Patent GB-1010020-A (GB)
Title: Zirconia sols
IPC: C04B35/46
Filed: 1964-08-13
Abstract: A hydrosol of stabilized zirconia particles wherein the particles of the sol consist of zirconia and a stabilizing oxide which is one or more of scandia, yttria, or oxide of rare earth with atomic numbers 62 to 71 inclusive, the proportion of stabilizing oxide being such that it forms with the zirconia a single solid solution phase having a cubic or tetragonal structure with a monoclinic-tetragonal transformation temperature below 10 DEG  C.  Yttria may be present in quantities up to 55 mole per cent and the other oxides up to 50 mole per cent of the total zirconia and stabilizing oxide.  The sol may be prepared by a process comprising (1) adding a base, e.g. ammonia to an aqueous solution of a zirconium salt and the stabilizing element salt to co-precipitate zirconia and the stabilizing oxide, (2) separating the precipitate and removing electrolytes, (3) slurrying the precipitate in de-ionized water at a concentration of 10-80 gm./1/. (4) adjusting pH of slurry to between 3.5 and 7, e.g. with a cation exchange resin in the hydrogen form or a mono-basic acid, and (5) peptizing the slurry by heating at 60 DEG  to 120 DEG  C. for at least half an hour. Another preparation of the sol involves auto-claving together a reactive zirconia and stabilizing oxide sol for a time and temperature sufficient to cause interaction between the sols, e.g. 100 DEG  to 150 DEG  C. for 1 to 10 hours. Colloidal particles of stabilized zirconia are obtained by separating the particles from the sol and heating the separated particles at above 350 DEG  C. for 1 to 10 hours.

A metal strip 1 is severed along the lines 2 .. 5, Fig. 1, to form spokes 10 and portions 7 are removed from the edge 17 to form apertured securing lugs 6. The spokes and lugs may then be bent in opposite directions at right-angles to the portion 16 of the strip and the latter bent to circular shape, as shown in Fig. 3, to form the wheel hub, or alternatively the strip shown in Fig. 1 may be bent to a cylindrical shape, the ends welded and the spokes and lugs then bent in opposite directions. The spokes may all be bent to the same angle and secured to the middle 13 of a wheel rim 11, as shown in Fig. 5, or alternate spokes may be of different lengths and bent to different angles so as to be secured to the outer edges 11, 14 of the rim or to one outer edge and the middle. In an alternative method a strip 1, Fig. 8, is severed along the undulating line 2 to form two wheels simultaneously, the alternate spokes 15 of each wheel being shortened if necessary. The strip shown in Fig. 1 may be profiled, as by.rolling, to a cross section which reduces in thickness from the edge 17, and the strip shown in Fig. 8 may taper from each edge towards the middle. The spokes may be pressed to a curved section before the strip is bent.

Binary data words are provided with a number of parity bits by feeding each word in parallel to a number of stages of a circulating register, further stages being reserved for the parity bits, shifting the data and counting the 1's circulating through a given stage, and entering into that stage the appropriate parity bit as a " blank space " reaches it. As shown, the register CR consists of 72 stages, a 1 in stage 72 enabling a pulse to be applied to a parity bit counting flip-flop 220 after each shift. Four timing pulses C0-C3 occur in each shift period, these pulses are used for shift in CR (line 88 at C3 time), counting of the number of shift periods in cascade counter 165-172 (C0 time), insertion of parity bits in appropriate shift periods (selected by " and " gates connected to outputs of 165-172 and feeding terminal 226 and " or " gate 232) (C1 time), and " start of operation" (C2 time at 174 to switch 173). Data is entered into CR, from one of two sources selected by line 86 or 89, over lines 92, 96 and a number of parity digits are used, one following each of a number of groups of data bits, the parity bit counter being reset via " or " gate 164 at the start, and after each parity bit insertion. Odd parity is normally used, but gate 223 allows even parity to be used for the single group selected by input 226.

[Also in Group XL (b)] The images of the template and the workpiece in a copying machine are projected simultaneously on to the photo-cathode of a television camera tube, so that any lack of register produces an area having a distinct light intensity or hue, which produces pulse signals when the tube is scanned. The images are combined either by means of a partially reflecting mirror, Fig. 1 (not shown, or a prism, Fig. 4 (not shown). It is stated that the two objects are illuminated so as to contrast with their backgrounds. At the same time the light intensity due to the two images in coincidence is made equal to the light intensity due to images of the two backgrounds which are also being projected on to the photocathode. It is suggested that object and background could be in contrasting colours. The electrical output of the camera tube may either be displayed on a television receiver or used to control the position of the grinding wheel of a copying machine in which a single line is scanned at the working point and the grinding wheel is advanced or retracted in an undisclosed way according to the presence or absence of a pulse. It is stated that the control signals for the whole process can first be stored and then read out.
