Patent number: 5395703Abstract: Various metal coatings have been used for many years to inhibit oxidation of metals exposed to the natural elements of the atmosphere over a period of time. Terne alloy coatings which normally contain about 20% tin and about 80% lead are some of the most popular metal coating treatments to resist corrosion. The special formulation of the present invention reformulates the terne coating to constitute a tin and lead based coating where tin constitutes at least 90% of the terne and lead amounts to less than 0.1% and preferably less than 0.05% of the terne. The low lead terne coating may also include antimony and bismuth to provide strength and hardness to the low lead terne formulation having corrosion resistive qualities similar to that of standard terne coating formulations.Type: GrantFiled: November 17, 1993Date of Patent: March 7, 1995Assignee: The Louis Berkman CompanyInventors: Jay F.

Patent number: 5061022Abstract: A door closure arrangement is provided for a paint cabinet or like enclosure containing combustible materials. Right and left hand doors are hinged to door jambs in the cabinet's opening and an overlapping lip is provided on one of the doors to insure that no gap between the doors exists when the doors are closed. Door closures, held in an open position by temperature sensitive fusible links, rotate the doors from an open to a closed position should a fire melt the fusible links. A spring biased, lever actuated door sequencing mechanism insures that the doors closed in proper sequence without interference from the overlapping lip. A spring biased, lever actuated mechanism automatically latches or locks the doors when they are rotated into the closed position whereby the adverse effects of the fire on the contents of the cabinet are minimized.Type: GrantFiled: June 11, 1990Date of Patent: October 29, 1991Assignee: The Louis Berkman CompanyInventor: Jon D.
