Abstract: ABSTRACT OF THE DISCLOSURE     A track working or transport vehicle comprises a frame and two undercarriages supporting the frame.    Springs are mounted between the side frames of the undercarriages and the vehicle frame, the springs having a stroke whose length is proportional to variable loads distributed to a respective undercarriage wheel from the vehicle frame. A displacement pickup is connected to each group of springs and arranged to measure the stroke thereof, the pickup generating an electrical output signal proportional to the measured stroke.  An arrangement for continuously monitoring and indicating the loads dis-tributed to the respective wheels includes a summation circuit having a first input receiving the output signals from the pickups, a second input receives fixed electrical signals proportional to the weight of non-yieldingly mounted parts of the undercarriages, and an output trans-mitting electrical output signals proportional to the wheel loads derived from the inputs. An indicator device receives each output signal from the summation circuit and correspondingly indicates the wheel loads.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates more particularly to a pressurized water nuclear reactor in which the heat exchange between the primary and secondary circuits takes place by means of steam generators.  A reserve tank is placed in the secondary circuit parallel to the steam generator and inside or outside the latter.  It is pressurized directly by the secondary fluid in the gaseous phase leaving the generator, so as to form a reserve increasing the inertia of the generator in the case of closing the steam and supply valves without significantly increasing it in the case of a fracture of the steam piping.

Abstract: X-RAY TUBE CURRENT CONTROL                 Abstract of the Disclosure The present invention relates generally to a closed loop feedback system for controlling the current output of an x-ray tube.  The system has circuitry for improving the transient response and stability of the x-ray tube current over a substantial nonlinear portion of the tube current production characteristic.  The system includes a reference generator for applying adjustable step function reference signals representing desired tube currents.  The system also includes means for instantaneous sensing of actual tube current.  An error detector compares the value of actual and reference tube current and produces an error signal as a function of their difference.  The system feedback loop includes amplification circuitry for controlling x-ray rube filament DC voltage to regulate tube current as a function of the error signal value.  The system also in-cludes compensation circuitry, between the reference generator and the amplification circuitry, to vary the loop gain of the feedback control system as a function of the reference magnitude.

Abstract: Abstract An engine starter drive adapted to engage an engine ring gear having a tooth driving clutch member which cooperate with a tooth driven clutch member. The driven clutch member further comprises a helical screw shaft with two circular grooves. A control nut threadably mounted on the screw shaft has a spring loaded detent which engages the circular grooves. The control nut is connected to the pinion gear by means of a retaining cup. Rotating the screw shaft causes the control nut to move along the screw shaft to traverse the pinion into mesh with the engine ring gears and crank the engine. When the engine fires, the acceleration of the pinion causes the control nut to move back on the screw shaft until the detent engages the first circular groove. After the engine starts and the pinion rotates to a predetermined speed, the detent withdraws from the first groove in the screw shaft and the control nut withdraws the pinion gear from engaging the engine ring gear. The detent then engages a second groove in the screw shaft to prevent undesired meshing of the pinion to the ring gear. If, during the engine cranking mode, the excessive torque is transmitted to the pinion gear by the ring gear, the driven clutches move away from the ring gear to compress a spring and resilient member to permit movement of the clutch members along solines coupling the driving clutch member to the power shaft and thereby absorb this torque by the resilient member. Indexing means also is provided to rotate the pinion gear to clear any abutment with the engine ring gear and causes the pinion gear to mesh with it.

The pump chamber is connected to the engine lubrication system and the turbo-charger bearings through suitable ducts and one-way valves, so that on ordinary operation of the engine the pump chamber is full of oil with the piston fully retracted.  On stopping the engine the piston moves under the spring bias discharging oil to the turbo-charger bearings until restrained by the catch arrangement. Subsequently on restarting the engine the piston is released so as to continue its movement under the spring bias again discharging oil to said bearings.

A positive or negative comma aberration imparted to the electron beam by the second field-control element is compensated for by a negative or positive comma aberration imparted to the electron beam by the first field-control element so that on leaving the latter, the electron beam sustains only an astigmatism, positive or negative, which is compensated for or corrected by an astigmatism, negative or positive, imparted to the electron beam passing through the deflection field.  Thus, distortions of beam spots at the edges of a screen can be substantially eliminated.
