The present invention is one that prevents standard gas from remaining in a standard gas line 3 to prevent a concentration of the standard gas from being reduced due to adsorption, modification, or the like of the standard gas, and has: a diluent gas line 2 that is provided with a diluent gas flow rate controlling mechanism 23; a standard gas line 3 that is provided with a standard gas flow rate controlling mechanism 33; an output gas line 4 that is joined by the diluent gas line 2 and standard gas line 3 and outputs the standard gas having a predetermined concentration; an exhaust gas line 5 that is connected to an upstream side of the standard gas flow rate controlling mechanism 33 in the standard gas line 3 and provided with an on/off valve and a flow rate control part; and a control part 6 that, depending on a flow rate of the standard gas flowing through the standard gas line 3 or the type of the standard gas, switches on/off of the on/off valve.

A system and apparatus for use in flushing at least a portion of a motor with a cleansing fluid. A water inlet apparatus (10) and inlet (20) for flushing a boat motor with fresh water is provided and a system incorporating the apparatus (10) (and inlet 20) is also provided. In particular, the system and apparatus are used to flush a boat motor with fresh water after use. The apparatus has one or more inlets adapted to receive a fresh water source ( e.g. a hose) and a valve, such as a diaphragm valve, that selectively allows flow of the fresh water into the motor instead of its usual water source ( e.g. salt water). Preferably the valve is automatic and is actuated under pressure of the incoming fresh water. The inlet(s) are secured in a surface of the boat inside a basin, which may have a cover (optional) to protect the inlet(s) from the weather/elements.

A pressure-adjustable concealed shower valve includes a shell (2), containing an embedded body (4) with water channels. A cover board (12) that communicates with the water channels is arranged on the body. The body is provided with channels for hot water (22) and cold water (19). The hot water channel and cold water channel are provided with a partition wall with a hole. The partition wall separates water inlets and outlets of the hot water channel and cold water channel. A buffer unit that can be opened and closed is arranged on the partition wall. The buffer unit contains a fixed adjustment screw (10) and the corresponding booster spring (7) and the central rod (6). The end of the central rod matches with the hole on the partition wall and can form an open or close structure. The partition wall and the buffer unit are arranged away from the straight line in which the water channel is located.

A manifold (46) for connection to a medical/surgical waste collection unit is described, wherein the waste collection unit has a receiver (44) for receiving the manifold. Said manifold comprises a housing (158,164) defining a void space. Said housing includes at least one fitting (48) for receiving a suction line (50) that defines a fluid communications path into the void space. The housing further includes a shell formed to have a base (168) and an outlet opening (170) formed in the shell base that is dimensioned to receive a fitting integral with the receiver. A drip stop (174a) is fitted in the housing outlet opening. The drip stop has a valve (187,190) that selectively blocks fluid flow out of the housing outlet opening. The drip stop further has a base (176a) with inner surfaces allowing the base of the drip stop to function as a lead in for the receiver fitting. The drip stop base is formed to have a first inner annular surface (272) that tapers inwardly up from the proximal end of the base and a bead (274) extending circumferentially around the interior of the base. Said bead defines the section of the drip stop base with the smallest diameter opening. The inner diameter of said bead is less than the outer diameter of the receiver fitting (136). The drip stop base is further formed to have a second inner annular surface (276) that extends upwardly from said bead. Said second inner annular surface has a diameter greater than that of said bead.

A manifold (46) for connection to a medical/surgical waste collection unit is described, wherein the waste collection unit has a receiver (44) for receiving the manifold. Said manifold comprises a housing (158,164) defining a void space. Said housing includes at least one fitting (48) for receiving a suction line (50) that defines a fluid communications path into the void space. The housing further includes a shell formed to have a base (168) and an outlet opening (170) formed in the shell base that is dimensioned to receive a fitting integral with the receiver. A drip stop (174,174a) is fitted in the housing outlet opening. The drip stop has a base (176,176a) with inner surfaces allowing the base of the drip stop to function as a lead in for the receiver fitting. The drip stop further has a valve (187,190) extending into the space defined by the outlet opening. The valve selectively blocks fluid flow out of the housing outlet opening. The housing is further formed to have a lip (172) that extends downwardly from the shell base, extends around and is spaced radially away from the housing outlet opening. The drip stop base is formed to have a slot (178,178a) around its outer perimeter, wherein the drip stop seats in the housing outlet opening so that the perimeter section of the shell base that defines the housing outlet opening seats in the drip stop base slot and the section of the drip stop base below the slot defining section seats inside a space defined by said housing lip.
