A prosthetic spinal implant having a securing member for fixing the implant relative to an adjacent bone. In one form, the securing member is deployable into a portion of the vertebral space for affixing the implant between the vertebrae. The securing member may be disposed substantially within the body of a bearing member of the implant when the securing member is in an undeployed orientation. In other forms, the securing member is provided separately from the implant such that it may be inserted into the intervertebral space after the implant has been placed in an implanted orientation between the vertebrae. In such forms, the securing member is configured for ease of insertion between an outer bearing surface of the implant and an adjacent bone via linear or rotary motion.

A method of monitoring belt orientation and / or belt travel of a belt conveyor apparatus includes measurement of compression and / or thrust stress patterns within the belt as it passes over a support roller arrangement by measuring means embedded in the belt. The measured signal is recorded and associated with a specific support roller. The signal pattern allows conclusions to be drawn about misalignments of the belt or possible defects in the support rollers. A belt conveyor apparatus has measuring means embedded in the belt and including at least one multi-axis sensor for detecting the stress variations in the belt.

A product has a coding pattern on its surface. The coding pattern may include symbols representing at least two different values and where each symbol comprises a raster point and at least one marking. The raster point is included in a raster that extends over the surface and the value of each symbol is indicated by the placement of the marking in relation to the raster point. The markings may each have a spatial extent that, in combination, may at least partially form the image.

A method of detecting and identifying bacteria, micro-organisms or plants in a liquid or gaseous medium, the bacteria, micro-organisms or plants being of the kind which produce signaling molecules in intercellular space, includes positioning a biosensor in the liquid or gaseous medium, the biosensor having a biolayer matched to specific signaling molecules to be detected whereby the biolayer is reactive thereto in a manner which varies operation of the sensor. Such variation of the operation of the biosensor is detected to thereby determine the presence and purpose of the bacteria, micro-organisms or plants in the liquid or gaseous medium.

A multi-station machine vise that is disclosed herein that utilizes soft jaws, which are symmetrical and machineable on all four sides. The jaws being identical in size and configuration makes them interchangeable / usable on any vise station, which results in reduced operating costs. The movable jaws are precisely located and fastened to the vise utilizing a jaw carrier, which incorporates a pull-down action to eliminate jaw lift. The jaw carrier includes a downwardly positioned wedge design that engages a corresponding wedge on a slide that moves the jaw carrier and the jaw. Incorporating the pull-down mechanism into the jaw carrier disposed between and slide and the jaw allows for simplifying the design and manufacture of the jaws.

A prosthetic spinal implant having a deployable securing mechanism that is deployable into a portion of the vertebral space for affixing the implant between the vertebrae, the securing mechanism having tactile feedback means comprising a surface for transmitting tactile feedback during deployment of the securing mechanism. A spinal implant having deployable securing means that interface with the implant to prevent the deployable securing means from retracting after deployment. An implant that utilizes its resilient properties to provide the user with tactile feedback with which the user may ascertain the position of the securing mechanism. A system and tools for sizing and implanting implants with the aforementioned characteristics.

Systems and tools for inserting and securing an implant within the intervertebral space. An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. The implant may be provided with various securing members for fixing the implant within the intervertebral space. A tool may be used to insert the implant, which includes a plurality of shiftable implant engaging members that are shiftable between non-engaging and engaging configurations to alternatively release or hold the implant.

The production of a diutan polysaccharide exhibiting increased viscosity properties as compared with previously produced polysaccharide of the same type of repeating units. Such an improved diutan polysaccharide is produced through the generation of a derivative of Sphingomonas sp. ATCC 53159 that harbors a multicopy broad-host-range plasmid into which genes for biosynthesis of diutan polysaccharide have been cloned. The plasmid provides the capability within the host Sphingomonas strain to produce multiple copies of genes for such polysaccharide synthesis. In such a manner, a method of not just increased production of the target diutan polysaccharide, but also production of a diutan polysaccharide of improved physical properties (of the aforementioned higher viscosity) thereof is provided. Such a diutan polysaccharide has proven particularly useful as a possible viscosifier in oilfield applications and within cement materials. The inventive methods of production of such an improved diutan polysaccharide, as well as the novel cloned genes required to produce the improved diutan within such a method, are also encompassed within this invention. Additionally, the novel engineered Sphingomonas strain including the needed DNA sequence is encompassed within this invention.

The invention relates to a preparation method of metal-chelated magnetic beads connecting tricarboxymethyl ethylenediamine. The preparation method comprises the steps: adding an alkali liquid to hydroxyl magnetic beads, and activating to obtain a mixture I containing the activated hydroxyl magnetic beads and the alkali liquid; adding dimethyl sulfoxide, epoxy chloropropane and sodium hydroxide with the concentration of 1 mol / L to the obtained mixture I, stirring for 12-14 hours at the temperature of 60 DEG C, and thus obtaining epoxy activated magnetic beads; adding a sodium bicarbonate solution and ethanediamine to the obtained epoxy activated magnetic beads, and carrying out slow oscillation for 20 hours at the temperature of 50 DEG C, to obtain processed epoxy activated magnetic beads; and adding a sodium hydroxide solution and a sodium bicarbonate solution to the obtained processed epoxy activated magnetic beads, mixing evenly, then adding bromoacetic acid, and stirring at room temperature, to prepare the metal-chelated magnetic beads connecting tricarboxymethyl ethylenediamine. The method is simple, and the prepared metal-chelated magnetic beads have strong metal binding ability and large combination capacity, and can be used for removing metal ions in solutions and biological macromolecules.
