Title: "osmophoresis" method - deflects particle movement in electrolyte by superimposed divergent magnetic field
IPC: G01N27/447
Filed: 1971-05-11
Abstract: Osmophoresis which is electrophoresis, in which a magnetic field is superimposed by a diverging angle of pref. about 90 degrees on the electrical field direction applied to the substance soln/suspension in an electrolyte pref. NaCl soln. but may be any ion forming cpd. in H2O, or low C org. liq. Method deviates by specific angles, depending on parameters, the path normally taken by the particles, whether or not they carry an electric charge, giving more effective sepn., and allowing hitherto, impossible sepns, and characterisation by particles size, shape, charge, mol. wt. Prolonged study of immobile particles is possible, by arranging movement parameters to cancel out, conversely liqs may be clarified by rapid movement. Cellular materials, inorg. substances, org. polymers may be so handled, e.g. erithrocytes, Fe2O3, colloidal Aq, quartz polyvinyltoluene, etc.

Title: Strong, seamless a1-alloy flasks - for the conveyance of pressurised gases
Inventor: PETROVCSIK FERENC
IPC: B21D51/24
Filed: 1971-06-16
Abstract: Seamless, strong-walled Al-alloy flasks for the storage and/or transport of pressurised or liquefied gases are based on the well-known Al-Mg-Si alloy. The neck of the cylinder is produced by a multi-stage cold reduction process and heat-treatment is effected in-between the individual drawing stages. An additional heat-treatment phase is conducted for approx. 3 hrs. at 520-550 degrees C at a reducing temp. for the prodn. of the neck section. After being left for half-an-hour there is a 15 hr heat-treatment effected, at a temp. of approx. 160 degrees C. Finally the flask is surface-treated in the usual manner. Ensures good surface quality for the flask and hence prevents the flask from ripping. The superior surface finish removes the necessity for an additional surface-finishing operation to be performed.

Title: Transformer or choke-coil of temple construction-type - whose parts above or below columns have similarly dimensioned recesses
Inventor: SARBACH EWALD DIPL ING
IPC: H01F27/245
Filed: 1974-01-23
Abstract: Each part of the section located above or below a column, which is provided with a winding, has a recess, extending in the longitudinal direction of the column and each of the recesses, viewed in a plane running perpendicularly to the longitudinal axis of the column has a cross-section of such dimensions that the surface-sections of the cross-sections of the column, covered by the individual sheet-metal bundles, are about equal in size. This three-phase transformer or choke-coil avoids uneven distribution of induction and resulting troubles, such as much increased noise, undesirable vibration, caused by differential induction, incomplete magnetic utilisation and increased loss in the saturated parts, leading also to greater occurance of hot-spots.

Title: Fully automatic mechanized corkscrew - splits and discards pieces of cork into receptacle
Inventor: KEMPF MANFRED
IPC: B67B7/04
Filed: 1974-06-24
Abstract: This invention improves on the primitive hand-work needed to disengage the unwanted extracted corks. In this corkscrew, the cork is withdrawn, by a thread which is wound on a cone thick enough at the base to split the cork as it is pulled forward by the screw; the pieces fall into a waste receptacle and at once the corkscrew is ready for further use. In practice, each bottle to be opened is rested on a cradle, which moves slightly under the weight, switching on an electric motor and turning the corkscrew.
