Abstract: In a microscope viewing apparatus for viewing a specimen image, the provision of microscope viewing apparatus including a microscope eyepiece lens for focusing on a focusing plane at or above a specimen support panel and coincident with a desired viewing plane of a real microscopic specimen positioned therein, arranged to generate a specimen image, and the further provision of separate overlay pattern image-generating apparatus arranged to optically effectively generate a desired type, shape and size of optical overlay pattern and image, and the further provision of optical-image-mixing and combining apparatus arranged to receive the specimen image and the optical overlay pattern image and to effectively mix and combine same into desired selectively optically alignedly effectively centered and superimposed relationship to form a resultant effectively visually composite image output for effective viewing by the microscope viewing apparatus.

Abstract: An improved portable field inspection microscope intended primarily for, but not in all cases limited to, use in inspecting butt ends of fiber optics cables, or other similar cylindrical objects, and including a receiver, holder and positioner adapted to receive such a butt end of a fiber optics cable, or the like, and to position same coincident with a selected butt-end-surface-viewing plane, which may also be considered as a microscope focusing plane, which lies appropriately forwardly of a microscope optical-path-defining longitudinal cylindrical inner chamber in a small portable housing and which not only carries said receiver, holder and positioner at a forward location, but intermediately carries microscope objective lens mounting apparatus and a microscope objective lens assembly for focusing on said focusing plane, and with the housing also being further rearwardly provided with microscope eyepiece lens mounting apparatus and an eyepiece lens assembly longitudinally adjustably carried for focusing on,

Abstract: Positioning apparatus for positioning a workpiece holder relative to a frame of reference and with the workpiece holder in a preferred form being intended to mount and hold a workpiece comprising an eyepiece and/or objective lens portion of a microscope optical system in a vertical position such as to align an optical axis of the microscope eyepiece and/or objective lens portion vertically with an optical axis of the rest of the microscope optical system which is adapted to be carried by a microscope stand which extends upwardly to the level of the workpiece holder and is effectively attached with respect thereto by an adjustable positioning head having an attachment portion and an adjustably movable coupling portion having a connection part cooperable for connection to the workpiece holder and with the attachment portion and the coupling portion being provided with controllably adjustable relative movement-causing apparatus effectively interconnected therebetween in a manner such as to selectively and contro

Abstract: Warning-signal producing apparatus and system for a first motor vehicle responsive to a vehicle-presence-indicating radio wave signal produced by and emitted from a second motor vehicle within a certain distance of the first motor vehicle for effectively causing the production of a corresponding warning signal within the interior of the first motor vehicle and, in one form, for correspondingly attenuating, muting, or interrupting sound emitted by any simultaneously operating intertainment apparatus within the first-mentioned-motor vehicle.

Abstract: A clamp hand protector for use on a pivoting type clamp having an operating handle member pivotally connected to a linkage element of the clamp and defining therebetween an arcuately-variable-angle junction region, wherein an edge-of-hand protective shield is provided with mounting means for positioning the shield between an inner end of the operating handle member and the arcuately-variable-angle junction region so as to prevent injury to an operator's hand when the clamp is moved between clamped and unclamped relationship or vice versa.

Abstract: An improved microscope stand of an extremely rigid, deep-throat, substantially c-shaped, hollow construction having an extremely high effective modulus of elasticity and stiffness of an extended microscope-optic-supporting upper cantilever arm relative to a lower base portion whereby to minimize any relative vertical displacement therebetween which might tend to produce a de-focusing action of such microscope optics and adapted to controllably positionally adjustably mount a large work stage in an intermediate focusing plane within a deep-throat portion of the stand, and providing controlling large magnitude movement thereof in mutually perpendicular, substantially horizontal, x and y directions, and with the hollow construction providing interior mounting of electrical and electronic accessory equipment and maximizing the strength-to-weight ratio of the entire stand.

Abstract: A multi-directional aerosol valve for use on a pressurized aerosol container (usually a can) to provide for substantially completely emptying such an aerosol can in any selected one of multiple directions, usually ranging between the conventional lateral direction and a vertical direction and, in certain cases, including various different angular directions lying therebetween. This type of multi-directional valve makes it possible to emit the aerosol spray in a variety of different directions and greatly facilitates and broadens the scope of its applicatory usage.
