Title: Structure for Extracting Energy from A Moving Mass of Water
IPC: F03B17/06
Filed: 1980-07-29
Abstract: A structure is anchored in a flow of water to extract energy therefrom, the water flowing into a main channel 1 and two outside channels X, Y. The main channel 1 leads into two or four small channels 2a-2d through sluices 5a-5d, only one of these being open at one time, and it's closing opening the next in line. Flow in a small channel closes the respective exit valve 3a-3d thereof and which is placed at such an angle that shock waves travel to compress air in an air chamber (not shown) to do useful work, to close the sluice and to assist the outside channels to evacuate water. By this means a rapid cycle is maintained-the power is not dissipated by turgid water. The compressed air operates an air motor linked to a fly-wheel driving a generator producing electricity. <IMAGE>

Title: Annular gap gas washers
IPC: B01D47/10
Filed: 1980-12-18
Abstract: A gas washer, for example, for separating solid particles from the exhaust gases from blast furnaces or converters comprises a truncated conical housing 5, a truncated conical displacement body 7 which is mounted co-axially in the housing 5 with an annular gap between the displacement body and the housing, inlet ducting 6 for conducting the gas to be washed through the annular gap 12 and a sprayer, which is not shown, for injecting a spray of washing water into the gas before it flows through the annular gap 12, and is characterised in that the angle of conicity of the displacement body 7 differs from the angle of conicity of the housing 5 so that the annular gap 12 tapers in radial width from its inlet end to its outlet end. As a result, an unstable flow condition through the annular gap, which previously existed and tended to cause the displacement body 7 to vibrate, no longer occurs over a wide range of gas flows. <IMAGE>

Title: Improvements in and relating to pipe connectors
IPC: F16L37/62
Filed: 1981-06-02
Abstract: The present invention relates to a pipe connector particularly but not exclusively for use in connecting pipe sections of a pipe string for use in drilling. The pipe connector comprises a pin member (1) having a generally frusto- conical outer peripheral surface (5) and a box member (3) having a corresponding generally frusto-conical inner peripheral surface (6), the members being in use telescoped together with the peripheral surfaces overlying one another. Intermediate end surface portions (17 to 20), the peripheral surfaces (5, 6) are provided with annular grooves (7) and projections (10) which are interengageable to axially lock the members together. The crests of the projections and roots of the grooves lie on generally frusto-conical surfaces having the same conicity as the frusto-conical surfaces of the peripheral surfaces, and the end surface portions (17, 18) of the box member lie intermediate the frusto- conical surfaces of the roots of the grooves and the peripheral surface thereof or on the frusto-conical surface of the peripheral surface thereof, and the end surface portions (19, 20) of the pin member lie intermediate the frusto-conical surfaces of the peripheral surface and the crests of the projections or on the frusto-conical surface of the crests of the projections. The end surface portions are thus relatively dimensioned to be a force fit one on the other to create stressed bands at the ends of the overlapped surfaces of the members and to minimise the extent to which these surfaces of the box member have to expand or of the pin member have to contract to disengage the members. <IMAGE>
