Abstract: A B S T R A C T           A mounting structure for the granulate hopper of the injection unit of an injection molding machine which is convertible for use with a selectively horizontally or verti-cally oriented injection unit, the structure comprising two joined, rotatable tubular connectors each with an oblique end face, the lower connector being seated on an inclined face of the mounting hub which holds the plastification cylinder, and the upper connector carrying the hopper.  The latter consists of a conical lower hopper portion and a cylindrical upper hop-per portion which is inclined against the former so as to have one common straight side line which is vertical in both confi-gurations.  Conversion adjustment is accomplished through ro-tation of the lower connector and of the hopper by 180°.

Abstract: ABSTRACT OF THE DISCLOSURE     The presence of microorganisms in a sample is determined by culturing microorganisms in a growth medium which is in contact with a measuring electrode and a reference electrode and detecting the change in potential between the electrodes which arises by the migration and accumulation of said microorganisms adjacent the surface of the measuring electrode thus forming a charge-charge interaction between said measuring electrode and accumulated microorganisms, by measuring the potential change with a high impedance potentiometer.  In this divisional application, the invention pertains to an apparatus for detecting micro-organisms.

Abstract: RECOVERY OF TITANIUM METAL VALUES                 ABSTRACT   Titanium metal values are recovered from a titanium bearing source such as an ilmenite ore by subjecting the source to a reductive roast and leaching the reduced source with a halogen-containing compound.  Following this the soluble metal halides are separated from gangue and the pregnant leach liquor is treated with an iron oxide such as ferric oxide to precipi-tate titanium dioxide.  The nucleation of the titanium dioxide may be im-proved by using a large excess of ferric oxide in the precipitation step The improvement will thus result in an increased yield of the desired titanium dioxide.

Abstract: ABSTRACT           A television cathode may picture tube has at least one electron gun for generating at least one electron beam for projecting at least one beam spot on the picture imaging screen of the tube.  The gun has a plurality of differently electrically charged electrodes having coaxially aligned openings therethrough for the passage of the beam.  The electrodes have juxtaposed faces defining at least one gap in Which is established a beam-focusing electrostatic field.  The tube is subject to influences which introduce an undesired distortion of the beam spot to the detriment of the quality of the image projected on the screen.  The electron gun is characterized by at least one of the electrode faces being mechanically deformed in the opening perimeter to cause the field to be azimuthally asymmetrical about the opening. The mechanical deformation is effective to act on the beam in a sense tending to at least partially compensate for the undesired distortion of the beam spot.

Abstract: Abstract of the Invention An improved ophthalmic lens made of refractive material and having varying focal length, said lens having two refractive surfaces one of which is divided into first, second and third viewing zones intended respectively for distant vision, inter-mediate vision and near vision.  The first viewing zone of the lens occupies substantially the upper half of said one surface and has a substantially constant curvature providing a substan-tially constant focal length for distant vision.  The third zone of the lens occupies the lower central portion of said one surface and has a substantially constant curvature providing a substantially constant focal length for near vision.  The second zone of the lens lies between the first and third zones and has a varying curvature providing a varying focal length, the curvature of the second zone varying progressively from the substantially constant curvature of the third zone.  The improvement in the lens consists in the novel manner in which the lens surface comprising the second viewing zone is generated so as to provide a uniquely configured, stratigically located intermediate viewing zone which is totally free of astigmatism and distortion.

Abstract: ABSTRACT      There are disclosed an apparatus and a method for continuously embossing synthetic plastic sheet material with precisely formed em-bossments in patterns repeating along the length thereof.  The appar-atus includes a movable polished belt upon which the sheet material is carried, and a series of molds are placed on the sheet material. As the sheet material and molds are advanced in steps through the apparatus, presses clamp the molds and belt against opposite surfaces of the sheet material and raise the temperature of the assembly to embossing temperature for the resin to cause the resin to flow into the mold cavities, and volatiles at the interface are dissolved in the resin.  After the embossing step, the clamping pressure is re-leased and this permits limited shrinkage of the mold and sheet material. At subsequent stations, controlled temperature reduction is effected, and limited shrinkage is permitted after the clamping pressure is released at each station and as the material and molds move to the next station.  Mold distortion is thus avoided and the embossments remain precisely formed.

Abstract: ABSTRACT OF THE DISCLOSURE         A container for liquids, semi-liquids, powders and similar flowable fluids comprises a substantially airtight body for storing the fluid, a means for varying the pressure of gas above the level of the fluid in the body of the container, e.g resilient flexible container walls such as a squeeze bottle, an air pocket structure disposed at the lower end of the container, and in free fluid communication with the body of the container so as to allow entry of fluid from the body of the container into the air pocket structure.  Air resides in the air pocket structure when the container is disposed with its lower end downwardly.  An outlet passageway has an upper end which communicates near the top of the air pocket structure to be disposed in air retained in the air pocket and a lower end open to atmosphere exteriorly of the container and the air pocket.  Such a container holds liquids therein without dripping.  To discharge the liquid or other fluid the pressure on the body is increased, so as to cause liquid to rise through the air pocket into the outlet passageway, and to issue therefrom.  Upon release of the applied pressure, air is sucked back in through the passageway so as to have a cleaning effect thereon.  The structure allows storage of liquid ready for dispensing, but without risk of leakage or dripping, even when exposed to fluctuations in temperature of considerable magnitude.
