Title: 17ª‰-hydroxy-17-alkynyl steroids and their preparation
Inventor: ELLIS BERNARD
IPC: C07J1/00
Filed: 1957-05-21
Abstract: The invention comprises 17b -hydroxy-17 a -alkynyl steroids of the 3:5-cycloandrostane series wherein the alkynyl group has the formula -C­CR, R being an alkyl group containing at most 4 carbon atoms; and a method for the preparation of 17b -hydroxy-17a -alkynyl steroids of the 4-androstene, 5-androstene and 3:5-cycloandrostane series, the alkynyl group being defined as above, in which a corresponding 17-oxo steroid is reacted with the appropriate alkynyl magnesium halide and the desired steroid is subsequently regenerated from the complex so formed.  The reaction may conveniently be effected by adding a solution of the substituted 17-oxo-steroid in a solvent such as tetrahydrofuran to an excess of an alkynyl magnesium bromide or iodide in a similar solvent and then refluxing or allowing to stand at room temperature for several hours.  The complex may be decomposed by the addition of aqueous ammonium chloride and the product isolated with ether.  Oxo groups present in the steroid molecule may be protected by ketal or enol ether formation and subsequently regenerated.  Examples describe the conversion of dehydroiso-androsterone to 17a -(prop-1-ynyl)-androst-5-ene-3 b  : 17b - diol and the corresponding but-1-ynyl, pent-1-ynyl and hex-1-ynyl compounds, of 6 b -hydroxy-3:5-cycloandrostan-17-one to 17a -(prop-1-ynyl)-3:5-cycloandrostan-6b :17b -diol and the corresponding but-1-ynyl and pent-1-ynyl compounds, of 6-methyldehydroisoandrosterone acetate to 6-methyl-17 a -(prop-1-ynyl)-androst-5-ene- 3b  :17b -diol,of the 3 enol ethyl ether derived from androst-4-ene-3:17-dione or of the 3:3-ethylenedioxy derivative thereof to 17b -hydroxy-17a -(prop-1-ynyl)-androst-4-en-3-one, and of the 3:3-ethylendioxy derivative of 6a -methylandrost-4-ene-3:17-dione to 17a -(prop-1-ynyl)-17b -hydroxy-6a -methylandrost-4-en-3-one and the corresponding but-1-ynyl compound.  Reference is also made to the application of the process of the invention to 11-oxygenated androst-4-ene-3:17-diones.  The Provisional Specification describes steroids of the basic structure <FORM:0842678/IV(b)/1> (wherein R is an alkyl group containing at most 4 carbon atoms), and their preparation and, in addition to the above subject-matter, describes specifically (1) certain 19-nor-androst-4-en-3-ones of this formula which form part of the subject-matter of Specification 842,676; and (2) 17a -(pent-1-ynyl)-oestra-1:3:5(10)-triene-3:17 b -diol. Reference is also made to the application of the above process to acylates of the last mentioned compound, to 1-methyl-3-hydroxy-oestra-1:3:5(10)-trien-17-one and -1:3:5(10):6-tetraen-17-one and to 19-nor-androst-4-ene-3:17-dione and enol ethers thereof.

Abstract: 1,171,412. Selective signalling. STANDARD TELEPHONES & CABLES Ltd. 4 April, 1968, No. 16157/68. Heading G4H. An 11 x 15 dot-mosaic system for displaying or printing a line of characters, the system being of the type in which by means of either a simple non- interlaced C.R.T. raster or a row (e.g. 880) of dot recording heads arranged transversely to the direction of paper feed in an electrographic printer, first the top row of dots for all the characters in the line is disdisplayed or printed, secondly the second row of dots for the complete line is displayed or printed, and so on until the whole line has been displayed or printed, is characterized in that the dot control signals for the entire line are generated by the repeated use of a single matrix of storage elements (e.g. ferrite cores), the generation of a single row of dots, for example row 3, labelled C in Fig. 2A, occurring as follows: read-in first character by energizing the appropriate one of a set of character leads; read-out third row of dots of first character; clear matrix and read-in second character; read-out third row of dots of second character, and so on until the whole line of characters have been read in. The character matrix has an additional row of elements, labelled P, over and above those required to generate the dots of a character. When a character lead is energized, in addition to setting storage elements corresponding to its shape, a single element in row P is set to indicate the width of the character, and the system is so arranged that when a row of the character is read-out row P is also read-out and when the set core is detected read-out is stopped. In this way characters are allotted a space corresponding to their width. The Specification discusses how to obtain italic and bold fonts and how justification, using a plurality of different width spaces, can be achieved, but no circuit drawings are given.

Title: A telephone system with two-party connections
IPC: H04Q5/24
Filed: 1953-06-12
Abstract: 749,120. Exchange systems. LICENTIA PATENT - VERWALTUNGS - GES. June 12, 1953 [June 16, 1952], No. 16221/53. Class 40 (4). Two subscribers' lines are branched from a common switching-installation on an exchange line, and while one subscriber is engaged in a call the other is disconnected from the exchange line by means of a relay which in operating breaks its own operating circuit and holds itself operated by magnetic remanence. As shown in Fig. 1, the common switching- installation Um comprises two relays U1, U2, each having an operating winding 1/2 and a release winding 3/4. When one subscriber, say Tn1, lifts his receiver, a relay R at the exchange is operated and brings up a relay T (not shown) which extends the line AL to the feed relays A, B. These are of lower resistance than relay R, and the relay U1 associated with the calling subscriber Tn1 is now operated. Relay U1 completes the line loop for Tn1 disconnects the other subscriber Tn2, and breaks its own energizing circuit, holding its armature attracted thereafter by magnetic remanence. The release winding 3/4 is in series with a high resistance, which may be of the non-linear type, and does not receive sufficient current either to release the relay or to weaken appreciably the supply to the telephone transmitter of subscriber Tn1. When Tnl hangs up, relay T falls back at the exchange and the release winding 3/4 responds to the re-application of negative potential to the b-wire so that relay U1 falls back. In modifications, Figs. 2 and 4 (not shown), the release winding is connected to a line wire in series with a condenser and is energized by its charging or discharging at the end of a call. In a further modification, Fig. 3 (not shown), no separate release winding is provided, the relay being released by the passage of current through the operating winding in the reverse direction.
