Title: Magnet motor generates power from combined magnetic poles - and wheel with angled magnetic elements
Inventor: OVERSBERG MICHAEL PETRUS
IPC: H02K53/00
Filed: 1974-01-09
Abstract: The magnet motor generates power from combined magnetic parts and magnetic wheels and can be used where normal motors are currently used. Electromagnets or plane magnets are mounted at an angle onto a weakly magnetic or non-magnetic wheel. The opposing poles are mounted on a holder (e.g. a wheel) so that their faces are towards the wheel magnetic elements. The electromagnets are excited at regular intervals so that the wheel is rotated by alternate attraction and repulsion. The motor requires less energy than similar existing types.

Title: Decorative glazes contg. cerium dioxide - contaminated with other rare earth elements
Inventor: KERSTAN WALTER
IPC: C03C8/14
Filed: 1974-03-02
Abstract: Decorative glazes are formed on ceramics, glass or enamels using compsns contg. cerium dioxide which may contain up to 30% (pref. up to 15%) of other rare earth elements as impurities. The latter can also be added in the pure state along with other metal oxides. Decoration of wall- and floor-tiles, ceramic facade panels, earthenware, glass articles, etc. CeO2 is an excellent opacifying agent, which does not need much purification (for this reason, its use is more economic than SnO2 which cannot be used in compsns of this type but in very pure state). The rare earth elements gives in combination with heavy metal oxide very interesting colouration.

Patent DE-2503921-A1 (DE)
Title: DL-Homocysteine prodn. from its alkali salts - by treating with formic acid
Inventor: WAGNER HANS DR
Filed: 1975-01-31
Abstract: is produced from its alkali salts by treating the salts with formic acid. The homocysteine alkali salt is pref. one obtained by demethylation of methionine by means of an alkali metal in ammonia. Homocysteine can be used as a food additive in place of cysteine (partic. since it is easier to produce than cysteine when it is obtd. from methionine as starting material). Homocysteine can also be used in hair cosmetics in place of thioglycollic acid (with the advantage that it is less malodorous and better tolerated by the skin than thioglycollic acid). Treatment of the homocysteine alkali salt with formic acid does not lead to the formation of homocysteine thiolactone, thus simplifying the preparation of DL-homocysteine from methionine. DL-Cysteine is obtained in high yield, and the purity is at least 97% (sufficiently pure for all usual purposes and giving excellent stability on storage).
Patent DE-2508951-A1 (DE)
Title: Hand-held hair dryer with brush attachment - has air outlets providing inclined air flow to brush for quicker drying
Inventor: LIEDTKE DIETER WALTER
IPC: A45D20/50
Filed: 1975-03-01
Abstract: The hand-held hair dryer unit is provided with a comb or brush element (10) with one or more rows of prongs or bristles (20) and a hot air flow which is supplied by the apparatus to the outlet orifices which are designed as nozzles (22) whose flow direction differs from the direction of the prongs or bristles (20). These nozzles are preferably mounted in the base member (12) of the element attached to the dryer (14) and are inclined to the bristles. In this way the hot air does not beat down so strongly onto the top hair layer but allows a more rapid drying by providing some air circulation through the hair as it is being combed or brushed.

Title: Pure water from water contg. foreign matter - controlled vapourisation and condensation, hot water stored in adiabatic vessel
Inventor: LOBSCHAT HELMUT G
IPC: C02F1/14
Filed: 1975-04-25
Abstract: Pure water is obtd from water contg. foreign matter by means of controlled vapourisation and condensation by feeding the raw water heated to 60 to 80 degrees C into an as adiabatic as possible reservoir, where it is stored. After a sufficient fall in temp. between the stored hot water and the condensation surfaces of the installation, the hot water is transfer ed to the chamber serving both as vapouriser and condenser in which the hot water flows as a turbulent film, across the vaporising surface. Alternatively, the hot water may be sprayed in such a way that it does not contact the condensation surfaces directly. An uncomplicated apparatus requiring much less energy.
