Abstract: 1,153,488. Tetrahydronaphthalene derivatives, and their use in the preparation of secosteroids. MERCK & CO. Inc. 24 Aug., 1966 [30 Aug., 1965], No. 37975/66. Headings C2C and C2U. Novel sulphonium salts of the formulµ (wherein R 1  is H, C 1-5  alkyl, alicyclic, aryl, alkaryl, aralkyl or heterocyclic; each R 2  is C 1-5  alkyl; and X is an organic or mineral acid anion) are prepared by reacting 1-vinyl-1- hydroxy - 6 - OR 1  - 1,2,3,4 - tetrahydronaphthalenes with thiourea or a dialkyl sulphide in the presence of a mineral or organic acid, and are converted into seco-steroids of the Formula (IV) by reaction with cyclic diones of the Formula (III) (wherein R 3  is H or C 1-5  alkyl; Z is -CH 2 - or -(CH 2 ) 2 -; R 4  is H when R 3  is H and/or when Z is -(CH 2 ) 2 -, and is H, CONH 2 , COO(C 1-5 - alkyl) which may be aryl substituted, or OCO- (C 1-5  alkyl) when R 3  is alkyl and Z is CH 2 ; and when R 4  is alkanoyloxy R 5  is H and the dotted line represents a double bond, and when R 4  is other than alkanoyloxy, R 5  is the same as R 4  and the dotted line represents a single bond). The seco-steroids may be ring closed with an acid to give the corresponding #<SP>1,3,5(10),8,14</SP>- steroids or-D-homo-steroids; selective catalytic hydrogenation of these at the #<SP>14</SP> double bond give the corresponding #<SP>1,3,5,(10,)8</SP>-steroids or -D-homo-steroids having a 14α-hydrogen atom (if R<SP>1</SP> is benzyl or substituted benzyl or if a 15-benzyloxycarbonyl or -substituted benzyloxycarbonyl substituent is present hydrogenolysis to the corresponding 3-ols or 15-carboxy compounds also occurs) which may in turn be reduced with potassium in liquid ammonia to the corresponding #<SP>1,3,5(10)</SP>-steroids or -D- homo-steroids of normal configuration i.e. 9α,8#,14α. In these steroid products a 15- amide or ester substituent may be hydrolysed to a 15-CO 2 H group, which may be used to resolve the steroid or may be removed by standard procedures.

Abstract: 1,014,649. Flame monitoring systems. ELECTRONICS CORPORATION of AMERICA. Oct. 8, 1962 [Oct. 9, 1961], No.38065/62. Heading G1A. A flame monitoring system includes a breakdown type discharge tube sensitive to ultra-violet radiation from the flame which tube is fed with a.c. at a frequency less than 25 c.p.s and an amplifier having a pass band including the a.c. frequency. The detector 22 which senses ultra-violet radiation from a main flame and a pilot flame is fed with a.c. from a capacitor 32. Capacitor 32 is charged from a transformer 38 and the voltage on the detector reaches a level at which avalanche breakdown occurs between the electrodes 26, 28 in response to bombardment of the detector by ultra-violet radiation somewhat less than 25 times per second. Pulses from the detector on breakdown are fed to a damped resonant circuit 48, 50 where it is converted to a low frequency (less than 25 c/s) sine wave signal which controls relay 120. The relay control circuit comprises bandpass amplifiers 60 and 62, the output of which is rectified and integrated on capacitor 108 and if ultra-violet radiation is being received, the tube 110 is cut off allowing tube 114 to conduct and energize relay 120. When the main and pilot burners use different fuel, it may be desirable to have a system responsive to both infra-red and ultra-violet radiation. In this case a PbS photoresistor 124 is included in the circuit.

Abstract: 1,087,364. Electric gas analysis; determining oxygen. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 7, 1966 [Sept. 7, 1965], No.38143/65. Headings G1B and G1N. The concentration of oxygen in the atmosphere, e.g. down a mine, is measured by catalysing the reduction of the oxygen by a gaseous reducing agent and measuring the heat produced by the reaction which gives an indication of the oxygen concentration. The transducer comprises a thermocouple whose hot junction is embedded in a catalyst and which is housed in a chamber 1, Fig. 1, to which an excess of a gaseous reducing agent, e.g. methanol, ethanol or ether, is also supplied, the gas being evaporated from a wick 6, e.g. of cotton wool, of which the end is immersed in a reservoir 8 of liquid reducing agent. The chamber is open to the atmosphere through an aperture 12 covered by a filter 11 of layers of wire mesh or sintered material. The inside of the chamber is covered by a layer 13 of absorbent paper which is provided with two apertures 15, 16 through which the vaporized reducing agent flows and the hot junction of the thermocouple projects. The thermocouple is formed of two wires 19, see also Figs. 2, 3 (not shown), of alloys of gold and palladium and platinum and iridium, joined together at (17), the wires, in the area of the join, being coiled and the coil (30) being coated first with a refractory material e.g. aluminium oxide, to form a small bead (31) and then with the catalyst (32), e.g. thoria and palladium mixture. In operation, the thermocouple is first connected to a battery (23), Fig.4 (not shown), through a two way switch (25), to initiate the reduction of the oxygen. The battery is then disconnected and the thermocouple is connected across a potentiometer (26), a voltmeter (22) measuring the voltage across the potentiometer and giving an indication of the oxygen concentration in the atmosphere.

Abstract: 1277149 Checking electric circuits by digital computer CANADIAN GENERAL ELECTRIC CO Ltd 17 Aug 1970 [18 Aug 1969] 39579/70 Heading G4A A method of conditioning the operation of a digital computer for checking a complicated electric circuit is disclosed wherein the computer scans its records relating to the various terminals of the circuit and prints out the circuit condition between terminals. This is to detect open and short circuits between terminals. All conductors having the same potential have a common identity so that the records can be sorted in a known manner from input records or cards to produce a subfield of equal potential, for example terminals A to H of Fig. 1. The computer then makes a first pass which determines the order of the terminals (see table in the description) i.e. the identity of each terminal and its branches &c. are checked. A second pass establishes continuity on the line A to D, a third pass establishes continuity of BE, a fourth BF, and a fifth CH, print out occurring after each pass to give the identity of the conductors connected to their terminals and information relating to the functions thereof. The computer may also be used to check short circuits by scanning the entire records to detect any terminal having conductors of different potential connected thereto (Fig. 2, not shown) which indicates a short circuit.

Abstract: 837,400. Spray carburetters. GENERAL MOTORS CORPORATION. Dec. 10, 1958 [Jan. 29, 1958], No. 39814/58. Class 7(3) The proportion of air flowing through a Venturi 14, the suction at which controls a fuel metering system 36 supplying fuel under pressure to individual. injection nozzles 26, is decreased as the engine temperature rises. The Venturi 14 is formed by an annular member 13, the central passage 40 of which contains a valve 42 controlled by a resilient bimetallic coil 48, Fig. 3. At low temperatures valve 42 is closed so that all the air flows through the annular Venturi 14 to set up a high suction which produces a rich mixture. As the temperature increases, the coil 48 opens the valve 42 to permit a portion of the air to by-pass Venturi 14 and reduces the mixture strength. The valve- 42 is offset so that increased air flow when the throttle valve 42 in the opening direction. A link 68 from the coil 48 operates a fast idle cam 58 co-operating with the throttle valve, stop screw 62. The valve 16 overlaps and fits into a recess 44 in the valve 42 when wide open.
