Filed: 1974-09-06
Abstract: 1471234 Axial-flow compressors UNITED AIRCRAFT CORP 6 Sept 1974 [27 Sept 1973] 39046/74 Heading F1C [Also in Division F2] The compressor section of a turbine type power plant includes an accessory air bleed line 16 having a valve 12 movable between a fully open position and a closed position which permits a small bleed flow. In the arrangement shown the valve has a butterfly disc 28 mounted on a shaft 30 rotatable by actuator 36. The downstream half of disc 28 is undercut relative to housing 32 so that a small bleed flow occurs when the disc is in its closed transverse position, shown. Since the upstream half is thus of larger area, the disc will be urged shut under aerodynamic loading should actuating linkage 52 fail. Actuator 36 includes a spring-loaded piston 50 subject on both sides via ports 56, 58 to the bleed pressure. The pressure above piston 50 tends to urge pilot valve 42 open against the closing action of atmospheric pressure acting on evacuated bellows 40. Thus below a predetermined compressor pressure ratio, butterfly disc 28 is held by spring 48 in the fully open position, the disc moving towards its closed position as the pressure ratio increases. A Venturi 34 may be provided downstream of disc 28. Pilot valve 42 may be replaced by means responsive to power plant speed, compressor bleed temperature or power lever setting. In a modification Fig. 3 (not shown), disc 28 is replaced by an axially slidable member (78) which is prevented from fully closing on its seat by a stop (100).

Abstract: 1,175,439. Rotary fluid-flow meters. FOXBORO CO. Aug.30, 1967 [Sept. 27, 1966], No.39756/67. Heading F1F. A rotary fluid-flow meter includes an annular wheel 17, Fig. 1, which during operation of the meter is both supported and rotated within a chamber 41, Fig. 3, by fluid flowing spirally through the latter from a plurality of oblique nozzles 45 to an outlet channel 40, Fig.6, the fluid being directed to said nozzles from an inlet 36 by way of a plurality of radial channels 21 and an annular chamber 30. Electrical contacts 46, 47 are provided in the peripheral wall 42 of the chamber 41 so that the varying resistance of an electrically-conducting path formed by the fluid in said chamber and a pattern of conductive material (not shown) on the wheel can be detected, whereby the angular velocity of the wheel and hence the rate of flow of fluid can be determined, terminals 46A, 47A for the contacts being located adjacent the outlet end of the channel 40. Most of the components of the meter, including the wheel, may be made of plastics material, the material of which the wheel is made having preferably a density similar to that of the fluid to facilitate the supporting effect of the spiral flow of the latter, Figs. 7 and 8 (not shown). A second embodiment, Fig. 9, is intended for use with a gaseous fluid, the wheel 56 being made of a transparent material and having opaque portions (69, Fig. 10, not shown), thereon so that light issuing from an electric lamp in a transparent member 60 produces a periodicallyvarying signal according to the angular velocity of the wheel, which signal is observed through a recess 65 in a transparent portion or shell 52 of the housing. The fluid enters a chamber 66 containing the wheel through a plurality of oblique apertures 59 in a transparent annular wall 54 that is surrounded by an annular chamber 55, which is connected to an inlet 57 for the fluid. The fluid leaves the chamber 66 through a channel 67. A third embodiment, Figs. 11 and 12 (not shown), differs from the other two mainly in that the wheel (71) has a plurality of oblique vanes (86) thereon so that in response to radial flow of fluid into the associated chamber (76) through an annular passage (78) the wheel is driven in the manner of an impulse-turbine rotor. Rotation of the wheel is observed through a fibre-optic stalk lodged in a passage (94) within an end-wall or piece of the housing.

Abstract: 1488759 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 1 Oct 1975 [20 Dec 1974] 40079/75 Heading H1K In an assembly for supporting stacked semiconductor members, a planar base carrier, having an array of terminal pins which project from one side, supports a planar semi-conducting element which has contact areas connected to both the terminal pins and to terminal areas on a semi-conducting member, supported by the planar semi-conducting element, and which has electrical circuitry. In the embodiment of Figs. 1A, 1B, the base carrier consists of an organic encapsulate 28 enclosing a metallic web 26 and terminal pins 24, which are shaped at one end to engage a conventional printed circuit board (not shown), and which terminate in solder pad joints 32 at the other end. By choosing the web 26 material to have a lower thermal coefficient of expansion (TCE) than the semi-conducting material and the encapsulate 28 material to have a higher TCE than the semiconductor, thermal stresses in the device are minimized. Suitable materials are "Invar" (Registered Trade Mark) for the web 26, and plastics, epoxy, or novolak materials for the encapsulate 28. The supported planar element 30 has conductive vias 38 connected to solder pads 32 by metallization 41, and to terminal areas 42 on integrated circuit devices 36 by conductors 34 formed in openings in the insulating layer 40 on the semi-conducting element 30. In another embodiment, Fig. 2 (not shown), the semi-conducting element includes integrated circuit elements, and has a number of interconnected integrated devices stacked upon it. The base carrier may be an inorganic material, for example Al 2 O 3 , instead of an encapsulated web. In this case, thermal stress effects are minimized by supporting the semi-conducting element on elongate flexible terminal pins, Fig. 3 (not shown).

Polyester resins are prepared by reacting a diepoxide which contains at least two 2,3- epoxyisobutyl ether groups per molecule with a polycarboxyl compound. The polyepoxides may be prepared by reacting a polyhydric phenol with 2-methylepichlorohydrin in the presence of a basic compound. Mixed polyesters may also be prepared by including a polyhydric alcohol. Under conditions of reaction the diepoxide behaves as a glcyol, the tertiary hydroxyl groups obtained by hydrolysis of the epoxy groups are substantially unreactive. By employing an excess of the diepoxide it is possible to prepare higher M.W. epoxy resins, having polyislic linkages which may be cross-linked by conventional hardeners. By additionally using a fatty acid in the condensation reactions resins similar to oil-modified alkyds are obtained. By using unsaturated polycarboxylic acids, unsaturated polyester resins are prepared which may be blended and copolymerized with ethylinically unsaturated monomers. Reference has been directed by the Comptroller to Specification 1,104,494.
