Title: Improvements in or relating to reception of telegraph signals
IPC: H03K3/04
Filed: 1930-04-03
Abstract: 352,401. Multiplex code telegraphy. STANDARD TELEPHONES & CABLES, Ltd., SANDEMAN, E. K., CHANTER, A. J., and CURRAH, L. E., Columbia House, Aldwych, London. April 3, 1930, No. 10571. [Class 40 (iii).] Multiplex telegraph receiving equipment comprises a distributer and in each channel, for the purpose of distending the received signals, an arrangement comprising two thermionic valves having electrically symmetrical grid and plate circuits. The plate circuit of each valve is connected to the grid circuit of the other valve so that an electric impulse applied to the grid of either valve causes a charge in the plate circuit current in that valve to be applied to the grid of the other valve whereby the anode current of one valve is reduced and that in the other increased until a condition of stable equilibrium is reached and maintained. The circuit is restored to normal by an extra brush and set of segments on the distributer. The circuit shown in Fig. 3 has two states of equilibrium, viz. (a) when current is flowing through the valve 1 and produces in a resistance 14 sufficient voltage so to bias the grid 21 of the valve 2 that no current passes through it, and (b) when current flows through the valve 2 and not through the valve 1. Signal voltages from a line 61 are applied by amplifiers 71, 72 to resistances 17, 27 so that positive signals produce one state of equilibrium and negative signals the opposite state. Recorders mav be connected across resistances 14, 24, or, if it is desired to avoid inductance in the plate circuits, the receiving relay is connected in the plate circuit of a valve with its grid connected to that of one of the valves of the shaping circuit, Fig. 9 (not shown). According to modifications, the effect of earth capacity in batteries 16, 26 is avoided by connecting them in series with a pair of resistances in parallel with a condenser, Fig. 4 (not shown) ; the effects of small variations in the batteries are obviated by connecting resistances 18, 28, Fig. 7, to a potentiometer, Fig. 6 (not shown), or as shown.
Patent GB-807575-A (GB)
Title: New trisazo-dyestuffs containing an ortho:ortho-dioxy-azo grouping and complex metal compounds thereof and processes for their manufacture
IPC: C09B31/20
Filed: 1955-04-13
Abstract: The invention comprises dyestuffs of formula: R1-N=N-R2-N=N-R3-N=N-R4 where R1 is a benzene residue containing OH para to the azo link and COOH ortho to the OH, R2 is a naphthalene residue bound in para-position to the azo links, R3 is a benzene residue bound in para-position to the azo links and containing OH ortho to -N=N-R- and R4 is a naphthalene residue containing OH as sole auxochromic group in a position vicinal to the azo link and at least one SO3H group. The invention includes metal complexes of the above dyestuffs the metallization being across the two o : o1-dihydroxy groups.  Cobalt, nickel and copper complexes are described, the latter being preferred.  The metal complexes are made by known processes by metallizing with dealkylation dyestuffs corresponding to those above but containing an alkoxy group in place of the OH group in R3, any metal addition at the OH-COOH grouping being removed by treatment with an agent such as dil. HCl.  The metal-free dyestuffs are made by the vigorious demetallization of their complexes, agents such as concentrated HCl and alkali metal cyanides and sulphides being specified.  The starting dyestuffs containing the alkoxy group are made by coupling a diazo compound R1NH2 with HR2NH2, diazotizing the resulting amino-monoazo-dyestuff and coupling with H-R3NH2 and diazotizing the amino-diazo-dyestuff thus obtained and coupling with H-R4.  Components R1NH2 specified are 1-amino-4-phenol-3-carboxylic acid and its 5 - chloro - derivative.  Components HR2NH2 specified are 1-naphthylamine and its 6- and 7-sulphonic acids.  Components HR3NH2 specified are 1-amino-2-methoxy-and -ethoxy-, -2-methoxy-5-methyl- and -,2-dimethoxy-benzenes.  Specified end components are 1 naphthol-4- and -5-mono- and -3,6- and -3,8-di-sulphonic acids, 1-naphthol-8-chloro-3,6-disulphonic acid and 2-naphthol-5-, -6- and -7-mono- and -3,6- disulphonic acids. Advantageously the dyestuff molecule contains two SO3H groups.  The metal-free and metal-containing dyestuffs dye animal fibres, e.g. wool, silk and leather, but especially cellulosic materials e.g. cotton, linen, artificial silk and regenerated cellulose fibres.  The metal-free dyestuffs or their couplers may be metallized on the fibre or partially on the fibre and partially in the dye-bath, cf. Specification 455,274, [Group IV], and after-treatments as in Specification 619,969 may be applied.  Examples are provided of the use of certain of the above specified components in the preparation of metal-free dyestuffs and their copper complexes the metal-free dyestuffs yielding grey tints on cotton which become redder on coppering.

Abstract: 848,217. Copying-telegraph receivers. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 3, 1957 (April 3. 1956: April 9. 19561. No. 10918/57. Class 40(3)  [Also in Groups XVI and XXXVIII] A mechanism for forming character pattern on a movable magnetic surface 24 comprises a magnetic head assembly, Fig. 1, having a column of individual elements which are selectively energized as the magnetic surface moves past the head, so that the character is formed by a successive series of vertical columns, the energization of the heads being determined by a character generator 12<SP>11</SP>, Fig. 8, selectively conditioned by a decode matrix which is responsive to incoming signals e.g. a 6 bit code store 42. As shown the magnetic surface 24 is on a drum 4<SP>1</SP> upon which characters are formed by a column of nine elements 6<SP>1</SP>. The elements each comprise a magnetic core 3 inserted in a conductive sleeve 6 which is fitted in a base 8. The sleeve 6 forms part of a secondary circuit of a transformer 20 so that when an appropriate amplifier 30 is pulsed energizing a winding 22 of the transformer 20, a magnetic flux F, Fig. 2, is set up to form a magnet mark on the surface comprising a spot of one polarity surrounded by a ring of opposite polarity. Magnetic ink is then applied to the magnetic surface which then transfers the image to an absorbent paper. The character generator comprises a number of magnetic cores 22a, Fig .7, each provided with a read-in, a read-out and a sense winding. The read-in windings are operated from the decode matrix to determining which character image is to be formed and the read-out windings are pulsed by an element ring 26 which pulses each all character increment positions column-bycolumn through lines I1 to 17 and lines 24-1 to 24-7. The element ring 26 is under control of a "Sync" pulse or line 38 from a head 36 sensing a track 34. When both a read-in and a read-out winding is energized in one core, the sense winding will be energized to operate the associated amplifier 30, while the core will be reset. The decode matrix (Fig. 9 not shown) comprises six rows of cores each including a code core. The cores are arranged in Christmas tree fashion, 2, 4-64, in binary lines 1, 2-x respectively and which are energized selectively in conjunction with a core stepping register which sends a pulse to each of the six rows seriation, the appropriate read-in lines for the various characters are energized.

Filed: 1919-05-07
Abstract: 149,069. Barr, J. F. May 7, 1919. Heating by electricity. - Electrically-beated sterilizing-apparatus is fitted with mechanism, controlled by the float-feed water valve, for cutting off the current automatically when the water in the sterilizing chamber falls to a pre-determined level and for preventing the re-engagement of the main switch until the water rises above the predetermined level. As shown in Figs. 2 and 5, 2 is the sterilizing chamber and 4 the electric heaters. The left-hand chamber is divided longitudinally into two superposed chambers by a diagonal partition d; the upper chamber containing the float-feed valve and the supply water, and the lower chamber the switch mechanism. The switch mechanism comprises four main members, (1) a spring-mounted handle member k carrying a laterally-projecting spring blade l fitted with a projection m, (2) a spring-mounted bifurcated arm g carrying a latch h and the contact, member g' respectively on the two arms, (3) a third fixed arm e carrying another spring blade having an inclined projection f, and (4) a pair of contacts g<2> for receiving the member g<1> in the " on " position of the switch. Normally when the handle k is raised, the member m lifts the arm g and the member h trips the spring blade and rests on its upper edge as shown at h<1> to retain the switch in the " on '' position. When the water falls to the predetermined level, a rod c attached to the float arm moves the member f laterally and releases the catch h, leaving the spring o free to withdraw the arm g to break the circuit. Should continued pressure be put on the handle k in attempting to engage the switch while the member f is displaced, the member m trips the'bar g and the spring o breaks the circuit as before. The switch chamber is provided with a glazed opening behind which a lamp or glowing resistance is placed to indicate when the current is on. The apparatus is stated to be adapted specially for use with the electric sterilizer described in Specification 111,736, [Class 81 (i), Disinfecting &c.].
