  • Patent number: 7213361
    Abstract: The present invention is directed to a support stand for a fishing pole holder, and is particularly adapted for ice fishing. In use, the stand holds the fishing pole in a generally upward angled position. The fishing pole is held in a pivotal position, so that upon sensing a hit on the attached line, the fishing pole tips downward. Legs, for supporting the body of the stand, can be placed in a first position or a second position, depending on the conditions of use for the stand. When not in use, the legs of the stand can be stored within the body.

  • Publication number: 20070084178
    Abstract: A leaf pickup tool. A stationary rake head is fixedly mounted to a rod. A movable rake head is pivotally mounted to the stationary rake head with movement controlled by means of a handle slidably mounted to the rod and connected to the movable rake head by a rigid member. A spring associated with the handle allows for positioning of the movable rake head relative to the stationary rake head.

  • Patent number: 7002675
    Abstract: To locate/size contaminants at the surface of a dielectric or semiconductor material, a P-polarized beam of light from a monochromatic solid-state source is disposed specifically at Brewster's angle and focused to form an illuminated quasi-elliptical spot on the surface that produces effectively no reflected or scattered light from the surface. The spot is scanned over the entire surface so as to assure multiple passes of any contaminant through the spot. On each pass through the spot a contaminant will produce scattered light. A novel high numerical aperture reflective or refractive system is disposed above the surface to always view the spot and to collect/redirect the bulk of the contaminant scattered light to a detector. Illumination at Brewster's angle combined with the high numerical aperture scattered light collector/redirector maximizes the signal-to-noise ratio from the detector. These core components are packaged with support subsystems as a uniquely compact and portable apparatus.

  • Publication number: 20010023870
    Abstract: A package is provided with a lid and container that are heat sealed together. A multi-ply sheet material is provided for being thermoformed to define the container which has a tapering wall and bulge-resistant bottom end. Prior to thermoforming the container from the sheet, the sheet is heated with oval pads on a plurality of plates which are arranged in a configuration to facilitate control of the sheet temperature. A plug is used in the thermoforming process to contact the sheet and position the sheet within a die. A lid sheet is heat sealed to the container sheet over the thermoformed containers so as to produce a pair of spaced-apart, annular bead heat seals. The package is completed by severing the sealed-together sheets at the periphery of the container with a punch and die set that produces and clean, smooth cut surface.

  • Patent number: 6096358
    Abstract: Aseptically sterilized package of a liquid nutritional product manufactured by (a) providing a multi-layered plastic sheet having at least one polymeric structural layer and at least one polymeric barrier layer; (b) passing the sheet through a peroxide bath; (c) locating the sheet in a sterile environment; (d) applying heat a plurality of times to the sheet; (e) forming the sterilized sheet into a container having a body portion; (f) filling the body portion with a liquid nutritional product; (g) sealing the container with a tabbed, multi-layered closure; and (h) separating the sealed container from the remainder of the sheet. Preferably the liquid nutritional product is infant formula. In the preferred embodiment of the invention, the sheet is a laminate having two structural layers, each being about 45% of the laminate thickness and secured to either side of the barrier layer, which is about 5% of the laminate thickness, by an adhesive layer of about 2.5% of the laminate thickness.
