Title: Manufacture of new para-aminobenzene-sul honamide derivatives
IPC: C07D277/52
Filed: 1943-06-28
Abstract: p-Aminobenzene-sulphonamide derivatives are obtained by treating a p-aminobenzene-sulphonamide with an oxo-compound of general formula R1-CO-R2 wherein R1 represents H or an organic residue, and R2 represents H or a carboxyl or carbalkoxy group or a salt thereof, and a compound containing a reactive SH- group and also containing a salt-forming group when the oxo-compound does not carry such a group and, if required, converting the product into a water-soluble salt by treatment with a base or an acid the products carry in the amino radical of the benzene nucleus a substituent of the formula <FORM:0584188/IV/1> wherein R1 and R2 have the meanings assigned above and wherein R3 represents an organic residue carrying a salt-forming group if neither R1 nor R2 contains such a group. Reaction is effected by (a) treating the starting-materials in admixture with one another; (b) condensing the p-aminobenzenesulphonamide with the oxo-compound followed by treatment with the compound containing a reactive-SH-group; (c) condensing the oxo-compound with that containing a reactive SH- group and treating with the p-aminobenzenesulphonamide.  Any chemotherapeutically - active p - aminobenzenesulphonamide may be used as starting-material.  Advantageously, such compounds contain a heterocyclic substituent in the sulphonamido group.  Aliphatic, aromatic, alicyclic or heterocyclic aldehydes or a -keto-carboxylic acids are used as oxo - compounds. Advantageously, aliphatic aldehydes are used containing a small number of carbon atoms, e.g. formaldehyde or glyoxylic acid. Aliphatic, aromatic, alicyclic or heterocyclic compounds containing a reactive SH- group are used.  If aldehydes containing salt-forming groups or keto-carboxylic acids are used, other SH- compounds may be used, e.g. ethyl mercaptan, thiophenol, thioglycollic acid ethyl ester, thioglycollic acid anilide, or thio-acid such as thioacetic- and thiobenzoic acids. Advantageously, the p-aminobenzene sulphonamide, oxo-compound and SH- compound are reacted in presence of an organic solvent such as ethanol, methanol, dioxan or acetic acid, optionally in presence of water.  Salts are obtained from compounds carrying acid groups, e.g. by treating with organic bases, such as diethylamine, triethylamine or ethanolamine or with inorganic bases to obtain especially the sodium, calcium or ammonium salts, and in particular salts wherein the sulphonamido group resists salt-formation; salts with acids, e.g. hydrohalic acids are obtained from the final products of compounds carrying basic substituents.  Numerous examples are given. Specifications 550,040 and 553,164 are referred to.  The Specification as open to inspection under Sect. 91 includes treating (i) 2-(p-aminobenzenesulphonamido)-thiazole with aqueous formaldehyde and (a) thioglycollic acid, (b) thiosalicyclic acid, (c) thiolactic acid, and (d) b -thiolactic acid; and (ii) p-aminobenzenesulphonmethylamide with aqueous formaldehyde and thioglycollic acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 166,358. Taylor, A. R. April 15, 1920. Thermionic modulating systems and apparatus. -In a wireless telephone transmitter of the type in which a generating-valve V and a control valve V<1> are arranged in parallel, the choke E in the high-tension anode circuit, and a coil C in the microphone circuit, are wound upon the same core I. In the preferred construction, the core I forms a closed magnetic circuit A coil D in the filament-heating circuit may also be wound upon the same core. The coil C is so arranged that when the grid of valve V<1> is rendered positive by speech, an electromotive force is set up in coil E opposed to that of the battery HT, but when the grid is rendered negative an electromotive force is set up which augments that of the battery. The coil D is so wound that, when no modulation occurs, the core I is unmagnetized. In a modification, both the primary and secondary coils A, B of the microphone transformer are wound upon the core I. According to a further modification, the coil C is in series with the secondary winding B of the transformer, so that a regenerative effect is produced between the coil C and the choke E.

IPC: H04B1/22
Filed: 1917-07-27
Abstract: 117,686. Brown, D. W. July 27, 1917. Wireless telegraphy; wave detectors.-Greater sensitiveness is obtained in wireless reception by maintaining a locally-generated electric or electro-magnetic field around parts of the receiving circuits or apparatus. As shown in Fig. 2, a part of the aerial circuit is connected to a direct-current generator G or low-frequency alternator through choking-coils k and a resistance R. The choking-coils prevent the received oscillations from reaching the generator G, and the detector D is shielded from the locally-produced current by a condenser C, or a non-inductive resistance. A second condenser C may be arranged in the common wire of the aerial and local circuits. In the form shown in Fig. 3, the local generator G is connected across a spark gap s in the aerial, which gap is so adjusted that the local voltage alone is insufficient to break it down. The detector D may be placed in a secondary circuit B<2>, B<3>. The local generator G may be connected to condenser plates M, Fig. 4, enveloping the detector D. In another modification, shown in Fig. 5, part of the aerial is enclosed by, and insulated from, a conducting tube H which is connected to a local generator G<1>. The generator G connected to the aerial may also be connected to the tube H. This tube may be placed around part of a secondary circuit inductively coupled to the aerial circuit. The tubes H may be built up of a number of sections H<4> abutting end to end or connected externally by conductive strips or sleeves v, Fig. 8. The ends of the tube sections may have insulating plugs n, and the aerial wire may be formed in sections connected by sleeves r. The tube sections may be in halves with flanges to secure them round the aerial, and the insulating disks may also be formed in halves and may be notched to permit air circulation. A wire coiled round the aerial, and insulated therefrom, may replace the conducting tube H. The insulated tubes or coils form the subject-matter of Specification 120,356. In all forms, a switch S may be provided for disconnecting the detector circuits from the aerial, and substituting the transmission circuits.

Abstract: 1,134,135. Deep well pumps. A. G. BODINE. March 11, 1966, No. 10915/66. Heading F1R. In a deep well pump of the type described in Specification 593,197, well liquid which has passed through a sand filter 36<SP>1</SP> is recirculated under the control of a valve V via the annular space between the oscillating well tubing 12 and the pipe jacket 11 to the lower end of the tube 12 to dilute the well sand/liquid mixture in excessively sandy conditions. Flow of sand into the annular space is restricted by a sand barrier which in the form shown comprises a perforated closed landed jacket section 11<SP>1</SP>. In the Fig. 5 embodiment (not shown) a resilient sealing ring (98) is secured to the jacket and engages the end of the tubing 12 to restrict the flow of sand into the annulus but allows recirculation to the tube inlet. In Fig. 7 (not shown) the tube passes through a sealing bush (145) and a further barrier is provided at (170b). An inlet valve forming a sand barrier may be fitted to the jacket pipe 11 which encloses the end of the tube 12 Fig. 8 (not shown). In these latter embodiments holes are provided in the tubing 12 at suitable points for recirculating liquid. The holes may be controlled by valves (122 Fig. 6 not shown). Liquid may also be delivered between the well casing W and jacket pipe 11 to the bottom of the well.
