  • Patent number: 4504894
    Abstract: A lighting unit for indirect illumination of an area. The unit has a reflective surface contoured to direct reflected light rays from a source generally upward at predetermined angles for reflection by a surface above the lighting unit providing a symmetrical lighting pattern over the area to be illuminated. The reflective surface is contoured so as to eliminate glare interference to the area to be illuminated by controlling the angle of emanation of the light rays from the lighting unit.

  • Patent number: 4448707
    Abstract: Material is provided for drying cut plants. The material includes a drying agent providing a basic pH in a solution of at least 11 and having properties of becoming at least partially insoluble at a pH no greater than approximately 13.4. The drying agent has properties of saponifying the wax on the stems as the plant dries and as the pH of the drying agent accordingly increases. The drying agent is selected from a group consisting of the carbonates, phosphates and silicates of at least one of sodium and potassium and a combination of the hydroxides, carbonates and bicarbonates of at least one of sodium and potassium. The drying agent may have a concentration of about 3 to 6 pounds per ton of dried cut plants.

  • Patent number: 4442021
    Abstract: According to this method of corrosion protection a coating comprising an aqueous suspension of 10-99.99% of hydraulic binding agents, preferably cement or mixtures thereof with latent hydraulic additives, and 0.01-10% corrosion inhibitors is applied onto the metallic articles intended to be enclosed in structures. The application of these specific protective slurries is advantageous in that they adhere especially well are force-locked, respectively, to the structures of an inorganic material, specifically to concrete and to the metallic articles.

  • Patent number: 4431563
    Abstract: The corrosion of ferrous metal surfaces in gas conditioning apparatus is inhibited by using a gas conditioning solution such as aqueous alkanolamines which contain thionitrogen compounds such as metal thiocyanates or thioamides. After recycling the gas conditioning solution for a few days, the solution dissolves sufficient amounts of nickel or cobalt or other metals in the equipment to act as a synergist with the thionitrogen compounds. In the event, the equipment does not contain any soluble synergistic metals, these metals may be added to the gas conditioning solution as soluble metal salts. Examples of useful additive metals are cobalt, nickel, calcium, copper, chromium, zinc, tin, aluminum, and magnesium.

  • Patent number: 4431561
    Abstract: A material for reversibly storing hydrogen is formed from a lightweight matrix which is chemically and structurally modified to improve its hydrogen storage properties. The utilization of a material which can be any of a number of different disordered structures makes possible the modification of local order chemical environments of the material to increase hydrogen storage capacity and/or improve absorption and desorption properties. Lightweight modifier elements structurally modify the local chemical environments of the matrix to provide a material having an increased density of storage sites to increase hydrogen storage capacity. Transition and rare earth modifier elements structurally modify the local chemical environments to provide a material with an increased density of catalytically active sites for dissociating hydrogen molecules to increase the rate at which hydrogen absorption and desorption can be accomplished.

  • Patent number: 4424137
    Abstract: Acrylic prepolymer comprising:from 10 to 50% by weight of units derived from at least one alkyl acrylate, the alkyl group having from 4 to 12 carbon atoms,from 30 to 60% by weight of units derived from at least one alkyl methacrylate, the alkyl group having from 1 to 5 carbon atoms, andfrom 10 to 40% by weight of units derived from methyl acrylate.The prepolymer is used to encapsulate photocells, connected to one another by conducting wires and positioned on a support plate, by casting a resin into the space located between the support plate and a second protective plate, the resin being obtained by mixing 100 parts of the acrylic prepolymer, from 0.1 to 4 parts of a vanadium arenesulphonate and from 0.5 to 4 parts of a free-radical initiator, at a temperature between 10.degree. and 70.degree. C. and for a sufficient time to solidify the polymeric resin at the temperature selected.

  • Patent number: 4422950
    Abstract: Effervescent bleach activator granules for use in washing and/or bleaching compositions comprising a bleach activator, a peroxoborate and a binding material are disclosed. Preferred granules include an alkali metal perborate monohydrate, preferably in a proportion at least equal to the amount of the bleach activator. These granules have the advantage that the reduction of mechanical loss when used in washing machines combined with a fast dissolution of and reaction between the bleach activator and the percompound in close proximity at a high local pH should improve the bleach performance, particularly in the low/medium temperature range, to a substantial degree.

  • Patent number: 4419718
    Abstract: The simple switch of a small pocket flashlight consists of a single spring wire conductor extending from the center post positive terminal diagonally downwardly across the insulating body separating the two cells toward the uncovered metal can negative terminal of the other cell. When pressure is applied through the flexible nonconductive flashlight jacket, the wire conductor is brought into contact with the metal can negative terminal of the other cell to close the series circuit through the cells and lamp. In opening and closing the switch, bending of the wire conductor is limited to the portion remote from the positive terminal contact end by a fulcrum formed by a bend in the wire and engaging the insulating body between the two cells.

  • Patent number: 4418377
    Abstract: A meter has a polarizing filter so that only light having a substantially horizontal wave motion is emitted therefrom. The meter is positioned beneath a canopy which prevents light from impinging on the vehicle windshield so that polarized light impinges on the side window where reflection thereof is attenuated due to the angle of incidence thereof. A non reflective surface is located adjacent the side window which adds to the attenuation of the reflected light.
