Title: Improvements in or relating to navigation aiding radio beacon systems
IPC: G01S1/02
Filed: 1939-04-19
Abstract: 527,841. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEMP, R. J. April 19, 1939, No. 11771. [Class 40 (v)] Bearings are radiated from a beacon transmitter in the form of television signals superposed on a pair of constantly-reversed cardioid fields, the equi-signal line of which is made to rotate in space. Line-scanning impulses are sent out on both cardioids simultaneously with the picture signals, the frame impulses being confined to one only of the two radiated fields. At the receiving end, the length of the " line sweep", and therefore the size of the picture, is made to depend upon the strength of the incoming signal. The cardioid fields are radiated from a vertical aerial 15 coupled to a frame aerial 2, and energized from an oscillator circuit 8, the phase of the coupling being constantly reversed by two diodes 9, 10 at a frequency determined by the A.C. voltage supplied from a generator 17 and transformer 18. The frame 2 is constantly rotated by a motor 16 which also drives the generator 17, and a compass card 1. A small part of the card is scanned by a double-spiralled disc 20, Fig. 2, which is also provided with an outer ring of line-synchronizing slots b and a single " framing " slot c. The resulting output from the P.E. cell 3 is applied to modulate the radiated carrier. A second P.E. cell 23 receives light from a constant source to form the synchronizing impulses. The picture signals produced by the two spiral slots are applied alternately to the two cardioid fields. At the receiving end the two compass scale readings are shown on the fluorescent screen of a cathode-ray tube. They will appear of equal size only along the equisignal line. Outside that line, they will be unequal in size, as shown in Fig. 3. The size shown varies in accordance with the quarter of the compass in which the bearing lies, and this can be used to give an automatic indication of " sense." A directive aerial system and receiver may be used to produce the " reversed cardioid " effect on television signals radiated from a rotating-beam transmitter.

Rotary filters. - Filter leaves 28, Fig. 1, are supported longitudinally on a hollow rotary shaft 15, each leaf being connected to a separate pipe 25 within the shaft for the discharge of filtrate. Each leaf comprises a corrugated plate enclosed in cloth and having one edge inserted in a slotted pipe 33, Fig. 6. which is in communication with the corresponding pipe 25 by means of a fitting 36 which covers an apertune 35. The casing of the filter is in two parts bolted together, the upper part having a longitudinal opening 7, Fig. 2, closed by a plate 8, through which any filter element can be detached and removed. The lower part is shaped to accommodate a spray pipe 10 which is used to aid in detaching the cakes formed on the elements. The solid material is directed to a central outlet 13 by a screw conveyer 12. The material under treatment is supplied to the casing under pressure through pipes 43. The shaft 15 and associated parts are rotated by worm gearing 16, 17. The pipes 25 are supported in a member 23 which closes the end of the shaft 15. Outside the casing each pipe 25 is provided with a cock 46, Fig. 8, and a sight glass 47 and is continued by a sleeve 48 which enters a cored passage 51 in a member 52 which forms one wall of a filtrate-receiving chamber 55. The ends of the passages 51 can be simultaneously closed by a rubber gasket 62 on a spider 60 which rotates with the member 52 but can be moved longitudinally by means of a screwed central spindle 57. The passages 51 have connections 56 at right angles which are normally closed by a belt 66, but can be brought into communication with an air supply pipe 71 on the lower side. A modified form of filtrate-receiving chamber is shown in Fig. 10. An air or steam supply pipe 75 can be forced into engagement with the end of a passage 51 by means of a spring 77, but is held out of engagement during operation of the filter by means of a latch 80.

Abstract: 1,100,802. Testing converter valves. LICENTIA PATENT-VERWALTUNGS G. m. b. H. March 23, 1965 [March 23, 1964], No. 12183/65. Heading G1U. An arrangement for testing the ability of valves of the kind used in current converters to withstand blocking voltages incorporates a first oscillatory circuit including a capacitor 5 and inductor 6 in which the valve 7 to be tested is connected, and a second oscillatory circuit including the capacitor 5 and inductor 6 together with an auxiliary valve 4 and a much larger charging capacitor 3. The capacitor 3 is charged from a voltage source via a transformer 1 and charging valve 2. The valve 4 is then fired to partially discharge the capacitor 3 into capacitor 5 as the second circuit oscillates, the oscillatory cycle being interrupted when valve 4 becomes reverse biased. Thereafter the charge on capacitor 5 is reversed by firing the test valve 7. By periodically repeating this sequence, the charge on 5 builds up, so increasing the blocking voltage on the test valve.

Abstract: 297,044. Bargou, J. May 12, 1927. Plates and sheets, particularly of aluminium, for use in making containers &c. by welding, are formed with thickened edges b around a thinner central portion a, the thickness of that portion extending inwardly from the edge of the weld over that area which is affected by heat tending to reduce its strength after welding, being greater than that of the central portion by an amount sufficient to render both portions of similar resistance to stress. The ratio of the thickness of the central portion to that of the edges may be as 2: 3. The plate may be made by thinning out the central portion by rolling or beating. In one form the plate is rolled together with a sheet c of length equal to the width of the central portion and itself of small width. A series of passes may be .used of increasing depth, or the sheet may be replaced by one of greater width to continue the operation. The sheet c may have a deep central portion, Fig. 4, and thinner portions d extending over the thick edges b of the plates or two parts may be used for this purpose. Shaped rollers may also be used either alone or together with sheets. Two plates may be rolled simultaneously with sheets c between each pair. An aluminium sheet 8 mms. thick has edges 12 mms. thick and 200 mms. wide; the strength of the sheet is stated to be affected by heat for a distance of 150 mms. from the weld, which may be effected by fusion, pressure or spot welding.
