  • Patent number: 8815136
    Abstract: The present invention relates to a method for the production of bodies in plastic comprising two portions hinged to each other by a single rotation pin. The method comprises the steps: a) predisposing a mold with two distinct forming chambers for the two portions; the mold comprises a third chamber for the single pin, made and positioned in such a way that the pin is formed already aligned along the hinge axis; the mold is provided with a pair of pegs axially distanced from each other to form the third chamber and sliding along the axis between a first and a second operating position; b) positioning the pegs in the first position; c) injecting plastic material inside the chambers; d) shifting the pegs from the first to the second position, bringing the pin to engage inside the seats; e) opening the mold and extracting the two assembled portions.

  • Publication number: 20030202242
    Abstract: A slide for the microscopic examination of biological fluids, such as urine, blood, spinal fluids, designed to count particles or elements (e.g., corpuscles) present in a predetermined sample. The slide has two plates made of a transparent material, which distinguish on their inside at least one well that is filled, by capillarity, with drops of biological fluid deposited onto the slide itself. Counting chambers are formed on the bottom of at least one well. Each chamber defines a precise volume of biological fluid to be examined. The slide is characterized by the particular and innovative shape and definition of these counting chambers. In particular, the counting chambers have a bottom surface with a roughness differing from the roughness of the boundary defining or demarcating the counting chamber.

  • Publication number: 20030197927
    Abstract: A slide for use in microscopic examination of biological fluid is constituted by two plates of transparent material, one plate being a bottom and the other plate being a cover, the plates forming wells which are filled by capillarity with the biological fluid to be examined. A plurality of reliefs form a plurality of computation chambers in each well. The reliefs which define each computation chamber sectioned along a plane perpendicular to the bottom of the well have a shaped section along a profile assimilable to a polygon having at least one right angle.
