Abstract: ACTUATING VALVE                   Abstract of the Disclosure An actuating valve serves as a pilot to a control valve for a valve controlled flushing system for a tank-type toilet installation which comprises a siphon flush valve, and a control valve that allows supply water to flow into the tank to initiate siphonic action, to supple-ment flow through the siphon flush valve and to refill the tank, which control valve utilizes a piston which is ordinarily seated in a closed position by supply line pressure.  The actuating valve is located in a bypass passage between the supply pressure and a timing pressure chamber of a control valve.  The actuating valve comprises a triggering mechanism, a valve housing, an internal passageway through the valve housing for the flow of supply water and the transfer of supply line pressure, valve means positioned in said housing which upon acti-vation of the triggering mechanism interrupts the flow of supply water and the transfer of supply line pressure through the passageway until the pressure on the piston of the control valve is relieved, the timing pressure chamber is emptied, and the control valve is opened to initiate a flushing cycle and means for disengaging the triggering mechanism to prevent premature or improper use from interfering with the completion of the initiated flushing cycle.

Abstract: GRINDING AS A MEANS OF REDUCING FLOCCULANT REQUIREMENTS FOR DESTABILIZING SLUDGE (TAILINGS) ABSTRACT OF THE DISCLOSURE       Wet-grinding of the oil-removed sludge suspensions is a better means of producing new reactive surfaces on the constituent minerals in the sludge than blender-grinding.         Prior treatment of the sludge by wet-grinding reduces the requirement of flocculant 573C by several orders of magnitude to achieve similar results of sludge flocculation as esti-mated by sedimentation using centrifugation.  This grinding process will work with other applicable flocculants.

Abstract: Abstract of the Disclosure In a race track microtron a linear accelerator increases the energy of injected electrons and deflecting magnetic fields cause the electrons to follow successively greater  orbits passing through the linear accelerator several times.  A method and apparatus for compensating for the effects of mis-alignment between the deflecting magnetic field systems in relation to each other and in relation to the linear accelerator in the race track microtron are disclosed.  The new technique involves generating on both sides of the linear accelerator a compensating magnetic field perpendicular to the common plane of the orbits, each compensating field intersecting all complete succes-sive orbits and having a field strength in the regions of the intersections which varies stepwise from intersection to intersection.  The magnitude and direction of the compensating magnetic fields may be varied while maintaining a linear relationship between the field strength at each intersection and the energy of properly accelerated electrons travelling in the respective inter-secting complete successive orbit.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention describes a valve in which the flow gate is operated by a piston in a hydraulic cylinder.        The piston is forced axially, against the resistance of a coiled spring, by means of hydraulic fluid pressure provided by a motor driven pump.  Electrical limit switches are provided on the movement of the piston.  A check valve is provided in the output of the pump so that once the gate has been moved to the desired position as set by the limit switch, the motor will be stopped and the piston will remain in its position.  To reset the piston to its original position, a solenoid by-pass valve is provided which is energized when the meter is energized, and when de-energized, provides a bypass between the cylinder and a sump, so that the pressure on the piston is released to atmospheric and the spring will force the piston back to its starting point.
