Title: Steroid compounds and their preparation
IPC: C07J5/00
Filed: 1957-01-24
Abstract: The invention comprises steroid compounds of the general formula: <FORM:0845116/IV(b)/1> wherein R represents a hydrogen atom or a C2-12 organic carboxylic acyl group, R1 represents a hydroxy or keto group and X represents a chlorine or fluorine atom, and a process for the preparation of steroid compounds of the general formula: <FORM:0845116/IV(b)/2> wherein R11 represents a C1-11 organic group, by reacting the corresponding 9,11 b -oxido compounds with a source of hydrogen chloride or hydrogen fluoride, and optionally oxidising the steroid compound thus produced to the corresponding 11-keto steroid compounds.  The corresponding free 21-hydroxy compounds are prepared by hydrolysing the compounds having the -OCOR11 group at the 21-position.  The 11-keto-21-hydroxy compounds are also obtainable by oxidising the 11 b ,21-dihydroxy compounds.  The above processes may be modified in that the 9,11 b -oxido reactants are prepared by a process described in the Specification 845,117.  The organic acyl group may be derived from acids in the series formic to octanoic acids, cyclopentane carboxylic, cyclopentylpropionic, trimethylacetic, phenylacetic, benzoic, toluic, oxalic p-aminobenzoic, hydrocinnamic, hemisuccinic and b ,b -dimethylglutaric acids.  The acids may contain substituents such as halogen, alkyld an alkoxy substituents.  In the examples the following compounds are prepared:-12a -fluoro-4-prenene-11b , 21-diol-3,20-dione and the 21-acetate thereof, 12a -fluoro-4-pregnene-21-ol-3,11, 20-trione and the 21-acetate thereof. Other 21-acylates may be prepared by esterifying the free 12a -fluoro-21-hydroxy compounds of the examples.ALSO:A therapeutic composition comprises an inert pharmaceutical carrier and, as the active ingredient, a steroid compound of the general formula: <FORM:0845116/VI/1> wherein R represents a hydrogen atom or a C2-12 organic carboxylic acyl group, R1 represents a keto or hydroxy group, and X represents a chlorine or fluorine atom.  The carrier may be a liquid or solid.  Thus the composition may be in the form of a powder, tablet, capsule or other dosage form using, for example, starch, sugar or talc as the diluent, or a solution for parenteral solution using, for example, water or an oil as the diluent.  In addition to the active ingredient and water, the composition may contain suspending agents such as sodium p  carboxymethylcellulose, methyl cellulose, gelatin and various solubilizing or dispersing agents such as lecithin, In an example a topical ointment is prepared containing 12 a -fluoro-4-pregnene-11 b , 21-diol-3, 20-dione 21-acetate, zinc stearate, propylene glycol, carbowax and distilled water. Specification 845,117 is referred to.

Title: Improvements in Apparatus for Treating Photographic Film Tape.
Inventor: THOMPSON FREDERICK BENJAMIN
IPC: G03D3/13
Filed: 1918-02-15
Abstract: 123,168. Thompson, F. B. Feb. 15, 1918. Apparatus for successive treatment of long films.-In apparatus for developing, fixing, washing, and drying long strips of photographic film, the film is drawn from one of a pair of casings 82, 83, Fig. 1, and, after passing round idle rollers 84, 85, 86, is led successively round rollers mounted on a series of upper shafts 7 and lower shafts 10 disposed in tanks 1, 2, 3, 4. The rollers on each of the upper shafts 7 rotate freely, but those on the lower shafts 10 are driven at a variable speed by bevel gearing. On leaving each tank, the film passes over a spring-pressed tensioning-roller 21 co-acting with a roller 26 arranged to remove surplus liquid from the film. The film and its supporting-means are adapted to be raised from and lowered into the tanks by cables 79 connected to a windlass 80. During its passage from the last tank 4 to the drying-chamber 5, Fig. 2, the film is engaged by weighted rollers 37, 40 suspended in loops of the film. As it passes through the drying-chamber 5, the film travels round upper and lower rollers arranged similarly to those in the tanks and round additional guide-rollers 42, 43 disposed so as to cause the film to move in close proximity to perforated walls 46, through which warm dry air passes. The air is caused to pass through the drying-chamber in the opposite direction to that in which the film travels. The driven lower rollers in the drying-chamber are circumferentially grooved and are provided with pivoted stripping- fingers to prevent improper adhesion of the film. In order to compensate for the shrinkage of the film as it dries, the driven rollers in the drying- chamber are made of successively decreasing diameters. On leaving the drying-chamber, the film passes over a feed-roller 50 adapted to be driven at varying speeds, so as to ensure correct tension on the film, and it is then led to one of a pair of frictionally-driven take-up reels 52, 56.

Patent GB-370090-A (GB)
Title: Improvements in change speed gears
IPC: F16H3/66
Filed: 1931-01-30
Abstract: 370,090. Variable - speed epicyclic gearing. GESSNER, E. A., 4, Wettinerstrasse, Aue, Erzgebirge, Germany. Jan. 30, 1931, No. 3029. [Class 80 (ii).] Variable speed gearing comprises bevel gears 5 the speeds of which on their axes are varied by a gear or gears engaging anchored elements both inside and outside the pitch cone A B, C D of the gears 5. In continuously-variable gearing, shown in Fig. 1, the speed is varied by sliding friction rollers 7 radially upon a spider 4 which supports the main gears 5. The spider 4 is fast on a driving-shaft 1 and the rollers 7 engage the face of a non-rotary disc 17 pressed axially by a spring 19 adjustable from a hand-wheel 18. The driven element is a pulley 2 secured to a revoluble drum 20 loose on the shaft 1 and gaving two gear rings 21, 22 adapted to be enmeshed alternatively with the main bevel wheels 5. The speed ratio is controlled from a hand-wheel 11 through a screwed tube 12 connected by toggle links 9 so as to move the rollers 7 in unison. When the engagement of the friction elements 7, 17 is on the lines A B, C D, the pulley 2 is not driven. As the rollers are moved outwards or inwards, the speed of the pulley increases forwardly or backwardly, respectively. On moving the drum 20 and the pulley 2 to the left by way of a control rod 25, a different range of speeds is imparted to the pulley. An arrangement is described by which the disc 17 is driven at a constant speed to effect another range of speeds of the pulley 2. In an arrangement variable step by step shown in Fig. 5, trains of bevel gears 35, 36 take the place of the disc and roller gearing of Fig. 1. Driving and driven shafts 1, 2 are in line, the drum 20 sliding on the latter. The nested gears 36 are alternatively braked. When gear 36a is braked, there is no drive. When gears 36b, 36c are braked, increasing forward speeds result. When gear 36r is braked, the drive is reversed. These gears are connected by sleeves to drums 45 which are braked selectively by sliding a sleeve 49 upon a fixed rod 54 from a pedal 51. Each drum is encircled by a band brake 46, Fig. 6, with a control arm 48 resting on the sleeve 49. The sleeve 49 has a doubly-coned swell 50, Fig. 7, which slides under an arm 48 to apply the corresponding brake. The sleeve 49 is locked by the arm 48 engaging a notch 50a in the swell 50. An arrangement is described with toothed gear pairs instead of the brakes through which power may be transmitted alternatively when the drum 20 is temporarily locked against rotation, instead of being itself the driven member.

Abstract: 640,966. Making window-frames. BECKETT, LAYCOCK, & WATKINSON, Ltd. Feb. 3, 1948, No. 3191. [Classes 83 (ii) and 83 (iv)] [Also in Group X] Angular bending.- In glazing frames, e.g. for vehicles, comprising a channel- or anglesection metal strip secured around the edge of the aperture to be glazed and wherein the glass is secured by a rubber or similar removable packing strip, the strip is so formed that it may be bent or curved to the shape of the aperture. In a channelsection strip, Figs. 1-3 and 6, wherein one side wall 21 of the channel is higher than the other 22, the higher side is slotted from its free edge 25 towards the base 23, e.g. with downwardlyconverging slots 24 terminating in round holes 26. Fig. 3 shows how the strip can then be curved without distortion of the side wall 21. The height of the side wall 22 is insufficient to require slotting to prevent distortion. Fig. 6 shows how the channel-section strip is secured around the edge of the aperture in the panelling 20 to be glazed. A deep inverted channel C for securing the strip to the panelling may be formed as shown at 27 ... 30 in Fig. 2, and the part 29 thereof may be perforated at 31 to facilitate bending. In other cases, e.g. when the frame is secured direct to the wooden framework, as in Fig. 10, the deep inverted channel is omitted. Angle-section strips are similarly slotted along the vertical limb of the angle, e.g. as shown at 64, Fig. 16. The vertical limb of the angle-section strip and the higher vertical side of the channel-section strip can be provided with a plastic covering 32 which serves as a cushioned seating for one face of the pane 33, the other face and edge of the pane being engaged by the rubber packing strip 34. In Fig. 11, the packing strip itself is formed with an extension 47, 48 embracing the slotted side wall.
