  • 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.

  • Patent number: 4007900
    Abstract: A thin resilient plastic preform is provided for suspending a shampoo tube or the like having an elongated bottom sealing flange from a hook, showerhead, or faucet handle. The preform includes a tube attachment portion and a hanger portion. The hanger portion is adapted to engage conveniently located objects protruding from the shower wall and can comprise intersecting slits or a cut-out area in the plastic or a handle means. The tube attachment portion is an elongated straight cut through the plastic having a length about equal to the tube body width, but less than the length of the tube bottom sealing flange.

  • Patent number: 4005798
    Abstract: A support block is affixed to the sidewall of a cooking utensil cover. The block is provided with a slot across its outer face adapted to engage the top rim of the utensil. The slot is oriented in the block to cause the cover to assume an approximate upright position over the utensil when the slot is engaged with the utensil rim.
