract: 744,367. Automatic current control systems. REYROLLE & CO., Ltd., A. Nov. 26, 1953 [Nov. 26, 1952], No. 29964/52. Class 38 (4). In a system for automatically maintaining equal the relative currents of three Schrage motors by means of three reversible pilot motors each actuating the main motor brushes or an associated induction regulator, currents corresponding respectively to the load currents are supplied to the primary windings of three balancing transformers each having a secondary winding controlling its pilot motor in accordance with the vector difference between pairs of load currents. The transformers are saturable to protect the pilot motors. The motors (not shown) are supplied at A, B and C, Fig. 1. Current transformers 10A, 10B, 10C energize the primary windings 14A, 13B; 14B, 13C; 14C, 13A respectively of balancing transformers 12A, 12B, 12C, so that their secondary windings 15A, 15B, 15C have outputs proportional to the vector differences between the three motor currents taken in pairs. These secondaries each energize one phase winding of each of the pilot motors 11A, 11B, 11C which operate as reversible two phase motors to adjust the brushes of the Schrage motors. In a modification, Fig. 2 (not shown), each pilot motor is supplied through an interrupter so as to prevent it from continuing to run as a single phase motor when the control winding is not energized. In a further modification, Fig. 4 (not shown) the pilot motors are braked by passing D.C. through their reference windings whilst the A.C. is interrupted. In a further modification, Fig. 3 (not shown) all three windings of each pilot motor may be connected to a three phase supply through reversing contactors so that the motors can be manually controlled. In - a further modification, Fig. 5, the interruption of the A.C. supply 1, 2, 3 to each pilot motor, only one of which is shown, e.g. 11, and the intermittent connection to the D.C. braking source 42, is effected respectively by contacts 36, 37 and 39, 40, actuated by a solenoid 35 in series with the control winding 1. The motor thus runs when the error signal in winding 15 exceeds a given limit, and is braked below the limit. Contacts 44, 45, 46, 47, 48, 49, 50 enable the selection of " manual raise," automatic " and " manual lower to be made.

Filed: 1952-12-01
Abstract: 709,257. Television. HAZELTINE CORPORATION. Dec. 1, 1952 [Dec. 18, 1951No. 30431/52. Class 40 (3) In a compatible dotsequential colour television receiver a carrierwave signal modulated by the colour components and having a frequency y substantially higher than the highest frequency of the composite video signal is derived and added to the latter signal and the combined signals are then "sampled" at a rate corresponding to the frequency of the derived carrier vane. This arrangement reduces the visibility of the spurious dot patterns which occur in grey and white areas due to the normal (approx. 3-5 mc/s) colour sub-carrier wave. In one embodiment, Fig. 1, a filter 35 selects the colour sub-carrier, which occurs at a frequency of about 22.5 mc/s, from the I.F. amplifier 14 of a convential receiver and supplies it to an adding circuit 17 in which it is combined with the normal modulation signal comprising the 0-4 mc/s brightness components and the 3.5 mc/s colour-sub-carrier. The combined signals are then supplied to the modulating electrodes of a single gun tri-colour picture reproducing tube 18 the single beam of which, (in addition to the usual rectilinear scanning produced by generators 26, 27 and scanning coils 21, 22), is given a rotatory motion (to select the colour) by means of coils 19, 20 fed from the phase quadrature 37 and controlled by a 22.5 mc/s signal from oscillator 36, which also supplies, via multiplier 38, the usual gating signal to the cathode of tube 18. The phase and frequency of oscillator 36 is controlled by a device 39 which supplies a control signal in accordance with variations of oscillator frequency from the 22.5 mc/s frequency derived from I.F. amplifier 14, Fig. 1a (not shown). An embodiment which employs a tri-colour picture reproducing tube having three separate electron guns is described with reference to Fig. 2 (not shown), Specification 689,821 is referred to.

Filed: 1968-06-26
Abstract: 1,216,573. Film cassettes. EASTMAN KODAK CO. June 26, 1968 [June 29, 1967], No.30451/68. Heading G2A. A film container is provided with tactile coding means indicative of the length of a film strip therein, and the camera which receives it has means which detects this coding means and sets the exposure counter accordingly, e.g. to an initial setting of 20 or 36 exposures. As shown in Fig.1, a cassette 11 has a coding projection 19 thereon. The dial Fig.4, (not shown) of the exposure counter has two concentric rows of exposure numbers, starting at 36 and 20 respectively, which are visible through a window 84 in the camera cover. A lever 86, which pivots on a bushing 29 supporting the rewinding spindle 28 which passes axially through the cassette 11, has an arm 89 which extends across window 84, and can obscure either the inner or outer row of exposure numbers. The lever is biased by a light spring 88 attached to a finger 92 thereof, and if there is no coding projection on the cassette, it takes up the position of Fig.6, leaving visible the outer row of numbers corresponding to 36 exposures, and sets at the initial number 36. If a cassette carrying the coding projection 19 is inserted into the camera, then as it is properly located therein and the cover door closed, the finger 92 is engaged and pushed by projection 19 so that lever 86 takes up the position of Fig.5, so leaving visible the inner row of numbers corresponding to 20 exposures. As the film is wound on frame by frame, the number visible in window 84 then reduces, one by one, in the usual way. The dial 58 is attached to the top end of a shaft 59 supported by internal wall members 31, 27, the shaft carrying a ratchet wheel 61 at its lower end. The ratchet wheel, and hence the dial, is turned step by step by the toothed end 69 of a pawl arm 66 pivoted at its other end to a cam follower 63. This is actuated in turn by a cam 49 on the driving member 34 which turns the core 33 of the film take-up spool, and is itself driven by the winding lever 37. The pawl arm is spring-biased out of engagement with ratchet 61 when the camera cover door is opened, so allowing the dial to be returned to its initial position by a restoring spring. In the modification of Figs.7-12 (not shown) the cassette has three coding projections, corresponding to three different lengths of film. In this case the counter device is set by a pinion and gear segment arrangement. In the further modification of Figs.13-19 (not shown) the film-advancing mechanism is disabled automatically after the last exposure has been made (by disengaging the ratchet parts 47, 48 of Fig.1), to allow of re-winding.

In operation, one mould 14, Fig. 6, closes on extrudate 10 from the oven and, after moving a distance "L" from the open clamps 12, at the position X (Fig. 5, not shown), the clamps 12 move at the same speed as the mould, i.e. faster than delivery of extrudate from the oven and after a further distance D (almost 1¢L) clamps 12 are closed, Fig. 6 and moved back to position X (Fig. 7, not shown), while the mould moves on further to position Z so that the length of extrudate between the mould and clamps is stretched from a length L to 2¢L and oriented, and the stretched length between the oven and the clamps merely recovers elastically. Meanwhile, the other mould 16 is open and is returned to the starting position (Fig. 7, not shown) and an article 18 is blow-moulded in the mould 14 and, after opening mould 14, is passed to a finishing station. In an alternative method of operation, (Fig. 8, not shown), the open clamps 12 and closed mould 14 move together a distance D, where clamps 12 stop and the mould then continues a distance L to position Y. The clamps 12 then close and move back to their initial position X while mould 14 moves on to Z.
