Abstract: A load and motion transmitting apparatus is disclosed herein having a housing operably mounting a pair of spaced shafts having parallel turning axes where each shaft has a conical portion tapering in a direction opposite to the conical portion of the other shaft. The rotative movement of the driving shaft conical portion of the pair is transmitted to the driven shaft conical portion via a spherical intermediate drive member held in a movable carriage. The periphery of the conical portions includes hemispherical recesses arranged in circumference rows across the length of each conical portion so that relative velocity of the two shafts is controlled by axial movement of the drive member via the carriage. The carriage encloses a plurality of spherical drive members in a series so that each drive member transfers a driving load or force between conical portions in a serial sequence. The carriage location along the conical portions determines a variety of "gear ratios".

Abstract: Disclosed herein is a method and device for the therapeutic treatment of living tissue to assist in the healing of biological traumas and providing treatment of conditions such as arthritis. Positive square wave current pulses are applied between two electrodes positioned on the skin of the patient, one of the electrodes being provided with a concentric electromagnet to produce a magnetic field which forces the applied current into the tissues being treated.

Abstract: A doppler/range simulator for use in testing aircraft systems based on the rinciple that an ionized gas absorbs microwave radiation and thus becomes raised to higher energy levels, and when falling back to the original energy state the ionized gas re-radiates the absorbed microwave energy. A frequency control simulates a doppler or velocity signal. A voltage or current control simulates the time delay or altitude range signal.The test set is in the form of a light-weight anechoic chamber lined on the inside with energy absorbant material except for the top. Within the enclosure there are positioned near the open top a plurality of parallel - arranged flurescent tubes adapted to be energized with pulsating d.c. to produce a flow of ions in the tubes which flow from one end of the tube to the other. The tubes are excited in parallel so that the ion flow is always in the same direction.
