Title: Process for the manufacture of azodyestuffs
IPC: C09B31/08
Filed: 1936-11-05
Abstract: Secondary disazo dyes are made by coupling diazo-monoazo dyes of the constitution <FORM:0484577/IV/1> [in which Y = H, alkyl or halogen, Z = H = or SO3H in one of the b -positions and X = the radicle of an inorganic or organic acid] with J acid or its N-aryl or N-alkyl derivatives.  They dye cellulose and regenerated cellulose in clear greenish blue shades, which on after-treating with agents yielding copper, scarcely change in shade, but become faster to light and washing.  In examples the following components are mentioned: p-amino-salicylic acid, 4-amino-6-methyl- or 6-chloro-1-phenol-2-carboxylic acid; 1-amino-2-carboxymethoxynaphthalene and its 6- or -7-sulphonic acid; the N-phenyl-, p-tolyl-, p-anisyl-, 41-hydroxy-31-carboxyphenyl-, (diphenyl-4-)-, 41-benzoylaminophenyl-, n - butyl-, and diethyl-derivatives of J acid, 5 : 51-dihydroxy-2 : 21-dinaphthylamine-7 : 71-disulphonic acid.

Title: Improvements in or relating to Thermic Telephone Systems.
IPC: H04R23/00
Filed: 1919-12-03
Abstract: 136,162. Naamlooze Vennootschap de Nederlandsche Thermo - Telephoon Maatschappij. Dec. 4, 1918, [Convention date]. Exchange systems. - A thermic telephone receiver 8 is included in the local microphone circuit, either in series or parallel with the microphone 9. The series arrangement permits the use of long battery leads, so that, for example, a central battery may be used in domestic installations, but the parallel arrangement reduces the secondary noises caused in the receiver by changes of current in the microphone. A high-resistance call-bell 10 may be connected permanently across the leads 6, 7, a condenser 11 being inserted in series with the secondary winding of the transformer 4, 5 to protect the thermic receiver from' the low-frequency ringing-currents.
Patent GB-1286910-A (GB)
Title: Multi-stage time division multiplex highway switching network
IPC: H04Q11/08
Filed: 1970-06-22
Abstract: 1286910 Automatic exchange systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT ALCATEL and SOC LANNIONNAISE D'ELECTRONIQUE 22 June 1970 [27 June 1969] 30261/70 Addition to 1286909 Heading H4K A three-stage time-division-multiplex switching network comprises an array of switches in its first stage connecting incoming to intermediate time division multiplex highways, an array of switches in the second stage connecting intermediate to further intermediate highways, and an array of switches in the third stage connecting the further intermediate highways to outgoing highways, connections across the network between an identified incoming channel and an identified outgoing channel being set up in accordance with a record in a central store of idle/ busy conditions on the intermediate highways. Separate connections are seized to constitute the transmit and receive paths of a four-wire connection. The trunking of intermediate highways is in the customary fashion with each first and third stage switch having access to each intermediate stage switch by way of one intermediate highway. To find a free route across the network each intermediate switch is considered in turn by inspecting the idle/busy channel record of the intermediate highway giving access to the intermediate switch from the first stage switch containing the calling channel and the similar record of the intermediate highway giving access to the intermediate switch from the third stage switch containing the called channel. As the switches operate on a store- and-forward basis any idle channel free on an intermediate highway incoming to an intermediate switch can be seized for use with any idle channel free on an intermediate highway outgoing from the switch. If channels are not free in both directions from one intermediate switch, the process of selection proceeds to examine the circumstances of the next switch. It is said to be advantageous to examine first those switches occupied with traffic before examining switches that are entirely free. The clearance of records on detection of release is effected from on-hook by either party, the transmit channel particulars associated with on-hook conditions being used to deduce the associated receive channel particulars in order to trace back the connection to the other party.

Title: Improvements in or relating to radio receiving sets
IPC: H03J5/24
Filed: 1929-10-08
Abstract: 341,442. Wireless receiving systems. METTES, J. J., 40, Veenkade, The Hague. Oct. 8, 1929, No. 30538. [Class 40 (v).] A wireless set can be disposed, by means of a switch, for use with either long or very short waves, so that it covers a wave-length range of from 5 metres to some kilometres. When the switch S1, Fig. 1, is turned up, if the points 1, 2, 3, 5 are all connected together while coil 10 is disconnected, the aerial is directcoupled and long waves are received, the aerial A and grid g being connected to one end of the aerial inductance 4 while the earth E and filament f are connected to the other. Reaction is provided by the coil 8, coupled to the coil 4, and is regulated by adjustment of the resistance 9. If, with the switch still turned up, the point 3 is disconnected from 2 and so from the aerial point 1, but connected to the coil 10 which is thus connected to 5, the set is a transformercoupled long-wave set, the grid coil 10 and aerial coil 4 forming the transformer. For very short waves the switch is turned down so that points 1, 5 are connected to 2<1>, 3<1> respectively. Coils 4, 10, are thus cut out, coil 8 now serves as an anode-circuit choke-coil only, the aerial is coupled to the grid by the short-wave autotransformer 11, and reaction is provided by the condenser 14. A shortening-condenser 21 may be put into series with the aerial. In the modification shown in Fig. 2, when the switch S2 is turned up for longwave reception the aerial is direct-coupled to the detector and reaction is provided by the coupling 4, 8. When the switch is turned down, however, a Reinartz circuit adapted for short-wave reception is obtained. The tappings a, b, c of coil 11 are then connected to aerial, earth and grid respectively, reaction being afforded by the coil 18 and condenser 14 connected between aerial and anode.
