Abstract: A sliding plate of a sliding closure unit is moved to selected throttling positions thereof to relatively restrict the size of a discharge passage through the sliding closure unit. The control of movement of the sliding plate is achieved in a level control operation by a processor. Periodically this level control operation is interrupted and the sliding plate is moved in a throttling position change operation from one throttling position through a completely open position of the discharge passage to another throttling position, such two throttling positions employing throttling surfaces of the sliding closure unit on opposite sides of the discharge passage. The throttling position change operation includes regulating at least the throttling position at which the sliding plate is located at the conclusion of the throttling position change operation by a sequence control program included in the processor that controls the level control operation.

Abstract: A novel method of making a ceramic core for use in casting a metal component includes freezing a ceramic slurry comprising a ceramic powder filler, a freezable liquid and a gelling agent in a mold to form a frozen core shaped body. The frozen core shaped body is removed from the mold and thawed to room temperature. A high viscosity gel is provided in the core shaped body at room temperature that is strong enough to retain the core shape until the body can be fired to form a porous, sintered ceramic core. The gel present at room temperature may be formed as the ceramic slurry is cooled in the mold cavity to form the frozen article shaped body and/or as the frozen core shaped body is thawed to room temperature.

Abstract: A method for the sequential casting of steel strip in steel strip casting equipment wherein under normal operating conditions a steel melt is fed through a pouring tube having discharge ports into the pouring area of a cooled ingot mold at a location below the surface of the melt in the mold and is thereafter removed from the mold in the form of steel strip by the combined operation of mold oscillation means and strip discharge means. After the feed of melt is interrupted, anchoring rods are partially longitudinally immersed into the melt laterally of the pouring area of the mold, and the surface of the melt in the mold is lowered to a level below the pouring area. After a desired interval, the melt feed is continued, and the level of the surface of the melt in the mold is allowed to rise above the discharge ports of the pouring tube. Thereafter, casting flux is applied to the surface of the melt, and the operation of the mold oscillation means and the strip discharge means is resumed.

The apparatus includes a wheel with serrations on its periphery, and means for rotating the wheel in a vertical plane. Means are provided for controlling the relative positions of the wheel and the upper surface of the body of molten metal which is subjected to change. In this manner, the serrations on the bottom of the wheel are disposed a preselected distance into the body of molten metal. When the serrations rotate out of the body, molten metal collects on the serrations and freezes into solid flakes. Means are provided for removing the flakes from the serrations and for collecting the flakes at one location on the periphery of the wheel.

Abstract: The grip is comprised of a deformable cover formed of a thermoplastic material which is stable and semi-rigid at normal ambient temperatures and is soft and deformable when heated in boiling water. The cover is attached to an implement handle heated and deformed to the shape required by a specific implement user. The method of forming the grip includes the steps of coating the implement handle with a cover material, heating the implement handle until the material has become softened, and grasping an implement handle while the cover is soft and deformable, thereby causing the cover to be molded to a user's specific shape. The high coefficient of friction and the moldability of the material results in a superior grip.

The pivot corner comprises a unitary pivot pin to allow tilting of the window and optionally a restraining guide to assure proper orientation of the window. The unitary construction of the pivot corner reduces the number of parts needed for tilting or removable single-hung and double-hung window units to a minimum and simplifies construction of these window units.

Abstract: An improved adjustable wheel structure mainly adapted for use in a trailing vehicle on which a yacht, boat or motorcycle can be mounted for transportation; the present wheel structure is provided with a special nut member having its inner surface half threaded and half smoothed, and the nut member is able to be adjusted forward or backward so that the threaded inner surface thereof can be selectively engaged with a vertically disposed adjusting screw rod which has a smaller diameter than the central through hole of the slidable nut member so that the wheel structure can be smoothly adjusted in height; as the threaded side of the nut member is adjusted to disengage from the screw rod with the smoothed side thereof in contact with the adjusting screw rod, the wheel structure can be adjusted quickly rather than in stepwise manner.

Abstract: A casting method and apparatus making use of a twin belt caster which has an upper belt, a lower belt and dam members disposed between both opposing longitudinal edges of the upper and lower belts. The upper belt, lower belt and dam members in cooperation provide a continuous casting mold which is inclined at a predetermined angle from the horizontal plane and into which a melt of steel is poured. The lower belt provides a smaller cooling effect than the upper belt so that the solidification of the melt is retarded in the region near the lower belt as compared with the region near the upper belt.

The stay is guided by a roller (7) free to turn on a pin (8) fastened to the frame (2). This stay has a notch (9) which is entered by the roller (7) in order to hold the lid open, and a notch (10) holding the lid closed. Means of adjusting the tension of the spring (6) make it possible to fix a safety position (.alpha.) before the complete closure of the lid.

Abstract: A bracket hinge and bracket members (10, 10') with a spring biased and movable locking member (30). The locking or latch member (30) has ear parts (38, 39) received in locking openings (25, 25') where wedging surfaces (40, 41) on the ear parts cooperate with complimentary surfaces (42, 42') on the bracket members for bringing the bracket members into a tight end-to-end alignment when the bracket members are in an extended position. When the locking member (30) is moved to an unlocking position, pivoting of the hinge about a pivot pin (32) automatically places locking pins (70, 71) in a circular shaped groove (55) on the locking member (30) to retain the locking member (30) in an unlocked position. In pivoting the hinge from an extended position to a folded position, longitudinal spring members (80, 81) are placed under tension over annular rollers (60, 61) so that the spring tension in a folded position assists in return of the hinge from a folded position to an extended position.

Abstract: A hinge for mounting an access door on a room air conditioner has a hinge member having a tang at one end engaging a slot on the air conditioner front frame to mount the hinge member in a fixed position. The other end of the hinge member has a pair of resilient legs interspaced by a projection and which carry projecting trunnions on their outer ends. The door has a notch in its side having opposed side walls with bores that receive the projecting trunnions to pivot the door about the hinge member. The hinge provides a self-latching arrangement by a projecting, resilient tongue on the hinge member which engages a projecting lug on the door to resiliently bias the door to a closed position when it is within a predetermined distance from the closed position.

Abstract: A spring system for stabilizing bifolding door hinged positions includes an integral "C"-shaped spring with at each end of the "C"-shape a respective straight shank formed at right angles to the plane of the "C"-shape in parallel spacing from each other. On each shank is a rotatable tubular sleeve bearing with a collar-shaped enlargement at the end adjacent the "C"-shape, and a retainer on the free end of each shank that keeps the tubular sleeve bearings in place. Installation is by insertion of the tubular sleeve bearings in parallel-spaced drilled holes in the top edges of two doors that are hinged together so that the spring assembly substantially bridges the hinges and biases the faces of the doors together to keep them in the open position, and biases the edges of the doors together to keep them in the closed position.
