Title: Process for the recovery of boric acid from oxidation mixtures of the liquid phase oxidation of hydrocarbons
IPC: C07C35/02
Filed: 1965-02-11
Abstract: Boric acid is recovered from the mixture produced in liquid phase oxidation of hydrocarbons by O2 or a free-O2 containing gas in the presence of boron compounds, by heating the mixture with 1-10 times its weight, referred to B calculated as boric acid, of an aliphatic monohydric alcohol having 1-4 carbon atoms, separating alcohol, saponifying the resultant boric ester with water and separating the boric acid.  The alcohol e.g. methanol, ethanol, propanol, t-butanol, may be passed as vapour up through the oxidation mixture heated to 80-160 DEG  C., in a column filled with Raschig rings, the azeotrope of ester and alcohol collected, and excess alcohol recycled.  0.1-1% of an alkaline reagent, e.g. NaOH, or Al(OH)3 may be added to the oxidation mixture before the heating.

Title: Method and device wherein the ejection of workpieces by a machine controls the machine

Abstract: 975,815. Presses. SOC. ORNANAISE DE CONSTRUCTIONS MECANIQUES. Feb. 20, 1961 [May 10, 1960], No. 6224/61. Heading B3H. [Also in Division G4]  The sound made by a workpiece ejected from a machine in falling on to a tray or sheet-metal plate is converted into an electric current, which current is utilized to control the initiation of the next cycle of operations of the machine. In normal operation the sound is received by the microphone 4 and the resulting current, after amplification by the double triode 5, operates relay 9. Relay 12, which follows, locks up, energizes and electromagnet 44 of the electromagnet clutch of the machine, which also incorporates the normally closed limit switch 45, and lights the green " Operation " tell-tale lamp 16. Relays 30 and 32, the latter being slow-to-operate, come up in parallel with electromagnet 44 and short circuit the capacitor 35. At the end of the cycle of operations the limit switch 45 opens, thus de-energizing the electromagnet 44 and releasing relays 30 and 32. The discharged capacitor 35 is thus connected in parallel with relay 12 and its charging circuit effectively short circuits relay 12, which releases and restores the apparatus to its initial condition. Starting operations with a workpiece on the working table.-Manual closure of push-button switch 23 brings up relay 17 which locks up, lights the red " Start " tell-tale lamp 22 and energizes the electromagnet 44, the operations then proceeding as described above. Starting operations with no workpiece on the working table.-Manual closure of push-button switch 28 brings up relay 28a which locks up, operates relay 17 which initiates a first cycle of operations, and relay 29a which holds relay 17 at the end of that cycle so that a second cycle is initiated, whereafter operations proceed as described above.

Abstract: 1,174,663. Audiovisual reproduction apparatus. MARVIN IRVING GLASS, [trading as MARVIN GLASS & ASSOCIATES]. 9 Feb., 1967 [3 June, 1966], No. 6248/67. Heading G5R. [Also in Division G2] An audiovisual device for viewing photographic transparencies and reproducing an accompanying sound comprises a housing with a light-gathering lens 22 (Fig. 1), a disc carrying circumferentially arranged transparencies and a relatively rotatable sound record disc, and sound reproducing mechanism including a stylus indexable relative to the record. As described, the device is for viewing stereoscopic transparencies and the stylus is automatically positioned at the start of a message pertinent to a selected transparency pair. The transparencies 34 (Fig. 3) are mounted on a holder 28 carrying a rotatable sound record 32 of translucent material to form a record unit as in Specification 1,174,664. The unit is inserted through a slot 24 and rests against ribs 66 (Fig. 11) and against a rotatably mounted plate 42. A tongue 58 on the plate 42 engages slots 62 in the holder 28 to rotate the latter when lever 30 is depressed to align a selected transparency pair with apertures 56, 82 and viewing tubes 18. At the same time, a lug 164 on plate 42 engages a shoulder 162 on arm 134 to rotate the arm about its pivot 148 so that a pawl 154, passing through a slot 156 in a cover-plate 144, engages a first rack 158 to advance a guide 132 by which the tone arm 88 is indexed. The arm 134 and guide 132 are return-biased by springs (150, Fig. 7, not shown), and 172 respectively, but the rack 158 is held in its advanced position by engagement of a pawl 166 with a second, lower rack 160 attached to the first, the racks and guide 132 forming a unit slidable in guides 136. The pawl 166 may be disengaged by depression of a button (170, Fig. 5, not shown) to set-zero the stylus. A battery-powered motor 84 and a flywheel 92 which it belt-drives are mounted on a bracket 96 pivoted by lugs 102 in sockets 104 in the plate 64. A button 40 is depressed to pivot the assembly against a spring (115, Fig. 4, not shown) which co-operates with contacts (113), (114) to energize the motor only when a clutch face 107 of the flywheel shaft 106 (also Fig. 3) has engaged a shaped recess 108 in the record. The tone arm 88, normally held away from the record by an arm 159 on the motor bracket 96, is guided to the start of the message by a cam surface 140 (Fig. 10) of the stylus guide 132. On release of button 40 during, or at the end of, the message, the arm 159 raises the stylus from the record and a second cam surface 142 of the stylus guide 132 returns the tone arm to a position where the message may be repeated. The messages are separated by continuous grooves so that only the message pertinent to the selected transparency pair is played. The tone arm 88, spring-pivoted at 118, 126, 128, bears against a ledge 124 formed on a plastics sound cone, the record grooves being vertically modulated.

Abstract: 1487666 Hydrotreating catalysts LABOFINA SA 17 Feb 1975 [18 Feb 1974] 6644/75 Heading B1E A catalyst for hydrogenating petroleum fractions comprises forming an aqueous mixture comprising alumina hydrogel, alumina hydrosol and at least one water soluble ethylenic monomer whose homopolymer is water soluble or forms a gel and dispersing the mixture as aqueous droplets in a hot, substantially water immiscible fluid and allowing the monomer in each droplet to polymerise, thus agglomerating the alumina hydrogel and hydrosol to form beads, and finally separating the beads and subjecting them to a thermal treatment; there being incorporated into the beads either by addition to the aqueous mixture and/or to the beads before the thermal treatment, at least one oxide or sulphide of a Group VIII metal and at least one oxide or sulphide of a Group VIB metal or compounds which are capable of generating said oxides or sulphides (as a result of the thermal treatment). The groups referred to are of the Periodic Table in the 49th Edition of the Handbook of Chemistry and Physics, published by the Chemical Rubber Co. The hot fluid may be (i) a hot dry gas through which the droplets pass counter-current; (ii) a column of liquid whose density is lower than that of the formed beads (such as paraffin oil) and downwardly through which the hardening droplets fall; or (iii) a column of liquid whose density is higher than that of the formed beads (such as chlorinated diphenyl) and upwardly through which the hardening droplets are allowed to rise. The thermal treatment is usually drying followed by calcination. In the Examples catalysts comprising alumina beads containing the following catalytic constituents, are prepared: cobalt oxide and molybdenum oxide; cobalt oxide, molybdenum oxide and SiO 2  (additional support material); molybdenum oxide and nickel oxide; tungsten oxide and nickel oxide; and molybdenum oxide, nickel oxide and cobalt oxide.
