Abstract: A peristaltic pump is provided, which may have auxiliary fluid introduction, for a plurality of resilient pump tubes progressively occluded concurrently along a portion of their lengths, recurringly, to advance fluids therethrough by a pressure roller assembly; and a control system for the pump to render the roller assembly inoperative to advance fluids. A platen is mounted for movement from an operative position, in which the pump tubes are engaged and sandwiched between the platen and the roller assembly, to an inoperative position in a direction away from the roller assembly. In the inoperative position of the platen, a tube or tubes of the auxiliary fluid introduction, which includes a pressure pin cooperating with a pad engageable with the tube or tubes therebetween, are released. The platen is power-operated to move to at least one of the two aforementioned positions thereof.

Abstract: There is provided a method and apparatus for sampling a viscous liquid by aspiration of such liquid from a container in an offtake tube of a probe insertable in the container. A reagent having the characteristic of a solvent is added to the sample to dilute it within the probe after a relatively short distance of travel of the sample within the probe. The reagent is fed into the probe at a first predetermined flow rate and the admixture is aspirated at a second predetermined flow rate which is faster so that the sample is aspirated at a rate determined by the difference between the first and second flow rates.

Abstract: There is provided a method and apparatus for optical analysis by photometry of a substance flowing in a liquid stream within a coaxial sheath stream of a transparent liquid. The sheath stream, flowing in the same direction, entrains the inner stream so as to confine it concentrically. A photometer is used which includes a light source on one side of the sheathed stream in a position to direct light onto the inner stream which is cylindrical, the outer or sheath stream also being cylindrical. The photometer also includes a light detector externally of the sheathed stream in an angular position to detect the photometric results of impingement of light on the contents of the inner stream. Refraction of light at the interfaces of the sheath stream is compensated by varying the radius of the inner stream through the control of the flow of one stream with reference to the other. The concept also includes the narrowing of the sheathed stream to a very small diameter in which it is confined by a wall structure in the area of examination.

Abstract: New and improved fluid supply control method and apparatus for periodic fluid merger which are particularly adapted to the periodic, precisely timed introduction of precisely and uniformly sized fluid segments into a fluid stream are disclosed and comprise a segmenting fluid supply line which respectively connects with a pressurized source of said segmenting fluid at substantially constant pressure and with the line in which said fluid stream is flowing. First and second, quick-acting flow interrupting means are operatively associated with said fluid supply line at spaced locations thereon, and a cavity of substantially constant volume is formed between said flow interrupting means. In operation, and for the formation of each of said segments, said first flow interrupting means are opened to effect the filling of said cavity with said pressurized fluid whereupon said first flow interrupting means are closed and said second flow interrupting means opened to effect the flow of said pressurized fluid from said cavity into said fluid stream to form said segments. A form of the invention is disclosed wherein said fluid supply line is constituted by a compressible, resilient tube and said flow interrupting means comprise means to compress and close said tube at spaced locations thereon. In this disclosed form, the cavity is formed by the volume of the tube which extends between said flow interrupting means.

Abstract: A system for testing a plurality of samples for a characteristic, such as the blood group typing of blood samples, includes supplying the samples seriatim as a flowing stream, adding a reagent which will provide an agglutination-type reaction with samples having a predetermined characteristic, continuously concentrating any agglutinated-type material in each sample into a predetermined stratum and continuously separating this stratum from the remainder stratum, and continuously disposing one of these strata on the surface of a continuously advancing medium. The surface of the medium may be examined for the presence of agglutinated-type material. Each sample may be divided into quotients and each treated with a different reagent, and the resulting strata may be disposed on the same medium. In any event, the reaction occurs in the flowing stream, and the results are disposed on the medium for examination and storage.
