Abstract: 1,225,759. Gas turbine type gas generators. C.A.V. Ltd. Sept.24, 1968 [Oct.5, 1967], No.45458/67. Heading F1G. The invention relates to a hot gas generator which comprises a first compressor, a second compressor, a combustion chamber and a turbine, the first compressor supplying an air/fuel mixture to a burner disposed within the combustion chamber, the second compressor supplying dilution fluid to the combustion chamber, combustion gases from the combustion chamber being directed on to the turbine which is connected to drive the first and second compressors, exhaust gases from the turbine passing to a point of use. In accordance with the invention a portion of the exhaust gases from the turbine are passed back to the inlet of the first compressor thereby reducing the combustion temperature. In the plant shown, the first compressor rotor 16 and the second compressor rotor 17 are mounted at one end of a shaft 11 and the turbine rotor 12 is mounted at the other end of the shaft. An air and fuel mixture is supplied to the inlet 22 of the first compressor 16 and the mixture is delivered by the compressor through duct 31 to the burner 29 mounted within the combustion chamber 24. The second compressor 17 supplies dilution air through duct 29a to the combustion chamber. Combustion gases pass to the turbine 12 which drives the two compressors, the exhaust gases then passing to a point of use. A portion of the turbine exhaust gases are passed through line 35 to the inlet 22 of the first compressor 16, the flow being controllable by valve 36.

Abstract: 1,226,941. Aerials. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 6 May, 1968 [23 Feb., 1967], No. 8642/67. Heading H4A. A microwave aerial comprises an insulating base-board 1 on the rear face of which a conductor 2 is formed by a printed circuit technique so that it follows an undulating path about its longitudinal axis 5, Fig. 2. The said path is symmetrical about its mid axis 6, with mirror symmetry. A U-shaped conducting channel 3, Fig. 3, having its edges 4 abutting against the rear face of the base-board 1 houses the conductor 2 and extends parallel to the longitudinal axis 5 thereof. The said conductor is fed at its centre and, as described, the inner conductor 9 of a coaxial line is connected to it, passing through an insulating bushing 8 held in a central metal block 7 fitted inside the channel 3. The outer conductor 10 of the coaxial line is secured to the outside of the channel 3. Radiation from the aerial is outwardly from the front face of the base-board 1, and it is stated that the direction of propagation remains constant over a band of frequencies. The aerial may be used in combination with a part-cylindrical reflector for which it acts as the feed. A plurality of such conductors 2, Fig. 5, may be formed upon a common base-board 1 with their longitudinal axes parallel, to constitute an array. A single sheet of conductive material may be bent to provide channels 3 over the conductors 2, and between each pair of channels may be provided a quarter-wave choke 11. The spaces 12 on the reverse side of the said sheet may have a suitable rigid filling, such as a foamed plastics material. An insulating coverplate 13 is provided, through which the feeders to the centres of the conductors are taken. In a stripline feed system for an array, the exposed surface of the insulating cover-plate (13), Fig. 8 (not shown), is provided with a conductive coating and forms one ground plane of the feed system. Another ground plane (16) is provided which is spaced from the plate (13), and between them is an insulating sheet (14) upon which a pattern of feed conductors (19), Fig. 9 (not shown), is formed by a printed circuit technique. The outer conductors (10) of the coaxial lines to the centres of the radiating elements are connected to the ground planes, and their inner conductors (9) to the feed conductors (19). By means of an arrangement comprising hybrid rings and feeders of appropriate dimensions the radiating elements are fed with powers in controlled phase and amplitude relationships. A Babinet equivalent for the undulating wire aerial shown in Fig. 2 is also described. In this an undulating slot (2<SP>1</SP>), Fig. 4 (not shown), in a conductor has rotational symmetry about its mid-point.

A wheel disc cover 1 comprises a plurality of fixing members 3 equi-angularly spaced around its inboard surface. The members 3 are of plastics material having two protrusions 5 and 6, and are attached to the cover 1 by projections 7 which extend through respective apertures to the outboard face of the cover and are hot compressed. Alternatively, the fixing members may be attached to the cover by rivets, in which case the rivet heads form the protrusions 8 and 9. In a further embodiment the fixing members are of the form shown in Fig. 7 where a flat plate 17 has one longitudinal edge rolled back to form a central cylindrical portion 18 and two extreme cylindrical portions 20, 21 of larger diameter than 18. In a more resilient form of such a fixing member (Fig. 10, not shown), the plate is initially of U-cross-section, and the flat part of this, after the cylindrical portions have been formed in the other part, is attached to the wheel disc cover.

Abstract: 1,238,892. Valves. PULLMAN Inc. 22 Oct., 1968 [24 Oct., 1967], No. 50183/68. Heading F2V. In a valve having one inlet 2 and two outlets 4 and 5, closure of either one of the two outlets is effected by means of a ball 17, the ball being rotatable about, and longitudinally movable along, a ball shaft 15 which is secured to a manually rotatable valve shaft 17. The ballmounting arrangement in conjunction with the disposition in relation to the shaft 7 of each seat 21, serves to ensure that initial contact between the ball and a seat occurs at a point on the seat, which point is disposed between 45 and 315 degrees from a reference point located on the seat and disposed in closest proximity to the valve shaft 7, the location of such initial contact in turn ensuring that the ball is free to rotate about, and/or move longitudinally along shaft 15 in order to minimize localized wear of the seat and permanent adherence to either the seat or the ball of particulate foreign matter. The valve shaft operating lever (8, Fig. 3, not shown), is releasably lockable in either of its two positions corresponding to complete closure of either one of the two outlets. Each seat may be constituted by valve flanges 20 or, alternatively by a plurality of rings which are arranged in abutting or spaced relationship within the outlets and whose diameter decreases in the direction of fluid flow.
