Abstract: The method employs attaching two handle/jaw pieces together with a third coverplate piece thereon in the hinge area so that a flange surface of the coverplate opposes a flange surface of one of the handles. A flange surface on the second handle similarly opposes a second flange surface of the first handle. These opposing flange surfaces together creates a type of modified box joint that is robust, accurate, and capable of simple disassembly. A joint in combination with a hand tool that employs this method.

Abstract: A method and apparatus for determining the fluorescence, luminescence, or absorption of a sample is provided. The sample may either be contained within a cuvette or within one or more sample wells within a multi-assay plate. A combination of a broadband source, a monochromator, and a series of optical filters are used to tune the excitation wavelength to a predetermined value within a relatively wide wavelength band. A similar optical configuration is used to tune the detection wavelength. An optical scanning head assembly is used that includes mirrored optics for coupling the excitation source to the sample and the emitted light to the detector. An elliptical focussing mirror is used to magnify and focus the light projected from an optical fiber coupled to the source subassembly onto the sample. A portion of the source light is reflected by a beamsplitter onto a reference detector used to monitor the output of the source.

The sample may either be contained within a cuvette or within one or more sample wells within a multi-assay plate. A combination of a broadband source, a monochromator, and a series of optical filters are used to tune the excitation wavelength to a predetermined value within a relatively wide wavelength band. A similar optical configuration is used to tune the detection wavelength. In one aspect, multiple optical fibers are coupled to the excitation source subassembly, thus allowing the system to be quickly converted from one optical configuration to another. In another aspect, the excitation light and the detected sample emissions pass to and from an optical head assembly via a pair of optical fibers. The optical head assembly is scanned across one axis of the sample multi-assy plate.

A similar optical configuration is used to tune the detection wavelength. In one aspect, multiple optical fibers are coupled to the excitation source subassembly, thus allowing the system to be quickly converted from one optical configuration to another. For example, the source can be used to illuminate either the top or the bottom of a sample well within a multi-assay plate or to illuminate a single cuvette cell. Similarly, multiple optical fibers are coupled to the detector subassembly.

Abstract: A fixture for controllably holding a blade and particularly a scissor or scissor element for precise sharpening and shaping including hollow grind and clamshell (convex) sharpening. The fixture comprises an articulable holding arm with at least two movable joints and an extension portion swivelly attached to one of the joints. The extension portion terminates in a holding member for the scissor or scissor element which holding member is freely concentrically rotatable relative to the longitudinal extension axis of the extension portion. The holding member comprises a clamping element for holding the scissor element parallel to the longitudinal extension axis. The extension portion further comprises a position adjustable stop to limit rotation of the holding member to provide a precise angular holding of the scissor element relative to an adjacent sharpening element.

Abstract: A remote control device is designed to be worn on one arm and operated by movements of a single hand. The device includes a forearm section and a pivotally connected hand section. The device is capable of providing up to 8 channels of individual controls. Both radio transmission and wire transmission capabilities are disclosed. The device includes switches that can be actuated by hand movements in either of two axes and also by a rotary movement of the hand relative to the forearm.
