Abstract: ABSTRACT       A compact, portable bar code scanner, employing as a light source a light-emitting diode, consumes extremely low  input power.   The scanner,  which detects the reflectances from bars and spaces of the bar code symbol, uses optical beam-shaping methods to attain a large depth-of-focus for a non-laser system.          A shaped illuminating light beam is caused to blink when the symbol is outside the depth-of-focus range and a signature imposed upon the light beam enables the  scanner  to  substantially  reject  light interference.  A scanning version employs an optical assembly mounted upon a bimorph leaf spring that is caused  to vibrate  at its natural  mechanical resonance.  The scanner operates with bar code symbols  responsive  to  red  light and  is  of sufficiently low weight to be easily hand-held.

Abstract: ABSTRACT An  electronic  ignition  system  is  disclosed  for controlling as a function of a selected engine parameter the ignition instant of an internal combustion engine having at least one cylinder and a piston disposed therein and coupled to a rotatable crankshaft of the engine to define a first reference  position with  respect  to  the  crankshaft.   The ignition instant occurs upon the termination of an arc of crankshaft  rotation  at  a  second  variable  position  with respect  to  the  first  reference  position.   The  arc  of crankshaft  rotation  is  initiated  at  a  third  reference position  fixedly  disposed  before  said  first  reference position  considering  the  rotational  direction  of  the crankshaft.   More  specifically,  the  electronic  ignition system comprises a  first  sensor responsive to crankshaft rotation for providing a first train of signals of a first frequency,  each  first  signal  occurring  in time when the crankshaft rotates past its third reference position, and a second  sensor  responsive  to  crankshaft  rotation  for providing a second train of signals of a second frequency greater than  the  first frequency and proportional to the speed of angular rotation of the crankshaft.  A counter is coupled to receive the first and second trains of signals and actuated upon the occurrence of each signal of the first train for integrating the second train of signals to obtain an  indication  of  the  present  crankshaft position with respect  to  said  first  variable  position.   The  present crankshaft position  is  used  to  determine  the  ignition instant.

Abstract: APPARATUS FOR COOLING A STRIP           PRIOR TO A MINISPANGLE OPERATION                 Abstract of the Disclosure A steel strip (10) is conveyed through a galvanizing bath (20) of molten zinc, a zinc coating weight control device (12), and a minispangle box assembly (16).  The steel strip emerges from the zinc coating weight control device (12) with a non-uniform temperature distribution across its width in which it is warmer in the center and cooler at its edges.  A differ-ential, pre-cooler assembly (18) cools the steel strip selec-tively and non-uniformly across its width in a manner which is complimentary to the temperature distribution thereacross.  In this manner, the steel strip exits the pre-cooler assembly (18) and enters the minispangle box assembly (16) with a more uni-form temperature distribution.  This results in a more uniform minispangle appearance on the strip (10) as it exits the mini-spangle box assembly (16).  The pre-cooler assembly includes a plurality of nozzle pairs (32a, 32b; 34a, 34b; 36a, 36b; 38a, 38b).  The nozzles of each nozzle pair are disposed in a facing relationship on opposite sides of a work path, and include a pair of conduits (60a, 60b) which define an array of apertures (62a, 62b) therealong.  A damper (66a, 66b) is provided to se-lectively cover the apertures in each array.  Each damper has a leading edge (72a, 72b) which is somewhat U-shaped so that as the damper is adjusted relative to the associated conduit, the apertures of the array are progressively covered from the outer edges toward the center, or progressively uncovered from the center toward the edges.

Abstract: "TORQUE SENSOR"                        ABSTRACT OF THE DISCLOSURE                The sensor comprises a pair of shafts mounted end to end for rotation within a stationary housing.  The adjacent ends of the shafts are spaced apart by a thrust bearing so that axial force can be trans-mitted from the first shaft, connected to motor means, to the second shaft, connected to load means, but the first shaft can still oscillate relative to the second shaft.  A sleeve encases the adjacent ends of the shafts.  Balls, positioned in grooves formed in the sleeve and second shaft, lock the two together for rotational movement but enable the sleeve to slide longitudinally.  Helical slots are cut in the sleeve portion encasing the first shaft.  The first shaft carries cam followers which engage the slots.  When torque is applied to the first shaft, the cam followers force the sleeve to move longitudinally in proportion to the torque.  The sleeve biases a piston which pressurizes hydraulic fluid to actuate a Bourbon tube and provide a read-out of the torque measurement. The torque is transmitted from the first shaft through the balls to the second shaft and the shafts and sleeve rotate as a unit.
