20090236025 | APPARATUS AND METHODS FOR PRODUCING FOAMED MATERIALS - Apparatus and methods for producing a foamed material. Pressurized gas is introduced into a multiple-component mixture that contains a catalyst-containing component and a crosslinker-containing component. The multiple-component mixture may be directly mixed and combined with the gas in a mixing device. Alternatively, the multiple-component mixture may be combined in a first mixing device and this mixture may be subsequently combined with the gas in a second mixing device. When dispensed onto an application target, the gas entrained in the multiple-component mixture expands to form the foamed material. | 09-24-2009 |

20140030493 | TWO-PACK PLASTISOL INK COMPOSITIONS FOR SCREEN PRINTING OF TEXTILES - Plastisol ink compositions are disclosed containing (meth)acrylate polymer, non-phthalate ester plasticizers, and optionally, pigment, filler, thixotropic agent, and other additives. The plasticizers are separated into lower and higher solvating plasticizers, and the composition for handling and storage is separated into two masterbatches with the (meth)acrylate polymer mixed with the lower solvating plasticizer. The plastisol can be used an ink of various colors for use in application to textiles. The plastisol ink compositions avoid polyvinyl chloride polymer resins and phthalate plasticizers conventionally employed in plastisol inks. | 01-30-2014 |

20090254181 | Intervertebral spacers with side wall accessible interior cavity - Intervertebral spacers and methods of promoting fusion bone growth in the space between adjacent vertebrae are provided. The spacers include an elongated body having a first end, a second end and an outer surface. Side walls connect the first and second ends. The elongated body also defines an interior cavity. The side wall defines an opening to the interior cavity in a side of the elongated body. At least one of the first and second ends has a discontinuity, such as a concave surface, for nesting with an adjacent spacer. The methods of promoting fusion bone growth include utilizing the inventive spacers described herein. | 10-08-2009 |
20110178551 | RETAINING SYSTEM - A retaining system for affixing a component to a vertebral body is disclosed. The system comprises a component and a retaining mechanism. The component comprises an inner surface configured to engage at least a portion of an endplate surface of the vertebral body, and an outer surface configured to engage the retaining mechanism, wherein the outer surface of the component comprises a first face directed substantially toward the vertebral body. The retaining mechanism comprises an inner surface configured to engage the outer surface of the component, and an outer surface configured to receive a fastener, wherein the inner surface of the retaining mechanism comprising a second face directed substantially away from the vertebral body. | 07-21-2011 |
20110184521 | PROSTHESIS CONNECTION MECHANISM - A prosthesis comprising a component for engaging a surface of a vertebral body is disclosed. The component comprises a bone-engaging surface and an outer surface that is not bone-engaging, wherein the bone-engaging surface is configured to engage a portion of the surface of the vertebral body, wherein the vertebral body has been configured to engage with the bone-engaging surface, and wherein after the component is engaged with the vertebral body, at least at a location of an area of a junction between a vertical surface and an endplate surface of the vertebral body, the outer surface of the component has a shape that is substantially similar to an anatomical shape of the vertebral body. | 07-28-2011 |
20110196373 | BONE PREPARATION DEVICE - A bone preparation device for shaping endplates forming an intervertebral disc space between two adjacent vertebrae includes a cutter component and a cutter-positioner component. The cutter-positioner is arranged to limit the distal travel of the cutter component and to restrict the range of motion of the distal end of the cutter component. The bone preparation device also includes a rotational interface between the cutter component and the cutter-positioner component. The rotational interface is structurally arranged to permit the cutting blade to be rotated at the same time the cutter component is restricted in its range of motion. | 08-11-2011 |

20090222093 | Nucleus Implant and Method of Installing Same - A nucleus implant is disclosed. The nucleus implant can be configured to be installed within an intervertebral disc between an inferior vertebra and a superior vertebra. Further, the nucleus implant can include a solid core and an expandable chamber that can be disposed at least partially around the solid core. The expandable chamber can be expanded from a deflated position to an inflated position. | 09-03-2009 |
20090222097 | Nucleus implant and method of installing same - A nucleus implant is disclosed. The nucleus implant can be configured to be installed within an intervertebral disc between an inferior vertebra and a superior vertebra. The nucleus implant can include an expandable core and an expandable chamber that can be disposed at least partially around the expandable core. The expandable chamber can be expanded from a deflated position to an inflated position. Further, a hardness of the expandable core when inflated can greater than or equal to a hardness of the expandable chamber when inflated. | 09-03-2009 |

20090090658 | METHODS FOR ENHANCING EFFICIENCY OF BITUMEN EXTRACTION FROM OIL SANDS USING LIPIDS AND LIPID BY-PRODUCTS AS PROCESS ADDITIVES - In a method for enhancing the efficiency of separation of bitumen from oil sands ore, lipids, lipid by-products, and lipid derivatives are used as process additives for ore-water slurry-based bitumen extraction processes or in situ bitumen recovery processes. The lipids, lipid by-products, and lipid derivatives act as surfactants reducing surface and interfacial tensions, thus promoting breakdown the oil sands ore structure and resultant liberation of bitumen from the ore. Lipid treatment does not deleteriously affect release water chemistry in bitumen recovery processes, and it does not appreciably affect the fuel value of recovered bitumen. Lipids which may be effectively used as additives include biodiesel, tall oil fatty acids, monoglycerides, vegetable oil, and soap water, and combinations thereof. Lipids may also be used as process additives to enhance the efficiency of clean-up of hydrocarbon-contaminated soils, in the production of bitumen-water or oil-water emulsions, and to enhance the transportability of emulsions such as in pipelines. | 04-09-2009 |
