Abstract: ABSTRACT      The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease.  The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment.  The device achieves the desired properties by varying the hardness of the elastomeric material in its nucleus and annulus.  The present invention relates to a biocompatible intervertebral spacer comprising: a central core of a soft biocompatible elastomeric material shaped and sized so as to approximate the shape and size of a nucleus pulposus of a natural intervertebral disc; an outer ring of stiffer elastomeric material surrounding said central core to approximate the size and shape of a natural annulus fibrosus; and endplates comprised of a stiff biocompatible material and affixed, one to each end, to the outer ring central core.

Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE      Scanning samples of digital signals received in analog form are sent at intervals determined by the scanning clock pulses to a digital signal receiving network after analog-digital conversion for conversion of digital signals received in analog form.  The respective digital signal receiving unit delivers control signals derived from the received digital signals.  After filtering, these control signals are sent at predetermined intervals to a clock generator to deliver the scanning clock pulses.  Filtering of the control signals takes place in the form Ta(i) = al(Te(i) - a2(Te(i-1)) + Ta(i-1), where al and a2 denote a set of filter coefficients, Ta(i) and Ta(i-1) are filtered control signals at the times i and (i-1) and Te(i) and Te(i-1) are control signals delivered at times i and (i-1).  The set of filter coefficients is fixed in accordance with the value of the instantaneous control signal deviation.  The filtered control signals are then sent to the clock generator in quantized form.

Abstract: 1,119,772. Cooling liquids in bulk. BOLIDEN, A.B. 3 Dec., 1965 [7 Dec., 1964], No. 51404/65. Heading F4S. A liquid, particularly a highly corrosive liquid such as hot sulphuric acid, is cooled in an upright (cylindrical or oval) chamber by a fluid coolant such as sea water which circulates through groups of tubes 9 (either U-tubes or Field tubes being preferred) each group comprising a radial series of tubes interconnected through header compartments in a structure forming the top cover for the chamber, and the total tube crosssectional area of a group increasing progressively outwardly from the centre of the chamber. The cover structure comprises a lid 5 in which are formed sector-shaped openings. These are closed by header sections (See Fig. 2) from which the tubes extend into the chamber. Each section has its own inlet and outlet 11, 12 leading to main header 17, 18. The liquid to be cooled enters the chamber through an inlet 2. An impeller acting against the inlet stream, causes continuous recirculation of liquid within the chamber to somewhat reduce the temperature of the liquid before it contacts the tube surfaces. Contact by the corrosive liquid with the joints between the tube ends and the headers is prevented by the provision of a cylindrical baffle 6 extending downwardly from the lid 5. The baffle causes a gas pocket to be formed above the liquidas the level rises. Wave shaped inserts may be inserted into the tubes to create turbulence in the coolant. These inserts are preferably of a material more readily ionizable than that of the tubes whereby any tendency to galvanic corrosion, will erode only the inserts. The coolant is maintained at a higher pressure than that of the container liquid to prevent the entry of corrosive liquid into the tubes in the event of leakage. The tubes and headers are of stainless steel and may be lined with copper.

Abstract: A roll for use in a calender has a stationary carrier for a hollow cylindrical shell whose end portions are supported by combined radial and axial bearings surrounding annular bearing members which, in turn, surround the end portions of the carrier. The carrier defines with each bearing member a set of chambers which are sealed from the atmosphere and can receive pressurized hydraulic fluid to ensure that the end portions of the shell are biased toward a second roll with a requisite force as well that the end portions of the shell are stabilized against lateral and/or other stray movements. The fluid in the chambers ensures that the shell can be acted upon by large forces without unduly stressing the antifriction bearings. The bearing members flank a hydrostatic bearing unit which acts between the central portion of the shell and the carrier.

Abstract: A special picture such as, for example, a dot structure similar to a fine checkerboard pattern or a line structure is generated on the monitor to be calibrated. The monitor picture is recorded by means of a semiconductor camera. The picture segment, and thus the resolution, must be selected in such a manner that the fine dot structure is detected with full resolution in the camera signal. The camera signal is evaluated by means of a known image processing system. The sharpness of the picture recorded by the camera is determined by the histogram calculation. The width of the histogram curve is a measure of the sharpness of the picture.

Abstract: A field portable X-ray fluorescent spectrometer is described including a multichannel analyzer (2) and a plurality of interchangeable sensor heads (4). Each sensor head includes a shutter (100) which, when open, permits one of several radiation sources (80, 82) to irradiate a material to be analyzed. The returned radiation is detected by a corresponding detector (86, 90), which provides corresponding data in response. This shutter has calibration plaques attached to it so that, when closed, the plaques are exposed to the radiation sources and return radiation having selected energy distributions to the detectors. The multichannel analyzer uses the resulting detector data to calibrate the sensor head. Each sensor head includes circuitry (290) for identifying itself to the mutichannel analyzer. The analyzer automatically adapts its operation in accordance with this identification. When the shutter is open, the multichannel analyzer utilizes the detector data to accumulate an energy spectrum of the material being analyzed, and displays the spectrum on a display screen (12). A cursor control (28) allows the operator to move a cursor along the displayed spectrum. A display (32) is automatically provided with a display of the symbol of the element, if any, having its major spectral peak at the position identified by the cursor. Secondary indications identify other positions along the spectrum at which peaks would appear if the element were present. Memory (202) is provided for storing a number of reference spectra, any of one of which may be displayed on the screen along with the acquired spectrum for comparison purposes. The memory (202) also stores previously acquired spectra for later analysis. The analyzer also includes other operational features, such as normalization, window control, and ratio and concentration determination, to permit the operator to quantitatively analyze material in the field.

With a second compound comprising a cation capable of donating a proton and a bulky, labile anion containing a single boron atom, and a plurality of aromatic radicals capable of stabilizing the zirconium cation formally having a coordination number of 3 and a valence of +4 which is formed as a result of the combination, said second compound having the general formula:         [L'-H]<sup>+</sup>[BAr<sub>1</sub>Ar<sub>2</sub>X<sub>3</sub>X<sub>4</sub>]<sup>-</sup>Wherein:L' is a neutral Lewis base;H is a hydrogen atom;[L'-H]<sup>+</sup> is a Bronsted acid;B is boron in a valence state of 3;Ar<sub>1</sub> and Ar<sub>2</sub> are the same or different aromatic or substituted-aromatic hydrocarbon radicals which may be linked to each other through a stable bridging group; andX<sub>3</sub> and X<sub>4</sub> are, independently, selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals, organometalloid radicals and the like. Many of the catalysts thus formed are stable and isolable and may be recovered and stored. The catalysts may be preformed and then used to polymerize olefins, diolefins and/or acetylenically unsaturated compounds either alone or in combination with each other or with other monomers or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined in a suitable solvent or diluent at a temperature within the range from about -100°C to about 300°C. The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal. The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.
