    摘要: A folding table (1) with a table top (5) and a pair of breakaway legs (15) supporting the top. A brace member (47) at each end of the table has a leg assembly (7,9) attached thereto. A top supporting beam (11) extends along the table top between the brace members. The support beam is pivotally mounted to the table top. Each leg assembly has a hinge structure (35) near its top end and a foot structure (24) at its bottom end. The hinge (35) allows the leg (15) to break down and fold inwardly against the table top. A pair of leg braces (81,83) are attached to the support beam and are moveable with the beam. Each leg brace is removably attached to a corresponding leg by a locking assembly (87). When the leg braces (81,83) are attached to the leg, they transfer downward force from the table top to the legs at a point below the hinges (35) to keep the legs in the unfolded position. The locking assembly (87) can be disengaged and the leg braces pivoted out of the way to allow the legs to be folded. A wire gallery (13) is removably attached to the leg braces (81,83) below the table top.

    摘要: A fluid mixing device (1) includes a chamber (3) and a bluff body (4) defining one end of the chamber (3). A first fluid inlet (5) is located toward an opposite end of the chamber (3) from the bluff body (4) and arranged to direct fluid toward the bluff body (4). A region substantially surrounding the bluff body (4) has a flow divider (8) defining second fluid inlet(s) (11) to the chamber (3) and mixed fluid outlets (12) from the chamber (3). A fluid flow from the first fluid inlet (5) and/or from the second fluid inlet (11) establishes a recirculating vortex system (14) within the chamber and results in a mixture of fluids from the first fluid inlet (5) and the second fluid inlet(s) (11) being directed through the mixed fluid outlets (12).

    摘要: A novel hand-held pressure molding device about the size of a pair of pliers is used to produce a contoured matrix of dental restorative composite resin for use in restoring teeth to their approximate original shape. The matrix produced by the device is bonded in place to establish the old contour of the tooth and then the space between the tooth and the matrix is filled with uncured dental restorative composite. After curing by actinic light, the matrix bonds to the rest of the filling and the tooth, forming the outside contour of the restored tooth. The present device avoids the need for supplying preformed and pre-shaped dental matrices in multiple shapes and sizes to the dental practitioner, allowing the practitioner to manufacture his matrices in his office from the identical material subsequently used to fill a tooth.
