Abstract: 378,871. Spray carburetters. CARBURATORI MEMINI SOC. ANON. ITALIANA, 16, Via Poliziano, Milan, Italy. April 14, 1931, No. 10518/32. Addition to and divided on 372,913, under which a Specification was laid open to inspection under Sect. 91 of the Acts, April 15, 1931. [Class 7 (iii).] In a carburetter for aircraft engines in which automatic control means are provided by which the fuel supply to the float chamber is cut off in the inverted position of the carburetter and the fuel supplied direct to the atomizing-jet, instead of having separate supply pipes for the float chamber and the atomizing-jet as described in the parent Specification, a single fuel supply pipe is provided which supplies the float chamber under normal conditions. The fuel is fed through passages 9a, 35 to a chamber 37 in which is a valve 23a which, according to the position of the aircraft, closes either the entrance of the fuel into a duct 10a leading to the float chamber 5a, or the entrance of fuel into a duct 19a from which it falls directly into a duct 42 leading to the nozzle 4a. Flooding of the float chamber during inverted running is prevented since the fuel falls directly from the duct 19a into the duct 42. In the latter case, a needle valve may control the flow of fuel in the duct 19a.

Filed: 1957-04-02
Abstract: 891,951. Hydraulic brakes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 26, 1958 [April 2, 1957], No. 10728/57. Class 103 (1). In a.braking system having a mechanically applied brake, means is provided whereby reaction from this brake will produce hydraulic pressure to assist this braking by the operation of hydraulic braking means so that when a driven or moving element, e.g. a brake disc 1, is moving in one direction the mechanically operable braking means will operate a piston in a stationary hydraulic cylinder to pressurize the hydraulic braking system and when the driven or moving element is moving in the reverse direction the mechanically operable braking means will move a second piston in a second stationary cylinder to apply hydraulic pressure by way of the first cylinder to the hydraulic braking system. In the embodiment illustrated, a brake disc 1 has a brake band 2 arranged about its periphery and adapted to be applied by means of a pedal operated cable 4. Upon gripping the disc 1, the brake band 2 is rotated a small amount by the rotary movement of the brake disc so that a roller 7, mounted on the band, actuates one or other of two rigidly mounted cylinders 12, 13 to create hydraulic pressure in the line connected to port 15 leading to the hydraulic brake (not shown) which applies axial braking effort to the brake disc. Cylinder 13 is connected to cylinder 12 by means of pipe connection 20 so that pressure created in cylinder 13 is transmitted to cylinder 12 and thence via port 15 to the fluid-pressure-operated brake. Port 19 at the inner end of cylinder 13 is connected to a header tank (not shown) for replenishment of the system. Reference has been directed by the Comptroller to Specification 809,075.

Filed: 1947-04-23
Abstract: 656,547. Resilient mountings. DOBBIE McINNES, Ltd. April 23, 1947, No. 10824. [Class 108 (iii) ] An antivibration mounting for an object comprises two longitudinally inextensible and fixedly located pendulums, one 23, Fig. 5, upright, and the other 22 inverted, and link means 24 between deflectable parts of the pendulums and adapted to carry the object to be mounted. The supports for fixedly locating the unmovable ends of the pendulums 22, 23 are omitted from Fig. 5. In the construction shown in Fig. 4. the link means comprises a further pair of pendulums 23a, 22a, upright and inverted respectively, between which a frame 37 for carrying the object to be supported, is connected. A frame 32 is fixed at one corner, to an inverted pendulum 22 formed by the upper end of a flexible member secured at its lower end to brackets 33 on a base 31. The frame 32 is also fixed, at its diagonally opposite corner to the lower end of a pendulum 23 formed by a similar flexible member whose upper end is secured at 34 to elongated brackets on the  base. The frame 32, which is thus able to oscillate in its own plane, carries upper and lower arms a, b projecting at right angles to and in opposite directions from its plane, which arms carry respectively the upper and lower ends 36, 35 of flexible members comprising the pendulums 23a, 22a and whose other ends are connected to the frame 37. This latter can thus oscillate through the plane of the frame 32, and has universal movement. The resilient arms, which are made as long aspossible, may comprise a single elastic strip, or two strips in cruciform and pinned together at their mid points, or two strips arranged in V-shape. The resilient arm 23, Fig. 4, may be arranged to touch, the rounded edge of the supported frame when large deflections occur, so   as to increase the damping effect, and pivoted arms may be used instead of resilient ones. A weight 38 may be attached to either or both frames to increase 'the period of vibration of the system, but if' the inner frame alone is weighted for this purpose, a balance weight may be needed for the outer frame. The periods of vibrations of the inner and outer frame should be kept as different as possible.
