Abstract: 681,478. Radio receiving apparatus; aerials. COLE, Ltd., E. K., and BURNARD, C. L. Feb. 15, 1951 [Feb. 17, 1950], No. 4071/50. Classes 40 (v) and 40 (vii). In a radio receiver comprising a mediumwave loop aerial L<SP>1</SP> and a separate long-wave loop aerial L2, for long waves, the mediumwave loop forms part of a tuned circuit adapted to improve the long-wave selectivity, while on medium waves, the long-wave loop L<SP>2</SP> forms part of an absorption wave trap for a predetermined unwanted frequency. An external aerial AE may be connected to the medium-wave loop if desired. Switches S<SP>1</SP> and S<SP>2</SP> are shown in the long-wave position so that the medium-wave loop aerial L<SP>1</SP>, which is inductively coupled to the long-wave loop aerial L<SP>2</SP>, is tuned by condenser C<SP>1</SP>. The circuit L<SP>1</SP>, C<SP>1</SP> is tuned to a frequency between the highest long-wave frequency (e.g. 300 kcs.) and the intermediate frequency (e.g. 470 kcs.), thus reducing the response to image frequencies. For mediumwave reception, switches S<SP>1</SP> S<SP>2</SP> are turned to position B, and the resonant circuit L<SP>2</SP>, C<SP>2</SP> then forms an absorption wave trap for a predetermined unwanted frequency, which may be the intermediate frequency. Variable condenser C<SP>3</SP> is used to time both the medium- and longwave loops. Details of the number of turns and spacing of the loop aerials are given, and the loop L<SP>2</SP> may be placed within the area enclosed by loop L<SP>1</SP>.

Filed: 1966-08-31
Abstract: 1,161,674. Bulking yarn. ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI, GENERALNI REDITELSTVI. 31 Aug., 1966 [1 Sept., 1965], No. 4134/69. Divided out of 1,161,673. Headings D1F, D1J and D1W. A method of bulking staple fibre yarn containing fibres with different degrees of potential shrinkage comprises feeding the yarn by means of a gas stream into a chamber where the yarn is accumulated, and heated to cause differential shrinkage of the fibres. The yarn may then be advanced to a winding, knitting, or weaving operation. The yarn is heated in the chamber by either the chamber being electrically heated or by using steam or hot air as the gas. The chamber gradually widens in cross-section, which may be circular, elliptical, square, or rectangular, from a gas nozzle at the inlet end to the outlet end where the cross-section abruptly decreases. The chamber is perforated to allow the gas to escape with the perforations preferably being located in grooves along the inside of the chamber. The chamber may have a device to sense the amount of yarn therein and to control the nozzle and/or the rollers feeding the yarn to the nozzle. The yarn stored in the chamber may also constitute a reserve between a knotter and the bobbin on which it is being wound, as in Specification 1,031,608.

Title: Improvements in or relating to titanium pigments
IPC: C22B34/12
Filed: 1936-02-11
Abstract: In the production of titanium dioxide, a titanium sulphate solution containing at least 30 grms. per litre TiO2 is treated with an acid binding compound of an alkali or alkaline-earth metal or ammonia in such quantity that less than 0,2 mol. of unneutralized H2SO4 bound to titanium remains per mol of TiO2 present (and without neutralizing any substantial amount of H2SO4 bound to iron and other bases), whereby substantially only the titanium present is precipitated, the precipitate being washed and redissolved to give a purified solution which after concentration if necessary s hydrolyzed to reprecipitate the titanium which is subsequently washed and calcined.  In carrying out the process, an alkaline-earth hydroxide may first be added in insufficient quantity to precipitate the titanium, and the titanium be precipitated after separation of the insoluble sulphate formed by an alkalior alkaline-earth-hydroxide or ammonia, ammonia being preferably used when manganese is present as it assists removal of this impurity.  At any stage prior to precipitation of the titanium a soluble sulphide may be added to precipitate a portion of the impurities.  Re-solution of the titanium precipitate in acid is preferably effected in the presence of an added soluble compound of trivalent titanium, such as the sulphate or fluoride. Examples of operation are given.  Specifications 364,613 and 449,327 are referred to.
