Title: Improvements in or relating to heterocyclic sulphonyl-urea compounds and pharmaceutical compositions containing them
IPC: C07D295/28
Filed: 1961-08-21
Abstract: The invention comprises compounds of the formula <FORM:0917089/IV (b)/1> and pharmacologically acceptable acid addition salts thereof, wherein R is a C1-4 alkyl group and <FORM:0917089/IV (b)/2> is a saturated heterocyclic amino radical having from 5 to 9 ring atoms, Z being a polymethylene, oxapolymethylene, thiapolymethyllene or azapolymethylene radical, which may bear one or more alkyl substituents, and their preparation by reacting an alkanoylbenzenesulphonyl urethane with an N-amino-heterocyclic amine H2N.N=Z.  Preferably the group -N=Z is a piperidino, pyrrolidino, morpholino or hexamethyleneimino radical.  Alkanoylbenzenesulphonyl urethanes used as starting materials are made by treating an alkanoylbenzenesulphonamide with ethyl chlorocarbonate in the presence of an alkalimetal carbonate.  The alkanoylbenzenesulphonamide, RCO.C6H4.SO2NH2, is suitably prepared by treating an aminophenyl alkyl ketone with nitrous acid, reacting the resulting diazonium salt with sulphur dioxide and cupric chloride to give an alkanoylbenzenesulphonyl chloride and treating with ammonia. N-Amino heterocyclic compounds, H2N.N =Z, used as starting materials are made by nitrosating the heterocyclic base with nitrous acid and reducing the resulting N-nitrosoheterocyclic amine ON.N=Z, e.g. with lithium aluminium hydride or zinc and acetic acid.  When piperazine is the heterocyclic amine, the preferred starting material is 1-benzylpiperazine, which gives rise to the corresponding 1-amino-4-benzyl-piperazine and to N-(alkanoylbenzenesulphonyl) - N1 - (41 - benzylpiperazino)-ureas, from which the benzyl group may be removed by hydrogenation.  Pharmaceutical preparations for oral treatment of diabetes comprise the sulphonyl ureas of the invention or salts thereof such as the hydrochloride, sulphate, hydrobromide, phosphate, tartrate, acetate, citrate, succinate, maleate, benzoate or salicylate, together with a pharmaceutical carrier.  The preparations suitably take the form of capsules, tablets, powders, pills, aqueous suspensions or solutions or suspensions or solutions in edible oils.

Title: Improvements in or relating to electric switches of the type wherein the make and break contact elements are arranged to be separated beneath the surface of a liquid
IPC: H01H33/57
Filed: 1931-10-31
Abstract: 378,269. High-tension switches. SIEMENS SCHUCKERTWERKE AKT., GES., Siemensstadt, Berlin. Oct. 31, 1931, No. 30199. Convention date, Dec. 19, 1930. [Class 38 (v).] In an "expansion" switch as described in Specification 354,890 loss of switching liquid is avoided by subjecting the liquid and gas expelled at break to a centrifugal separating movement, the energy being furnished by the arc. In the arrangement shown in Fig. 1, the container in which is located the fixed switching contact 4 and the switching liquid 8 has fixed upon it, in the form of a lid, an annular chamber 5. This chamber has an outlet passage for the movable plug contact 6 and an annular passage 7 through which the liquid and gases discharged at break are whirled centrifugally to cause the liquid to settle on the walls of the chamber so that it may run back to the container through the pipe 10. The gases escape to the atmosphere through pipes 9 which have a streamlined contour so as to produce a minimum resistance to the whirling gases. In a modification, Fig. 2, the circuit is broken within an inner chamber with a cover structure 14, 17 held down resiliently by means of a rubber washer 16. The inner cover is raised slightly by the pressure developed at break and the gases, mixed with liquid, are forced through inclined passages in the portion 17 so as to set the outer liquid in rotation and by centrifugal action cause the discharge liquid to settle.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1931-11-04
Abstract: 391,507. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and BAKER, G. T., Blackbrook, Caerphilly, Glamorgan. Nov. 4, 1931, No. 30587. [Class 40 (iv).] In a bi-directional final selector which has access to individual subscribers' lines over one set of wipers and to P.B.X. lines over a second set of wipers, a preliminary digit to which the 'selector responds and then drops back determines the set of wipers to be used and modifies the circuits-to enable P.B.X. hunting to take place when necessary. The final selector described is adapted for use by a toll operator for extending calls to busy lines. Calls to individual subscribers. The preliminary digit, in this case 4, operates the vertical magnet VM, and when dialling relay C falls back the release magnet ZM operates over vertical wiper VB to restore the selector. Relay DA, which was previously short-circuited at off-normal contacts N3, now energizes, and the wanted line is selected in response to two further digits. Test and switching relay H is connected to the test wiper on the relapse of change-over relay E and energizes if the line is idle. To ring, the operator presses a key which grounds the negative line wire and thus energizes a differential relay OC in the line circuit, whereupon ring-trip relay F which operated upon seizure of the selector is released by 'short-circuiting and closes the ringing circuit, the connection being completed in the usual manner. If the wanted line is busy, relay G energizes and sends back a busy signal. To break in, the operator presses her key to energize relay OC which in this case connects up relay CN to close an auxiliary talking circuit. Relay CN locks over the test wiper and relay E re-operates. If the wanted subscriber, wishes to accept the call, he releases the existing connection, relay CN falls back and relay H energizes and completes the fresh connection. P.B.X. calls. After the receipt of the preliminary digit, in this case 5, wiper-switching relay WS energizes over the vertical wiper VB and connects up the release magnet ZM to restore the selector. Relay DA energizes and the selector responds to two further digits. The bank P.B.X. in which all the lines of a group except the last are marked by. ground is provided with two wipers which engage adjacent terminals simultaneously. If the first line of the selected group is busy, on the relapse of dialling relay C, relay HS energizes over the leading wiper, locks and closes a fresh circuit for the rotary magnet RM, which interacts with relay E to step the wipers over the'group. When an idle line is found, test and switching relay H energizes and ringing takes place under control of the operator. If all the lines are busy, relay HS falls back on the last line and relay G energizes to give a busy signal. When a special number is dialled to call a particular P.B.X. line, e.g. a night service line, relay HS is short-circuited over the two P.B.X. wipers when relay C falls back and consequently hunting cannot take place.
