Title: Phenol resins for improving wet-fastenss of - dyed polyamides
Inventor: MEISTER MARTIN DR
IPC: C08G8/36
Filed: 1969-12-20

Patent DE-2250000-A1 (DE)
Title: Separator for granular material - producing counterflowing heavy and light fractions for purer separation
Inventor: KAISER FRITZ
IPC: B03B5/46
Filed: 1972-10-12
Abstract: Light and heavy fractions travel in opposite directions in a fluidised bed and are removed at opp. ends of the separator, the heavy fraction pref. being transported by >=1 screw conveyors and both fractions being circulated in the bed. The circulation is pref. caused by the conveyors having a varying conveying power along their lengths and by the bottom of the bed being trough-like with perforations for fluidising medium at the top of the trough near the light fraction outlet and at the bottom of the trough near the heavy fraction outlet. This arrangement gives a purer separation of the fractions so that materials with small density differences can be efficiently separated e.g. copper from insulated cable scrap.
Patent DE-2304798-A1 (DE)
Title: Marinade prodn. by addition of dried vegetables - to absorb natural juice of the basic foodstuff and to prevent loss of valuable nutritive substances
Inventor: HENNING WOLFGANG
IPC: A23B4/023
Filed: 1973-02-01
Abstract: Marinade is produced by mixing a cleaned raw foodstuff (meat, fish, vegetables; comminuted if necessary) with a soln contg an edible acid and common salt (pref. 8-12% acetic acid and 15-20% NaCl) in such an amt that dried vegetables (onions, carrots, etc) added in an amt of 6-10% (w.r.t. the basic foodstuff) ultimately absorb most of the free liquid. Thus, the final product contains very little free liquid (in the conventional pickling process, a considerable part of the pickling soln is discarded or not consumed). The conditions of the processing are mild, (with no heating).
Patent DE-2310252-A1 (DE)
Title: Flame resistant polyvinyl chloride - obtd. by adding cyano and amino group-contg cpd
Inventor: BEHNCKE HERMANN DR
IPC: C08K5/16
Filed: 1973-03-01
Abstract: Flat PVC structures (e. g. foils or films) whose flammability depends on the relatively easy HCl decomposition of PVC in the warm, are made flame resistant by causing the HCl being split off to form a chemical cpd. and thus preventing its escape. Flame-resistant PVC foils and films can be used as wood-imitative covering for building material. The process is pref. effected by adding to the PVC before the forming of the foil or film a cpd. which easily reacts with the split off HCl to form a non-volatile cpd. which itself forms with the PVC residue molecule a new molecular complex having a high N content. Suitable cpds. to be added contain both CN and NH2 gps., eg. calcium cycanamide, dicyandiamide, melamine or polycyanamides.

Title: Vehicle fuel saving brake transmission - has fly wheel connected by variable ratio transmission to absorb braking kinetic energy
Inventor: WERNICKE JOACHIM DR ING
IPC: B60K6/10
Filed: 1973-06-22
Abstract: When starting the vehicle an engine speed controlled centrifugal clutch connects the flywheel to the engine, the correct energy balance during driving is maintained by an energy balance unit. In a further variation, the drive shaft powers a generator which charges electrical batteries, during standing periods a coaxially mounted auxiliary electric motor maintains a high flywheel speed so that when starting the increase in engine revolutions reconnects the flywheel to the engine via the clutch and hence reuses energy which would otherwise have been absorbed by the vehicle.

There are further elements with several openings whose cross-section is less than that of the passages.

Patent DE-2401488-A1 (DE)
Title: Pulsating deuterium-lithium 6 fusion reactor - based on reactions occurring in electrically induced plasma path
Inventor: FISCHER ALBERT GEORGE PROF DR
IPC: G21B1/03
Filed: 1974-01-12
Abstract: Pulsating nuclear reactor is proposed (admittedly, the invention has not been checked experimentally as yet) in which energy is liberated by fusion of Li6 and D along a plasma path created in molten Li6D1-xTx (0  x 0.5) by a momentary electric discharge produced by a coaxially placed cylindrical condenser. The plasma path is magnetically self-constricted. Within the path, a nuclear microexplosion takes place. The most important reactions are n + Li6 right arrow T + alpha + 4.8 MeV and T + D right arrow n + alpha + 17.6 MeV, the net result being conversion of Li6 and D into He. Doping with Be can be applied to multiply the number of the neutrons. The neutrons which escape from the plasma path react with Li6DT producing more T. The microexplosion is self-extinguished by the melt flooding the plasma path. Macro explosion is prevented because the chain reaction can proceed only along the filamentary plasma path and cannot spread radially. The molten Li6D1-xTx pool is surrounded by frozen LiD (which can be partly replaced by the cheaper LiH), in which a cooling coil contg. liquid Li is placed. Liquid Li transfers the heat produced by the nuclear reactions to a turbogenerator producing electric energy. The nuclear fusion reaction can be effectively controlled in time (pulses) and in space (restriction to a filamentary plasma path).

Title: Crystals grown from hydrothermal solns - in autoclave with separate individually temp-controlled double walled sections
Inventor: BUTUSOW WLADIMIR PETROWITSCH
IPC: C30B7/10
Filed: 1974-01-17
Abstract: A device for growing crystals from hydrothermal solutions comprises an elongated, vertical autoclave with crystallisation zone at the top and dissolving zone below, surrounded by thermal insulation, heating elements and a thermostatically controlled chamber. This thermostatically controlled chamber is subdivided in its height into a number of sections, each having its separate heating and control system, thus enabling constant but different temps. to be maintained in the sections for the desired uniform temp. fields in the crystallisation zone and dissolving zone. Preferably, the sections comprise double walls with the heaters and thermostatic control devices in the space between. In particular, one special section constitutes the upper lid of the autoclave and thus ensures reliable temp. maintenance in this region. The method is used for the production of high quality crystals, in particular of piezo-optical quartz, on a commercial scale.
