Title: Generation of energy in a gas cycle
IPC: F25B5/00
Filed: 1969-01-07
Abstract: 1,246,161. Gas turbine plant. BABCOCKATLANTIQUE. Jan. 7, 1969 [Jan. 10, 1968], No.1044/69. Heading F1G. [Also in Division F4] In a thermodynamic gas cycle, the temperature of the cycle is lowered at the cold sink by heatexchange with a cold-producing fluid which is derived from a refrigeration cycle using mechanical compression. A gas turbine plant is indicated in Fig. 1 and comprises an air inlet A, a compressor C, a working fluid heater H and a turbine T which drives the compressor also an electric generator G and the compressor F of a refrigerating plant. The air entering the compressor is cooled by flowing across tube coils E 1 , E 2 , E 3  through which refrigerant fluid is flowing. Refrigerant fluid from the compressor F passes to condenser K where it is condensed by flow of cooling water, the liquid then passing through three throttling valves R 1 , R 2 , R 3  in parallel flow, the fluid then passing through three evaporator coils E 1 , E 2 , E 3  where the refrigerant fluid is vaporized by the flow of ambient air to compressor C. The vaporized fluid then passes to three vessels B 1 , B 2 , B 3  from which vapour passes back to the compressor F at three different pressure points. It is stated that the power required to drive the refrigerant compressor F is more than offset by the increased power developed by the turbine as a result of the lower compressor inlet temperature.

Title: A device or apparatus for testing the sparking-plugs of internal-combustion engines
IPC: H01T13/58
Filed: 1920-01-21
Abstract: 162,068. Tucker, J. B. Jan. 21, 1920. Sparking - plugs. - Two gaps, formed between set-screws f and a conductor b are used for indicating the nature of a fault in the ignition circuit. One gap is larger than the plug gap and the other smaller; or, owing to the fact that the plug gap is subjected to a pressure greater than that of the atmosphere, the smaller gap may be the same size as, or slightly larger than the plug gap. The absence of a spark at both gaps indicates an internal short-circuit. The presence of a spark at both gaps shows that the conductive part of the plug is broken, or that the plug gap is too large. Proper working order is indicated by a spark at the smaller gap, but not at the larger. One adjustable gap may be used instead of two gaps; a switch may be used to replace the two leads c, d; or each gap may be connected to a separate pair of terminals in the block a.

Abstract: 299,237. Pehrson, A. P., and Lloyd, F. Jan. 20, 1928. Cores. - A composite destructible core for use in the manufacture, by rolling, drawing, or forging of hollow bars from hollow billets, consists of a helical sheath 4, preferably of strip metal such as copper or copper alloy, enclosing a centre consisting of friable material such as sand, or of a rod 3 of metal such as iron, mild steel, copper, or copper alloy, which has sufficient tensile strength that it will not fracture during withdrawal and will not melt during the reducing operation. The strip to form the sheath is formed of wedge-shape in cross-section to ensure that the convolutions lie closely together. When using a rod centre, the core is removed, after the reducing operation is completed, by pulling, the rod being elongated and thereby reduced in diameter and the convolutions of the sheath falling in slightly to free themselves from the bore of the bar. When using a friable centre this may first be removed by an air blast and the sheath removed by pulling, the convolutions falling in to free themselves from the bore of the bar.

If the hub has a keyway receiving a key mounted on the sleeve to prevent relative rotation of these parts the sides of the keyway may be lined with resilient pads with relatively rigid facings. Arrangements are also described in which the sleeve and the bore in the hub are polygonal, e.g. of square cross-section, the elastic pad segments then being flat members secured to each face of the bore. Each of these segments may be laminated, and divided into sections by grooves extending through all of its layers except the one that is bonded to the hub.
