Abstract: ABSTRACT    This invention teaches a control to be used in smelting aluminum by the electrolysis breakdown of alumina (AL2O3) in a molten electrolyte heated to approximately 950-1000°C. The invention provides a sonic resonator and control that can accurately detect the resonant frequency of the resonator in the molten electrolyte.  The resonator preferably is made with tubular side wall 1/4 of the sonic wavelength, or is a quarter wave resonator.  A wave generator inputs a single having a range of frequencies that includes the resonant frequency, so that a peak resonant output at the resonant frequency can be detected on an oscilloscope or like detector.  This instantaneous resonant frequency is then checked against an accurate data base correlating the resonant frequencies of the resonator in the electrolyte at specific alumina concentrations normally experiences throughout the electrolysis cycle.  The electrolysis cycle can thus be controlled and recharged at any predetermined low alumina concentration greater than where the anode effect phase of the cycle normally might begin.

Abstract: ABSTRACT      The degree of cure of a traveling carbonaceous polymeric material  (on 48),  formed (at 34) from a plurality of chemical reactants (32) and subjected to a curing process (at 42 and 44) is determined by directing (with 86 and 88)  into the traveling material  radiations  including a  first  infrared  radiation  (A1) from  the  group  thereof  adapted  to  selectively  interact  with molecular   resonance   vibrations   at   frequencies   that   are characteristic of respective terminal functional groups of atoms involved in reactions that take place in the material during the curing process.   Also directed  into the material  is a second infrared radiation that is either of the kind (R) that does not exhibit   substantial   selective   interaction   with   molecular resonance vibrations in the material or of the kind (A2) that is adapted  to  selectively   interact  with  molecular  resonance vibrations at a frequency that  is characteristic of groups of atoms forming the backbones of the polymeric molecules  in the material.   Received  (at  102)  from the  traveling material  are radiations  (148)  that  have  interacted  with  the  material. Produced (at 116, 118 and 122) from the received radiations are first and second responses to the first and second radiations. Produced (at 122) is a third response that is a function of the mass of the polymeric material  interacting with the radiations. Produced (at 122) from the first, second and third responses is an output response (140, 82) that is correlated with the degree of cure effected by the curing process.

Abstract: Abstract:    A method and apparatus for the purification of water or other contaminated aqueous liquids.  The water is passed through a filter comprising a solid backwashable filter medium preferably having pores or slots of 125 microns or less made of biologically nondegradable and non-corrosive material, and having a specific, non-pathogenic aerobic activated sludge layer deposited thereon.  The aerobic sludge layer is prepared by aerating mixtures of raw water, diatomaceous earth and preferably an inert particulate biologically non-degradable filter material (such as cellulose powder), for a minimum period of 24 hours, and preferably at least five days.  The resulting mixtures containing a specific, non-pathogenic aerobic activated microbiological sludge is recirculated through the solid filter medium in a specific sequence until an activated sludge layer is deposited thereon to the desired thickness.  The resulting micronic microbiological filter is more efficient, less bulky, cleaner and easier to use than conventional sand and/or anthracite coal beds used as filters in conventional municipal water treatment plants and the like.  When water passed through the resulting filter is then passed through an activated carbon contacter bed at controlled flow rates, the microorganisms colonize the bed and complete the biological degradation of organics contained in the water.  Subsequent disinfection (e.g. with chlorine) makes the water potable.

Abstract: IMPROVED FIBER OPTIC ROTATION SENSOR               WITH EXTENDED DYNAMIC RANGE                         Abstract A fiber optic rotation sensor,  employing the Sagnac effect comprising all  fiber optic components positioned along a continuous,  uninterrupted strand of fiber optic material.  The rotation sensor includes a detection system utilizing a modulator or modulators for phase modulating at first and second harmonic frequencies light waves which counter-propagate through a loop formed in the fiber optic strand.    Each  modulator  is  operated  at  a  specific frequency  to  eliminate  amplitude  modulation  in  the detected optical output signal.    A phase sensitive detector generates a feedback error signal proportional to the magnitude of the first harmonic in the output optical signal.   The feedback error signal controls a modulator which controls the amplitude of the second harmonic driving  signal  for the second harmonic phase modulator such that the first harmonic component in the output signal from the rotation sensor is cancelled or held within a small range of amplitudes.

Abstract: ABSTRACT          A blind rivet of the type adapted to be inserted into the opening in a workpiece and having a flange at one end and adapted to be deformed by the head of a mandrel at the opposite end when the mandrel is pulled.  The blind rivet has an elongated rivet body carrying a flange at one end with a plurality of longi-tudinally extending weakened areas being provided on the body between the flange and the opposite end.  The weakened areas form slits which are spaced from the flange and the opposite end so that a continuous solid annular section is formed on the rivet body adjacent the flange and the opposite end.  Longitudinally extending solid portions are formed between the weakened areas that have abutting line contact throughout their longitudinally extent at the weakened areas.  These weakened areas are adapted to separate when the rivet body is deformed to form from the solid portions a plurality of outwardly extending petals that form an enlarged secondary head on the rivet.  The weakened areas only of the rivet body are adapted to be deformed when a mandrel, extending through the body is pulled so that minimal lateral forces would be exerted on an opening in a workpiece and the deformation of the rivet body would be localized.  When the rivet is deformed, the solid annular section adjacent the opposite end is adapted to retain the mandrel head to seal the rivet within the workpiece opening.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for recovering gold from refractory auri-ferous iron-containing concentrate includes feeding the con-centrate as an aqueous slurry to an acidic pretreatment step and treating the concentrate in the acidic pretreatment step with aqueous sulphuric acid solution to decompose carbonate and other acid consuming gangue compounds.  The treated slurry is oxidized in a pressure oxidation step at a temperature in the range of from about 135 to about 250°C under a pressurized oxidizing atmosphere while maintaining a free acid concentra-tion of from about 5 to about 40 g/L sulphuric acid to cause dissolution of iron, formation of sulphuric acid and oxidation of substantially all oxidizable sulphide compounds to sulphate form with less than about 20% of oxidized sulphur being pre-sent as elemental sulphur during the oxidation step.  Water is added to the oxidized slurry in a first repulping step to produce a repulped oxidized slurry with a pulp density in the range of from about 5 to about 15% solids by weight, the repulped oxidized slurry is subjected to a liquid-solids separa-tion step to produce an acid and iron containing solution and oxidized separated solids, a portion of the acid and iron containing solution is recycled to the acidic pretreatment step, and gold is recovered from the oxidized separated solids.

Abstract: ABSTRACT   IMPROVEMENTS RELATING TO SIGHTLINE STABILISING APPARATUS           In known sightline stabilising apparatus 10 (Fig, 1) a gyro-stabilised reflector 25 maintained in orientation in space about two axes 18 and 26 by gyro means in the mechanism 22. The  reflector  mechanism  is contained  in  housing  17  and  is pivotable about  elevation axis  18  in relation  thereto.    The housing  also  carries  a  sensor,  e.g.  a  tv  camera  providing signals to a remote  (non-stabilised)  image display device, and is  itself  rotatable  in  elevation  relative  to  a  platform  16 rotatable in azimuth.   The apparatus is normally carried by a vehicle  and  movements  thereof  cause  servo  responses  of  the mechanism 22 to stabilise the mirror and follow-up movements of the housing and pedestal 16 restore the mirror to the centre of its  limited  motion  in  the  housing.    However,  changes  in elevation angle of the reflector cause rotation of the remote image about the centre of its field of view and motion induced changes can rapidly lead to motion sickness in an observer of the  image.    The  improvement  of  the  invention  consists  of introducing  an  elevation  offset  between  the  mirror  and  the housing  so  that  the  sensor  is  offset  about  axis  18  and has essentially the same field of view from the mirror but the image formed  is  rotated  about  its  receptive  axis  20.    The  image rotation is equal to the elevation offset of the housing/sensor and   is   applied   as   a   demand   signal   into   the  housing elevation-restoring feedback loop.
