  • Patent number: 12239899
    Abstract: Snowboards are constructed by initial manufacture of a base sub-assembly including fewer than all layers of the snowboard, e.g., a base layer, edges, and a stabilizing layer. These layers are permanently bonded together into a unitary base sub-assembly. The running (bottom) surface is then finished to provide a desired surface consistency by eliminating undesired irregularities from the manufacturing process, e.g., using a conventional base grinding machine. Subsequently, the base sub-assembly and remaining snowboard layers (e.g., top sheet and a core sandwiched between reinforcing layers) are permanently bonded together into a unitary final snowboard assembly, which may then be worked to form a finished snowboard. Snowboards may be either flat or non-flat in both the longitudinal and transverse directions.

  • Patent number: 12220785
    Abstract: Multiple holding surfaces of a chuck table are disposed in such a manner that the heights thereof from a reference surface are in increasing order along a first direction parallel to each of them. Thus, in a case of using this chuck table, creep-feed grinding for workpieces each held by a respective one of the multiple holding surfaces can be executed in states in which a grinding unit is positioned at different heights. In this case, the workpiece for which the creep-feed grinding has been executed is located on the lower side as viewed from the grinding unit when another workpiece is ground. Due to this, in this creep-feed grinding, a specific workpiece can be prevented from being ground twice.

  • Patent number: 12208489
    Abstract: One array of grindstones is used for in-feed grinding and creep-feed grinding. Therefore, it is not necessary to position a chuck table that is holding a plate-shaped workpiece with respect to two different arrays of grindstones. As a result, a period of time required to grind the plate-shaped workpiece can be shortened. Furthermore, lower surfaces of the grindstones are used for the in-feed grinding, whereas side surfaces of the grindstones are used for the creep-feed grinding. Consequently, the amount by which the grindstones are worn can be smaller than that in a case where the plate-shaped workpiece is ground to a predetermined thickness in only the in-feed grinding or the creep-feed grinding.

    Abstract: This invention relates to tire tread wear monitoring. A sacrificial magnet portion is arranged in a tread of the tire so that it undergoes wear along with the tread and generates a useful magnetic field signal indicative of remaining tread thickness. With a magnetic field sensor arranged on or in the tire, an overall magnetic field signal is measured, which includes the useful magnetic field signal, and a superimposed interfering magnetic field signal generated by magnetizable material contained in the tire. A non-sacrificial magnet portion is used to saturate the magnetizable material at least locally so as to make the interfering magnetic field signal sensed by the magnetic field sensor substantially independent of the useful magnetic field signal sensed by the magnetic field sensor. Further aspects of the invention relate to tires, e.g., vehicle tires, featuring a tire tread wear monitoring system.

  • Patent number: 11440163
    Abstract: A compoundless buff and method of making a compoundless buff using a coating solution formulated with abrasive particles dispersed or suspended using a surfactant or suspension agent and which also contains a self-crosslinking acrylic binder emulsion that binds abrasive particles to nonwoven cloth of a buffing article when the coating solution is applied thereto forming a relatively hard abrasive-containing coating that enables the buffing article to abrasively treat a surface without having to separately apply any buffing or polishing compound. A preferred coating solution formulation further contains a lubricant emulsion that produces a lubricant and abrasive-containing coating of the buff having lubricant interspersed with binder and abrasive particles thereby reducing friction during buffing or polishing.

  • Patent number: 11407616
    Abstract: A belt of an elevator system includes one or more tension elements extending longitudinally along a length of the belt, and an elastomeric jacket at least partially enveloping the one or more tension elements. The jacket defines a traction side configured to be interactive with a traction sheave of the elevator system and a back side opposite the traction side. A protective tape is applied to the elastomeric jacket at the back side. A method of assembling an elevator system includes forming a belt, and installing the belt in a hoistway of the elevator system. One or more additional components of the elevator system are installed in the hoistway. A protective tape is removed from a jacket of the belt after installation of the one or more additional components is completed.
