Title: Recovery of surface-active materials from petroleum wax oxidates
Inventor: ZALICHI DEMETRIOS THEODORE EMM
IPC: C10G73/42
Filed: 1958-10-31
Abstract: Polar liquids are emulsified with non-polar liquids and solid particles are disposed in liquids, there being used as emulsifying or dispersing agent surface-active material comprising longchain oxygenated material containing carboxyl and hydroxyl groups, some of which may be esterified, present in micro-crystalline wax oxidate and isolated therefrom in specified manner (see Group IV(b)).  Thus, carbon black may be dispersed in light petroleum or n-heptane. Aqueous solutions of inorganic salts may be emulsified in an oil. For example, an aqueous sodium nitrite is emulsified in a mineral lubricating oil and the water-in-oil emulsion is then dehydrated to provide a dispersion of crystalline sodium nitrite in the oil which may then be mixed with a grease.ALSO:Surface-active material present in microcrystalline wax oxidate is isolated by contacting the wax oxidate in molten form or in solution in an organic solvent with an acid-soluble, basic solid adsorbent, whereby the surfaceactive material is preferentially adsorbed on to the adsorbent, separating the loaded adsorbent from unadsorbed wax oxidate, washing the loaded adsorbent with an organic solvent for the wax oxidate and liberating the surface-active material from the washed adsorbent by dissolving the latter in an acid.  Suitable solid adsorbents are magnesium oxide and the oxides and hydroxides of calcium and barium.  The adsorbent may be intimately mixed with the oxidate or a solution of the oxidate may be passed through a column of the adsorbent.  Suitable solvents are n-heptane, benzene, acetone, isopropyl alcohol, chloroform and pyridine.  The washed loaded absorbent may be dissolved in hydrochloric or acetic acid and the liberated surface-active material consisting mainly of long chain oxygenated material containing carboxylic and hydroxy groups may be recovered by solvent extraction. The products are emulsifying agents.  An example is given wherein the oxidate is prepared by reacting the wax with oxygen at 150 DEG C. in the presence of lithium stearate as catalyst.

A lance for treating slag covered molten metal with a gas or solid entrained in a gas comprises a fluid-cooled conduit comprising three coaxial pipes providing an annular gas passage disposed between cooling fluid inlet and outlet passages, a nozzle joined to the conduit and having a central gas discharge passage communicating with the annular gas passage through a plurality of passages directed tangentially or intermediate the tangential and radial directions, with respect to the gas discharge passage and opening at spaced intervals along the gas discharge passage. As shown, a gas passage 43 is disposed between a cooling fluid inlet passage 50 and a cooling fluid outlet passage 58, a helix 64 being inserted in the nozzle end of the passage 58 to increase the speed of the coolant. The passages 50 and 58 are connected by a bore or bores 54 in the nozzle 30. Passages 42, 44, 46, 48 lead from the passage 43 to the discharge passage 32 of the nozzle, these passages 42-48 being tangential to the outlet 32 and preferably biased towards the opening at an angle A of 7-38 degrees.

Filed: 1973-07-24
Abstract: 1409350 Program interrupt handling BURROUGHS CORP 24 July 1973 [2 Jan 1973] 35173/73 Heading G4A A primary, re-entrant, interrupt handling procedure PIHP and a secondary interrupt handling procedure SIHP are stored in memory, the PIHP being recursively called for execution from its beginning in response to an interrupt signal, the number of recursive calls made on PIHP before completion of its execution is counted, and, if a predetermined count is reached, the SIHP is called. The PIHP and SIHP may be stored in different modules of memory 3, the arrangement avoiding endless looping if a failure prevents successful entry into PIHP. During execution of an object program, a register IML is in state 0, successive interrupt signals, either external, 11 or from alarm interrupt 21 signifying failure of an attempt to transfer data between a memory location and register 15, cause IML to be incremented. The memory 3 stores program segments as well as PIHP and SIHP and is organized to store information in push-down stacks-recording the execution of different procedures, a pointer to the top word in a stack is held in S register 64, and words from the B and A registers may be pushed down into the stack in that order. PIHP may include read and set operators to reset IML to one of its lower order states to enable an arbitrary number of recursive entries into PIHP to be made. Processing may be halted if the count in IML exceeds the predetermined number used for entry into SIHP. Details of hardware generation of calling sequences to PIHP and SIHP, and the generation of various stack markers and pointers and their insertion and retrieval from memory stacks, are described.

Abstract: 962,815. Spraying. STEWART-WARNER CORPORATION. Oct. 14, 1960 [Nov. 2, 1959], No. 35386/60. Heading B2F. [Also in Division F2] In an apparatus for generating an oil mist, the air is first passed through a heater. Air supplied by a compressor (not shown) is conveyed by conduits 6 to a water-separator 8; is passed through a manually-, or time switch-, operated solenoid-valve 24 to an air pressure regulator 10; and is allowed to flow through a conduit 44 to a heater 12, having an outlet 46 connected to an inlet 102 of a mist-generator 4 carried by an oil-reservoir 2 having a mistchamber 30, Fig. 2, therein. The heater has a body 40 having an outer shell 48 with ends 50, 52 and an inner shell 54 with ends 56, 58; and insulating material 60 is located between the outer and inner body members. The inner shell 54 supports a heat-exchange structure 62 comprising a U-shaped heater-element 64 having a helical heat-exchange surface 70 and terminals 66, 68 which pass through the end 58 of the body 40. The inner shell 54 also contains a baffle structure 72 having a central wall 74 and semicircular tranverse walls 76, 78 with apertures 80, 82 for receiving the element 64. The air temperature is controlled by a thermostatic safety switch 84 carried by the end 58 of the body 40. The mist generator 4, Fig. 2, receives air through the inlet 102 and the air is passed to a chamber 108,via apertures 106 and a chamber 104, the latter being sealed by a member 112 secured to a body 100 and having a central bore 114. The bore 114 leads to counter-bores containing elements 116, 118 having annular clearances therebetween which form a passage for the air to a chamber 120 and also produce a low pressure in the element 116. The element 116 is connected to a reservoir 2 by bores 114, 122, 124 and a tube 126 so that the pressure in the space 30 forces oil through the tube 126 and into the chamber 120 where it mixes with the air. The oil mist then passes into a baffle 132 having apertures 134 therein so that heavy particles are condensed and return to the oil in the reservoir, whereas the oil-mist passes into the chamber 30 from where it is applied to the surfaces to be lubricated. The pressure of the oil-mist in the chamber 30 is measured by a gauge 16 and a safety-valve 18 is also provided. The oil in the reservoir may be heated by a heater 22 controlled by a thermostatic switch 20.
