Abstract: A double-acting hydraulic cylinder and piston rod unit having fluid hoses for conducting fluid thereto. A generally flat outer end is provided on the piston or cylinder. A bracket has a spherical socket and either the piston rod end or cylinder has a spherical ball portion swively mounted in the socket. A yoke has a slot in which the generally flat end is slidably mounted for sliding in opposite directions. The flat end prevents relative rotation between the rod and cylinder about a longitudinal axis. Guide slots are provided and arranged at right angles to the yoke slot, the yoke being slidable in the guide slots whereby the unit can swivel about the socket and can slide in the opposite directions in the yoke and the unit can also move at right angles thereto by sliding with the yoke in the guide slots. The piston rod and cylinder are prevented from rotating relative to one another about their longitudinal axis and thereby prevent twisting of the hoses.

Abstract: A light pipe for a backlight assembly has a front surface and a back surface. The back surface includes an integral surface diffuser microstructure formed thereon. The front surface may also have an integral surface diffuser microstructure formed thereon as well. A backlight assembly has a reflective surface adjacent the back surface of the light pipe and a separate diffuser film layer disposed against the front surface. A pair of brightness enhancing film layers for collimating light are placed adjacent the diffuser film layer. A protective layer is disposed over the brightness enhancing film layers. The integral diffusers on the front and back surfaces of the light pipe significantly enhance the brightness and light distribution uniformity of the assembly without adding additional components or reducing other performance characteristics of the assembly.

The collimator can include an input surface, a paraboloid surface located adjacent to the input surface, a conical surface located adjacent to the paraboloid surface, and an ellipsoid surface located adjacent to the conical surface and located on an opposite side of the collimator from the input surface. The paraboloid surface can include a total internal reflection surface.

Abstract: The pavement patch composition of the present invention comprises a lightweight aggregate and highly modified polymer asphalt binder. The composition is formed by heating the binder to a flowable state, mixing the flowable binder with a lightweight aggregate, and then allowing it to cool into a solid form. The pavement patch composition is used to repair voids in pavement, such as pot holes, cracks and depressions. It is applied by heating solid pavement patch composition to a flowable state and applying it to the void, or on a surface in need of repair, and then allowed to cool. The resulting patch is self-adhering, strong and flexible. The formulation of the pavement patch composition may be adjusted for specific use in a cold climate, a moderate climate, a warmer climate, or for use in various traffic applications.

Abstract: Local sensitive force detector output data, acquired from a cellular and sub-cellular structures (“biological structures”), are quantified in an objective format. Data are acquired from two axes of the biological structure at scan positions along a third axis of the biological structure, which is perpendicular to the two axes. Data are then quantified as a function of scan position along the third axis. The quantified data can be plotted and displayed to generate a two-dimensional representation of a biological structure's morphology, which contains quantified data points from along the third axis of the biological structure. The output can be used for morphology-based classification and typing of biological structures. The invention classifies and types biological structures by converting the local sensitive force detector data into a graphical fingerprint, which, for example, can be compared to standard data generated from known biological structures.

Abstract: A glass diffuser is fabricated by first producing a metal shim submaster or other high temperature resistant diffuser having a surface relief structure on one surface. A glass substrate material is heated to a suitable temperature and at least one exposed surface is thereby softened to a desired degree. The submaster diffuser, and particularly the surface relief structure, is then placed in contact with the exposed and softened glass substrate material in order to replicate the surface relief structure in the glass material. The submaster diffuser and the glass substrate are separated and then the glass is allowed to cool to form a glass diffuser.

Abstract: A vehicle light assembly includes a lens cover from which light emanates. A light shaping surface microstructure is carried in a portion of the light assembly. The microstructure can be incorporated into many different surfaces of the light assembly such as a surface of the lens cover, a surface of a macro-optical structure on the lens cover, or on a reflective surface of the assembly. The microstructure homogenizes and directs light emanating from the light assembly via reflection or transmission to provide a smooth, continuous pattern of light having a predetermined distribution shape or envelope and a predetermined directionality.

Abstract: A system and method for real time optical processing of images by simultaneous combining the variable set of images in selected spectral intervals. Spectral images at a plurality of spectral intervals are collected if needed. According to criteria established in a particular application, coefficients for an optimal combination of selected spectral intervals are calculated. Positive and negative images are continuously captured through the optical filter whose transmission spectrum adjusted to positive and negative coefficients of the optimal combination. Negative images are subtracted from positive images and a sequence of resulting optimized images is displayed in real time.

Abstract: A high degree of measurement reproducibility is assured for the life of the tip of a probe-based instrument such as an atomic force microscope (AFM) by periodically operating the instrument in a tip cleaning mode to remove contaminants from the tip. The instrument is operated to interrupt the scanning operation and cause the probe to interact with the cleaning medium so as to remove contaminants from at least the pointed end portion of the tip. Tip cleaning may be achieved, for example, by ramming the tip vertically into the sample itself or into another cleaning medium located adjacent the sample. Alternatively, the tip can be moved laterally over the sample, a sticky material, a brush-like material, a ribbed material, or another material having surface characteristics that remove contaminants from the tip.

The diameter ratio between the inner diameter of the filling hole and the outer diameter of the spherical surface of the steel ball is set to a value falling in a range from 0.6 to 0.85.

Abstract: In a refrigerating cycle with a by-pass line 5 detouring the condenser 2 in an auxiliary heating mode the amount of circulated refrigerant is controlled in accordance with load, etc. so that the heating can be suited to such conditions. A regulator 20 for controlling the outlet pressure of the evaporator to a fixed level allows to use an evaporator 4 having ordinary pressure resistance. An accumulator 6 for temporarily storing low-pressure refrigerant liquid is provided between the outlet of evaporator 4 and a compressor 1. In an auxiliary heating mode the amount of the circulated refrigerant passing the by-pass line 5 is controlled by the accumulator 6. Simultaneously the regulator is controlling the outlet pressure of the evaporator to an essentially fixed level.

Brackets are provided for supporting one or multiple idler rollers on such a frame. One form of such brackets has a tab for retaining the shafts in the end bracket that can be precisely bent over the shaft end by providing a cut that extends generally at right angles from a slot. The adjacent ends of a center and an outer roller shaft in a center combined bracket are retained by a single tab that can be bent into locking position over adjacent ends of the shafts. A conveyor return bracket can be utilized either as a left- or right-hand bracket or it can be used as a simple rise bracket. This return bracket uses novel shaped flanges which act to position the shaft in an enlarged portion of the slot, then the slotted portion of the shaft is pressed into holding engagement in the narrow portion of the slot.
