Abstract: 311,950. Morton, D. May 29, 1928. Variable-speed gearing comprises a series arrangement of two-speed epicyclic gears in which change from speed reduction to solid drive is effected by an automatic centrifugal clutch which does not transmit the load, the clutches becoming operative in succession. In Fig. 1, shaft 1 drives sleeve 21 through one of these gear units. Stepped planets 7, 8 carried by a drum 10 mesh with sun gears 6, 20 on the shaft 1 and sleeve 21 respectively. The drum 10 being kept from turning backwards by a roller detent 12, Fig. 3, reduced driving takes place through train 6, 7, 8, 20. When, owing to reduced load, the sleeve 21 accelerates, clutch shoes 29 are moved out by centrifugal force so that the drum 10 is drawn round at the same speed as the whole train. The arcuate shoes 29 are supported upon pins 28 which slide outwards in slots 27 against the pull of springs 30. The slots 27, which are formed in the arms of a spider 26 fast on sleeve 21, are inclined to increase the grip of the clutch after engagement. The second train 7<1>, 8<1>, 10<1>, &c. is similar to the first, the clutch being tuned for a different speed of engagement. Forward and reversed driving are obtained by moving a combined gear and clutch 53 to right and left respectively of Fig. 1.

Abstract: 562,617. Titanium dioxides and oxyhalides.. BRITISH TITAN PRODUCTS CO., Ltd, (Du Pont de Nemours & Co., E. I.). Nov. 11, 1942, No, 15970. [Class 1 (iii)] Titanium dioxide is precipitated by hydrolysiug a titanium salt solution to which has been added a nucleating material containing a titanium oxyhalide, preferably titanium oxychloride. The nucleating material may be prepared by evaporation of a titanium chloride solution containing more than 300 g. TiO2 per litre, and hydrochloric acid equivalent to about 3 or 4 mols HC1 per mol TiO2, by passing a current of air or other inert gas over it at an elevated temperature, e.g. 50-85‹ C. Alternatively, anhydrous TiCl4 may be added to concentrated hydrochloric acid until a substantially dry powder is obtained which is further dried at 50-70‹ C. preferably in a current of air. The preferred dry seeding material has the composition Ti(OH)3Cl.5.H2O although the atomic ratio of Cl : Ti may vary from 0.8- 1.2 : 1. according to the conditions of preparation. Oxybromides and oxyiodides of like composition may also be used, prepared by evaporating or drying the corresponding titanium salt solution. The material is preferably added to 2-5 times its weight of cold or hot water to form a colloidal solution, but may be used dry or in other diluents, for example dilute titanium solutions such as wash waters from the process. The colloidal solution is generally added to the titanium salt solution to be hydrolysed immediately prior to heating and in an amount of about 0.3-5, normally 0.75-2 per cent by weight thereof. Titanium chloride or nitrate solutions containing about 90-120 g/l. TiO2 may be treated to give a rutile pigment but other salts such as the sulphate which gives anatase may be employed at concentrations of about 150-210 g./l. In examples : (1) TiCl4 is dissolved in water until the solution contains 390 g./l. TiO2 and 643 g/l. HC1. This is evaporated to dryness in air at 60‹ C. and dissolved in 3 times its weight of water. The hydrolysis of a TiCl4 solution at 95‹ C. is described. The product is calcined at 800‹ C. to give a pigment; (2) TiCl4 is added to hydrochloric acid and the dry powder obtained heated at 70‹ C. for 1 hour in an air current. It is added to 4 times its weight of water and the solution used for seeding a TiC14 solution which is hydrolysed at above 90‹ C. The titanium oxide is calcined at 975‹ C. to form a pigment.
