Filed: 1966-10-07
Abstract: 1,089,817. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 7, 1966 [Nov. 2, 1965], No. 44809/66. Heading H1T. [Also in Division H3] A data storage device consists of two thin magnetic films having parallel easy axes and different critical switching fields, and means for applying a biasing magnetic field to rotate the magnetization of one film towards the hard axis without substantially rotating the magnetization of the other film. In Fig. 1 the storage film 12 has a critical field H KS  of 5À0 oersted and the switching film 14 has a critical field H KL  of 0À5 oersted. The films are evaporated on to a non-magnetic substrate and are separated by a layer 13 of SiO 2 . The biasing field, which may be supplied by a conductor parallel to the easy axis, by a coil or by a permanent magnet, may be applied continuously or only prior to and during a read operation. For read-out if the biasing field is equal to H KL , an equal and opposite field of 0À5 oersted is applied by passing current through a word line, allowing the magnetization of the switching film to fall back to the easy axis in a direction determined by the direction of magnetization of the storage film. The polarity of the output voltage induced in a sense line parallel to the hard axis indicates the data stored. For writing, a word field equal to or greater than the sum of H KS  and the biasing field is applied simultaneously with a bit field parallel to the easy axis, so that the magnetization of the storage film is switched. The bit field preferably terminates, and may start, later than the word field. A matrix is described (Fig. 5, not shown) having either separate or common bitsense lines.

Abstract: 1,236,610. Dicalcium phosphate; ammonium nitrate. ENTREPRISE MINIERE ET CHIMIQUE. 26 Sept., 1968 [7 Nov., 1967: 22 Nov., 1967], No. 45834/68. Heading C1A. Dicalcium phosphate is prepared from a mixture of phosphoric and nitric acids with the molar ratio (H 3 PO 4 : HNO 3 ) of 0À5-9À0, by precipitating the phosphate by adding a calcium compound until the ratio CaO: P 2 O 5  is about 2, and then adding ammonia to a pH of 6-7, in the presence of 5-35% by wt. of a primary, secondary, or tertiary aliphatic alcohol, or a mixture of these, having up to 8 carbon atoms per molecule. As shown, phosphate ore in line 1 is fed to reactor 2 at 80 C., which is also fed, at 3, with HNO 3 . The solution produced is cooled, and crystals of Ca(NO 2 ) 2 .4H 2 O collected in line 6. The mother liquor (containing some Ca(NO3) 2 ,  HNO 3 , H 3 PO 4  and impurities) is passed by line 7 into liquid-liquid extraction battery 8, which is fed by line 9 with a solvent containing aliphatic alcohols (e.g. OXO alcohols), HNO 3 , NH 4 NO 3  and water. The raw extract (containing all the H 3 PO 4 , most of the HNO 3 , some Ca(NO 3 ) 2  and some impurity), is contacted in 11 with a HNO 3 /H 3 PO 4  solution containing NH 4 NO 3  from line 24. Purified extract is passed to third extraction battery 13, and contacted with the aqueous solution in line 14 from the filtrate and washings of the final CaHPO 4 . An aqueous solution containing H 3 PO 4  and HNO 3  is obtained in line 15, and about half of this solution is passed to neutralizer 17, fed with Ca (NO 3 ) 2 .4H 2 O from line 6, and the pH adjusted by NH 3  from line 23. The slurry of CaHPO 4  is passed to filter 20 where the precipitate is washed, and CaHPO 4  product is removed in line 22. The organic phase leaving 13 in line 33 is mixed at 25 with more HNO 3 , and at 26 with more alcohol, and recycled to 9. The second part of the HNC 3 /H 3 PO 4  solution in 15 is passed to 11, thence to 8 and eventually, containing Ca(NO 3 ) 2  and NH 4 NO 3 , fed to distillation column 29, the alcohol distilled off and recycled to 26, and the raffinate drawn off at 30 and added to the Ca(NO 3 ) 2 .4H 2 O excess not used in 17, giving, at 31, a mixture of Ca(NO 3 ) 2  and NH 4 NO 3  in solution which may be concentrated and granulated, or may be treated with CO 2  and NH 3  to give an NH 4 NO 3  solution and a precipitate of CaCO 3 .

A method of laying a pipe line 14 from a floating vessel 10 comprises the steps of lowering the pipe line from the vessel to the floor 18 of a body of water and moving the vessel in the direction in which the pipe line is to be laid, while maintaining at a predetermined distance off the floor a guide weight 20 slidably attached to the pipe line and maintaining the pipe line adjacent the guide weight at an angle to the vertical within predetermined limits. As shown, the vessel 10 is provided with a derrick, mast or other lifting means 11 and two propulsion units 12, 13, the pipe line 14 having a landing platform 15 adapted to engage the floor 18 and marked by a buoy 17. A string of buoyancy chambers 23 are secured over the pipe line and connected to the guide weight and the latter is suspended from the vessel by lines 21, 22 or a single tubular member surrounding the pipe line, one of the guide lines having attached thereto a tiltmeter 25 for measurement of the angle of deflection of the guide line from the vertical in two planes at an angle to each other. The guide weight carries, a depth meter 24 or measuring sheaves are used to indicate the length of guide line used in supporting the weight. As the vessel is moved away from the position in which the pipe line was vertically lowered the pipe line having been anchored firmly on the bottom 18 by the platform 15 the pipe line assumes a radius of bending depending on the placement and buoyancy of the chambers 23; the angle a between the guide line 22 and the vertical is kept constant by the tiltmeter and is so chosen to mimimize the bending stress placed on the pipe line, the guide weight providing a uniform forward thrust to the pipe line and being maintained at a predetermined depth. The signals from the tiltmeter are accepted by a control system to adjust the propulsion units 12, 13 and thus the course of the vessel. In a modification the pipe line is carried coiled on a drum mounted in the vessel. Specifications 922,919 and 994,995 are referred to.
