Abstract: A liquid diluting and transfer valve has disc like valve elements provided with faces frictionally engaged. The valve further includes passageways for passing both sample liquid and rinse liquid and a continuous groove formed in one of the respective faces. This continuous groove effectively isolates the passageway openings to the faces and is capable of blocking passage of leakage material along the face to the periphery of the engaged face.

Abstract: A few large, fast rising gas bubbles are generated near the bottom of a sample container and the upward movement of the bubbles causes a mixing action of the sample. The bubbles result from the periodic injection of discrete quantums of gas into the bottom of the container. The volume of a discrete gas quantum determines the size of a resulting bubble. Both the volume and frequency of generation of the quantums of gas are controlled by a timing circuit which operates a solenoid valve that permits each discrete quantum of gas to pass into the sample container.

Abstract: A liquid transfer valve having an internal segmenting passageway and at least one external hollow loop of precise internal volume thereby to provide the different volumetric amounts of a liquid sample for dilution, each amount directed with a common amount of diluent at the same time to different predetermined locations. An additional external loop is provided, if desired, to give the same valve assembly the capability for dealing with a prediluted sample to be directed first to a first testing apparatus and next, as a segmented portion with a given amount of diluent to a second testing apparatus. Structure is provided to accomplish rinsing (backwashing) with diluent during the delivery condition of the valve.

Abstract: A valve for transferring liquid intended to be used in a dilution system, to provide at least a pair of different segmented samples from a source supplying them, the volume of one of the segmented samples being different from the volume of the other segmented sample of said pair, said transfer valve having a first portion intended to receive and isolate in its interior an amount of the liquid sample and to combine said sample quantity with a first volume of a diluent, to produce a first precise dilution desired, a second portion of the transfer valve to receive and isolate therein a different amount of liquid sample and to combine such a sample amount of the liquid and to combine such a quantity of sample with the same quantity of diluent, in order to produce a second dilution, characterized said transfer valve because in the first p cited section (20) thereof is included a segmental passage (p1, p2) formed inside said valve and in that the second portion (24) of the transfer valve comprises a hollow element in the form of a loop (p15p17) ), of a precise internal volume.

Abstract: A liquid diluting and transfer valve (10) with disc like valve elements (12, 14, 16) with faces (12', 14', 14'', 16') which are frictionally engaged. Each disc like valve element (12, 14, 16) further includes passageways (30, 64, 66, 70, 73, 32) which can be used to pass both sample liquid and rinse liquid. A continuous groove (100) is formed in one of the respective faces (12', 16') for effectively isolating the passageway openings (30, 64, 66, 70, 73, 32) to the face (12', 16'). The continuous groove (100) is capable of blocking passage of material leaking along the face (12', 16') to the periphery of that engaged face (12', 16').
