Filed: 1972-04-10
Abstract: 1390373 Transport system MAATSCHAPPIJ VOOR INDUSTRIELE RESEARCH EN ONTWIKKELING NV 10 April 1972 [15 April 1971] 16370/72 Heading B7L Transportation apparatus particularly for the indoor transport of articles comprises a carriage 6 and a track 5 formed by two parallel cylindrical elongated elements 53, 53<SP>1</SP> spaced apart by clips 10 (omitted for clarity on some diagrammatic Figs.) extending between the elements, the inner surface parts of the elements 53, 53<SP>1</SP> which face each other constituting guide paths for travelling wheels 20, 21 of the carriage 6. The same set of travelling wheels is utilized in both horizontal and vertical parts of the track, the rotational axes of the wheels lying perpendicular to the plane in which the track elements lie. Each track element may comprise several part elements adjoining each other in series and connected together by the mutual coupling of adjoining clips 10 which are fitted adjacent the ends of adjoining part elements. An element 53 has a row of protruding pins 54 directed towards the other element 53<SP>1</SP> in a curved or vertical part of the track, the pins being of four-sided frusto-pyramidal shape and of a length which increases and decreases at the beginning and end of the row respectively. A driving wheel such as 68<SP>1</SP>, Fig. 11, or that shown in Fig: 8b, has circumferential apertures 22 to engage the pins 54 and thus drive the carriage 6. The driving wheel 68<SP>1</SP> is driven via reduction gearing 67<SP>1</SP> by a motor 66<SP>1</SP> supplied with electrical power by an accumulator carried on the carriage 6. The wheel 681 may also have friction surfaces on either side of apertures 22 which engage the track elements to drive the carriage in some, e.g. horizontal, sections of track but are spaced therefrom where pins 54 are supplied, as shown in Fig. 8b by the provision of grooves 53a, 53b in the track elements. The travelling wheels are mounted in pairs, e.g. the two wheels 20 which may rotate about an axis perpendicular to both the longitudinal track direction and their axles, to allow easy negotiation of bends, e.g. 27, 30, 32 in Fig. 1. The driving wheel, e.g. 68<SP>1</SP>, Fig. 11, is resiliently biased into engagement to element 53 in opposition to a roller 175 which is resiliently biased towards element 531.

Abstract: 1,011,955. Automatic control of hydrofoil craft. UNITED AIRCRAFT CORPORATION. April 26, 1963 [Sept. 24, 1962], No. 16575/63. Heading G3R. In a system for automatically stabilizing the attitude of a hydrofoil craft, signals dependent on heave and roll control only the control surfaces of port and starboard main support foils which pierce the water surface, while signals dependent on pitch control only the control surfaces of additional support foils which are completely submerged. A hydrofoil craft, the frontal view of which is shown in Fig. 2, has double dihedral forward foils 10,12 which pierce the water surface and have adjustable control surfaces 14, 16, and rear foils, completely submerged, having adjustable control surfaces 20, 22. In Fig. 3, heave of the craft is stabilized by electric signals from a vertical accelerometer 30 which are applied through a common pre-amplifier and lag integrating electronic circuit 32 to individual amplifiers 34, 36 controlling fluid-pressure servomotors 42, 44 actuating control surfaces 14, 16 on the forward foils in the same direction. Signal generators 46, 48 associated with the control surfaces apply positional feedback signals to amplifiers 34, 36. Pitching of the craft is stabilized by signals from a gyro vertical 50 which are applied through servo-system 52-58 actuating control surfaces 20, 22 on the rear foils. In more detailed modifications the rear foil control surfaces are controlled by signals from a pitch rate gyro and additional signals are injected to provide lagged manual trim and bias of the control surfaces before "take-off". Signals from a roll gyro are also applied to move the forward foil control surfaces in opposite directions to stabilize roll attitude, which may be trimmed by a manually operated signal generator. Signals are also applied from a generator associated with a manual controller to move the control surfaces on both the forward and rear foils in opposite directions for steering purposes. Signals dependent on rate of movement of the manual controller may also be added. There is provision for cutting out various signals, e.g. if the control surfaces are retracted, removing control surface bias smoothly after take-off, manually or automatically varying gain, e.g. with craft speed, and limiting the magnitudes of signals. Rotatable rear foils without auxiliary control, surfaces and use of roll rate signals are referred to.

Title: Improvements in train control
IPC: B60L15/00
Filed: 1925-06-29
Abstract: 237,578. General Railway Signal Co., (Assignees of Bushnell, C. S.). July 25,1924, [Convention date]. Track apparatus for stopping trains. - An apparatus for applying brakes on a train comprises a speed governor and a mechanism operated in accordance with the distance travelled by the vehicle, the arrangement being such that if the means for driving the speed governor becomes inactive, the brakes are applied. The governor G, driven from the train wheels through a shaft 5, controls a rocking shaft 13 carrying a contactclosing cam 19 and an arm 25. A gear 6 also driven from the shaft 5 is normally disengaged from the distance shaft 14 bv an electromagnetically controlled gear lever 15, and serves, when the magnet CS is de-energized, as at a caution signal, to drive the shaft 14 and the permissive speed cam 21 in accordance with the distance travelled by the train. A lever 24, pivoted on the crank 25 and abutting on the cam 21, controls the contact-making cam 26 so as to open the circuit to the brake valve magnet, EPV, if the speed is higher than the permitted speed at any distance beyond the point where the magnet CS is de-energized. A contact cam 20 on the distance shaft closes a circuit to the relay CR so long as the shaft 14 is out of the normal position, thereby keeping the relay energized although the main relay MR, controlled from the track, is de-energized. If the transmission 5 breaks down, the governor stops and the contacts 22 are opened but the consequent de-energization of the magnet CS does not cause rotation of the shaft 14, hence contacts 23 are not closed and the relay CR is controlled solely by the relay MR and the brakes are applied independent of the speed of the train.

Abstract: 895,983. Automatic - exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 5, 1960 [May 15, 1959], No. 16739/59. Class 40 (4). A cross-point switching arrangement comprises a co-ordinate matrix of semi-conductors, one of which is rendered operative by row and colunm markings applied to two electrodes thereof to energize an associated relay. In Fig. 1, transistors such as TR are employed, positive " row " pulses being applied to the emitter by way of relay coils RC and negative "column" pulses to the base. When the transistor conducts, a high value capacitor C1 is charged from a floating power supply, which may consist of a second high value capacitor C2 fed with rectified A.C., and provides current for the operation of relay RC, as long as the pulse repetition rate is sufficiently high. The relay is preferably of the dry reed type. Instead of transistors, crystal diodes may be used and these may be associated with transistors acting as amplifiers. In a 100-line exchange the subscribers' lines would be arranged in columns divided into two halves for the calling and called sides of a connection, the rows in the two halves being connected in pairs to form transmission bridges. The marking pulses may be obtained from single-shot multi-vibrators, Figs. 3, 4 (not shown), under the control for instance, of a magnetic drum register.
