Abstract: A mirror surface for mounting onto an exterior front fender of a vehicle. The mirror surface is a portion of a convex surface ellipsoid with a plurality of radii of curvature. The mirror provides the driver of the vehicle with a field-of-view that is greater than the reflection angle about the vertical axis. The reflective surface has a generally convex shape throughout. The reflective surface a viewing center point that is in general alignment to the geometric center of the reflective surface. The reflective surface is generally symmetrical about a vertical plane passing through the viewing center point and about a horizontal plane passing through the viewing center point.

Abstract: A vehicular mirror clamping bracket used for securing mirror assemblies to a vehicle. The clamping bracket is a base and a clamp unit hinged to open and close, thus, permitting a support for a mirror assembly to be inserted into a throughbore within the bracket. The clamp is closed over the mirror assembly support applying torque and thereby holding the support in place. When the clamp is closed, a latch hook on the clamp engages a latch edge in the base thereby locking the clamp closed.

Abstract: The invention is a process for selectively adsorbing nitrogen from a gas mixture which comprises contacting the gas mixture with an adsorbent that has a moderate nitrogen capacity and a high selectivity for nitrogen over the other components in the mixture. With respect to air separation, improved adsorbents have low O.sub.2 capacity with N.sub.2 capacity at roughly the same level as current adsorbents such as CaA. O.sub.2 VSA computer process simulations have shown the unexpected result that for materials with the same binary isothermal working selectivity, those with lower isothermal nitrogen working capacity are superior O.sub.2 VSA adsorbents, provided that they have a nitrogen working capacity of at least about 0.3 mmol/g.

Abstract: A combination sun visor and rear view mirror assembly includes a mirror, a mirror housing, and a bracket for attaching the housing to a vehicle. A sun visor panel is pivotally attached to the bracket and is rotatable about the mirror. The visor may be oriented above the mirror, below the mirror, or may be cover the mirror to shield the driver of the vehicle from a direct reflection of the sun. The visor is preferably formed from a tinted, translucent material.

Abstract: The mounting assembly readily enables longitudinal or transverse adjustment of the position of the mirror relative to the vehicle. The mounting assembly includes a mirror shaft, a base member and a cover member to secure the upper end of the mirror shaft to the back of the mirror; a pair of anchors and sleeves which anchor the medial portion of the mirror shaft to the vehicle, and a clamping member and a bracket member to mount the lower end of the mirror shaft to the vehicle. The mirror shaft is secured within the clamping member, the clamping member is mounted onto the bracket member, and the bracket member is mounted onto the vehicle. The base member is secured to the back of the mirror, and the upper end of the mirror shaft is securely retained between the cover member and the base member. Two elongated anchors are cooperatively engaged with two sleeves which are medially disposed about the mirror shaft.

Abstract: The mirror assembly of the present invention includes a frame which house the mirror, a mirror frame, a rigid tubular member, and means for mounting the mirror frame to the vehicle. The mirror assembly is for mounting onto an exterior front surface of a vehicle, preferably, in the shape of a one-fourth of an ellipsoid. The mirror surface is in the shape of a convex triangle, having a variable radius of curvature. The mirror is in the shape of a portion of a quadratic surface. The mirror is formed by the intersection of each of two parallel planes with the quadratic surface. The mirror surface has a plurality of radii of curvature. The mirror provides the driver of the vehicle with a field of view which is substantially greater than angle of the quadratic surface about a vertical axis. The top portion of the ellipsoid which provides a field of view over the driver, and the side of the ellipsoid which provides a field of view of the front of the vehicle are eliminated from the mirror surface.

Abstract: The invention involves a new mirror assembly for large vehicles that enables a mirror to be mounted upward from the vehicle in a first orientation providing a field of view adjacent to the vehicle, and readily adjusted into a second orientation wherein the mirror is outward from the vehicle providing a field of view for behind the vehicle. The assembly includes a rear-view mirror assembly comprising a mirror, a mirror housing, a bracket for mounting the assembly to a vehicle, and a linkage connecting the bracket to the housing. The linkage can be easily rotated relative to the bracket. The mirror housing can be readily disengaged from and reengaged to the linkage thereby enabling a reorientation of the assembly relative to the vehicle. By so doing, an oblong mirror can be mounted to the vehicle in one orientation for driving, disengaged and reengaged in a second orientation for rearward movement of the vehicle.

Abstract: A mirror assembly for mounting onto an exterior front surface of a vehicle, preferably one on each opposed front fender of the vehicle. The mirror assembly includes a mirror having a reflective surface, the surface having a generally convex geometry, and being in the shape of an ellipsoid. The reflective surface provides the driver with a field of view along the vertical axis is in the range of 180.degree. to 220.degree.. The top portion of the reflective surface has a first plane of truncation which passes through the approximate center of the reflective surface. The rear portion of the reflective surface has a second plane of truncation which removes at least the rear half of the surface. This second plane is essentially normal to the first plane of truncation. The reflective surface is mounted with a slight upward tilt.

Abstract: An improved pressure swing adsorption process is disclosed for the recovery of two individual components from a multicomponent gas mixture. The process utilizes a first group of adsorbent beds selective for the secondary component product and a second group of beds selective for tertiary impurities in the mixture. The gas mixture is passed through the first and second beds in series and high purity primary component product is discharged from the second beds. The secondary component product is recovered by desorption from the first beds. Product recovery is improved by recycling depressurization gas from the first beds and by several novel pressure equalization steps. The process can be used to recover high-purity hydrogen and carbon dioxide from a gas mixture containing these components along with minor amounts of methane, carbon monoxide, and nitrogen.

Abstract: A process is described for recovery of a more selectively adsorbed key component from a gas mixture containing the key component and one or more less selectively adsorbed secondary components using vacuum swing adsorption. The process minimizes capital costs by reducing or eliminating gas storage vessels and reduces power requirements by operating without a feed compressor or elevated pressure feed, whereby feed is induced at least in part by vacuum conditions achieved by pressure equalization between parallel adsorption beds. Alternatively, at least a minor amount of less selectively adsorbed secondary component roduct can be recovered.

Abstract: A mirror mounting apparatus for having two separate mounting assemblies. The first mounting assembly mounts directly to the vehicle. The second mounting assembly with attached mirrors mounts on the first mounting assembly. A clamping bracket or brackets having to separate pieces is insertable in one or more slots of the second assembly to clamp the first and second assemblies together.

Abstract: A dual outside mirror assembly for mounting dual mirrors on a vehicle door having a window includes a two part tubular frame in which an upper tubular frame member may be rotated about a vertical axis relative to a lower tubular frame member whose lower end in turn is mounted for rotative adjustment relative the vehicle door about the same vertical axis. The upper frame member is mounted on the vehicle door above the window for rotative adjustment about a horizontal axis to enable the frame to be conformed to doors of various configurations. The tubular frame includes a vertically extending offset section upon which two mirrors are mounted one above the other for rotative adjustment relative to the tubular frame about at least one vertical axis and independently about individual horizontal axes.

Abstract: A process is described for nitrogen recovery from air using vacuum swing adsorption.

Abstract: A process is described for the separation of an off-gas from a synthetic fuels production process, such as oil shale retorting, coal gasification, oxygen fireflooding or carbon dioxide miscible flood enhanced oil recovery, into an essentially sulfur-free, light fuel gas and a sulfur containing carbon dioxide gas. The off-gas is contacted with methanol to remove the sulfur containing gases and is then cooled to separate out a light fuel gas from a predominantly carbon dioxide gas. The carbon dioxide gas is again contacted with the same methanol to scrub the latter of sulfur-containing gas and reabsorb the sulfur onto the carbon dioxide gas. The carbon dioxide gas can then be recycled to the synthetic fuels production process with deposition of the sulfur therein or the gas can be delivered for export with downstream sulfur treatment.

Abstract: A process is disclosed for the separation of carbon dioxide and sulfide gases from oil shale retort off-gases, coal gasification off-gases, oxygen fire-flooding or carbon dioxide miscible flood enhanced oil recovery off-gases for recycle to a retort, gasifier or petroleum reservoir or alternately delivery to another process. The process separates the off-gases into an essentially sulfur-free fuel gas and an acid gas for recycle to such a retort, gasifier or reservoir wherein the off-gas is compressed if necessary and cooled to separate the two streams, the acid gas is expanded in an auto refrigeration step to provide the necessary process refrigeration and the acid gas is then recycled to such a retort, gasifier or reservoir. In the oil shale retorting and coal gasification applications, the gas' sulfur constituents are sorbed on spent oil shale particles or coal ash.
