摘要:
An NO-accumulation apparatus, method and use, comprising: a container (120) defining a cavity for accommodating a liquid (105), an inlet (150) for feeding the liquid into the container (120) and an outlet (151) for delivering the liquid from the container (120) to a bath unit; an NO-gas dissolving unit (140) for dissolving gaseous NO in the liquid (105) to produce an NO-containing liquid, wherein the NO-gas dissolving unit (140) is arranged in the container (120) and/or forms a part of the container (120); and an NO-gas port (110) in fluid communication with the NO-gas dissolving unit (140), wherein the NO-gas port (110) is adapted for coupling, particularly for releasably coupling, with an NO-gas supply, whereby the apparatus further comprises means for decoupling the inflow of NO to the liquid (105) within the container from the removal of the NO-containing liquid (NO-decoupling means), so that the removal of the NO-containing liquid is inhibited, when the NO is flowing into the liquid, and also the NO inflow is inhibited when the NO-containing liquid is removed from the container (105).
摘要:
A seal system (1) for use in mixing apparatus (2) comprising a rotating shaft (3) which passes through a fixed structure (4), the seal system (1) being adapted both to prevent egress of content from the apparatus, and to resist ingress of material into the seal system.
摘要:
Apparatus for biochemical synthesis comprises a reaction vessel, a temperature control device for the reaction vessel, a plurality of reservoirs for reaction components, and a supply/withdrawal means, e.g. comprising reciprocating syringe pumps and switchable valves. Agitation of a reaction mixture is effected by withdrawing a part of the mixture from the reaction vessel and returning it thereto.
摘要:
Disclosed is apparatus for distributing a solid, gel, powder or viscous test substance in an extraction fluid, the apparatus comprising a flow cell 2 for holding the test substance and having an inlet 4 and an outlet 6; an extraction chamber 8 located between said inlet and outlet comprising a convergent nozzle 10; and a recirculating pump 14 for driving extraction fluid: (i) into the flow cell via the inlet; (ii) through the extraction chamber; and (iii) back to the flow cell via the outlet, whereby a pressure differential is established across the extraction chamber such that the velocity of the extraction fluid is greater at the outlet than at the inlet; characterized in that the apparatus further comprises a tortuous path flow control valve (TPV) 12 located at the outlet and configured to permit flow of extraction fluid and extracted test substance 16 but to prevent or retard passage of said test substance 16 through the outlet.
摘要:
A domestic carbonation appliance has a replaceable CO 2 cylinder and accepts a refillable bottle with a removeable cap. The cap can cooperate with a carbonation head of a domestic carbonation device but lacks bayonette or thread features for engaging the carbonation head. The device provides for "one-touch" carbonation.
摘要:
A dispensing assembly for dispensing a mixture of fluids is provided. In some embodiments, the dispensing assembly includes a first valve for selectively permitting fluid flow to a mixing chamber in which a second fluid is introduced, wherein the valve is actuated between open and closed positions responsive to fluid pressure downstream of the mixing chamber. In such embodiments, the fluid pressure downstream of the mixing chamber can change based upon whether fluid is dispensed from a spray gun, wand, nozzle, or other dispensing head of the dispensing assembly.

摘要:
A refrigerator is proposed comprising a fluid mixing apparatus (100) for adding a gas, contained in a storage bottle (125) provided with a valve device (130), to a liquid within a mixing chamber (105); the mixing between the gas and the liquid within the mixing chamber forms a composite solution of mixed gas and liquid and gas being not mixed with the liquid. The pressure value of said non-mixed gas is indicative of the amount of mixed gas within the composite solution. The fluid mixing apparatus according to an embodiment of the present invention comprises a pressure detector (199) configured to detect the pressure value of the non-mixed gas within the mixing chamber; and control means (145, 165, 170, 175, 180, 185, 190, 195, 197) for controlling, as a function of the detected pressure value, the opening or closing of said valve device in order to automatically adjust the gas flow from the storage bottle to the mixing chamber.
