  • Patent number: 5189825
    Abstract: A fishing lure comprising a body (1) which is adapted to provide means (11) for producing action and which is flexibly connected (9, 10) to a framework member (2) such that the body can exhibit action without the framework member having to move. The framework member has provision (5) for connection of the fishing line, includes a weight (6), and also may carry components such as hook(s) (12, 13), and fish and strike attractors which may have weight and/or water resistance that would dampen action if carried by the body. Hook(s) may be carried by the member, the body, or both. The flexible connection and the parts of the lure are adapted and arranged so that when the lure is drawn through the water, the body exhibits action without spinning and without the action being precluded by contact with the framework member or its attachments.

  • Patent number: 5095922
    Abstract: Tobacco cut filler has an extremely high filling capacity. Tobacco cut filler is contacted with tap water under extraction conditions, and resulting aqueous tobacco extract is separated from the water insoluble extracted tobacco material. The extracted tobacco material is contacted with humectant, provided at a desired moisture level, and subjected to volume expansion conditions. Volume expanded extracted tobacco materials are used as smokable materials in cigarette manufacture.

  • Patent number: 5025812
    Abstract: Denicotinized tobacco cut filler is provided by (i) extracting the cut filler with an aqueous denicotinized extract and thereby providing a mixture of aqueous extract and extracted cut filler, (ii) deliquoring the mixture of aqueous extract and extracted cut filler such that a certain level of tobacco extract remains in contact with the extracted cut filler, and (iii) drying the deliquored tobacco extract/extracted cut filler to provide a processed cut filler. Greater than 90 percent of the nicotine present in tobacco cut filler can be removed therefrom using such process steps.

  • Patent number: 4767577
    Abstract: A process and apparatus for producing plastic-bound propellant powders and explosives in crystalline form, with the apparatus including an extruder comprising a casing with a feed opening, optionally a solvent supply opening and one or two extruder shafts with kneading and conveying segments. For processing the plastic binders, which polymerize photochemically or under X-rays, a casing section transparent for the rays is provided, with polymerization within the extruder being initiated by UV/VIS or X-radiation sources arranged around it and the radiation intensity and/or the wavelength of the radiation are controlled as a function of the pressure difference over a given path in a compression zone of the extruder, in such a manner that the propellant or explosive strand or strands leave the extruder in a dimensionally stable and cuttable manner.

  • Patent number: 3977099
    Abstract: The digging machine according to the present invention includes pairs of spherical blades which are rotated beneath a plant for forming a root ball and removing the plant. By operation of a pair of parallelogram linkages, the spherical blades are rotated beneath the surface of the ground, and spherical blade covers are moved downwardly to encompass the upper part of a root ball for convenient removal thereof.
