Abstract: A spinal interbody implant includes an outer shell, a fill material disposed within the outer shell and a plurality of tubes extending from a first outer surface of the implant to a second outer surface of the implant through the fill material. The fill material is more porous than the outer shell and the plurality of tubes.

Abstract: A dental implant for implantation into an oral environment of a patient includes a body having a coronal end, an apical end, an inner surface adjacent to coronal end, and an outer surface extending from the coronal end to the apical end. A first area of the dental implant is a first color and a second area of the dental implant is a second area. A method of making a dental implant includes providing a dental implant having a body with a coronal end, an apical end, an inner surface adjacent the coronal end, and an outer surface extending from the coronal end to the apical end; coloring a first area of the dental implant a first color; and coloring a second area of the dental implant a second color.

Abstract: An optimization system for generating a visual representation of business goals in a contact center is disclosed. The optimization system includes a monitor module configured to monitor current status of the business goals of the contact center. The optimization system further includes a computing module configured to compute values of the business goals and generate the visual representation. The optimization system further includes a drag module configured to enable a user to change value of a business goal from an actual operating value to a desired operating value. The optimization system further includes a display module configured to display modification in values of associated business goals due to the change in the value of the business goal.

Abstract: An orthodontic adhesive includes a curable resin monomer component; a quaternary curing initiator system; and filler. Another orthodontic adhesive having a W/C ratio (working time to curing time ratio) of at least 10, 12, 14 or 20, includes a curable resin monomer component; a curing initiator system; and filler. The adhesives are suitable as light-curing and may include a colorant. Suitable colorants include reversible, thermochromic dyes. The adhesive may also include a resin toughening component.

Abstract: Packages for dispensing dental appliances of the type used in corrective orthodontic treatments, methods of using such packages, and methods of manufacturing such packages. The package generally includes a holder and drawers containing the dental appliances that are removable from the package. The characteristics of the dental appliances positioned in each individual drawer are appropriate for application to different quadrants of the patient's teeth. The drawers of the package may be color coded with regions on a setup card so that the dental appliances, while remaining positioned in the drawers, may be organized among the regions according to the intended quadrants for bracket application. Other color coding schemes are possible involving the drawers, the brackets held by the drawers, the setup card, and the brackets themselves.

Abstract: The invention relates to apparatus for cutting a series of spaced-apart continuous linear slits in a sheet of flexible plastics material, for example in the manufacture of an ajustable width blind. In one embodiment the apparatus includes a feed roller for feeding sheeting to be slit to a support means, a plurality of slitting blades movable in a direction transverse to the direction of travel of the sheeting and means for controlling the blades so that they cut to a depth less than the thickness of the material. In a second embodiment the blades are stationary and are adapted to cut in the direction of travel of the material. The blades may be mounted on leaf springs biased towards the material to be cut, means being provided for controlling the biasing force. Alternatively, a stop may be provided to control the depth of cut of the blades.

Abstract: The invention relates to apparatus and a method for cutting a series of spaced-apart continuous linear slits in a sheet of flexible plastics material, for example in the manufacture of an adjustable width window blind.

Abstract: The invention relates to a slip coupling for preventing the overwinding of the motor spring of a roller blind. In one embodiment the slip coupling is incorporated as part of a bracket for supporting one end of the roller. The bracket has a cylindrical bearing which is rotatable within a circular aperture in the face of the bracket and receives a pin of the spindle of the roller so as to be rotatable therewith. The bearing carries a spring the ends of which engage with stops on the face of the bracket so that the bearing is prevented from rotation when the torque exerted by the motor spring is below a predetermined level. When the motor spring is overwound the ends of the springs are caused to flex to override the stops and so reduce the tension in the motor spring. In a second embodiment the slip coupling is located within the roller.
