Title: Tube for sepn. by centrifugation - is made of synthetic material and contains moving cylindrical separator preventing subsequent remixing
Inventor: BALLIES UWE DR MED
IPC: B01L3/14
Filed: 1977-03-16
Abstract: A tube for the sepn. by centrifuging of the heavier components from the lighter components of a liq. e.g. blood, and preventing subsequent mixing of the components, contains a cylindrical body, the density of which is between that of the components, and the external dia. of which is equal to the internal dia. of the tube. The tube is made of a synthetic material. During the centrifuging, the cylindrical body slides along the tube. The lighter component flows past it in the space formed between the body and the tube by the slight expansion of the tube, so that the body is always at the interface between the heavy and light phases. A suction piston may be attached to the cylindrical body and the tube may have a ferrule for an injection needle so that a sample can be drawn into the tube. The suction piston shaft is removed before centrifuging. Problems associated with excessive friction between glass tubes and plugs of elastomeric material, diffusion of mixt. through filter discs, and complicated methods of introducing the sample are avoided. The appts. is simple to make, e.g. by injection moulding. Mixing or diffusion of dissolved components is prevented, even during transport or prolonged storage. Filling is simpler, partic. when the appts. is used for sampling blood.

Title: Multiple channel collimator for radiological diagnosis - arranged so that each channel can swivel
Inventor: POLLERMANN MAX PROF
IPC: G21K1/02
Filed: 1978-03-07
Abstract: A multiple channel collimator, used for the measurement of the spacial distribution of radiation from radioactive sources, is described. Each measuring device fits into the top of the collimator tube and is surrounded by sufficient lead shielding in the collimator housing to ensure that stray radiation from sources outside the direct field of focus of the collimator is blocked. In order to overcome the limitations imposed on the field of view of each collimator by the necessary mass of shielding, all but one of the collimator housings are in the form of ball joints fitted at the bottom of the unit which enable each collimator to be directed at the desired point on the object to be studied. Multiple channel collimators are of particular value in radiological diagnosis in which the flow of a radioactive substance through an organ such as the heart is analysed. It is impossible to build one multiple channel collimator with parallel collimator tubes to cover the wide variety of shapes and sizes of human organs. The multiple channel collimator described above can be used to analyse the radioactive emission from organs with a wife range of shapes and sizes.

IPC: F22B1/18
Filed: 1978-03-31
Abstract: A steam generator for a gas-cooled nuclear reactor is housed in a lined vault of the pressure vessel and comprises heat exchange surfaces consisting of preheater (economiser), evaporator, superheater and intermediate superheater (reheater) sections. The prheater, evaporator and >=1 superheating zone are formed of helical tube bundles in an outer annulus, while the final superheater zone comprises a vertical, straight tube bundle in the 'core' region of the steam generator within the helix. The gas inlet is in the side of the steam generator. The reheater section is also composed of vertical, straight tubes occupying the annular space below the helix and around the downward projecting final superheater tubes where they extend below the helix. The upper region of these reheater tubes is at the same level as the gas inlet and is encased between an inner cylindrical guide plate or jacket and an outer jacket. The annular space between this outer jacket and the vault liner has a lower boundary composed of an annular (conical) wall and a gap seal extending around the entire circumference, while the upper end of the annular space is bounded by a second gap seal and a curved deflector plate for the incoming coolant gas. Inside the intermediate superheater (reheater) there is a curved bottom deflector plate which guides the hot incoming coolant gas from the reheater into the final superheater in the centre of the vessel. The gas flow around the reheater is improved and a considerable reduction in thermal stresses.
