Abstract: 1,258,443. Titanium -dioxide. TITAN G.m.b.H. 29 Jan., 1969 [15 Feb., 1968], No. 5061/69. Heading C1N. In a process for making titanium dioxide by hydrolysis of a titaniferous solution of hydrochloric acid which has been obtained by digesting titanium ores with 32-38% strength hydrochloric acid, and freed from part of the iron by crystallization 1/10-1/3 of the titaniferous solution is slowly added to a seed solution heated to a starting temperature in the range of above 90<SP>‹</SP> to 100‹ C. while maintaining the starting temperature in the receiver over a time greater than 20 minutes x (V 1 /V 2 ). Where V 1  is the proportion of titaniferous solution thus added, and V 2  is the total volume of the solution to be hydrolysed, the resulting partial mixture then being mixed, before completion of the hydrolysis at about 105‹ C. With the remainder of the solution to be hydrolysed, if the volume of seed solution exceeds 20% of that of the total volume of solution to be hydrolysed, the volumn of the partial mixture is reduced by removing, as water or dilute hydrochloric acid, at least. that part of the volume of the seed solution that exceeds 20%. Hydrolysis may be completed by maintaining the mixture at 105‹ C. for ¢-3 hours. In one embodiment, the volume of the partial mixture is reduced irrespective of the volume of seed solution. The seed solution is defined as a titanium solution containing hydrochloric acid in which the molar ratio of free HCl to titanium dioxide is less than 4, the titanium dioxide content being 7-30 g./l. The solution may contain other metal ions e.g. iron, magnesium, alkali metals or alkaline earth metals. The residual hydrochloric acid, after completion of the hydrolysis and separation of hydrated titanium oxide, may be recycled for use in a subsequent digestion after restoring its concentration, without further decrease in volume, by adding a hydrogen chloride-steam mixture produced by thermal decomposition of the iron choride removed from the digestion solution. In examples the hydrated titanium oxide is calcined, with addition of K 2 O, and ground.

Abstract: 1, 264,348. Nuclear magnetic resonance magnetometers. COMMISSARIAT A L'ENERGIE ATOMIQUE. Oct. 14, 1969 [Oct. 17, 1968], No.50302/69. Heading G1N. A magnetometer for use on board an aircraft having means for compensating for parasitic magnetic fields comprises means delivering a voltage e 1  proportional to the total magnetic field at a point 1 distance x+ #x from the barycentre 4 of the perturbing fields, means delivering a voltage e 2  proportional to the difference between the total magnetic field at point 1 and the total magnetic field at a point 2, distance x from the barycentre, an adjustable-gain amplifier 16 for multiplying e 2  by a factor depending on x to generate a third voltage e 3  proportional to the intensity of the perturbing fields at point 1 with the same proportionalitv factor as e 1 , and means 18 for subtracting e 3  from e 1  to generate a voltage e 4  proportional to the magnetic field being measured. In Fig. 5, the output of a magnetometer 3 of the nuclear magnetic resonance spin oscillator type is amplified at 7 and fed to a frequency meter 5 which produces the voltage e 1 . The output of amplifier 7 is also fed to a nuclear magnetic resonance filter 8 which produces a phase shift proportional to the difference in field strength at points 1 and 2. The output of filter 8 is amplified at 14 and compared in phase meter 11 with the output from amplifier 7 to produce the voltage e 2 . Alternatively, a second spin oscillator (3a), Fig. 8 (not shown), may be used instead of nuclear filter 8, a differential frequency meter (31) being used instead of phase meter 11. Coils (28), Fig. 6 (not shown), may be energized to make the barycentre of perturbing fields due to eddy currents coincide with that due to ferromagnetic masses. Preferably, points 1 and 2 lie on the fore-and-aft axis of the aircraft. Theoretical details are given.

The pattern tape bears several patterns. In one embodiment strips 2, equal in number to the number of read-outs are provided across a board or drum. Each is provided with a peg 7 for connection to the read out, and a series of plugs 6 set in the base of L-shaped arms 3. Connectors 4 extending transversely to the strips are pivotally mounted in the arms. The connectors are provided with knives 19 which contact the plugs 6 and are connected to terminals 21 for connection to the electromagnets. Spring strips 17 hold the connectors in an operative position. The connectors can be pivoted to an inoperative position and moved longitudinally. The number of plugs 6 and corresponding terminals 21 along a strip equals the number of pattern repeats along the machine width. In an alternative embodiment, Fig. 4, rows of contact plates 103 are joined transversely below the board by strips. A slider member having connections to the electromagnets is movable along guides 108 and lockable in set positions determined by a rack 105. Pattern tapes for the machine includes information for several patterns. An endless pattern tape for e.g. three patterns I.

Abstract: 1288940 Semi-conductor devices SONY CORP 3 Dec 1969 [5 Dec 1968] 59075/69 Addition to 1287134 Heading H1K In a semi-conductor integrated circuit the individual elements are formed in single crystal regions which are isolated from one another by walls 204 of polycrystalline material whose impurity concentration is less than that which gives the polycrystalline and single crystal material equal resistivities. Such a circuit is fabricated by depositing seeding sites 20 for development of polycrystalline silicon on the surface of a silicon substrate by vapour depositing amorphous solids or polycrystalline materials or by disturbing the crystal lattice at these sites. Subsequently a vapour growth silicon layer 203 is grown on the substrate to form a single crystal layer except over the seeding sites where it is polycrystalline. ,Such polycrystalline walls may have very small thicknesses such as 5 to 20 microns, thus allowing close packing of the circuit elements. Finally a polycrystalline silicon layer 205 is formed on the opposite side of layer 203 from the substrate, and the latter is removed. Circuit elements are then formed in the single crystal regions 206. Buried high conductivity regions can be formed during the above process, Fig. 4 (not shown), by diffusing impurity into the required regions from the free surface of layer 203 before the formation of layer 205, so that when the substrate is removed these doped regions are at the bottom of the single crystal regions.

Abstract: 1289095 Holography AGFA-GEVAERT N V 25 Sept 1969 [2 Oct 1968] 46847/68 Heading G2J A hologram is recorded in a medium 10 in optical contact with one face 11 of a prism, a reference beam 14 and an object beam 16 each entering the prism through different faces 12, 13, which faces are also different from that in contact with medium 10. Preferably the reference beam is totally internally reflected on at least one prismair interface, e.g. the face 13 before reaching the recording medium 10. The reference beam falls on the recording medium 10 at an angle of incidence greater than the critical angle of the medium/ air interface. To prevent interference by total internal reflection the medium contains absorbing dyes which are bleached out when the hologram is developed. In another embodiment to prevent aberration a second prism 22 is located in the object beam path, whereby the object beam enters prism 22 through a face parallel to the recording layer and the exit face is parallel to the entry face of the first prism. If desired the recording medium 20 may be in contact with the prism through a liquid, gaseous or adhesive interlayer 21. The prisms may be any desired shape. In reconstructing an image a reconstruction beam is used which follows the same path relative to the hologram as the reference beam and so forms a vertical image, the reconstruction beam being totally internally reflected as shown by broken lines.
