For the study of aerosol filtration an aerosol emitter device comprises a reservoir for liquid to be vaporized, a vaporization chamber traversed by gas under pressure, a movable wire for conveying liquid particles and means for heating the wire to vaporize the liquid particles before entrainment thereof by the gas under pressure. In Fig. 1 a gas inlet tube 17 and aerosol outlet tube 18 communicate with vaporizing chamber 11. A wire 6, which may be nickel chrome, movable by means of variable speed motor 16 collects a layer of liquid, such as an indigo suspension, on its passage through reservoir 2, carries the liquid to vaporizing chamber 11 where the wire is heated and the liquid vaporized. The vaporized liquid is then entrained through the tube 18 by a pressurized gas. The portion of wire in the chamber 11 may be either heated indirectly by means of resistance heating element (Fig. 2 not shown) surrounding and spaced from the wire 6 and energized from a potential source, or directly (not illustrated) by connecting the potential source to two points on the wire 6 by means of sliding contacts. The wire 6 may be an endless wire. The velocity of the gas can be varied by changing to a different size of nozzle 26.

Title: Improvements in or relating to reduction of 3-keto steroids to 3a-hydroxy steroids
IPC: C07J7/00
Filed: 1952-12-18
Abstract: The invention comprises 5-isostigmast-22-en-3a -ol, the alkyl esters of 3a -hydroxy-D 7-bisnorcholenic acid, e.g. the methyl ester, and a process for reducing the 3-keto group of a 3-keto A/B cis steroid by reaction with lithium aluminium hydride in an anhydrous solvent medium, and hydrolysing the reaction product, e.g. with aqueous hydrochloric acid, to form a 3a -hydroxy A/B cis steroid.  The 3-keto A/B cis steroid may contain double bonds in the nucleus, hindered keto groups elsewhere in the steroid nucleus such as in the 11- or 12-position or carboxylic ester groups present in the side chain substituted at C17 as in esters of the bisnorcholanic acid series, e.g. esters of 3-ketobisnorcholanic acid, 3,11-diketo-bisnorcholanic acid and 3-keto-D 7-bisnorcholanic acid such as the methyl esters. If the 3-keto group is the sole unhindered oxo group in the steroid reactant, 1/4 mol. of lithium aluminium hydride is sufficient to carry out the reduction.  Additional unhindered reactive keto groups are preferably protected, e.g. by conversion to cyclic ketal groups by reaction with an alkylene glycol.  The process may be used to prepare pregnan-3a -ol-20-one from pregnan-3,20-dione through the intermediate 20-ethylene ketal, etiocholan-3a -ol-17-one from etiocholandione-3,17 through the intermediate 17-ethylene ketal, coproergost-22-en - 3a  - ol from coproergostenone, 5 - isostigmast - 22 - en - 3a  - ol from 5 - isostigmast-22 - en - 3 - one, methyl 3a - hydroxy - bisnorcholanate from methyl-3-keto-bisnorcholanate, methyl - 3a  - hydroxy - D 7 - bisnorcholenate from methyl - 3 - keto - D 7 - bisnorcholenate, and methyl - 3a  - hydroxy - 11 - keto - bisnorcholanate from methyl - 3,11 - diketo - bisnorcholanate.  The examples refer in detail to the preparation of the compounds referred to above, and, in addition, refer to the following compounds: 5 - isostigmast - 22 - en - 3a  - ol acetate (obtained from the corresponding 3a -hydroxy compound by reaction with acetic anhydride), 3a  - acetoxybisnorcholanic acid (obtained by hydrolysing the corresponding methyl ester with potassium hydroxide.  Esters other than the methyl ester of the bisnorcholanic acid series may be used in the above process, e.g. the propyl, isobutyl, benzyl and naphthyl esters may be used.  Esters of other side chain steroid acids are also suitable, e.g. the esters of cholanic, norcholanic and etiocholanic acids.  Specification 736,818 is referred to.
Patent GB-435656-A (GB)
Title: Improvements in or relating to malleable iron, and to grey cast iron
IPC: C22C37/00
Filed: 1934-11-17
Abstract: The physical properties of malleable and grey cast iron are improved by the addition of 0,25-3 per cent of copper, 0,05-0,5 per cent of titanium and optionally 0,015-0,15 per cent of aluminium.  High strength grey cast iron is made by using metal suited to the production of malleable cast iron, and by making additions to produce, by a treatment shorter than the usual annealing process, a grey cast iron.  The copper and aluminium are added either in their single unalloyed state or combined in the form of alloys and the titanium can be added as an alloy such as ferro-titanium.  For the production of malleable cast iron, the silicon or carbon content should be reduced to prevent the formation of primary graphite, but in the case of grey cast iron these contents should be increased, and the carbon or silicon content, or both, adjusted according to the section of the article to be cast.  Specification 390,687 is referred to.

Abstract: 844,180. Variable-speed gear. CURTISSWRIGHT CORPORATION. Oct. 21, 1957, No. 32823/57. Class 80 (2). [Also in Group XXVI] In a governing mechanism for a prime mover (see also Group XXVI) an input shaft 22 driven by the prime mover at a fixed speed ratio drives, through a plate 30 and cage 32, ball assemblies 164, 158 of continuously-variable-ratio ball planetary gears 24, 26 and balls 115 located between opposed conical races 110, 112 and actuating, due to centrifugal force, a spring- loaded member 72 whose movement is transmitted by a lever 126 and member 124 to the ratio-adjuster 148 that controls, through a leaf-spring 200, the tilt of the ball assembly 158. The output race 154 of gear 26 is integral with the input race 160 of gear 24 and the output races 154 and 162 are integral with rings 38 and 40, respectively forming input components of a ball differential 36 including a spring-loaded reaction-ring 42 and a ball-cage 44 carrying a gear 34 which moves according to the summation of the speed error outputs of the gears 24 and 26 and is connected to the prime mover throttle control-rod 18. Rotation of the race 162 causes axial movement of a non-rotatable sleeve 170 to thereby move the ratio-adjuster 166 and restore the gear ratio to normal when the speed error has been corrected. The carrier 186 of the fixed race 156 of gear 26 is rockably mounted and held in position by springs 188 and has a cam surface 190 which, by acting on a rod 192 connected to the governor speed-setting member 134, compensates for torque reaction displacement of the carrier 136.
