In the position shown, a current initially flows through capacitor C1 and winding M which holds the contact more firmly in this position, and a smaller standing current flows through resistor r 2  and the winding S. When the current through C1 decays to a low value the current through coil S causes the contact a 1  to change over to position s. A corresponding cycle now takes place to change the contact a 1  back to its original position. To operate an external circuit B  an additional relay - may be employed, having 1 one or two windings connected in series with either or both capacitors respectively, the relay B/1 contact b 1  moving in sympathy with a 1 . A third winding M<SP>1</SP> may be included on relay A/1 to stop the relay in one position which winding may be energized from a remote source. Contacts of relay B/1 may be connected in series with the third winding when stoppage of the relay only after completing its cycle is required.

Title: Process for the working up of hydrolysis acids obtained in the production of titanium dioxide
IPC: C01B17/58
Filed: 1961-11-10
Abstract: Hydrolysis acids, obtained in the production of titanium dioxide by the sulphuric acid decomposition process, are worked up by (1) pre-concentrating the hydrolysis acids with immersion heaters, (2) adding thick sludge from the concentrated acid produced in a previous cycle, (3) filtering off the separated salts from the acid which contains less than 70% H2SO4, (4) separating again the filtrate to a H2SO4 content of 93.5-95.0%, (5) decanting the concentrated acid from the freshly separated salts, (6) returning the thick sludge to the preconcentrated salt suspension, (7) granulating the sulphuric acid-containing filter cake with the addition of roasting residue, obtained from a sulphate decomposition furnace, and (8) transforming the granules into oxides and sulphur dioxide in an oil, tar, coal, coke, and/or sulphur-heated sulphate decomposition furnace.  The hydrolysis acids may be briefly heated, preferably in the presence of titanium dioxide hydrate crystal seeds, to 140-180 DEG  C. under an appropriate pressure prior to evaporation. The heat of the exhaust gases from the immersion heater may be used for a preliminary concentration of hydrolysis acids by means of indirectly heated heat exchangers under a vacuum or by sprinkling the heat exchanger with acid under normal pressure.  An oxidizing agent, preferably nitric acid, a nitrate, a nitrite or a nitrosyl-sulphuric acid may be added to the pre-concentrated acid to convert any ferrous sulphate present to ferric, phosphoric acid or a phosphate may be added to the hydrolysis acids, prior to pre-concentration, in order to precipitate the titanium ions dissolved therein, the precipitate being separated. Ferrous sulphate heptahydrate may be added to the hydrolysis acids prior to preconcentration.  The preheating of the acids may be done with expanded steam.  Examples illustrate the process.

Untwisted yarns are made from parallel fibres (especially fibres more than 50 mm. in length) by incorporating in the yarns small quantities of an aquions solution of a binding-agent and immediately applying a false twist in one direction only in such a way that the false twist runs back at least to the point of application of the binding-agent, and thereafter, in the same run, winding the yarn. Yarn M free from twist is fed at constant speed by rollers, 1, 2 over a roller 3 slowly rotating and partly immersed in a warm solution of gelatine, to a false-twist device 6 and guide 10, and thence to winding-rollers 11, 12, there being no guide &c. between the roller 3 and false twister 6. The member 6 may be a tube or a solid of revolution e.g. a core-frustum; it may have a resilient surface; it may be rotated or oscillated in a linear or oscillating manner. The degree of twist imparted may be raised by adjusting the position of the guide 10. The material may be used for knitting or weaving with or without the insertion of twist in a further operation. Specification 850,145 is referred to.

Abstract: 973,440. Automatic voltage control. ROBERT BOSCH G.m.b.H. Nov. 16, 1961 [Nov. 26, 1960], No. 40973/61. Heading G3R. A voltage regulator for a shunt excited D.C. generator has a transistor in series with the field winding and a voltage and current responsive electromagnetic relay controls the transistor. The generator 16 supplies a battery 40 through a diode 45, and supplies the field winding 15 through a normally conductive transistor 50. The base current of transistor 50 energizes the voltage coil 53 of the electromagnetic relay which closes its contacts 51, 52 when the voltage of the generator reaches the prescribed value. These contacts short-circuit the base/emitter path of the transistor causing it to cut off, and a feed back resistor 60 applies the resulting self-induced voltage in the field winding 15 to the voltage coil 53 so that the relay opens earlier. Current limiting is effected by a coil 55 energized through a non-linear diode 56 across a resistor 44 in series with the generator load.

Abstract: 1475997 Coating glass fibre TELEPHONE CABLES Ltd 3 Dec 1974 [3 Sept 1973] 41336/ 73 Heading B2E A coated glass fibre, which may be solid or tubular, is made by progressively feeding a solid body of vitreous material into a heating zone maintained at a sufficiently high temperature to cause progressive melting of the leading end of the body, drawing a glass fibre downwardly from the molten end surface of the body and out of the heating zone to solidify on cooling, coating the fibre with a plastics material in liquid form, and causing the liquid to set to form a protective coating, the steps being carried out continuously and successively and the coating step being effected before the fibre engages any drawing, guiding or other apparatus. In particular, the fibre may be passed through a housing 13 containing a body of felt 14 which is impregnated and partially filled with liquid thermosetting plastics material 16. The lower portion of the felt body may remove excess coating material as the fibre passes through the exit orifice of the housing or an upward gas pressure may be provided in this orifice to prevent leakage. Alternatively, the fibre may be passed around a pulley 31 having a grooved or channelled rim into which the plastics material is fed from a reservoir 33, this rim thereby providing a fluid bearing for the fibre lubricated by the liquid plastics, and thence to a curing oven 17. In either method of coating, the plastics may be polyurethane solution, polyvinylacetal or polyester and the fibre is drawn through or around the coating means by means of a drum driven in synchronisation with the lead screw of the feeding machanism for the vitreous material to give a coating of constant thickness.
