Title: Improvements in or relating to artificial dentures
IPC: A61C13/225
Filed: 1931-05-15
Abstract: 378,939. Dentures. SEALTI™L, D., 10, Waterlooplein, Amsterdam. May 15, 1931, No. 14360. Convention date, March 11. [Class 81 (ii).] An elastic band 5 is applied under tension to the part 2 of a denture which lies between the gums and the cheeks and lips, so as to fit closely against the external side of the gums and thus secure the denture in place. The elastic rubber band is applied to a vulcanite denture after vulcanization but whilst it is still warm and soft. Vulcanite or metal extensionpieces may be formed on the denture to grip the jaws, and the ends of the tensioned band may be secured thereto. The band may be extended to form a partial, or complete lining for the denture. The Specification as open to inspection under Sect. 91 (3) (a) describes and shows on the drawings a construction wherein a metal plate having a serrated edge is positioned between the vulcanite denture and the soft rubber lining thereof and said plate carries the stretched elastic band which is threaded between the .serrations. Extension pieces are formed at the ends of the metal plate and may be slit to hold the elastic band, or may have their edges bent over the elastic band to hold the same under tension. The soft rubber lining may extend over the whole surface of the metal plate or may be applied as separate cushions or pads. This subject-matter does not appear in the Specification as accepted.

Title: A method of producing ammonium salts
IPC: C01C1/24
Filed: 1928-05-16
Abstract: 310,673. Tern, R. May 16, 1928. Ammonium chloride and salts thereof in general; sodium sulphate.-In a dry process for obtaining readily-volatile ammonium salts by reacting an ammonium salt with a salt of an acid the ammonium salt of which is required, the mixed reacting salts are reduced, as in a mill, to a colloidal state, and the colloidal mixture then heated in an inclined revolving vessel, the ammonium salt being electrically precipitated from the evolved vapours and the other product of the reaction being obtained in solid form at the lower end of the revolving vessel. Air may be passed through the latter during the heating step. An example relates to the production of ammonium chloride and sodium sulphate from ammonium sulphate and sodium chloride, the colloidalized mixture being heated at 300‹ C.

Title: Improvements in and relating to the manufacture of deep drawing sheet, iron or steel
IPC: C21D8/04
Filed: 1945-06-07
Abstract: In a process of producing a deep drawing iron or mild steel sheet or strip in which the stock is hot rolled, then cold rolled and subsequently stabilised by heat treatment, the hot rolled stock at a temperature not lower than 1525 DEG  F. is rapidly cooled to between 1100 DEG  F. and 1375 DEG  F. and then slowly cooled to the cold rolling temperature.  In an example, a steel containing up to .08 per cent carbon, .15 to .40 per cent manganese with low copper and sulphur content is deoxidised with aluminium which is added in an amount such as to leave a residue of .02 to .08 per cent.  Ingots of this steel are hot rolled to about .10 inches, finishing the rolling operation in the range of 1525 DEG  F. to 1650 DEG  F. or higher. The material is then cooled in air, or more rapidly to between 1100 DEG  F. and 1375 DEG  F. after which the cooling to atmospheric temperature is retarded by coiling or stacking according to whether the material is in strip or sheet form.  The material is then reduced from 30-70 per cent by cold rolling and is annealed at 1250 DEG  F. to 1400 DEG  F. for four or more hours and then cooled to room temperature at a slow rate preferably about 25 DEG  per hour.  Sheets made in this manner have a flattened or spheroidal grain characteristic, are non-aging and have good deep drawing characteristics.  U.S.A. Specification 2,069,758 is referred to.

Abstract: 1383085 Microspherical carbon particles; active carbon KUREHA KAGAKU KOGYO KK 28 March 1972 [27 Aug 1971] 14559/72 Heading C1A [Also in Division C5] Microspherical carbon particles of a diameter of from 10 to 5000 microns are produced by fusing a pitch having a softening point of 50‹ to 350‹ C.; a carbon content of 80 to 97% by weight and a hydrogen/carbon atomic ratio of 0À2 o 2À5 and a nitrobenzene insoluble fraction of 0 to 50% by weight, dispersing the fused pitch in an aqueous medium which contains a dispersing aid and has a temp. of 50-300‹ C.; cooling the dispersion to produce solid microspherical particles; separating and subjecting these particles to an infusibilization treatment in an oxidizing environment to raise their softening point and carbonizing these particles whilst still maintaining their particulate form. A solvent may be mixed with the pitch prior to dispersion, and this solvent is removed before the particles are treated to raise their softening point. The dispersing or suspending aid may be a water-soluble organic polymeric material e.g. partially saponified polyvinyl acetate, polyvinyl alcohol, methyl cellulose, polyacrylic acid, or salt thereof, polyethylene glycol or an ether or ester derivative thereof, starch, gelatin or mixtures thereof. The dispersing or suspension aid may be present in a concentration of from 0À05 to 5% by weight. The solvent for the pitch may be an aliphatic hydrocarbon, an aromatic hydrocarbon, or an alicyclic hydrocarbon. The softening point of the particles may be raised by contacting with an oxidizing liquid, e.g. H 2 SO 4 , H 3 PO 4 , HNO 3 , aqueous chromic acid or aqueous KMnO 4 . Alternatively, the oxidizing step may be performed in a gaseous oxidizing atmosphere, e.g. comprising MO 21 O 2 , O 3 , SO 2 , Cl 2 , Br 2  or mixtures thereof, or mixtures thereof with air M 2 , Ar, or other inert diluent gas. After carbonizing, the particles may be activated by contacting with steam at 800- 1200‹ C. The carbonization and activation may be performed sequentially in the same apparatus. The carbonization may be performed at a temp. sufficient to graphitize the particles, e.g. a temp. of 2800‹ to 3000‹ C.

Title: Improvements in and relating to the manufacture of thermosetting resins and mouldingcompositions
IPC: C08G16/02
Filed: 1948-05-31
Abstract: Thermosetting resins and moulding compositions are obtained by treating the resin of Wallaba wood (Eperua Falcata), previously extracted or still in the wood with an aldehyde, or with a condensation product prepared from excess aldehyde and a substance which reacts with the aldehyde to produce a thermosetting resin, e.g. urea or phenol.  Aldehydes mentioned are formaldehyde and paraformaldehyde.  The latter mixed with disintegrated Wallaba wood and other desired ingredients forms a moulding composition. To assist uniform reaction with the aldehyde a solvent for the resin, e.g. ethylene glycol, acetone, diacetone alcohol, white spirit or "Cellosolve" (Registered Trade Mark), may be present during the reaction.  A catalyst may be added.  In examples: (1) ground Wallaba wood is intimately mixed with paraformaldehyde and, if desired, hexamethylenetetramine; (2) as in (1) with addition of ethylene glycol; (3) ground Wallaba wood is heated under reflux with acetone, formaldehyde solution and oxalic acid.  Acetone and water are removed by distillation and the ground residue mixed with hexamethylenetetramine, stearic acid and magnesium oxide; (4) Wallaba wood is used which has been fortified by admixture with resins extracted from other Wallaba wood; (5) Wallaba wood is milled on hot rollers with a urea-formaldehyde condensation product containing excess aldehyde; (6) is similar to (5) but employs a phenol-formaldehyde condensation product; (7) Wallaba resin is reacted with furfuraldehyde in presence of "Cellosolve" and triethanolamine.  The products may be formed into boards or sheets.
