摘要:
The longitudinal implant is fastened to bones on either side of a damaged area through a connecting device. Said implant is comprised of a filament or fiber composite material and said connecting device is made of a material harder than said longitudinal implant. The longitudinal implant is preferably made of a carbon filament composite material, wherein the filament are encapsulated in a polymer matrix.

The invention relates to a steel and a processing method for high-strength fracture-splittable machine components that are composed of at least two fracture-splittable parts. The steel and method are characterized in that the chemical composition of the steel (expressed in percent by weight) is as follows: 0.40%≦C≦0.60%; 0.20%≦Si≦1.00%; 0.50%≦Mn≦1.50%; 0%≦Cr≦1.00%; 0%≦Ni≦0.50%; 0%≦Mo≦0.20%; 0%≦Nb≦0.050%; 0%≦V≦0.30%; 0%≦Al≦0.05%; 0.005%≦N≦0.020%, the rest being composed of iron and smelting-related impurities and residual matter.
摘要:
A rotary vane pump is disclosed which comprises a cylindrical housing, and a cylindrical rotor eccentrically mounted for rotation within the housing. The rotor includes a slot mounting a pair of oppositely oriented hook-shaped vanes, so as to define a hook space adjacent each end of the overlying vanes. A fluid, such as lubricating oil, is delivered to each hook space during that portion of its rotation shortly before its bottom dead center position, and the delivered fluid is pressurized during that portion of its rotation shortly after its bottom dead center position to assist in moving each vane outwardly from its bottom dead center position.

Spectral, densitometric, or color measured values are detected on sheet printing materials during the printing process in a sheet-fed printing press. The measured values are determined on sheets as they are moving through the printing press and the measured values are used in real-time by a computer to control parameters for controlling the printing process in the sheet-fed printing press.
摘要:
The pair of lumbar interbody implants is designed to be pushed laterally in a space between adjacent vertebrae for replacing the disc between these vertebrae. Each implant comprises a first and a second saggital wall and an anterior wall at one end and a posterior wall at the other end. The two implants are asymmetric to each other and are therefore more appropriate for the transforaminal lumbar interbody fusion. Preferably a first implant has a first saggital wall with an outer surface that is curved and a second saggital wall that is essentially plane.
摘要:
An instrument of an instrument set is used to insert an implant into a disc space. The implant comprises a first cage and a second cage and the instrument comprises a distal end configured to push the cage first inserted into the disc space laterally in its proper anatomical location. Said distal end of the instrument has a tip, which is curved and has a curved inner side configured to contact an outer curved side of the first cage. The instrument set allows the insertion of two cages through a relatively small incision in the interdisc space in a simple jet safe procedure.
摘要:
A printing press for processing sheet printing materials includes at least one printing unit, a computer and a measuring device for monitoring printing quality during a printing process. The measuring device has a sensing device for measuring by color or spectrally to register the printing material. At least one sheet-guiding element leads the sheet printing material past the sensing device. A measuring device for monitoring printing quality during a printing process in a printing press for processing sheet printing materials, is also provided.
摘要:
The medical implant is constructed of a fiber reinforced plastic. That fibers (50a, 50b) are generally aligned in layers (C, D, E), wherein the fibers of at least two different layers having different orientations. The fibers are long and oriented in relationship to the biomechanical requirements. The implant can oppose multi-directional forces and can be manufactured with the appropriate strength and stiffness.
摘要:
A device and method for spatially resolved photodetection and demodulation of temporally modulated electromagnetic waves makes it possible to measure phase, amplitude and offset of a temporally modulated, spatially coded radiation field. A micro-optical element (41) spatially averages a portion (30) of the scene and equally distributes the averaged intensity on two photo sites (51.1.51.2) close to each other. Adjacent to each of these photo sites (51.1) are two storage areas (54.1, 54.2) into which charge from the photo site can be moved quickly (with a speed of several MHz to several tens or even hundreds of MHz) and accumulated essentially free of noise. This is possible by employing the charge-coupled device (CCD) principle. The device combines a high optical fill factor, insensitivity to offset errors, high sensitivity even with little light, simultaneous data acquisition, small pixel size, and maximum efficiency in use of available signal photons for sinusoidal as well as pulsed radiation signals. The device and method may be used in a time-of-flight (TOF) range imaging system without moving parts, offering 2D or 3D range data.
