Patent GB-935334-A (GB)
Title: New anabolic steroids and the preparation thereof
IPC: C07J75/00
Filed: 1961-07-12
Abstract: The invention comprises 16-methylene-17a -methyl-5-androstene-3b ,17b -diol, 16-methylene-17a -methyl-testosterone and the corresponding 1-dehydro compound, and 16-methylene-17a -methyl-testosterone-3-oxime and the corresponding 1-dehydro compound, and a process that comprises treating 16-methylene-5-androsten-3b -ol-20-one with an alkali metal methyl or a methyl magnesium halide to form 16-methylene-17a -methyl-5-androstene-3b ,17b -diol, if desired, mildly oxidising this compound to form 16-methylene-17a -methyltestosterone and, if desired, dehydrogenating this compound microbiologically or chemically in the 1,2-position and/or converting the 3-keto-group into a 3-oxime group.  The oxidation may be carried out using the Oppenauer method or by the action of a culture of the microorganism Flavobacterium dehydrogenans.  If a culture of the microorganism Corynebacterium simplex is used for the oxidation, dehydrogenation in the 1,2-position also takes place to form 16-methylene-1-dehydro- 17a -methyl-testosterone in one step.  The dehydrogenation step may be carried out with selenium dioxide or 2,3-dichloro-5,6-dicyano-benzoquinone, or by means of a culture of any of the microorganisms Bacillus sphaericus, Fusarium solani, Corynebacterium simplex, Alternaria sp., Mycobacterium smegmatis, Calonectria decora, Mycobacterium lacticola, Ophiobolus sp., Alcaligenes sp., Didymella lycopersici, Protaminobacter sp., Septomyxa affinis, Nocardia sp., Cylindrocarpon radicicola, Streptomyes lavendulae, and Bacillus cyclooxydans.  In the above process it is possible to convert the 3b -ol-5-ene system into a 3-keto-4-ene system, and to introduce the 1,2-double bond before the reaction with the alkali metal methyl or methyl magnesium halide. Therapeutic compositions having anabolic activity contain as the active ingredient a 16-methylene-steroid compound detailed above. The composition may be in the form of a pill, tablet, dragee, suppository, emulsion or injectable solution. 16-Methylene-5-androsten-3b -ol-20-one is prepared by a Mannich condensation with 5-androsten-3b -ol-20-one to form 16-dimethylaminomethyl- 5-androsten-3b -ol-20-one which is then decomposed by steam distillation.

Title: Improvements in or relating to semi-conductor devices
IPC: H01L23/02
Filed: 1958-08-13
Abstract: 893,493. Semi-conductor rectifiers. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and LANGRIDGE, A. Aug. 13, 1959 [Aug. 13, 1958], No. 25991/58. Class 37. In a semi-conductor device of the kind in which a crystal element is mounted on a heatdissipating metal base to which a metal housing is welded to form an hermetically sealed enclosure, a band of a metal having a coefficient of thermal conductivity lower than that of the base is fixed in the region of its inward edge to the base, and the housing is welded to this band, which may be a washer of the same metal as the housing. This reduces the amount of heat conducted by the base to the crystal during the welding operation. In the diode shown, the inner periphery of a steel washer 17 is attached by silver soldering to the central upstanding spigot portion of a cylindrical base 12 of copper, after which the base and a steel housing 14 are nickel-plated. A germanium crystal 11 comprising a PN junction, is mounted on the base, a conductor 13 is connected to the crystal, and the housing 14 is placed in position on the base, the conductor 13 passing through a glass-to-metal seal 15 and being sealed by a top cap 16. A beading on the underside of a flange of the housing is then resistance welded to the steel washer 17, the base being subsequently machined, if necessary, to eliminate distortion due to differential expansion between base and washer. To minimize this distortion, particularly in silicon diodes where the heat generated in operation may be considerable, the inner upper edge of the washer may be chamfered to form, with the spigot portion of the base, a circular groove to receive the solder; also an annular groove may be provided in the base around the spigot to trap excess solder.

Abstract: 1388678 Making collapsible containers VICTOR METAL PRODUCTS CORP 6 June 1972 [14 Oct 1971] 26312/72 Heading B3A [Also in Division B8] A method of making a collapsible container from a strip of sheet material comprises wrapping the material 15 upon mandrel means, severing the strip to provide overlapping margins, sealing the margins to form a fluid tight body, pre-forming one end of the body into equally, spaced flutes, folding the fluted end beyond the end of the mandrel means, applying an outsert 56 over at least a portion of the folded end of the container body and adhering the outsert to the body. A plurality of mandrels 13 are mounted on a plate 1, which is rotated step-by-step to carry the mandrels to a succession of work stations. The strip is of metal, plastics, waxed paper or plastic coated metal, e.g. aluminium, lead or lead coated with polyethylene, and it may be decorated as at 17 while still flat. The strip is held on the mandrel 13 as it rotates by vacuum means or it may be held in position by rollers. The strip is cut by shears 22 and the overlapping margins are sealed by induction heating. If necessary, bands of adhesive are placed on the strip at suitable intervals. The seamed body is indexed to a pre-form work station, where a chamber 35 is placed over one of its ends. Pressure fluid is fed to an annular space 40 and passing through openings 44 it acts on an elastomer ring 41 to form flutes in the end of the body in co-operation with flutes (27), Fig. 3 (not shown), formed in a spindle 25, which is slidably mounted in the end of the mandrel 13. The chamber 35 is then withdrawn and the pre-formed container is advanced to a fold-forming station. The spindle 25 is retracted and a pin 31 now extends beyond the spindle into the reduced portion 45 of the body. The mandrel is now rotated at about 400 r.p.m. and rollers 48, 49, Fig. 8, are brought into contact with the fluted end of the body to form a shoulder 28, a step 56a and a neck 51. The rollers 48, 49 are freely mounted on shafts 53, 54 respectively and are advanced hydraulically into contact with the body. At the next station excess material is trimmed from the neck 51, if necessary, and at the following station the outsert 56 is fitted over the end of the body. The plate 11 is indexed again and the outsert is heat sealed to the body. At the following stations the body is cooled, a cap (59), Fig. 11 (not shown), is threaded on to the end of the outsert and the container body is unloaded. The mandrels may be of non-circular cross-section or tapered to form bodies of different cross-sections and shapes, Figs. 12-13 (not shown). The outsert may comprise an externally threaded tubular member, which is fixed to the neck 51 only or a part-spherical cap may be fitted to the outsert. In a further embodiment, Fig. 16 (not shown), the outsert is provided with an outer cylindrical skirt (63) and a flanged closure member (64) gives an ornamental cylindrical shape to the container end.
