Abstract: The wheel mounting of the present invention is designed particularly for use in cable car structures at intersecting street corners, that is, where the cable is carried around a curve. The structure comprises, briefly, a pair of normally vertically spaced horizontally extending supporting pleats and a vertical shaft fixed to the plates and which journals a cable supporting wheel, the later being thus normally mounted to rotate in a horizontal plane. The structure is intended for mounting in below ground surface at the elevation of and to support the car driving cable. Of particular importance is the provision in mounting of a bearing in the wheel hub surrounding the shaft and which has an outer race at the hub wall of the wheel and an inner race at the shaft, the two races being rigidly clamped to the hub and shaft so as to positively confine the forces imposed on the bearing to those forces which the bearing is designed to withstand without undue heating, wear or deterioration.

Abstract: An improved thermally actuated diffuser is disclosed. The diffuser comprises four thermal sensor actuators. A first thermal sensor actuator is responsive to changes in the room air temperature when cool air is supplied through the duct into the room. A second thermal sensor actuator is responsive to the duct air and is adapted to engage the first thermal sensor actuator when cool air is supplied through the duct and to disengage the first thermal sensor actuator when warm air is supplied through the duct. A third thermal sensor actuator is responsive to changes in the room when warm air is supplied through the duct. A fourth thermal sensor actuator is responsive to changes in the duct air temperature and brings the third thermal sensor actuator into engagement when warm air is supplied through the duct and to disengage the third thermal sensor actuator when cool air is supplied through the duct.

Abstract: An sole having an upper elastomer foam pad supported by an overexpanded honeycomb structure, the overexpanded honeycomb structure made by intermittently bonding ribbons of elastomer and expanding them laterally to produce a honeycomb structure having rectangular cells with the longer opposite walls of the rectangle twice the length of the shorter opposite walls of the rectangle, with the shorter opposite walls of the rectangle being double walls, and with the shorter opposite walls of the rectangle elongated in the direction across the sole.

Abstract: A flexible clasp for removable mounting of a partial dental prosthesis to an abutment tooth is disclosed. The clasp includes a retention arm (42) formed to extend around at least a portion of the side of an abutment tooth (27) to retain the prosthesis in an edentulous space (26). In the improved clasp (41), the retention arm (42) is coupled to the prosthesis at a location in the edentulous space, preferably about one tooth width from abutment tooth (27) so as to cantilever support the retention arm (42) for resilient lateral displacement with respect to the abutment tooth. Preferably, a resiliently displaceable tubular member (51) is mounted to the retention arm (42) which is held to the prosthesis by a clip (43) surrounding the tubular member (51) and arm (42).

Abstract: A method for processing the audio signal in a loudspeaker system prior to delivery to the loudspeaker and the apparatus for such processing is disclosed. Uniform acoustic output with respect to frequency at frequencies below the resonant frequency of the loudspeaker system is achieved by changing the strength of the signal at a constant rate in inverse proportion to audio signal frequencies from a frequency below the resonant frequency to a frequency at least one octave above the resonant frequency. A method and apparatus for limiting the audio signal to prevent distortion is also disclosed.
