Abstract: A process for electroplating metals in an electroplating bath having an anode and a cathode. The cathode is formed by a workpiece to be plated and the anode includes soluble material in the form of the metal to be plated and insoluble material in a proportion selected so that the anode efficiency equals the cathode efficiency. This avoids metal salt build-up in the bath. Metal salt solution carried out of the bath with the workpiece is recovered and recycled to the bath, avoiding loss of metal to the system and waste disposal problems.

Abstract: PCT No. PCT/CH88/00177 Sec. 371 Date Jun. 2, 1989 Sec. 102(e) Date Jun. 2, 1989 PCT Filed Sep. 30, 1988 PCT Pub. No. WO89/02708 PCT Pub. Date Apr. 6, 1989.A process for clarifying raw juice in which the proportion of solids in the retentate circuit (2, 3, 4) of an ultrafiltration or microfiltration device (1) is sharply increased during the starting time (FIG. 1). With increasing proportion of solids, the filtration yield falls off sharply and then increases again to a value which is higher than the starting value. On reaching the maximum possible filtration yield value, the proportion of solids and thereby also the filtration yield is maintained constant by regulating the amount of retentate outflow or the amount of fresh juice to be fed in. In this way the filtration yield can be significantly improved.

Patent EP-0381706-B1 (EP)
Inventor: CURTISS RAY III
IPC: C12N15/09
Filed: 1988-10-06
Granted: 1995-04-26
Abstract: The invention encompasses methods of maintaining desired recombinant genes in a genetic population of cells expressing the recombinant gene. The methods utilize mutant cells which are characterized by a lack of a functioning native gene encoding an enzyme which is essential for cell survival, wherein this enzyme catalyzes a step in the biosynthesis of an essential cell wall structural component and the presence of a first recombinant gene encoding an enzyme which is a functional replacement for the native enzyme, wherein the first recombinant gene cannot replace the defective chromosomal gene. The first recombinant gene is structurally linked to a second recombinant gene encoding a desired product. Loss of the first recombinant gene causes the cells to lyse when the cells are in an environment where a product due to the expression of the first recombinant gene is absent. The invention also encompasses methods of creating and isolating mutant cells with the above characteristics. The cells of the invention are useful for commercial production of desired products, for components of vaccines for immunizing individuals, and for release into the environment.
