Patent GB-926099-A (GB)
Abstract: 926,099. Dynamo-electric machines with semi - conductor devices for commutation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 23, 1960 [Oct. 6, 1959], No. 33860/59. Addition to 902,352. Class 38 (2). In a dynamo-electric machine which has controllable semi-conductor switching devices instead of a commutator as disclosed in the parent Specification, the current in an armature conductor path such as p3 is reversed by the simultaneous operation of a pair of devices controlling that path during the period when that path is between poles and the arrangement is such that the path is not connected directly across the armature terminals during this period. In one embodiment, Fig. 3, the three paths shown, p1, p2, p3, are each supplied by a bridge connection of devices such as 31, 31<SP>1</SP>, 32, 32<SP>1</SP> and the three paths are in series between D.C. supply terminals TT so that two other paths are in series with the path being switched. In a second arrangement, Fig. 5, two chains of devices 51, 52, 53, 54, 51<SP>1</SP>, 52<SP>1</SP>, 53<SP>1</SP>, 541 are disposed between the terminals and the paths p1, p2 p3 are connected between their junctions. The switching of the devices is such that a path passing between poles is not in circuit though the other two paths are in series between the terminals. For example when path p2 is passing between the poles devices 51, 52<SP>1</SP>, 53<SP>1</SP> and 54 are " on " and the others " off " so that p2 is disconnected and p1 and p2 are in series. As p2 comes under the next pole devices 52 and 52<SP>1</SP> reverse simultaneously so that path p1 is out of circuit and current flows through S1, S2, p2, 53<SP>1</SP>, p3, 54. In a further arrangement, Fig. 6, a cyclical arrangement of paths p1, p2, p3 has pairs of devices 61, 61<SP>1</SP>, 62, 62<SP>1</SP>, 63, 63<SP>1</SP> connected to each junction, one of each pair being connected to either terminal. Switching is such that only one positive side switch (say 61) and only one different negative side switch (say 62<SP>1</SP>) are " on " at any time when current flows directly through one path (p1) and through the other two in series. The switching of devices 61 and 63, puts p2 alone across the terminals and p3 and p1 in series and changes the direction of current through p3, this switching taking place whilst p3 is between the poles. A cyclical switching procedure takes place. In all cases the switching occurs at two devices simultaneously, these acting as a bistable pair, which may be interconnected by a commutating capacitor. The devices may be silicon-controlled rectifiers or transistors. Figs. 7 and 8 (not shown) give detailed circuits for the arrangements of Figs. 6 and 4.

Title: Motion compensated video signal processing; detecting "ridge" motion
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: G06T7/20
Filed: 1993-04-08
Abstract: A correlation surface is formed and stored 300 by comparing search blocks in a first image with a search area, comprising a plurality of search blocks in a second image, and a motion vector determined on the basis of the position of maximum correlation. Movement of a "long" (longer than the dimension of the search block) object along its length causes a ridge of similar maxima to occur on the correlation surface in the direction of motion; these are detected 360, 400 and counted 490 to generate a ridge flag 495 if a predetermined number occur. If ridge motion is detected a true motion vector may be determined from an average of the most widely spaced maximum correlation positions. The correlation surface may be formed by subtracting luminance values in the two images to produce a correlation surface in which a minimum represents a point of maximum correlation. <IMAGE>

Patent GB-936016-A (GB)
Abstract: 936,016. Train control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. (Philips' Gloeilampenfabrieken N.V.). Aug. 14, 1961, No. 29261/61. Class 105. A signalling system for controlling the speed at which a train passes a point on a track or for bringing the train to a halt at that point comprises an insulated section of track Vn, a main station En and sub-stations RO-n, R30-n, R90-n, each capable of applying a " no-brake " signal to the track section, each sub-station being selectively controlled to apply the signal by a particular frequency signal transmitted from the main station via the track circuit and train equipment with coils positioned in front of the train for receiving the " no-brake " signal and applying the train brakes in the absence of a received signal. Each sub-station is associated with a required speed or a halt, e.g. R30-n is associated with 30km/n and RO-n with a halt, and is positioned in advance of the point on the track, e.g. signal Sn, such that if the train brakes are applied at the sub-station its  speed is reduced to the required speed or it is brought to a halt at the signal. Assuming the train speed has to be reduced to 30km/n at the signal, station En selectively applies a signal to the track circuit at a frequency characteristic of sub-station R30-n, entry of the train into the section allows current to flow in the circuit at that frequency which energizes a switching circuit at the sub-station via which the " nobrake " signal is applied to the track. Under the influence of this signal the train proceeds until it reaches the sub-station where its axles short out both the selective signal to the substation and the " no-brake " signal applied from the sub-station. Train braking automatically  ensues and the train speed is reduced to 30km/n at the signal. Where no speed restriction is required the " no-brake " signal is applied to the circuit from the main station. Two different frequency " no-brake " signals may be used alternately from section to section to obviate the danger of signal leakage between sections, in which case a train circuit co-operates with track apparatus TN at the entry to each section to switch the train receive circuit to the correct " no-brake " frequency.

Title: Dough manipulation apparatus
Inventor: WRAY MARTYN THOMAS
IPC: A21C3/02
Filed: 1995-06-09
Abstract: With reference to Figure 2, dough manipulation apparatus 100 is shown thereby, in combination with a biscuit cutting machine 101. The apparatus 100 is operable to form and then manipulate dough sheets 103 before output of the sheets to the biscuit cutting machine 101, and comprises a sheet forming unit 104, a sheet laminating unit 105 and means 106 for controlled bypass of the sheet laminating unit 105, whereby output of sheets 103 produced by the sheeter 104 can be passed, by downwardly-inclined conveyor 107, direct to the biscuit cutting machine 101, without lamination. With additional reference to Figures 3 and 4, the bypass means 106 comprise a conveyor 115, a further conveyor 134 disposed beneath the lower roll 114, and a diverter device 135. The conveyor 115 is movable substantially horizontally, as indicated by double-headed arrow 136, from a position relatively close to the bottom roll 114 (Figure 3) to another position (Figure 4), relatively remote therefrom. This movement of the conveyor 115 is achieved by actuators 137 (Figure 4 only). The actuators 137 provide means for selectively bringing the bypass means 106 into, and out of, operation. With reference to Figure 4, to bring the laminator 105 (Figure 2) into operation, the actuators 137 are operated so as to pull the conveyor 115 away from the lower roll 114 of the sheeter 104. Dough sheet 103 produced by the sheeter 104 can now pass downwardly on to the conveyor 134, and then over the rollers 142 of the diverter device 135 and beneath the retracted conveyor 115. The sheet 103 then falls over an inclined bar 140 and on to conveyor 120 (Figure 2) so that it is transported to gauge rolls 121-124. Thereafter the sheet 130 is cut into lengths, the lengths superimposed on each other to form a laminate, and the laminate supplied to the biscuit cutting machine 101 by the conveyors 126-128.   The biscuit cutting machine 101 and sheet forming unit 104 of the apparatus are in alignment, as shown. The whole arrangement results in a compact production plant 108.
