Void [Abridged as open to inspection under Sect. 91 of the Acts, May 18, 1935]. [Classes 20 (ii) and 20 (iv)] Composite constructional members, stated to be suitable for use as ties or braces in lattice girders, as concrete reinforcement, and as cable sections in a suspension bridge where they take simple compressive or tensile loads, are composed of at least two different materials one of which A is subjected to tension and the other B to compression by reciprocal action. It is stated that materials of high tensile resistance, such as steel, can be thus combined with cheaper materials having high compressive resistance, such as cast iron, concrete, earthenware or glass.

Title: Improvements in or relating to electric signal transmission systems
IPC: H01B11/00
Filed: 1935-11-22
Abstract: 466,418. Transmission systems. BLUMLEIN, A. D. Nov. 22, 1935, No. 32471. [Class 40 (iv)] [Also in Group XXXVI] A concentric cable for transmitting a wide range of frequencies is provided with an additional conductor which in conjunction with the central conductor forms a balanced circuit for the lower frequencies for which the outer conductor is less effective as a screen against inductive interference. The additional conductor 4 with a paper covering 5 lies within a helical groove in the paper sheath 3 surrounding the central conductor 2. The latter is deformed in the manner described in Specifications 452,713 and 452,772, [both in Group XXXVI]. and the conductor 4 is arranged to have substantially the same length. The outer conductor comprises a thin layer of copper foil 6 overlaid with lead sheathing 7. Alternatively the additional conductor may lie within a lead sheath outside the lead sheath 7, both sheaths being contained in a common outer sheath. The additional conductor may also lie in a straight groove in the paper sheath 3, the lead sheath 7 being egg-shaped in cross-section, and four such cables may be combined to form a multiple cable in which the positions of the additional and central conductors may be rotated. The additional conductor may also consist of two or more separate conductors wound on the paper sheath 3. Circuits. In order to minimize interference the attenuation and velocity of propagation of the two circuits comprised respectively by the central and outer conductors and by the central and additional conductors should be approximately equal at low frequencies. The central conductor 2 is loaded at intervals with condensers 9 shunted by resistances 10 in the manner described in Specification 455,492, and also with condensers 11 to correct for the low-frequency effect referred to in the latter Specification. Condensers 12 in the additional conductor 4 maintain the ratio of the capacities between each conductor and the sheath. The line is terminated by condensers 13, 14 and a resistance 15 in series, and is coupled to a receiving valve 17 through a transformer 16. An additional valve may be used if necessary to receive the higher frequencies through a capacity coupling. At the transmitting end the central and additional conductors are separately earthed through a condenser and resistance in series. The central conductor 2 is fed through a condenser 20 by a valve 21 having a high resistance 22 between the anode and a source of high tension current. The input may alternatively be applied to both conductors 2, 4 by means of two valves in pushpull relationship. Since the high frequencies are propagated mainly through the central conductor it is. advantageous to connect a shunt condenser between the additional and the sheath at each end of the cable.

An overhead suspension system by which a suspended article can be shifted to one of a number of positions within a given area comprises two sets of tracks, the tracks of one set consisting of track members arranged to form longitudinal slots forming front guideways to receive a carriage or carriages mounting the article to be suspended and the tracks of the second set being disposed above and at an angle to those of the first set forming second guideways supporting an auxiliary carriage or carriages from which the first mentioned carriage or carriages can be suspended during transfer from one first guideway to another. The guideways may be formed of pairs of Z- section girders T, Fig. 1, supported by straps from suspension rods secured to the ceiling. Sliders 10 on the guideways support carriages 11 from which an article e.g. a lighting device for use in television studios can be suspended by cables 15. The sliders have rollers 21 on the underside which are a clearance fit between the girder T. In a modification, the guideways are formed of pairs of steel tubes T2, Fig. 5, on the upper surface of which carriages 34 having support rollers 34<SP>1</SP> and guide rollers 33 run. The carriages may be transferred from one guideway to another by means of an auxiliary carriage 40 running on the flanges of a joist 38 which also supports the tubes T2. The carriage 40 has an arm 42 engaging a hole 45 in the carriage 34 so that this can be lifted from the guideway by means of a hand lever 46.

Title: Improvements in or relating to methods of heating ions in a plasma
Inventor: HAMBERGER SYDNEY MAXWELL
IPC: H05H1/16
Filed: 1962-08-24
Abstract: 1,014,382. Thermonuclear apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 19, 1963 [Aug. 24, 1962], No. 32531/62. Heading C6P. The ions of a plasma discharge contained in a magnetic field are heated by the injection into the plasma of a low-frequency electromagnetic oscillation. The plasma is subjected to two high-frequency oscillations which penetrate into the interior and which have values such that the difference frequency is low enough to equal the ion cyclotron frequency. A circular cross-section cavity is subjected to an axially directed D.C. magnetic field and contains low-pressure helium or hydrogen. The electromagnetic waves are directed into the cavity, through a broad-band amplifier from two klystron oscillators. A probe coil measures the rate of charge of the axial magnetic field. The plasma functions as a non- linear impedance and thus produces sum and difference frequencies of the applied oscillations.

Convention dates, Nov. 26, 1936, Dec. 23, 1936, and Jan. 25, 1937. [Class 110 (ii)] In an engine or pump, the piston has one end which is given a rotary motion by means of a crank, causing the piston as a whole to gyrate. Means are provided to secure fluid tightness by mechanism actuated by the crank to give a radially outward force to the piston where it bears against the bore of the working chamber. One form of the invention includes a piston formed of two semicircles joined to form an S-shape. Figs. 2, 3 show a piston 9 which tapers axially in a similar shaped casing. Recesses 14 are connected by passages 15 to the outside atmosphere or to a chamber under pressure higher than that existing in the working chamber. To secure fluid tightness between a piston and its chamber, centrifugal action on a weight acts through rods, or other connecting mechanism to give an outward force component causing the piston to press against the casing bore.
