Abstract: The cockpit and external appearance of a racing car are accurately simulated. A spherical mirror display is attached to the underside of the hood of the simulator. When the hood is raised, a video presentation is projected onto a display screen via first and second mirrors and the image on the display screen is reflected off of the spherical mirror to the player “driving” the simulated racing car. In the preferred embodiment, the spherical mirror is a thin acrylic sheet molded to the desired curvature. A mirror surface is formed on the concave surface of the molded sheet and a sheet of foam plastic is scored on one side so that the foam plastic sheet conforms to the reverse concave side of the molded acrylic sheet. The foam sheet is molded to the thin acrylic sheet mirror to rigidly support the acrylic sheet mirror in the desired curvature.

Abstract: An improved method and apparatus for processing deleterious material on a floating vessel during transportation from a well to a disposal site. The vessel contains equipment for the slurrification and agitation of the deleterious material. Such equipment includes storage tanks, slurrification units, and agitation units, as well as transfer equipment such as flow lines and vacuum or pump means. The deleterious material is transferred from the drill site to the storage tanks on the vessel. The vessel then transports the material to a disposal site, such as an injection well. During transportation, the deleterious material is processed. Such processing can include slurrification and/or agitation of the deleterious material to maintain the slurry, adding fluid if necessary. Once at the disposal site, the deleterious material slurry is then transferred from the vessel to the disposal site.

Abstract: A knock-down bookcase and shelf unit includes a pair of upright mirror image side members and a plurality of shelves which extend through relatively large openings in the side members, with the shelves being supported on the bottom edges of those openings so that the shelves lie in horizontal planes. Abutments are provided to prevent the shelves from shifting laterally relative to the side members. Also, an elongated, flexible resilient slat is positioned under each shelf with the opposite ends of the slat engaging in slits in the side members. Other abutments are provided to maintain the slats in a bowed condition so that the slats exert outward forces on the side members thereby stiffening the unit as a whole while supporting the shelves from below.

Abstract: A mirror for domestic use in the bathroom or kitchen having electric heating means in the form of a resistance heater having a positive temperature coefficient of resistance and being an elongated cable supported by a molded plastic member in direct contact with the rear surface of the mirror.

Abstract: An article of folding furniture such as a stool or a table is made from board or other sheet material by a few cutting operations that provide substantially all the load bearing parts necessary for the complete unit. When assembled, the furniture article exhibits symmetry about the folding axis and its parts complement one another so that when the article is folded, the parts interfit to form a flat compact package. Resultantly, the article can be stored singly in a confined space or in numbers in a compact stack.
