Patent GB-591979-A (GB)
Title: Improvements in or relating to vat dyestuffs
IPC: C09B5/28
Filed: 1945-05-11
Abstract: An olive vat dyestuff is obtained by treating di - 11 - 111 -anthraquinonyl - 1 - 5 - diaminoanthraquinone with a solution of caustic potash in an alcohol (e.g. methyl or ethyl alcohol) at 130 DEG  to 200 DEG  C.  The product may be submitted to the action of halogenizing agents, e.g. chlorine, bromine or sulphuryl chloride, in the presence or absence of a halogenation catalyst, e.g. iodine.  In examples: (1) di-11-111-anthra-quinonyl - 1 - 5 - diaminoanthraquinone is heated with potash in methyl alcohol to produce a dyestuff with dyes cotton in olive shades; (2) the dyestuff obtained in (1) is treated with sulphuryl chloride in the presence of iodine to produce a dyestuff yielding shades of greater intensity than (1).  The Specification as open to inspection under Sect. 91 refers also to the condensation of the halogenized dyestuffs with organic substances containing a hydrogen atom capable of reaction, such as aminoanthraquinones and aminoanthraquinone-acridones, thus forming a new series of dyestuffs.  This subject-matter does not appear in the Specification as accepted.

F., 383, Watford Way, Hendon, all in London. April 24, 1933, No. 11959. [Class 40 (v)] A neon tube 5, or other load which cannot be readily matched to a valve, is connected in parallel with one output valve 3 of an amplifier and in series with another 4, and the signals are applied to the grids of the valves in opposite phase. The neon tube is connected across resistances 9, 10 which provide grid bias for the valve 4. The signals applied to the valve 4 are reversed in phase by passing them through an extra valve 2. According to modifications : the output valves are in series, and the choke 7 and resistance 8 in series with the neon tube are isolated from direct current by a condenser ; transformers are used for phase reversal, Figs. 5 and 6 (not shown).

Title: Improvements in or relating to the measurement of cross-talk on telephone circuits
IPC: H04B3/46
Filed: 1925-05-08
Abstract: 254,838. Callender's Cable &, Construction Co., Ltd., and Urmston, J. May 8, 1925. Telephone, systems.-The cross-talk between two telephone circuits A, B is measured by supplying alternating current from a generator D to one of the circuits A and also to a crosstalk meter H and allowing the currents produced in the circuit B and in the output circuit of the meter to act simultaneously and in opposition upon an indicator device such as a telephone receiver G which may be associated with the testing circuit through a transformer having two primary windings F, F<1>. A phase-shifting transformer J is connected in the meter circuit and this and the meter H are adjusted until no sound is heard in the telephone. The readings of the meter H and transformer J then give respectively a measure of the intensity of the cross-talk and of its phase displacement. The supply transformer and the meter H may have earthed screens D<1>, D<3>.

Vacuum tubes; low-pressure metallic-vapour apparatus.-To diminish the potential drop in thermionic valves, a filling of gas or mercury vapour or both is introduced and either (1) a main discharge is produced between an anode C and and incandescent cathode B, while the telephone or its equivalent is connected to an auxiliary anode E associated with a control grid D, as shown in Figs. 3, 5, and 6, or (2) a rod R, Fig. 4, of vaporizable material is associated with the cathode B to form a conductive path between the anode and the cathode. In the first construction the discharge from the anode C may be prevented from clinging to the grid D by a screen F, which may be of insulating material or of conductive material adapted to be connected to a source of potential. To provide a filling of mercury vapour, one end of the cathode may connect with a mercury pool G, Fig. 5. In the construction shown in Fig. 6, the anode E is of annular form and is enclosed by the grid D, the lead to the anode C is covered with insulating material K, and a vaporizable rod R is inserted in the cathode. The cathode filament may have a high heat inertia so that it may be heated by alternating current. The grid may be in the form of an internal or external magnet coil through which the current flows.

IPC: G06G1/02
Filed: 1919-05-16
Abstract: 151,670. Baker, W. F., and Burns, S. B. May 16, 1919. Logarithmic calculators for computing wages, percentages, and the like comprises three coaxial cylinders, the centre one of which is relatively rotatable, and a slide or cursor pivoted on the axis of the cylinders and provided with arms, on the outer ends of which are percentage or other logarithmic scales for use in conjunction with the numerical and monetary scales on the cylinders. The end cylinders A, C, Fig. 3, are secured to a shaft S by means of keys and rings J, and the centre cylinder B is normally free to rotate, but can be locked to the cylinder A so as to rotate with the shaft S by means of a spring-pressed collar M controlled by a tongue T, rod Q, and lever P, which lever when turned through a right-angle withdraws the collar M from engagement with the cylinder B to release the same. The cylinders A, C, as shown in Figs. 8 and 9, are marked with a numerical scale and two monetary scales, those on C being set out to half the base of scales on A. The sides of the cylinder B adjacent the cylinders A, C are graduated to correspond to the scales on these cylinders respectively. A slide DEF, Fig. 2, moves freely over the face of the cylinders, and is pivoted by means of balanced arms to the shaft S. The strips D, E, and F of the slide are made of celluloid or other material, and are marked with percentages of various amounts to correspond with the scales on the cylinders. In calculating compound interest, a separate strip a, Fig. 10, which can be fixed to the slide DEF, is provided for each end cylinder. Examples of the use of the device are set forth in the Specification.

Each series is of shorter duration than a half period of the current and extends on both sides of the zero point of the current. A high current generator 1 supplies the current through current limiting choke coils 2 to the apparatus 3 to be tested. A generator 4 supplies an alternating current of high voltage of the same frequency as the generator 1, the generators 1, 4 being mechanically connected. The voltage of the generator 4 is applied to a capacitor 6 through a transformer 5 and a resistor 7. The capacitor 6 is connected to the apparatus to be tested through a constant spark gap 8 and a resistor 9, the spark gap being located in a strong air current in order to put an early stop to the discharge of the capacitor 6. During the time that the voltage of the capacitor 6 is higher than the spark voltage of the spark gap 8 voltage impulses are applied to the apparatus 3 to be tested, a series of impulses being applied during each half period. The position of this series with regard to the zero point of the current may be regulated by adjusting the phase difference between the high voltage generator 4 and the generator 1, e.g. by rotating the stator of the generator 4.
