Inventia prezinta un proces tehnologic de obtinere a carbonatului de calciu în doua grade de puritate, ambele avansate, procedeu bazat de aplicarea unei metode hidrodinamice de purificare, în cadrul tehnologiei clasice de extragere a varului cu dioxid de carbon, folosind una sau doua faze de hidrociclonare.

Inventia se refera la un procedeu de obtinere a unui sortiment de carbonat de calciu pentru paste de dinti si produse cosmetice. Procedeul prevede tratarea superficiala a carbonatului de calciu de înalta puritate având urmatoarele caracteristici fizico-chimice: CaCO3 99%, grad de alb 97%, particule de maximum 10 miu m cel mult 1%, alcalinitate 0,008%, R2O3 0,15% si aflat în suspensia apoasa de co...

Inventia se refera la un procedeu de obtinere a unei compozitii dezinfectante, prin contactarea într-un mediu apos a unui compus care elibereaza bioxid de clor, cu un acid organic diferit de acidul lactic, ales dintre acidul citric, malic, tartric, glicolic sau mandelic si cu un compus polihidroxilic ales dintre dextroza, xiloza, galactoza, manoza, lactoza, riboza, hidroxietilceluloza, glicerina, ...

The present invention relates to the preparation of sterically hindered substituted N-secondary amino acids by a one-step reductive condensation of an amino acid containing a primary amino group and a ketone thereby to form a mono-substituted amino acid. Also disclosed is a process for preparing the corresponding sterically hindered tertiary amino acids by reacting the mono-substituted amino acids...

The casing may retain batteries of differing size and has an aperture for the battery insertion. The casing (1) dimensions are rated for accepting batteries (62) of the largest type. The inserting aperture can be closed by a lid (5), and a battery holder (1) can be shifted in one of several positions according to the battery size. Thus it forms an appropriate space for the inserted battery betw...

A method of making an electrical device, e.g. a lithium cell wherein protective material is removed from a sensitive material (e.g. lithium strip) during, after, or immediately before, incorporatirg the sensitive material in the device. The protective material (preferably polymer film) may be peeled off the sensitive material or may be dissolved in liquid, preferably a liquid with which it comes i...

A balanced rotary seal assembly for positively adjusting the seal between a rotating shaft such as a hydraulic turbine shaft having rotary components carried thereby and the surrounding non-rotating machine elements wherein the seal assembly includes a plurality of counteracting pressure applying and fluid conduit devices which are radially spcaed about the axis of the shaft so that an adjustable ...

A contact arrangement for a semiconductor device (typically a GTO thyristor), in which a disc-shaped first connector electrically connects one region of the semiconductor element with its associated contact.
