Abstract: 692,862. Controlling planetary gearing; cams. BRIERLEY ENGINEERING CO., Ltd. April 27, 1951 [April 26, 1950], No. 30375/49. Classes 80 (i), 80 (ii) and 80 (iii). [Also in Group XXXIV] Planetary gearing, in which meshing planet gears 5 are mounted in a rotatable drum 2 and mesh sun gears 4b on driving and driven shafts 4, 4a, is automatically operated by a brake lever 6 co-operating with a flange 3 on the drum 2 in such a way that an intermittent drive is obtained, according as the rotation of the drum is restrained or not. The brake lever 6 is pivotable or rockable on a support 7, has a recess 6a engaging the flange 3, and is acted upon by a spring 8. A pivoted lever 10 engages the lower side of the brake lever 6 and has a cam 10b engaged by a pin 11d on one end of a lever 11a pivoted at 12. The other end of the lever 11a. co-operates through a roll with a cam A driven through worm gearing 13, 14 from the driving shaft 4. The cam A comprises two flat plates of different profile rotatable relative to each other and locked together by a handwheel 15, whereby the effective cam profile can be adjusted. The cam profile shown has one dwell point only, but in practice a plurality of dwell points are employed. The driven shaft 4a is braked by a lever 6x similar to the brake lever 6 and actuated by the cam controlling mechanism so as to prevent the reversal of its direction of rotation on disengagement of the drive. According to the Provisional Specification, the brake lever 6 may be operated manually.

The wheel may be supposed to be cut from that portion of a series of planes radiating from a common axis 5-6 which is included in a cylinder described round that axis. The wheel may be either at right-angles to the axis 5-6, as at A, or oblique to it, as at B. The screen is formed by cutting from such a wheel a non-central portion C or D. In use, the screen is interposed between the body t'o be examined and the floureseent screen or photographic plate in such a position that the axis 5-6 passes through the ray-source. The Specification as open to inspection under Sect. 91 (3) (a) also states that the plates may be parallel to one another, and may be carried, as by inclined hinges, so that they may be adjusted relatively to one another. This subjectmatter does not appear in the Specification as accepted.

Abstract: 451,744. Electric signalling systems. PATIN, A., 13, Woyrschstrasse, Berlin. Nov. 13, 1935, No. 31454. [Class 40 (i)] In a system using a selfbalancing Wheatstone bridge for indicating temperature, the current flow in the diagonal of the bridge which normally contains the responding device is used directly to balance the bridge. As shown in the Figure, variation of the temperature of the unit 12 alters the resistance of the arm 1-3 so that current flows in the diagonal 3-4. This diagonal includes the coil 10 which swings in the field N-S and carries the contactor 5 over resistance 6 to re-establish balance. The pointer shown, also carried by the coil, moves over a suitably graduated scale. A weak return spring 19, which moves the pointer to a zero position if the battery should fail, is used to connect the coil 10 with the diagonal lead 16. The same receiving instrument R may be used with a number of transmitters T if suitable switching is provided.

Abstract: 761,733. Gas turbine plant. GENERAL MOTORS CORPORATION. Nov. 1, 1954, No. 31483/54. Class 110 (3). A gas turbine air intake having surfaces on which ice may be deposited has a suspension of a liquid. Anti-freeze agent in a gas under pressure which is discharged into the air flowing through the intake so as to deposit the anti-freeze agent on these surfaces. A gas turbine engine intake, Fig. 2, has a number of struts 27 between the inner and outer shells 24, 26 and an annular screen 28 extending between the struts. The struts 27, screen 28, and the fixed blading in the first stage or two of the compressor may become encrusted with ice and thus cripple the engine. To prevent this, an anti-icing manifold 30 comprising two annular tubes 31, 32, Figs. 2 and 4, are provided. The tubes 31, 32 are joined by four radial tubes 33 which are supported from the casing 24 by tubes 36 and flanges 37. Some or all of the tubes 36 may be used to supply compressed air, which.may be taken from the compressor of the engine, into the tubes 31, 32. The tubes 31, 32 have a large number of small orifices on the upstream side, through which the compressed air is injected into the compressor intake. The compressed air from the compressor is led through a pipe 52, Fig. 4, to an injector 44 which sucks an alcohol such as ethanol or methanol through the jet 54. The resulting mist of alcohol suspended in air is injected into the duct 23 through the orifices 38 and deposited on the screens 28, struts 27 and the initial blading stages of the compressor. Valves controlling the supply of alcohol and compressed air to the injector 44 may be electrically operated and energized either by manual or automatic means.
