Title: Electrolytic cell and process for the labeling of proteins and peptides
Inventor: SCORTICHINI CAREY L
IPC: C25B9/19
Filed: 1992-05-12
Granted: 1999-03-30
Abstract: An electrolytic cell for the labeling of proteins, peptides and other organic molecules employs a cathodic half cell and an anodic half cell, where a porous working electrode is located in one half cell and a counter electrode is located in the other of the half cell, the two half cells being divided by a separator. A reference electrode located in the half cell containing the working electrode, and placed outside the current path between the working electrode and the counter electrode confers precise control of the working electrode potential, which allows the maximum rate of labeling to be achieved while minimizing oxidative damage to the protein, peptide or organic molecules. Saturation of the working electrode with non-radioactive label coupled with a ratio of working electrode surface area to volume of half cell containing the working electrode between 0.001 to 10 cm<-><1> minimizes the problem of loss of activity of radiolabel due to adsorption on the working electrode. <IMAGE>

Abstract: The invention relates to a steel foundry slag aggregate, a process and installation for obtaining the aggregate. The aggregate has a calcium hydroxide content ranging from 2.5 to 7%, 2 ... 4% ferromagntic particles, 18 ... 21 mg/l sulphur and a basic pH ranging from 11.5 to 12. According to the invention, the process starts by abundantly spraying the slag dump with 20 ... 30 l of water, on each square meter, the operation being repeated every 15 ... 20 days and being continued for 5 ... 6 months in order to facilitate the chemical reactions after which all the slag components remain stable. After 8 ... 10 months the aged slag is sorted by successive operations for removing large masses, after each sorting/sieving operation there being aimed at magnetically separating the material rich in iron, existant in the slag. The installation claimed by the invention is provided with bunkers (1 and 11), a metal sensor (13) for detecting the metals and an electrical tackle (14). The displacement of the slag between the equipments is carried out by means of some belt conveyors (4, 6 .... 48) and by means of some vibrator conveyors (3, 7 ... 36), which bring it in front of some electromagnetic separators (8, 18, 23 and 34), being then discharged into crushers (15 and 27) and then sorted.
