Abstract: ABSTRACT OF THE DISCLOSURE        A process for making sintered metal articles of high strength in which a flowable mass of metallic particles and a foundry sand synthetic resin binder is initially formed into a green compact having shape stability in a forming machine of the type used in the fabrication of sand cores in the metal casting field.  The green compact is then subjected to sinter-ing and the sintered body may be pressed, forged or mechanically shaped in other ways.  The core blowing or core sand slinging machine used to produce the green metal compact is surprisingly effective in producing a dense, reproducible structure in light of the fact that sand cores for casting purposes are inten-tionally made frangible to enable them to be removed effectively from the casting.

Abstract: ABSTRACT      A method for the in situ processing of oil shale ore includes  the  establishment  of  underground  stopes  by removing  from  each  a  portion  of  the  oil  shale  ore therein,  rubblizing  the  remaining  ore  in  each  stope, extracting the rubblized ore and crushing it to obtain a desired  particle  size  for  subsequent  processing,  and restoring the sized oil shale particles to the stope by backfilling the stope as the rubble is extracted.   The stope  is maintained  substantially  filled with  ore to provide lateral support to the sidewalls and reduce the likelihood of caving  in the stope.   The oil shale is retorted by  injection of  hot gas  into the stope,  and residual carbon is recovered from the retorted ore as producer fuel gas.   The sensible heat in the ore may thereafter be recovered for use in retorting oil shale ore in an adjacent stope.   Nahcolite may be recovered from a nahcolite-bearing oil shale ore by crushing the rubblized  ore  to  obtain  a  first  fraction  of  smaller nahcolite particles and a second fraction of crushed oil shale particles having the size desired for retorting, and separating the smaller nahcolite particles from the larger oil shale particles prior to backfilling of the stope.  If the shale is dawsonitic, soda ash and alumina may be recovered from the spent shale by leaching the stopes after retorting.   A method of retorting is also disclosed in which three retorts are operated in series, the first retort comprising a gas heating retort,  the second a carbon recovery retort, and the third an active kerogen-recovery retort.

Abstract: ABSTRACT:     The indication of temperature discontinuities in a scene may, when taken with other known facts about the scene, indicate the boundaries of objects, for example the level of the contents of a storage silo.  The scene is imaged in thermal radiation upon a pair of adjacent pyro-electric radiation detectors.  The scene radiation is chopped and the difference in detector outputs displayed to the observer while the field of view of the detectors, aligned with a visual aiming sight, is traversed across the object.  The location and sign of a temperature dis-continuity in the visual scene may for example enable the observer to measure the silo contents.

The ink drop deflector includes in one form a pair of differently sized electrodes which are positioned adjacent the trajectory near the orifice to create a non-uniform electric field with a sufficient poten-tial gradient to deflect neutral ink drops with a relative low switching voltage.  In another form of the invention, a plurality of electrodes are so placed adjacent an ink drop trajectory so as to cooperatively produce an electrostatic ink drop deflection force in a desired direction while cancelling force components in other directions.  Several embodiments are illustrated including an array of ink drop deflectors.

Abstract: Abstract of the Disclosure An arc suppression device (40) for protect-ing the load carrying contacts (30, 31, 32) of a power contactor (20) includes gate controlled semi-conductor devices (TR1, TR2, TR3) connected in parallel with the contacts.  A signal from a control circuit (45) causes gating current to be applied to the semiconductor devices nearly simultaneously with the application of current to and removal of current from the solenoid (25) of the power contactor.  A source of gating current of sufficient magnitude and character is provided to gate each thyristor into the conducting state substantially immediately.  The source of gating current may be either direct current or high frequency alternating current.  Circuit means (90, 95, 101) responds to the control signals to provide the gating current for a limited period of time prior to, during and following the closing of the contacts.  Gating current is not continued after the contacts have closed to protect the semiconduc-tors from possible damage.  Additional circuit means (110, 115, 101) responds to the removal of the con-trol signal to provide gating current for a limited period of time prior to, during and following the opening of the contacts.  An isolation relay (120) may be provided to prevent leakage current from flowing through the semiconductor devices to the load while the power contacts are open.

Abstract: ABSTRACT      Sorting and inspection apparatus and methods which may be used for the identification and separation of articles of different characteristics, or the inspection of articles of similar characteristics to reject those of below  minimum standards.  A typical system will include a transport system for individually transporting the articles past a television camera so that the camera may view the distinctive portions of the articles to be sorted or the area of the articles to be inspected.  The output of the television camera is digitized based upon the number of transitions of light to dark (or dark to light)  in the scan lines.   A correlator then performs a specialized correlation between the digitized image and various previously digitized images representing the different items being sorted or inspected, to determine which of the previously stored images best correlates with the digitized image from the television camera.  A second correlation may be done using a different correlation technique, if desired, to make the final decision based upon the extent of differences between the prestored digitized images and the digitized image from the television camera.   The prestored digitized images may be initially created or stored by placing an article with the characteristic to be recognized in front of the television camera and then recording the digitized image.  Many refinements and alternate embodiments are disclosed.

Abstract: ABSTRACT          A light pick-up device for transparency and/or opaque scanning in either a drum or flat bed scanning device consists of a hollow body, which exhibits a light entry opening for the modulated light coming from the master.  The inside surface of the hollow body, which is designed as a light pick-up surface for the opto-electronic conversion of the scanning light into an image signal, consists of a multitude of sub-surfaces, whose surface normals are oriented in the direction of the incoming scanning light.     The sub-surfaces are the light surfaces of either opto-electronic transducers or are the end faces of optical fibers whose other end faces are coupled to an opto-electronic transducer.  Because the disruptive influence of scratches and shadow edges in the master is suppressed, a high efficiency and a good uniformity of the scanning are achieved with the light pick-up device.
