Filed: 1962-12-18
Abstract: 988,189. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 18, 1962 [Dec. 18, 1961], No. 47705/62. Drawings to Specification. Heading H1K. [Also in Division H3] A magneto-resistive unit is described which consists of a thin film of magneto-resistive ferromagnetic material which has been vapour deposited on to a glass substrate and provided with Woods metal contacts to which two leads are connected. The resistance of the unit varies with the angle made by an applied magnetic field (irrespective of its polarity) with the direction of current flow through the unit. In a storage unit two orthogonal coils are provided so that magnetic fields can be selectively applied, in the plane of the film, parallel and perpendicular to the direction of current flow. The application of a current pulse to the coil causes the film to change to a resistance state other than that in which it is not magnetized and it remains in this state until switched to a second stable state by a pulse applied to the other coil. The unit may be placed in one arm of a resistance bridge which is balanced for the non-magnetized state of the unit but which when the unit is magnetized provides an output showing the state of the unit. A multiple store makes use of many magnetoresistive units which are connected in turn to such a resistance bridge by a multiplexing unit.

Abstract: 1,173,014. Purifying metals and alloys. AIR REDUCTION CO. Inc. Nov. 1, 1966, No.48825/66. Heading C7D. In a method for the production of a highly purified refractory metal (V, Nb, Ta, Mo, W, Zr, Hf, Re), lanthanide rare earth metal, actinide rare earth metal, or alloy thereof, from a mixture of the metal with an impurity which cannot be separated from the metal by vaporization at a reduced pressure without causing vaporization of the metal, the mixture is heated in an electron beam furnace at a pressure of not more than 1000 microns Hg to form a molten pool, the molten pool is contacted with oxygen or a C 1-3  hydrocarbon gas which reacts with the impurity to form a vaporizable compound, and the latter is vaporized without vaporizing the metal. The process may be effected on intermediate products resulting from treatment of metal oxide raw material with reducing agents such as disclosed in Specification 1,173,015. As shown, metal oxide plus reducing agent in iron boxes 16 are melted in region 18 of furnace 10 by the action of electron beam guns 36. Volatile impurities and iron are vaporized off and condensed, and the melt then flows into region 20 in which heating is effected by electron beam guns 38 to vaporize further impurities. Reactive gas is then introduced through pipes 80, 82 further to purify the melt which then flows into region 22 to form ingots in mould 94. Pressures are preferably maintained at 1-1,000 microns Hg in region 18, and at not more than 2 microns Hg in regions 20, 22, by pumps 30, 32, 34. The examples relate to the purification of Nb, Mo, U, Ta - 10% W, and Ta.

Title: Method and apparatus for extracting a solvent
IPC: B01D61/00
Filed: 1975-11-28
Abstract: The solution to be fractionated flows under pressure within a concentration chamber (2) along a semi-permeable membrane (4) or, on operation with individual charges, lies against this. The solution produces the concentrate as a result of the loss of solvent. Solvent passes through the membrane (4) into an absorption chamber (3) and forms therein an additional solution with a working gas which it takes up by absorption. The additional solution, on depressurisation in a flow obstacle (12) passes from the absorption chamber (3) into a desorption chamber (7) in which, as a consequence of the depressurisation, it releases the working gas again. The desorbed working gas can be recompressed in a compressed gas transporter (8) and fed to the absorption chamber (3). The membrane (4) must only be permeable to the solvent and should retain on the one side the material dissolved in the concentrate and on the other side the working gas. The working gas, in the absorption chamber (3), is at a pressure which is higher than the osmotic pressure in the concentrate with respect to the pure solvent. Complete pressure relief of the membrane (4) is aimed at. <IMAGE>

Filed: 1965-11-19
Abstract: 1,130,343. Sewing machines. UNION SPECIAL MASCHINENFABRIK, G.m.b.H. 19 Nov. 1965 [20 Nov., 1964], No. 49137/65. Heading D1G. In a differential feed mechanism the strokes of two dogs may be varied independently,. and a reversing member sets both strokes to the same extent in the reverse direction even if the strokes had previously been different. The dogs are reciprocated vertically by eccentrics on the main shaft 10 connected to carrier arms 16. Each dog is reciprocated longitudinally by reciprocating arms 23 connected via links 26, 18 to the carrier arms. A slot 28 in bearing 27 at the end of each link 26 engages a block 29 fixed to a rotatable spindle. The spindles and blocks are rotated by rotation of adjusting shafts 41, so that movement of the arms 18 and thus the dogs are adjusted. Cam collars 56, secured to the adjusting shafts are engaged by pivoted followers 58, joined by a bridge 60. If each adjusting shaft is rotated by the same extent both followers lie on the collars, while if a differential feed is set one follower lies against its collar, and the other is spaced its collar. To reverse the feed direction a push rod 68 is lowered and pivots the followers by means of a collar 71 engaging the follower bridge, the one shaft is moved axially by its follower, until the other follower also lies against its collar. The feed strokes are thus equalised. Continued movement of the rod moves both shafts to the same extent until a pin on one shaft abuts a stop. The dogs are thereby set to an equal extent in the reverse direction. Either of the strokes of the dogs may be momentarily increased during forward feed by followers 64, selectively engaging the collars and pushing the shafts in an axial direction.

Abstract: 1282927 Purification of mixed carboxylic acids EL PASO PRODUCTS CO 10 Oct 1969 [18 July 1969] 49898/69 Heading C2C Products of the air oxidation of cyclohexane are separated and recovered from the mixture by a process involving extracting with water and separating the aqueous and organic phases; concentrating the aqueous phase and reacting with nitric acid at 30 to 60 C. to initiate oxidation and hydrolysis, and then at 75 to 125 C. to complete the oxidation; cooling and contacting with water-miscible alkyl alcohol (1-10 C) to form an alcoholic mixture including esters of acids present; extracting with water-immiscible solvent, separating and recovering esters from the organic phase. The process may be carried out continuously by distilling and recycling the solvent from the ester extraction; stripping and recycling the excess alcohol from the aqueous phase and recycling the aqueous nitric acid. A nitric acid concentration of 40-60% is preferred and air may be introduced to the oxidation step. An example describes, with a flow sheet, the separation of the esters dimethyl oxalate, succinate, glutarate and adipate. The organic phase of the process, purified to remove cyclohexane yields a feed of cyclohexanol and cyclohexanone to be oxidized by nitric acid to adipic acid. Methanol is used as the alcohol and benzene as the extractant and the raw material is cyclohexane oxidation by-product.

Abstract: 1305959 Checking optical systems INTERNATIONAL BUSINESS MACHINES CORP 21 Oct 1970 [5 Nov 1969] 49919/70 Heading G1A Photo-electric apparatus is used to check operation of an optical beam recording system. In the arrangement of Fig. 1 the recording system, operated under computer control, comprises a laser source 10; a half wave plate 12 correcting the polarization of the beam to a predetermined orientation; an electro-optical modulator, e.g. of the crystal type, having transparent electrodes attached to its faces, passing light of a controlled intensity; a plural stage light deflector, each stage of which comprises an electro-optical polarization control device, e.g. a KDP crystal, and a birefringent crystal, e.g. of caliste, the deflector being controlled from 17 to aim the beam where required on a recording medium 18, e.g. a photographic roll film. During the intervals while the film is stepped on, checking is performed by use of arrangement 22 and devices 26, 28. The electro-optical device 23 e.g. a calcite birefringent crystal with transparent electrodes, is energized causing a change in the orientation of polarization of the beam incident on birefringent crystal 25 so that this deflects the beam on path 26 to photo-sensitive diode 27 instead of allowing the beam to pass to the record medium. If the detector output is below a predetermined level a fault is indicated. This may be due to loss of power from the laser or faults in the modulator or drive 17.  In an alternative arrangement the device 22 is a beam splitter followed by a mechanical or electro-optical shutter which is closed during checking. No isolate malfunctions in the deflector drive circuit, this is shut down, and a further detector used to sense the deflected intensity which now results from deflection from a different point on birefringent device 25.
