Abstract: A sheet overlapping detecting method includes the following steps. A predetermined level value V os  is set as the level of a light emission signal. On the basis of a value V ik  of a light reception signal obtained upon light reception based on light emission corresponding to a light emission signal having a predetermined level value V os , an optimum value V od  corresponding to the input value V ik  is calculated in accordance with a prestored V ik  - V od  characteristic table. The calculated optimum value V od  is set as the level of the light emission signal to drive the light-emitting device (1,21-1,21-2). On the basis of a value V ik  of a corresponding light reception signal, a change value V₁₋₂ corresponding to the input value V ik  is calculated in accordance with a prestored V ik  - V₁₋₂ characteristic table. A determination level V L  is calculated in accordance with the following equation: 
V L  = V₁ - V₁₋₂·1/2 
where V₁ is the value of a light reception signal obtained when the optimum value V od  is set as the level of a light emission signal. Overlapping of sheets to be fed is detected in accordance with the calculated determination level V L .

Abstract: Known blood collection and phase separation containers include a compartment which serves for both collecting blood and separating it during a centrifuging operation. However, these containers tend to be complicated as means need to be provided to prevent the separated blood from remixing after centrifuging. Described herein is a container (10) for phase separation of at least two phases via centrifugation in which mechanical means are provided to prevent remixing. Remixing is prevented by the use of a plurality of plates (60) spaced from and extending parallel to one another which are incorporated into the container (10). The plates are preferably attached to one wall (24) of the container (10) at (62) and are inclined at an angle (β) to prevent flow of the heavier phase present in one region (A) of the container (10) into the lighter phase in region (B) whilst the lighter phase is being withdrawn from the container (10).

Abstract: For producing a bend or corner in a sealing strip 16, to match the shape of a bend or corner in its mounting flange, a portion of the sealing part 26 is removed between parts 26A and 26B, so as to produce a correspondingly shaped cut-out. The sealing strip is then placed within a mould cavity 54 which is curved to match the required configuration for the bend or corner and has an internal surface matching the external surface of the sealing part 26. A metal core 60, having a cross-sectional size matching that of the hollow interior of the sealing part 26, is placed in position within the cut-out by a swinging arm 58. Moulding then takes place whereafter arm 58 is swung outwards so as to withdraw core 60 (portion 26B has to be partially flattened to facilitate this). A small part D of the cut-out, which is blocked by, arm 58 during the moulding process, is left open. This is then closed off by a further injection moulding operation using a short core matching the cross-sectional shape of the core 60. This short core has a narrowed neck by means of which it can be pulled out of the sealing part 26B through a small hole in the sealing part which is thereafter closed by a grommet.
