Title: Method of preparing aluminate solution from sinter  containing alkaline aluminates
Inventor: ARONZON VITALY L
IPC: C01F7/04
Filed: 1983-02-01
Granted: 1987-05-26
Abstract: ABSTRACT OF THE DISCLOSURE           A method of preparing an aluminate solution from sinter containing alkaline aluminates is based on the diges-tion of the sinter by an alumina production recycled liquor and by a weak alkaline solution, whereby a suspension is obtained whose liquid phase is aluminate solution.  The method also incorporates a counter-flow multi-step washing of suspension solid phase, washing waters being obtained at each washing step, weak alkaline solution being obtained at the first step, and washed mud, at the last step.  Fed to the digestion process, the sinter is taken in an amount directly proportional to the total flow rate of the recycled liquor and of the weak alkaline solution, the recycled liquor being taken in an amount directly proportional to the flow rate of the weak alkaline solution, the weak alkaline solution being taken in an amount directly proportional to the caustic soda content in the washed mud.  The total volume of the suspension solid phase and of the washing water is kept constant either by varying the quantity of the washing water fed to a given rinsing step, or, at the last step, by varying the quantity of the water fed for washing. Caustic soda concentration in the aluminate solution, alka-line module of the aluminate solution, and caustic soda con-tent in the washed mud are kept constant within the limits specified by the requirements of the manufacturing process. Compared to the known methods, the proposed method has the advantages which follows: an increased extraction of useful components into solution, a reduction losses of aluminium oxide and of alkaline with the washed mud, stabilized com-position of the aluminate solution obtained, as well as a rise in the efficiency of filtering process, and a reduc-tion in the viscosity of suspension obtained.

Abstract: ABSTRACT       A termination device for absorbing RF energy waves in the termination chamber of a traveling wave tube.  The termination device is formed by modifying two wedge shaped termination devices of the prior art.          Specifically, two prior art single wedge termination devices are sliced in half to produce two wedges each one half the thickness of the single wedge device.          The two halves are positioned with their newly formed surface, formed by the slicing, in opposed facing contact.  The new double wedge thus has the same thickness as the prior single wedge and is readily accommodated within the termination chamber.  The double wedge termination device greatly reduces small signal gain variations across the operating frequency band of the traveling wave tube.

Abstract: DIFFERENTIAL MAGNETORESISTIVE SENSOR FOR            VERTICAL RECORDING     Abstract of The Disclosure An MR sensor is disclsoed in which a pair of thin film magnetoresistive strips are connected electrically in parallel between two terminals.  Strips are spaced apart a distance which is small relative to the density of the stored data to be sensed.  The strips are mutually-biased in opposite directions to corresponding points in the linear region of their respective curves by current from a constant source attached to one terminal.  Since the resistance of each strip is equal, the current divides equally between the strips.  The sensor is positioned adjacent the magnetic surface containing stored data.  Vertical components of the magnetic field (preferably vertically recorded data) influence the resistance of the strips differentially.          When the sensor encounters a vertical flux transition, the output voltage varies to produce a unimodal type pulse.

Abstract: ABSTRACT A method and apparatus for the crystallization of solids from liquids includes a vessel having an elongate vertical spray chamber which overlies and is in flow communication with a collection basin for collecting slurry from the spray chamber. The collection basin has a cross-section larger than the cross-section of the spray chamber and preferably includes a side wall which extends upwardly beyond the lower end of the spray chamber to define an opening between the basin and the spray chamber which communicates with the atmosphere. A blower is located in the top of the spray chamber to draw air at substantially ambient atmospheric conditions through the opening between upper end of the basin and lower end of the spray chamber and upwardly through the chamber. The slurry solution which is to be concentrated and crystallized is sprayed into the vessel and directly contacts the air flowing through the vessel thereby re-sulting in evaporation and concentration of the sprayed slurry and the crystallization of solids therefrom. The slurry collected in the collection basin is recirculated and returned as a spray at the upper end of the chamber. If desired, the recirculated slurry may be heated prior to being returned as a spray at the upper end of the chamber. The method and apparatus may utilize waste heat in its operation and may also be employed to con-dense the otherwise wasted vapor from a series of vacuum evaporators and further concentrate the product.

Abstract: Improvement in Apparatus for Filtration (Anthony N. Sharpe, PO Box 1224, Almonte, Ont. KOA lAO, Canada) ABSTRACT When filtering fluids the filter means and the receptacles for fluid before and after filtration are commonly individual and must be assembled together in order to perform filtration.  The individual items are also commonly rigid, bulky, and require cleaning for re-use.  My invention provides a disposable filtration apparatus constructed from a filter means and flexible impermeable film, joined together in such manner as to form fluid receptacles connected internally by the filter.  Being preformed, the apparatus requires no assembly by the user.  Moreover, by lying flat it occupies negligible space before use and can be dispensed from a roll or stack, yet being flexible it dilates or contracts to accept the sample to be filtered and accomodates the movement of fluid during filtration.  One embodiment of the invention employs a filter means capable of retaining undesirable microorganisms and a drinking tube which allows the user to enjoy microbiologically pure water.  Chemical or biochemical test reagents may be incorporated into the apparatus so that simple tests requiring filtration and addition of test reagents can be performed automatically.     SPECIFICATION The invention is concerned with apparatus for filtration of fluids and of carrying out chemical or biochemical analyses requiring prior filtration of fluids.    In one of the commonest laboratory techniques a suspension of solid particles in liquid is separated out by filtration. In its simplest form the filtration is brought about by folding a disk of filter paper into a cone, fitting the cone into a rigid conical filter funnel and inserting this in a flask which is the receiver for the filtrate.  More complex apparatus may require elaborately constructed filter means, filter supports, vacuum or pressure pumps and valves.  After filtration is complete the apparatus is normally readied for re-use by disassembling it and washing or sterilizing

If the thermopile is used to generate electricity, the heated junctions will be much larger in cross-section than the normal cross-sectional area of the conductor elements and they will also be much larger in cross-section than the junctions in the cooler zone. If the thermopile is to be used as a cooling device rather than an electric generating device and electricity is applied to the thermopile, then the cold junctions will be much larger in cross-section than the warm junctions and the cold junction cross-sectional area will also be much larger than the cross-sectional area of conductor elements of the thermopile.  In a variation of the thermopile the conductor elements are made of materials which are dissimilar to the larger cross-sectional area junctions and to each other.  Also, the junc-tions having a smaller cross-sectional area may be made of materials dissimilar to the materials from which the conductor elements axe made.  A method of making such thermopiles utilizing thin-film technology is also shown.
