Filed: 1946-04-18
Abstract: 610,977. Duplex radio signalling. CINEMATELEVISION, Ltd., MORGAN, M., and GRAHAM, G. E. G. April 18, 1946, No. 11957. [Class 40 (v)] Signals are relayed in either of two directions by switching a receiver and a transmitter between two aerials, either of which can be used for transmitting or receiving. Duplex working is achieved by rapid, synchronized switching. Signals received at aerial 2, Fig. 1, pass via channel A, E, H to a receiver and demodulator 3, modulator 4 and transmitter 5, and to the transmitting aerial 6 via channel C, D, F. The channels are an integral number of half-wavelengths long, the unwanted pair presenting an infinite impedance by being short-circuited at the mid-point by switch elements B, G, e.g. diodes controlled by a trigger circuit 8. Conversely, signals may be received at 6 and transmitted at 2 by closing switches D, F, and opening switch B, G, to use channels F, G, H and C, B, A. When the channels comprise wave-guides, the short-circuiting elements may be gas switches triggered by local oscillating signal generators. In a modification, Figs. 3 and 4 (not shown), interlocked mechanical switches are used to open and close the channels. In a further modification, Figs. 8 and 9, an occulting disc with semi-circular slots 23, 24, opens and closes the channels LM, JK, and OK, LN, in turn as it is rotated by a synchronous electric motor 22.

Abstract: 1,173,293. Electronic counters. ENGLISH ELECTRIC CO. Ltd. 14 March, 1967 [18 March, 1966], No. 11960/66. Headings G4A and G4H. Errors in the indication of the displacement of a member from a datum position are detected. A pulse generator 10 responds to movement of the member 9 by producing forward or reverse count pulses on one or other of leads 11, 12 and 90 degrees displaced waveforms of one-quarter the frequency on leads 13, 14. The latter are differentiated at 36, 37 and fed to circuits 40, 41. The count pulses are delayed at 33, 34 and also fed to 40, 41. In normal operation the pulses due to waveforms 13, 14 alternate with the delayed count pulses so that error detection circuits are primed and reset alternately. If however two count pulses are received in succession or a count pulse is omitted, then circuit 40 or 41, as the case may be, signals circuit 42 to reset the counter 17 and signal controller 32 to inhibit further operation. The counter 17 is reversible, the direction of count being controlled by leads 20, 21. When the counter passes through zero it signals detector 25 to reverse sign selector 24 and count direction controller 32. The counter comprises a number of decimal stages 44 monitored by a like number of quinary stages 45, lack of coincidence resulting in the corresponding denominational display 47 being ineffective.

Abstract: 109,283. Sinclair, T. C. Aug. 30, 1916. Plane-trigonometry calculators. - Relates to apparatus for solving plane triangles, given any three elements, with a modification adapted for right-angled triangles. In the form shown in Fig. 1, a first member A carries at one end a graduated arc D upon which moves an index-pointer C' borne by a second member C secured to the opposite end of the first member by a pivot B. Each of these members is slotted to receive blocks carrying pins O, T, of which the pin 0 forms a pivoting centre for a third member E, while the block for the pin T carries a part adapted both to slide in a similar slot in the third member and also to turn upon the pin. Triangles can accordingly be formed having the sides and angles of any desired values. Each of the three members has length-graduations upon a similar scale, the angles being set or read upon the graduated arc D and also upon graduated semi. circles E<2>, J fixed to the third member and read against index-pointers G, K sliding in the slots of the first and second members. Upon the insertion of a pin through a central aperture E<5> of the semicircle E<2> into a hole G<2> in the corresponding index-pointer slide, whereby the angle between the first and third members of the triangle is limited to a right-angle, the apparatus is readily applicable for computing distance, from the angle subtended at the observing-station by a vertical object of known height at the distant point. To facilitate this there may be an amplified false scale of small angles upon the arc D carried by the first member, and a corresponding amplified scale of lengths, for example heights, upon the third member, the use being approximate and based on the assumption that the sine or tangent of a small angle is proportional to the circular measure.

Abstract: 827,739. Space - charge - wave tubes. GENERAL ELECTRIC CO. April 24, 1956 [April 28, 1955], No. 12523/56. Class 39(1). A space-charge-wave amplifier has a number of electrodes 33, 34, Fig. 1, spaced along the beam and maintained at potentials alternately above and below the mean beam potential, so that a cyclic variation of potential is impressed upon the beam the variation having a wavelength of one-half the plasma wavelength. As shown the cathode 12 forms the inner member of a coaxial-line input resonator closed by grid 16 and the beam after passing accelerating grid 24 traverses the electrodes 33, 34 to output resonator 26. The electrodes 33, 34 are catenoids sealed together by insulating discs 35 to form the envelope and maintained at, say, 100 volts above and below a beam voltage of 1000, the shape chosen produces a nearly sinusoidal variation of potential along the axis. Magnetic focusing is employed. In other forms the electrodes are short cylinders disposed inside the envelope, or a bifilar helix 50, 51, Fig. 3, may be employed. The input and output circuits may also be rhumbatrons or helices. A detailed mathematical discussion of the effect of the voltage variation in producing space-charge-wave amplification, is given.
