Abstract: Apparatus and a method for killing a live well after activation of a well blowout preventer is described. This is achieved by providing apparatus in the form of a shear or kill sleeve (34) in a string (26) above a sub-sea test tree and which is located between the pipe rams (22, 24) and shear rams (18) of a blowout preventer (12). In the event that the shear rams (18) are activated and seal the string above the kill sleeve (34), the sleeve includes a pressure sensitive valve (84) which may be opened, by pressurising between the blowout preventer rams (18, 22), to permit fluid to be pumped from the blowout preventer (12) through the valve (84) and into the string (40), to choke or kill the well. After the well has been killed, the blowout preventer (12) may be opened to permit removal of the well tools. Embodiments of the invention are described.

Abstract: A two-part electric motor shaft assembly. The assembly includes an elongated shank member which has a cavity hollowed out at one end. A cam pin has one end configured to be received in the shank cavity and secured thereto. The other end of the cam pin forms a cam surface which is eccentric with respect to a longitudinal axis defined by the elongated shank member. By utilizing a two-piece design, the shank member may be formed of a softer and less expensive material than the alloy steel used to form the cam pin since the shank member is subjected to less loading and wear. The two-part motor shaft assembly of the present invention eliminates the stress riser that occurs with application of loading to the transition joint of a single piece design.

Abstract: Copper wire coated with a layer of zinc is heated to a temperature (T.sub.1) sufficient for the formation of a brass phase .beta., and the temperature is maintained until complete diffusion of the zinc. The thickness of the zinc covering can be chosen in such a way that once the zinc is completely diffused, the wire consists of a brass phase .beta. in its periphery and of copper in its central part. The wire is then heated to a temperature (T.sub.2) necessary for the formation of brass phase .alpha., and the central copper part of the wire is transformed into brass phase .alpha..

Abstract: Apparatus and method of isolating a well to allow intervention equipment to be installed in the upper section of tubing and surface equipment to be tested prior to running in the well is described which enables a surface test tree to be leak-off tested on a regular basis and enables the SSTT valves to be pressure tested before opening and after relatch. This is achieved by providing a completion lubricator valve comprising a fail open valve (18) located above a conventional downhole safety valve (20), the fail open valve (18) being closable by the application of hydraulic closure pressure (42) to allow a pressure differential to be supported from above. The valves (18, 20) are flapper valves and are spring-biased to open or closed positions as necessary. This allows the intervention equipment to be installed in the upper section of the tubing and the surface equipment to be tested prior to running in the well and enables the injection head to be installed immediately upon the production tree.

Abstract: A piston for an internal combustion engine includes a textured, macroscopic, relief pattern on the inner and/or outer face of its skirt portion. The pattern improves heat transfer and oil flow, and decreases the weight of the piston, while maintaining or enhancing its strength. The pattern may be formed in the piston when it is molded, or it may be formed thereupon after molding by a chemical etch process.

Abstract: The invention relates to stabilisation devices for down-hole drill motors and provides such a device comprising a tubular motor body portion (18) adapted for rotational movement on a selective basis to provide a steering capability, a motor shaft (16) passing through the body portion (18). A lower end portion of the shaft provides an end surface (20) for attachment of a tool (32) by a bit attachment means (28, 30) provided within a lower end of the shaft. The lower end of the shaft (16) has an external diameter less than the internal diameter of the motor body portion so as to be either completely or partially received within the body portion to enable the overhang distance between the operating faces of the bit and the stabiliser on the bearing housing to be as short as possible. Alternatively the end face (20) of the shaft may project slightly (.ltoreq.5 cm) from the end face (22) of the motor body portion (18).

Abstract: The invention pertains to a method and a device for die sinking and wire-cutting workpieces by means of electrical discharge machining. A machine frame (10) as well as a worktank (9) and a lower guide head (5) form a stationary unit referred to the main axis directions X, Y. The workpiece (2) is immersed in the worktank (9) and moved in the horizontal plane by means of the X/Y main axis drive (14). An upper guide head (4) also forms part of the stationary unit or can be moved by means of a Z drive (16) and/or a U/V drive (15). The lower guide head may also be designed such that it can be vertically moved by means of a lower Z drive (17). This concept is particularly suitable for producing microscopic components by means of electrical discharge machining and as a multielectrode machine that processes workpieces simultaneously or sequentially.

Abstract: A security system includes an intrusion detector having a transmitter coupled with a portable receiver to alert a homeowner or the like that an intrusion has taken place or occurred within a pre-set time period. The area under surveillance is monitored by an infrared detector which activates the transmitter upon the receipt of abrupt differences in infrared radiation levels, associated with the presence of a warm body in an otherwise equilibrated environment. A radio signal is emitted by the transmitter upon activation by a transmitter-receiver carried by the homeowner or the like as he/she approaches the protected area. The radio signal from the transmitter is received by the portable remote transmitter-receiver. A first signal, indicating that an intrusion has been detected in the monitored areas, is displayed on the receiver for a preselected period of time.
