Abstract: Disclosed is a robot apparatus with a capable and highly maneuverable drive system incorporating two differential swerve drive pods. The robot apparatus further includes a claw mechanism for grasping an object, a passthrough mechanism for moving the object horizontally and a lift mechanism for moving the object vertically. The robot apparatus allows for rapid manipulation and movement of objects such as cones.

Abstract: A circumferential matrix system having a matrix band and a body, such that the body comprises a handle, a housing and a base, and a spindle within the body is attached to the handle. The matrix band on one end is permanently affixed to the spindle and the matrix band on another end is permanently affixed to an inside wall of the housing. The circumferential matrix system can be tightened around a tooth without the need or use of a retaining ring.

Abstract: The present invention relates to restorative materials, in particular to glass-ionomer cements. More particularly, the present invention relates to glass-ionomer cements having particular utility in the repair of human hard tissue, in particular as dental restorative materials and in orthopaedic surgery. We describe a composition comprising a mixture of a glass ionomer cement and zinc phosphate. Preferably, the composition comprise from 40 to 95% by weight of glass ionomer cement and from to 60% by weight of zinc phosphate. The present invention also provides a powdered composition comprising a fluorosilicate glass and deactivated zinc oxide. Such that the zinc phosphate is formed in sith by reaction between the zinc oxide and phosphoric acid.

Abstract: A machining tool comprises a frame mounting an extendable yoke slidable with respect to the frame in a first direction through one or more mounting pillars. A tool motor is mounted on the yoke. A drive mechanism for the yoke is also mounted in the frame, with a drive motor to drive the yoke drive mechanism. A belt is between pulleys on the drive motor and mechanism to transmit drive between them. A rotatable sleeve is around the tool motor and on which sleeve the belt engages on opposite sides of the tool motor, whereby the tool motor can extend between the drive motor and mechanism, thereby resulting in a compact arrangement of the tool.
