Title: Clearance control in gas turbine engines
Inventor: PLEMMONS LARRY WAYNE
IPC: F01D11/18
Filed: 1991-05-17
Abstract: A gas turbine engine stator 48 and method are disclosed which are effective for controlling non-axisymmetric radial running clearance variations between a stator flowpath surface 76 and rotor blade tips 74. A coating of higher or lower thermal conductivity than that of the stator is disposed along the circumference of the stator in such a way as to control thermally induced non-axisymmetric distortion and thereby control non-axisymmetric radial running clearance. In preferred embodiments of the invention, a high thermal conductivity coating eg of nickel may be applied to an annular flange 50 for reducing temperature gradients therein. In another embodiment of the present invention, low thermal conductivity coatings eg of ceramics may be applied to a stator to preferentially insulate parts of the stator for reducing thermal distortion. <IMAGE>

Title: Improvements relating to fodder distribution devices
Inventor: MARRIAGE ROBERT WALLIS
IPC: A01F29/00
Filed: 1991-09-09
Abstract: A tub (1) supports a large round bale (19). Rotation of a drum (3) (provided with cutting blades, not shown) feeds cut portions of the bale over the top of the drum and out through a side wall (5). A roller (6) acts as a deflector to limit the amount of cut fodder which tends to be thrown upwards. If the torque of the drum (3) increases due to an excess amount of fodder being fed, a lever (14) rotates and operates a spool valve (17) which controls operation of a piston and cylinder device (18). This in turn controls the position of an arm (9) carrying the roller (6) and brings the roller down on to the bale (19), thus pushing the bale away from the drum (3). Once the pressure on the drum (3) is relieved, the spool valve (17) closes again and the roller (6) returns to its normal position at a controlled slow speed so that the bale is reintroduced slowly to the drum.
Patent GB-2251279-A (GB)
Title: Vacuum booster
Inventor: SHINOHARA TAKAYOSHI
IPC: B60T13/563
Filed: 1991-10-28
Abstract: A vacuum booster shell 1 is attached to a vehicle body D by four connecting bolts 35 which pass through a pedestal 32 formed on the rear wall of the shell 1. These bolts 35 are arranged in a rectangle 33. The peripheral wall 32b of the pedestal comprises a pair of shorter side walls 34S parallel to the shorter sides S of the rectangle 33, a pair of longer side walls 34L each bent so as to be spaced gradually farther from the corresponding longer sides L of the rectangle, proceeding from an end to a central portion, and four corner walls 34C each arcuate and connecting the adjacent shorter and longer side walls. Thus, the intermediate portion of the longer side wall 34L of the pedestal 32 is increased in rigidity, so that an increased load can be imposed on it, thereby ensuring a moderation of the stress concentration around the corners. This leads to an improvement in durability of the booster shell. <IMAGE>

Filed: 1992-12-18
Abstract: A waterboiler comprises 2 kW and 1 kW heating elements (11, 12 respectively) that together heat the water (2) to about 96 0 G, as sensed by a thermistor (14), whereupon the 2 kW element (11) cuts out and the water (2) is further heated to, and maintained at, water boiling point by the 1 kW element (12). The arrangement lessens the problems of cavitation noise and element scaling associated with prior waterboilers. In an alternative embodiment, the output of a single heating element is modulated by using a transformer to reduce the voltage in put. A water inlet has a solenoid valve (8) controlled by a reed switch (9) actuated by a magnetic float (9'). Another reed switch (10)/magnetic float (10') ensure that the healing elements (11, 12) cannot be energised until they are immersed. <IMAGE>

Title: Detecting diamond inclusions in kimberlite particles
Inventor: TAPPER ULF ANDERS STAFFAN
IPC: G01N23/08
Filed: 1995-01-06
Abstract: One aspect of the invention concerns a method of classifying particles according to their composition. In the method the particles (12) are irradiated with electromagnetic radiation, typically X-radiation, at respective first and second energy levels. First and second values are derived which are representative of the attenuation of the radiation by each particle. A third value is then derived as the difference between or ratio of the first and second values, and the particles are classified according to whether the third value is indicative of the presence in the particles of a particular substance. In one application of the method it can be used to classify diamondiferous kimberlite into a fraction consisting of kimberlite particles containing diamond inclusions and a fraction consisting of barren kimberlite particles. A rotatable gantry (22) carries the source (24) and the spaced detectors (26) to allow tomograms to be taken by a CAT or laminographic technique. <IMAGE>

Title: Hydraulic circuit containing a filter with automatic back flushing
Inventor: CLAPHAM WILLIAM STEPHEN
IPC: F15B21/041
Filed: 1996-05-10
Abstract: A hydraulic circuit has a fluid pressure inlet line 1; a fluid pressure delivery line 2; and a filter unit FU interposed between the two. Normal flow is from line M1 through valve A, through lines M2 and M3, through filter FU and out through valve B via line M4. The start up condition shown in fig. 1 has spring urged valves C and B closed. The circuit incorporates an automatic back flushing facility in which an initial flow [ie from a static condition], must pass through back flushing line BF1. [Although valve A is open flow cannot be in the normal direction because valves B and C are closed]. From BF1 flow is through the filter FU in the back direction and thence via M3 and line BF2 to waste via BF3. Behind valve A at 6 is a throttling arrangement O. Fluid also passes to this arrangement via line BP1. Pressure thus caused behind valve A causes it to gradually close in the direction indicated. Once fully closed the pressure also causes valves B and C to open and valve D to close thus shutting off the back flush path and opening the normal path. In its fully closed condition valve A closes off the beginning of the back flush path but leaves open the normal path. Thus the system is always automatically back flushed before normal operation commences. It can be deliberately shut down at a chosen time by stop valve MV. Thus upon re-opening this valve the back flushing sequence will start.

IPC: E21B33/00
Filed: 1996-10-25
Abstract: A mudline casing hanger system is set forth which is particularly intended for use in installing multiple casings from a jack-up rig at the surface. The rig is used to drill the well and instal multiple casings which are arranged concentric one within the other. When the casing strings have been installed all the weight of the casings are transferred by the casing hanger system to the outer conductor pipe so all the weight is supported at the mudline. The several casing strings above the mudline are disconnected to enable the well to be shut in so that the rig can be subsequently moved. Later, a different platform is typically installed and the casing strings are reestablished from the mudline to the platform above the water.
