Abstract: An object is to provide an emergency detachment device of a fluid handling device, the emergency detachment device having exceptional heat insulation performance and making it possible to handle extremely-low-temperature fluids such as liquid hydrogen. A first coupler 2 and a second coupler 3 are provided with a vacuum section 10 between an inner pipe section 5 and an outer pipe section 6, and are provided with two valves 1 in series. A remaining-fluid-transferring mechanism is provided such that, after second valves 1B provided further inward enter a closed-valve state during emergency detachment, residual fluid that remains closer to the first valves 1A than the second valves 1B is transferred into the inner pipes sections 5 provided further inward of the second valves 1B.

Abstract: A water supplying extension arm for supplying water from a water source to a showerhead has an elongated hollow extension arm element extending along its axis and having a first end connectable to the water source and a second end spaced in a direction of its axis and connectable to the showerhead, and a water regulating element operatively connected with the second end of the elongated hollow extension arm element and adjusting an amount of water issuing from the second end of the elongated hollow extension arm element to the showerhead.

Abstract: The method relates to a method and a device for controlling the flow of a liquid. In a well (10) having at least one inlet (11) and one outlet (12) the areas of said inlet (11) is adjusted in dependence on the liquid level in said well (10) by a floating body (13) controlled by said level. Said well is provided with an inlet tube (15) ended by said inlet (11), and at least one outlet (12), a floating body (13) arranged movable in a vertical direction in said well (10), and a slide (14) arranged in said well (10) in front of said outlet (12), said inlet tube (15) and said slide (14) being movable in relation to each other in dependence of a movement of said floating body (13) so as to close adjustably by said slide said inlet (11) of said inlet tube (15).

Abstract: A fluid loading arm emergency disconnection system comprising two pipe elements each including a normally closed valve that can be opened when said pipe elements are connected, means for sensing a connection between the arm and a receptacle, means for sensing a predetermined angular arm configuration, and means for disconnecting the arm when the connection and predetermined arm configuration are sensed simultaneously.

Abstract: A mixer-unit is attached to the cold and hot water mains and serves to adjust the quantity and temperature of the water. The mixer unit is not fitted with an operating handle or lever, the adjustment of the water quantity and temperature is achieved by pivoting the water outlet about two independent axes of movement. Disc-shaped regulating elements serve for the independent adjustment of both the water quantity and temperature which are operable by means of a cam connected to the rotatable and pivotable water outlet.

Abstract: In a grip-less water mixer unit, the quantity of water outflow and the mixing temperature are controlled by pivot-mounting the water outlet about two independent axes in a valve body. The water outlet is coupled to two regulating elements of which, one serves to regulate the water quantity and the other the adjustment of the mixing temperature. In a first embodiment example both regulating elements are formed as cylindrical bodies rotatable in the valve body, and in a second embodiment example, both regulating elements are concentrated in a ball which is rotatable in the valve body.

Abstract: In order to make possible, with a valve having a sleeve (110) provided with a valve seat (112) and with a valve activating tube (118) which supports a spring-biased valve body (114) which can be tipped away from the valve seat (112), a high water flow rate even under low water pressure, it is proposed, instead of a support of the valve body (114) on the valve seat (112) during valve opening, which inhibits water flow and causes wear, as is the case with a valve which closes with water pressure, to provide the sleeve (110) in a valve which closes against the water pressure with an axial, annular shoulder (133), the diameter of which is larger than the diameter of the valve seat (112) and on which the frontal surface (162) of the tube (118) nearest the annular shoulder (133) is supported.

Abstract: A pull away spill guard comprising an automatic shut-off valve positioned in a supply line used in transferring liquids from one container to another. The valve acts to automatically shut off the flow of liquid through the system if the system becomes accidentally over-pressurized or there is a separation or disrupting movement in the system operating between the two tanks.

Abstract: A pipe header assembly for well point pumping apparatus for use with a series of well point risers forced into the ground and extending above ground where they are connected to a pipe header whereby water is pumped out of the ground and conveyed through the pipe header to the pumping apparatus for discharge elsewhere. The assembly includes swing arms connected to the pipe header by an improved slip joint at one end of the swing arms and located between the swing arms and the header and by means of which the swing arms can be inserted in or removed from the pipe header without the necessity of saddles, fittings, threaded joints, or other connections.A tool, referred to as a jetting adapter is also provided for quick connection to a plain end of the well point risers, which adapter can be simply slipped over a plain end of the riser where it then automatically locks on the riser.

Abstract: There is disclosed a faucet of the "washerless" construction employing a spherical valve member in a hemispherical valve body in which the spherical valve member has only a single protruding tubular member that serves both as the valve member operator and the discharge nozzle for the faucet.
