Title: Shaft packing - for converter bearing boxes which ensures a good seal with the bearing journals at all times
Inventor: HOCHREUTER JOHANN
IPC: C21C5/46
Filed: 1971-10-22
Abstract: Radially effective shaft packing for converter bearing boxes used in steelworks is accommodated in an annular space which is formed by a housing cover with an annular recess in front of which an auxiliary cover is fixed. The packing is resiliently pressed against the shaft surface and is surrounded by a slotted metal ring having a cylindrical bore and a conical exterior. This is surrounded by a second ring that is in contact with the external area of the annular space, and this ring is pressed against the first by helical or cup springs along its conical interior. This provides a radial pressure against the packing via the conical inner ring, which can be regulated by thumscrews, which take effect on the hold-down springs.

Title: Proteins immobilization on plastics surfaces - by swelling the surface with a solvent, applying aq-organic protein soln, and evaporating excess solvent
Inventor: AFFONSO ALVARO PROF DR
IPC: G01N33/545
Filed: 1975-03-07
Abstract: Protein cpds. (esp. antigens or antibodies) are immobilised on plastics surfaces by (a) treating the plastics surface with a solvent which does not dissolve but does swell the plastic surface, (b) applying the protein cpd. dissolved in a homogeneous mixt. of water, organic solvent and solubiliser (pref. a surface-active or organic cpd.), (c) subsequently evaporating excess solvent, and (d) drying the plastics surface. The immobilised proteins are useful for diagnostic and other purposes. Thus, when the immobilised protein is human chorionic gonadotrophin antibody or a syphilis-specific antibody the immobilised protein can be used for the immunological diagnosis of pregnancy or syphilis. The need for two liq. phases in diagnostic tests is avoided. Thus tests using antibodies immobilised on plastic foils are carried out by applying a drop of antigen-contg. soln. to the foil; if the test soln. is positive, a white ring appears around the edge of the drop after a short time, and when the test soln. is negative the drop remains clear.
