Title: Improvements in or relating to vacuum tube circuits
IPC: H03F3/22
Filed: 1930-11-14
Abstract: 367,022. Valve amplifying circuits. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Reynolds, J. L. ; 3751, 89th Street, Jackson Heights, New York, U.S.A.) Nov. 14, 1930, No. 34313. Convention date, Dec. 31, 1929. [Class 40 (v).] A thermionic amplifier comprises at least one pair of similar valves connected in parallel or in similar parallel circuits, the cathode of each valve being heated by substantially equal alternating currents flowing in one direction in one cathode and in the opposite direction in the other, whereby the effects of the heating currents in the two valves neutralize each other in the output circuit. Fig. 1 shows the input from a source S applied to two parallel primary windings 3, 4, of transformers 5, 6, the split secondaries 7, 9, 8, 10 being connected to two push-pull pairs of valves 15, 17, 16, 18. The filaments of each pair of valves 15, 17, 16, 18 are heated from the separate secondary windings 53, 54 of a filament transformer, the connections being such that when the cathode of 15 is positive with respect to the cathode of 17, the cathode of 18 is also positive to the cathode of 16. By this means the hum component due to each pair is delivered in opposite phase to the paralleled secondary windings 37, 38 of the output transformers 31, 32 and thus cancels out. The primary windings of the input and output transformers 5, 6, 13, 32 may be in series instead of in parallel, Fig. 1A (not shown), or a single transformer may be employed in each case, with one primary and four secondaries for the input transformer, and four primary and one secondary -winding for the output transformer, Fig. 1B (not shown). Fig. 2 shows an arrangement in which a pair of valves 105, 107, connected in parallel, are arranged in push-pull with another parallel pair 106, 108. The filaments of valves 105, 106 are supplied in series by the secondary 154 and the filaments of 107, 108 by the secondary 153. The arrangement operates in a similar manner to that of Fig. 1. Alternatively the filaments of the parallel valves 105, 107 and 106, 108 may be in series across the respective secondary windings 154, 153, the effect being precisely the same as in Fig. 2, (Fig. 3 not shown). The invention may be applied to radio or audiofrequency amplifiers.

Abstract: 961,190. Cameras for recording the roll of missiles. COMMONWEALTH OF AUSTRALIA. Oct. 7, 1960 [Oct. 9, 1959], No. 34487/60. Drawings to Specification. Heading G2A. A method of recording roll of missiles relative to the ground or other reference, comprises obtaining a photographic record of an arc from the missile of at least 180 degrees in a plane which intersects the horizon or other reference using a wide angle lens camera, the field of view of which is limited by passing the image through a slit and moving the film transversely to the slit whereby the image of the horizon or other reference produces a line in said film. More than one camera can be used for example two cameras may be used either facing the same direction with their slits at right angles to each other or facing in opposite directions with their slits parallel. A tuner lamp may be included in the camera to record time interval on the film.

Abstract: 378,746. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Dec. 12, 1931, No. 34540. [Class 130.] In wrapping- mechanism c o m - prising a nest of rollers 5 .. 8, the end of the wrapper W is passed around the head end of the bunch by a bending or ironing device 16 pivoted at 12 and shaped to extend over one of the rollers 8. The pivot 12 is fitted with a spring which presses the device 16 on to the bunch when the tail portion 19 of the member is allowed to move into the full-line position by a guide 20 acted on by a cam 28. The head of the bunch rests upon a block 15, and the rollers 7, 8 extend to the tip of the head. The roller 7, rotating in the direction indicated by the arrow, exerts a drag on the end of the wrapper W and maintains it in tension after it has become released from the tensioning-plate 22. The rollers and the device 16 are carried by levers 23, 24, which are opened about a pivot 25 to admit a fresh bunch.
