Title: Igniters for gas turbine engines
Inventor: GOREHAM KENNETH ALBERT
IPC: H01T13/52
Filed: 1984-09-28
Abstract: The igniter (40) has a cavity (47) formed by a tubular semiconductive pellet (50) which is contacted by an electrode (52) at one end, and by the outer shell (43) of the igniter at its other end, forming the other electrode. The cavity (47) opens through an aperture (48) in the shell (43) at the operative tip (41) of the igniter, such that, when the electrodes (52 and 43) are energised, discharge is produced in the cavity (47) and a plasma jet (60) is projected through the aperture. The tip (41) of the igniter is displaced from the inside surface (24) of the wall (21) of the combustion chamber away from the combustion chamber such that the tip of the igniter is located in a cooler region of the engine. The semiconductive pellet may be omitted and a high voltage used to produce the plasma jet. <IMAGE>

Title: Railway crane
Inventor: BRORKENS JOHANN
IPC: B61F5/24
Filed: 1986-12-03
Abstract: Railway cranes (see Fig. 1) having an undercarriage (2) carried by two bogies and an upper carriage (3) pivotably mounted thereon with a jib (4) are equipped, for security against derailing and optimisation of the loading of the upper structure, with slide blocks (12) allocated each to one bogie side, through which the undercarriage (2) is supported on the bogies (1) after a predetermined clearance is taken up. In order to minimise the wheel load or wheel assembly load increases occurring on displacements of the centre of gravity of the crane, for example by jib movements or loadings, and thus to increase the load capacity of the crane, the slide blocks (12) are made displaceable in the vertical direction and securable, singly or plurally. Displacement may be by means of hydraulic cylinder drive mechanisms or mechanical spindle drive mechanisms (13) connected to a control system such that on displacement of the centre of gravity of the crane equal loading of several slide blocks or slide block groups and thus of the corresponding wheels or wheel assemblies (6) is retained. For normal transport of the crane the blocks (12) can be locked in position by engagement of pins 14 in recesses in the blocks.

Patent GB-2205615-A (GB)
Title: A water powered motor
Inventor: BASSETT DAVID
IPC: F03B7/00
Filed: 1987-06-06
Abstract: The motor has a casing 6 defining a passageway extending between inlet 11 and outlet 12 apertures, and a rotor 1 mounted to rotate within the passageway about a fixed axis. The radial distance between the rotor axis and adjacent walls of the passageway is greater on one side of the rotor axis than the other, and a plurality of vanes 9 are movably mounted on the rotor. The vanes assume a position relative to the rotor such that the passageway is always obstructed by the vanes and rotor which extend across the full width of the passageway between the adjacent walls. As the rotor is offset towards one side of the passageway, and therefore the surface area presented by the vanes to water flowing from the inlet to the outlet is greater on one side of the rotor than the other, a torque is applied to the rotor. In an alternative arrangement the vanes are instead pivoted to the rotor and are arcuate (Figs. 7 to 10). <IMAGE>
