  • Patent number: 5661853
    Abstract: Hand wear such as a glove having a plurality of relatively hard sockets affixed to the outside of the glove at the outer end of each digit receiving receptacle. The sockets are sized to receive the distal phalange of a gloved digit and provide an increased resistance to deformation, thereby protecting the finger tips during tasks which are finger tip intensive.

  • Patent number: 5660420
    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.

  • Patent number: 5648015
    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.

  • Patent number: 5645774
    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.

  • Patent number: 5629998
    Abstract: Apparatus for forming a refractive index grating in a waveguide in accordance with the invention includes a waveguide formed from a material that changes its index of refraction when exposed to a beam of optical radiation, a source of coherent optical radiation for forming a beam of radiation, a mirror arranged to intercept a first part of a beam and to reflect the first part of the beam through an angle, and a phase delay plate arranged to intercept a second part of the beam for delaying the second part of the beam propagating through the plate, in which the mirror and the phase delay plate are arranged so that the first part of the beam and the second delayed part of the beam form an interference pattern on the waveguide for changing the index of refraction of the waveguide, in a pattern corresponding to the interference pattern for forming an index grating in the waveguide.

  • Patent number: 5628851
    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.

  • Patent number: 5620456
    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.

  • Patent number: 5615514
    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.

  • Patent number: 5615921
    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.

  • Patent number: 5605383
    Abstract: A radial brush having a plurality of discrete brush segments mechanically affixed to or mechanically affixed to and bonded to a central core. Each brush segment is a preformed discrete component having a predetermined degree of splay. The brush segments are affixed to the core for rotation about an axis of rotation, so that splay of the individual fibers lies in a plane orthogonal to the axis of rotation and splay in the axial direction may be precluded.

  • Patent number: 5603161
    Abstract: A visual wear indicator which may incorporate a shaving aid, such that the visual wear indicator corresponds to released shaving agents, wear or oxidation of a cutting edge. The visual wear indicator may include a shaving aid composite which exhibits a first color to the user during an initial use and a different color during a subsequent use, wherein the transition from the first color to the second color is designed to correspond to a predetermined parameter of the shaver. The visual wear indicator may also include a metallic surface having an oxidation rate which parallels the oxidation rate of a cutting edge and provides a sufficient surface area to exhibit a second color upon detrimental oxidation of the blade.
