Title: Mixing chamber - for dilution and haemolysis of blood free from air bubbles
Inventor: STILLER SIEGFRIED DIPL PHYS
IPC: G01N33/483
Filed: 1990-06-02
Abstract: A mixing chamber is used to mix a very small blood flow of 0.1 millilitre per hr. with a diluting medium (0.5% NH3) at a rate of 1:200 by merging the streams of blood and of medium in a special way. The blood is made to leave its supply line in contact with a drop formed by the medium. The mixt. falls in drops on a plate 1 cm. below the merger and with semi-circular holes in its periphery, leading to a stirring chamber. A magnetic stirrer acts in it before the fluid reaches the photometer. The supply lines for blood and diluent and the lid of the chamber are thrown away after one use, but the rest can be re-used. ADVANTAGE - This guarantees a homogeneous mixt. The plate prevents the entrainment of air bubbles.

Patent DE-4041127-A1 (DE)
Inventor: KRUTZSCH BERND DR
IPC: C10L1/189
Filed: 1990-12-21
Abstract: A diesel fuel containing an additive, which improves soot burning, for reducing the pollutant emissions of the combustion exhaust gases of diesel engines by discontinuous burning-off of soot which has been deposited on the exhaust gas filter is described. For this purpose, a lithium salt, sodium salt or potassium salt of an aliphatic or aromatic alcohol, of a phenol, of an aliphatic acid or a naphthoic acid, of phenylacetic acid or of cinnamic acid, individually or as a mixture, is added to the diesel fuel before the latter is burned in the internal combustion engine. As a result of the addition of the alkali metal salts, the ignition temperature of the soot deposited in the particle filter is reduced and the soot is oxidised at a temperature which is considerably lower than the normal ignition temperature. The regeneration range for the particle filter is thereby much more frequently reached in real driving practice. As a result, a critical filter loading with soot, which can cause filter damage on burning-off, is avoided. A further advantage of the process described is that, according to present knowledge, no additional substances injurious to health are emitted during running as a result of the addition of these alkali metal salts to the diesel fuel. <IMAGE>

Filed: 1991-08-16
Abstract: The drive hub for a vehicle, in particular for a bicycle, comprises a hub axle 1, a hub sheath 9 which can be rotated relative thereto and a driver 13 which is mounted on the hub axle 1. The driver 13 drives the hub sheath 9 via a ball-and-socket friction gear 17 whose ball carrier discs 25 and 27 form, with the hub axle 1, a rigid gear box whose balls 35 are involved in frictional engagement with a guide ring 33, a drive ring 51 and a drive ring 55, which engagement permits different speeds of revolution by swivelling the axle pins 37 between drive ring 51 and drive ring 55. The contact forces are produced by a thread 47 between driver 13 and drive sheath 49 in proportion to the drive torque, the compression spring 57 guaranteeing a response of the ball-socket friction gear 17 which is free of dead-centre points. The continuously variable transmission ratio of the ball-socket friction gear 17 is controlled through a fixed cone 29 via a control device 79 consisting of rotational elements which cause a link wheel 91 to rotate, as a result of which the helical guide grooves 95 move the ball projections 39 of the ball axles 37 radially outwards or inwards depending on the direction of rotation. The ball axles which are swivelled in this way ensure a continuously variable transmission ratio between drive ring and output ring. <IMAGE>
