Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a process for the electrolytic recovery of gallium from an aluminate liquor produced by the production of crystalline alumina and containing sodium as well as gallium, the process comprising the steps of, applying a mercury layer to a surface of a carrier electrode of a metal more electronegative than mercury until mercury coats said surface to form a mercury cathode, electrolyzing said aluminate liquor at a temperature of less than 50°C with said mercury cathode to initially deposit sodium upon said mercury cathode and then depositing gallium thereon, and solubilizing the gallium from said mercury cathode by treating the same with a gallium-solubilizing medium thereby regenerating said mercury cathode for reuse of the same in step (a) for further acceptance of said recoverable metal.

Abstract: ABSTRACT OF THE DISCLOSURE   A surface acoustic wave filter having a,piezo-electric substrate with a major surface, input and output transducers which are formed on the major surface. Finger electrodes of one of the transducers are made as step type ones to divide the surface wave propagation path into a plurality of surface wave propagation channels. The phase difference of channels and the length of the steps of the finger electrodes are determined to minimize the multiple re-flection echo between the input and output transducers. Some ripples in the pass band are improved.

Abstract: ABSTRACT OF THE DISCLOSURE           Sodium bisulfite, for use in the acid digestion of wood to produce pulp is obtained for the process by passing calcium bisulfite through a strong cation exchange resin in the sodium form and regenerating the exchanger with sodium chloride.   The calcium bisulfite for the process can be obtained in a known manner, for instance, in an acid tower of the sulfite pulp industry or by passing sulfur dioxide through milk of lime.   The process avoids environmental pollution caused by the usual discharge into streams of waste calcium salts from the older sulfiting processes and by the release into the atmosphere of sulfur dioxide containing combustion gases.

Abstract: TITLE          APPARATUS FOR DETERMINING THE POSITION OF A SURFACE                       INVENTORS                  ROY A. NODWELL              STEVEN L. F. RICHARDS             ABSTRACT OF THE DISCLOSURE     This invention is directed to an electro-optical apparatus for determining the position of an opaque surface without contact with the surface.  It includes a light beam system which projects a well defined beam having a rectan-gular cross-section, obliquely onto the surface such that any movement of the surface in the perpendicular direction will result in a displacement of the illuminated area on the surface, and a detector which converts this displacement into a proportional light intensity.  The detector has a field stop with an aperture of specific shape onto which the illuminated area is imaged such that only a portion of the image will pass through the aperture depending on the displacement of the illuminated area.  A photosensitive device is used to measure the light intensity passing through the aperture.          Embodiments of apparatus for normalizing the output for greater precision are described as well as a system for measuring the thickness of an object by determining the position of two opposite surfaces of the object.

Abstract: GEAR SYSTEM     ABSTRACT OF THE DISCLOSURE A reduction gear system includes a pair of sets of meshing pinions and internal gears having a substantially larger diameter than the pinions, a shaft connecting the internal gear of the first set to the pinion of the second set, a second shaft supporting the pinion of the first set, a third shaft supporting the internal gear of the second set, the axes of said second and third shafts being in alignment and parallel to but spaced from the axis of the first shaft. Additional parts of sets may be connected to the first pair. When used between the motor and drill bit of an oil well drill the shafts, pinions and gears are supported in an inner housing within an outer housing with a fluid mud passageway therebetween. The inner housing includes a grease chamber and the pressure of the grease is kept greater than the mud pressure by means of a piston surrounding the shaft at the top of the housing. The top of the top piston and bottom of the lower piston are exposed to the fluid mud and springs provide additional force urging the pistons toward one another.

Abstract: Method & Apparatus For Web Treatment Abstract of the Disclosure A running textile web that has been subjected to soaking by a liquid such as a scouring solvent is carried between a suction box located adjacent one face of the web and a source of pressurized and relatively dry heated gas adjacent the other face thereof and opposite the suction box.  The heated gas passes through the web and is drawn into the suction box, en-hancing the amount of liquid removed at this stage and present-ing the web into a drying stage with less entrained liquid than if the web were subject to the action of the suction box only.  The amount of mechanical mist is kept to a minimum within a closed scouring range by means of a closed loop between the suction box and a return conduit provided with a trap contain-ing a batt of metallic wool.  The liquid discharge from nozzles employed to uncurl the edges of the web is directed against shields also containing a batt of metallic wool to reduce bounc-ing, noise and mist generation.

Abstract: ABSTRACT OF THE DISCLOSURE           A particulate composition which can be used as a fertilizer or feed or food additive for animals or humans is provided which comprises microencapsulated lipids in albumin.  A process is also provided for making such com-position which includes forming a dispersion or emulsion of globules of nutrient lipid within an aqueous albumin containing medium and thereafter forming a gel.  The result-ing gel can then be dried to form the particulate nutrient composition.  This process is especially applicable in the use of animal blood as the source of albumin and provides for significant reduction of odors commonly associated with the drying of blood and thus represents a pollution control measure.  The process can make a particulate nutrient feed additive or supplement which when fed to ruminant animals will preclude the bio-degradation of the majority of the nutrients in the rumen compartment of the stomach and thus provide for the manipulation of the site and form of assimulation of the nutrients by the ruminant is also provided.

Abstract: DIGITAL-ANALOG CONVERTER                ABSTRACT OF THE DISCLOSURE          This digital-analog converter receives a digital number and applies it to a counter capable of handling an n-bit binary number.  When the counter counts to its full capacity, e.g. 1111 for a 4-bit counter a writing signal generated in a control section causes the compliment of the applied number to be written into the counter.  The counter is then able to start counting from this complement number to the full (1111) number again.  The control section then complements the written-in number back to the original number and counts up to the full number yet again.          Thus, if the original binary number is 0011  and the reverse number, the counter counts 1100 and 1011 repetitively.  At each count reversal, a flip-flop reverses, and a pulse corre-sponding in length to the original number is produced within each full count interval and that pulse is filtered by a low-pass filter to produce an analog signal corresponding to the original digital one.

An inlet passage is provid-ed for each closed-loop passageway to conduct to the latter, as the rotary piston rotates, pressurized cooling fluid from a source thereof.  An outlet passage is provided for each close-loop passageway to conduct heated cooling fluid from the latter to an area adjacent the hub portion.

Said first layer of weft threads crosses said warp threads on said outer face of the fabric closest to the material to be formed, in at least 80% of all cross points, or according to the shaft (harness) number used in between 80% and 90% of all cross points, where-by the wefts on the fabric face turned towards the material to be formed float over a large number of warps.  The number of cross points on this fabric face thus is reduced, eliminating the tendency of the fabric to cause marking on sensitive paper qualities.
