Further, the robot control system comprises a control unit (50), a robot driving means, a seal (70) for isolating the confined area from the external environment and at least one transmission member (80), wherein the control unit is configured to send control signals to the robot driving means, and the at least one transmission member extends from the robot driving means to connect to the articulated robot, the at least one transmission member extending through the seal.

Abstract: Cross-web for use in cable manufacture having a tape-like appearance in their relaxed state and their method of manufacture.

Abstract: An apparatus for detecting the presence of liquid in a high pressure gas pipeline (4) is described. The apparatus comprises a sight glass (2), providing a window into the inside of the pipeline, and a light sensor (1), for receiving and sensing reflected light from the inside of the pipeline through the sight glass. The apparatus also comprises a processor, for automatically detecting the presence of a liquid based on the sensed reflected light. In this way, automatic detection of the presence of liquid in a gas pipeline can be achieved based on the measurement of reflected light, which can be expected to differ when liquid is present compared with when no liquid is present. No visual inspection by an operator is required—although the data can be stored for later operator use or verification if necessary.

Abstract: A sight glass apparatus for viewing the interior of a pressurised vessel, chamber or a pipe conveying fluid under pressure is described. The sight glass apparatus comprises a sight glass assembly mounted over an opening into the vessel, chamber or pipe, the sight glass assembly comprising a sight glass adjacent the opening which provides a window to the inside of the vessel, chamber or pipe, and a containment vessel mounted behind and/or around the sight glass assembly for containing fluid exiting the opening in the pipe in the event that the sight glass assembly fails. In this way, even if the sight glass assembly fails, the pressurised fluid within the pressurised vessel, chamber or pipe is safely contained.

Abstract: An optical chemical analyser comprises a source of a first amount of radiation (46), an optics module configured to direct the first amount of radiation such that it is incident on or passes through a target (14) at a target location, the optics module further being configured to receive a second amount of Raman scattered radiation from the target and direct the second amount of radiation (206) to a Spatial Interference Fourier Transform (SIFT) module, the SIFT module including a first dispersive element (216) and a second dispersive element (218), the SIFT module being configured such that a portion of the second amount of radiation is received by the first dispersive element and interferes with a portion of the second amount of radiation received by the second dispersive element to form an interference pattern; the SIFT module further comprising a detector (48) configured to capture an image of at least a portion of the interference pattern and produce a detector signal (226) based on the captured image; an

Abstract: A method for determining a path through concept nodes. The method includes calculating a spatial cost function between adjacent concept nodes in a lower dimensional layout representation of a network of concepts in a n-dimensional space and determining a path that follows a minimum spatial cost function through the concept nodes. The spatial cost function may be used to predict a next node in the path. The method may also include receiving an origin concept node or a goal concept node.

Abstract: A signal analysis instrument (10) and a receiver. The signal analysis instrument (10) comprises a computer (12), a phase shift mechanism, a receiver mechanism and data acquisition device. The phase shift mechanism comprises an input (100) for receiving a first high frequency signal; a phase shifter (114) arranged to act on the first high frequency signal to produce a phase-shifted first high frequency signal; and a phase shift controller (116) arranged to control operation of the phase shifter (114) in response to instructions from the computer (12). The receiver mechanism comprises a mixer (104) and a first signal conditioning circuit (106). The mixer (104) is responsive to the phase-shifted first high frequency signal and to a second high frequency signal to produce a mixer output signal. The first signal conditioning circuit (106) is responsive to the mixer output signal to produce a receiver output signal.
