Abstract: A method of producing methacrylic acid using a hydrotalcite catalyst and subcritical water is described.

Abstract: A mobile device and system which simulates human motion. The device includes a base with a drive system for providing motion to the device. A receiver is provided which controls the drive system the receiver receives wireless control signals. Pads and a self-stabilizing component are provided on the device. The device accurately mimics the unpredictable motion of a human motion to provide a safer alternative to live interaction to increase participant safety and decrease the incidence of injuries during practice or drill sessions. The system includes at least one mobile device. The mobile device includes: a base having a drive system for providing motion to the device; a receiver which controls the drive system the receiver receives wireless control signals; and self-stabilizing component provided on the device. The system also includes a transmitter for transmitting the control signals to the receiver.

Abstract: A mobile device which simulates player motion, the device includes a ball drive, omni-directional members, at least one motor, a controller and pads. The ball drive provides rolling motion to the device. The omni-directional members are positioned proximate to and in engagement with the ball drive. The at least one motor is connected to the omni-directional members, the at least one motor providing the motive force to drive the omni-directional members and the ball drive. The controller controls the motor. The pads are positioned on the device. The device accurately mimics the unpredictable motion of a live player to provide a safe alternative to live play to increase player safety and decrease the incidence of injuries during practice sessions.

Abstract: A carrier is provided for holding a lens mold that includes a first mold half defining a first optical surface and a second mold half defining a second optical surface. A first frame defines a front surface. A holder assembly is in operative communication with the first frame and is configured to receive the first mold half. The holder assembly is adjustable to rotationally secure the first mold half so that the first optical surface faces outward from the first frame front surface and in any of a plurality of rotational positions with respect to an axis normal to the first frame front surface. A second frame is configured to receive the second mold half so that the second optical surface faces outward from a front surface of the second frame. The second frame front surface opposes the first frame front surface upon alignment of the first frame and the second frame in an operative position.

Abstract: Improved equipment and method for spinning filaments for nonwovens using an integral spinbank including one or more spinplates producing filament bundles separated by one or more central conduits for quench air. Embodiments include high velocity quench air driven into the central conduit or quench air blown or drawn in from outside the filaments into the central conduit. Means may also be provided for removal of undesired waxes and/or other condensates through a central exhaust removal using the central conduit. As quench air velocity is increased through the central conduit, the streams tend to improve total quench flow by deflecting opposing flows into a uniform stream. Other variations include division of quench air into flow zones that may be independently controlled and varying the angle of quench air flow and/or the spinplates to maintain separation distance between quench air and filament bundles.
