Title: Improvements in or relating to thermionic oscillation generators
IPC: H01J25/72
Filed: 1931-06-01
Abstract: 379,395. Generating high-frequency oscillations. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Usselman, G. L. ; Port Jefferson, Long Island, New York, U.S.A.) June 1, 1931, No. 15993. Convention date, June 27, 1930. [Classes 39 (i) and 40 (v).] In thermionic oscillation generators of very short wavelength, electrons passing from a cathode to an anode are deflected so that they follow alternate paths longer than the shortest distance between the two electrodes, the electrons impinging on the anode without overshooting it and generating oscillations in it at its natural frequency. The anode A, Fig. 3, is a rod one-half wave-length long acting as antennµ and may be coiled at its centre to decrease the percentage of energy radiated and so increase the stability of the generator. The cathode C partially surrounds the centre of the anode as in Fig. 2. The paths of the electrons are increased by negatively charged screens B, S about the centre of the anode and about its central lead D and may also be increased. by the electromagnetic field of a coil G having its axis parallel to the anode. Electrons pass to alternate sides of the anode and the potentials on these sides alternate so rapidly that the electrons do not reach each side until it has become negative. A parabolic reflector R an odd number of quarter wave-lengths, preferably one quarterwavelength, behind the anode A provides directional transmission. Taps symmetrically placed on the anode may supply a transmission line. Radiators spaced from the anode A may be alternately tuned to propogate energy towards or away from a receiving station. The oscillations may be modulated by a transformer in the anode lead or in the circuit of the coil G or in the lead to the screen B, an alternating current source and a key being used in the last case in the primary circuit of the transformer.

[Class 8 (ii).] In apparatus for grading dust particles or separating dust particles from gases, of the kind in which a dust laden gas is introduced at the bottom of a casing A, Fig. 3, which traps the heavier dust particles and from which the gas carrying the lighter particles is evacuated at the top, the gas inlet and outlet devices B, B<1> consist of a series of flat rings b<3>, Fig. 5, spaced axially and of diminishing diameter so as to distribute the gas evenly. For multiple grading, a number of outlet devices B<1> may be provided at different levels, or the arrangement shown in Fig. 4 may alternatively be used in which the outlet B<1> is in the form of concentric annular passages each with a number of superposed rings of diminishing diameters. As shown in Fig. 3 dust to be graded is introduced by a funnel f into the inlet of a fan F which distributes the dust laden gas by a manifold D and inlet pipes b<2> to the casing A. The exhaust gas passes from the casing by the pipes b<4> either to dust collectors H or to another apparatus or in a closed cycle to the same apparatus for further treatment, the heavy particles collecting at the bottom of the casing and being withdrawn therefrom. In the modification shown in Fig. 6, the pipe D to which the dust is admitted by the funnel f<1> forms an annular passage with the outlet pipe J of the fan, and the casing A has a bottom a<2> provided with tapering inlet passages a<3> so that gas directly from the fan acts to remove any of the fine particles that are entrained with the heavy particles discharging from the casing.

Abstract: 310,015. Steel & Tubes, Inc., (Assignees of Hallden, K. W.). April 21, 1928, [Convention date]. Shearing.-A machine for servering moving articles, such as tubes, into predetermined lengths comprises a shaft 21, Figs. 5 and 10, driven through a one-revolution clutch and provided with heart-shaped cams 23 for actuating a carriage 6 in which a cutter 12 is vertically reciprocated by eccentrics 26. The cutter is guided in the carriage by rods 9 having lugs which actuate positively in both directions a pair of guides 13 provided with bushes 15 which clamp the work during the severing operation and release it on the upward stroke of the cutter. The shaft 21 carries at one end a constantly applied brake 31 to prevent overrunning and at the other end a loosely-mounted clutch member 56 driven through bevel-gearing 57 by a shaft 59, Fig. 1, whose drive is taken at 61 from the main shaft 63, the latter shaft also driving rollers 64 for feeding the work into the machine.

Title: Improvements relating to radio navigational systems for aircraft

Filed: 1945-06-28
Abstract: 625,891. Radio navigation. COSSOR, Ltd., A. C., and BEDFORD, L. H. June 28, 1945, No. 16552. [Class 40 (vii)] In order to define a flight path not coincident with the path defined by a beacon transmitter, the beacon-receiving apparatus on the craft has its functioning modified in accordance with the range to the beacon as measured by radar methods. In the system shown, a course is defined by the axis of rotation of a conically scanned radio beam. The craft carries a receiver 1, 2, 3, the output from the detector V of which feeds a low-frequency amplifier 4 providing outputs on leads L1, L2, representative of the lateral and vertical misalignment between the craft and the axis of beam rotation. A radar range-finder 5, 6, 7, 8, 9 on the craft co-operates with a responder beacon on the ground to provide an output from the common circuit 7 in the form of a shaft rotation representing the distance of the craft from the landing ground. This shaft rotation controls a potentiometer R1 which feeds a D.C. biassing signal from the detector output in series with the output on lead L2. Leads L1, L2 feed an indicator such as a crossed pointer meter, or an automatic pilot. The draft is thus constrained to fly on a course which deviates below the axis of rotation of the beam to an extent which is a function of range, and due to the derivation of the biassing voltage, the deviation is independent of precise operation of the receiver A.G.C. circuits. In an embodiment of the invention giving a straight line glide path, the biassing voltage which is required to be inversely proportional to range, may be obtained from the D.C. component of the rectified beam signals prior to A.G.C. action while the angular misalignment signals are obtained from subsequent stages subject to A.G.C. Specification 582,081 is referred to.
