  • Patent number: 9079575
    Abstract: A machine having a powertrain including an engine operably connected to a torque converter and a transmission. The machine includes a control system receive an activation signal indicative of an automatic mode operation of the machine and command the torque converter to remain in a direct-drive mode while the transmission shifts from a first gear ratio to a second gear ratio. The control system also limits engine speed below a first engine speed limit when a gear ratio setting of the transmission is indicative of the second gear ratio.

  • Patent number: 8584411
    Abstract: An apparatus for increasing the insulation value of a window system with a weep hole includes a flapper valve with a buoyant flap articulating relative to a non-moving portion. The flap is positioned on the window frame over the weep hole proximate the inside of the structure in which the window system is installed and the non-moving portion is attached to the window frame. The flap may be held against the frame around the weep hole by gravity and/or by the elastic memory of a portion of the flap, such as a plastic hinge. The flapper valve is closed when dry to diminish the flow of ex-filtration through the weep hole, but opens in response to being flooded with water due to the buoyancy of the flap, opening the weep hole and allowing the water to drain.

  • Patent number: 7231304
    Abstract: Methods, systems, and articles of manufacture consistent with the present invention identify a flaw in a structure by comparing a first interference pattern resulting from a first wave signal and a second wave signal propagating through the structure to a second interference pattern resulting from the first wave signal and the second wave signal propagating through the structure. The second interference pattern is obtained after obtaining the first interference pattern. It is determined whether there is a flaw in the structure by determining whether the first interference pattern deviates from the second interference pattern by a predetermined variance.

  • Patent number: 5835692
    Abstract: A video imaging system and method that allow a user to manipulate an image displayed on a video display are disclosed. The video display includes a mechanism that controls a portion of a virtual display area to be shown on the display. The video imaging system and method of the present invention include a virtual display that is mappable to an actual video display. A mapping notation is provided to allow for a virtual three-dimensional orientation or mapping notation icon, which allows the user to control which portion of the virtual image area is displayed with respect to the entire virtual image area. The mapping notation icon is manipulated, by a device, such as a mouse or trackball, to allow the user to manipulate the virtual image area to display another portion of the virtual image area.

  • Patent number: 5565602
    Abstract: A process which can be used for producing thiolcarbamates is provided wherein the process comprises contacting a reaction mixture with a hydrocarbyl chloride such as, for example, benzyl chloride under a condition which is sufficient to produce a product mixture wherein the reaction mixture comprises carbonyl sulfide, an amine such as, for example, a secondary amine, a solvent; the solvent comprises a tertiary amine; and the reaction mixture, hydrocarbyl halide, and solvent are each present in an amount sufficient to effect the production of a thiolcarbamate. Optionally, the reaction mixture can also comprise a metal hydroxide. Further optionally, the product mixture can be contacted with a metal hydroxide if the reaction mixture does not comprise a metal hydroxide.

  • Patent number: 5226733
    Abstract: The voltage across a temperature responsive diode supplied with constant current is sensed and applied to two analog amplifiers with different gains. The output from each amplifier is applied to a sample and hold circuit. The output from each sample and hold circuit is applied to an analog to digital converter to produce two binary signals. The minimum binary value of one signal corresponds to the minimum voltage drop; the maximum to the drop at an intermediate temperature. The minimum binary value of a second signal corresponds to the drop at the intermediate temperature and the maximum binary value of this signal corresponds to the drop at a maximum temperature. Both binary signals are applied to the multiplexer which selects one signal to address a stored temperature in a look-up table.

  • Patent number: 4461479
    Abstract: A golf club is provided with a grip end having increased weight in order to improve the accuracy and control of the swinging of the golf club. The golf club has a head, a shaft having an outer end, and a balance point at a location intermediate the ends of the golf club. A weighted member is mounted to the golf club between the location of the balance point and the outer end of the golf club. The weighted member is in intimate contact with the inner surface of the hollow club shaft and has an enlarged head portion abutting the outer end of the shaft. The weighted member is encased in a flexible sleeve for absorbing thermal and mechanical stresses during use of the club. The weighted member moves the balance point of the golf club from the original location of the balance point to a new point that is between the original location and the outer end of the club.
