Abstract: Abstract of the Disclosure This invention relates to a mineral-resin matrix useful as a mould-ing composition or as a putty or binder for combining coarser mineral par-ticles to produce articles or semi-manufactures having excellent mechanical properties, such as high strength.  The matrix of the invention consists mainly of mineral particles coated with a minor amount of a resin.  The mineral particles preferably used are crystallized glass, possibly in combina-tion with other particles having rough surfaces such as sand, ground cement clinkers, ground glass, ground tiles and bricks, and similar materials, poss-ibly in admixture with particles of less hard minerals such as limestone, talc, gypsum, pumice, dry clay, china clay and the like.  The particle size of the mineral can be varied to suit the use.  For most purposes a particle size of from 0 to  150 µm has proved advantageous.  Other particle sizes can be used, such as up to 250 µm.  Particles having an ideal fineness characteristic are preferred.

Abstract: RESIN-CONTAINING CELLULOSIC OVERLAYS                    ABSTRACT OF THE DISCLOSURE         Disclosed are improved resin-containing cellulosic overlays for overlaying woody substrates and processes for pre-paring same.  The overlays are produced by admixing an aqueous slurry of cellulosic fibers and a resole resin produced by reacting bisphenol A, a para-substituted phenol selected from p-tertiarybutylphenol, p-tertiaryamylphenol and p-phenylphenol and formaldehyde, precipitating the resin by acidifying the resulting slurry, forming a sheet from the resin-containing slurry and drying the sheet.  The overlays produced are white in color and are highly resistant to discoloration due to exposure to sunlight, heat and caustic.

Abstract: ABSTRACT OF THE INVENTION The recoverability by cyanidation of the gold content of sedimentary gold-bearing ores containing organic carbonaceous material and gold-bearing pyrite, or other gold-bearing sul-fides, is greatly increased by heating an aqueous slurry of the ore to about 167° to 212°F. and then introducing air or oxygen into the heated slurry to oxidize and eliminate a substantial portion of the carbonaceous material and oxidizable sulfides in the slurried ore, followed by cooling the slurry to about 70° to 85°F. and then introducing chlorine gas into the slurry to substantially complete the oxidation and chlorination of the carbonaceous content of the slurried ore. The ore is then sub-jected to conventional cyanidation to recover the gold content thereof.

Abstract: ABSTRACT OF THE DISCLOSURE   Novel higher dialkyl dimethyl ammonium clays, of superior gellant effectiveness in oxygenated organic liquids, can be produced by the over-treatment of layer and chain type mineral clays via ion exchange reactions. For example, a layered dioctadecyl dimethyl ammonium montmorillonite, a superior gellant for alkyd resin based coatings, is prepared by the reaction of sodium montmorillonite with a 12 to 25% excess of the corresponding quat-ernary chloride beyond the known ion exchange capacity of the clay.  The overtreatment is preferably carried out in a mixtureof water and organic solvent which disperses the clay and dissolves the quaternary ammonium salt.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosed friction disc transmission includes a conventional drive disc rotatable about a vertical axis and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis.  The friction disc is rotatably supported on a pivot frame having a sprocket drive connected to a sprocket on the wheel axle.  The wheel axle sprocket in the self-energizing transmission is located verti-cally below the drive sprocket and the drive sprocket is located between the frame pivot axis and the friction disc.  The tension in the drive chain thereby compresses the fricition disc into en-gagement with the drive disc in proportion to the torsion in the wheel axle and eliminates the requirement of a spring.  Other improvements include the novel chain drive including a driven sprocket on the pivot frame.

Abstract: A METHOD OF BUILDING A RADIAL TIRE    Abstract of the Disclosure A method of building a radial tire by first molding and vulcanizing a beltless radial tire casing which can be composed of carcass plies, tire beads, sidewall and undertread stock.  A narrow, inextensible band is centrally disposed around the outer periphery of the beltless tire. m e band is narrow enough not to radically change the operational characteristics of the belt structure, but wide enough to restrict expansion of the tire casing beyond a desired diameter for receiving the belt structure and tread. A belt structure composed of a plurality of belt plies, separate from the narrow band, is then positioned around the tire after which a tread is secured around the belt structure.  The assembly of tire casing, band, belt struc-ture, and tread is then placed in a mold where the belt structure and tread are molded and vulcanized.

Abstract: ABSTRACT OF THE DISCLOSURE A trigger device for use in the inflation of an inflat-able flotation rescue device such as a life jacket includes a casing containing a passage for receiving a compressed air container closed by a frangible diaphragm, and a pin for rupturing the diaphragm.  The pin is moved against the diaphragm by a first lever, one end of which is connected to the pin and a spring bearing against the lever near the other end thereof.        The first lever is held in a cocked position by a trip lever which engages such other end of the first lever and a water soluble stop which holds the trip lever and consequently the first lever in the cocked position.  Upon immersion in water, the stop dissolves, tripping the lever system to cause the pin to rupture the diaphragm.  The connection between the first lever and the pin is such that the pin describes a reciprocating movement, rupturing the diaphragm and then withdrawing from the opening.  A third lever-permits manual operation of the trigger device.  The third lever engages the one end of the first lever for moving such one end and the pin towards the diaphragm.

Abstract: GUIDE RAIL EXTRACTOR FOR MOLDED PLASTIC ARTICLES       Abstract of the Disclosure Article unloading apparatus is disclosed for use with a molding machine, the molding machine comprising first and second mold members reciprocally movable relative to one another between mold-open and mold-closed positions.  The article unloading apparatus comprises a pair of guide rails movable apart to a retracted position and toward one another to an article receiving position.  The pair of guide rails and the mold members are coupled together such that movement of the mold members to the mold-closed position, for molding an article, causes the guide rails to move to their retracted position in which they do not interfere with the molding operation.          Movement of the mold members to the mold-open position, for unloading the molded article, causes the guide rails to move toward one another and between the mold members to their article receiving position.  In the article receiving position, the guide rails are spaced from but in register with an article molded by the mold members.  An ejecting mechanism ejects the article to the guide rails which guide  the article away from the molding machine.

Abstract: ABSTRACT OF THE DISCLOSURE      A clock system for providing rectangular wave forms or wave trains, with each wave train having a selectable predeter-mined clock cycle period.  A rectangular wave train is generated by a generator comprising a delay line coupled to an INVERTER.          By using a second delay line to delay the rectangular wave by a selectable predetermined delay period, a control signal is formed which when fed into the generator produces a second rectangular wave train with a clock cycle period equal to that of the rectangular wave clock cycle period plus the period of the second predetermined delay.  The addition of a synchronization circuit permits the clock cycle period to be dynamically selected during a clock cycle.  This provides a rectangular train with the period of each clock cycle being any of the predetermined clock cycle periods independent of the clock cycle period of preceding or succeeding clock cycles.
