  • Golf practice mat
    Patent number: 6156396
    Abstract: A golf practice mat includes a relatively thick base pad formed of a resilient elastomeric material, e.g. foam rubber, and an artificial grass carpet slidably positioned on the base pad. An elastic biasing mechanism is provided for positioning the carpet on the pad. When a golf ball on the carpet surface is forcibly struck, the carpet can slide a limited distance to absorb the club force, so as to lessen the reaction force onto the golfer's hands and arms. The elastic biasing mechanism then returns the carpet to its original position.

  • Picture frame clamp
    Patent number: 6138999
    Abstract: Two picture frame members can have their beveled end surfaces glued together by using a clamp mechanism to force the frame members into pressure contact at the end surfaces. The clamp mechanism includes a stationary stop member having a convex V-shaped edge surface contacting inner edges of the frame members, and a movable clamp member having a concave V-shaped edge surface contacting the outer edges of the frame members. Prongs on the stationary stop member prevent undesired shifting of the frame members while the clamp member is being advanced to exert pressure forces on the frame members.

  • Advanced motor driven impeller pump for moving metal in a bath of molten metal
    Patent number: 6082965
    Abstract: An apparatus for moving a stream of molten metal in a bath of molten metal having a housing and steel alloy legs to prevent the housing from rising in the molten metal. The steel legs are protected by tubular shields made of a heat resistant material. The shields each has a lower end attached to the housing and has an inner diameter that is larger than the leg's outer diameter to accommodate the thermoexpansion of the leg. Inert gas is introduced in the space between the steel leg and the shield to form an oxygen-free environment around the leg.
