Title: Process for obtaining tricalcium saccharate rich in sugar and poor in lime and of a very high degree of purity
IPC: C13B35/04
Filed: 1925-08-01
Abstract: 252,110. Steffen, C. J., (known as Steffen, C.). May 18, 1925, [Convention date]. Purifying saccharine liquids; refining sugar.-Tri-calcium saccharate rich in sugar and poor in lime and of high purity is obtained by mashing tricalcium saccharate, obtained from a molasses solution, into a cold low percentage sugar solution, one and a half to three-fold the quantity of sugar in the sugar solution being added in the form of saccharate. fine lime powder being next added to precipitate the calcium saccharate dissolved in the mixture, and the saccharate then separated, for example by filter-pressing. In the process described, lye from a container L2 and molasses from a container W are drawn through pipes a, b, into a precipitating vessel Fl, the mixture having a sugar content of about 6-6.5 per cent. The mixture is treated to precipitate tricalcium saccharate therefrom by circulating it by means of a pump T1, through pipe c, cooler K1. and container S1, where finely powdered lime from supply M1 is continuously strewn on the flowing liquid, and back to the precipitation vessel F1. The cycle is repeated until the required amount of saccharate is precipitated. The liquid is next fed by pump P1 through pipes c1, c2, to the filter press A1 where saccharate, is separated, the lye obtained being led away through pipe d, if desired to an evaporator. The saccharate is mashed in a masher B1 with cold diluted syrups, or molasses of 1-2 per cent sugar content, or with lime water. The mashed saccharate is fed by pump P4 through pipes e1, e2, to a container R provided with stirring apparatus. The second precipitation vessel F2 contains a 1¢-2 per cent sugar solution formed from juices, syrups, waste liquids, molasses, &c., the solution being circulated by pump T2 through cooler K2 and container S2, where the mashed saccharate is added through pipe g from container R, and back to vessel F2. The circulation is continued until the required amount of saccharate is added. Finely divided lime from supply M2 is next added to the circulating liquid until approximately only about 0.5 per cent of sugar is left in solution. The liquid is then fed by pump P2 to filter-press A2, where the saccharate is separated and fed to masher B2 from which it is removed through pipe s. The lye obtained in the filter-press A2 passes through pipe m to container L1, from which it is fed by pump P3 through pipe n to container L2 for use as dilution liquid in the first precipitation. The process may be combined with a known tricalcium saccharate precipitating and purifying process by employing part, e,g. 25 per cent. of the finished saccharate suspension as washing liquid for saccharate obtained from an impure sugar solution of 5-7 per cent concentration and filter-pressed, the washing taking place in the press.

Title: Process for glueing leather, and adhesive materials therefor
IPC: C09J5/00
Filed: 1929-06-27
Abstract: 314,867. Stelkens, W. July 3, 1928, [Convention date]. Adhesives.-In a process for the glueing of leather, the adhesive is used in the form of a dry powder or film between the surfaces to be glued. The softening of the dry material and resulting adhesion of the surfaces is carried out by warming, or by moistening the surfaces to be glued or the adhesive film itself with a suitable solvent, to such an extent that no actual solution, but only a swelling of the adhesive occurs. The glueing may then be completed by pressure. Suitable adhesives are water-resisting, such as cellulose esters or ethers, indiarubber together with known non-volatile plastifiers, resinous condensation or polymerization products of organic compounds, espevcially mixtures with cellulose esters. According to examples (1) acetyl cellulose, and triphenyl phosphate are mixed in a dry powdered state. The leather surfaces are moistened by brushing with a solution of acetyl cellulose in acetone, and the dry powder is spread uniformly over the moistened surface and excess removed by tapping. Thetreated surfaces are pressed together while warming, and complete adhesion is soon obtained. (2) Nitro-cellulose, tri-phenyl phosphate and dibutyl phthalate are dissolved in a mixture of alcohol and ether in such proportions that a film is obtained when the solution is poured over a smooth surface. To facilitate the removal of such a film, gauze is laid on the surface on which it is poured, and becomes embedded in the film on drying. For glueing, the surfaces are moistened with alcohol, the film laid between and the whole placed under pressure for a short time.

Title: Improved process, apparatus and machine for removing stains from fabrics
IPC: D06L1/20
Filed: 1934-07-12
Abstract: <PICT:0427071/IV/1> Stains, particularly those produced during manufacture, are removed from fabrics by covering them with a cleansing material, such as soap or sulphonated castor oil, causing this to penetrate into the fabric, passing a washing and rinsing liquid under pressure through the stretched fabric, removing this liquid and partially drying the fabric by passing a gas therethrough and finally drying between rollers.  Apparatus for carrying out the process comprises a table 9 with gap 9<1> across which the fabric is drawn for inspection, by rollers 15 driven by a belt 28. Upon a stain appearing, a clutch is thrown out to stop the rolls 15, soap &c. is applied, and the machine restarted to draw the stain under a fixed head 4.  This clutch is again thrown out, and another clutch engaged to cause a cam shaft 32 to rotate.  On this shaft, a cam 33 operates a rod 41 to raise a funnel 1 against the head 4 and grip the fabric between the engaging edges, a cam 38 turns on water which enters the head at 5, passes through the fabric, and is led away by the conduit 2, and a cam 34 which operates a supply of air or the like when the water is turned off, which enters the head 4 at 6.  The cam 33 then lowers the funnel 1, and the travel of the fabric is continued, drying being completed by the rolls 15.
