Patent number: 5928608Abstract: Swimming pool or drinking water is chlorinated by the use of an intermittent spray-type chlorinator assembly. The chlorinator assembly includes a chamber for holding a quantity of solid dry chlorinating chemical, typically in the form of briquettes or pellets.The water spray impacts, abrades, and dissolves the briquettes to a degree, and at a rate which is controlled by the velocity of the spray; the diameter of the support grid; the percentage of open space in, and the thickness of the support grid; and the cyclic timing of the spray. The chemical-water mixture falls into a chamber below the spray and is evacuated therefrom through discharge/check valve assembly to a return line that leads back to the source of the water being chlorinated. The spray duration times and the intervals therebetween can be selectively changed by an attendant.Type: GrantFiled: January 8, 1998Date of Patent: July 27, 1999Assignee: Arch Chemicals Inc.Inventors: Kenneth John Levesque, Richard M.

Patent number: 5875717Abstract: An assembly for producing printing plates from photopolymerizable resins includes an upper fixture assembly and a lower fixture assembly. The upper fixture assembly includes an upper glass plate, and an upper shutter box in which an upper UV light source is located. The upper fixture is mounted on a guide post so that the upper fixture assembly can be raised and lowered relative to a lower fixture assembly. The lower fixture assembly includes a lower light bank table containing a lower UV light source, and a lower glass plate on which the resin layer is cast. A doctor blade is drawn over the resin layer to smooth the latter on the lower glass plate. The resin layer is then exposed to UV light through a print pattern-defining negative so as to selectively harden the resin layer and form a printing plate that is defined by the negative pattern.Type: GrantFiled: December 23, 1997Date of Patent: March 2, 1999Assignee: MacDermid Imaging Technology, IncorporatedInventor: Kenneth M.
