Title: Improvements in and relating to titanium pigments
IPC: C01G23/08
Filed: 1939-06-21
Abstract: 530,877. Titanium pigments; titanium dioxide. DU PONT DE NEMOURS & CO., E. I. June 21, 1939, No. 18121. Convention date, June 22, 1938. [Classes 1 (iii) and 95] In a process of the production of titanium dioxide pigments, a titanium-oxygen compound is calcined to develop pigment properties in the presence of a substance which will inhibit or retard the conversion of the titanium compound into the rutile crystalline form, and the product so obtained is recalcined, in the absence of such a substance, to change the crystalline form of the titanium dioxide to the rutile modification. Suitable inhibiting or retarding substances are alkali-metal compounds such as potassium carbonate, potassium sulphate, sodium sulphate and sodium sulphide, the amount used not exceeding about 2 per cent. by weight of the pigment and the amount of the compound present is reduced below 0.1 per cent. prior to the second calcination step. Temperatures of 800-1100‹C. are mentioned, the second calcination being conducted at a higher temperature than the first. The process may be applied to the production of pigments consisting of titanium dioxide, and also to pigments containing extenders such as alkaline earth metal sulphates, silica and magnesium silicate. According to Examples : (1) hydrated titanium oxide is calcined with 0.5 per cent. of potassium sulphate at 985‹C. The product is dispersed in water with 0.18 per cent. of sodium hydroxide, and ground. The slurry is coagulated with 0.5 per cent of magnesium sulphate, neutralized with sulphuric acid, filtered, dried, pulverized and recalcined at 1000‹C. for several hours to transform it to the rutile modification ; (2) hydrated titanium oxide is calcined with 0.5 per cent. of potassium sulphate at 975‹C. The product is leached with water until the content of soluble salts is well below 0.1 per cent. and is then recalcined ; (3) hydrated titanium oxide, obtained by the hydrolysis of titanium sulphate solution, is calcined with 0.75 per cent. of potassium carbonate at 950‹C. The product is dispersed in water, wet ground and elutriated. The resultant dispersion is coagulated with sulphuric acid and filtered. The filter cake is dried, re-calcined at 1025‹C., and ground.

Abstract: 1371997 Semi-conductor devices; printed circuits RCA CORPORATION 21 April 1972 [26 April 1971] 18575/72 Headings H1K and H1R An integrated circuit package structure comprises a terminal member having a glass ceramic or other insulant substrate carrying a metallized pattern of conductors 16 deposited through a mask or by silk screening, to which plural external leads connecting to external circuitry are, e.g., brazed. An interconnection assembly 20 has a surface 21 of an insulant coating 23 of a semi-conductor body 24 which carries cantilevered beam leads 22 whose wider spaced outer ends are coupled to conductors 16; and the package is closed by a ceramic cap 25 recessed to accommodate the central element and a semi-conductor chip 27 recessed in substrate 12 has plural peripheral beam leads 28 correspondingly attached to the inner ends of divergent beam leads 22, similarly spaced. The body of the assembly is fabricated of s/c material similarly to chips 27. In manufacture, an e.g. Si wafer is surface oxidized and coated with Ti, Pt or Pa, and Au by evaporation, and etched, with a selective solvent e.g. aqua regia over a photo-resist defining the lead pattern, so that Ti layer is exposed in the areas not covered by photoresist and all three layers are left in the covered areas (Fig. 7, not shown). The outer ends of the leads on the wafer are plated up over a masking coating in a gold electrolytic bath; the Ti layer being the anode and further gold being applied to layer 40. After this the underside of the wafer is etched or ground down and covered with resistant coating, after which it is etched through (Fig. 9, not shown) for separation into plural assemblies 20 with cantilever beam leads 22 which are then bonded to beam leads 28 of chips 27 (Fig. 10, not shown). After inversion, the assembly is bonded to conductors 16 and capped at 25. In the alternative, no ceramic or like substrate is employed, but the external conductors are extended directly for bonding to beam leads 22, and the entire assembly is potted in plastics.

[Classes 49 and 81 (i)] [Also in Groups III and XIII] Refers to Specifications 513,466 and 513,562 and comprises an improved method and apparatus for desiccating biological substances such as sera, guinea-pig compliment, vaccines, breast milk &c. by degassing, freezing or self-freezing and dehydration by evaporation in vacuo through the agency of a regenerable chemical desiccant. The specimens are placed in glass containers 53, Figs. 1 and 3, each connected to one of two exhaust manifolds 58, 59, via a tube 51 and a nozzle 86 controlled by a valve 52. A series of containers is arranged on each side and may be supported by perforated screens 91 on adjustable trays 54 whereby a freezing-mixture may be applied prior to desiccating. Desiccation is effected by operating the exhaust pump 22, air and water vapour passing through perforated trays charged with desiccant and so arranged that smaller trays 32 alternate with larger ones 34 which are provided with circular, central air channels 48. In a modification the trays are disposed vertically. If the specimens are to be degassed before drying, the valves 37, 38 of the pump are so regulated that frothing just occurs. Some specimens may be frozen, by exhaustion, without the use of a freezing-mixture. When exhausted, the desiccant is regenerated by air blown through a lagged heater 24 and valve 60, the pump 22 being shut off and the air-tight cover 26 removed. After the specimens are completely desiccated, the necks of the containers are sealed off by a flame after admitting dry air through a drier 117, furnished with a hollow needle 110 which is pushed through the rubber connector 88. The containers may be formed with a reduced neck closed by a recessed rubber stopper through which a hollow needle may be inserted to supply liquid for restoring the specimens to their original state.
