Patent DE-4123287-A1 (DE)
Title: Treatment of silica granulate to remove inclusions - uses hydrofluoric acid mixed with organic acid to reduce dissolution of silica from clean material and increase removal of inclusions
Inventor: KNOF REINHARD
IPC: C01B33/12
Filed: 1991-07-13
Abstract: Crystalline granules of SiO2, with a grain size of less than 5 mm, are treated with a mixt. of hydrofluoric acid and an organic cpd., (pref. an organic acid, which protects the clean surface of the silica granules while inclusions are dissolved). The organic acid used is pref. formic or acetic acid. A pref. mixt. consists of 88 pts. of formic acid and 12 pts. of hydrofluoric acid. USE/ADVANTAGE - The organic cpd. coats those surfaces of silica which are clean by alignment of its OH-gps. This reduces or prevents the surface being attacked by HF and so reduces the dissolution of silica in the cleaning process. This allows the etch reaction to be continued for longer, and so to remove more of the inclusions. The resultant quartz is cleaner, while using less HF and dissolving less silica. In an example, 100 g silicic acid was treated with 240 ml acid mixt. at 90 deg.C for 1 hr. Using a mixt. of 60 ml 40% HF with 180 ml water 81% of the inclusions were removed. Using 60 ml HF mixed with 180 ml glacial acetic acid 85% of inclusions were removed. Using a mixt. of 60 ml HF and 180 ml 100% formic acid 88% of the inclusions were removed.

IPC: F02D41/34
Filed: 1992-09-12
Abstract: A device for identifying the position of a shaft of an internal combustion engine has a generator disk linked with the shaft and having at least one reference mark. The generator disk is scanned by a sensor and the thus obtained output signals are evaluated in a control apparatus.

Title: Driving system for interruption free current supply - using lower battery discharge voltage equal to lower terminal voltage and lower drop between battery and load input
IPC: H02J9/06
Filed: 1992-11-13
Abstract: The method involves driving an electric system for interruption-free current supply to a DC load (10) in telecommunication technology. The thermal power output of the load necessitates use of an air conditioner (8). A mains current supply (1) and a back up supply (3) are provided. The supplied power in the form of a three phase current guarantees a direct current, via a rectifier (6), to the load, with the rated voltage identical to the charge voltage of the battery (e.g. 67 V DC). A battery (9), in the form of an accumulator is connected in parallel as a backup supply for the load. The system is driven by a lower discharge voltage than the battery which equals the lower limit voltage at the terminals of the load plus the voltage drop between the battery clamps and the load input clamps. ADVANTAGE - Battery capacity can be reduced without any adverse effect and so efficiency is increased.
