Title: Improvements relating to the treatment of asbestos fibre
IPC: D02G3/20
Filed: 1943-01-21
Abstract: Cleaned fibres having substantially the potential textile qualities of the starting fibres are produced from milled asbestos fibre by scrubbing or washing masses of the fibre with water to remove entrained dust without twisting the fibres into rope-like strands compacting the masses into sheets, drying and fiberizing the sheets and liberating the fibres from the sheets by the action of compressed air without substantially reducing the staple length.  The masses of milled asbestos fibre are washed at A, Fig. 1, by immersion in a pool of water into which air is injected to cause circulation, <PICT:0583846/IV/1> <PICT:0583846/IV/2> partially drained at B, compacted and further drained at C, and then dried, partially disentangled, fiberized, threshed or opened, fluffed or teased, and finally collected.  In operation, the tank A is filled with water to a desired depth and the vertically adjustable discharge pipe 30 set correspondingly. Masses of asbestos are then allowed to soak therein to soften the adhering dust and the water is agitated in a circular motion by compressed air issuing from jets in a supply pipe 20. Sufficient water is fed through jets in a circular supply pipe to cause a slight overflow so that dirt is washed away through the pipe 30. Water may also be supplied through a pipe which causes a circular movement of the asbestos about the tank.  When the water becomes clear, the circulation is stopped, the pipe 30 lowered and the asbestos allowed to pass down the shoot 49 to the vibrating screen 50 through which water flows into the hopper 52, the asbestos passing into the tank 62.  The fibres are sucked on to the surface of the filter cylinder 70, the sections of which are separately exhausted through a valve system 82, the asbestos then being stripped by parallel bands 87 as the cylinder rotates. Alternatively, the filter may comprise a cylindrical perforated plate 170, Fig. 1A, coacting with rollers 145-148, the rollers 145, 146 rotating clockwise and the rollers 147, 148 anti-clockwise to drive the plate 170, the fibres being fed through spouts 53, 160 and detached from the top of the cylinder 170 by compressed air nozzles 55 on to a plate 56.

Abstract: 555,062. Dashpots. POTTER, C. A. Jan. 28, 1942, No. 1185. [Class 108 (iii)] [Also in Groups XI, XXIX and XXXVII] An incinerator for sanitary towels and like absorbent material comprises an incinerating chamber provided with a closure device displaceable for insertion of the towel or like material into the chamber, heating means for destroying the material controlled by movement of the closure device and means for creating an air draught through inlets at the bottom of the chamber. The heating means may consist of a gas burner or electrically heated elements. Figs. 1 and 2 show an incinerating chamber A with a gas burner B and grate 12 on which the material is deposited after lifting the fireclay-lined lid 15 about its hinge pin 17. The action of lifting the lid opens the gas supply valve 46 through arms 20, slotted link 50 and lever 47 the gas being ignited by a pilot burner 43. Air is admitted to the ashpit through radial pipes 35. After closing the lid the gas supply valve is gradually closed by the action of a timing device, Figs. 1 and 4, consisting of a cylinder 53 with a piston 54 which is raised by one arm of the lever 47 when the lid is lifted and is lowered by the action of a spring 57, the rate of lowering being controlled by a needle valve 60 which controls the escape of air from the underside of the piston and thus the rate of closing of the gas supply valve. The incinerator shown in Fig. 5 comprises a pivoted hearth 72 at the base of the chamber A<SP>1</SP> containing electric heating elements covered with mica or like refractory material for supporting the material to be incinerated. When the pivoted door 79 is opened to insert material to be burnt, the hearth is tilted by levers 86, 88 connected by a link 87 to deposit any ashes &c. remaining on the hearth from a previous incineration, into the ashpit C<SP>1</SP>. As the lever 88 moves upwardly a pin 111 thereon engages a fork 109 on the piston rod of the timing device D<SP>1</SP> which is similar to that described above. The fork 109 in its upward movement releases a spring-pressed switch lever 105 to close contacts 106, 107 and allow current to pass from the mains to the heating elements B<SP>1</SP> and to a motor driving fan F which draws air through louvres 96, 97 and exhausts ashes &c. from the pit C<SP>1</SP>. Instead of electric heating elements, a burner similar to that'shown in Fig. 2 may be embodied in the hearth 72 and covered by a plain or apertured plate of non-oxidizing metal, the gas supply to the burner being passed through the hollow spindle of the hearth and controlled by a gas supply valve and timing device as described above. Specifications 248,112, [Class 126], and 474,527, [Group XXIX], are referred to.

Abstract: The invention comprises 11a - and 11b -acylamino - D 4 - pregnene - 17a , 21 - diol - 3, 20 - diones and the corresponding D 1,4-pregnadienes and 11a -amino-steroids of the pregnane and allopregnane series of the general formula <FORM:0887815/IV (b)/1> wherein X represents hydrogen or an a -hydroxy group, Y represents hydrogen or a hydroxyl or alkanoyloxy group, Z represents a hydroxy, keto or ketal group and R represents hydrogen or an alkanoyl group (the alkanoyloxy and alkanoyl groups are saturated aliphatic groups having not more than 4 carbon atoms) and the corresponding N-acylated compounds, and a process for the preparation of 11a  and 11b -amino-steroids of the pregnane and allopregnane series of the above general formula wherein X, Y, Z and R have the above significance, by reducing the corresponding 11-oximino compounds by any method known for the direct reduction of an oxime to the corresponding amine, and, if necessary, removing the 20-ketal group to form a 20-keto group. The above process may be extended in that the 11-amino group may be acylated to form the corresponding 11-acylamino compounds.  When the above reduction process is carried out with sodium in alcohol or sodium amalgam in an aqueous medium on 11a -amino-steroids is formed and when the reduction is carried out with lithium aluminium hydride or by catalytic hydrogenation in an acid medium an 11b -amino-steroid is formed.  The 11a -amino-pregnane-3a ,17a ,20b -triol may be acylated to form an N-aryl-3,20-diacyloxy compound the ester groups of which may be hydrolysed by treatment with refluxing aqueous methanolic sodium hydroxide for a short period to form an 11a -acylaminopregnane-3a ,17a ,20b -triol.  The latter compound or the corresponding 11b -acylamino compound may be converted to 11a -acylaminopregnane-17a -ol-3,20-dione or the corresponding 11b -acylamino-compound by oxidising with chromium trioxide in pyridine with N-bromo-acetamide or with N-bromo-succinimide. Further treatment by selectively reducing the 3-keto group to form an 11a  (or b )-acylamino-pregnane-3a ,17a -diol-20-one, e.g. with sodium borohydride or hydrogen in the presence of Raney nickel, brominating to form the corresponding 21-bromo compound, reacting with potassium acetate to form 11a  (or b )-acylamino - 21 - acetoxy - pregnane - 3a , 17a  - 3,20-dione, brominating at C4 to form the corresponding 4-bromo-compound, dehydrobrominating to form 11a  (or b )-acylamino-21-acetoxy-D 4-pregnene-17a -ol-3,20-dione, and hydrolysing with acid or alkali forms 11a -acylamino-D 4-pregnene-17a ,21-diol-3,20-dione, and optionally dehydrogenating with selenium dioxide or dehydrogenating by means of a biochemical method forms 11a (or b )-acylamino-D 1,4-pregnadiene-17a ,21-diol-3,20-dione.
