Abstract: A B S T R A C T   O F   T H E   D I S C L O S U R E    A rotary light tester for continuously inspecting empty cans discriminates between good cans and defective ones by judging the amount of transit light into the interior of the empty cans.  The light seal circular plate and the freely-reciprocative slide pusher which rotates with the continuous rotating star wheel are faced each other sandwiching each can receiving seat on the outer periphery of the star wheel at equal intervals in the circumferencial direction.          The nozzle opening of the tip of the slide pusher absorbs vacuously the bottom end of uncoated or unprinted bright can received in the can receiving seat one by one when the can enters into the empty can supply station just after the trimming.  Then, in the light detection station, the opening end of the can is inserted into the groove of the light seal circular plate having the black non-luster surface to further the reflection attenuation of outer entry light, the trap in the deepest portion thereof, and the conical introduction to make it easy to insert the opening end therein by advance pushing of the slide pusher.

Abstract: ABSTRACT       Radiant energy is caused to modulate in phase and frequency in a single mode optical fiber by means of a relatively movable, spatially perio-dic perturbation.  Specifically, an optical grating is mounted on the clad-ding at a control zone near the core of the fiber.  The control zone may be formed by removing a portion of the cladding to form a reduced thickness cladding portion.  The grating has its crests oriented generally normal to the optic axis of the optical fiber and the grating is caused to move rela-tive to the optic axis, for example by sliding along the optical fiber.  A shear mode piezoelectric transducer may be used to cause the necessary movement.

Abstract: ABSTRACT OF THE DISCLOSURE     A wheeled vehicle includes a vehicle frame having at least one wheel at one end of the frame and a hinged parallelogram frame mounted on the other end of the vehicle frame and having a pair of spaced wheels mounted on opposite sides thereof. The parallelogram frame will pivot laterally in first or second opposite lateral directions when the frame leans laterally away from a position of equilibrium in the first or second lateral direction. A sensing device is connected to the vehicle frame and a power source is connected to the sensing means and parallelogram frame whereby initial leaning movement of the parallelogram frame in one direction (caused by conditions of unequilibrium) will cause the sensing device and power source to pivot the parallelogram frame in the opposite direction thereby to laterally pivot the vehicle frame to a position of equilibrium. The sensing device may be a lever pivotally connected to the vehicle frame and the power source may include a pair of extensible and retractable cylinder units for connecting opposite ends of the sensor lever to opposite sides of the parallelogram frame.

Abstract: X-RAY SYSTEM TESTER                 Abstract of the Disclosure An X-ray system tester for measuring a set of electrical signals comprising anode voltage, cathode voltage, anode current, filament current and line voltage produced by an X-ray system during the operation of such system.  A selector is provided, which couples one of the electrical signals of the sets thereof produced or one of a plurality of processing control signals entered by an operator from a control panel, to a digitizing section, selectively in accordance with control signals provided to the selector by a computing section.  The digitizing section converts the selected signal whether produced by the X-ray system or entered from the control panel, into a train of pulses having a frequency proportional to the value of the selected signal.  The pulses in the pulse train are counted by a counter.          The number of counts being used by the computing section to determine the frequency, and hence, the value of the selected signal.  This computed value is stored in a computing memory section and the computing section which there selects a different one of the electrical signals for processing.  The computing section is also adapted to store a plurality of the sets of electrical signals produced during a corresponding sequence of operational intervals of the X-ray system and determines a measure of the deviation of any selected one of the stored electrical signals over the sequence of operating intervals.          The operator of the tester is able to recall from storage each one of the electrical signals produced during the sequential operational intervals to aid the operator in analyzing the operation of the X-ray system.

Abstract: ABSTRACT A twin-nozzle extrusion head includes basically three axially spaced but radially overlapping annular housing members, together establishing two nozzle gaps.  A first and a middle one of the two members are provided with annular feeder ducts for these nozzles   Each duct has on its exit side a baffle ring, one baffle ring being effective on its radially inner surface while the second baffle ring is effective on its radially outer surface of larger diameter.  These surfaces are non-circular in a predetermined manner to establish nonuniform gap widths related directly to the location of feed ducts for the annular channels.  Generally, the gaps are wider in locations out of proximity to the feed ducts.  The nozzle gaps are both frustoconical and of different steepness and terminate in a common plane.  The nozzles are particular-ly provided for disposing an adhesive on top of a steel pipe and a polyethylene coating and envelope on top of the adhesive.

Abstract: ABSTRACT      In controlledly cooling steel strip, the heat transfer rate needed for attaining the desired cool-ing rate is calculated from an equation including strip thickness, the cooling starting and finishing temperatures, and the desired cooling rate.  The flow rate of coolant is determined and set by using an equation expressing the predetermined relationship between the heat transfer rate and coolant flow rate.          The length of the coolant spraying region extending in the direction of strip travel is calculated from the running speed of the strip, the cooling starting and finishing temperatures, and the desired cooling rate.          The nozzles are set to turn on and off so that the coolant is sprayed from such a number of nozzles as correspond to the length of the spraying region thus calculated.  Based on these settings, the coolant flow rate is corrected by re-calculating the heat transfer rate when strip thickness varies in the course of controlled cooling.  Also, the on-off pattern of the nozzles is corrected by re-calculating the length of the coolant spraying region when the running speed of the strip varies.

Abstract: ABSTRACT OF THE DISCLOSURE INCHING SUPPLY TORQUE CONTROL    In a drive system for a grinding mill the load torque plus frictional torque may increase considerably as a loaded mill is inched from its rest position and will suddenly decrease when the load tumbles or cascades.  The applied torque or driving torque must increase at a corresponding rate and should also decrease when the load cascades.  If the applied torque exceeds the load torque plus frictional torque, a destructive hammering will occur in the gear train and this will be generally proportional to the excess of applied torque for a synchronous motor drive.  The drive system has a DC source which is commutated by a commutating device to provide a low frequency stepped alternating voltage to the synchronous motors of the drive system for inching.  The output of the DC source has an alternating component which varies as the difference between the applied torque and the load torque plus frictional torque.  The alternating component is detected and a control signal is derived from the alternating component and used to regulate the DC source to reduce the alternating component and thereby cause the applied torque to approach the sum of load plus friction torques.
