Abstract: A pipe-clip, comprising an annular clip body (1) formed from a flexible strip, the ends of which are provided with flanges (2,3) adapted to be pulled together by means of a fastening screw and nut (5,6), in which one (2) of the flanges has an outwardly opening slot (4) adapted to laterally receive the shank (6) of the fastening screw (8). According to the invention the nut (5) is incorporated in an auxiliary part (9) that normally bears on that side of the second flange (3) which is turned away from the first flange (2), said auxiliary part (9) being fastened in such a way, that it may resiliently bend away from said second flange (3) through a certain angle about an axis located adjacent the transition between the annular clip body (1) and said flange (3), said second flange (3) having a slot-shaped passage opening (4) allowing an outward tilting movement of the fastening screw (8). When applying the annular clip body (1) around a pipe or similar article- (10) causing the two flanges (2,3) to move one towards the other - the screw (8) provisorily threaded into the nut (5) in the auxiliary part (9) carried by the second flange (3) will first - due to the first flange (2) pressing against the head of the screw (7) - tilt outwardly and then tilt back under spring action so that it shank (6) is entering into the slot (4).

Abstract: 2.1. With the device, it shall be possible to achieve an effective extremely fine-grade comminution, i.e. to achieve high degrees of fineness with high power densities, of solids, preferably hard mineral materials, in which case the constructional outlay for this shall be small and an anti-wear protection shall be produced on the moving parts without additional outlay. 2.2. The device consists of an external cylinder 2 which constitutes the grinding vessel and of an internal cylinder 1, an annular grinding gap 4 being constructed between the two. Said device is characterised in that the internal cylinder 1 is fixedly arranged and the external cylinder 2 rotates with a speed of rotation which ensures radial accelerations greater than 740 m/s<2> and in that an annular effective grinding gap 4 is formed between the external and internal cylinder by the deposit 8 of grinding bodies and particles of the material for grinding on the rotating external cylinder 2. 2.3. The device is suitable for extremely fine-grade comminution of solids, preferably of hard mineral materials, and can be used wherever disperse systems are to be produced with particle sizes < 5 mu m. <IMAGE>

Abstract: A process for making lightweight, malleable, high temperature pyrolytic graphite material having uniform AB plane spacing from a dense pyrolytic graphite material by first heating the dense pyrolytic graphite material to a temperature of at least about 2900°C. Thereafter, the pyrolytic graphite material is heated with an intecalating agent at an elevated temperature; the intercalating agent preferably is washed from the treated pyrolytic graphite material; and the (washed) pyrolytic graphite material is heated at a temperature of about 700°C to about 1100°C for a sufficient time to form an expanded pyrolytic graphite material. The product is a stable, low density, non-friable, compressible, heat-graphitized pyrolytic graphite expanded by intercalation in the c direction of the AB plane spacing with remarkable uniformity and has excellent insulation characteristics. It is malleable, or may be rigidized.

Abstract: An improved blood oxygen sensor apparatus having a special leakage compensation circuit (57, 59, 63, 65, 67, 69, 71, 73, 75a-75d, 79) that allows proper initialization of the oxygen sensor (21) regardless of the value of leakage resistance (55) which typically might be present in parallel with the oxygen sensor (21). During an initialization mode, in which a capacitor (51) arranged in parallel with oxygen sensor (21) is charged by a small initialization current, the leakage compensation circuit monitors the capacitor voltage and controllably increases the current if it is determined that the capacitor (50) is charging at an insufficient rate, due to unspecified leakage resistance. This enables the oxygen sensor (20) to be properly initialised such that it can thereafter accurately measure blood oxygen levels.
