Abstract: ABSTRACT OF THE DISCLOSURE    A catalyst comprising nickel sulfide and tungsten sulfide supported on a titania-silica mixture oxide is used for selective hydrogenation of a heavy hydrocarbon oil containing polycyclic aromatic hydrocarbons to produce a liquid product rich in cycloparaffins.  By thermally cracking the resultant liquid product, it is possible to produce light olefins and monocyclic aromatic hydrocarbons in a far higher yield than by the direct thermal cracking of the same heavy hydrocarbon oil.

Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is a railway car support structure having a longitudinally extending chassis with a pair of end axle and wheel assemblies supporting the chassis and an intermediate axle and wheel assembly.  Each end axle and wheel assembly is connected to the chassis for turning movement relative to the chassis for guided engagement with associated tracks.  The chassis and the intermediate axle and wheel assembly are mounted so as to provide slidingly guided transverse movement of the intermediate axle and wheel assembly relative to the chassis, whereby positive engagement of the intermediate axle and wheel assembly with associated tracks is assured.  A steering beam is directly connected to the intermediate axle and wheel assembly and extends to and is directly articulatingly connected with respective end axle and wheel assemblies.  The steering beam is operative in a substantially constant horizontal plane attendant to lateral movement of the intermediate axle and wheel assembly to effect pivoting of the end axle and wheel assemblies for steering.

Abstract: Abstract of the Disclosure In Czochralski crystal growing operations, particularly those involving growth of silicon crystals, projecting formations of silicon monoxide sometimes form on the surface of the melt-containing crucible just above the initial level of the melt.  These formations are avoided by perturbing chemical formation conditions at the region of probable formation.  Such perturbations may be provided by a tube through which either a positive pressure of a gas, such as argon, is directed toward the region of probable formation or through which a negative pressure may be applied to perturb the formation conditions.

Abstract: ABSTRACT OF THE DISCLOSURE A solid state television camera which is free from the noise caused by defects in semiconductor substrate is disclosed. Solid state image sensors derive a plurality of picked up signals. Detectors detect the noise in the picked up signals when the image sensors pick up an image of a reference object, and these detected signals are temporarily stored in a memory which memorizes the noise signals derived by the detectors. Sampling hold circuits which are supplied with the picked up signals are controlled by the memorized signals corresponding to the noise to remove the noise from the picked up signals.

Abstract: METHOD OF RECORDING IMAGES ON A RADIATION            SENSITIVE MATERIAL            Abstract of the Disclosure A method of recording images on a radiation sensi-material comprising forming a layer of a radiation sensitive material comprised of a heterogeneous mixture of substances. At least one of the substances of the heterogeneous mixture serves as a solvent capable of con-verting its states of aggregation in the mixture under the action of the intrinsic or reflected radiation ob-tainable from the object being recorded. Another substance of the heterogeneous mixture, in the form of particles, is capable-of interacting with a force field. The layer is introduced in a force field and an image of the object being recorded is projected on that layer. The produced image is fixed by converting the state of aggregation of the heterogeneous mixture. The proposed method makes it possible to record images in any spectral range of the intrinsic and reflected radiation of the object. Images of any objects can be recorded on that layer containing no silver halides.

Abstract: L. EA DuBois ek al. Case 1-1 DIODE CHIP WITH IDENTIFYING SHAPE     Abstract of the Disclosure In the production of varistors, diode chips are cut from a p-n sheet-diffused semiconductor wafer.  Instead of having conventional rectangular shapes, the chips have a rhomboidal shape.  This makes the shape of the chips asymmetric in that one surfàce of each chip becomes a distinguishable mirror image of its other surface.  The direction of the p-n junction in the wafer is oriented with respect to the shape of the chips to be cut to place the same conductivity type region adjacent to the same rhomboidal shape of the surface.  As a result, the polarity of the chips, or the direction in which the p-n junctions are oriented within the chips, becomes identifiable by the shape of the chips.  This substantially aids in sorting, inspecting, assembling and other  handling operations performed on the chip. the chips can, for instance, be inspected visually to determine whether the p-type or the n-type doped portion of the chips are facinq away from a supporting surface.  Moreover, mechanical means sort the chips into two groups each consisting of chips of the same polarity or orientation of their p-n junctions with respect to a common support plane.  Once sorted, the chips are loaded with such known orientation of their p-n junctions into a mass assembly fixture where they become solder-bonded to electrical leads to form the varistors.     -i-
