Abstract: A mechanically joined steering assembly for supporting the wheel of a wheeled vehicle for steering movement relative to the frame of the vehicle. The steering assembly includes a crown attached by mechanical fasteners to blades and to a central steering portion joining the assembly to the frame of the vehicle. The parts joined are the blades (16), steerer (14), crown (12), and reinforcements (24). Mechanical fasteners serviceable with common tools provide a reinforced steering assembly of greater strength than welded or brazed constructions. This assembly allows the use of metallic, advanced composite, or thermoplastic components. Adjustments of axle location and steering geometry are made by sliding blades (16) up or down in crown (12). Blades (16), steerer (14), and crown (12) retain the original cold drawn strength of the metal used by mechanically joining without brazing or welding.

Abstract: A machine tool comprises two motion units, in particular a spindle stock and a machine bed, arranged for being displaced relative to each other along one axis. A guideway is fixed to a first motion unit for guiding the displaceable motion unit, a first surface of the guideway being in contact with, and screwed to a second surface of the first motion unit. In order to prevent the guideways from being dislodged in a direction perpendicular to the longitudinal axis of the machine screws, for example when the spindle stock runs up against a stationary obstacle due to improper operation, at least one of the said surface is roughened.

The bracket which holds the seat tube preferably also holds the top tube.

Abstract: A non-intrusive DC current monitor is presented which emulates the theoretical operation of an AC transformer. A conductor, carrying the current to be measured, acts as the primary of a DC current transformer. This current is passed through the center of a secondary coil, and core positioned thereabout, and produces a magnetic flux which induces a current in the secondary proportional to the current flowing in the primary. Means are provided to periodically "reset" the transformer core such that the measurement inaccuracies associated with core saturation are obviated. A reset current is caused to periodically flow through the secondary coil which produces a magnetic flux oppositely polarized to the flux created by the current in the primary, thus allowing ongoing measurements to be made.

One or more semiconductor chips are bonded to individual assembly sites on the leadframe, after which the lead-die assembly is encapsulated by transfer molding. The cap and leads are singulated, and a bobbin is attached to the leads, which extend laterally from each individual molded cap. In an automated process, a conductive wire is attached to a first of the protruding leads, fly-wound around the bobbin core, and terminated by connection to a second of the protruding leads.

Display means are provided to indicate this distance and location.

Abstract: A resilient panel having anisotropic flexing characteristics in which thermal compression bonding techniques have been to laminate a plurality of sheets of thermoplastic polyurethane material together with bonds that are in strip form, spaced at regular intervals, and staggered between alternate sheets of material. The laminated stack was then cut into slices of appropriate thickness, and the slices were expanded to form a honeycombed core which, while held in spread apart disposition, was thermally pre-formed and made ready to receive facing materials. The facing materials were then thermal compression bonded to each side of the honeycombed core, and the panels were trimmed to assume their final dimensions.

Abstract: An improved catadioptric imaging system is presented which produces a flat accessible final image, and is particularly effective at high speed in the deep ultraviolet spectral range. The lenses of the system are formed from a single glass type, fused silica. A first group of lenses serves as an aberration corrector group. A single focusing lens focuses light, transmitted through the corrector group, forming an intermediate image at a predetermined position within the system. A separate field lens is placed at the intermediate image point, and focuses the light transmitted thereto through a hole in the center of a spherical mirror. The light then travels through a separate thick lens element and is subsequently reflected by a planar mirror back through the thick lens and towards the concave reflective side of the spherical mirror. The spherical mirror thereafter reflects this incident light, focusing it through a hole in the center of the planar mirror and to a final imaging point outside of the system.

Abstract: A microstrip antenna including an orthogonal planar array (12) of patch radiators (10) with specially configured feed boards (16) provided for each column of array elements. Each such board includes a portion disposed parallel to the plane of the array and one or more portions bent or folded to extend in the direction of the array axis for a distance sufficient to accommodate necessary circuitry (36) and active devices (40). A metal supporting frame (18) serves both as a common ground for the assembly and as a heat sink for conducting some of the heat generated by the active devices mounted to the feed boards. An additional planar circuit board (22) is positioned beneath the supporting frame to accommodate the power combining circuit and to interconnect all of the elements. Connection between feed boards (16) and combiner board (22) is accomplished using via-connections or a coaxial cable network.

Abstract: Edge enhancement method and apparatus for dot matrix devices wherein a group of gradient mask matrices are applied to a "current matrix", wherein a TBAP (To Be Adjusted Pixel) is surrounded by neighboring pixels, to determine if the TBAP is at a location where a change of brightness occurs. From this matrix operation, a conclusion is derived as to the existence or non-existence of an edge and the direction of the brightness change. The current matrix and a predetermined number of previously evaluated and yet to be evaluated pixels are then compared to a set of reference bit patterns which depict possible segment changes to be corrected. If the result indicates that the TBAP is on an edge of a changing edge segment, a corresponding code will be generated to modify the TBAP to enhance the smoothness of a segment transition.

A ferrite core is attached to the base of the cap, and a fine coil wire, dispensed from a specially designed applicator, is automatically bonded to one of the leads protruding from the cap body. The wire is subsequently wound around the ferrite core and terminated by automatic attachment to another of the protruding leads. The assembled device is thereafter encapsulated within a small glass housing.

When two or more containers are stacked, the ridges on the top of the supporting container will interdigitate with the ridges on the underside of the mounted container to align the containers squarely atop each other and to inhibit longitudinal and lateral movement of the stacked containers. Each container has a drawer lock for security.
