Abstract: 796,040. Radar. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 26, 1955 [Dec. 21, 1954], No. 36873/54. Drawings to Specification. Class 40 (7). In a continuous-wave Doppler speed indicator, carried in an aircraft, frequency pulling of the transmitter is prevented by the insertion of an attenuator in the transmitting waveguide channel. The attenuator is direction sensitive, employs the Faraday effect, and transmits signals to the aerial while attenuating those back from the aerial to the transmitter. The signals so attenuated are stated to be those received at the aerial after reflection back from the aircraft frame, as the latter is in a vibrating state the reflected waves are modulated and tend to disturb the transmitted frequency if received. Specifications 638,167 and 646,353 are referred to.

Abstract: 1,067,335. Arc furnace control. ALLEGHENY LUDLUM STEEL CORPORATION. Sept. 2, 1965 [Sept. 15, 1964], No. 37619/65. Heading H5H. [Also in Division G3] A consumable electrode arc furnace, has means for sensing arc current and voltage which in the absence of both quantities for example on failure of the supply, causes the electrodes to move away from the melt a determined amount. When, after starting, the arc has reached stable conditions, a relay SA is energized through a manual switch 104. On cessation of the supply, voltage and current sensing relays VS, CS are de-energized, energizing relays V, C, hence lines 98, 100 are shunted through contacts C-3, V-4, SA-4, TD-1, thus energizing a raise circuit 96. A time delay relay TD is de-energized at the same time through contacts C-1, V-2, opening contacts TD-1 after an interval thus removing the shunt from lines 98, 100. The furnace may be alternatively controlled by an arc voltage circuit 52, 54 or a voltage discontinuity circuit 88, 90, 92 which causes pulses from a generator 57 to move the electrodes through a positional control arrangement in an approaching direction only.

Abstract: 327,118. Mraz, J. L. Dec. 22, 1928. Sleeve couplings. - The adjacent ends of two wires, rods, &c., 5, 5, Fig. 2, such as electric conductors, or tension wires of aeroplanes, are connected by inserting said ends into a metal sleeve 1, which is of circular cross-section and is provided with a bore 2 of slightly larger diameter than the wires, and then compressing the sleeve by means of the dies 6, 6, Fig. 3, which are advanced step by step along the entire length of the sleeve. Each die is constituted by a block provided with a straight groove 7, Fig. 4, in the form of an arc of a size slightly less than a semi-circle and of a radius slightly less than that of the tube or sleeve 1, so that when pressure is first applied to the tube 1 by the dieedges 8 the said tube will be compressed in the direction of the line x, Fig. 5, and forced against the enclosed wire at diametrically opposite points. Continued pressure will cause compression of the tube in a direction at right angles to the first compression so that the tube is forced into contact with the whole circumference of the wire, Fig. 6, and longitudinal ribs 9 are formed thereon. The middle of the sleeve 1 is indented at opposite sides to form abutments 4 for the ends of the wires while the ends 3 thereof are flared to facilitate entry and permit bending of the wires. In order to increase the tensile strength of the joint, the sleeve and wires may be bent during the compressing operation by forming one of the dies with a hump 15, Fig. 8, and the other die with two humps 16. The invention is also applicable to the connecting of overlapping wires and to the jointing of a wire to a hook, bolt, &c. The wires may be roughened prior to jointing.
