  • Patent number: 5242202
    Abstract: A grabber for a wheel clamp of a wheel aligner has a tip including a body shaft with first and second wheel engagement ends. The body shaft includes a circumferential groove formed thereon. A barrel attached to a carrier of the wheel clamp has a bore sized to slidingly receive the body shaft. The bore has a groove formed in its wall. An elastic "O" ring is fitted within the body shaft groove and, when an engagement end of the shaft is inserted in the bore, the "O" ring resiliently retains the shaft within the bore. Alternatively the grabber tip includes first and second cross shafts, each with first and second wheel engagement ends. The first and second cross shafts and body shaft have axes which are mutually perpendicular.

  • Patent number: 5238664
    Abstract: Process for disposing of insoluble tailings that remain when solubilizing uncalcined or calcined trona in the process of producing soda ash, in which the tailings are slurried with water or waste solutions of sodium carbonate and/or sodium bicarbonate, adding an alkali metal hydroxide or alkaline earth metal hydroxide in effective amounts up to about 10% by weight of the aqueous slurrying solution, pumping the slurry into a well connected to an underground mined-out cavity with sufficient pressure to prevent build-up of tailings from plugging the bottom of the well opening, dispersing and settling said tailings in the cavity, removing a liquor from said cavity whose concentration of sodium carbonate and/or sodium bicarbonate has been increased and recovering such enriched liquor for use in the manufacture of sodium-containing chemicals such as soda ash.

  • Patent number: 5236492
    Abstract: A hydrometallurgical process is described for recovery of a precious metals from ores refractory to treatment by lixiviating agents by crushing the ore to no finer than a nominal 1/4 inch size, acidifying the ore with a mineral acid, treating the ore to a preliminary oxidation with nitric acid, optionally adding a binder to the oxidized ore, heap treating the ore with nitric acid to complete oxidation of the ore, water washing the heaped ore, optionally increasing the alkalinity of the heaped ore, heap treating the ore with a lixiviating solution and recovering precious metals from the lixiviating solution. The process recovers NO.sub.x gases generated during the preliminary oxidation and binder addition stage for conversion into nitric acid which is recycled for treating ore. Chemical treatments in the process can be carried out at ambient temperatures and atmospheric pressures.

  • Patent number: 5233328
    Abstract: A method for processing compacted data without converting the data into uncompacted form. A first set of digital data is converted into compact form by recording a set of points at which the signal level changes. A second set of digital data is likewise converted into compact form by recording the points of signal level change. A logic function is then used to compare the first set of compact data with the second set of compact data.

  • Patent number: 5232620
    Abstract: A granular STPP suitable for detergent compositions which is non-caking in non-agitated water is produced by wetting anhydrous phase II STPP granules and drying the granules to remove free water.

  • Patent number: 5230688
    Abstract: The invention has to do with the modification of well known heat sealing bag machines to increase the production capability of the machines. The use of servo drives for selected components of the bag machine permits the reduction of film acceleration and consequential peak film velocity, thus allowing faster machine cycles at the same film acceleration and consequential film velocity.

  • Patent number: 5231242
    Abstract: The apparatus disclosed herein relates to plasma injection and distribution systems which release high energy plasma into a combustible mass to promote efficient combustion and maximize the muzzle velocity of a projectile. The devices inject plasma streams into a combustible mass in a coherent and directed manner such that pressure peaks and the resultant thermal and dynamic stresses are eliminated. Particularly, strategically positioned outlet orifices and nozzles enable the invasion of a propellant mass by plasma jet streams to create controllable uniform ignition and combustion therein.

  • Patent number: 5225624
    Abstract: The apparatus and method disclosed herein relates to the generation of primary and fuel-enriched plasma to provide ignition and delivery for large amounts of electrical and electrothermal power to a propellant mass. Particularly, the present invention enables the creation of zones of controlled combustion by initially incubating primary plasma in a capillary chamber and mixing the primary plasma with fuel in a fuel chamber thus creating a fuel-enriched plasma. The primary plasma and the fuel-enriched plasma are segregatively, collectively and substantially simultaneously injected into the propellant mass via outlet ports and nozzles. The capillary and fuel chambers, and the nozzles and outlet ports undergo staged disintegration at reaching predetermined pressures and temperatures and are thereby consumed in the combustion process.
