Abstract: A clock regenerator is designed as a phase locked loop (PLL) and comprises a phase detector (DET) which compares the phase of the input signal (Sp) with that of the output signal (Sa), the frequency of the phase detector being approximately N times smaller than the oscillator frequency. In the phase detector (DET), there are obtained from a regenerated output signal (Sa) two signals delayed by L/N periods, wherein L is a small integer, in order to form therefrom a pulse window comprising at least three zones. The clock regenerator comprises a loop filter (FIL) with a counter, the status of which is recorded in a logic circuit which controls a programmable divisor (DIV) in such a way that when the edges of the input pulse (Sp) fall in the central most zone, the counter counts toward zero and no correction is brought about.

Abstract: A system and method for controlling atmospheric emission of volatile materials such as solvents, used to clean or treat articles incident to their manufacture comprising a treatment chamber and a recirculating closed loop gas and solvent recovery system. The chamber is isolated from the closed loop system, the article to be treated is put into the chamber, the chamber is sealed and gases removed by evacuation, these gases being discharged outside the closed loop system. The articles are treated with solvent, dried with a fluid derived in the solvent recovery system from noncondensable gas, residual in the system. Drying is effected by passing the recovered gases from the closed loop system through the chamber and by evacuation. The gas evacuated from the chamber, containing solvent vapor is retained within the closed loop system. The chamber is vented to outside the closed loop system prior to removing the treated item.

Date Mar. 16, 1995In a method for manufacturing silica a leaching of natural silicates is performed with hydrochloric acid or other mineral acids, draining, drying and possibly a grinding up of the residue of the product obtained. In order to obtain a spherical silica with a controlled particle size and surface characteristics a mineral olivine with the highest possible degree of purity is employed as the basic material. This raw material is reduced to a grain size between 0.05 and 5 mm. The particles are pretreated and washed for the removal of dust on the grain surfaces and heavy materials such as spinel and at least a part of the foliar and stem-like minerals such as serpentine, talc and pyroxene are removed. The olivine particles are then leached in a controlled leaching process where the acid concentration, leaching temperature and leaching time are controlled in order to achieve the desired primary particle size, specific surface and pore volume measured according to the BET method on the extracted silica. The particle agglomerate of spherical particles thus formed with a grain size between 30 and 70 nanometers are washed and dried in the conventional manner, whereupon the agglomerate is divided into the spherical particles.
