  • Patent number: 10874888
    Abstract: A method of providing a deluge system (10) on a boom (12) such as a boom that is used to conduct well flaring operations at an end thereof. The deluge system comprises a base unit (30), a stanchion (20), and a nozzle apparatus (22); the method comprising attaching the deluge system to a burner boom with a walkway, such that there remains a width of at least 30 cm clear passage on the boom's walkway after the deluge system has been attached. This provides an escape and/or rescue route for personnel should a dangerous situation occur, such as uncontrolled fire or personnel falling overboard. In preferred embodiments, the deluge system is attached to the boom outboard of handrail supports (which includes on a single handrail). The deluge system may have its own mechanism e.g. a winch, for moving the stanchion from a stowed position to an operative position which allows a safe and more optimum positioning of the stanchion away from the well flaring operation, as herein described.

  • Patent number: 10865753
    Abstract: An injection hole has an injection hole passage communicating an inner opening with an outer opening. The inner opening is smaller than the outer opening in cross-sectional area. The needle moves in a valve closing direction to abut against a valve seat to restrict a flow of fuel through the injection hole. A first inner wall of the injection hole is located on a valve closing direction side relative to an injection hole axis. A second inner wall of the injection hole is located on an opposite side of the injection hole axis from the valve closing direction side.

  • Patent number: 10850144
    Abstract: A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component with a distal base, a distal movable member, a proximal base, a proximal movable member, and a bias member biasing the proximal movable member from a preactivation position to an activated position located proximally of the preactivation position. A thermally responsive element is retained by the distal base, loses structural integrity under occurrence of a predetermined thermodynamic condition, and thereby allows the distal movable member to move from a preactivation position to an activated position with respect to the distal base. A flexible connector connects the proximal movable member to the distal movable member. Upon the loss of structural integrity by the thermally responsive element, a biasing force from the bias member causes a movement of the proximal movable member from the preactivation position to the activated position.

  • Patent number: 10842090
    Abstract: A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.

  • Patent number: 10814837
    Abstract: An object of the present invention is to suppress variations in shape of flow channels to have an enlarged flow channel. When an attachment main body 51 of a lid member 50 is attached to a recessed attachment part 46 of a main body member 40, a pair of flange parts 52 provided to the lid member 50 abuts on the main body member 40. Therefore, the insertion amount of the attachment main body 51 into the recessed attachment part 46 in each product can be maintained approximately constant while enlarging a main channel MC and a pair of sub channels SS1 and SS2, which are formed by the main body member 40 and the lid member 50, and variations in shape of these flow channels can be reliably suppress.
