Title: Improvements in and relating to overhead electric conductors for vehicles
IPC: B60M1/20
Filed: 1931-01-22
Abstract: 371,858. Suspending cables. AKT.- GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Jan. 22, 1931, No. 2189. Convention date, Jan. 22, 1930. [Class 36.] To enable an omnibus with trolley pole current collectors to run on a tramway network, a second negative conductor is mounted beside, and as much above, the tramway positive conductor as will avoid short-circuit due to the rise of the current collector under pressure of the bow. Fig. 2 shows associated positive and negative conductors a, b respectively, suspended from a span wire g and arranged for traffic in both directions. Hangers c carry the conductors a, b, and are joined by a bridge e to form a double hanger. The hangers c are supported with respect to the span wire g by arms d. In the construction of Fig. 6, armless hangers c are connected by a bridge e and are suspended from arms l, m, which are slidably mounted on a bracket n. To allow vertical positioning of the hanger bolts f, the suspension members o are provided which are adjustable on the arms l, m. A modified construction provides for a crossing of two pairs of conductors. The trolley collector runs off the negative conductor on to a lignum vitµ rib on which it runs downwards a distance equal to the difference in height between the positive and negative conductors, and from which it runs back again to the negative conductor. Running-on and off ribs are provided.

Title: Directional antenna arrays
IPC: G01S3/08
Filed: 1944-02-07
Abstract: 592,576. Radio direction-finding. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1944, No. 2274. Convention date, March 12, 1942. [Class 40 (v)] In a dipole Adcock aerial array 1, 2, 3, 4, Fig. 3, for direction-finding, a flat horizontal conductive structure, Fig. 5, incorporating an electrostatic screen 11 for shielding the horizontal leads, is provided for the purpose of reducing errors due to any horizontally-polarized component of radiation and to the high-antenna effect. The high-frequency self-inductance of the'simple screen 11 prevents it from being an equipotential surface, and thus impairs its effectiveness, but this defect is reduced by adding conductive arms R and preferably arms Ra, Fig. 5. Further, conductors S extend beyond the dipoles 1, 2 and 3, 4 and reflect radiation so as to diminish the horizontal electric field near the dipoles. Error arising from unequal coupling, to the shield 11 or earth, of the upper and lower halves of the dipoles is balanced out, Fig. 7 (not shown), by the extension S. Two crossed pairs of Adcock aerials may be provided with a common structure, Fig. 9 (not shown), analogous to that shown in Fig. 5, or a solid horizontal sheet of metal may be used. Error due to the highantenna effect, and arising from currents which flow from the dipoles through the down leads 8, 9 in parallel, but affect the indicator 10 as a result of accidental asymmetry in the coupling, is reduced by the structure R, S, Ra, Fig. 5, in virtue of a diminution of the capacity between the dipoles and earth. The high-antenna effect is further reduced by the isolation of the dipoles 1, 2 and 3, 4 from the horizontal lines 5, 6 by means of a coupling transformer which may have an earthed screen between its windings, or preferably, Fig. 10, by means of transformers and of valves connected as push-pull cathode-followers. The horizontal conductive structure may be constructed as a unit, Fig. 14, for application to a pair of crossed Adcock aerial arrays and may comprise five circles and four rods welded together as shown.

Abstract: 469,455. Cathode ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BRETT, G. F. Jan. 24, 1936, No. 2354. [Class 39 (i)] Cathode-ray tubes for low voltages such as 150-350 volts and with a short length of cathode-ray such as 4 inches are provided with a simple cylindrical envelope E enclosing an indicating screen S which is transverse to and offset from the axis of the electron gun G. The screen is preferably parallel to this axis and to the axis of the envelope E, and can be viewed directly through the side of the envelope or through a lens L with its axis perpendicular to the screen. The screen S is a metal plate coated with fluorescent material and the ray is given a steady deflection towards the screen in addition to the usual deflections at right angles to trace a picture on the screen. The steady deflection may be magnetic and the usual deflections electrostatic, or all deflections may be produced by mutually perpendicular pairs of coils. The gun G may be as described in Specification 469,418. The deflecting wave forms may be modified to avoid trapezium-distortion due to the position of the screen S.
