Title: Improvements in or relating to gaseous conduction devices
IPC: H01J17/14
Filed: 1926-11-15
Abstract: 263,110. Raytheon Manufacturing Co., (Assignees of Smith, C. G.). Dec. 21, 1925, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus. -A gaseous conduction tube is provided with an inducing coil the field of which is restricted to the region of the cathode and away from the anode so that intense ionization is produced independently of the potential difference between the electrodes only in the region of the active surface of the cathode, gaseous conduction being produced at a low potential difference. In one arrangement, the cathode 2, Fig. 2, has the form of an incomplete hollow ring within which eddy currents in the gas are induced by the external high-frequency coil 11. current in the coil may have a frequency of 10<6> periods per second and its E.M.F. per turn preferably exceeds the ionization voltage of the gas or vapour, in which a current of several amperes may be induced. A tube 6 opening into the cathode dips into mercury 7 and may be heat-insulated at 8. It is surrounded by a collar 9 of magnetic material for heating it. The working pressure of the mercury vapour may be about 0.01 mm. The anode is a plate 10 in the plane of the gap in the annular cathode 2. A very low potential difference between the electrodes is suflicient, but mav need to be a little higher at starting. Such discharge devices, when used as rectifiers, can be connected in parallel without series reactances, or with small reactances only. In another construction, the cathode is an open cylindrical cup, its wall being close to the envelope and its base, in which is a central hole, being at a distance of about 1/16 inch from an anode disc. To avoid direct heating, tho cylindrical wall of the cup may be slit at intervals. A ring of magnetic material, heated by induced current to a temperature at which it emits electrons, is supported within the cup for starting purposes, aud connected thereto through an external current-limiting resistance. Argon, neon, helium, or the like is preferably contained in the device, which is surrounded by the highfrequency coil inducing eddy currents in the gas within the cathode. In a third construction, a hollow cathode has an opening in its top for the discharge to two rod anodes and communicates with a tube dipping in mercury. A heat shield surrounding the cathode has a corresponding discharge opening near the anodes and is slit so that eddy currents may be induced in the cathode and the gas inside, the high temperature of the cathode increasing the ionization of the gas. In a fourth construction, a closed conductor 33, Fig. 7, makes one turn 32 in the vicinity of an external high-frequency coil, and one or more turns near the anode 31, the gas being ionized either by eddy currents within the upper turns or by heat radiation therefrom. Radial shields 37 near the upper and a preferably insulating shield 38 near the lower turn, localize the eddy currents in the gas. Two anodes may be provided in all modifications. Specifications 246,036, 248,721, and 248,722 are referred to.

Abstract: 1,154,575. Sheet forming; seaming non- metallic sheet material. FARBWEBKE HOECHST A.G. 30 June, 1966 [30 June, 1965], No. 29497/66. Headings B5A and B5K. A pipe fitting is made by sheet forming each half of the fitting between a mould and an associated core, exposing the rim of each half whilst it is retained within its mould, heating the exposed rims and finally moving the moulds together to weld the two halves into an integral fitting. In the embodiment shown in Fig. 1, halves 5, 6 of a branched pipe fitting are formed between mould halves 1 and 2 and cores 3 and 4 respectively. The top layer of a facing 8 is then removed from each mould half to expose the rim of each half 5 and 6, a heating plate inserted between the mould halves, and mould halves forwarded together to press the rims against the plate. The mould halves are subsequently retracted, the heating plate removed, the lower layer of each facing removed, and the mould halves re-forwarded to press the rims together and complete the formation of the pipe fitting. In a second embodiment, see Figs. 5 and 6 (not shown), a single sheet is bent around a core and the core enclosed by two mould halves to preliminarily form the fitting. Facing layers are then removed from the middle of the core and the mould halves and a heating plate substituted against which the rims of the fitting are pressed, said plate subsequently being removed and the mould halves moved together again to form the complete article as before. In this case the welded seam only extends partway round the fitting. In a third embodiment (see Figs. 7 and 8, not shown) the mould halves and the core are foldable about a hinge from a flattened position to a position in which the mould halves surround the core.

Relates to a circuit for developing a deflection correcting component, for example for producing a trapezium-shaped area on a target perpendicular to the direction of the undeflected electron beam or a rectangular area on an inclined target. A frame frequency pulse plus a sawtooth signal, Fig. 2A, is applied to terminal 1, Fig. 1, and the signal of Fig. 2B appears at one grid of a valve pair 6, 10. The anode loads of these valves comprise valve pairs 19, 20 and 21, 22. Waveforms C and D, Fig. 2, are those of the currents in valves 6 and 10 respectively. It is arranged that valves 19, 21 are conductive when valves 20, 22 are non-conductive. Line frequency pulses, Fig. 2E, are applied to terminal 28 and are of sufficient amplitude to cut-off valves 19, 21 so that valves 20, 22 now conduct. The pulses developed by valve 21 and valve 20 are as in Figs. 2G and F and combine to give an output, Fig. 2H, at terminal 31. The output is fed to a scan generator to develop currents of which the rate of change is dependent upon the amplitude and polarity of the applied pulses. Such a generator is described with reference to Fig. 3 (not shown).
