摘要： A pocket joint cutter system for forming a pocket cut and fastener bore into a workpiece. The pocket cut and fastener bore receives a fastener such as a self-tapping screw which passes through the bore and into a second workpiece for forming a Joint between the two workpieces. The head of the fastener is held within the pocket cut in order to secure the joint. In one preferred form of the present invention, a workpiece system secures the workpiece in a predetermined position and forms the pocket cut and fastener bore into the workpiece. This preferred embodiment further comprises a bench-mounting system coupled to the workpiece system for securing the system to a bench. Using this embodiment of the present invention, the system can be mounted to a bench, and the workpiece can be brought to the system and held in position while the user forms the pocket cut and fastener bore. In an alternate form of the present invention, the system comprises a pocket cutter system for forming the pocket into a surface of the workpiece and a drill guide system for guiding a drill bit in order to form the fastener bore into the pocket at an orientation which is perpendicular to a joint surface of the workpiece. With such a perpendicular orientation of the fastener bore, the two workpieces are less inclined to creep up or down with respect to one another, in contrast to systems which position the fastener bore at a non-perpendicular angle to the joining interface between the two workpieces.

摘要： A multiple axle trailer comprises a chassis pivotally connected to turn substantially horizontally with respect to a sub-chassis and provided with means at its forward end to enable the trailer to be hitched to a towing vehicle, the sub-chassis carrying forward and rear pairs of wheels. An adjustable length steering arm is pivotally connected to the sub-chassis and to the chassis forward of the connection to the sub-chassis. A system of linkages connects the forward wheel king pins with a mounting point which is rotationally fixed with respect to the steering arm and operates to turn the forward wheels from the steering arm so that the trailer tracks the towing vehicle. In a preferred embodiment the mounting point is moveable longitudinally to enable the forward wheels to be moved in the opposite direction during reversing of the trailer.

摘要： A frequency domain spectrofluorometer employing extrinsically modulated DC light sources or intrinsically modulated laser pulse trains, containing multiple, harmonically related, phase-locked frequencies for exciting a fluorescent sample. High frequency light emissions of the excited sample are simultaneously cross-correlated with multiple, harmonically related, phase-locked R-F frequencies to produce workable low frequency electrical detector signals having the same phase and modulation characteristics as the multiple frequency sample light emissions. The detector signals are digitized in a computer and transformed from time to frequency domain by complex fast fourier transforms to extract the phase and modulation data for all frequencies of the sample light emissions. This data is displayed simultaneously on the visual presentation screen of the computer.
