Title: Sex predetermination in artificial insemination - by separating male and female determinative sperms by electrostatic attraction
Inventor: LANG JOHN L
IPC: A61K35/52
Filed: 1972-11-17
Abstract: The sex of offspring produced by artificial insemination can be determined by the principle that male - determinated sperms are positively charged and female - determinative sperms negatively. The fluid containing live sperms is exposed to the action of a medium which has an electrical charge of one polarity. This fixes preferentially sperms of the opposite charge to this medium and makes them immobile in the fluid. These immobile sperms are flocculated and separated by filtration. They are then made mobile again by separating the sperms from the medium with the opposite electrical charge.

Title: Centrifugal filter with controlled filtration rate - having a static layer of filtrate between the filter medium and the bowl
Inventor: HULTSCH GUENTHER
IPC: B04B11/02

Abstract: Filtrate flows through the filter medium into a holding zone and through outlets at the edge of the bowl. The rotation produced a large hydrostatic head in the holding zone and hence a reduced press. at the surface of the filter medium. This press. can be controlled, e.g. by extending the bowl parallel to the axis and holding a second layer of liq. in the extension whose depth controls the press. at the outlet from the holding zone. By adjusting the depth faster filtration is obtd. or filtration can be slowed or stopped.

Title: Helical spring assembly for electric razor oscillating motor - has distortion at springs most effective points reduced by parallel end surfaces
Inventor: VOIGT GUNTER
IPC: H02K33/02
Filed: 1973-08-28
Abstract: The helical spring assembly for an electric razor oscillating motor consists of two helical springs mounted on each side of the pivoted armature shaft. The locating surfaces for the springs ends on the housing and on the armature are arranged so that they are parallel to one another in pairs when the armature is in its spring-loaded position, and at an angle to one another in pairs when the armature is in its central, unloaded position. When the armature is pivoted to the right, the two right-hand surfaces on the armature and housing are parallel; and when pivoted to the left, the two left-hand side surfaces are parallel. Aligning the surfaces in this way reduces distortion in the springs at the point where they are most effective.

Title: Suspended wall bracket for fixing furniture to walls - has holder fitment with screw markings at one end for easier adjustment in bracket
Inventor: WILKE JUERGEN
IPC: A47B95/00
Filed: 1974-02-06
Abstract: The suspended wall bracket for fixing furniture items to walls comprises a holder fitment which is adapted to be adjusted in height and/or length by means of a screw bolt or bolts which interact with a thread and move up and down and/or along in guide housing and are designed as an integral part of the holder fitment which is made of a solid section. The fitment is preferably of a basic T-section with the suspension element at one free end and the screw bolt at another free end. The screw bolts themselves are simply formed by cutting a thread at one or two free ends of the fitment and in order to displace the latter interact with an adjustment nut or the like which is accessible from outside the guide housing. The wall bracket can thereby withstand great strain during use and can be manufactured and assembled more economically.
