    Abstract: A fuel flow rate measuring device comprising a control rod axially movable in proportion to the rate of flow of air flowing through a suction pipe, a ball disposed in a taper bore and adapted to be moved in the taper bore by the control rod, the taper bore and the ball cooperating with each other to define a clearance which is variable in proportion to the rate of flow of the air, and a pressure regulator provided between a fluid inlet and outlet for keeping constant the fluid pressure difference across the clearance defined by the taper bore and ball.

    Abstract: By using a reagent for latex agglutination reaction which contains one or more members selected from the group consisting of a compound of the formula ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl group or an amino group which may be substituted with a lower alkyl group and R.sup.2 and R.sup.3 are each a hydrogen atom or a lower alkyl group, and a di-lower alkyl sulfoxide, the non-specific agglutination can be remarkably prevented and thus greatly improving the reliability of the latex agglutination test results.

    Abstract: In the rubella virus hemagglutination-inhibition test, the hemagglutination-inhibition antibody titers of the test sera can be determined with accuracy and high sensitivity by employing a novel diluent, which contains N-2-hydroxyethylpiperazine-N'-2'-ethanesulfonic acid in a low concentration and which is free from calcium ion, for the dilution of the rubella virus hemagglutinating antigen and of the test sera.
