Title: Improvements in or relating to devices having dark trace screens
IPC: H01J29/14
Filed: 1944-11-14
Abstract: 621,729. Electric discharge devices. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 14, 1944, No. 22500. Convention date, July 22, 1942. [Class 39 (i)] A device comprises a screen consisting of crystalline alkali metal halide together with a smaller quantity of a compound of a polyvalent element in order to reduce the persistence of the dark trace produced upon the screen by bombardment with radiation. The proportion of the polyvalent element is not more than 30 per cent and may be approximately 5 per cent, based on the molweight of the alkali metal. The polyvalent element may be thorium, titanium, zirconium, hafnium, barium, cadmium, tin, lead, uranium, manganese, oxygen, selenium or sulphur. In the device shown in the drawing, the screen 5 on the window 6 of the cathode-ray tube 1 is viewed from the position 7 or 7a through window 6 or window 2, and consists of potassium chloride with thorium chloride. In preparing the screen, 0.462 grams of pure potassium chloride and 0.045 grams of pure octo - hydrated thorium chloride are weighed into a platinum container, thoroughly mixed and heated, preferably by radiation from a hot body, to a red heat (500-1000 C.), to avoid decrepitation until the two salts have melted or are well sintered together. The crystals of the mixed salts are supported at 10 in the small platinum container 12 with its open end facing the window 6 on which the halide screen is to be produced. The platinum container is preferably surrounded by an insulated resistance heater coil 14 which vaporizes the mixed salts 10 which arc condensed upon the window 6 to produce the screen 5. A screen prepared as described above or in an evacuated vessel other than the tube 1, and then transferred to the tube 1 through an atmosphere devoid of all moisture, if desired, may be subjected to an atmosphere containing either water vapour, ammonia or both, followed by sealing and evacuating the bulb. This treatment decreases the transparency of the target to white light and renders it more milky in appearance and increases the contrast between the appearance of the bombarded and unbombarded areas of the screen. The crystals of the mixed salts may also be comminuted and deposited upon the screen foundation by settling from a suitable gas or liquid suspension such as air or amyl-acetate. Several polyvalent elements may be present simultaneously such as both thorium and oxygen, in thorium oxide. The screen may be actuated by X-rays or ultra-violet light as well as a cathode-ray beam. Specification 513,776 is referred to. Reference has been directed by the Comptroller to Specifications 511,796 and 513,776.

Abstract: 480,004. Typewriters. IMPERIAL TYPEWRITER CO., Ltd., and ETHERIDGE, H. Aug. 19, 1937, No. 22790. [Class 100 (iv)] Sheet feeding and guiding arrangements ; columnprinting arrangements.- In frontfeed arrangements comprising an auxiliary carriage mounted on a support on the platen - carriage and provided with feed-rollers, a wheel for driving the feedrollers is mounted on the auxiliary car. riage, and has a splined or like connection with a manually rotatable shaft mounted in the support. The auxiliary carriage can be locked in different column positions by means of a catch. In the apparatus shown in Figs. 1 and 3, an auxiliary carriage consisting of end plates 28, 29 and cross-members is slidable on rods 12, 13 forming part of a support or bail 10 which is pivoted at the rear to the platen-carriage 18. A feed-roller 33 journalled in the plates 28, 29 co-operates with a feed-roller 32 which is journalled in spring-urged rocking arms 34, 35 on the plates, the arrangement enabling the feed-roller 32 to slew and thereby grip narrow sheets. A pinion 48 on the feedroller 33 engages a pinion 44 which is splined on a shaft 40 mounted in the support 10 and provided with a knob 42. A shelf 49 for a front-fed sheet is secured to a cross-member 30 of the auxiliary carriage and is supported by stays 30. The sheet is guided around the platen 24 by means of wire loops 59 or teeth on a bar 58 secured to arms 62, 63 on a shaft 64 mounted in the plates 28, 29. Before typing is commenced, the bar 58 is swung upwards, to prevent obstruction of the types, by means of a finger-piece 66 on the shaft 64. A spring in connection with the shaft holds the bar in either lower or upper position, the upper position being determined by a stop 60 on the bar. The auxiliary carriage is retained in various column-positions by cooperation of a catch-lever 51, pivoted on the plate 28, with notches 54 in the rod 13. For retaining the auxiliary carriage in positions intermediate of the notches, the plate 29 is provided with a screw 56 engaging the rod. To prevent the catch-lever 51 from being released when the bar 58 is in lower position; and to prevent the bar from being moved from upper to lower position when the catchlever is in released position, the shaft 64 is provided with a semicircular end 74 cooperating with an extension 76 of the catchlever. The bail 10 is swung upwards when the apparatus is out of use.

[Also in Division H3] A receiver, in a wired, radio or inductive selective calling system, will respond either to a signal of a particular frequency, say A, providing it exceeds a predetermined duration, or to a signal comprising three frequencies say A, B, C transmitted successively and repeatedly without breaks between them, e.g. A, B, C, A, B, C &c.,providing the sequence continues for more than the predetermined duration, and comprises a piezoelectric bimorph filter F (see Division H3), arranged to pass the three frequencies A, B and C, feeding a circuit comprising transistors T6, T7 and an RC circuit R16, C8 having a time-constant of the order of one second, the arrangement being such that with no output from the filter F transistors T6, T7 are both conducting and the potential across XY is substantially zero, but with an output from the filter F transistors T6 and T7 are both cut-off and the potential across XY begins to rise and providing the output from the filter is maintained long enough the potential will rise to the battery voltage. If however the output from the filter F falls off, even for a short period, transistor T7 will become conductive and the potential across XY will immediately fall to substantially zero. With this receiver by using only one or two frequencies as a call signal it is possible to call groups of receivers simultaneously.
