Abstract: The invention comprises testosterone esters of the general formula <FORM:0753793/IV(a)/1> where R is an aryl radical or a lower alkyl, alkoxy or halogen substitution product thereof, X is H or lower alkyl (1-6 carbon atoms) and n is 0, 1 or 2; and a process for their preparation by esterifying testosterone by a method normally used for esterifying hydroxylated steroids.  Specified methods are (1) treatment of testosterone with (a) the appropriate acid halide or anhydride, preferably in an inert solvent, e.g. benzene, tetrahydrofuran, and using an acid-binding agent, e.g. pyridine; (b) the appropriate free acid in an inert solvent, e.g. toluene, and using an acid catalyst, e.g. p-toluene sulphonic acid; (2) reaction of a 17-halogenated derivative of testosterone with the silver salt of the appropriate phenoxy acid.  In examples: (1) testosterone is refluxed with phenoxyacetic anhydride in benzene to yield testosterone phenoxyacetate; (2) testosterone in tetrahydrofuran is refluxed with p-chlorophenoxyacetyl chloride to yield testosterone p-chlorophenoxyacetate.  Similarly, using the appropriate acid chlorides, testosterone 2 : 4-dichlorophenoxyacetate, a  - phenoxybutyrate and b -phenoxypropionate are prepared.  Other esters listed are the p-methyl-, p-bromo-, p-methoxy-, o-chloro- and p-tert-butyl-phenoxyacetates, and the (-) and (+)-a -phenoxypropionates.ALSO:Pharmaceutical compositions for androgenic therapy comprises an androgenic agent consisting essentially of a testosterone ester of the general formula: <FORM:0753793/VI/1> (wherein R is an aryl radical or a lower alkyl, alkoxy or halogen substitution product thereof, X is H or lower alkyl, and n is O, 1 or 2) together with a non-toxic vehicle.  The esters may be formulated as an injectable suspension a) in aqueous media, incorporating a wetting agent; (b) in an anhydrous hydrophilic base e.g. polyethylene glycol; or (c) in an oleaginous vehicle, e.g. sesame oil containing aluminium monostearate and propyl paraben.  A typical aqueous injectable suspension incorporates dibasic sodium phosphate, monobasic potassium phosphate, polysorbate 80, sorbitan monolaurate, and thimerosal in addition to testosterone phenoxyacetates.  The esters may also be administered as ointments, tablets or suppositories, specified diluents being cetyl alcohol, glyceryl laurate, glyceryl monostearate, magnesium stearate, glycerine, propyl paraben, begamot, starch, gelatin, lactose, ol. theobroma, and alcohol.

Title: Method of stranding with a storage stranding machine
IPC: D07B3/00
Filed: 1967-05-04
Abstract: 1,136,057. Stranding cables. KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 4 May, 1967 [5 May, 1966], No. 20819/67. Heading D1T. The invention relates to the stranding of elements in which said elements are drawn from a stationary supply source and introduced into a rotating store, the stranding being effected by the rotation of the store about its longitudinal axis and of the kind in which, when the store is full, its direction of rotation is changed. The completed cable is then drawn out whilst fresh elements continue to be drawn in. This results in a reversal of lay at intervals. According to the invention the rotation of the store is speeded up just before reversing its direction of motion, and its initial reverse speed is higher than its ultimate reverse speed. This results in a reversal point as shown in Fig. 2 in which at the reversal point U the lay lengths in the region a1, a2 are short compared with the remaining lay lengths. The resulting deformation of the elements prevents them opening out.

Also in Division F4] Means for supplying heat to an apparatus converting the heat into mechanical energy (e.g. a hot gas engine) comprises a first container in which the heat is generated by an exothermic reaction between a liquid metal or metal mixture and a controlled close of a reacting medium supplied from a second container 17 through a communicating duct 18, the said first container incorporating a duct 31 through which the hot reacting materials are circulated by means such as an impeller 32 and wherein the heat is supplied to the said apparatus. Fig.1 shows an arrangement in which the working fluid of a hot gas engine (not indicated) circulates through a heat-exchanger 34 immersed in the reacting materials in the circulation duct 31. The reacting medium in the container 17 is supplied through line 18 to the duct 31 together with an inert gas from a container 23. Said gas passes through the reacting materials and forms a gas blanket in a space 14 above the liquid level in the duct 31. The remaining gas passes through a separator and cooler 28 into a line 26 from which it is returned by a pump 27 to the container 23. When the supply of reacting medium is cut off by closure of the valve 20, the continued flow of inert gas through the line 18 prevents back-flow into the line 18 of the liquid metal from container 15. Alternatively for the same purpose in an arrangement not using an inert gas, a check valve may be provided at the point 36. The container 15 is heated up on starting by electric heaters 35. In another arrangement (Fig.2), the working fluid of a hot gas engine (2-9) circulates through a heat-exchanger (11-13) immersed in a liquid heattransfer medium which is heated by being circulated through a heat-exchanger (43) in the duct 31.

Abstract: 724,875. Cooling dynamo-electric machines. GENERAL ELECTRIC CO. Aug. 4, 1953 [Aug. 1, 1952], No. 21488/53. Class 35. Stator or rotor slot conductors have their sides cut away to provide longitudinal passages between the slot insulation and the conductors while radial passages in the teeth conduct fluid from the longitudinal passages to the air gap. As shown, the conductors have recesses 20, 21 at intervals in their sides to enable the hydrogen flowing axially along recesses 13 to pass radially and then tangentially into ducts 16 or 17 formed in the teeth, the gas then traversing the air gap and radial ducts in the stator core to reach a cooler in the upper part of the machine, the gas then being re-circulated. Near the centre (axially) of the core some ducts in the teeth extend further inward radially to communicate, with gas passing along ducts 27 at the bottoms of the conductor slots. Such gas passes first radially and then can enter the conductor slots at intermediate points in their radial depth, and flow axially along conductors before passing through other tooth ducts to the air gap. To achieve this the deeper tooth ducts are blocked at the air gap end but have intermediate holes communicating with conductor slots. The conductor and slot arrangement shown for the rotor could be applied alternatively or additionally to the stator.
