Abstract: 633,948. Knitting-machines. STIBBE & CO., Ltd., G., STIBBE, E. V., and BROWN, A.M. Feb. 26, 1947, No. 5587. [Class 74 (ii)] A circular machine having nib jacks for producing shaped areas of spliced fabric as described in Specifications 210,046, [Class 74 (ii)], 417,472 and 500,435, is provided with weltturning mechanism and means for selectively operating the nib jacks to cause the corresponding needles to operate with the welt instruments. The welt-turning mechanism comprises a dial having welt instruments 5 therein and a dial cam system operative upon the instruments 5. The series of nib jacks comprises two or more central jacks 3 with long butts interspersed with short butt jacks, and jacks 1 with short butts interspersed with jacks 2 having medium butts. Cams 6, 7, 11 are provided for operating the jacks, the cams 6, 11 being movable radially under pattern control; and in addition to the usual knitting cams F, radially movable cams 8, 9 are provided for action upon the needle butts 10. In forming a welt, and with the jack cams 6, 11 in their operative position to obtain a 1Î1 selection of needles, the cam 8 is moved to its innermost position at the commencement of knitting, and after knitting three-quarters of a course the cam 9 is moved inwards to its intermediate position. At the completion of the first course, cam 8 is retracted to its intermediate position, and after three-quarters of the second course has been knitted, the cam 9 is completely retracted. On completing the second course, cam 8 is again moved to its innermost position. During the knitting of the third course, alternate needles are at a low idle position and the welt instruments 5 are in action. At the termination of the fourth course the cam 8 is retracted to its intermediate position, and after a quarter of the fifth course has been knitted, the cam 8 is fully retracted and the cam 9 is moved to its innermost position and the jack cam 6 is withdrawn so that all the needles 4 knit the welt. To complete the welt by returning the loops held by the welt instruments to the needles, the cam 6 is moved into operative position and the cam 9 remains in its innermost position. The butts of the intermediate needles are lowered by the cam 8 to a position beneath the fully advanced welt instruments 5 and are raised by the cam 9 to penetrate the loops of the instruments 5, Fig. 11, the instruments being thereafter fully retracted to leave the loops on the needles.

Title: Titanium pigments
Inventor: MURLEY RICHARD DUNCAN
IPC: C09C1/36
Filed: 1962-02-21
Abstract: Titanium phosphate, believed to be the pyrophosphate TiP2O7, is prepared by simultaneously introducing a titanium tetrahalide and phosphoric acid or soluble salt of phosphoric acid, e.g. NH4H2PO4, into an aqueous liquid; recovering the titanium phosphate precipitate thus formed and then heating the precipitate. The titanium tetrahalide is preferably the tetrachloride, the pH of the aqueous liquid is preferably below 7, the precipitation being performed in the presence of excess phosphoric acid or soluble salt thereof, e.g. 1-50 gm./litre estimated as H3PO4.  The titanium tetrahalide, the phosphoric acid, and the salt of phosphoric acid may be introduced as aqueous solutions, and are preferably introduced into the aqueous liquid at a rate such that no local excess of titanium tetrahalide occurs in the solution. The aqueous solution may be heated preferably to its b.pt. during the addition of the reactants or the reactants may be added and the solution subsequently heated.  The halide solution used has a concentration of preferably 25-220 gms./litre (estimated as TiO2) and the precipitate produced may before separation be mixed with phosphoric acid or an aqueous solution of a salt thereof and boiled.  The ppt. is then separated, dried and ground and heated at a temperature in the range 750 DEG  to 1100 DEG C. and subsequently milled to produce a mean crystal size of 0.1 to 2 microns.  After recovery but before heating, a compound which reduces the temperature to which the titanium phosphate must be heated to form a pigment may be added to the titanium phosphate precipitate. The preferred compound is potassium phosphate and it is added in an amount sufficient to give a concentration before heating (estimated as potassium) of at least 0.05% by weight, preferably 0.1% to 2% by weight.
