Patent DE-2462312-A1 (DE)
Title: Migraine treatment medicaments - contg. lithium orotate, ergotamine tartrate, caffeine and quinine dihydrochloride
Inventor: NIEPER HANS A DR MED
IPC: A61K31/52
Filed: 1974-03-04
Abstract: Medicaments for treating migraine disorders (migraine, migraine attacks, vasomotor headache, hemicrania) contain lithium crotate as main active ingredient, in combination with ergotamine tartrate, caffeine and quinine dihydrochloride. Lithium orotate is a particularly advantageous compound for administration of lithium because it is highly specifically absorbed into glial regions of the brain and permits much lower lithium doses to be used than is the case with conventional lithium salts. This in turn means that control of serum lithium levels is not necessary when lithium orotate is used.

Title: Increase of viscosity of polylaurolactams - by addn of alkylene carbonates to melted condensed polymers
Inventor: FELDMANN RAINER DR
IPC: C08G69/14
Filed: 1975-03-15
Abstract: Method of increasing the viscosity of polylaurolactams or mixed polyamides contg. is not 40wt.% laurolactam, which have been prepd. by hydrolytic polymsn., in presence of 0.3-1.2wt.% viscosity stabilisers and the usual catalysts, by homogeneous distribution in the melted state of 0.1-5wt.%, pref. 0.5-2wt.%, relative to the polyamide, of an alkylene carbonate. This addn. is not to the monomer or during the polycondensation but to the already condensed polyamide. The quantity of 5wt.% must not be exceeded e.g., 6wt.% results in a crosslinked prod. Alkylene carbonates of the general formula (I): are used in which R1, R2 can be H, alkyl, aryl or arylalkyl radicals. In R1, R2, H can be substd. by halogen, esp. Cl, or -OH, ester or epoxy. The procedure allows an increase of viscosity of polyamides which have been prepd. in the presence of larger quantities of viscosity stabilisers. On further working the polyamides are stable and their mol.wts. do not change.

Title: Indoor tennis shoe for synthetic courts - has sole made of two different materials having high and low friction coefficients
Inventor: MUTSCHER SIEGFRIED
IPC: A43B5/10
Filed: 1975-03-29
Abstract: The indoor tennis shoe is for halls with a textile or synthetic covering, so that the show allows the player the same kind of grip and playing conditions he would experience on an outside court.

Title: Clothes drier with heat pump or refrigerator - using heat generated by condensate precipitation for heating drying air
Inventor: BOECKH PETER VON DIPL PHYS
IPC: D06F58/20
Filed: 1975-06-06
Abstract: Clothers drier uses the heat of condensation from the water evaporated from the wet clothes in a circuit by means of aheat pump or refrigerator. In the example, the evaporator of a refrigerator is used as condensate precipitator (a); the evaporated refrigerant is compressed in the compressor (c), and the resulting hot refrigerant vapour is cooled or condensed in the condenser (b) by the drying air, causing the drying air to become heated. Circulation of drying air is carried out by a fan or suitable plates on the clothes drum. The condensed refrigerant is returned to the evaporator via a pressure reducing valve (d). With a compressor power of 0.5 kW, a heating output of 1.5-3.0 kW is obtained. The cooling output of the condensate precipitator is approx. 0.5 kW lower.

Title: Desulphurisation of waste gases - with vanadium pentoxide catalysed oxidn. stage before wet or dry absorption, gives direct prodn. of gypsum
Inventor: HOELTER HEINZ
IPC: B01D53/86

Title: Performance boost for flying boat turbine - uses compressor wash system to inject water and methanol into combustion chambers
Inventor: KOHLER GOTTFRIED DIPL ING
IPC: F02C3/30
Filed: 1975-11-06
Abstract: The flying-boat turbine performance output is temporarily increased in order for the plane to become airborne by injecting water or a water-methanol mixture into the combustion chambers. The boost equipment consists of a water container, an auxiliary wash medium container, and a third container for the methanol. EAch container has its own separate pump and selector valve, and is connected to the wash system at the compressor intake. An intake valve actuated by same lever enables water or dilute methanol to be injected directly into the combustion chambers. A pressure switch, fitted in the wash injection feed pipe, checks the increased fuel flow on boost drive until the actual boost medium injection takes place.
