Patent GB-676857-A (GB)
Title: Improvements in the production of surface-active compounds
Filed: 1950-11-08
Abstract: Salts of non-aromatic sulphimides are made by the reaction of gaseous or liquid ammonia with sulphohalides and treatment of the amidation products with organic or inorganic basic substances, the sulphohalides being obtained by treatment of mixtures of non-aromatic hydrocarbons of B.R. 120-200 DEG  C. with sulphur dioxide and halogen, if necessary the resulting sulphimides, in so far as they still contain sulphamides, are reacted with an amount of sulphohalide corresponding to the sulphamide content in the presence of alkali, the sulphimide is separated by acidification, and then reacted with the basic substance.  Molar amounts of sulphur dioxide and halogen may be used in the sulpho-halogenation but halogen may also be used in excess, products then being obtained which contain varying amounts of non - hydrolysable, chain - combined halogen.  Hydrocarbons specified are test and lacquer benzines, those obtained by hydrogenating coals, tar oils and bitumens and especially those from the hydrogenation of carbon monoxide.  It is usually advantageous to purify the hydrocarbon before sulphohalogenation by catalytic hydrogenation or by treatment with sulphuric acid or aluminium chloride. Sulphohalogenation is preferably effected so that 70 per cent or less of the hydrocarbon is converted.  Basic substances mentioned are hydroxides and carbonates of alkali metals, ammonia, methyl-, dimethyl- and triethyl-amine, pyridine and mono-, di- and tri-alkylolamines.  The products are fast to alkali and may be used in alkaline baths.  In examples: (1) a Baden petroleum fraction of B.R. 140-175 DEG  C. is hydrogenated in the presence of a nickel catalyst, treated with SO2 and Cl2 and short wave light to convert about 40 per cent of the hydrocarbons, a part of the mixture thus obtained is reacted with liquid ammonia, washed with dil. HCl, dissolved in benzine and treated with an equal quantity of the sulphohalide solution in the presence of caustic soda solution when after washing with dil. HCl the sulphimide is separated and neutralized with caustic soda solution to provide the salt, if Cl2 is present in excess during sulphohalogenation a product containing non-hydrolysable chlorine is obtained and (2) benzine from the hydrogenation of CO is catalytically hydrogenated and a fraction of B.R. 150-190 DEG  C. is sulphochlorinated and further treated as in (1) save that ammonia gas is used in place of liquid ammonia and triethanolamine is used to neutralize the sulphimide.  Specification 684,332 is referred to.

Abstract: 983,933. Optical apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 28,1961 [Aug. 2, 1960],No. 27471/61. Heading G2J. [Also in Division H4] In a colour television camera image light is split into red, blue and green components by means of dichroics carried by the surfaces of prisms the latter serving to direct the component colours to the corresponding pick-up tubes of the camera. Fig. 3, shows one embodiment in which a dichroic layer 321 carried by a first prism 310 reflects the red component of image light from objective lens 311 and transmits the blue and green components through an air gap into a second prism 320 carrying a dichroic layer 322 which reflects the blue component and transmits the green component. The separated components are then directed to the red,blue and green pick-up tubes 312, 313, 314 respectively by the refracting action of the prisms, a further prism 317 being employed in the optical path to green pick-up tube 314,which in addition to allowing the pick-up tube to be positioned as shown, also serves to equalize the three optical paths. Since the prisms surfaces and dichroic layers make only small angles with planes normal to the optical axis polarization of the light and colour variation across the image field is stated to be largely avoided. To assist the colour selecting action of the dichroics the "output" surfaces of the three prisms may, additionally, be provided with appropriate colour filters. Other arrangements are described involving further prisms between the dichroic carrying prisms (Fig. 2, not shown) and, additionally, between the objective lens and the first dichroic carrying prism (Fig. 1 not shown).

Title: Textile yarns and fabrics and edge-crimping apparatus and processes for producing them
IPC: D02G1/10
Filed: 1960-08-12
Abstract: 909,362. Finishing yarns. DEERING MILLIKEN RESEARCH CORPORATION. Aug. 12, 1960 [Aug. 18, 1959], No. 28016/60. Class 120 (3). In an edge-crimping process, linearly advancing, heated or unheated yarn (composed of or containing continuous filaments of thermoplastic material) is passed through an abrupt bend the radius of curvature of which is intermittently altered. The resultant yarn may comprise crimped lengths alternating uniformly or in random manner with similar or different lengths which are not crimped or are crimped to a lesser extent. Crimping apparatus may comprise an element having an edge engageable by the yarn and which is intermittently rendered ineffective in crimping the yarn. As shown in Fig. 1, yarn Y passes through a tension regulator 14, over and in contact with one (curved) surface of an electrically heated strip 19, thence with an abrupt change of direction across the edge 17a of a blade 17, which may be maintained at a temperature considerably below that of the strip, and treated yarn, possessing a small evident crimp and a larger permanent latent crimp, is wound by take-up apparatus 23. The yarn is moved away from, and allowed to return into, contact with edge 17a by a spring- loaded arm 23 loosely, pivotally and adjustably mounted on a shaft 27 and intermittently displaced by a pin 35 of a continuously rotated eccentric 31. The yarn-engaging edge 25a of arm 25 has a much larger radius of curvature than the edge 17a and has little or no crimping function In another apparatus, Fig. 3, yarn Y passes over a heater strip 119 and blade 117 from contact with the edge 117a of which it is removed by the transversely bent portion 125a (of relatively large cross-sectional radius of curvature) of a wire arm 125 which is oscillated about a pivot 127 by the action of a spring 137 and the armature 131a of a solenoid 131 which is intermittently actuated by a generator 141 yielding uniform i.e. fixed-pattern, or random signals of predetermined frequency and duration. The latent crimp is subsequently developed in the yarn, prior to or after formation of fabric therefrom, as by hot moisture, hot air or contact heater treatment or by long-standing exposure in relaxed state at normal temperature.

Title: Apparatus for reproducing quadraphonic sound
IPC: H04S3/02
Filed: 1972-06-15
Abstract: 1384610 Quadraphonic systems SONYCORP 15 June 1972 [21 June 1971] 28111/72 Heading H4R A decoder for a matrixed quadraphonic sound reproduction system has all pass phase shifting networks in the dematrixing circuit. Each phase-shift network includes a phase splitter, the outputs of which are used to derive gain logic switching signals to control the amplitudes of the signals fed to the respective loudspeakers to provide enhanced discrimination between front and rear signals. As described the matrixed input signals L T  and R T  include respectively the left front Lf and right front Rf signals together with both rear signals L b  and R b , with the signals L b  and R b  in one input signal being in quadrature with the same signals in the other input signal, but with L b  in one input leading the L b  in the other input and R b  in the one input lagging the R b  in the other input, Fig. 2 (not shown). The signal L T  is applied to phase shifting circuits 212, 222 which produce at their outputs signals having a phase difference of 90 degrees. Similarly the R T  signal is applied to phase shifting circuits 242, 232 to produce signals having a phase difference of 90 degrees, and these signals directly, or after combination in adders, produce output signals L<SP>11</SP> F , L<SP>11</SP> B , R<SP>11</SP> F , R<SP>11</SP> B , in which the original signals L F , L B , R F , R B  respectively predominate. Each phase shifter includes a respective transistor phase splitter 213, 223, &c., from which the signals L T  and R T  may be taken either in their original phase or phase inverted, and from these signals gain controlling signals L T +R T  and L T -R T  are derived to feed rectifiers 254, 256 and difference circuit 258. The arrangement is such that a front centre signal gives a predominant L T +R T  signal and a rear centre signal gives a predominant L T  - R T  signal and these conditions are used to control the gain of amplifiers 215, 225, 235, 245, so that a front centre signal differentially increases the gain of the amplifiers feeding the front loud-speakers and a rear centre signal differentially increases the gain of the amplifiers feeding the rear loudspeakers.
