Abstract: ABSTRACT          A set of photoelectric transducers, optically scan-ning a line transverse to the direction of movement of a character-bearing document to be electronically read, is periodically actuated to pick up light from a multiplicity of elemental areas of that document and to generate electrical analog voltages commensurate with the brightness of these area The analog voltages are serially read out from one or more shift registers as a pulse train or several parallel pulse trains each undergoing digitization and subsequent storage in respective cells of an associated memory.  A group of these cells contain, at a given instant, digital codes representative of the relative brightness of respective elemental areas otho-gonally arrayed in a square surface portion of the document divided into a middle zone and four diagonally adjoining peri-pheral zones, the middle zone being centered on the point cur-rently scanned.  The relative brightness of that scanned point is weighted by an adaptive field function, based on the relative brightness of the peripheral areas, to yield a responsive para-meter whose joint evaluation with the relative brightness of the scanned point yields a binary output signal.  A series of such output signals, derived from simultaneous readings of a corresponding number of adjoining transducers, is converted in-to a multibit word fed to a utilization circuit.

Abstract: ABSTRACT A low friction piston ring of split annular construction has a circumferentially extending recess formed at its upper outer portion to define an outer radial ledge which divides the outer axial surface of the ring into a recessed outer face and a reduced (as compared to the total outer axial surface) bearing surface.  The bearing surface preferably has a wear resistant coating thereon.  The outside diameter of the recessed outer face is less than the outside diameter of the bearing surface by an amount at least equal to the radial wear depth of the bearing surface.  A peripheral recess is also formed at the upper-inner portion of the ring to reduce or eliminate torsional twisting of the ring.  The ring provides a reduction in frictional resist tance between the ring and the cylinder wall, good sealing against gas blow-by and enhanced engine performance and exhaust emissions control.

Abstract: Title: Adjustable motor car mirror, and safety housing for mounting such a mirror.            Abstract of the disclosure:          An apparatus for adjusting a mirror or a similar flat planar element about two mutually perpendicular axes. The apparatus has a  housing enclosing a reversible motor an electro-magnetically operated clutch and two planetary transmission assemblies, one for each direction of movement. The clutch selectively couples the motor to one or the other of the two pinion sun wheels of the planetary transmission systems. The drive shaft of each planetary transmission assembly is provided with a dog, which engages a corresponding mirror adjustment unit. A mirror mounting plate is provided with recesses into which correspondingly shaped parts of the mirror adjustment units are introduced by snap forcing.          To suppress vibration of the mirror, the units are preferably arranged to act upon a tilting adjusting ring which in any position is in sealing contact with a raised edge of the bottom member of the housing. A safety housing for mounting the apparatus comprises a protective cap housing two substantially parallel partitions spaced apart so as to be capable of receiving the top part of a mounting column between them.          Clamping means force the partitions against the surface of the column. The cap will thus withstand light impact forces, but turn relative to the column when struck by a bicycle or other vehicle in traffic.

Abstract: RANDOM ACCESS RECORDING AND/OR PLAYBACK SYSTEM                 ABSTRACT OF THE DISCLOSURE     A random access system for recording and/or reproducing apparatus of the type used for recording information on and/or reproducing information from addressable portions of a record medium.  The random access system is capable of recording address signals on the medium adjacent corresponding addressable portions and of playing back address signals from the medium so as to access any addressable portion thereof to reproduce information therefrom.          The address signals are constituted by a variable number of address pulses plus a constant number of pulses.  The random access system includes a counter for counting pulses which are applied thereto so as to derive a count corresponding to an address.  A detector detects the constant number of pulses included in an address signal and supplies only the variable number of address pulses to the counter.  A selector is operable to select any one of predeter-mined addresses, and a comparator compares the count derived by the counter to the address selected by the selector to produce a coincidence signal when the count is equal to the selected address.  In a recording mode, an oscillator generates a substan-tially  continuous train of pulse signals which are supplied through the detector to the counter.  A record control circuit is operable to initiate an address recording operation for transmitting the train of pulses to the counter, and is responsive to the coincidence signal to terminate this address recording operation.  In a playback mode, the recorded address signals are supplied through the detector to the counter.  A sensing circuit is provided to sense the end of t? played back address signal and to actuate a control signal generator which is responsive to the coincidence signal for generating a -i-control signal which is adapted to initiate a predetermined operation of the recording and/or reproducing apparatus.                             -ii-

Abstract: METHOD FOR FASTENER TENSIONING     Abstract of the Disclosure A fastener tensioning system for use with torque produc-ing power tools, such as, nut runners or the like.  The system includes apparatus to rotate the fastener and deter-mine when the fastener has been driven to its yield point in tension, and, thereafter, the fastener is backed out a precise amount of rotation to establish a level of tension in the fastener below the yield point.  The method of this invention improves upon the conventional turn-of-the-nut method for fastener tensioning; in that, the precise fastener rotation is started from a relatively well-known and well-defined point as opposed to a arbitrary predetermined low level of torque.  In addition, the method assures by inspec-tion the proper condition of the bolt and thread prior to making the final tensioning step.

Abstract: ABSTRACT     A lens testing method and apparatus is disclosed to test the transfer function of a lens at a multiple number of points in the lens and to locate the best focal plane and format position of the lens within the specified focal range of the lens.  The lens is mounted in the lens tester between the object plane and the image plane.          The object plane has a multiple number of beam forming apertures which are illuminated to project individual light images through the lens to respective targets or target segments in the image plane.  The targets are a multiple number of apertures geometrically similar to the object aperture, having a fixed orientation to the object plane apertures.  The target and object planes are moved relative to one another such that the individual light images are moved across the apertures of their corresponding targets.  The light images passing through the target apertures are sensed to determine the transfer function of the lens at the respective points in the image plane.  The lens may be rotated 90° to test the meridional and the sagittal transfer function of the lens at each point.  In operating the lens tester, the lens is first moved to a suitable focal plane and the value of the transfer function at the desired points in the image are compared with predetermined minimum acceptable values of the transfer function.  If the value of the transfer function at any tested point in the lens falls below the minimum acceptable value, the lens is moved to another suitable focal plane and again tested.  Once all the points in the lens test above the minimum value of the transfer function for each respective point, the total of the transfer functions for each format position is determined by rotating the lens and testing again.          The one best format position and focal plane is then found by comparing the total value of the transfer function for each point in each suitable focal plane within the lens focal range with the total value of the previous best focal plane.  The lens may be rotated any number of steps in each focal plane to test as many format positions around the lens as desired to determine the best format position in the best focal plane.
