Abstract: PRODUCTION OF DIALKYLALUMINUM HYDRIDES           Abstract of the Disclosure Dialkylaluminum hydrides are produced by subjecting a mixed aluminum alkyl having the formula R2AIR' to pyrolysis.  R is methyl, ethyl, n-alkyl or an alkyl group which has no hydrogen atoms on the carbon atom .beta. to the aluminum.  R' is an ?-or .beta. branched alkyl group having the formula   in which one R" is hydrogen and the other is alkyl and R'''is alkyl. The mixed aluminum alkyl R2AlR' can be obtained either by reaction of two aluminum alkyls:                2R3Al + R'3Al?       3R2AlR' or by reaction of a trialkylaluminum with a dialkyl-aluminum hydride: 2R3Al  +  R?AlH?     2R2AlR'  +  R2AlH, in which case one third of the desired hydride is synthesized.  The dialkyl aluminum hydrides are known to be suitable co-catalysts in the polymerization of olefin and di-olefin and as reducing agents for a variety of organic functional groups.

Abstract: ABSTRACT      A filter element for gas or liquid comprises a layer of glass, ceramic, metal, mineral wool or organic fibres containing, wholly within the layer, an apertured sheet, for example of steel or aluminium, the fibres being bound to one another throughout the layer and through the apertures, as well as to the sheet itself, by a synthetic resin such as silicon resin or polyurethane. The filter element is formed by mounting the apertured sheet a selected distance above the filter surface on which the fibres build up while a slurry containing the fibres is drained through the filter surface.  When the fibres have built up to a predetermined distance above the sheet, the fibres containing the sheet are removed and the assembly impregnated with a synthetic resin and cured.  Two or more grades of slurry mixture may be used in succession to produce a density grading through the thickness of the fibrous layer.  In the case of cylindrical elements, end caps are fitted and made fluid tight by a synthetic resin, a taper fit or a gasket.

Abstract: MODIFICATION TO THE BURNER IN A DIRECT COKING PROCESS                 ABSTRACT OF THE DISCLOSURE              Coked solids, produced by coking of tar sands, are contacted in a first zone with air and the minimum amount of supplemental fuel needed to burn all the coke.  Part of the hot clean mineral solids produced is then discarded; the bal-ance is moved into a second zone.  Here supplemental fuel is burned to increase the temperature of the solids.  The hot solids from the second zone are recycled to the coking stage.              Only part of the solids is heated with sup-plemental fuel, thereby reducing consumption of the latter.  In addition, the flue gas from the second zone is relatively clean and can be vented directly to the atmosphere in the flue gas from the first zone.

Abstract: Abstract of the Disclosure The transplanting apparatus includes a mobile frame supporting a rigid disc and a flexible disc mounted on a trans-verse shaft for rotation in unison about a horizontal axis as the frame traverses a strip of soil to transfer plants from a supply tape to a furrow.  Although the discs are spaced apart somewhat at their centers or hubs, at an upper location the flexible disc is flexed even a greater distance away from the rigid disc to provide a continuously open space for the succes-sive reception of the leaf ends of plants delivered from a supply tape.  At a lower location the flexible disc is sepa-rated from the rigid disc only enough to open the discs for the successive release of the plants into the furrow.  As the plants are transferred from the upper location to the lower location, the periphery of the flexible disc is pressed toward the rigid disc to assure retention of the plants during their downward travel.  The apparatus further includes a furrow opener and a furrow closer.

Abstract: Abstract of the Disclosure Steering control valves selectively pressurize and vent fluid-actuated clutches and brakes of a crawler tractor steering system.  Each control valve has an in-ternal spool assembly, coupled to a foot pedal by a cable, which modulates brake pressure as a function of pedal po-sition and which establishes a maximum brake fluid pressure thereby eliminating the need for additional system compo-nents for such purposes.  The control valves also provide a feedback fluid pressure, to resist pedal depression with a force proportional to the brake fluid pressures enabling an operator to sense the degree of braking which is present at different degrees of pedal depression.

Abstract: SYNC TRANSMISSION METHOD AND APPARATUS FOR HIGH FREQUENCY PULSED NEUTRON SPECTRAL ANALYSIS SYSTEMS     Abstract of the Disclosure.  A pulsed neutron generator in a well logging instrument is pulsed at a clock frequency of 20 KHz.  Inelastic scatter gamma rays are detected during a first time interval coinciding with the neutron source being on and capture gamma rays are measured during a second interval subse-quent to the end of each neutron burst.  Only a single detected pulse, assuming detection occurs, is transmitted during each of the two detection intervals.  Sync pulses are generated in the well  logging  instrument scaled down to a frequency of 200 Hz for transmission to the earth's  surface.  At the earth's surface, the scaled-down sync pulses are applied to a phase locked loop system for regenerating the sync pulses to the same frequency as that of the clock frequency used to pulse the neutron source and to open the detection gates in the borehole instrument.  The regenerated sync pulses are used in the surface instrumentation to route the pulses occurring  in the inelastic interval into  one section of a multi channel analyzer memory and the pulses occurring in the cap-ture interval in to another section of the multichannel analyzer.           The use of memory address decoders, subtractors and ratio cir-cuits  enable both a carbon/oxygen ratio and a silicon/calcium ratio to best struck substantially free of background radiation.
