Abstract: Abstract of the Disclosure An image-forming element is disclosed comprised of a support and a coating thereon containing a cobalt(III)-complex and a compound containing a conjugated .pi. bonding system capable of forming at least a bidentate  chelate with cobalt(III).  The coating is predominantly free of anions which will form conjugate acids by deprotonation of a cobalt(II)complex containing the chelating compound.  In one preferred form the image-forming element is radiation-sensitive.  In this form the image-forming element can contain a photoactivator capable of initiating reduction of the cobalt(III)complex.  An imaging process is disclosed in which the coating is exposed to actinic radiation to produce an image.  Images can be recorded directly within the image-forming coating or in a separate image-recording element or layer by use of the residual cobalt(III)complex or by use of one or more of the reaction products produced  by exposure.  By using the ammonia liberated from ammine ligand containing cobalt(III)complexes on exposure in combination with imagewise and uniform exposures, positive or negative images can be formed in diazo image-recording layers or elements associated with the image-forming coating.

Abstract: ABSTRACT OF THE DISCLOSURE            An improved rotary vacuum filter for producing filtration blanks or what may be termed pellets from slurries, especially for example, iron ore slurries.  Known rotary filters utilize spiked deflecting rollers to remove iron ore agglomerates from interstices in a lattice-like belt.  The use of a spiked deflecting roller necessitates the use of a metal belt which is difficult to produce since the belt must be sufficiently flexible to both pass around the deflecting roller and lie sealingly against the surface of a vacuum drum without permitting entry of outside air.  This problem is over-come by the present invention which provides a vacuum filter whereby dehydrated iron ore agglomerates are easily released undamaged from the belt without impairing the suction effect produced by the drum.  The rotary vacuum filter according to the present invention comprises a filter drum adapted to rotate about a horizontal axis while partly immersed in a filter trough filled with slurry, the filter drum is provided with a filter lining and a suction area, a forming belt, divided like a lattice, lies against the filter lining over the entire suction area of the drum and is adapted to rotate therewith, the forming belt extends from the drum over a deflecting roller arranged at a distance from the drum, the deflecting roller having a diameter smaller than a diameter of the drum, the belt adapted to be lifted off the said drum at an end of the suction area by means of the deflecting roller and being returned thereto before being immersed in the filter trough, the lattice forming belt having walls made of resiliently flexible material, interstices in the lattice for holding filtration blanks, said interstices being tapered conically towards a surface of the belt lying against the filter drum whereby filtration blanks are removed from the interstices by squeezing action as the belt passes around the deflecting roller.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for heat treating pulverous raw material such as cement raw meal prior to subjecting it to further heat treatment such as sintering.  By directing the raw material to a multi-stage preheater having a final stage which comprises at least two substantially equivalent sub-stages and directing hot gases to the preheater in a manner to contact the raw material, an effective heat exchange between the raw material and the hot gases is achieved.  The raw material is directed from the penultimate preheater stage so as to be entrained in the hot gases prior to directing the hot gases to the sub-stages of the final stage of the preheater and the hot gases and entrained raw material are divided into substantially equal divisional flows with each divisional flow being associated with a sub-stage of the final stage.  Each divisional flow is directed to an associated sub-stage of the preheater final stage and each flow is deprived of the raw material therein in a manner to produce individual, separate and substantially equal continuous sub-flows of raw material.  An apparatus is disclosed for practi-cing the inventive method and a rotary kiln plant is disclosed in which the inventive apparatus is incorporated to produce cement clinker by practicing the method of the invention accord-ing to the preferred embodiment.

Abstract: QUANTUM INTERFERENCE JOSEPHSON LOGIC DEVICES          Abstract of the Disclosure A quantum interference Josephson junction logic device is disclosed which comprises three or more junctions connected in parallel which are capable of carrying Josephson current and includes means integral with at least one of the junctions for carrying a larger maximum Josephson current than the remaining junctions.  The spacing between the lobes of the thres-hold curve is increased over that of a two junction interferometer result-ing in an increased operating region in which logic circuits switch to the voltage state.  Good current gain with large lobe separation may be obtained if the two outer junctions having a zero field threshold current, I0, are connected via an inductance, L, to the center junction with a maximum Josephson current, 210.  Apart from the gain enhancement due to increased current in at least one of the junctions and that due to the combination of increased current in at least one of the junctions and the symmetrical dual feed, increased gain and operating range can be achieved using the symmetrical dual feed in combination with interferometer arrangements where the maximum Josephson current in all the junctions thereof is the same.
