Title: Monoazodyestuff
IPC: C09B29/20
Filed: 1951-08-17
Abstract: The invention comprises a monoazo dyestuff of the formula <FORM:0689761/IV (c)/1> and the preparation thereof by coupling 2 : 3-hydroxynaphthoic acid o-toluidide with diazotized 1 - amino - 2 - methoxybenze - 5 - sulphonic acid p-nitrophenyl ester.  The preparation of the dyestuff is preferably effected by reducing the coupling component to a fine easily coupling form and then adding the diazo solution, coupling being effected at congo-acid reaction, if desired with neutralization of mineral acid with salts of organic acids, and advantageously in the presence of surface-active compounds.  The dyestuff may also be prepared in the presence of a substratum, e.g. by adding an aqueous slurry of freshly precipitated barium sulphate to the solution or suspension of the coupling component.  The dyestuff is useful in graphic printing, for staining wall paper and for colouring lacquers and plastics.  In examples, coupling is effected (1) in the presence of a sodium alkyl (C16-18) sulphonate or other surface-active substance, e.g. the condensation product of oleyl chloride and sodium aminoethanesulphonate or sarcosine, and (2) with the addition of sodium acetate.

Title: Improvements in switches for high-frequency electrical oscillations
IPC: H01P1/12
Filed: 1947-07-29
Abstract: 637,121. Keying carrier frequencies. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. July 29, 1947, No. 20423. [Class 40 (v)] [Also in Group XL (b)] A switch for high-frequency oscillations comprises a uniform line an integral number of quarter wavelengths long connected at one end to the terminals to be switched and a conductor which can be placed so as to couple the line by a reactance - X to a second line of reactance +X, or withdrawn to give negligibly small coupling. As shown, a coaxial line 10 is connected at one end to the terminals 15, 16 to be switched. A second coaxial line 11 is arranged with its outer conductor continuous with that of line 10 and a bellows 19 is formed so that the enlarged ends of inner conductors 17, 18 may be approached or withdrawn. The line 11 may be open or short-circuited and has an equal and opposite reactance to that of the capacity between the enlarged ends of the inner conductors. One inner may be provided with a spigot co-operating with a recess in the end of the opposing inner, Fig. 4 (not shown), or a separate conductor may act as a coupling. Two switches in parallel spaced apart by a quarter wavelength may be used in each of two branch lines. The common feeder is a quarter wavelength from the nearest switch and is effectively connected to the line in which the couplings are operative. Specification 564,988 is referred to.

Title: Improvements in or relating to echo sounding recorders
IPC: G01S1/72
Filed: 1938-03-19
Abstract: 515,826. Echo-sounding apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. and HINTON, N. P. March 19, 1938, No. 20437/39. Divided out of 515,202. [Class 118 (ii)] In an echo-sounding arrangement of the type in which a recording member sweeps over a recording surface the range in which the depth lies is tested by emitting a signal at the commencement of the first sweep, the recording member being operative during the sweep, transmission then ceasing until the number of sweeps corresponding to the number of ranges has been completed. For the second range, a signal is emitted at the commencement of one sweep but the recorder is operative during the next sweep following, and so on until the range is found. When this has been done, a switch is thrown to double, treble &c. the frequency of sounding. Cam AC, on shaft SH rotating at twice the speed of shaft HS, operates the arm of the recorder. With the range switch RS in the 750 position, a transmission circuit is completed over contacts CT, TC750, the operating contours of cam CH being displaced by 90 degrees so that only one transmission is made for every two revolutions of shaft SH, at the beginning of a sweep of the recorder arm. The recorder circuit is completed during this sweep over contacts RC750. If an echo is recorded, switch PP is closed, shorting contacts CT and connecting contacts RC2250 in parallel with RC750 so that transmission occurs at the beginning of each forward sweep, the recording member being operative throughout the sweep. On rotating the range switch to the 1500 position (as shown) transmission occurs over contact TC1500 at each alternate back sweep recording occurring in the next forward sweep. In the 2250 position, transmission occurs on each alternate forward sweep, recording being possible in the next forward sweep. To deal with very small depths such as O-150 an additional contact TC150 and corresponding switch positions are provided while an extra cam C150 is rendered effective to drive the recorder arm at a higher speed.
