Abstract: An infant exerciser includes a base plate, a turntable rotatably coupled to the base plate, and a mounting plate removably coupled to the turntable. A chair support assembly is coupled to the mounting plate. The chair support assembly receives a chair to couple the chair to the mounting plate. A foot actuating assembly is coupled to the mounting plate and is positioned adjacent the chair support assembly. The foot actuating assembly has a platform member for being actuated by feet of the infant when the infant is seated in the chair. A drive assembly is coupled to the mounting plate such that the foot actuating assembly is positioned between the chair support assembly and the drive assembly. The drive assembly is actuatable by the platform member and engages the base plate such that actuation of the drive assembly rotates the turntable with respect to the base plate.

Abstract: Junctions in multilateral well structures are sealed by employing a variety of degrees of premachined components and a variety of sealing embodiments, including casing segments having premachined windows, side pocket members which are adapted to reside within the string during run in and move laterally to the deployed position, woven members, cement filled ECPs, etc. Also disclosed is a downhole milling device which cuts a window in a casing segment or other material based upon a predetermined geometric pattern imposed upon the cutting tool by an integral template.

Abstract: A ladle having a hydrocarbon-free, expendable refractory insulating lining that is chemically compatible with the molten metal to be placed in the ladle.

Abstract: A tundish consisting essentially of a rigid metallic outer casing having walls and a bottom at least one permanent layer of heat insulating material adjacent said casing, and a unitary, integrally formed expendable inner lining made of a hydrocarbon-free refractory composition and having at least one liquid metal flow control device integrally formed therewith, the lining being chemically compatible with the molten metal to be placed in the tundish. The invention also comprises the unitary integrally formed expendable lining and the method to form the same.

Abstract: A lance adapted for metallurgical treatment comprising an elongated tube-shaped member having a refractory coating thereon and a sleeve of carbon bonded refractory fitted about the tube-shaped member at the slagline to protect the slagline region thereof.

Abstract: A ski pole having a grip pivotally mounted on a pole member to enable the grip to move from an in-line position to a transverse position on the pole member. A latch normally holds the grip against pivotal movement. A trip on the grip unlatches the grip for pivotal movement. The trip is so located on the grip that it can be actuated by the thumb of the hand grasping the grip. The pressure on the trip may be relieved after the latch is tripped. A cam arrangement enables the latch to automatically re-engage when the grip is returned to its in-line position.
