Abstract: A cable management system and method for winding on or letting out a length of cable from a cable support apparatus, in a generally curved, figure eight path, to prevent continuous twisting of a fixed length of cable coupled between the cable support apparatus and a fixed device. A control system is used to move the cable support apparatus in the figure eight path. The cable support apparatus includes a pair of spools which are arranged at a generally 45° angle to one another. Cable is alternately wound onto or wound from the two spools as the apparatus is moved in the figure eight path.

Abstract: A system for monitoring a condition such as tire air pressure where the monitor at each tire is remotely energized by radio waves, there being two embodiments disclosed for effecting this. A loop antenna concentrically mounted with respect to each tire receiver and/or transmits electrical energy to the remote location which is typically at the operator's console. Each pressure sensitive device is mounted away from the valve stem and may include a strain gauge mounted on the tire side wall or between the wall and rim. An infra-red detector may also be employed as a pressure monitoring device.

Abstract: Method and apparatus for measuring mass flow, and particularly the sum or difference in mass flow of distinct streams of flowing materials, wherein a plurality of channels are provided in one or more conduits rotating or oscillating as a common unit with additive streams or a common stream being flowed through the channels in a first direction and subtractive streams being flowed through the channels in an opposite direction, and in which the net Coriolis force imposed upon the conduit unit is measured.
