Abstract: A method of producing a side pocket mandrel body for use in a hydrocarbon well side pocket mandrel assembly includes providing a continuous, solid piece of material with the through-going main conduit; in the solid piece of material, forming said at least one side pocket by machining a bore, displaying an external entrance opening, into a laterally offset section of the solid piece of material generally parallel to the main conduit such that an internal wall section of the solid piece of material is brought to separate the main conduit from the machined bore; plugging the entrance opening of the machined bore with a fluid-tight plug; providing at least one opening from an outside of the mandrel body into the at least one side pocket; providing at least one opening in the wall section; and providing the solid piece of material with the first and the second connection arrangements, thereby rendering the mandrel body connectable to the up-hole and down-hole sections of the production tubing.

Abstract: A gas lift valve for use in a hydrocarbon well includes an elongated valve housing including an inlet port for receiving a fluid from an annulus of a hydrocarbon well, and an outlet port for delivering the fluid to a production tubing of the hydrocarbon well, and an elongated, internal valve body, which is movable along a longitudinal, central axis of the valve housing between a first end position and a second end position. In the first end position, a sealing surface of the valve body is in sealing contact with a valve seat surface of the valve housing prohibiting the fluid to flow from the inlet port to the outlet port, and in the second end position the sealing surface is separated from the valve seat surface allowing the fluid to flow from the inlet port to the outlet port. The outlet port is positioned at a terminal end of the valve housing.

Abstract: A fish handling unit for processing live fish is provided. Such fish handling unit includes an inspection system configured to inspect a plurality of live fish. A conveyor assembly transports the live fish to the inspection system. At least one robotic cell is in communication with the inspection system. The robotic cell has a controller configured to control operation thereof. An end effector is operably engaged with the robotic cell. The end effector interacts with the live fish moving along the conveyor assembly, based on information determined by the inspection system and received by the controller. The end effector may optionally be an integrated gripper and injection assembly capable of orientation and injection of the live fish. Associated devices and methods are also provided.

Abstract: An ASK/OOK transmitter includes a frequency-shift keying (FSK) modulator receiving an input bit sequence and generating a FSK modulation signal indicative of the input bit sequence, a frequency generation circuit receiving the FSK modulation signal and generating a carrier signal having a first frequency where the frequency of the carrier signal is shifted by the FSK modulation signal to form a wideband carrier signal, an amplitude-shift keying (ASK) modulator receiving input data and generating an ASK modulation signal indicative of the input data, and a power amplifier coupled to receive the wideband carrier signal as an input signal and the ASK modulation signal as a control signal. The power amplifier provides a spread spectrum ASK transmission signal where the ASK modulation signal modulates the wideband carrier signal to form the spread spectrum ASK transmission signal.
