Title: Fuel pump for engine
Inventor: WALL ROBIN CHRISTOPHER
IPC: F02M59/30
Filed: 1996-09-10
Abstract: A fuel pump comprises a primary pumping plunger 16 reciprocable within a first bore to pressurize fluid within a primary pumping chamber, and a secondary pumping plunger 28 reciprocable within a second bore under the influence of the fluid pressure within the primary pumping chamber to pressurize fuel within a secondary pumping chamber 32. Fluid is supplied to the first bore through an inlet port 18, the port being closed by the primary plunger 16 as it moves to force fluid to drive the secondary plunger 28 against the action of a spring 34. Delivery is ended when fluid spills from the first bore through a blind drilling in the plunger 16, an inclined groove in the surface of the plunger 16, and a spill port 24. Fuel, which may be di methyl ether, is supplied to the secondary bore through a non-return valve (58, Fig.2) connected to a supply system incorporating a purge arrangement.

Title: Display device
Inventor: COMER PAUL
IPC: G09F15/00
Filed: 1997-06-12
Abstract: A display device comprised a backing board 2 for securement to a wall by, for example, four screws 4 and a frame 1 surrounding the backing board 2. Locking rods 6 are movable in cavities 7 which are formed by a first limb 7a in the backing board and a second limb 7b in the frame; in the position shown the rods lock the frame and backing board together, but if the rods are moved to lie entirely within the backing board then the frame can be removed from the backing board. The rods are concealed within the device and movement is by magnetic attraction to an external magnet. Displayed material held in position can thus be removed when frame 1 is removed from backing board 2. The frame may be hinged to the backing board along one side. Secondary locking members ( 11, 12, Figure 4 ), may be provided for each of the primary locking rods 6.

Title: Downhole activation circuit valve
Inventor: HUBER KLAUS B
IPC: E21B43/1185
Filed: 1997-11-28
Abstract: A downhole valve 10 for use within a string of tools in a well for controlling a hydraulic activation circuit has a housing 60,62 with an inlet 90 and an outlet 92, defining a portion of the circuit extending between the inlet and the outlet. A moveable piston 68 within the housing in a first position (as shown) provides communication (via passages 94,96,98,100,102) between uphole and downhole parts of the circuit, and in a second position isolates the uphole and downhole parts of the circuit (when passage 98 moves below seal 78). A frangible member 84 is constructed to support, in an intact condition, the piston 68 in one of these two positions against a biasing force, and in a shattered condition enables the piston to move in response to the biasing force to the other position. A detonating member 104 extending through the frangible member 84 propagates a detonation wave to shatter the frangible member when desired, closing the valve. The valve is capable of closing very rapidly, and is particularly useful for isolating an uphole part of a hydraulic activation circuit when used with detonatable tools that can damage hydraulic control lines upon detonation, such as perforating guns. In other embodiments the valve is used to enable hydraulic activation of a tool when opened by a detonation. Methods of altering a hydraulic activation circuit within a string of tools in a well are also disclosed.

Title: Plugging a conduit by freezing
Inventor: RICHARDSON ROBERT NEIL
IPC: F16L55/103
Filed: 1998-11-12
Abstract: A section 1 of a conduit 1,2 has a non-circular geometry so that it can be cooled more easily to freeze its contents to form an inline plug. This design overcomes the limitation on conduit size since it minimizes the distance between the core of the fluid contained in the conduit and the cooled outer surface. Preferably, the conduit maintains a constant cross-section flow area which does not impede the flow during normal operation. The ends 3 of the conduit may be flanged, screw-threaded or prepared for welding. The conduit may be cooled by a jacket (6, figure 7) containing coolant or by an integral network of tubes or passages (9-11, figure 8) through which a coolant is circulated.

Title: Method of micromachining aerofoil components
Inventor: DUFFIN JASON
IPC: B23K26/08
Filed: 1999-01-06
Abstract: The method is suitable for the micromachining of accurately aligned holes in the aerofoil surface of a component such as a jet engine turbine blade or vane which comprises a ground anchorage portion (12) and a cast aerofoil portion (10). The method uses a laser machining apparatus which is preprogrammed to machine holes in the aerofoil surface (10) when that surface (10) is in a predefined reference position and orientation in the apparatus. Initially the component is mounted in the laser machining apparatus by means of its anchorage portion (12). At least one probe (30, 32, 34, 36) is then moved over the surface of the cast aerofoil portion (10) to derive the positions of selected points (P<SB>1</SB>, P<SB>2,</SB> P<SB>3</SB>, P<SB>4</SB>, P<SB>5</SB> and P<SB>6</SB>) on that aerofoil portion (10). From the derived position data, angular and linear offset data may be calculated to define the deviation of that cast aerofoil portion (10) from the reference position and orientation defined in the computer memory of the laser machining apparatus. That angular and linear offset data is applied to the computer program resident in the laser machining apparatus to control the movement of the laser head relative to the aerofoil surface and to machine the air holes in the aerofoil surface without having to remove the component from the apparatus.
