Patent DE-2156666-A1 (DE)
Title: Hollow semiconductor body prodn - from gas phase compound onto heated mandrel in vacuum chamber
Inventor: DIETZE WOLFGANG DIPL CHEM DR
IPC: C30B25/08
Filed: 1971-11-15
Abstract: To enable long tubes (up to 2m) to be made, with uniform wall thickness, the mandrel is made up of sections screwed together, esp. using externally threaded jointing collars in internally threaded ends of the tubes. The mandrel is heated by passage of electric current through it and to obtain a uniform wall thickness product the temp. distribution along its length must be uniform. For this to be achieved, the dimensioning of the jointing elements is such that the resistance per unit length of the mandrel wall is essentially constant.

Title: Sterilising living cells and viruses by charge sepn - using resonant high frequency magnetic fields
Inventor: HANSCHMANN HORST
IPC: A61L2/08
Filed: 1972-11-02
Abstract: Living cells and viruses can be sterilised by one or two self-induction solenoids which feed a capacitor via an electronic switch, so that high frequency magnetic fields, acting in the same direction, are produced. Capacitance, charge, self-induction and magnetic field intensity and duration are so chosen that a charge sepn. is achieved in all microorganisms. This system is useful for triggering a resonance oscillation in the dipole molecules of water, to decompose viruses and microorganism in the cells. This may provide a way of weakening the ferments of the fermentative respiration of cancer cells.

Title: Saw blade heat treatment process - by heating tooth protruding above quenching fluid level
Inventor: ISHIZAWA TOUSHICHI
IPC: C21D9/24
Filed: 1973-05-17
Abstract: A heat treatment for saws (cross-cut saws, circular saws or bandsaws) uses tanks filled with oil or water in which the saw blades move along continuously or intermittently. The cutting edge of a tooth coincides with the fluid level or protrudes slightly above it. A flame blown against it heats it to hardening temp. followed by quenching when it is moved cut of the flame action into the fluid. This hardens only the cutting edge so that the base of each tooth retains flexibility. The hard layer is thick enough to allow two or three regrinds of the saw teeth. The life of a blade can thereby be lengthened by a factor of 3-20.

Title: Fireproofing mine timbers - by treating with dust-binding pastes contg hygroscopic salts
Inventor: LEWER HANS
IPC: B27K3/12
Filed: 1973-09-07
Abstract: Fireproof impregnation of mine timbers is effected by application of dust-binding pastes conts. hygroscopic salts in a concn. higher than corresponds to the relative humidity of the atmosphere at the point of application. With small thicknesses of timber, the hygroscopic salt concn. in the paste should generally be 2-4 (pref.3)wt.% more than the relative humidity, while the greater thicknesses of timer the concn. should generally be 3-5 (pref. 4)wt.% greater than the relative humidity. When the rate of dust deposn. is 100-200 g./m2/day, the salt concn. should be 1-3 (pref. 2)wt.% more; when dust deposn. is greater than 200 g./m2/day, the salt concn. should be a further 2-4 (pref. 3)wt.% higher. A single application of paste imparts fireproof props. due to absorption of the hygroscopic salts into the interior of the timber and dust-binding props. due to the presence of the moist, hygroscopic salt on the surface of the timber.
