Abstract: In order to screen the electronic modules arranged in a plastic housing against electrical and/or magnetic interference fields, the housing consists of at least one layer of a plastic-metal-flow-laminate (12). The screening of the electrical and/or magnetic interference fields is achieved with the aid of the metal flow embedded in the plastic. In this way, a plurality of layers of metal-flow-plastic-laminates and mineral-flow-plastic-laminates can, however, also be arranged next to one another. To dissipate the charges in the mineral flow, this can be connected to an earthing contact (Figure 3). <IMAGE>

Abstract: A bistable gas valve includes a housing (2) having a gas passage (4) therethrough leading to a gas beacon. A support member (10) is parallel to the housing (2), and an operating member (16) is pivotally mounted to pivot between a stable condition in which the passage entrance (6) is open, and a stable condition in which the entrance (6) is closed. Two coils (26) and (28), centre-tapped at the point (30), are wound round the housing (2) and support member (10) respectively. The region around the housing (2) and support member (10) is enclosed, and gas is fed to the enclosure from a pressurised gas source. A permanent magnet (22) biasses the operating member (16) into either one of the aforementioned stable conditions thereby either opening or closing the passage entrance (6). 
     If the passage entrance (6) is open then gas passes through the passage to the beacon lamp. To switch off the lamp an electric pulse is fed to the coils (26) and (28) to pivot the member (16) to its other stable condition thereby closing the passage entrance (6). 
     The pulses for causing the operating member (16) to pivot are produced by a pulse generator. If the beacon is used as a sun switch the pulse generator may be actuated by an output signal from a solar array. If the beacon is used as a flasher, then the pulse generator is actuated by operational characters admitted from a character store in response to an address counter.

Abstract: The ski brake consists of a plate (3) with two arms (1) which pivot about a spindle (4). The skier's boot is normally pressed over the plate so that the arms lie above the level of the ski under normal use. If for any reason the ski becomes detached from the boot a torsion spring swings the arms downwards into the snow to bring the ski to rest. In order to prevent the arms from projecting over the edges of the ski during normal use, a guide (8) with inclined surfaces is fitted to the plate. As the plate is swung towards the ski, the guide is pushed into a recess in the plate and its inclined surfaces press the arms inwards over the upper surface of the ski so that they lie within the ski edges.

Abstract: An arrangement for distributing wideband signals comprises a switching matrix (60) which is constructed from logic gates. Signals are applied at inputs (1 to 8) and fed to frequency modulators (21 to 28). The frequency modulators produce a hard limited output signal so that all the information content of the signals is contained in the transition times of the frequency modulated signal. The relative times of the positive (or negative) transitions are faithfully preserved when passing through the gates forming the switch matrix (60). The outputs of the switch matrix are demodulated by means of a pulse counting demodulator formed by a constant pulse width generator (31 to 38) and a low pass filter (41 to 48) and fed to a wideband amplifier (51 to 58) to enable an output signal having a predetermined level to be presented at the output terminal (11 to 18). 
     The use of a pulse counting demodulator is particularly useful when a fibre optic link (63) is used. The output of the pulse generator is fed to a driver (62) through the optical fibre (63) to a detector (64). The receiver equipment is limited to the optical detector (64), low pass filter (41) and amplifier (51). In addition the bandwidth of the optical fibre may be reduced as only the baseband component of the signal is required. 
     The arrangement may be used for the distribution of video signals.
