Abstract: A method of producing a reagent tape, that includes a base tape layer and a series of consecutive and separate reagent pads of a reagent, is provided for use in a milk sampling device. The milk sampling device is arranged to supply a droplet of a milk sample onto one of the reagent pads on the tape in order to produce a response in the reagent to detect a presence or concentration of a substance in the milk sample. The method includes providing the base tape layer of the reagent tape, applying onto the base tape layer a continuous layer of the reagent, dividing the supplied continuous reagent layer into separate reagent pads by providing a hydrophobic barrier line between said pads. This may be done by laser ablating thin lines of reagent material, or by providing additional hydrophobic material into the layer. Thus, a simple and fast way of providing a tape with pads is obtained, in which a narrow spacing between pads is possible.

Abstract: A scratch testing apparatus comprises a lightweight frame assembly and a test specimen support stage that may hold a test specimen (i.e., the material to be subjected to a scratch test) and may be horizontally moved along slide rails mounted to the frame assembly. A stylus is mounted to a load block and points toward the test specimen support stage to enable the stylus (under load from the load block) to impart a scratch to the surface of the specimen during a scratch test. A load assembly is pivotably mounted to the frame and pivotably supports the load block and stylus, with a moveable counterweight assembly positioned at an opposite end of the load assembly. The position of the counterweight may be varied along the load assembly so as to modify the amount of force exerted by the load block, and thus by the stylus, on the surface of the test specimen, even during the conduct of a scratch test.

Abstract: A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.
