  • Patent number: 5490350
    Abstract: A Christmas-tree stand (2) essentially consists of a housing (6) in which two clamping bars (18, 20) are rotatably supported so as to allow a swivelling movement around two support pins (22, 24). The activation of the clamping straps (18, 20) takes place via a central clamping device which essentially consists of a threaded rod (26) with two inversely threaded sections (32, 34) constructed thereon. When rotating the threaded rod (26), the free ends of the clamping bars (18, 20) are moved along by the nuts (30, 30') running along with the threaded sections (32, 34), so that a Christmas-tree trunk can be fixed or fastened between the clamping bars (18, 20).

  • Patent number: 5490372
    Abstract: A cotton stripper with an improved row unit having brush rolls and augers with parallel shafts driven by a gear drive. The parallel shafts permit the unit to be narrowed several inches compared with the conventional units. A cut-off member between the brush roll and auger has an edge which runs parallel to the shafts below the axis of the brush roll shaft to break up stalks and facilitate power feeding of stripped material toward the lower part of the auger. The auger housing is formed with angled flat walls for better stalk breakage. The row unit housing includes a light, low friction plastic cover with a quick attach and release mounting arrangement including a rear panel that serves both as a unit drive cover and a hold-down structure for the rear of the plastic cover. The cover includes inner and outer walls separated by a hollow interior for strength, rigidity and noise and weight reduction.

  • Patent number: 5490743
    Abstract: For providing an in-ground system for treating contaminated groundwater, of the funnel-and-gate type, a cylindrical caisson is driven into the ground. The native soil is augered out of the caisson, and porous treatment material substituted. The caisson is then withdrawn, leaving a prism of porous treatment material in the ground. A sheet metal barrier element is inserted into the ground, one portion of the element extending into the prism and the other portion into the surrounding soil. More prisms are provided as further treatment gates, and more barrier elements are arranged to funnel the groundwater through the gates.

  • Patent number: 5487619
    Abstract: A self-righting warning marker includes a base having a warning sign attached thereto and projecting upwardly therefrom. The warning sign is preferably formed of a polymer which is rigid yet resilient and flexible, to prevent breakage upon contact from a vehicle or the like. The base of the marker has a pivot surface extending between a rearward face and a bottom surface so that the marker will roll along the pivot surface from an upright orientation to a horizontal orientation if contacted by a vehicle. A ballast weight within the base is located such that the center of gravity of the marker is located forwardly of the pivot surface to thereby cause the marker to be self-righting. In a preferred embodiment of the invention, an illuminator is mounted on the marker, with a lens attached along an upper edge of the warning sign and a bundle of fiber optic cables extending through the panel of the warning sign to a power source in the base which includes a light and a battery.

  • Patent number: 5486067
    Abstract: A method and apparatus for marking a surface with a predetermined pattern is described. The apparatus includes a surface marking mechanism that supports a material dispenser. The material dispenser is manipulated along a number of axes including an x-axis, a y-axis, and a z-axis. In addition, the material dispenser is manipulated to rotate around a w-axis and to form a tilt angle with the w-axis. The surface marking mechanism includes movement devices for initial positioning of the mechanism and for re-positioning the mechanism to complete a selected pattern that does not fit within the border of the mechanism. The surface marking mechanism is responsive to control signals from a controller. The control signals are derived from a mathematical model characterizing the spatial relationship between the predetermined pattern, the material dispenser, and the surface to be marked.

  • Patent number: 5484228
    Abstract: The use of a cam member having a plurality of camming groups to cause a raising and lowering motion to be transferred to a cutting head to install a series of SNAP depressions in the surface of an asphalt road. Two cutting methods are disclosed, the first allowing cutting through the cut, the second allowing a near plunge cut to be made. Cutting through the cut permits a smaller diameter cutting drum than would fit the resulting cut while providing for a smooth action to the cutting procedure. A near plunge cut permits adaptation of existing equipment utilizing current use cutting drum which diameter approximate the shape of the resulting cut. Proper spacing is ensured by having the cam member in direct communication with the surface under treatment with movement provided by the installing machine. The optional adaptation of a skip pattern within the series is taught.
