摘要： This invention pertains to a rotary disk tool which utilizes pressurized water as the working fluid. When an operator engages a trigger on a novel control handle and valve assembly, pressurized seawater enters the rotary disk tool through the control handle and valve assembly into a seawater powered vane motor. The shaft of the seawater powered vane motor, is coupled to a drive gear. The drive gear, in turn, is in operative engagement with a driven pinion coupled to an output shaft which drives an abrasive disk. Seawater exhausted from the motor into a gear and pinion housing provides lubrication for the drive gear, driven pinion, and the bearings used with the gear and pinion. The seawater is then exhausted from the housing as a fan spray directed onto the back of the abrasive disk so as to reduce drag of the disk in water and to flush away loose material from the work surface.

摘要： A connector mate/demate tool provides remote coupling and decoupling of connector sections with a rotating locking ring on one section of the connector and where the other section is rigidly attached to some fixture. The tool mates the connector sections by first searching for a key-slot engagement of parts while exerting a small longitudinal force and then rotating the locking ring until the two sections are secured. Demating is accomplished by rotating the locking ring in the reverse direction and pulling the two connector sections apart.

摘要： A controlled gas generator system is provided which has a reaction chamber,he reaction chamber having top and bottom ends. A bed of reactant material is disposed within the chamber intermediate its top and bottom ends. Liquids are located within the chamber, one of the liquids being nonreactive with the reactant. The liquids are dissimilar in specific gravity so that the liquids interface substantially along a cross-sectional plane of the chamber. With this arrangement, gas will be produced when the interfacial plane is vertically disposed on one side of the bed of reactant material, and gas will not be produced when the interfacial plane is vertically disposed on an opposite side of the bed of reactant material. Provision is made for selectively adjusting the vertical position of the interfacial plane above or below the bed of reactant material so that gas can be selectively generated.

摘要： An improved device and a method for stabilizing lumbar vertebrae in a human spine for the purpose of fixing the vertebra with respect to other vertebra and with respect to other parts of the spinal column. This device comprises a plate, bone screws, bone screw clamp portion, spacers, and rigidizing stop locks. The bone screw clamps may be clamped firmly to the plate for a fully rigid system. Alternatively the screw clamp portions may be held apart, with clearance between them and the plate, which will allow for axial motion of the screw with respect to the plate for implant load sharing and dynamized motion.

摘要： A device and a method for stabilizing vertebrae in a human spine for the purpose of fixing one vertebra with respect to other vertebrae and with respect to other parts of the spinal column. This device comprises bone screws that clamp to a plate to maintain the plate in contact with the vertebrae. The device may be fabricated from non-metals, metal, alloys, or composite materials. A tapered screw head is pulled into the plate with the taper extending through the plate into the underlying bone. Extending the taper into the bone moves the screw thread stress raiser into an area of lesser deflection. This strengthens the fixation by increasing the rigidity and reducing the risk of screw breakage. Extending the taper into the underlying bone has also been shown to strengthen the taper lock.

摘要： This invention relates to a method and materials in combination for bonding screws to a fixation plate or to a skeletal bone using chemical means. The chemicals include solvents, glues, or bonding agents, which act to improve the strength of bone screw to plate or the bone screw to skeletal bone interface. Interface refers to the contact area between the bone screw and either the plate or skeletal bone. The fixation device usually comprises a plate with bone screws implanted within the human skeleton. The bone screw maintains the plate in contact with the bone or maintains another structure such as a tendon in contact with the bony skeleton. The chemical bonding is in addition to or in place of a mechanical means to bond the bone screw to the fixation plate or to the skeletal bone. It provides for added strength to the bone screw interface with a plate or skeletal bone, reducing the probability of screw loosening and or migration.

摘要： A method and a device are provided for stabilizing vertebrae in a human spine for the purpose of fixing one vertebra with respect to other vertebrae and with respect to other parts of the spinal column. This device comprises a plate and bone screws fabricated from metals. The bone screw maintains the plate in contact with the vertebrae. A tapered screw head is pulled into a machined tapered hole, locking the screw to the plate. The taper is configured to be self-locking preventing the screw from backing out. The taper may be within the fixed structure of the plate, or within an insert placed into the plate.
