Abstract: A method for testing a tunnel fire suppression system in the form of a water deluge system having a wet side and a dry side separated by a valve, includes the step of providing a nozzle arrangement comprising a plurality of nozzles, with each nozzle disposed in or coupled to an outlet of the water deluge system. The nozzle arrangement comprises, is coupled to or operatively associated with a sensor arrangement configured to measure the pressure of air at each of the plurality of outlets of the water deluge system and output one or more output signals indicative of the pressure of the air at the one or more outlets. The method includes providing a supply of pressurised air through the water deluge system using a blower coupled to the water deluge system.

Abstract: An apparatusfor testing a water deluge systemhaving a wet sideand a dry side separated by a valve comprises a blower configured for coupling to an inlet of the water deluge system The blower provides a supply of pressurised air through the water deluge systemfrom the inlet to one or more outlets of the water deluge system. A sensor arrangement is associated with one or more of the outlets and configured to measure the pressure of the air at the one or more outlets and then output one or more output signals indicative of the pressure of the air at the one or more outlets. A communication arrangement conveys the one or more output signals from the sensor arrangementto a processing system configured to determine from said one or more output signals the flow rate of the air supply at the one or more outlets.

Abstract: The invention provides a fluid discharge apparatus (102) and a method of use. The apparatus (102) comprises a body (106) comprising an inlet (122) configured to receive fluid from a fluid source, and one or more fluid discharge ports (140). A valve arrangement (124) in the body (106) is operable to be cycled to provide an interrupted flow of fluid through the body (106). The valve arrangement (124) may be disposed in the body (106), and/or may be operable to be moved between a first condition in which fluid entering the body (106) from the inlet (122) is prevented from passing through the apparatus (102), and a second condition in which fluid is discharged through the one or more fluid discharge ports (140). The valve arrangement (124) may be operable to cycle between the first condition and the second condition to provide an interrupted flow of fluid through the body (106).

Abstract: A communicator (1) for monitoring a worker in a work environment when carried or worn by said worker, the communicator (1) comprises: a transmitter (7) for communicating with abase station remote from the communicator (1); a location monitoring means (3) for monitoring the location of the communicator (1) and for continuously or intermittently sending to the base station worker location data associated with the respective communicator (1) and/or the worker wearing or carrying the communicator (1); a fall detection device (4) configured to detect a fall event of a worker carrying or wearing the communicator (1); an input means (5) operable by the worker carrying or wearing the communicator (1); and an alarm (8; 9) configured to activate if a fall of the worker has been detected by the fall detection device (4), where the communicator (1) is configured to transmit a fall warning to the base station using the transmitter (7) when the fall detection device (4) detects a fall event of a person carrying or wearing

Abstract: An apparatus and method for use in welding together sections of coiled tubing (6) in the oil industry, wherein the apparatus has a container (14), legs (12) which can be adjusted to adjust the height of the container (14), welding apparatus in the container and slots in the walls of the container. In use the container is raised to the height of the coiled tubing which is to be joined. A winch pulls the ends of the coiled tubing towards a clamp, which holds the two ends of the coiled tubing fixed inside the container, while the ends are welded together. The slots in the walls allow the joined tubing to pass out of the container after the weld is completed. The container provides a controlled environment for welding and weld inspection.
