Title: Improvements in the preparation of titanium dioxide pigments
IPC: C01G23/053
Filed: 1961-08-18
Abstract: Rutile is prepared by calcination at or above about 1000 DEG  C., of a hydrous titanium dioxide containing prior to calcination, rutile seeds, (in addition to those used in the initial hydrolysis) a water-soluble aluminium salt, a water-soluble phosphate and a basic potassium salt.  The calcination is continued until the titanium dioxide is substantially completely converted into the rutile form. Ordinarily, the calcination is effected in the presence of 1-6% rutile seeds, 0.3-2.5% of a water-soluble aluminium salt (calculated as Al2O3) 0.1-0.5% of a watersolubl phosphate (calculated as P2O5) and 0.1-1.0% of a basic potassium salt (calculated as K2O) based by weight on the titanium dioxide. However, if the ore from which the titanium sulphate solution is obtained contains phosphorus, then the addition of extra phosphorus compounds may not be required.  The seeds added before hydrolysis can be those obtained according to Example 1 of Specification 513,867, by halide hydrolysis in caustic soda and the seeds added after hydrolysis and before calcination, can be obtained by boiling washed hydrous titanium dioxide in a caustic soda solution for 4 hours, washing the precipitate, resuspending it in HCl solution and heating the suspension for 3 hours.  In Example II, the rutile seeds are obtained by treating TiCl4 solution with a solution of caustic soda, neutralizing the suspension obtained, and then washing out 75% of the soluble salts present.  The suspension thus obtained is added to titanium sulphate solution prior to hydrolysis to obtain hydrous titanium dioxide. The product is separated, washed and reslurried in water, to which is added rutile seeds as prepared in Specification 513,867, and an aluminium sulphate, mono-ammonium phosphate and potassium carbonate.  The resulting mixture is dried and calcined at or above about 1000 DEG  C.

Abstract: 1,156,301. Aircraft instruments. KAISER AEROSPACE & ELECTRONICS CORP. 5 July, 1966 [16 July, 1965], No. 30094/66. Heading B7W. [Also in Division H4] Signals which, when utilized to control the intensity of a line scanned raster or a cathoderay tube, produce a display simulating a path are generated by combining the output of a sawtooth wave generator operating at the field (vertical) rate of the raster with the output of a triangular wave generator operating at the line (horizontal) rate of the raster to derive signals which increase in duration during successive line traces, gating means being employed to gate only a small portion of the leading and trailing ends of each signal to the beam intensity control means of the display tube. The path produced in this manner is defined by marginal edges only so that other displayed information which occurs between such edges is not masked. The invention is described in connection with the production of an " integrated visual display " to an aircraft pilot of the kind disclosed in Specifications 1,117,272 and 921,528 and is concerned with the production of the signals required to produce a " ground texture," a " flight-path " and an " intercept " bearing indication. Referring to Fig. 1, the display produced comprises a " sky " portion 10, a " horizon " line 12, the vertical position of which is varied in accordance with the pitch of the aircraft, a general ground " texture " 14 which varies from a dark intensity at the line 12 to a lighter intensity at the bottom of the display and a plurality of ground texture elements 16 which emanate from line 12 and move across the ground texture 14 in a semirandom pattern towards the bottom of the display at a rate related to the speed of the aircraft, the shape of the elements being varied as they move to simulate a varying perspective view. Additionally, the display includes a flight-path 17, the position of the apex of which with respect to line 12 and to a fixed reference 18 may be varied with changes in aircraft pitch and heading and the shape of which may be curved as shown in Fig. 2 to indicate a changing course. The display also provides an indication of the " intercept " of the bearing of a beacon such as station 2 (Fig. 11) with respect to the bearing being flow to station 1, the display taking the form of a horizontal line which in respect of aircraft positions A, B, C occurs at the positions 1L shown in Figs. 12A, 12B and 12C respectively.

Abstract: The stitch and guard cams (16, 17) Figs. 1 and 4, not shown, for operating the cylinder needles of a multifeed cylinder-and-dial machine are mounted on a ring (15) forming an upper cam box for the cylinder needles.  The ring (15) is secured to a lower ring (12) capable of being slightly rotated about the cylinder so as to enable the cylinder stitch and guards at each feed to be simultaneously adjusted relative to the needle cylinder and the dial cams.  The position of the draw of the cylinder needles can therefore be adjusted relative to the position of the draw of the dial needles. The remaining cams surrounding the needle cylinder are retained in a lower cam cylinder box (7) and comprise cams influencing the butts on jacks positioned beneath the cylinder needles, the jacks being capable of being tilted by selector cams to bring their butts out of the range of the cams when desired.  The ring (12) is provided with an upstanding pin (20) which is engageable by a lever (18), Fig. 2 not shown capable of being moved to adjust the position of the ring (12).

Title: Improvements in machines for winding yarn or thread
IPC: B65H59/18
Filed: 1924-12-23
Abstract: 253,563. Kershaw, G. Dec. 23,1924. Driving-arrangements.-In machines for winding yarn or thread from a beam, warp, &c. on to a spindle, tube, &c. the delivery rollers are driven through a ratchet and pawl 18, 29 or other mechanism so that they may overrun if the rate at which yarn is being wound increases. To obviate too rapid delivery of yarn when the mechanism is started, the drive is transmitted through a spring coupling as shown in Fig. 5, or through a friction clutch as shown in Fig. 8, in which a sprocket 42 drives the rollers through a disc 46 held frictionally against the sprocket 42 by a spring 48. When the tension rollers are overrunning, a disc 443 of flannel &c. carried by a disc on the driven shaft provides frictional resistance and so acts as a brake. Specifications 2335/10 and 196,498 are referred to. Reference has been directed by the Comptroller to Specifications 109,242 and 132,854.

Fig. 1 illustrates apparatus in which fabric sheets 3 are fed along the worktable 1 of a sawing machine 2 by means of its feed dog (not shown); the leading end 4 of a sheet hangs down over the edge 10 of the table at the end of a feeding motion. The lower part of sheet 3 is clamped between a stacking rail 20 and a clamping member 30 carried on an arm 32 which oscillates under the action of fluidpressure cylinder 33; the top part of the sheet 3 is thrown over the rail 20 by means of a member 40 connected to a second cylinder 42, the cylinders being suitably controlled for the desired stacking action. In an alternative embodiment, Figs. 2 and 3 (not shown), the clamping member (80) is vertically reciprocable on a guide rod (87) to withdraw a workpiece from the sawing machine; the lower and upper parts of the workpiece are directed into their required positions over rail 20 by air blasts (62, 92) after the clamp has been released.
