Patent DE-2640815-A1 (DE)
Inventor: SAKUMA TADASHI
IPC: G04C3/14
Filed: 1976-09-10
Abstract: A small sized electric timepiece movement has a radius which is less than the diameter of the battery which powers the movement. Hence, the battery extends from one side of the movement to a point beyond the centerline of the timepiece. Advantage is taken of the fact that the battery is dome-shaped so as to accommodate a portion of the base plate which rotatably supports the cannon pinion and hour wheel of the timepiece movement which are located centrally of the timepiece. Hence, the axis of the cannon pinion and hour wheel, if projected, would intersect the battery. The invention enables the construction of an electronic timepiece which is smaller than would otherwise be possible. With a battery having a diameter of 7.9 mm and a thickness of 3.5 mm, it is possible to make a timepiece having a diameter of 14.8 mm and a thickness of about 4 mm.

Inventor: NITELEA ION DIPL ING
IPC: C07D498/08
Filed: 1977-06-27
Abstract: New water-soluble rifamycins are cpds. of formula R.An (where R is the molecule of the hydrazone, arylhydrazone or oxime of rifamycin SV A is the molecule of the alkaline salt of 1-16C straight-chain or brached aliphatic organic acid, an opt. nuclear-substd. aromatic acid, or an acid with steroid structure; and n = 0.5-5). (I) are amorphous or macrocrystalline, orange to dark red/brown substances which are very soluble inhalogenated hydrocarbons, soluble in water and lower aliphatic alcohols, and poorly soluble in aliphatic hydrocarbons. Rifamycin derivs. have antibacterial (esp. antitubercular), antiviral, immunosuppressant and antileukaemic activity. The solubility properties of (I) means that in testing, solvents such as dimethyl sulphoxide or detergents are not needed, so that falsification of results due to solvent or detergents are avoided. In therapeutic nitrations, the good solubility properties reduces the risk of liver damage arising from hepato-biliary circulation of the zifamycin deriv.

Title: Multi-fuel free-piston reaction turbine - prepares fuel externally with air surplus for preheating and compression
Inventor: KOELLNER EDUARD
IPC: F02C5/08
Filed: 1977-08-31
Abstract: The multi-fuel free-piston reaction turbine has a free-piston gasifier which can be instantly changed over between different fuel-air mixtures prepared outside with a considerable amount of surplus air. The mixture, after pre-heating, flows into alternate combustion chambers under the control of slide valves, where it is compressed by a double-acting piston and a variable balance weight fixed to it to ignition point. It then flows outwards through a hollow reaction turbine mounted centrally on the free-piston cylinder. Fuels such as gas, oil or powdery combustible material are prepared in a unit outside the gasifier with a considerable air surplus, to give high ignition temperatures and combustion with low toxicity. After pre-heating in a tubular control slide valve they are directed into the gasifier, where they are compressed by a free piston of variable effective mass, and thus variable stroke and compression ratio, and ignited by self-ignition.
