Patent GB-831830-A (GB)
Abstract: 831,830. Miner's safety lamps. SMITH, H. M. N., and JONES, H. Oct. 29, 1957 [June 14, 1957], No. 18780/57. Classes 75(3). and 75 (4) In a miner's flame safety lamp with an internal electric ignition device, the lamp top is closed at its lower end independently of the base by a closure located above the top of the base and the ignition device is arranged within the top so that when the top is detached from the base, the ignition device will remain enclosed in the lamp top. The ignition device may be a filament the energization of which by an electric battery is interrupted when the lamp top is detached from the base. As shown, a retaining ring 4 for holding the glass 3 against the lamp bonnet, is formed integral with a raised platform 5 which serves as a closure for the lower end of the lamp top independently of the top 6 of the base 7. The ignition filament is mounted between two antlers 19 on a carrier 20 slidable horizontally on the closure 5 and is spring biased towards the wick, one end of the filament being connected to the closure 5 and the other through a contact pin 34 on the carrier and a spring contact 33 insulated from the closure 5 and connected to an insulated contact ring 31 engaging a spring-pressed contact 28 to one pole of the battery 24, the other pole being connected through the top 6 to the closure 5 so that when the top and base of the lamp are detached from each other, the battery supply to the filament is completely interrupted. The carrier and filament are moved away from the wick when an outer wick tube 10 movable in apertures in the top 6 and closure 5, is raised by turning a control rod 16 in the suitable direction to raise or lower an actuating arm 13 which recieves the upper screw end of the rod 16 and is mounted on a guide tube 14 between the inner and outer wick tubes 9, 10 so that the outer wick tube 10 can be raised against action of a spring 12. As the tube 10 is moved upwards to reduce the flame, a cam 23 carried thereby engages and pushes the carrier 20 away from the wick and at the same time breaks contact between the spring contact 33 and the contact pin 34 thereby interrupting the feed of energizing current to the filament. In an alternative embodiment the filament carrier is pivoted on the closure and its angular position is controlled against spring bias away from the wick by a cam pivoted about a vertical axis and actuated by a rod extending to the exterior of the lamp and accommodated in a channel or passage in the closure, and one of the battery terminals engages directly with the contact ring 31. Reference has been directed by the Comptroller to Specification 804,288.

Title: Ignition system for an internal combustion engine
Inventor: BODIG BERND
IPC: F02P3/045
Filed: 1984-05-22
Abstract: The primary winding (5) carries current as soon as a first threshold value switch (20), controlled by an a.c. generator (27) connected to the input thereof, assumes its "on" state. Curve portion (Ue), preceding a peak value (Ud), of the alternating voltage signal (Ua) serves to switch on the threshold value switch (20), and the curve portion (Uf) following the peak value (Ud) serves to switch off the threshold value switch (20). Threshold value switch (31) operates at (Uc) and (Uc) and is connected with its input and that of switch 20 in parallel. In the event of the switch 7 not being changed over by switch 20 the electronic switch (7) is rendered non- conductive by the second threshold value switch (31) in conjunction with a timing circuit (47) comprising a control capacitor (41) which, in addition to its function in the timing circuit (47), is also used to shift the switching-on threshold (Ub) of the first threshold value switch (20), towards curve values at a greater distance from the peak value (Ud), after the internal combustion engine has exceeded a minimum speed ensuring that sufficient ignition energy is made available for an effective ignition spark even at high engine speeds. <IMAGE>

Title: Controlling the transmission of polarized light
Inventor: WOOD ROGER MICHAEL
IPC: G02F1/03
Filed: 1985-06-18
Abstract: An optical switching arrangement for controlling the transmission of linearly polarised incident light in dependence on its intensity is described. The arrangement includes a detector (7) responsive to the incident light to provide an output to a voltage supply (9). In response to the output the voltage supply applies a voltage across a control means e.g. a Pockel cell (1) such that the direction of polarization of the incident light is rotated by an amount dependent on the intensity of the incident light. A polariser (5) is arranged to transmit light from the Pockel cell (1) having only a predetermined direction of polarisation. Thus polariser 5 may prevent the transmission of polarized light when the intensity exceeds a predetermined level. A plurality of control means responsive to different wavelengths may be used. <IMAGE>
