Abstract: A body support apparatus, system, and method of reducing pressure on the pelvic structure of a non-ambulatory or semi-ambulatory individual. According to the invention, a body support apparatus provides pressure relief and a level base of pelvic support for wheelchair users. The body support apparatus provides enhanced pressure relief via layers of tissue density-specific pressure relieving layers of foam. In addition, the apparatus provides further pressure relief via gender specific pressure relief zones. The body support apparatus can be used in combination with a wheelchair to provide pressure relief and a pelvic postural support.

Abstract: Disclosed are surfacing materials formed from a suitable angular or sub-angular base sand mixture that is coated with a polymer or polymer/oil blend and then combined with short fibers to produce the final surfacing composition. The polymers and polymer/oil blends are selected to reduce temperature dependent viscosity variations in the surfacing materials, thereby providing a more consistent “going” for horses or other livestock being worked on these surfacing materials. Also disclosed are methods of manufacturing such surfacing compositions and methods of using such surfacing compositions in constructing riding venues including, for example, arenas and tracks.

Abstract: A mattress including a core foam layer having a first indentation force deflection at twenty five percent compression, a first density and a first thickness. The top outer foam layer has a second indentation force deflection at twenty five percent compression, a second density and a second thickness. The first intermediate foam layer is intermediate and coextensive with the core layer and the top outer layer, and has a third indentation force deflection at twenty five percent compression, a third density and a third intermediate thickness. The first indentation force deflection is greater than the third indentation force deflection and the third indentation force deflection is greater than the second indentation force deflection.

Abstract: A close proximity pavement grinder is utilized for grinding close to a raised structure such as a lower surface of curbs close to the curb wall. The grinding apparatus utilizes a wide grinding head with grinding blades mounted along the length of an arbor to grind the lower surface of the curb in a single pass. The grinder includes a narrow bearing and support at the outer end of the arbor and is driven at the inner end so that the grinding may be conducted within close proximity of the curb wall. The grinder has a pivoting grinding head that can be locked at various angles relative to the grinder to match the relative angles between the pavement and the lower surface of the curb.

Abstract: A pavement diamond grinder used for grinding and/or grooving pavement surfaces as the grinder carriage with a rotating arbor supporting radio blades. A cooling and dust control system delivers water to the arbor. The system includes a spray bar with nozzles that atomizes the water prior to engagement with the blades. The system utilizes a wiper debris removal device to clean the blades. In addition, a device that is utilized to effect turbulence adjacent to the blades and improve contact of the atomized water with the blades.

Abstract: A method of forming an impregnated fibrous sheet comprising impregnating a fibrous material with a tin catalyst to form a catalyst-impregnated material, treating the catalyst-impregnated material with a polyisocyanate composition to form a polyisocyanate-impregnated fibrous material, and curing the polyisocyanate-impregnated fibrous material to provide a resin-impregnated fibrous sheet. Laminated materials and a method of producing the same are also provided.

Abstract: A system for cutting slots in pavement has a first slot cutting vehicle with a cutting assembly having several pairs of rotating blades mounted to the first vehicle and vertically adjustable relative to the vehicle. A lift system moves the first vehicle between a first position wherein the lift is not engaging the ground and a raised position wherein the lift engages the ground and supports the vehicle. A slider assembly uses a hydraulic ram to move the vehicle horizontally on rails relative to the lift when the vehicle is at the raised position. In operation, the vehicle is lifted and the cutting assembly lowered so the blades engage the pavement. The vehicle slides back and forth so the blades cut opposed pairs of sides of slots. Material between each slot is removed with a second cutting vehicle having a cutting assembly with radial blades spaced the same distance apart as the blade pairs of the first vehicle.

Abstract: A seal/retainer unit (10) comprising an annular sealing gasket (12) and a plurality of retaining legs (14) extending generally perpendicularly therefrom. The sealing gasket (12) and the retaining legs (14) are formed in one piece (e.g., stamped) from a sealing material and dimensioned to allow nesting of a plurality of seal/retainer units (10) in a stacked arrangement. The retaining legs (14) may each include a rounded distal edge (16) to minimize package-tearing and interpart-marking and/or a break-off notch (18) to allow special customization. A radiused corner (20) between the gasket (12) and the legs (14) assures a gap between nested parts.

Abstract: A method and system for the creation or modification of the wear surface of orthopedic joints, involving the preparation and use of one or more partially or fully preformed and procured components, adapted for insertion and placement into the body and at the joint site. In a preferred embodiment, component(s) can be partially cured and generally formed ex vivo and further and further formed in vivo at the joint site to enhance conformance and improve long term performance. In another embodiment, a preformed balloon or composite material can be inserted into the joint site and filled with a flowable biomaterial in situ to conform to the joint site. In yet another embodiment, the preformed component(s) can be fully cured and formed ex vivo and optionally further fitted and secured at the joint site.
