Filed: 1928-03-15
Abstract: 313,646. Johnson, D. H. March 15, 1928. Loud-speakers; diaphragms; magnetic instruments.-In a sound reproducing device, the cone or other driven member is supported from a plurality of points so that it can move freely in an axial direction and is equally free at the points of support to be distorted or deviated from its normal shape, when vibrating but is prevented from movement as a whole in a direction transverse to the axis. Figs. 1 and 2 show a construction of moving coil loud-speaker in which the conical diaphragm 1 has a number of cords 9 secured tangentially to its surface near its outer end so as to form a square, the corners of which are connected bv cords 11 with resilient supports 12 on a ring 6 carried by a base plate 7. A similar arrangement of cords 13 may be provided for supporting and centring the inner end of the cone 1 and coil 3, the cords being secured to adjusting screws 14 mounted in brackets 15 on the magnets 5. The cords 11 may be attached to pins on the ring 6 or they may be dispensed with, the corners of the square formed by the cords 9 being secured directly to pins on the ring 6. In the modified arrangement, Fig. 4, the cords 9 form four of the sides of an octagon, the remaining sides of which are formed by cords 17. Each angular point of the octagon is connected by cords 18 to the ring 6. Any number of cords 9 may be employed, e.g. they may form a triangle. The cords are preferably spaced a short distance away from the surface of the cone by securing them to small paper washers 10, but if they are directly connected to the cone, they are preferably arranged so as to make a slight angle, with the tangent line on both sides of the point of attachment. The cords 11 may be replaced by or provided with coil springs and the tension of the main cords adjusted either by screws 14 as shown in Fig. 1 or by attaching each suspension cord to a C spring 22, Fig. 6, secured to a slide 23 which is mounted or a bracket 24 and adjustable by a screw 25.

Title: Improvements in or relating to processes for the manufacture of anodes for use in the production of aluminium, beryllium, magnesium, or alkali earth metals by electrolysis of fused starting materials
IPC: C25C7/02
Filed: 1938-03-16
Abstract: 511,076. Anodes. GES. ZUR VERWERTUNG CHEMISCH TECHNISCHER VERFAHREN VADUZ. March 16, 1938, Nos. 8103 and 8104. Convention dates, March 16, 1937, and Jan. 17, 1938. [Class 41] Anodes for use in the production of aluminium, beryllium, magnesium or alkali earth metals by the electrolysis in the molten state of halogenous salts of the metal to be produced, which comprise an intimate mixture of carbon or carbonaceous material and an oxide of the metal to be produced, are made by intimately mixing tar or pitch or a mixture of tar and pitch with an oxide of the metal to be produced by electrolysis, subjecting the mixture of these ingredients to distillation protected from air to eliminate the volatile products, cooling and reducing to powder, and using the resulting powder as raw material for the manufacture of anodes by compressing and baking. The tar or pitch may be replaced in part by a mixture of carbon powder and tar and/or pitch, and the carbonaceous material may be added in a plurality of stages, the mixture being each time heated protected from air and finely crushed. At any stage in the manufacture of the anodes, one of the following bodies may be added as catalysts to facilitate the reaction between the oxide of the metal, the carbon, and the halogen produced at the anode during electrolysis :-iron as metal, oxide, sulphide, or carbonate, or nickel, manganese, molybdenum or compounds thereof. The anodes, after forming or moulding, may be baked in the electrolytic furnace itself during electrolysis in any manner known per se, and may be provided with a metal supporting casing constituted by one of the above catalysts, e.g. iron. The proportion of carbon in each anode should be of the order of 15 to 25 per cent. the precise proportion of carbon being dependent on the particular case treated. The connection serving for the admission of electric current may consist of rods arranged laterally relatively to the anode and penetrating within the latter. The metallic oxides used may contain small proportions of compounds such as hydroxides or carbonates which are converted to oxide during baking and electrolysis. In cases where the oxide used requires only a small proportion of carbon, the oxide can be mixed and kneaded with the pitch and/or tar in the hot state and directly shaped in the form of an anode and baked.

Title: Improvements in or relating to polypeptides having marked acth-activity
IPC: A61K38/35
Filed: 1953-03-24
Abstract: The invention relates to corticotropin-B, its acid addition salts, to a polypeptide composition containing corticotropin-B and/or an ACTH-active derivative or corticotropin-B and to their production from pituitary gland material.  The crude material may be extracted with hydrochloric acid-acetone or methanolacetic acid and the extract contacted with oxycellulose in order to adsorb the ACTH-active substances thereon.  The oxycellulose adsorbate is eluted with a dilute mineral acid solution such as O-IN hydrochloric acid.  The pH of the eluate is adjusted to 2,5 to 3 by contacting it with a strongly basic anion exchange resin in its carbonate form and after removal of the resin by filtration the filtrate is concentrated.  The concentrate is digested with pepsin and treated with trichloracetic acid to precipitate substances of high molecular weight and low ACTH activity.  After clarification the aqueous solution is extracted with a water-immiscible organic solvent and then lyophilized.  The "pepsin-digested material" so obtained is passed in aqueous solution down a column of a carboxylic cation exchange resin such as a dihydroxybenzoic acid-formaldehyde condensate or a copolymer of a polymerizable acid and a divinyl compound such as acrylic or methacrylic acid and divinyl-benzene.  It is preferred to add a mild reducing agent such as hydrogen sulphide, sodium sulphite, thioglycollic acid or cysteine to the aqueous solution, and to use a resin in which about 15 per cent is in the sodium salt form, the remainder being the free-acid.  After washing the column, the resin adsorbate is eluted with aqueous mineral acid (HCC) of pH greater than 1,8 whereby low ACTH-active substances and substances of a lower basicity than corticotropin-B are removed. It is then eluted with aqueous mineral acid of pH from 0,0 to 1,8 whereby corticotropin-B and substances of similar basicity are removed from the resin. Lyophilization of this eluate gives a polypeptide composition containing corticotropin-B and having approximately 300 times the ACTH-activity of Armour Standard La-1-A.  Corticotropin-B may be separated from this composition by means of the Craig counter-current distribution procedure using the system s-butyl alcohol-0,5 per cent aqueous trichloracetic acid.  A detailed description of the complete procedure is given.
