Title: Method for conditioning internal pressure in multiple panel units
IPC: C03C27/12
Filed: 1972-06-15
Abstract: 1359101 Multiple glazing units GLAVERBEL 15 June 1972 [18 June 1971] 28139/72 Heading C1M The gaseous pressure in the internal space formed by the sheets of a multiple glazing unit is equalized with an external gas pressure by the steps of applying a flexing force to at least one panel, establishing communication between the internal space and an external gaseous medium before or during the exertion of the force and terminating such communication prior to relieving the flexing force. Preferably equal and opposite forces are simultaneously applied to the exposed sheets of the unit. An inwardly directed flexing force may be applied by metal clamping members 9 having rubber pads 8 (Fig. 2). An outwardly directed force may be applied by using a pair of suckers 18 each communicating with a source of vacuum 20 (Fig. 4). The force may also be applied by using elastically deformable inflatable members 56 (Fig. 9) or a device 27 having two opposite screw threads 29, each thread engaging the components of a toggle link 35 which include members for exerting a flexing force on the external faces of two juxtaposed glazing units (Fig. 7). The force may further be applied when the unit is being carried on a conveyer 62 by a cam member 63 (Fig. 10). The communication between the interior of each unit and the external environment is achieved by piercing the seal joining the sheets of the unit.

Title: Improved process for the manufacture and production of artificial silk from cellulose esters or ethers
IPC: D01F2/30
Filed: 1928-10-04
Abstract: 327,420. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 4, 1928. Right of Patent relinquished. Cellulose esters and ethers, processes for making filaments from.-In the manufacture of artificial silk by spinning a solution of a cellulose ester or ether in a volatile organic solvent, the threads leaving the nozzles are treated for a short time with a volatile organic swelling agent in the liquid or vapour state, with the result that the solvent in the threads is partially replaced by the swelling agent, and soft jelly-like threads are obtained, which threads are stretched during the treatment and finally solidified by evaporation of the volatile constituents, with or without continued stretching; strong, highly orientated threads are so obtained. Similar results can be obtained by using a solution of a cellulose ester or ether in a mixture of a volatile organic solvent and a volatile organic swelling agent, or in a solvent mixture of such swelling agents, a part of the solvent, or one of the swelling agents, being displaced from the threads, and the threads being further treated, as described above. Suitable swelling agents are methyl, ethyl, or propyl alcohol, and methyl ethyl ketone. According to the examples (1) a solution of cellulose acetate in acetone is spun into a bath of ethyl alcohol, or into a current of air saturated with the vapour of ethyl alcohol, and the jelly-like threads so produced are drawn off at a speed higher than that at which they are extruded, and finally passed through a current of warm air; (2) a solution of ethyl cellulose in a mixture of equal parts of alcohol and benzene, and (3) a solution of nitrocellulose in a mixture of equal parts of alcohol and ether, are spun as in example (1). Specification 325,857 is referred to.

Title: Process for the production of high grade iron oxide from iron sulphate
Inventor: HENNEBERGER FRIEDRICH
IPC: C01G49/06
Filed: 1961-08-08
Abstract: High grade iron oxides are obtained from ferrous sulphate heptahydrate by drying to the monohydrate, granulating to a grain size of 0.3-3 mm., decomposing at 800-900 DEG  C. under constant agitation for a period which ensures that 80-95% of the monohydrated is converted to the oxide, and then washing out the soluble parts with water.  Variation in the degree of decomposition gives rise to products having different suitabilities e.g. 80-85% decomposition yields products suitable for conversion into magnetic recording media, whilst 95% decomposition yields an alpha-Fe2O3 suitable for ferrites.  In examples ferrous sulphate heptahydrate in the wet filter cake or recrystallized form is dried in a rotating tube with air heated to 80-200 DEG  C. Aggregates of over 3 mm. in the monohydrate are crushed before decomposition in an electrically heated rotary tube. Final washing may be carried out while heating to 60 DEG C. with stirring, when the manganese content is reduced from 0.27% to 0.05%.
