Filed: 1974-04-22
Abstract: 1471954 Testing and identifying wires in cables PERKINS RESEARCH & Mfg CO 22 April 1974 [20 April 1973] 17557/74 Heading G1U In a method of detecting faults in a cable or identifying conductors in a multi-way cable, a tone generator is connected to one end of the cable and a receiver probe is first coupled to the generator or the cable near the generator to enable the receiver to be accurately tuned to the generator frequency and is then moved along the cable to locate a fault or used at the other end of the cable to identify conductors. In fault location, a coil 13 which may be on the end of a pole 15 is used as the probe, the generator 12 is connected to a twisted pair of conductors 21 and the coil brought close to this end. The receiver unit 16 is then tuned by operating switch 51 to select a level frequency response for the second stage of the receiver amplifier. The first frequency selective stage is then adjusted to give maximum output from loudspeaker 26 or headset 27. The switch 51 is then cancelled and the second stage now becomes frequency selective, this being adjusted 49 for maximum output. Overall sensitivity control 71 is also provided. After setting up, the coil 13 is moved along the cable until a change in its output is detected, indicating a fault. A similar procedure is used for conductor identification except that a direct contact probe (14), Fig. 2 (not shown) is used, the receiver sensitivity being such that the proximity of the probe to the conductor ends provides enough capactive coupling to enable approximate idenfication, final identification being completed by direct connection.

Title: X-ray image intensifier system
IPC: H01J31/48
Filed: 1954-06-15
Abstract: 770,459. Television pick-up tubes. HUGHES AIRCRAFT CO. June 15, 1954, No. 17579/54. Class 39(1). [Also in Group XL(b)] A system for prolonged visual presentation of an X-ray image of short duration comprises a camera tube 10 with a negative feedback circuit 16, including a video amplifier 41, between the secondary electron collector and signal electrode 27 and a transparent electrode 32 backing the photo-conductive target 33. The signal is also fed, through a video amplifier 45, to the display tube 14. The potential of an elemental scanned area is shifted to a stable potential where the secondary emission ratio is unity so as not to erase the charge pattern. The charge pattern is produced by conduction through the photo-conductive layer, of charges liberated by light from a fluorescent layer 30. Where the charges are electrons e.g. with a photo-conductive target of antimony trisulphide, the charge image is discharged by the scanning beam in a positive direction and the effect of redistribution of secondary electrons is small. Where the charges are " holes e.g. with a photo -conductive target composed of red vitreous selenium, a flood gun is provided to direct high energy electrons uniformly over the target. The surface of the target is charged negatively at a faster rate than the holes change it in a positive direction, and the charge image is as before, discharged in a positive direction by the scanning beam. The charge image may be erased by disconnecting the feedback circuit. A synchronizing pulse opens switch 105, through relay 107, just prior to operation of the X-ray source. Specification 754,752 is referred to.

[Also in Group XXIV] A price and cost indicator for a liquidmeasuring apparatus, the indicated price on which can be altered as desired comprises a displaceable gear-wheel mounted in a swingable frame and adapted through intermediate means to transmit the values to be measured to a totalizer, said displaceable gear being slidably but non-rotatably mounted on a shaft supported in said frame, displacement of said gear-wheel being effected by means of an arm carried by a threaded spindle, said spindle also being provided with a disc having a notch in which a pin carried in said swingable frame normally rests, a set of pinions spaced along and freely rotatable about a further shaft, which pinions are rotated at different speeds and are individually engageable with said displaceable gearwheel, the arrangement being such that rotation of said spindle through 360 degrees causes displacement of said gear-wheel along its shaft through a distance corresponding to the mutual spacing of said pinions and causes said pin to be lifted out of said notch to effect disengagement of said gear-wheel from said pinions by rotation of said frame. The shaft 1, Figs. 1 and 2, driven by the meter carries a cone of nine gears a which through the gears b drive the pinions c, which are free on a spindle 2, at speeds varying in proportion 1-9. A gear-wheel 5 is slidably but non-rotatably mounted on a spindle 7 carried by a frame 9 swingable on a spindle 10. The spindle 7 is connected to a totalizer (not shown) through the gears 8 and 11. The gearwheel 5 is connected to an arm 17 of a nut 16 movable along a shaft 14 by the thread 15. The shaft 14 is connected to a price indicator through the worm 24, the worm-wheel 21 and the pinion 23. The shaft 14 carries a disc 13 having a notch 19 in which a pin 12 attached to the frame 9 normally rests. Upon rotation of the shaft 14 by the knob 18 the disc 13 effects rocking of the frame 9 so that the gear 5 leaves the pinions c, continued rotation of the shaft 14 up to 360 degrees effects movement of the gear 5 along the spindle 7 to the next pinion c. A pinion 4 fixed to the spindle 2 adjacent the pinions c may be engaged by the gear 5. A plurality of gears 5 and associated parts may be provided.
