Title: Process for the manufacture of a Rutile Pigment by Oxidation of Titanium Tetrachloride
Inventor: KULLING ACHIM
IPC: C01G23/07
Filed: 1966-12-05
Abstract: 1,155,558. Rutile TiO 2 . TITAN G.m.b.H. 5 Dec., 1966 [11 Dec., 1965[, No. 54411/66. Heading C1N. Rutile TiO 2  pigment is produced by reacting gaseous TiCl 4  with 0 2  in a reaction chamber, and cooling the reaction products with cold inert gas in an immediately adjacent mixing chamber, the cold gas being introduced into the end remote from the reaction chamber and in countercurrent to the reaction products. Initial contact with the cold gas, which may enter at room temperature, and by then is at 800- 1250‹ C., prevents further particle growth but allows rutilization to continue. The cold gas may be air, N 2 , C0 2 , C1 2 , or cooled product gases freed from TiO 2 . It may be introduced at one or several points, e.g. at 400 m.<SP>3</SP> per 500 kg. TiCI 4 . Preferably, the reactants are introduced downwards, the cold gas upwards, and the gas mixture withdrawn either through a pipe concentric within the cold gas inlet pipe (Fig. 4) or sideways from the middle of the mixing chamber (Figs. 1-3), coarse TiO 2  being removed from the bottom. The cold gas inlet may have a conical distributer (Fig. 2) or guide vanes which impart spiral flow (Fig. 3). The mixing chamber may be cylindrical or conical, and of circular or square cross-section. In examples, TiCI 4  containing AlCl 3  at 350‹ C., O 2  at 250‹ C., and CO (auxiliary) at room temperature are used, and the products withdrawn at 730‹ C. The TiO 2  produced contains less than 1 % anatase.

Title: Apparatus for Maintaining Tension in a Flexible Element.
IPC: B66C13/12
Filed: 1966-12-06
Abstract: 1,173,581. Spring drum apparatus. AEROMOTIVE MFG. CO. 6 Dec., 1966 [6 Dec., 1965], No. 54616/66. Heading B8B. An apparatus for maintaining tension in a flexible conductor 28 extending between fixed and moving junction boxes comprises a carriage 36 movable along a path parallel to that of the movable junction box, a cylindrical casing 105 mounted on the carriage for rotation relative thereto, and supporting a drum 106 around which the conductor is wrapped, and sprockets 116, 117 for rotating the casing 105 in response to movement of the carriage 36 along the path. A pair of series connected spiral springs 122, 123 coupled between the carriage and the casing oppose rotation of the latter in one rotational direction and urge rotation of the casing in the other rotational direction. The carriage 36 is supported by pairs of rollers 84, 85 engaging two tracks 67, 68 running the length of said path. A pair of chains 138, 148 extending the length of the tracks 67, 68 and anchored at both ends, pass over the sprockets 116, 117 and under another pair of sprockets mounted on the carriage. As the carriage 36 is pulled in one direction by the conductor 28, the chains 138, 148 cause sprockets 116, 117 to rotate and wind up the springs 122, 123. Upon release of this conductor pull, the springs drive the sprockets against the chains to move the carriage thereby taking up slack in the conductor. The initial spring tension is adjustable via helical wheel 91. The flanged drum 160 around which the conductor 28 is wrapped, is freely rotatably mounted via rollers 151, 152 supported on the casing 105. Wires 163, 164 are laid along the path of the conductor 28 to relieve the excessive tension in the latter. A channel 59 supports the portion of the conductor extending between the carrier 36 and the fixed junction box. The drum 160 may be provided with partition flanged to accommodate a plurality of flexible elements. In a further embodiment, Fig. 12 (not shown), the chain and sprocket device is replaced by a rack and pinion device. In another embodiment, Fig. 13 (not shown), only one chain and sprocket mechanism is used to drive the carrier and this is positioned in a recess intermediate the length of the cylindrical casing. In another embodiment, Figs. 22, 23, 24 (not shown), the carrier is mounted from one side by V-grooved rollers engaging V-shaped rails. The chain and sprocket drive mechanism is positioned between the two vertically spaced rails. The spring motor of any of the aforesaid embodiments may be replaced by an electric, hydraulic or pneumatic motor.

Filed: 1970-11-19
Abstract: 1315528 Data storage INTERNATIONAL BUSINESS MACHINES CORP 19 Nov 1970 [31 Dec 1969] 54934/70 Heading G4C A data memory has a matrix of memory elements in each of which data can be circulated under electronic control responsive to a selectable one of two clocking rates, addressing being by selecting a set of the memory elements in response to a first part of the address and by comparison of the current position of the data in each element of the set with a second part of the address. A plurality of memory cards each have a 2- dimensional array of recirculating shift registers using IGFETs and capacitive storage. On each card, 4 Î 4 modules are provided, each consisting of 2 x 2 chips, each of which holds 2 Î 2 shift registers. A word position consists of a bit position in each card, there being 128 cards for data, 9 for error-correction circuits, 4 spare and 4 for control. A word is accessed by decoding X and Y co-ordinates forming part of the address, to select the relevant shift register in each card, the selected shift registers then being shifted at high speed with incrementing of a specific address counter (specifying the recirculation position of the selected registers) until this counter equals the rest of the address, indicating that the required word is at the read-write position. A series of words may be read or written into. After reading or writing is over, the selected shift registers are shifted at high speed with incrementing of the specific address counter until this equals a general address counter (specifying the recirculation position of the non-selected registers). Every 128 Ásecs., all the registers are shifted by one bit position at low speed for regeneration, with incrementing of both counters, access to the registers being inhibited during this. Conventional features described include communication with a computer I/O channel, and error features including indication of a count of correctable errors exceeding a threshold, of accessing outside preset address boundaries (storage protection), and of a write attempt when a write inhibit command is in force.

Abstract: 1,137,290. Amylose-paper laminate. A. E. STALEY MFG. Co. 13 Dec., 1966 [12 Jan., 1966], No. 55680/66. Heading B5N. An amylose film is bonded to a cellulosic substrate by wetting one or both of the contacting surfaces with water prior to bonding, and then applying pressure. The amylose film may be preformed, or may be formed by extrusion immediately prior to bonding, in which ease less pressure is needed to form a strong bond. The cellulosic material is preferably paper, e.g. kraft paper. Bonding is suitably effected between nip rolls, one of which may be heated (for bonding a preformed film) or chilled (for bonding a freshly extruded film) and the other of which may be resilient. The water is suitably introduced between the layers as they reach the rolls in an amount such that a slight excess is forced out by the rolls. The rolls may have a speed greater than the speed of extrusion, so that the amylose film becomes stretched and oriented. The amylose used is preferably unsubstituted. It may contain a polymeric plasticizer, e.g. polyvinyl alcohol and, less preferably, a polyhydric alcohol or aminoalcohol plasticizer.

Title: Methods and machines for the production of shped wooden members  each of which has a rabbet
IPC: B27M3/08
Filed: 1970-11-24
Abstract: 1336859 Sawing and splitting wood A E NORMAND 24 Nov 1970 [24 Nov 1969 10 Nov 1970] 55831/70 Heading B5L A method of dividing a length of wood 1, Fig. 2, into two members which are subsequently to be shaped to have a rabbet and an adjoining projecting portion, e.g. to form door frame members 7, 8, comprises making two cuts 9, 9 1  in the longitudinal direction of the length of wood in such a way that the cuts produce shaped edge portions on the two members which approximate to the final shaping. The cuts are offset and the weakened portion between them may be divided by splitting or by an oblique cut to separate the two members. In a machine described for performing the method, Fig. 7, a length of wood is advanced by rollers over a table section 14 1  and a longitudinal guide groove is formed in its lower face by a circular saw or mill 26. The groove is engaged by a guide member 27 as the wood passes over a table section 14 2  to a pair of circular saws 29 and 30, Fig. 6, which form partial cuts longitudinally of the wood. The wood is then guided by a member 27 1 , Fig. 7, over a table section 14 3  to a table section 14 4  having on its upper surface a tapered separating blade 27 2 . This blade engages in one of the cuts formed by the saws 29, 30 and splits the narrow piece of wood between the cuts formed by these saws so as to produce two shaped members from the length of wood. Each of the tools 26, 29, 30 is carried on a turret for pivoting about an axis, e.g. 26 2  so that the cuts formed by the tools may be inclined to the surfaces of the length of wood being cut. The guide members 27, 27 1  may be inclined correspondingly. The turret for each tool is also adjustable horizontally and vertically to vary the position and depth of the cut made. In alternative constructions the table sections 14 1 -14 4  may be above the wood or inclined. (For Figure see next page.)

Abstract: 1,117,069. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORPORATION. 15 Dec., 1966 [29 Dec., 1965], No. 56105/66. Heading G4R. The average values of the co-ordinates of a plurality of points related in a predetermined manner to a line pattern are obtained. During a first scan of a fingerprint 40 by a curve follower 30 (Fig. 2A), the X and Y coordinates of successive points on the ridges of the fingerprint are obtained as continuous waveforms (though digitization is possible as an alternative) and used by differentiators 46, 48 and divider 50 to calculate dY/dX. This is used by the circuitry in the top quarter of Fig. 2B to calculate the radius of curvature R, and also by sin A and cos A generators 76, 78 (tan A#dY/dX), the outputs of which are multiplied 72, 74 by R, the resulting products being added 84, 86 to X and Y respectively to give the co-ordinates X 0 , Y 0  of the centre of curvature. Whenever R is less than a preset maximum, as determined by comparator 70, X 0  and Y 0  are gated 88, 90 to respective integrators 104, 106. At the end of the scan the integrator contents, constituting the coordinates of the centre of the fingerprint, are stored at 116, 118. Two or more further scans now follow to obtain improved values for the centre co-ordinates, since the fingerprint may be multilated. Each further scan is like the first except that a further requirement for X 0 , Y 0  to be gated to the integrators 104, 106 is imposed, viz. that X and Y must be within a rectangular (or square) area centred on the centre obtained by the previous scan, the circuitry in the bottom three quarters of Fig. 2B being provided for this purpose. #X and #Y generators 134, 136 are preset with half the dimensions of the rectangle required. In the case of a square they could be combined. A circular area may be used instead, it is mentioned. The centre co-ordinates obtained in the last scan are used in recognition means. It is mentioned that tangent line intersections may be used instead of centres of curvature.
