Abstract: Assay methods are provided or determining an analyte in a sample suspected of containing the analyte. The method is carried out using a composition that includes a conjugate of a first sbp member with a particle. A luminescer is reversibly associated with a nonaqueous phase of the particle. Where the first spb member is not complementary to the analyte, a second sbp member that is capable of binding to the first sbp member is employed. Unbound conjugate is separated from conjugate that is bound to the analyte or to the second sbp member. A reagent for enhancing the detectability of the luminescer is added and the light emission of the luminescer acted on by the reagent is measured.

Abstract: A method for assaying the collagenolytic activity of mammalian biologic fluids by (a) obtaining a specimen of such fluid; (b) applying the fluid to a collagen film bonded to a surface such as that of a glass slide; incubating the slide; washing it; staining it with a dye, and determining the extent of dissolution of the collagen film from the unstained areas of the slide. The collagen film is preferably cross-linked and is preferably bonded to the surface of the slide by baking. The slide is preferably prepared by (a) blending insoluble collagen with a solution of HCl to form a dispersion; applying the dispersion to the slide surface; drying the slide; and baking the slide to cross-link the collagen and bond it to the slide surface. The dispersion applied to the slide contains collagen particles having sizes of at least 1 micron and preferably at least 20 microns. The assay procedure is particularly useful for the determination of the collagenase activity of gingival crevicular fluid (GCF), in which case the fluid specimen is obtained on an absorbent medium such as a filter paper strip. An aspect of the invention is the provision of a kit suitable for use in dental offices which includes (a) absorbent strips; one or more slides having collagen bonded to the surface thereof; and a container of a dye solution capable of staining collagen. The kit may also include one or more collagenase standards.

Abstract: In a device for the paper transport of single sheets and/or continuous paper in office machines, in particular in matrix printers, there are provided in pairs and at least separately driven friction rolls (1, 2) which are disposed rotatably in side plates; the friction rolls exhibit a length to diameter ratio of from 30:1 to 50:1 and are therefore very long and very thin.

Abstract: There is disclosed an enzyme electrode comprising an selectively permeable membrane for permeating sub­stance produced by enzyme reaction selectively. The selectively permeable membrane is obtained as follows. 
     First a mixed composition comprising emu-sion of resin curable by irradiation of ionizing radiation or ultraviolet ray and a water-soluble polymer material is produced. The mixed composition is applied on a film and cured by irradiation of ionizing radiation or ultra­violet ray, thereby the selectively permeable membrane is formed. The selectively permeable membrane is situated between an immobilized enzyme, which is in contact with the sample solution, and an electrically conductive base. 
     As the selectively permeable membrane produced in above processes is excellent in reproducibility and se­lective permeability, it does not allow to permeate interfering substances contained in the sample solution. 
     Therefore, the enzyme electrode detects only the electrode-reaction substance produced by enzyme reaction, thereby permitting accurate measurement.

Abstract: An electrohydraulic servo system forming a control loop for controlling pressure of fluid in a cavity of undetermined volume includes a valve (14) which fluid as a function of position of the valve element (16) is supplied from. An electronic valve controller (40) receives a pressure command signal (Pc) from remote master electrinics (42), and a pressure feedback signal (P) from a pressure sensor (46) in the loop. Such signals (P, Pc) are compared in a pressure-­control mode of operation, and a difference or error signal is employed for generating valve control singals (Ye). A second sensor (44) supplies a position feedback signal (Y). The pressure feedback signal (P) is varied with respective gain (Kp), the position feedback signal (Y) is varied with further gain (Kd), and the difference or error signal is varied with another gain (Ke). Cavity volume is determined as a function of the pressure and position feedback signals (P, Y). Control loop gains, specifically Ke and Kd, are varied as a function of cavity volume for thereby adapting the system for either intended or unintended variations in cavity volume.
