Patent number: 6402096Abstract: A plumbing slider bracket and ratchet arm conduit clamp includes a slider bracket with an inner bracket section which is telescopically received within an outer bracket section such that it is slidable back and forth within the outer bracket section to make an extendable slider bracket. Flexible tabs extending from either end of the slider bracket allow attachment of the bracket to an outer stud surface, or within the stud spacing in any desired orientation. Each ratchet arm conduit clamp is received by the slider bracket and is movable along the length of the slider bracket until a conduit is clamped therein. The clamping action both secures the conduit in place within the clamp, and also forces a resilient insert downward against the bottom wall of the slider bracket to anchor the clamp in position within the slider bracket.Type: GrantFiled: October 31, 2000Date of Patent: June 11, 2002Assignee: Sioux Chief Mfg. Co., Inc.Inventors: Joseph P. Ismert, Victor M. Carr, Frank D. Julian, Arthur B. Hicks, Richard D. Thomas

Patent number: 4963366Abstract: According to the invention, a liquid deliquescent composition is substantially uniformly applied to grain, animal feed, animal feed ingredients, hay or poultry litter product, inhibiting moisture migration or translocation in the product and thereby inhibiting the formation of mold-generating accumulations of moisture adjacent the walls of storage containers for grain, animal feed, feed ingredients or hay which are subject to large overnight temperature drops, and similary inhibiting the formation of mold-generating accumulations of moisture adjacent the walls of grain elevators or silos subject to large seasonal temperature drops. Such inhibiting of moisture migration or translocation according to the invention also inhibits the formation of dry zones in grain, animal feed, feed ingredients, hay or poultry litter, thereby inhibiting the generation of dust from such products, including the inhibiting of dust generation during the screw-conveying of grain to storage.Type: GrantFiled: January 23, 1989Date of Patent: October 16, 1990Inventor: Richard D. Thomas

Patent number: 4847067Abstract: A mold and dust inhibiting composition which has particular utility in connection with the storage and handling of animal feeds, grains, and hay, and also in connection with the use of animal litter such as poultry litter, as well as having general utility for controlling both mold and dust. The composition of the invention is an aqueous solution of one or more salts of propionic acid, one or more deliquescent substances, and also preferably one or more humectants. Propionate ions are made available for mold control by this solution just as effectively as propionic acid, but without the disadvantages of propionic acid including a bad odor, serious corrosive characteristics, and high volatility and hence short residual time. The deliquescent, and preferably also the humectant, prevent moisture from migrating toward container walls where there is a large day/night temperature differential, and also prevent dry regions from developing and producing potentially harmful dust.Type: GrantFiled: February 26, 1988Date of Patent: July 11, 1989Inventor: Richard D. Thomas

Patent number: 4835939Abstract: A system for packaging articles within containers, each container being generally egg shaped and having an open end for receiving the articles and having a generally planar closure applied to the open end thereof to confine the articles therein. The system includes a multi-station intermittently rotatable generally circular turret or carousel carrier disk having a plurality of radial slots, each fixedly mounting a canister for receiving and temporarily confining articles therein fed into the top thereof during partial rotation or indexing of said turret or carousel and for receiving an open container fed into the bottom during the remainder of the rotation thereof. These canisters are open at both ends for systematically receiving the articles and containers in timed relation. Highly polished reciprocatable fingers are selectively positioned beneath the canisters when such are located at prescribed locations to confine the articles therein.Type: GrantFiled: January 7, 1988Date of Patent: June 6, 1989Assignee: Sara Lee CorporationInventors: Richard D. Thomas, Cecil R. Bell, Jr.
