Title: Improvements in or relating to screens for thermionic valves
IPC: H01R33/76
Filed: 1946-11-22
Abstract: 633,705. Thermionic valves. M-O VALVE CO., Ltd., and JAMES, E. G. Nov. 22, 1946, No. 34663. [Class 39 (i)] [Also in Group XL (c)] A thermionic valve is enclosed in a screen 1, Fig. 1, having an extension which provides electrostatic screening between at least two of the lead-in wires 7 projecting from the base of the valve. The screen 1 may be of a malleable metal or metal alloy, e.g. a lead alloy, and is made by making two cuts 2 near one end thereof and closing together the screen portions between the cuts and the adjacent screen end so as to form a single wing member 4. The member 4 serves as a screen for the leads 7 on opposite sides thereof, e.g. it may screen the anode lead from the control grid lead. Alternatively, by making four cuts instead of two, two intersecting wing portions at right angles can be formed. After the wing or wings are formed the valve is inserted into member 1 and the top of the latter is deformed as shown to hold the valve in position. Two rigid supports may be fixed on diametrically opposite positions on the cylinder 1 and may also extend along the sides of a single wing member. In an alternative method of manufacture the cylinder and single wing member may be formed by a moulding process. A spring clip 8 fixed to chassis 9, Fig. 3, serves as a holder for the valve and screen. The valve leads are soldered to tags 12 on the tag blocks 11 fitted on the underside of the chassis 9. Either the valve or the screen 1 may have a locating projection engaging a recess on the clip 8, e.g. the gap between the jaws thereof. Alternatively, the screen 1 and valve may be laid horizontally on the chassis and fixed to it by a clip. The valve leads may be connected directly to their associated circuit instead of via tag blocks, or may be in the form of rigid pins in which case a plug-in holder is used, the holder being formed so that it can also accommodate the wing portion of the screen 1. The valve may be provided with internal screening means as described in Specification 608,691, in which case the wing member or members may form a continuation of the screening means outside the valve. The Provisional Specification describes a form in which a rectangular metal sheet forming a wing is attached to one end of a hollow cylinder. The valve is inserted in the cylinder and is held in place by a spring which engages a rim at the other end of the cylinder. The tag block is a cylinder with a flange at one end by which it is bolted to a metal chassis and has tags at the other end. A metal socket is joined to the flange of the tag block and has a slot which engages with a prong on the valve screen. In another form the valve screen is integral with the metal chassis, and consists of two semicircular portions projecting below the chassis. In this case the valve has a screen covering all its surface other than its base, and has a spring clip holder.

Abstract: 1,208,761. Endless tape cartridge. AUDIO DEVICES Inc. 24 Nov., 1967 [25 Nov., 1966], No. 34743/67. Heading G5R. A cartridge for an endless magnetic tape, comprises a disc 13 for supporting a coil of tape 14 which is spaced at more than twice the width of the tape from the top cover wall 9 of the cartridge, a hub on which the tape is wound and an extension 36 to the hub on which loose tape unwound from the coil is received when the cartridge is not in operative engagement with a tape recorder. Normally, tape 14 is drawn from the inner convolution of the coil and passed via guides 16, 17 over magnetic heads entering apertures 8 in the cartridge wall, between a capstan and pinch roll 27 and via guides 18, 19, 20 back to the outer convolution of the coil. If the coil turns after being removed from the recorder then the tape leaving the coil winds on to the hub extension in a space defined by the extension and a part circular rib 29 extending downwardly from the top cover wall. Tape which leaves the coil but does not enter the storage space defined is maintained in the cartridge at the same height as the tape in the coil by means of levelling members 38, 39 extending downwardly from the top cover member and members 45, 46, 47 forming part of the base member. The tape in the coil is prevented from rising by a circular member 34 which also separates any tape on the hub extension from that forming the coil. A ramp member 48 is provided to shake out any loose tape coils which may form S-loops as the outer convolution forces the inner coils towards the hub centre. Pressure pads (not shown) are provided in the cartridge to urge the tape into engagement with the magnetic heads and the members which guide the tape in the vertical plane allow greater lateral movement of the tape after it has passed the tape drive position. Barrier means formed by members 24, 51, 52, 52<SP>1</SP> and 53 isolate a further loose tape storage space in front of the reel.
