  • Patent number: 4174038
    Abstract: A thinner, less-expensive-to produce, and more easily handled, opaque sheet is formed by coextrusion of two polymeric layers containing relatively low loadings of black pigment around a third layer of polymer which is pigmented at levels higher than would be practical using conventional extrusion processes, rather than a coextrusion procedure. The sheet is an improved product for use in packaging photographic film or like products to be protected from light.

  • Patent number: 4170602
    Abstract: Improved processes and products based on the discovery that metal atoms in complex relationship with complexing agents can be used to moderate the formation of organic salt seed crystals which promote an exceptionally well-ordered acicular growth of organometallic salts such as oxalates of the metal. Some acicular, i.e. needle-like, products have particular utility for being reduced to ferromagnetic metal particles which retain a surprisingly large degree of acicularity and possess extraordinarily favorable properties for use in magnetic recording applications.

  • Patent number: 4146657
    Abstract: Electrically-conductive films of tin oxide are prepared by a novel process utilizing gaseous chemical compounds which react to form a tin-fluorine bond at a temperature which is (1) high enough so that the newly-created tin-fluorine bond-bearing molecule remains in the vapor phase; and (2) low enough so that oxidation of the molecule occurs only after the indicated re-arrangement. Films prepared by the process of the invention are characterized by surface resistances as low as 1 ohm per square when the film thickness is as thin as about a micron. These films are also characterized by extremely good reflectance of infrared radiation.

  • Patent number: 4146504
    Abstract: Novel materials formed from powders of high porosity, usually characterized by high surface area and always with a very low bulk density, are disclosed. Metal-bearing powders of this type are found to be particularly useful as catalysts and in magnetic applications. Some such powders find use in reinforcement of resins. Also disclosed are novel procedures suitable for making such powders and novel processes and novel compositions in which these powders can be advantageously utilized.

  • Patent number: 4144015
    Abstract: An improved combustion process including emulsification of oil and water and conveying the emulsified oil and water, in the presence of some dispersing gas, under pressure into a combustion chamber where the gas aids rapid and excellent atomization of the emulsion.

  • Patent number: 4141964
    Abstract: Process and apparatus for conditioning whole-cell-containing physiological specimens such as those comprising mucous as a thickening agent. The specimen is made homogeneous, i.e. transformed into a single-cell suspension, and reduced markedly in viscosity by repeatedly being forced or sucked into and out of a small and relatively sharp-edged conduit positioned in a sample-holding container.

  • Patent number: 4141461
    Abstract: A secure bottle for storing of pills, or the like, wherein the novel cap member comprises a rotatable member and a stationary member positioned for relative rotation with one another; the rotation being opposed by a biasing means between said members; and the rotation also being opposed by a locking construction engaging the member until the upper member is lifted free thereof.

  • Patent number: 4137361
    Abstract: Novel powders, and resinous compositions bearing said powders, characterized by excellent chemical stability, electrical conductivity, and energy-absorbing characteristics. These three characteristics can be utilized, alone or combination, in forming many novel articles including microwave shielding apparatus, magnetic recording media, explosives, and the like articles. The more advantageous powders are characterized by a very thin coating of an electrically conductive metal carbide, metal silicide, or metal boride upon the surface thereof, and a metal core.

  • Patent number: 4132010
    Abstract: Mobile sand de-oiling apparatus can be transported along beaches to cleanse sand contaminated by oil and other liquid petroleum products washed onto the beach. The contaminated sand is conveyed into one end of the apparatus and deposited as a layer onto a specially constructed inclined laminated perforate tray. The tray osculates vigorously so that the sand is not only conveyed along the tray where it is exposed to a multiplicity of overhead steam jets, but also clumps of sand are bounced up and down with the result that the individual sand particles separate from one another and turn and spin so that their entire surfaces are exposed to the hot steam. The steam thins the oil which is driven from the sand particles by the steam jets through the tray into a sump. The clean sand is discharged from the opposite end of the tray onto a conveyor which transports it to a storage site.

  • Patent number: 4125302
    Abstract: A novel, easy-to-level, wall-supported support member which is particularly useful for support of apparatus requiring a horizontal surface on which to operate properly. Particular advantageous use of the apparatus is as a support for a phonograph turntable. The apparatus is suitable for compact packaging, is easy to mount and easy to assemble from a kit.

  • Patent number: 4120445
    Abstract: An information-bearing article for conveying indicia from one person to a second person in such a way that the information cannot be surreptitiously detected by an intervening person.Thus, the information-bearing means is so constructed that detection thereof necessarily requires some irreparable and detectable disfigurement or mutilation of the information-bearing article. Use of the article in lottery ticket distribution and use in connection with the transfer of highly confidential governmental or business information, are typical applications.The most advantageous construction of the invention combines means to avoid surreptitious detection of the hidden indicia by optical, chemical, thermal and mechanical processes.

  • Patent number: 4120288
    Abstract: An improved solar collector has a one piece monolithic fiberglass frame and back assembly in which all of the collector components are mounted. A mounting flange integral with the frame facilitates securing the collector in place on a roof or other support. The frame has a double wall construction forming internal steps that support the absorber plate and anti-convection cover at the proper locations for maximum heat collection. Further, all fluid connections to and from the absorber plate are made through the frame so that the required plumbing can be brought out in any direction between the frame walls. Suitable insulation is provided in the panel between the absorber plate and the back as well as between the frame walls to minimize radiation losses through the sides and back of the collector.
