Patent number: 11793156Abstract: A method for preparing an ammonia abatement additive for poultry litter that is formulated to assure activation in an interior environment having various relative humidity conditions. The method includes obtaining a blended litter amendment composition that, based on weight, is about 40% deliquescent salt and about 60% aluminum sulfate, relative to a total weight of the two components. The composition can be made by the user or received, already blended, from a third party. To this blended composition that has been obtained, additional deliquescent salt is added in an amount such that the total amount of deliquescent salt is effective to activate the alum-containing ammonia abatement additive at the targeted low relative humidity condition in the interior of a poultry house. The composition is a sub-component of the ammonia abatement additive which may or may not contain additional compounds. The specified relative proportions (i.e.Type: GrantFiled: April 12, 2021Date of Patent: October 24, 2023Assignee: Chemtrade Chemicals US LLCInventor: Rex A. Johns

Patent number: 8020687Abstract: An apparatus is used to enhance the standing-surfaces of platform-components of an escalator or a moving walkway which moves in a continuous loop. The apparatus is maintained in a constant position relative to the moving parts of the escalator or walkway such that, while in that constant position, all the standing-surfaces continually pass under the apparatus as a result of the continuous loop of the escalator. When the escalator is in operation, an applicator-means of the apparatus applies a flowable enhancement-material, in situ, to the standing-surfaces of the moving platform-components. The material solidifies thereon to enhance the surface characteristics of the standing-surfaces of the escalator, or moving walkway as the case may be.Type: GrantFiled: December 3, 2008Date of Patent: September 20, 2011Inventor: Rex John Sutherland

Patent number: 6113077Abstract: Offset racing rail arrangements (16) of the fixed and relocatable variety are made safer by fitment of a cover designed to prevent riders from falling between and sometimes onto the poles which support the racing rail. A cover (22) is provided which is releasably attachable to a receptacle portion of the rail which is also resiliently spaced by a support means from the posts (10) which support the rail. The cover (22) is one embodiment comprises sheet material (24) bent (30, 32, 34, 36 and 38) underneath itself in such a manner as to provide a resilient self supporting spacing from each posts (10). The cover (22) is also in the embodiment provided with an edge portion (26) adapted to releasbly attach to a receptacle portion (56) of the rail without the use of fasteners.Type: GrantFiled: June 11, 1998Date of Patent: September 5, 2000Assignee: Aclis Pty LtdInventors: Rex John Fargher, Barrie Gilbert Woodhouse

Patent number: 3982233Abstract: A three wire 3D core memory which utilizes the same balanced pairs of sense-inhibit conductors to conduct both high energy common mode inhibit currents and low energy differential mode core switching signals includes pairs of antiparallel Schottky diodes interconnecting the conductor pairs at symmetrical positions therealong intermediate the cores of each memory mat. As high energy common mode inhibit currents are generated small deviations from perfect symmetry of electrical characteristics along the sense-inhibit conductors results in the appearance of differential voltages which are substantial in comparison to switching signal voltages. The sense-inhibit recovery time required for dissipation of these spurious differential voltage signals before a memory read cycle can proceed consumes a substantial portion of a memory cycle for large stacks.Type: GrantFiled: February 19, 1974Date of Patent: September 21, 1976Assignee: Ampex CorporationInventor: Rex John Crookshanks
