Abstract: A method of generating a machining program that can be interpreted by a physical controller of a numerical control machine tool. The machining program is generated from a prerecorded set of machine parameters representative of the machine tool, and a prerecorded set of machining sequences on the basis of at least some of the said machine parameters and of at least some of the machining sequences, a computer simulation program carries out machining feasibility tests (TST), the machining program being generated in a format that can be executed by the said physical controller only if it passes the machining feasibility tests beforehand.

Abstract: Foam construction (1) for use in a mattress or pillow, that comprises a base (2) extending in a longitudinal direction (L) that is made of a flexible synthetic foam, whereby this base (2) comprises two arms (4) extending in the longitudinal direction that are connected by a breathable bridge (5) that extends in the said longitudinal direction (L).

Abstract: Provided is a system and method for protecting and restoring a surface by applying thereto a preformed polymer based film and securing the film to the surface. Particular application is found where the surface is a deck surface.

Abstract: The present invention relates to a vibration control or vehicular suspension system. In one embodiment, the system uses a liquid spring filled with a compressible liquid. In such an embodiment, a suspension system, in addition to being able to change stiffness and damping properties, has the ability to level a vehicle or other structure or device to a desired height and compensate the level height for the addition or subtraction of load. Further, the liquid spring can provide either spring force or both spring and damping forces.

Abstract: Provided are polyurea/polyurethane based films and coatings which are imaged by a dye sublimation technique, and the method for imaging same.

Abstract: A non-contact light emitting display for a vehicle is disclosed as having at least: a light emitting unit, a first induction coil to supply electric power for the light emitting unit; the first induction coil generates electric power by non-contact induction with an inductor of the vehicle for executing one way or two way signal transmission. Thereby, the non-contact light emitting display can save the provision of exposed electric conductors or conducting pins, it can obtain electric power from the vehicle to execute one way or two way signal transmission, or can be used on an aeronautic, a space or a sea vehicle for illumination with the effect of water proofness and dust proofness.

Abstract: An aliphatic hybrid polyurethane/polyurea protective coating intended for use on concrete, steel, wood and other surfaces is provided, which coating exhibits excellent properties of durability and flexibility. The protective coating uses chemical components from urethane/urea systems in a unique way to generate beneficial systems.

Abstract: A vehicle suspension system comprises a combination of cantilevered spring members which extend in opposite directions across the front and rear ends of the vehicle and are supported between upper and lower bearing members which are spaced to regulate the degree of resistance to roll or cornering loads both at the front and rear end suspensions. Novel and improved A-frame assemblies with toe and camber adjustments are provided at the front end of the system, and outboard extensions are provided at the rear end to increase the effective span or extension of the spring members in countering any tendency of the vehicle to roll.
