Title: Improvements in or relating to the production of chemical conversion coatings upon aluminium and its alloys
IPC: C23C22/38
Filed: 1960-12-09
Abstract: In a process for the production of a chemical conversion coating upon aluminium or aluminium alloy surfaces by treatment with an aqueous acidic solution having a pH of 0.8-4.5 and containing 0.15-12.5 g./l. of fluoride, 3-60 g./l. of hexavalent chromium expressed as CrO3, and 2-285 g./l. of phosphate and/or arsenate expressed as PO4, the dissolved aluminium content which tends to accumulate in the solution as a succession of surfaces are treated is controlled and maintained at any desired value by intermittently or continuously estimating the concentration of dissolved aluminium present in the solution and precipitating, so as thus to remove from the solution, any amount thereof in excess of that corresponding to the desired concentration, in the form of sparingly soluble or substantially insoluble alkali metal fluoaluminates, by adding thereto the amount of alkali metal ions proportionate to the excess quantity of aluminium to be removed in the ratio of 3 mols. of alkali metal ions per mol. of excess aluminium.  The alkali metal ions are preferably added in the form of a mixture of potassium and sodium ions in a molar proportion of 2 mols. of potassium per mol. of sodium, and may be introduced in the form of hydroxides, fluorides or carbonates.  Precipitation and removal of excess aluminium may be effected upon a withdrawn portion of the main coating bath in a subsidiary tank and the regenerated portion then re-united with the bath.  Replenishment of the bath may simultaneously be effected in the subsidiary tank.  The bath is preferably made-up and replenished by use of free acids. Specifications 632,097, 632,102, 708,937, 803,405, 832,485, 851,027 and 891,910 are referred to.

Title: Mist spinning process for acrylonitrile polymer filaments
IPC: D01D5/06
Filed: 1965-10-11
Abstract: 1,120,786. Mist-spinning polyacrylonitrile filaments. MONSANTO CO. 11 Oct., 1965 [12 Oct., 1964], No. 42987/65. Heading B5B. A process for spinning continuous aorylonitrile polymer and/or copolymer filaments is characterized by spinning an acrylonitrile polymer and/or copolymer filament-forming solution to form continuous filaments, and successively advancing the filaments first through a mist filled semi-coagulation zone and thence through a liquid coagulation bath. Thus in apparatus as shown, the solution is extruded through a spinneret 10 into a coagulating bath 12 to form filaments, the spinneret being enclosed in a chamber 22 and positioned at a level from ¢ inch to 4¢ inches above the coagulating bath, an atomized fluid being introduced into the chamber to establish a mist atmosphere, by means of spray nozzles 26, and filaments after the mist treatment are passed through the coagulating bath 12 and are withdrawn over a pair of bars 28 and via stripper bar 30 before passing over take-up rolls 32. A clearance is provided around round arm 20 at opening 18 and between cylinder 14 and the bath 12 to permit the exhausting of air from chamber 22. The chamber remains completely saturated with the atomized liquid at all times so that all surface areas of the filament are exposed to the mist atmosphere. Filaments of polymers and co-polymers of acrylonitrile may be so spun, using a fluid spray of water, or dimethyl acetamide, or of a mixture of water and dimethyl acetamide. The provision of the mist atmosphere makes possible the imposition of a greater drawing force on the filaments in the jet stretching stage than is possible by conventional dry jet wet spinning techniques. Suitably, the fiaments are withdrawn from the coagulation bath at a rate producing a jet stretch of from 1.0 to 6.5 times. An additional stretch of e.g. 1.5 to 6.2 times may be provided during washing.

Title: Purification of cyclohexane oxidation products
IPC: C07C/
Filed: 1960-12-14
Abstract: Cyclohexanol and cyclohexanone of improved purity and yield are recovered from an oil fraction, obtained by partial oxidation of cyclohexane followed by removal of unreacted cyclohexane and of a heavy ends fraction, by a process comprising the steps of mixing the oil fraction with an aqueous alkaline solution, agitating the mixture, allowing the mixture to separate into an organic phase comprising cyclohexanone and cyclohexanol and an aqueous phase, and separating the organic phase from the aqueous phase. The agitation may be carried out for a period of 5-60 minutes at a temperature of 100-0 DEG C. The alkaline solution may be a solution of sodium, potassium, or lithium hydroxide. The organic phase separated from the aqueous phase is preferably centrifuged to remove residual aqueous phase therefrom. The separated organic phase is distilled to obtain substantially pure cyclohexanone as overhead product, and a bottoms fraction containing cyclohexanol, or a fraction consisting of substantially pure cyclohexanol. If desired, the cyclohexanol may be subjected to dehydrogenation to produce cyclohexanone.

Abstract: 1,248,033. Indicating device. SMITHS INDUSTRIES Ltd. 20 Sept., 1968 [25 Sept., 1967], No. 43632/67. Heading G5C. [Also in Division H1] Member 13, which may be of circular or polygonal cross-section, is movable to a plurality of discrete positions I-III wherein different arrays of markings are displayed at a window 11, each marking describing a function that will be performed when one of the switches 10a-10j is operated. Means for performing the functions, such as a computer and an aircraft navigation system, Fig. 2 (not shown), are such that the function performed depends both upon which switch 10 is operated and which of the faces of member 13 is displayed. These means are conditioned by a first switch operation to respond to a subsequent switch operation in a manner dependent also upon which switch was operated in the first switchoperation, as in the following example. Operation of switch 10a adjacent the designation "NAV" causes a signal to be fed to a computer (18), Fig. 2 (not shown) which in turn energizes a motor 14 to rotate member 13 to display face II upon which are various designations corresponding to navigational aids available for use. Operation of a switch now adjacent one of these causes the computer to display at an indicator panel (16), Fig. 2 (not shown), information appropriate to this aid. The computer is conditioned so that a navigational aid can only be selected in this way if the "NAV" switch was operated previously. Face III of member 13 could bear numerical data corresponding in a similar way to, say, the designation "HDG" on face I. Reference is directed to the divisional Specification 1,248,034.

Switching circuits 32a, 32b are connected to the other conductors of the selection button whereby the pulses supplied from the deflection circuit 15 through touching a selection button 12a corresponding to a desired channel actuates the associated switching circuit 32a so that the output of a constant voltage source 4 is supplied to the electronic tuner 7 through a voltage adjuster 14a connected to the switching circuit to select the desired channel. When the contacts of button 12a are touched by a finger a pulse 28, which occurs during the flyback period, from the horizontal deflection circuit 15 of the television receiver fires a thyristor 32a to connect a constant voltage source to provide a tuning voltage to the electronic tuner 7 via variable resistor 14a and a diode 6a. When another channel is selected by touching button 12b a thyristor 32b is fired and the change in voltage to zero at the anode of the thyristor 32a together with the charge retained across a capacitor 37a cut off the thyristor 31a. The tuning voltage corresponding to the button 12b obtained from a variable resistor 14b is then applied to the tuner 7. The diodes 31a, 31b may be removed. The deflection circuit 15 may be the vertical deflection circuit. The Specification refers to a prior art circuit (Fig. 1, not shown) where a voltage derived from the commercial frequency induced by touching a selected button (1a-1c) is amplified (2a-2c) and operates a flip-flop switching circuit (3a-3c) to switch in the associated tuning voltage adjuster for tuning selection and to a prior art circuit (Fig. 2, not shown) where an oscillator feeds one contact of the buttons.
