Title: Improvements relating to the manufacture of titanium dioxide
IPC: C01G23/07
Filed: 1930-07-07
Abstract: Titanium dioxide in a form utilizable directly as a pigment is obtained by bringing vaporized titanium tetrachloride into contact with steam preheated to a temperature of 300-400 DEG  C. or other temperature below 500 DEG  C. in a reaction space maintained at such temperature.  The titanium tetrachloride vapour may also be preheated to the temperature at which reaction is effected.  In carrying out the process 1 litre of a mixture of air and steam in substantially equal parts by volume and 0,1 litres of a mixture of titanium tetrachloride vapour and air also in substantially equal parts by volume may be introduced per minute per litre of reaction space, the reaction being effected in an externally heated vessel with downward travel of the reaction components. The titanium dioxide is collected at 200-400 DEG  C. to prevent absorption of hydrochloric acid, and the product may be calcined, if desired.

Polymers or copolymers may be prepared from styrene alone or with a -methyl styrene, ar-monochlorostyrene, ar-ethylvinyl benzene, maleic anhydride or methyl methacrylate, from ethyl acrylate and methyl methacrylate, and from styrene, ar chlorostyrene and a -methyl styrene or methyl methacrylate.  If desired a major portion of the product may be recycled and a minor portion withdrawn.  In copolymer preparation, the monomers, in the corresponding relative proportions are polymerized and the unreacted monomers recycled until the system is in balance and the composition of the withdrawn copolymer corresponds to the ratio of the monomers in the feed.  Alternatively, the feed mixture may be a partially polymerized mixture corresponding to the composition of the product.  Suitable apparatus may include as a polymerization chamber a vessel, Fig. 1, or a zone, Figs. 2, 3, 4, through which the mixture may be pumped or extruded.  Inlets 1, 2 (2 being used for a second monomer in copolymer preparation) lead to the zones 4, 15 and an outlet 9 to a devolatalizer 10, from which monomer vapour is recycled to the inlet.  A recycling circuit 6, 8, Figs. 2, 3, and 15a, Fig. 4, may be used to return polymerization mixture to the inlet.  In a modification where polymers having different predetermined molecular weights in predetermined relative proportions are required a pair of zones 4, 4a, Fig. 3, in parallel may be used and the products blended.  Polymers of uniform molecular weight and predetermined composition are obtained, suitable for moulding. Specifications 660,940 and U.S.A. Specifications 2,100,900 and 2,496,384 are referred to.

Abstract: 1491405 Preparing vodka from whey NAUCHNO-PROIZVODSTVEN OBJEDINE MASLODEL I SYRODEL PROMYSHLEN UGLICH 20 May 1976 20917/76 Heading C6E A process for the production of vodka involves the steps of fermenting pasteurized whey, e.g. cheese or curds whey (acidity 16-18‹T), at a temperature of 28-30‹C for 48-72 hours using 15-20 wt. per cent, based on the weight of the whey, of a milk-yeast leaven containing yeast of the genus Candida and/or genus Torulopsis to obtain a mash of the fermented whey, recovering ethanol from the resulting mash e.g. by fractional distillation, rectifying the ethanol, purifying the rectified ethanol by removal of the products of proteolysis therefrom and diluting the resulting purified ethanol with whey containing not more than 0À05 wt. per cent of proteinaceous substances whereby a final product (vodka) containing 30-45 wt. per cent of ethanol is obtained. The vodka product has a clearly pronounced "soft" taste, a specific pleasant smell and a lemon colour with a greenish tint. The leaven preferably includes one (or all) of the following strains of yeast: Candida pseudo-tropicalis var. lactosa 85 and Torulopsis sphaerica strains SK and 11A. According to Example 4, a mixture of the three strains is employed in the weight ratios 50:90:50. Although the purification step may be effected by any conventional method, such as gel filtration, reverse osmosis or electrodialysis, the preferred procedure is to treat the ethanol with 5-10% by weight of skimmed milk, to maintain the resulting mixture at a temperature of 20-30‹C for 20-60 minutes to cause coagulation of proteins therein and then to remove the coagulated proteins.

Abstract: 951,774. Calculating apparatus; cash registers. SVENSKA DATAREGISTER A. B. June 17, 1960 [July 6, 1959], No. 21473/60. Headings G4A, G4C and G4T. An electric store is interconnected with the differential mechanism of a calculating machine  such a manner that digital data can be sent from one to the other and vice-versa. An input device 100 has five manually operable binary keys whereby entries 1-31 may be made. Entries 1-9 have their decimal equivalents, 15 is used for correction, 16 is zero, 17-25 represent appropriate lines of goods, and 28-31 represent received, credit, sub-total and total, respectively. As each decimal digit of the first item is entered via device 100 into input register 102, so control circuit 122 causes it to be moved to first shift register 104, and then as appropriate to shift registers 106....108. An entry in the range 17-25 is directed by input register 102 automatically to line of goods register 116. The control circuit then causes the entries in the shift registers 104....108 to be transferred in complementary form to output registers 110....114 and automatically sets mode of control register 118 for a listing operation. Control circuit 122 also operates release mechanism in the cash register so as to operate the slide differential mechanism. At each step of the various slides a pulse is returned to the related register. Each register comprises a binary cascade counter using transistor flip-flops and each pulse advances the appropriate counter. As each counter reaches reset position it returns a pulse to operate stop mechanism whereby the associated slide is halted. The transaction slides (line of goods and mode of operation) are operated before the amount slides. Repeated item. If the next item is identical with the first it is sufficient to re-operate the line of goods key as the original item is still standing in the shift registers 104....108. The operation of any other key clears these registers. Total or sub-total. An entry in the range "26-31" causes the control circuit 122 to clear the registers 110-118 and set up the appropriate mode of operation in register 118, following which the cash register performs the appropriate totalling operation. The amount slides are set according to the total and send impulses to the associated registers 110....114 which are therefore set to the true amount in the totalizer. This amount is then transferred by the control circuit to parallel output recorder 126. A record reader 124 provides a parallel input from card or tape to the read-out and control registers.
