Title: Circular knitting machine
Inventor: SANGIACOMO FULVIO
IPC: D04B9/36
Filed: 1985-07-25
Abstract: A circular knitting machine, e.g. a four-feed machine for inlaid patterned hose, has electronic programmed control of the cylinder drive whereby signals indicative of the angular position of the cylinder are derived during both rotary and reciprocatory knitting and are used to influence electronic needle selection units, there being as many such units as yarn feeds and the units being arranged (e.g. intermediate the feeds) so as to be associated with different feeds in the two directions of reciprocation. The selection units may each be divided into two sections 10a, 20a at different levels and acting on respective jacks 14, 24, one section selecting needles for knitting and the other needles for inlaying. A yarn-cutting mechanism which is also under electronic programme control is further disclosed. <IMAGE>

Title: Method of producing metallic thin film coil
Inventor: WATANABE SHIGERU
IPC: H05K1/16
Filed: 1986-12-15
Abstract: On a surface of an insulated substrate 20, an insulating frame 50 in the shape of a spiral is formed and a metallic film having a thickness smaller than the height of the frame is vapor deposited simultaneously on a bottom 54 and a top 52 of the frame to form a first coil 41 on the bottom and a second coil 42 on the top. By connecting these coils in series, the number of turns are doubled, and by connecting them in parallel, electric resistance is reduced by half, so a limited space can be used effectively. The frame 50 is produced by etching a 4-micron layer 51 of photoresist. The undercut portions at 53 ensure the separation of the two coils which are formed by a 2-micron layer of copper, gold, silver or aluminium. The whole surface is then coated with an insulating protective layer. The coils may be circular or square. <IMAGE>

Title: Gas turbine engine
Inventor: JUBB ALBERT
IPC: F02C6/20
Filed: 1986-12-19
Abstract: A gas turbine engine (e.g. for use in a land vehicle) (10) capable of operating in two modes comprising in flow series a low pressure compressor (13), a high pressure compressor (15) a heat exchanger (16), combustion equipment (17), a high pressure turbine (18), and a free power turbine (20). In the first mode of engine operation, the efflux from the power turbine (20) is directed through the heat exchanger (16) to be in heat exchange relationship with the high pressure compressor (15) efflux. However in the second mode of operation when a power boost is required (e.g. for powering ancillary equipment), the heat exchanger (16) is by-passed by the free power turbine (20) efflux and the efflux is ducted directly to a low pressure compressor (24) which drives the low pressure compressor (13) to boost the air delivered to the high pressure compressor (15).   <IMAGE>
