Abstract: ABSTRACT         The plugging of fluidized solids in long transfer lines is a particularly troublesome problem from an operational standpoint.  Obstructions are cleared by closing off the transfer line at both ends, introducing an inert (non-deleterious) gas into the conduit at a few atmospheres pressure above the pressure at the conduit output, maintaining the gas pressure for a time to allow pressure equilization along the conduit, and thereafter opening the conduit outlet to permit the plugged solids to refluidize and then clear the line.

Abstract: MOS SENSE AMPLIFIER            Abstract of the Disclosure A comparator circuit suitably configured and synchronously operated to distinguish between the levels of two input signals and to provide the relative standing of the levels in binary format.  In one form, a symmetri-cally organized circuit having the fundamental structure of a bistable multivibrator is initially operated in a differential mode and subsequently transitioned to a latch mode.  Appropriate constant current source biasing shifts the differential mode operation to optimize ampli-fier element gain characteristics for the levels of input signals received.  The amplified difference between the two input signals is stored within various capacitive elements of the circuit output stages.  During the differential mode, the bistable multivibrator cross-coupling elements are disabled.  At the termination of the differential mode, the amplified difference between the two input signals provides the initial conditions for the regenerative dynamics associated with the onset of cross-coupling and the transition to the latched state.  Preferably, the input signals and the bias circuit are disabled in synchronism with the cross-coupling operation, to provide a stable output from the multivibrator circuit in conventional binary format.

Abstract: METHOD & APPARATUS FOR THE  CONCENTRATION OF FRUITS                        ABSTRACT         A method of concentrating fruits which preserves the original coloration and freshness of flavor and retains the structural integrity of the fruit for subse-quent preserving or canning operations.  The fruit is first subjected to a high vacuum while adding only enough heat to maintain the fruit at a temperature below the boil-ing temperature of water at the maintained vacuum.  This is continued until foaming caused by the release of air in the cells of the fruit either ceases or is at least com-mencing to be reduced.  The fruit is then moved in a thin layer through a heated, rotating cylinder maintained at the same vacuum to cause the juices in the fruit cells to migrate to the surface of the fruit.  As the cylinder rotates, the juices coat the walls of the cylinder. The cylinder is heated to a temperature above the boiling point of water at the maintained vacuum to boil of this coating.  The speed of rotation and the temperature are so interrelated that at least a major portion of the inner wall of the cylinder is continuously wetted by the coating of juices and the fruit is not tumbled in the cylinder. The process is continued until the desired degree of con-centration has been reached.

Abstract: Abstract of the Disclosure Load Transporting Apparatus Load transporting apparatus enables loads to be transported on and off vehicles.            The apparatus requires a loading platform to be located adjacent a load receiving surface of a vehicle. The platform and the surface each have channel shaped tracks which are aligned with one another.            An inflatable tube on which is carried a plate is located in the base of the channel and skates are arranged to be moved along the plates when the tube is inflated. Thus the skates can move along the channels supporting a load when a transfer to or from the vehicle is required.   When in position deflation of the tubes causes the skates to lower and the load rests on the associated surface. In the deflated position the skates can be moved along the tracks out of engagement with the load.            The plates have a central depression to ensure that the skates remain centrally located in the tracks.
