Title: Immunological determination and detection procedure - in which immunoactive substances are immobilised on a solid phase before subjecting to the immunological reaction
Inventor: NOELLER HANS-GUENTER DR
IPC: G01N33/545
Filed: 1976-02-21
Abstract: Detection and quantitative determination of immunoactive substances in liquid samples of biological materials comprises immobilisation of the samples (or the substances therein which are to be detected) on a solid phase before carrying out the immunological reaction. The precision and sensitivity of the procedure are higher than those of conventional procedures. Immobilisation of the substance(s) to be determind reduces costs and improves the speed and simplicity of determinations. In determinations of dangerous substances such as hepatitis B antigen, the immobilisation eliminates the risk of exposing laboratory personnel to possible infectious material. In an example the new procedure is applied to the determination of hapatitis B antigen by immunofluorescence assay. The blood sample to be tested is diluted with saline and applied to a synthetic fibre material. After drying, the material is immersed in acetone for 5 mins. to fix the immunoactive substances on the fibre.

Title: Therapeutic ozone generator - is arranged so that blood or similar is circulated to form non-clotting froth with UV radiator selection facility
Inventor: STADTLAENDER HANS DR MED
IPC: A61M1/32
Filed: 1976-05-31
Abstract: Oxygen can be converted into an ozone/oxygen gas mixture in an oxygenizer and used for therapeutic purposes. To treat blood or similar fluids, they are made non-clotting and turned to froth by this mixture. The oxygenizer is used to convert oxygen into an oxygen/ozone mixture. If blood is to be treated, it is filled into the container and an oxygen/ozone mixture is introduced through a connection to produce froth. A silicone hose connected to the outlet directs the fluid through a Vee-shaped quartz tube closed to the u.v. radiator in the socket. The treated blood is collected in another container. If just u.v. treatment without oxygen/ozone is required, the fluid is introduced into another tube close to the radiator.

Title: Continuous rotary mixer esp. for chipboard prodn. - has glue feed nozzles discharging against chips movement to improve mixing
Inventor: OEDIGE WILHELM
IPC: B01F7/00
Filed: 1976-06-04
Abstract: A continuously operating ring mixer is used for introducing liq. into a mass of powdery, fibrous and/or chip-like material, in particular for introducing glue into sawdust, fibres, and/or chips for making fibre-board or chipboard. The appts. comprises a mixing rotor, revolving in a generally cylindrical housing, the solid mixt. being introduced at one end and the liq. (glue) being introduced through a series of nozzles along the length of the housing, penetrating between the mixing blades. The final mixt. is discharged at the opposite end. The outlet of >=1 of the liq. introduction nozzles is open in a direction opposite to the flow direction of the mixt. as it is stirred. In one pref. arrangement, there is a slit parallel to the axis at the end of the tube. In another arrangement (as shown) there is an oblique outlet terminating at about the centre of the end of the nozzle. In yet another arrangement the end of the nozzle is curved over in the region of the slit. As the granular, fibrous or similar material tends to pile up under the action of the mixer blades, on the upstream side of the nozzle, it encounters the discharged liq. and the two substances thus become throughly mixed together. By contrast, there is very little discharge of the liq. glue on the rear face of the nozzle, at which it might not become mixed with solid material and could consequently fall onto the inside of the drum, thus causing an adhering coating.
