Title: Treatment process of a purge solution, particularly used in the electrolytical winning of zinc
Inventor: LAVEYNE MICHEL
IPC: C25C1/16
Filed: 1984-04-18
Granted: 1988-09-01
Abstract: The invention relates to the treatment of purge solutions formed in the process of the extraction of zinc by electrolysis. According to the invention, the purge solution, which consists of a part of the purified solution rich in zinc sulfate, is subjected to electrodialysis in the presence of an anion exchange membrane so that a catholyte is formed which is depleted in zinc and in sulfate and which contains magnesium. The catholyte can then be precipitated by neutralization, after recovery of the remaining zinc. Application to the extraction of zinc from its ores.

Granted: 1989-11-02
Abstract: In a prophylactic method for cleaning and disinfecting a contact lens, the lens is contacted for an extended period, typically up to 10 hours, for example 5 to 10 hours, with a solution containing hydrogen peroxide. The contacting is effected in the presence of a solid sustained release composition which slowly liberates a peroxide inactivator and which maintains its integrity over the extended period. The solid composition liberates sufficient peroxide inactivator such that substantially no peroxide remains in contact with the lens at the end of the extended period. The lens may then be contacted with a contact lens wetting or comfort solution before insertion into the eye.

Abstract: It is a known phenomenon that the web during the drying moment in a paper machine shrinks. The shrinkage in the machine direction can be controlled by arranging the different driving groups in the drying section to operate at different speeds. The shrinkage in cross direction, however, heretofore was not brought under control. The present invention has the object to solve thos problem. 
<??>According to the invention, the problem of shrinkage is solved in that the web during a certain drying interval is subjected to outward directed forces, which are applied during a suitable drying interval and preferably at a low dry content, for example directly after the press section.

Abstract: Electrically powered trolley vehicles in headings of mines are provided with a current collector pick-up unit having contact-sensing means, current collectors, position sensors and guide wheels. The power supply for the pick-up unit comprises an array of elongated guide rails and at least two conductor bars. The connecting method comprises running the vehicle slowly forwards, by means of its own energy source, in the direction of the elongated conductor bars and vertically raising the pick-up unit by means of an arm mounted on the vehicle so that a contact-sensing frame for sensing contact in a vertical direction is brought into engagement with one or both of the guide rails. During a continued vertical movement, the contact-sensing frame is turned down towards the rest of the pick-up unit and when the contact-sensing frame reaches its lower end limit position, this is indicated by a position sensor. The pick-up unit is then turned in the lateral direction until contact-sensing bars for horizontal sensing are brought into engagement with the nearest guide rail. When the position sensors indicate this, the frame is lowered and the pick-up unit with its current collectors and guide wheels is raised towards the conductor array, whereby the current collectors are brought into contact with the conductor bars and the guide wheels are brought into contact with the guide rails.
