Title: Silver recovery from spent photographic solutions
Inventor: KUNDA WASYL
IPC: G03C5/395
Filed: 1989-10-12
Abstract: ABSTRACT OF THE DISCLOSURE      A process is disclosed for recovering silver sulfide from a silver containing spent photographic fixer solution   The process is particularly suited for treating the fixer solution in a manner which enables recycling of the solution and hence considerable reduction in cost in the fixer solution and reducing pollution to the  environment.  The process comprises introducing hydrosulfide into the silver containing spent fixer solution to precipitate silver sulfide.  The precipitate is isolated from the fixer solution to remove thereby silver and hence enable recycle of the fixer solution.

Title: Wood composite forming and curing system
Inventor: CHURCHLAND MARK T
IPC: B27N3/08
Filed: 1990-09-17
Abstract: WOOD COMPOSITE FORMING AND CURING SYSTEM          ABSTRACT OF THE DISCLOSURE      Adhesive coated wood strands are laid up on a conveyor belt and conveyed thereon to a microwave curing press. Due to uneven temperature or moisture profiles of the layup and/or uneven micro-wave deposition patterns in the press, the structure wood products thereby formed in the past had uneven density profiles. This reduces product strength and product properties especially after wetting. Before entering the press the moisture and/or temperature profiles of the layup are controllably altered according to this invention thereby improving the resulting density profiles. Moisture and/or temperature levels of predetermined areas of the mat are increased or decreased to obtain the desired pre-press profiles. The profiles can be adjusted for example by the application of hot steam to the lower mat surface directly or the conveyor belt directly and the mat thereby indirectly, and/or the application of a water spray and cooling fan air to the same or different mat layers.
