Title: Method to measure the amplitude-frequency response curve over a fm-transmission system
IPC: H04B3/46
Filed: 1962-08-03
Abstract: 962,367. Distortion measurements. STANDARD TELEPHONE & CABLES Ltd. Aug. 3, 1962 [Aug. 4, 1961], No. 29961/62. Heading G1U. The amplitude-frequency response curve of a FM transmission system is measured by superimposing a test frequency on a sweep frequency and varying the test frequency between 1/20 and “ of the 3-dB bandwidth of the transmission system. The embodiment illustrated is a differential slope measuring set as in Specification 866,257. The sweep frequency #s is selected to lie below the bandwidth of the test system 1. The test frequency #T is deliberately chosen to be sufficiently high that the amplitude-frequency response of the system 1 under test is no longer linear since it is in this region information is obtained as to the causes of distortion. The feature of the invention is to vary the test frequency over the range 1/20 -1/4 of the bandwidth of the test system. This can be done continuously, either manually or automatically, or the frequency can be switched over the range according to a predetermined programme.

Abstract: 971, 870. Testing relative magnitudes of electric signals. ULTRA ELECTRONICS Ltd. Aug. 28, 1961 [Sept. 1, 1960], No. 30123/60. Heading G1U. [Also in Divisions G3 and G4] A circuit having two inputs is arranged to provide an output which is proportionate only to that one of the inputs which is chosen, the choice being of that input which is the algebraically smaller or greater, or arithmetically smaller or greater. As shown, two inputs 11, 12, proportionate respectively to the speed and a temperature of a gas-turbine, are fed to an additive circuit 13 and a subtractive circuit 14. The additive circuit is polarity-conscious, the subtractive circuit magnitude-conscious without regard to polarity. The resultant outputs 15, 16 are fed to a polarity-conscious circuit 17, which, when additive, has an output 18, which is proportional to the input which is algebraically the greater. Conversely, when circuit 17 is subtractive the output 18 is porportional to the input which is algebraically the smaller. It is stated that the circuits can be formed from push-pull magnetic amplifiers, the circuit 14 being followed by a fullwave rectifier to ensure the output is unidirectional. By modification of the circuit so that circuits 13, 14 are magnitude conscious, it can be arranged to provide an output which is proportional to the input which is arithmetically the greater or smaller by making circuit 17, respectively, polarity or magnitude conscious.

Title: Method of reducing the halogen content of halophenols
IPC: C07C37/00
Filed: 1956-10-05
Abstract: The halogen content of chloro- or bromophenols is reduced by bringing the vapours thereof together with hydrogen into contact with a cuprous halide supported on porous activated alumina, the weight of cuprous halide being from 1 to 25 per cent of the weight of alumina, at temperatures of from 350 DEG  to 550 DEG  C.  The catalyst is preferably a fluidized bed in the reaction zone and it may be formed by impregnation of alumina with cupric compounds such as the chloride or oxide with subsequent reduction to cuprous compounds and, if necessary, conversion to halide under conditions of the reaction. The hydrogen may be generated in the reaction zone by, for example, the water-gas reaction.  In examples: (1) o-chlorophenol reduced according to the invention gives phenol; (2) 2 : 3 : 4 : 6-tetrachlorophenol reduced according to the invention with 2 mols. of hydrogen gives a major proportion of 2 : 4-dichlorophenol with minor amounts of 2 : 3 : 4-, 2 : 3 : 6- and 2 : 4 : 6-trichlorophenols, 2 : 3-, 2 : 6- and 2 : 5-dichlorophenols, o-, m- and p-chlorophenols and phenol; (3) 2 : 4 : 6-trichlorophenol with 1 mol. of hydrogen gives a major proportion of 2 : 4-dichlorophenol and minor amounts of 2 : 6-dichlorophenol, o- and pchlorophenols and phenol.  It is also stated that bromphhenols give analogous results.ALSO:A catalyst comprising a cuprous halide supported on porous activated alumina, the weight of cuprous halide being from 1 to 25 per cent of the weight of alumina, is prepared by impregnating the alumina with a cupric compound, e.g. the chloride or oxide, and reducing the impregnated mass with, if necessary, conversion to halide.  In an example, porous activated alumina is impregnated with 15 per cent of its weight of cupric chloride and reduced with gaseous ethylene at 480 DEG  C. in a fixed bed reaction tube.  The catalyst is used in the reduction of the halogen content of halophenols with hydrogen.

[Class 2 (ii)] Viscose of low hemicellulose content is obtained from ground, preliminarily ripened or, unripened alkali cellulose. The tufts of alkali cellulose are moistened or worked up to a dough with a quantity of 8-12 per cent* NaOH not exceeding three times the weight of the alkali cellulose and of low hemicellulose content if any. After standing one or more hours, the alkali. together with dissolved hemicellulose is pressed out, and the alkali cellulose is loosened again. It is then treated with a mercerizing lye of 18 per cent or more of NaOH, excess alkali is pressed off, and the material is again loosened. The alkali-cellulose is then xanthated and dissolved in alkali to form viscose. The doughing and pressing-off. with dilute washing lye may be repeated and a comparatively high pressure may be used in pressing-off after the last treatment with washing lye. The pressedoff final mercerizing lye may be used in the production of the washing lye, and the used washing-lye may be utilized for the immersion lye for the cellulose. The viscose obtained may be extruded into an acid spinning bath, and the filaments obtained may be subjected to a high degree of stretching.

Abstract: 883,972. Automatic voltage-control systems. BOSCH G.m.b.H., ROBERT. Sept. 8, 1959, No. 30675/59. Class 38 (4). In an automatic voltage-regulating system for a generator, a first relay, having a shunt coil, controls a generator field to keep the voltage constant up to a predetermined current at which the first relay ceases to operate and a second relay, having at least a current coil, controls the field to give a decreasing generator voltage with increasing current. As shown, a generator A has an armature 10 shunted by a field 17 in series with a resistor 19. A relay B has a core 21, a shunt coil 78 and an armature 24, biased by a spring 27, carrying contacts 38, 39 co-operating with contacts 37, 40. A relay C has a core 22, a series coil 72 carrying the armature current, a shunt coil 83, and an armature 25, biased by a spring 28, which carries contacts 33, 34 co-operating with contact 90, 91. Below a predetermined armature current the relay B controls the generator voltage by the armature 24 vibrating under the action of the flux due to the coil 78 to initially open contacts 37, 38, to remove a short-circuit across the resistor 19, and at a higher generator voltage close contacts 39, 40 to short-circuit the field 17. Over the predetermined current the armature 25 vibrates due to the coils 72, 83, acting cumulatively, to open contacts 33, 90 and close 34, 91 shorting- out the field 17. With the reduction in the generator voltage due to the operation of relay C, the relay B ceases to operate and the generator voltage falls with increase of armature current. The relay C may be modified by fitting only the current coil 72. A relay D, having a shunt coil 86 and reverse current coil 74, connects the generator to a battery 46.
