  • Patent number: 4022464
    Abstract: A package is provided having a rotatable closure equipped with dispensing orifices. The orifices overlie a neck portion having indentations spaced about its inner edge and which when aligned with the dispensing orifices provide access to the contents of the package. The closure includes an inner annular skirt which has axial slots about its outer periphery. The slots direct the flow of the container contents through the neck indentations and out the orifices when the closure is rotated to an open position. When the closure is in a closed position, the orifices will be located above flat areas on the top edge of the container neck.The closure includes a downwardly depending inner wall having engagement means for rotatably connecting the closure to the container neck.

  • Patent number: 4022638
    Abstract: A procedure and apparatus are shown for on a continuous, commercially practical basis recovering a non-ferrous base metal, such as copper or aluminum in the form of clean, bright metal pieces or bits and for enabling recovery of different non-ferrous coating metals, such as of lead, tin or alloys thereof, and under conditions in which a resin insulating coating may be present. Mechanical shredding means is used for reducing insulated wire to an aggregate containing bits, particles or pieces within a requisite size range, extraneous magnetics are removed, and the content of resin coating material is reduced under dry conditions to within a maximum of 2%.

  • Patent number: 4011672
    Abstract: A mounting frame positionable on a rigid surface as desk, table or the like, and adapted to mount photographs, decorative articles, a calendar or the like. This frame comprises triangular-like shaped end walls, a first side wall connecting the end walls, a second side wall substantially parallel to the first side wall and extending between and connecting the end walls. An additional central wall extends between and is attached to the end walls and is located between the two side walls. A clear sheet of flexible plastic material, or a clear sheet of plastic material having certain areas masked off to provide clear openings in the plastic sheet, is inserted between the end and side walls and flexed inwardly against the central wall so that the sheet has a concave configuration. This concave configuration substantially matches the top edge of the end walls which have a concave configuration.

  • Patent number: 4010872
    Abstract: Packages are described wherein two compositions are maintained isolated from each other within a container, the first composition comprising an oxidation hair dye and the other comprising hydrogen peroxide. The container is fitted with valve means which communicate with each composition, actuation of the valve means resulting in mixing of portions of each composition and dispensing of the mixture as a hair dye. Through the addition of a reducing agent or a hydrogen peroxide decomposition catalyst to the first composition, the hair dye can be dispensed in a warmed state. A process for packaging of plural fluids to insure uniform dispensing in which one is a foamable liquid is described wherein the foamable liquid is placed within an inner compartment within a container separated from the remainder of the container by a movable wall and a pressurized fluid is placed inside the container outside the inner compartment.

  • Patent number: 4008526
    Abstract: A toy comprising a hollow body member having a plurality of differently configurated openings and a plurality of block members corresponding in cross-sectional configuration to the openings. In a preferred embodiment the hollow body member is formed as two halves joined together by a spring means which permits the member to be "broken apart" to release the individual pieces. The holes in the hollow body member are located on plane defining portions which are in turn located adjacent curvilinear surface portions of said hollow body member. The block members can be used individually as molds or foodstuff cutters, stacking blocks, etc.

  • Patent number: 4008049
    Abstract: In apparatus for polymerizing high-pressure ethylene to produce polyethylene, a tubular reactor is connected to a source of high pressure ethylene. An intensifier supplies an initiator solution to the tubular reactor. This solution includes one or more catalysts which promote the polymerization reaction. Within the tubular reactor, a peak temperature occurs in proximity of the point at which the catalysts are introduced. If the catalysts are introduced at more than one point, peak temperatures will result downstream of each of such points. For various reasons, the peak temperatures are displaced along the tubular reactor and a plurality of thermocouples are distributed at spaced positions in the tubular reactor to measure the temperatures at the positions at which the peak temperature might occur.

  • Patent number: 4008401
    Abstract: A system for successively curing resinous printing or coatings about the exterior of tubular articles with ultraviolet radiation. A housing is provided having inlet and outlet openings for an endless chain having transversely extending stationary pins. The chain is directed by guide rollers over a sprocket wheel located concentric with an elongated ultraviolet lamp. The axis of the lamp and pins extend parallel to each other so that when the tubular articles are placed on the pins and conveyed around the wheel, a major portion of all the U.V. radiation emitted is utilized for curing and all surfaces of the tube exterior are exposed. The efficiency of the system is further enhanced with the use of a radiation reflector shield positioned radially outward from the sprocket wheel. The system includes a cooling means to remove heat from the housing generated by the ultraviolet lamp.
