Abstract: A device for use with a wood-based structural element having an outer surface and inner surfaces defining a T-slot, wherein the T-slot has a central section that is open at the outer surface, and has a pair of undercut sections projecting from opposite sides of the central section, and the inner surfaces of the structural element include a pair of inner surfaces facing inward, the device comprising: a T-nut having an outer portion receivable in the central section of the T-slot, a screw-threaded bore, and an inner portion with a pair of clamping surfaces projecting from opposite sides of the outer portion; wherein the bore has a nominal cross-sectional area for receiving a threaded fastener, and the clamping surfaces on the T-nut have a combined surface area of about 10 times the cross-sectional area of the bore; and wherein the T-nut is configured for use with a wood-based structural element.

Abstract: A fixturing system for woodworking includes a woodworking table having a planar top surface and a T-slot. The T-slot has a central section that is open at the top surface, and further has a pair of undercut sections projecting laterally from opposite sides of the central section. The table has a pair of inner surfaces facing downward over the pair of undercut sections of the T-slot. The system further includes a T-nut. An upper portion of the T-nut is receivable in the central section of the T-slot, and has a screw-threaded bore. The bore has a nominal cross-sectional area for receiving a screw-threaded shank on a fastener. A lower portion of the T-nut has a pair of clamping surfaces projecting laterally from opposite sides of the upper portion. The clamping surfaces on the T-nut have a combined surface area of at least about 4 times the nominal cross-sectional area of the bore.

Abstract: A system for adapting existing conventional screw machines to be capable of computer numerical control operation. The system incorporates the use of a VersaCam device which replaces the turret cam of a single spindle screw machine. The VersaCam system monitors the motion of the screw machine camshaft and actuates the turret slide in synchronization with the camshaft. The VersaCam system also provides a means of specifying the desired turret slide trajectory for any given job.

Abstract: A generally flat, rectangular rubber pad supports (63) discrete, non-invasive electrodes in a 7 by 9 array and a ground electrode to collect surface electromyographic (EMG) signals from an underlying muscle group of a patient. Electronic apparatus conditions the EMG signals and is programmed to survey the electrode array simultaneously to provide a description of the activity of individual muscles in the muscle group at that point in time. The description is displayed on a video monitor or the like, juxtaposed over a display of normal muscle anatomy, with differences being emphasized by color enhancement. The electrode pad is particularly suited for the lower back muscle groups and may be retained in position by a lumbar support belt having a pad molded to the contours of the human spine.

Abstract: An industrial mobile process monitoring system is described which provides a means by which a measurable atmospheric condition, such as temperature, can be measured in real time at a plurality of different locations in a structure such as a kiln, and the information transmitted to a base station computer via magnetic energy linking primary and secondary windings of an air-core transformer.
