  • Patent number: 6244667
    Abstract: An improved bicycle wheel is disclosed in which spokes (22) and spoke bores (18) are paired at the flanges of the hub (12) and the circumferential distance between adjacent pairs is grater than the distance between the spokes and the bores in a given pair, providing improved torque transmission and reduced spoke stresses at spoke crossover points. Such a wheel may be constructed to have reduced dish by comparison with a conventionally laced wheel. In this case, the wheel is one which, when laced conventionally, would be dished such as a rear wheel with at least one sprocket or a front wheel with a brake disk. In a rear wheel embodiment, the spokes extend from inside to outside, through a proximate hub flange and along the outside to inside through the opposed hub flange. In a front wheel embodiment, the spokes extend from inside to outside through the proximate hub flange along an inside or disk surface thereof.

  • Patent number: 6238140
    Abstract: A method for burying pipe or tile and, especially, double walled drainage tile. The method comprises the steps of digging a relatively wide trench having a bottom with a desired grade and loosening the soil in a central portion of the trench bottom by pulling a groove cutter which is attached to an excavating bucket along the trench bottom so that the bucket rides on the trench bottom and the groove cutter extends below the bottom surface of the trench. After the groove cutter loosens the soil, a modified trench shield or trench box is advanced along the trench bottom. The trench shield is provided, at its leading end, with a groove shaper which removes loosened soil from the central portion of the trench and forms a relatively narrow groove in the bottom of the trench. The width of the groove, adjacent the floor of the trench, may be a little larger or smaller or equal to the drain tile diameter.

  • Patent number: 6145938
    Abstract: Improvements in torque transmitting wheels are disclosed. The improvements afford more balanced torque transmission as between the proximal spokes, adjacent to a torque transmitting member, such as a sprocket, sprocket cluster or disc for a brake, and the distal spokes which are opposite from the torque transmitting member. A wheel according to the present invention is provided with radially oriented proximal spokes and tangentially oriented distal spokes. This shifts the majority of the torque transmission task to the distal spokes which, in a torque transmitting wheel, are under less tension than proximal spokes under static conditions. A torque transmitting member is mounted on the hub, adjacent the proximal hub flange, and the distance from the proximal hub flange to a plane through the proximal edge of the rim is substantially less than the corresponding distance from the distal hub flange.

  • Patent number: 6143441
    Abstract: A multi-layer sheet useful as a separator (10) in a lead acid battery is disclosed. The sheet comprises at least a first layer (12) and a second layer (14) and having been produced by the method consisting of the steps of forming the first layer (12) by depositing a first, substantially binder free furnish consisting essentially of glass fibers onto the wire (36) of a paper making machine (30) and forming the second layer (14) by depositing a second, substantially binder free furnish consisting essentially of glass fibers and silica powder or another suitable silicate powder onto the first layer (12) on the wire (36) of the paper making machine (30). The silica or silicate powder has a particle size and being present in the second layer (14) in an amount such that, if the second substantially binder free furnish was deposited directly on the wire (36) of the paper making machine (30) a significant portion of the silica or silicate powder would pass through the wire (36).

  • Patent number: 6068889
    Abstract: A method for lubricating glass contacting surfaces of glass forming equipment is disclosed. The method comprises the steps of delivering MAPD gas to a venturi at a low pressure, preferably below 10 p.s.i., and delivering oxygen to the venturi at a lower pressure, usually half or less than half of the pressure at which the MAPD gas is delivered to the venturi. The MAPD gas and the oxygen are mixed in the venturi and delivered to and through a nozzle which is directed toward a glass contacting surface. The mixture is ignited as it leaves the nozzle; its flow is controlled so that the temperature of the flame is between approximately 1500 and 1800 degrees K. By controlling the temperature of the flame, the method is operable to deposit on the glass contacting surface a lubricating coating of graphite including a substantial percentage of flat plate graphite.

  • Patent number: 5979478
    Abstract: Apparatus for delivering a water treatment chemical to a water intake in a water system is disclosed. The water system has a water inlet and a pump for withdrawing water from a natural body of water, such as an underground aquifer, a river, a lake or the like. In a water system that draws water from a body of water that is inhabited by zebra mussels, the apparatus is operable, when water is being drawn into the system, to deliver a zebra mussel control agent to the inlet of the system to eliminate zebra mussels, if present, from the water system and to prevent the infestation of the water system by zebra mussels. In a water system that draws water from an underground aquifer, the apparatus is operable, when the system is drawing water, to deliver a water treatment chemical to or near the water inlet for the system and to cause thorough mixing of the water treatment chemical with the water, before it reaches a reservoir in the system, whereby undesired impurities are controlled or removed from the water.

  • Patent number: 5951299
    Abstract: The present invention involves the use of numerical digits with markers and attribute tags as a means to represent quantities, facilitate mathematical manipulation, and solve problems. The given number of markers on each digit corresponds to the value of the digit. For example, the digit three is enhanced with three markers. The attribute tags are also provided with a given number of markers, for example, ten, for math problems in base ten. The digits and the attribute tags are then used to represent and solve math problems including, but not limited to, learning ones, tens, hundreds, thousands columns, addition, multiplication, subtraction, and division, of whole numbers, of fractions, of negative whole numbers and of negative fractions, as well as decimals and exponents. The problems are quantitatively viewed, manipulated, and solved directly on the numerical digits incorporating the markers and attribute tags.

  • Patent number: 5947042
    Abstract: A combination of a bar having a bore therein, and a tufting tool module for the bar including a bore extending therethrough. A fastening screw extending through the bore of the module, and threaded into a cooperatively threaded portion of the bore of the bar. The module has a plate shaped body having a first plane face which bears against a first plane face of the bar, and is urged into contact with that face by the fastening screw. There is a first stop strip extending from the first face and along a first edge of the module body. The first face of the module body is locked in a given angular position relative to the fastening screw. In one embodiment a first collar which projects from the first face of the module body, is positioned annularly around the bore and received in the bar with a locating fit. The first stop strip is closely adjacent the surface of the bar.
