Abstract: A bolt construction for use in an espagnolette locking system for the multi-point locking of sashes is made up of a linking rod (16) and a locking pin (17), one or the other of which is of fixed length and the other of which may be any one of a plurality of different lengths, the rod and pin being adapted to be connected together with a snap fit in any one of a plurality of different positions, thereby allowing the length of the interconnecting rod and pin to be chosen to fit a particular size of sash. The construction also provides a bolt construction for use in an espagnolette locking system for multi-point locking of sashes, which bolt construction is formed for assembly within a rebate in a face of the sash by means of a snap fit within the rebate. The construction also extends to a sash fitted with two such bolt constructions.

Abstract: A process for preparing a ferrite in which a green body containing at least about 50 weight percent of iron compound is first sintered and then cooled. During the cooling cycle, from about 1,000 to about 700 degrees centigrade, the body is contacted with a reduced oxygen atmosphere containing less than 10 volume percent of oxygen. From 700 to 200 degrees centigrade, the reduced oxygen atmosphere contains less than 1 part per thousand of oxygen. Thereafter, the sintered body is treated to remove at least some sharp edges and to change its permeability; and it is then contacted with an etchant.

Provisions are made for adding variable customized information on at least a portion of each data tag. Such data-tags are readily assembled by hand and are useful as warning signs in an industrial environment.

Abstract: A method and apparatus for establishing the magnetic permeability of a batch ferrites at a predetermined target permeability. Ferrite parts are sintered to achieve a magnetic permeability greater than the target permeability. The sintered parts are then tumbled to suppress the magnetic permeability below the target permeability. The parts are then exposed to a chemical wash to increase the magnetic permeability and continuously monitored to allow setting the magnetic permeability at the target permeability.

Abstract: This invention relates to modifying an existing tub to form a bathtub assembly having a recessed opening in the tub apron to allow easy access to a high walled tub apron for users who are unable to step over the apron of the tub. The initial step in the method is the formation of a plug on the intact tub apron. The plug is removed and is transformed into a custom mold for the tub cap. The tub cap is formed within the mold by applying cap building material to the interior surface of the mold. The cap is allowed to cure and is then removed from the mold. A section of the tub apron is then cut out to form a rough opening upon which the tub cap is securely mounted to allow an access passage into the bathtub.

Abstract: An obturator assembly for penetrating body tissue, includes a handle assembly having a finger-actuated trigger member, a sleeve member connected to and extending from the handle assembly, an obturator shaft at least partially positioned within the sleeve member and engageable with the finger-actuated trigger member of the handle assembly and a cutting mechanism supported by the distal end portion of the obturator shaft. The cutting mechanism is deployable for cutting action upon movement of the trigger member. A method of using the obturator assembly is also disclosed.

Abstract: The present invention features a shopping bag handle that is ergonomically designed for easily carrying heavily-ladened shopping bags. The handle is substantially straight with a slight convex arc along its underside. The convex arc along the mid-section of the handle provides an ergonomic effect that conforms to the grip of a hand. An eye-loop is located on each distal end of the carrying handle. The loops of the shopping bag are easily threaded onto the eye-loops because of the downwardly-facing geometry of the latter. The central axis of the handle passes substantially through the contact points between the respective eye-loops of the handle and the loops of the shopping bag, thus reducing the moment of inertia between the middle portion of the handle and its distal ends. This reduced moment of inertia provides for a more stable carrying handle, substantially eliminating the tendency of a shopping bag to sway or rock about the handle.

Abstract: An animal trap comprising an elongated, U-shaped cage with a cover and vertically slideable doors at each end is disclosed. The trap further includes a triggering mechanism that results in the activation of at least one trap door when an animal removes bait from a bait tray. The triggering mechanism includes a vertical bait pin positioned above a hole in the bait tray, a flexible linking means connecting the bait pin to a latch pin that holds the trap door in an open position. When the bait is removed from between the bait tray and the lower end of the bait pin, the bait pin falls and accelerates through the hole in the bait tray creating tension in the flexible member which actuates the latch pin allowing the trap door to fall and lock in a closed position.
