Abstract: A distributed downhole sensor system for a well includes a sensor array comprising. The sensor array includes a plurality of sensors and cable segments. Each sensor is associated with a unique digital address and locatable downhole to capture sensor data simultaneously and output the simultaneously captured sensor data under a first control condition, and a single sensor of the plurality of sensors is configured to capture sensor data independently and output the independently captured sensor data under a second control condition. The cable segments couple the sensors in a line or an array to deliver power to the sensors and provide a communication channel to and from the sensors.

Abstract: A downhole control method for use in a wellbore that includes deploying a first stand-alone hydraulic reservoir downhole; measuring a first downhole fluid parameter; and actuating a first inflow control device, based on the first measured downhole fluid parameter, using the first stand-alone hydraulic reservoir. In one aspect, the first stand-alone hydraulic reservoir and the first inflow control device comprise an open-hole completion system.

Abstract: A downhole control method for use in a wellbore that includes deploying a stand-alone power source and a stand-alone hydraulic reservoir downhole; powering a downhole controller using the stand-alone power source; measuring a downhole fluid parameter; and actuating an inflow control device, using the stand-alone hydraulic reservoir and the downhole controller, based on the measured downhole fluid parameter. In one aspect, the stand-alone power source is selected from the group consisting of a battery and a downhole power generator. In another aspect, the stand-alone hydraulic reservoir, the downhole controller, the stand-alone power source, and the inflow control device comprise a remotely-powered, open-hole completion system.

Abstract: A bone cement mixing apparatus for mixing components of bone cement is described. The apparatus comprises a mixer unit, the mixer unit having a drive mechanism and a mixing cylinder comprising a housing and a mixing mechanism, the mixing mechanism adapted, in use, to mix components of bone cement contained within the housing. The drive mechanism is adapted to create rotational movement of the mixing mechanism with respect to the mixing cylinder housing and to create axial movement of the mixing mechanism with respect to the mixing cylinder housing.

Abstract: A trailer including: i) a draw bar; ii) a trailer frame supporting a trailer bed; iii) an arm including a first pivot mount; iv) an axle pivotally connected to the arm at the first pivot mount; v) an actuating mechanism actuatable to exert a force on the arm relative to the trailer frame. The axle includes at least one associated wheel and the wheel has a plane of rotation in which the wheel rotates when traveling in a forward direction, and the actuating mechanism is located substantially in the plane of rotation. The trailer bed may be raised or lowered by exerting a force on the arm relative to the trailer frame.

Abstract: Disclosed is a bone mixing apparatus (100) comprising a mixing cylinder (110) with ends (111) and (112). End (111) is a closed whereas end (112) is open and capable of being attached to other apparatus. The mixing cylinder (110) forms a cavity within which the mixing of different components used to form bone cement may occur. The mixing cylinder (110) may therefore form a closed sealed container with which hazardous gases formed during the mixing process may be contained. This prevents the hazardous gases from coming into contact with persons in the surrounding area. Attached onto a central region of the mixing cylinder (110) there is a compartment (114) which is used to receive a cartridge (118). The compartment (114) basically functions as replaceable part which forms part of the sealed enclosure. The cartridge (118) comprises different components which go to make up the bone cement.

Abstract: An amalgam and a method of preparing an amalgam for bonding two articles together, which includes mixing a composition of a liquid metal and a metal powder to thoroughly wet the metal powder with the liquid metal, and thereafter mixing a composition with a pestle element for mechanically amalgamating the composition. Other additives may be provided such as ductile metals, additives containing oxides, ceramics, or other non-metallic compounds, and volatile constituents. The amalgamated composition can then wet surfaces to be bonded and harden at or near room temperature.
