Title: Improvements in well logging apparatus
Inventor: BARLAI ZOLTAN
IPC: G01V3/24
Filed: 1959-10-09
Abstract: 939,757. Geophysical surveying. KOOLAJIPARI TROSZT. Oct. 9, 1959, No. 34358/59. Class 37. Borehole logging apparatus comprises a main electrode A 0  supplied with alternating current I 0  and focusing electrodes A 1 , A<SP>1</SP> 1  supplied with alternating current I 1 . The potential at measuring electrodes M 1 , M 2  is converted by a phase sensitive device to a direct current signal which it employed to regulate the focusing current I 1  so that the potential at electrodes M 1 , M 2  tends to zero. As shown in Fig. 3, the main current I 0  is generated by a variable frequency multivibrator 131, amplified at 132 and fed via a current limiting resistor to electrode A 0 . The output of the multivibrator 131 is also fed via a phase shifter 142 to the auxiliary grid of a heptode 141 and thence via an amplifier 15 to electrodes A 1 , A<SP>1</SP> 1 . The effect of this is to focus the current into a narrow beam through the walls of the borehole. The voltage at electrodes M 1 , M 2  is passed via a transformer 111, an amplifier 112 and a filter 113 (passing only the fundamental) to a summation circuit 121. A reference voltage is derived from the multivibrator 131 via a filter 123 and a phase shifter 124. The summation circuit 121 with a discriminator 122 provides a D.C. voltage, the sign and magnitude of which is dependent on the phase and magnitude of the potential at M 1 , M 2 . The D.C. voltage is indicated by a galvanometer and is fed to the first grid of the heptode 141 to control the current I 1  so as to tend to reduce the potential at M 1 , M 2  to zero. A selective amplifier 161, rectifier 162 and recording galvanometer are provided to monitor the potential at M 1 , M 2 .

Title: Improvements in or relating to colour photography
IPC: G03C7/00
Filed: 1935-12-11
Abstract: 471,586. Colour photography. HARRISON, G. B. Dec. 11, 1935, No. 34397. [Class 98 (ii)] Photographic material comprising two lightsensitive layers, one arranged to record substantially only one of the three primary colours, and the other arranged to record substantially only the other two primary colours in combination with a two-colour screen through which the second layer is exposed, the two colours of the screen being another primary colour and the colour complementary to it, which has been exposed to record one primary colour in the first layer and the other two primary colours in the second layer, is processed to produce in the first layer an image in the colour complementary to the recorded colour and in the second layer images in the colour recorded in the first layer, the images in the two layers and the colour screen being registered if necessary. As shown in Fig. 2, the material comprises a support having on one side a decolourable yellow-dyed blue-sensitive emulsion and on the other side a red and blue-green line screen and a panchromatic emulsion. The filter may be on a separate layer. A multi-colour screen positive is printed on to the material with its emulsion in contact with the blue-sensitive emulsion, using white light. Both emulsions are developed, reversed and fixed, and the image in the first layer is toned yellow, Fig. 3, e.g. by mercury toning, and the image in the second layer is toned blue, e.g. by producing a wash-out-relief by the use of a tanning developer and dyeing blue. If a negative master record is used the printed images are developed without reversal. Red, green and blue component negatives may be successively printed with appropriate lights on to material having a red sensitized silver chloride emulsion and an orthochromatic emulsion and an intermediate blue and yellow line screen. After development the first image is toned bluegreen by dye-mordanting or chemical toning and the second image is processed to a wash-out relief and dyed red. When printing multicolour screen originals filters may be used in the light-beam or the method described in Specification 417,860 may be employed. In taking, a bipack may be used having on one support the emulsion sensitive to only one of the primary colours and on another support the two colour screen and the second emulsion. The two emulsions may both be on the colour screen side of the support and may be processed by developing, bleaching, toning to the colour required in the lower layer, bleaching and toning the upper layer. Bichromated colloid or diazotype layers may be used. Specification 371,009 also is referred to.

Title: Emergency lighting unit
Inventor: COLE ARTHUR GEORGE WILFRED
IPC: B60Q1/44
Filed: 1954-11-29
Abstract: 801,897. Electric battery lamps. PHOENIX TELEPHONE & ELECTRIC WORKS, Ltd. Nov. 29, 1955 [Nov. 29, 1954], No. 34563/54. Class 39(2) [Also in Group XXXVII] An emergency lighting unit adapted for mounting on a vehicle, e.g. an aircraft, in which it becomes operative in the event of a crash comprises an insulating body 1 in which a lamp socket 4 is set and connected to terminals arranged to make contact with the terminals of a removable battery, switching being effected by operation of an inertia switch comprising a mass 14 which is normally held in an inoperative position in a channel by the pressure of a light spring 22 and movable within the channel to complete a connection between a battery terminal and the lamp socket. In the example, the movable mass comprises a metal ball 14, e.g. of silver-plated steel, located within a preferably cylindrical bore 15 in the insulating block 1, the ends of the bore being closed by flanged steel plugs 16 held in the block by steel strips 17 joined together electrically by a strip 19. The ball is normally held in midposition, clear of both plugs 16, by a spring- pressed plunger 21 which is recessed at its end to fit the ball and housed with its spring 22 in a metal tube 23 set in the block 1 on a radius of the cylindrical bore. An abutment screw 24 enables the spring- pressure on the ball to be adjusted, e.g. so that a predetermined minimum negative acceleration of one and a half times gravity will suffice to operate the switch. The free travel of the ball is less than its radius, so that when moved into contact with an end abutment 16 it retains contact with the spring plunger 21. To obviate the possibility of the inertia switch being actuated by gravity alone a permanent magnet 31 may be clamped between the steel strips 17 by a bolt 29 and, together with the adjustment provided by the spring-pressed plunger 21, the unit may be arranged to operate at any negative acceleration within a wide range, e.g. 0.7 g to 10 g, or more. To reset the switch after operation, and to switch off the light from the lamp bulb, the ball is returned to its neutral central position by a manually operable yoke or Y-piece 32 on a stem which is slidable within a face plate 2 integral with the insulating block 1, the two limbs of the yoke being provided with rounded ends which engage the ball when the stem is pushed inwardly, and restore it to mid-position. The ends of the limbs are also split so that in their inner position and with the ball central they bridge the gaps between the ball and the end plugs 16 and thus can hold the bulb circuit closed thereby providing a manually operated switch for testing and also when the lamp is detached for use as a hand lamp.
