Abstract: A spinal fusion system method and apparatus can include: providing segments including a first segment and a second segment; and coupling the first segment to the second segment with a flexible member, the flexible member configured to have a deformable state based upon a temperature of the flexible member being below a transition temperature range or based upon a stress being applied to the flexible member, and the flexible member configured to enter a shape-set state from the deformable state based on the temperature of the flexible member rising above the transition temperature range, or based upon the stress being removed from the flexible member and the temperature of the flexible member being above the transition temperature range.

Abstract: Apparatus and method used to reduce the movement between vertebrae or fractured bones. The implantable device can be deformed from its shape-set configuration for ease of deployment and return to a pre-set shape upon completion of deployment. The apparatus can serve to stabilize fractured bones or as a distraction device and support structure between vertebrae. Device may be made of a material with shape memory and superelastic properties which facilitate the method of implantation. The pre-set shape of the device may include dimensions/geometries which are similar to the natural curvature of the human spine or bone without the use of hinging or connection between multiple pieces. Once deployed, the device can serve to constrain the flow of bone growth material between the inside and outside of the device.

Abstract: A rolling apparatus has a frame and a first eccentric journal sleeve mounted on the frame, defining a first axis, and having axially inner and outer ends. A first shaft journaled in the sleeve has respective inner and outer ends at the first-sleeve inner and outer ends. The first-shaft outer end projects axially from the frame and carries a workpiece-deforming first roller. A rocker is displaceable transversely of the axis on the frame and carries a second eccentric journal sleeve defining a second axis generally parallel to the first axis and having axially inner and outer ends. A second shaft journaled in the second sleeve has respective inner and outer ends at the second-sleeve inner and outer ends. The second-shaft outer end also projects axially from the frame and carries a workpiece deforming second roller forming with the first roller a workpiece-receiving nip.

Abstract: A device for forming loops from a wire strand emerging from a wire rolling train using a rotating looper, wherein the device includes a conveyor onto which the loops are placed while the conveyor is moving, wherein a driving unit, a looper and a roller conveyor, a chain conveyor or the like, are arranged following the wire rolling train and wherein the driving unit and possibly also the looper are arranged inclined relative to the horizontal. The driving unit and the looper are arranged at a fixed predetermined angle of inclination relative to the horizontal, while the conveyor on which the loops are placed is constructed so that its angle is adjustable relative to the horizontal.

Abstract: A pair of roll support shafts which are supported by bearings provided at both ends of the roll support shafts, wherein, between the bearings, toothed drums are mounted on the roll support shafts or the circumference of the roll support shafts is provided with toothings. Outside of the bearings, roll disks can be mounted on the ends of the roll support shafts, wherein one of the toothed drums meshes with a drive pinion mounted on a parallel drive shaft and the other toothed drum meshes with a loosely mounted intermediate pinion, wherein the drive and the intermediate pinion also mesh with each other. The roll support shafts are each supported in a free end of a single-armed tumbler lever which is swingable about the longitudinal axis of the drive pinion or the intermediate pinion, wherein the tumbler levers are supported relative to the roll stand by means of adjustable and securable rigid or elastic support members and the free ends are supported relative to each other through elastic members.

Abstract: Wires are coiled by rotating about a main axis a curved laying tube having an upstream end opening generally at the axis and directed axially upstream and a downstream end opening radially offset from the axis and directed generally tangentially and feeding a leading end of the wire into the tube upstream end so that the wire issues from the downstream end of the tube in a curved condition and is laid in a succession of turns on a surface below the downstream end. Passage of a trailing end of the wire through the laying tube is detected and a drum having an inner surface directed toward and centered on the axis at the tube downstream end is closed around the downstream end of the tube to confine the wire inside the drum as passage of the trailing end through the laying tube is detected. The drum is opened from around the downstream end of the tube after passage of the trailing end through the tube and the drum is held open until detection of passage of another trailing end through the tube.

Abstract: A cassette-type roll stand for a two-high roll pair, wherein the bearing chocks of the roll stand are guided in a cassette formed by two housing frames which can be moved into and out of the roll stand. The housing frames are constructed as upwardly open U-shaped frames having oppositely located side members, wherein the side members are provided with guides for the bearing chocks of the lower roll and wherein one of the side members has extension projections with pivot bearings for the sides of the bearings chocks of the upper roll facing the pivot bearings. The other sides of the bearing chocks facing away from the extension projections are connected through spring-elastic connecting rods to the corresponding sides of the bearing chocks of the lower roll. In addition, an adjusting device and support and measuring devices for the cassette-type roll stand are arranged in the support frame.

Abstract: In an arrangement for heat treatment of steel wire, the wire, after emerging from a continuous wire rolling mill, is placed by a laying head onto a horizontal conveyor and is transported on the horizontal conveyor in the form of a row of successive and overlapping loops. The wire is subjected to surface treatment during the transport and is collected at the end of the conveyor by a loop collecting unit to form a wire coil and is transferred to a coil conveying unit. Behind the laying head, a second loop collecting unit which can be moved into and out of the conveying path of the horizontal conveyor is provided. The second loop collecting unit includes a coil conveyor with transfer units which can be operated as selected for transferring the wire coils to coil heating units or to coil cooling units.

Abstract: A rolling mill for wire or bar steel with a continuous light section steel or wire train, comprising a single or multi-line breakdown train with pilot stands, at least one single intermediate train comprising a cooling distance with subsequent soaking distance and a group of intermediate stands located downstream of said breakdown train as well as a finishing train downstream of said intermediate train with a single line group of finishing stands is disclosed, for overcoming unequal temperature distributions across the bar length and cross-section to compensate for varying finishing velocities because of cross-sectional differences caused by unavoidable longitudinal pull between the stands of the breakdown train. Specifically, a first soaking or compensation distance 10 with 180.degree. loop of the rolled stock guided through the horizontal loop former is located between the pilot stand and the group of intermediate stands and a second compensation or soaking distance with 180.degree.

Abstract: A combined, continuously operating high-speed light-section and wire mill composed predominantly of so-called cantilever stands or CL stands with overhung-mounted collars. In the roughing train and in the intermediate train and/or in the finishing train, some rolling mill stands with a modular unti with double-mounted collars are arranged. A CL modular unit of the CL stands with overhung-mounted collars can be exchanged as required against a modular unit with double-mounted collars. The second bearing of the modular unit is arranged in a box stirrup which can be coupled to the gear box of the CL stand. The collar can be assembled and disassembled with an automatically actuated, preferably hydraulically acting quick fixing device which includes piston-cylinder units for clamping and releasing the collar on the shaft in axial and in radial direction. The modular unit is a roll box of sandwich construction with box plates which can be separated from each other.
