Patent GB-2140185-A (GB)
Title: Preventing collisions between automated vehicles
Inventor: BURGER REINHARD
IPC: B61L27/04
Filed: 1983-12-07
Abstract: A method and a vehicle system in which a collision between vehicles travelling one behind the other is avoided. Individual vehicles are interrogated and directed to send out position signals from which the distance between vehicles which directly follow each other in the direction of travel can be determined. From the information received stop or slowing-down signals are derived which prevent a collision between the vehicles. The system comprises, on each vehicle (10), a vehicle control unit (12) and a transceiver (14) which receives signals from an interrogator in a section control unit (AS1) via contact line (L) and contact (16a). The vehicle carries a sensor (S1) which detects passage across boundaries between sections of the contact line and a second sensor (S2) which measures vehicle position along a scale. <IMAGE>

Title: Apparatus for performing a plurality of processing steps on workpieces and conveying the workpieces between processing stations
Inventor: STRANGE RAYMOND ARTHUR
IPC: B65G49/04
Filed: 1984-10-25
Abstract: Apparatus for performing a plurality of processing steps on a plurality of workpieces, such as surface penetrant nondestructive testing processes and cleaning processes, comprises first and second carriers for workpieces, first and second processing means (12, 14) for performing distinct processing steps on the workpieces, and transporting means (26) for transporting a carrier to and from the various processing means and adapted to release the carrier therefrom at a selected one of these processing means.

Title: A power supply circuit for a device for monitoring carbon monoxide content
Inventor: WEILER DR HORST
IPC: G01N27/49
Filed: 1985-09-25
Abstract: A circuit layout for the supply of power to an electrochemical device for the continual monitoring of the carbon monoxide content of underground air currents which device creates an output current proportional to the CO content of the air current. The sensor is driven by a potentiostat circuit with a test amplifier for the output current and an adjustable amplifier feeding a recorder output. These devices are powered from an intrinsically safe source (shown as an accumulator with limiting resistors R1, R2 and fuse S1) via a constant voltage regulator with an operations amplifier coupled to its output and an indicator as to whether sufficient operational voltage is being supplied. The power supply maintains the sensor in operating condition removing the need for a 14 hour activation phase. <IMAGE>

Title: Moulding tyres
Inventor: HOLROYD ERIC
IPC: B29D30/06
Filed: 1986-01-15
Abstract: A method of manufacture of a tyre comprising premoulding and assembling tyre components in a shaped mould 50,60,61 having no strength in itself. The mould is externally supported in a housing 55,65,66 during the moulding operation and assembly and consolidation of components. The mould is then released from the housing and the unvulcanised tyre, in the mould, located in a pressure vessel and subject to all round gaseous pressure, and the tyre is vulcanised by the application of heat in the pressure vessel. There is also described a shaped mould (50) having sufficient strength to support an unvulcanised tyre but having insufficient rigidity in itself to withstand moulding pressures. A housing (55) (65) (66) is provided to support the mould during the moulding operation. <IMAGE>
Patent GB-2186374-A (GB)
Title: Signal compensation circuit
Inventor: TRETT JOHN
IPC: H03K17/16
Filed: 1986-02-06
Abstract: A detection system for a sliding lift or elevator door comprises at least two sensors (24,26) for monitoring the door opening. The sensors (24,26) are arranged to detect the presence of moving irregular shape (e.g. the human form) in the doorway to reverse the opening action of the door or, if already open, to prevent the door from closing. A signal compensation circuit is provided to process the output signals from the sensors in a sense to maintain the outputs equal under steady state conditions. This is achieved by using the output of a first sensor (26) as a quasi reference signal. A comparator (113) compares the output of a second sensor (24) with a quasi reference signal and through a feedback loop (139) modifies the output of the said second sensor (24). The feedback loop (139) contains a delay circuit (117,122,123,126) which is switchable between a long and short delay. For slow changes in the output of the second sensor (24) the long delay is effective but for fast changes the delay circuit (117,122,123,126) is switched to provide a short delay. The compensation circuit is effectively desensitised against errors due to drift and other slow varying influences.

Title: Double polarization flat antenna array
Inventor: CLERC FABRICE
IPC: H01Q21/00
Filed: 1987-03-31
Abstract: A flat antenna includes an array of radiating slots defined by an assembly of waveguides. The central section and the ends of the guides are provided with short-circuit pins (PCC, figs 7 and 8). In a geometric configuration close to that of the slots, there are radiating dipoles DR using microstrip technology, fed by connection areas between two dielectric substrates (figs 5A, 5B, 6A, 6B). The ground plane PM at the level of the lower dielectric substrate is cut out at right angles to the radiating slots and also at right angles to the passages for feeding the connection areas. The structure of the dipoles can be made entirely decoupled from the structure of the slots, enabling mutually uncoupled operation in two different polarizations. The feed lengths to the dipoles may be made equal (figs 6B, 7). In a four quadrant structure (figs 7 and 8), the dipoles may be provided throughout the circular area.
