Title: Improvements in or relating to luminescent materials
IPC: C09K11/55
Filed: 1942-10-08
Abstract: 562,270. Luminescent materials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 8, 1942, No. 14124. Convention date, Oct. 30, 1941. [Class 39 (i)] A luminescent material which is the salt of an oxygen-containing acid, such as a silicate or germanate of zinc, zinc-beryllium or zinczirconium or a tungstate, is mixed with a higher oxide of a metal which is reducible to a lower oxide form without appreciable reduction to metal. The admixture prevents blackening by reduction which otherwise occurs when the luminescent material is used in a cathode-ray tube or lamp, especially when an oxygenremoving getter is present. The metal may be calcium, strontium, barium, vanadium, chromium or manganese, but tin is unsuitable; barium peroxide is the preferred addition. The percentage addition may range from 0.1 to 20, but about 2 is the preferred figure, although a higher proportion is useful in high-intensity projection tubes. The mixing may be performed in a ball-mill. Another luminescent oomponent, such as an equal amount of zinc sulphide, may be added.

Title: Improvements in or relating to apparatus for examining bodies by means of x-rays or other radiation
IPC: G01N23/04
Filed: 1933-05-16
Abstract: 403,010. R÷ntgen - ray apparatus. MULLER AKT.-GES., C. H. F., 24, Rontgenstrasse, Hamburg, Germany. May 16, 1933, No. 14188. Convention date, May 20, 1932. [Class 98 (i).] A source of rays such as an X-ray tube, or a radium cylinder, for examining the condition of objects, determining the thickness of walls, &c. is magnetically held in position during operation. The fluorescent screen, photographic layer, ionisation chamber, or other ray-receiver may also be magnetically held. Apparatus shown in Fig. 2, for examining a wall 7, such as a ship's side, comprises a ray tube 1 carrying at each end an iron yoke 4 bearing magnetizing coils 5. The tube is suspended by a chain 2 connected to the yokes, and is held in definite position against the wall 7 by energizing the coils 5. If the wall 7 is non-magnetic, the tube may still be held in position magnetically by the action of steel bars 10, which are placed on the opposite side of the wall, and are designed to hold the screen or other ray-receiver 9. The proper position for the receiver 9 is determined as that in which the bars 10 are most strongly held, or may be found by exploring with iron filings or a magnetic needle. If the yokes 4 have residual magnetism strong enough to hold the tube in position, the magnetising current may be cut off after it has magnetised the yokes ; and the tube may be released by passing a reverse current through the coils 5. In a modification, for examining a profiled iron bar, there are only two magnetizing coils, each mounted on one arm of a yoke whose central portion is hollow and envelops the ray-tube ; and the arms of the yoke are fitted with interchangeable pole-shoes in order to adapt them to rest firmly against profiled bars of different shape. In another form, Fig. 7, the chain 2 is replaced by a magnetic body 25 on which is adjustably mounted a slide 26 articulated by a link 27 to the yoke 24 for holding the ray-tube 23 against the object under examination. Vertical adjustment of the ray-tube is permitted by the slide 26, and horizontal adjustment by providing a ball and socket joint at each end of the bar 27. A further modification is described fitted with a pair of tungsten wires for use in determining the thickness of a wall after the manner described in Specifications 383,478 and 383,806. The ray-tube is so placed that its discharge path is either situated in a space free from magnetic field, or is so directed that its magnetic field coincides in direction with the magnetic field of the holding device.

Abstract: 1,106,978. Drafting apparatus. JAMES MACKIE & SONS Ltd. 2 July, 1965 [7 April, 1964], No. 14336/64. Headings DID and D1F. In a drawing-frame, the upper roller of a drawing pair is loaded at each end by a tensionmember which extends downwardly to a pre-set spring-loading arrangement having a control for relieving the pressure and which tensionmember is connected at its upper end to a member by which the loading pressure is transmitted to the roller; in each case the connection to the loading member is adjustable to vary the relative position of the tension member and the loading member as shown by an indicator. At each end of the shaft 8 of the upper pressure roller 5 is a hook 9 attached to a tube 10 pulled downwardly by a spring- loaded chain 11. The top of each tube constitutes a bearing-surface for a stop 41 connected to the chain 11 which is inside the tube. Each chain is pulled downwardly by a spring 17 encircling the tube and compressed between a fixed upper stop and a lower stop 15. The stops 41 and 15 are each adjustable along threaded rods attached to the chain; the loading is pre-set by adjusting the stops 15 to an extent indicated by a pointer attached to each of the upper threaded rods which cooperates with a scale on the corresponding tube. After the loading has been pre-set, without dismantling the machine, further adjustment may be made, or the pressure be restored to its original value after the roller has been re-surfaced, by adjusting the stops 41. The fixed stops against which the springs 17 are compressed are carried by a bridge 18. This is connected by a rod 19 to a link 20 eccentrically and pivotally connected to a disc 21 secured to a rod 22 to which is connected an arm 25. During working, the springs 17 are kept in tension by locking the arm by a latch 28 which engages a fixed stop 29. The latch is released by depressing a pedal 32, whereby the load is relieved, and the arm is freed to be turned through 180‹ so that the hooks 9 can be lifted off the shaft 8 for removal of the roller.
