[Also in Division G1] An arrangement for monitoring the position or vigilance of an operator positioned at a control station, e.g. a train driver, comprises an RF transmitter and a receiver arranged so that the energy level received is dependent upon the position of the operator. The operator may provide the coupling between a transmitter, e.g. a transmitter oscillator built into, for example, his seat and a receiver antennµ let into a control handle or he may serve to load a transmitter the output of which is measured as function of his position. The receiver may be caused to give the operator a preliminary warning and/or may cause the operation of a safety device such as the brakes. Further receivers may be used to monitor more effectively the operator's position and may be used in conjunction with a timing circuit to indicate whether or not the operator has moved in a predetermined time. The additional receiver antennµ may be housed in the seat or in various control handles and each change in a receiver circuit is used to produce a reset pulse in the timing circuit which may be electronic and include a resistor capacitor network. The preliminary warning device may comprise a loud-speaker to which an audio oscillator is connected intermittently by a flip-flop device, and/or a flashing warning light. The control console may be provided with a reset button which the operator may use in the event of receiving a warning, and this arrangement may be used in conjunction with apparatus for measuring his time of response to detect any deterioration in his performance during a period of study.

Title: Improvements relating to the propulsion of vehicles
IPC: H02N11/00
Filed: 1957-12-17
Abstract: 830,816. Discharge apparatus. DE SAN, M. G. L. M. J. Dec. 17, 1957 [Dec. 17, 1956], No. 39181/57. Class 39(1). [Also in Groups XXXIII and XXXV] An aircraft or floating or submerged vessel is propelled by the interaction of a magnetic field and a stream of ionised air or other conducting fluid. The vehicle body 8 (shown in side view) is circular in plan view and has a circular conductor (not shown) within its outer edge. This conductor produces the flux 1 and is maintained in a supra-conductive condition by cooling by the evaporation of liquid helium. If the medium around the vehicle is not already conductive, the region in the direction of its motion 7 is ionised by a stream of ions 5 from emitters 6, which may be an electron source, e.g. a negatively-charged heated surface, a source of ultra-violet radiation, or radioactivity. An electric current passes laterally above and below the aircraft between electrodes 4 at its side edges. The ions produced at 6 ionise the forward air and so permit the passage of current laterally between the electrodes 4, this current interacting with the field 1 to produce motive force. The current between the electrodes can be produced by known means or radio-active bodies. The vehicle may be steered by controlling the ratio of current above and below the aircraft and by distorting the current flow by means of asymetrical fields.
