Abstract: 1,019,315. Inverting. INTERMETALL GESELLSCHAFT FUR METALLURGIE UND ELEKTRONIC m.b.H. Nov. 20, 1962 [Nov. 20, 1961], No. 43935/62. Heading H2F. A three-phase inverter with no output transformer providing a variable frequency output has a six-stage ring counter driven by a relaxation oscillator. Each stage comprises four layer diodes V 1  &c., diodes D v , coupling capacitors C v  and load resistors R R1  &c. The relaxation oscillator has a four-layer diode V K , and the frequency is controlled by a variable resistor. Three transistors Tr R , Trs, Tr T  are each switched on when any one of three of the ring stages is on. For example:- Tr R  is on when either V 1 , V 2  or V 3  is on; and Trs is on when either V 3 , V 4  or V 5  is on. Thus V 3 , V 5  and V 1  have their load resistors formed of two parallel resistors, so that they can control two transistors. Each transistor Tr R  &c. controls a pair of output transistors, only one pair E TO , E TU  being shown. One output terminal is T. In Fig. 5 (not shown) a similar ring is used, but each stage controls only two of the transistors Tr R . Alternate transistors are the output transistors, while the other alternate transistors drive an opposite polarity type output transistor. The two circuits give different output waveforms (Figs. 2 and 3, not shown), the first giving a square wave and the second giving square pulses with a zero voltage period between successive positive and negative pulses.

In the illustrated embodiment the first tubular member 23 has three female locking elements each comprising a pair of spaced bars 24a each with projections 25 defining a groove 26, and the second tubular member has a set of three male locking ribs 35 and a set of three male locking ribs 36, each rib 35 or 36 having two grooves 37, 38. The first member 23 may be inserted into the second such that ribs 36 enter the spaces 33 between the bars 24a, in which case one bar of each pair hits a stop 40 on the second member and the grooves 26 are aligned with grooves 37, or such that the ribs 35 enter the spaces 33, in which case the bars 24a hit stops 39 and the grooves 26 align with grooves 38, the tyre support rim formed by the members 23, 34 then being of smaller width than when the bars 24a hit stops 40. The ring 28 is retained on the member 23 by virtue of a stop 32 which prevents complete withdrawal of the projections 27 from the grooves 26. The casing 6 serves to protect the tyre and tread band 5 when heat is applied from the exterior to vulcanize bonding material 7 to bond the band 5 to the tyre.

Abstract: The invention comprises steroids of the formulae <FORM:1062498/C2/1> wherein R1 is hydrogen or the aryl radical of a hydrocarbon carboxylic acid of less than 12 carbon atoms which may be substituted; R2 is hydrogen, or alkyl, alkenyl or alkynyl of at most 8 carbon atoms; Z is hydrogen, methyl, chlorine or fluorine; Y is a double bond or a saturated linkage between C-1 and C-2; and X is an alkyl group of at most 4 carbon atoms. They may be prepared by catalytic hydrogenation of a 19-(methylene or lower alkylidene)-D 4-10a -androsten-17b -ol-3-one to give the corresponding 19-lower alkyl-5b ,10a -androstan-17b -ol-3-one which, when required, is then subjected to the following processes.  Bromination and dehydrobromination yields 19-lower alkyl-D 4-10a -androsten-17b -ol-3-ones, these may be converted to the D 5-3-ketols, these to the 17-ones by oxidation, these with alkyl magnesium halides or alkali metal alkynes give the corresponding 17a -alkyl or alkynyl-17b -hydroxy compounds and these on hydrolysis give the 19 - alkyl - 17a - alkyl or alkynyl - D 4 - 10a -androsten-17b -ol-3-ones. The D 5-3-ketols with organic peracids give 5a ,6a -oxido compounds and these may be reacted with methyl Grignard reagents followed by treatment with a mineral acid and then with thionyl chloride in pyridine at a low temperature to give 6b -methyl-D 4-3-ones, which are isomerized to the 6a -methyl compounds by treatment with an alkali metal hydroxide; or the oxido compounds may be treated with hydrogen chloride to give the 6a -chloro-D 4-3-ones, or with hydrogen fluoride followed by treatment with hydrogen chloride to give the 6a -fluoro-D 4-3-ones. Reaction of 3-enol ethers of the 6-unsubstituted-D 4-3-ones with an N-chloroamide or -imide gives the 6b -chloro-D 4-3-ones, while reaction with perchloryl fluoride gives the 6b -fluoro-D 4-3-ones. Treatment of the enol ethers with 1 mol of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone in the presence of an acid catalyst gives the corresponding D 4,6-3-ones, while treatment of the D 4-3-ones with the quinone gives the D 1,4-3-ones.  These or the D 4,6-compounds give the D 1,4,6-3-ones on further treatment with the quinone. 17a -alkynyl products are converted to the corresponding 17a -alkenes by catalytic hydrogenation.  The 19-lower alkyl - 5b ,10a  - androstan - 17b  - ol - 3-ones are prepared as indicated above, the bromination and dehydrobromination step being omitted.  17-Esters are prepared by standard methods.  The steroids of the invention, which are stated to have anabolic-androgenic properties and anti-estrogenic activity, may be made up into pharmaceutical compositions with suitable carriers.

A stainless steel tube containing carbide elements sealed by sodium, Fig. 1 (not shown) has eddy currents induced therein by a first coil which are detected by coil 2 forming part of a Hartley oscillator 1. As the tube is moved through coil 2 variations in the grid voltage of the Hartley oscillator tube, proportional to the amplitude of the eddy currents, are applied via differential amplifier 5 to the X inputs of a twochannel recorder 3 and a recorder 4. Simultaneously variations in oscillator frequency are applied via frequency to voltage convertor 6 to the Y inputs of the two recorders. Examination of the three curves of the recorders, details of which curves are discussed with reference to Figs. 3, 4, 5, 6 (not shown) enable flaws to be detected and assessed.
