Title: Improvements relating to the growing of p-type dihydrogen phosphate crystals
IPC: C30B7/00
Filed: 1954-10-11
Abstract: P - type dihydrogen phosphate crystals, particularly primary ammonium phosphate crystals, are grown by cooling from solutions which contain the triphosphate ion (P3O10 - - - - -) or the trimetaphosphate ion (P3O9 - - -) in amounts of from 0.13 to 0.35 grams per litre of solution.  The ions become absorbed into the crystal lattice and effectively inhibit the growth of the crystals in the X and Y directions, enabling more Z cut crystals to be obtained from the resulting crystals.  Instead of the specified ions other ions such as the hexametaphosphate which break down to the triphosphate ion may be added in appropriate concentration.  Iron may also be present in the growing solution, reducing the polyphosphate ion concentration required.  Thus 80 parts iron and 200 parts triphosphate ion may be present per litre of solution.  Chromium may also be present. The crystal may be grown by the general process described in Specification 653,733.

Title: Improvements relating to the loading of natural silk
IPC: D06M11/20
Filed: 1930-10-03
Abstract: The process of the parent Specification is modified in that the silk is further treated with a dilute alkaline solution of natural resins or of resin-like condensation products.  Such natural or artificial resins may be present in the alkaline phosphate bath or in the silicate bath or may be applied in a separate bath at any stage after the alkaline phosphate bath.  The pH value of the bath containing the loading metal salt is preferably maintained constant as described in Specification 366,941.  In an example the debasted silk is treated for 10 mins. in a first bath, at 42 DEG  C., containing tin tetrachloride, monosodium phosphate, and magnesium chloride, and after squeezing or subjecting to suction is passed into a second bath at 60 DEG  C. containing ammoniacal disodium phosphate; it is then rinsed, again squeezed or subjected to suction and treatment in the first and second baths is repeated as often as desired; it is then passed through a dilute solution of water-glass and through a weak soap bath, and is treated for about 10 mins. in an ammoniacal solution at 50-60 DEG  C. containing a urea formaldehyde condensation product or in an alkaline solution containing Dammara resin emulsified in olive oil or a mineral oil, and is finally dried.  To avoid the formation of common salt in the loading operation the sodium phosphates may be replaced by magnesium phosphates.  The urea-formaldehyde condensation product is prepared by dissolving 2000 g. urea in 5000 cc. of 40 per cent formaldehyde, adding concentrated ammonia until the solution is alkaline to litmus, allowing to stand at room temperature for 12 hours, stirring vigorously to cause the condensation product to solidify to a stiff paste, and allowing this to stand in an open vessel for 1 or 2 days with frequent stirring. The various vessels used in the loading process may be of enamelled or glazed iron, acid-proof metal alloys, earthenware, porcelain, or artificial resins, or may be lined with any of these.  The conveyer cloth may be of porous rubber or of rubber-covered wire or of fabric, especially acid-proof fabric, made, e.g. of acid-proof wire, wool, silk, or nitrated cotton, coated with rubber, asphalt or varnish; rubber-coated waste silk or Chappe silk is particularly suitable. The rollers for squeezing the silk may be of acid-resistant hard rubber, hard stone, porcelain or clay, and acid-proof earthenware pumps may be used for circulating the first treatment liquor.
