  • Patent number: 10450227
    Abstract: A method is provided for producing a raised feature on a glass ceramic element, in which a glass or glass ceramic element is irradiated with electromagnetic radiation in a local region of the surface, the radiation passes through the element and is at least partially absorbed thereby so that the element heats up in the region of the irradiated electromagnetic radiation and is heated beyond a glass transition temperature. The irradiation is terminated after heating so that the heated region cools down to the temperature of material surrounding the local region. The heating causes a change in volume of the element, which brings about a local elevation in the surface that remains after the local region cools so that a surface deformation in the form of an elevation remains after cooling.

  • Patent number: 5366219
    Abstract: The hockey puck has a main body portion with opposite parallel surfaces. Ground engaging runners project from each of the opposite base portions of the puck and thus elevate the base surfaces of the puck from the ground to minimize surface contact between the puck and the ground. The ground engaging projections are equally spaced in a circular array at a rim portion of the puck. Openings in the puck concentrate weight at the center and periphery of the puck. The ground engaging projections and the main body portion are formed of different plastic materials, with each plastic selected for the most desirable physical properties and performance characteristics. Thus the ground engaging runners are relatively wear resistant with low ground friction whereas the main body portion is of relatively low hardness and provides the requisite stability and weight to the puck.

  • Patent number: 4995173
    Abstract: A shoe, boot, sneaker, etc. incorporates a foot-actuated pump which is connected to one or more expandable air bladders located in portions of the footware where contour fitting is desirable. Walking or running actuates the pump. An adjustable relief valve connected to the bladder releases air when a preselected pressure is exceeded. The relief valve is accessible externally for easy adjustment by the wearer. Regardless of the external ambient temperature or degree of user activity, the pump, in conjunction with the relief valve, maintains a preselected pressure and assures that the selected fit between the user's foot and footware is maintained at all times.
