Filed: 1928-01-19
Abstract: 288,239. Electrical Research Products, Inc., (Assignees of Gray, F.). April 6, 1927, [Convention date]. Television.-A television receiver for use with a transmitter T, Fig. 1, similar to that described in Specification 288.238 comprises a neon lamp provided with a large number of internal electrode elements arranged to form a grid-like display board or field of view. The lamp consists of a number of parallel sections 200, Fig. 3, joined at alternate ends to form one long glass neon tube. An internal electrode comprising a spiral 202 is contained in each section, and all these electrodes are connected to the common return conductor 204. At the back of the tube (seen in Fig. 3) a large number of tinfoil or like electrodes 203 are fixed externally; these are connected by springs 220, Fig. 7, to contacts on a large panel 120, which are in turn connected to tabs 116, Fig. 6, and so to conducting segments 115 on a rotary distributor 110, Figs. 1 and 6. The distributor segments are arranged in staggered rows so that they contact successively with a brush 111 which is rotated by a lowfrequency motor 101 and an associated highfrequency motor in synchronism with the scanning device at the transmitter T. The field frames of the motors can be rotated manually for the purpose of phase-adjustment, and the successive energization of the electrodes 203 at high speeds, under control of the signal currents as described below, gives a persistent, visual impression of the transmitted picture. Signals received over the line 40 are amplified and applied to an oscillator-. modulator OM70 and high-frequency oscillations, modulated accordingly, pass to the display lamp through the leads 81, 82 and commutator 110. A constant excitation is also supplied from the oscillator 090 via leads 82, 83, internal electrode 202 and an external electrode 205 which is common to all the sections 200 of the lamp. In a modification the internal helical electrode 202 may be replaced by a common external electrode such as a sheet of wire gauze through which light can pass. The long neon tube 200 is connected to a gas-purifying chamber 212 containing pure magnesium electrodes 213, 214. A d.c. electromotive force of 150 volts is applied to the electrodes and the resulting discharge has the effect of purifying the gas. Specification 288,234 also is referred to.

Abstract: 747,175. Waveguides. SPERRY CORPORATION. Jan. 25, 1952 [Jan. 25, 1951], No. 2174/52. Class 40 (8). [Also in Group XL (c)] Coupling between two coaxial, rotatable ring wave-guides is effected through openings in the adjacent faces. The degree of registration of the openings and the coupling, is determined by the relative displacement of the rings.. As shown, the wave-guides 13, 15 are relatively rotatable about the central axis and energy fed into 13 at 17 is transferred to the utilization device at 19 from wave-guide 15. The opposing walls of the internal cavities have arcuate-openings whch may have cross-bars 57 to provide enhanced discrimination against energy transfer in the reverse direction. Escape of energy between the upper and lower ring units is prevented by serrated -wavelength chokes 41, 43 which surround the units. An arcuate plate is secured in each waveguide below arcuate openings to prevent energy reflections from the ends of the openings and to maintain uniformity of phase velocity of energy propagation throughout the wave-guide. A ball-race may be introduced between the mating faces of 13, 15 to reduce friction. In a radar scanning system, Fig. 8, the antenna 61 is rotated round the mast 62 by the motor 65 and coupling between 61 and the feeder 63 is effected through the coupling 13, 15.

Title: Improvements in metal spraying
IPC: B05B7/18
Filed: 1922-01-27
Abstract: 196,694. British Metal Spray Co., Ltd., and Gillespie, W. M. Jan. 27, 1922. Enamelling, vitreous.-A process of spraying enamel consists in feeding it towards a heating appliance wherein it is heated indirectly by radiation and/or conduction by surface combustion means in such a way that any contact of the enamel with the flame is prevented, and the enamel is blown against the surface of the object to be coated by a blast of air or other gas. For this purpose use is made of a nozzle of porous or granular refractory material adapted to be heated to a high temperature by surface combustion means. The refractory material may be used for heating the blast and means may be provided for removing the products of combustion or they may issue with the blast. The temperature of the nozzle is regulated in accordance with the rate at which the enamel is fed to the apparatus and in such a way as to keep the enamel below its oxidation temperature. The nozzle may be surrounded by a tube so as to provide a conduit for the air or gases which supply the oxygen used for the combustion of the gases heating the refractory material.
