Title: Apparatus for use as anti dazzle and fog-penetrating device for use in conjunction with motor car headlamps
IPC: F21S8/10
Filed: 1929-01-16
Abstract: 328,017. Smith, F. H. Jan. M, 1929. Lantern screens. - For anti-dazzle and fog-penetrat. ing purposes a part or the whole of the light projected by a vehicle lamp is adapted to traverse one or more screens each of which contains an electrolytic solution capable of assuming or deepening in an amber, orange, or other colour when an electric current is passed through it and of re-assuming its original clear or slightly tinted state when the currrent is switched off. The screens may contain a solution of potassium iodide and sodium hydroxide, with or without a non-freezing agent such as alcohol or a solution of common salt, lithium chloride, or brine. 'The electrodes may be made of platinum, silver, german silver, tungsten, magnesium, or any other chemical-resisting and non-oxidizable metal or alloy ; they may enter the containers at two or more points, or they may form parts of the containers. The connections to the electrodes may be reversible, or the containers may be turned round to change the polarity of the electrodes. A lesser and higher voltage may be applied to a single container for anti-dazzle and fog-penetrating purposes respectively, or two screens may be employed, the one containing the more concentrated solution being used only when a fog-penetrating light is required. The current for producing an anti-dazzle colour is preferably switched on automatically with the lamp. The screens may be arranged immediately in front of or behind the front glass or between the light source and the reflector. In the form shown in Fig. 1, the solution is contained in a flat pocket 3 formed by two clear glass or like discs 1 and an annular glass or metal spacing washer 2, whilst Fig. 2 shows the bulb b surrounded by two annular containers 4 having cambered peripheries 5. The containers 4 are provided with vent, filling, and emptying nipples 6, preferably fitted with valves or caps, and the electrodes are introduced through stems 7 carried by a cap 9 having contact pins adapted to engage in a socket 9d on the lamp. The containers 4 may be replaced by a single hollow ring or by a close helix of glass tubing, and a flat bulb container may replace the screen shown in Fig. 1 or be arranged horizontally over the top of the bulb b. Such a flat bulb container could also be provided with clips or rubber suckers for mounting it on the front of the lamp. Alternatively a flat bulb container 11, Fig. 6, and a lower coaxial annular container 12 may be supported above the bulb b by means of stems 13. A circular or other container 14, Fig. 7, is provided with uper connecting tubes 17 to provide an anti-dazzle light and with lower passages 18 to provide a fog-penetrating light. The passages 18 may be replaced by connecting tubes, and the connecting tubes may be close together at the top or throughout the depth of the screen, or they may be arranged vertically or otherwise.

Abstract: 400,041. Prospecting for minerals &c. PLANTA, G. U., 7, Place Jean Jacobs, Brussels. Jan. 24, 1933, No. 2326. [Class 37.] Apparatus for detecting metal objects, ores, or minerals buried in the ground or submerged in water comprises two independently displaceable coils 1, 2 forming two sides of a bridge, the other sides 3, 4 of which are formed by adjustable capacities and resistances, means such as a valve 9 and source of current 10 for supplying pulsating or oscillating currents to one diagonal of the bridge, and a detecting device, such as a telephone 7 and amplifying valves 8, in the other diagonal of the bridge. The various capacities, resistances, and valves are carried in a portable case 11, and the coils are mounted on crosses 15 with central insulating rods 14 to allow of their displacement. In use, the apparatus is first balanced in such a manner that, on neutral ground, no sound is heard in the telephone, then, one of the coils being stationary, the other is carried over the ground to be prospected. On approaching a buried metal object the balance of the bridge is upset, and a sound is heard in the telephone, the sound being at a maximum when the movable coil is vertically over the buried object. By varying the inclinations and positions of the coils, the distance or depth of the buried object may be deduced trigonometrically. The apparatus may be used in archµological researches, and for locating buried war materials, submarine wrecks, or submerged or buried cables.

Abstract: 808,714. Ignition systems. GUIOT, W. R. Jan. 23, 1957 [June 25, 1956], No. 2435/57. Class 7(4) An ignition system comprises a transistor arranged to produce high frequency electric oscillations, coupling means for feeding the oscillations to a sparking plug and a mechanically operated coupling varying member adapted to.be operated in synchronism with the rotation of the engine for controlling the feeding of the oscillations to the plug. The ignition timing may be adjusted by a phase displacing network in the high tension circuit. In Fig. 1 a PNP junction type transistor 2, 1, 4, associated withcoils 7, 9 and condenser 10 produces oscillations which can be fed to an high tension output terminal 13 by means of a booster coil 11 and a phase displacing apparatus 12. A disc 19, Fig. 2a driven at half engine speed is interposed between the coils 11 and the coils 7, 9 and the terminal 13 is connected to a distributer arm (not shown). Thus oscillations are fed to the distributer each time one of the apertures 20 in the disc is between the coils 7 and 11. The transistor 1 is disposed in the distributer housing. An NPN transistor may be used instead of the PNP transistor shown. Fig. 4 shows a modification in which there are separate coils 11a-11d and associated coils 7a-7d for each plug, the coils 7a; 11a not being visible in this Figure. The disc 21 has a single aperture not shown. Phase displacing networks, not shown, are included in the circuits of the coils 11a to 11d to time the high tension pulses as a function of the break frequency i.e. of engine speed. In Fig. 5 the coils 11 and 7, 9 are coupled' together inductively by the arms of a motor 24. This is the preferred embodiment for lower oscillation frequencie's. The system is powered by a vehicle battery 5. The frequency of the oscillator must be sufficient to permit several oscillations across the plug electrodes during the ignition time interval. A frequency above 30 kc/s is sufficient.
