Title: Method of and apparatus for recovering liquid from a filter system
IPC: B01D37/00
Filed: 1947-04-22
Abstract: A process for recovering liquid, e.g. dry-cleaning solvent from a filter system having filter means and an accumulation of sludge, and for drying them out, comprises circulating air under pressure through the filter system in contact with the filter means and the sludge to carry off the liquid, separating the liquid from the air, and venting the air from the top of the filter system to prevent it from becoming air-bound.  After repeated circulation of dry-cleaning solvent between a drum 12 and a filter 46, a solvent drain valve 67 is opened, and solvent remaining in the filter casing passes to a tank, e.g. the tank 15.  Compressed air is then admitted to a pipe 72 at the top of the filter, forcing remaining solvent through a bed of sludge S, this solvent then being removed through pipe 66 or 68. Compressed air is next applied by a pipe 74 underneath an element 62 to bulge an overlying cloth 64 and break up the sludge S as shown in dotted lines.  Air is now drawn by a blower 25 over a heater 21, through a duct 23 into the drum 12, through the perforated surface of the latter, over lint filters 27 and along a pipe 34 into the filter casing.  It extracts solvent from the sludge S, passes through bags 54, along a filtrate outlet pipe 56, along a pipe 35, over a condenser 20 from which solvent runs back into the tank 15, and back again over the heater <PICT:0631828/III/1> <PICT:0631828/III/2> 21. Steam is admitted during this cycle into the jacket formed between casings 40 and 46 of the filter.  After the drying step, the casing 46 may be opened and sludge S, filter cloth 64 and filter bags on the elements 54 removed.  After these are replaced, dry-cleaning solvent is pumped from the tank 15 by a pump 78 into the filter until it is full, the air escaping through a vent 83 and passing back to the cleaning casing 10 so that solvent contained in it may be recovered. The apparatus is now ready for a series of dry-cleaning operations.

Title: Improvements in electrolytic decomposing devices
IPC: C25B9/20
Filed: 1934-04-09
Abstract: 421,310. Electrolytic cells. TENNANT, W. J., 111, Hatton Garden, London.- (Druckzersetzer Ges. ; 30, Viktoriastrasse, Berlin) April 9, 1934, No. 10700. [Class 41] A cell particularly for the production of hydrogen and oxygen at high pressure is built up of frames 3, Fig. 2, on both sides of which permeable electrodes of the same polarity are mounted to form an electrolyte chamber. The anode frame shown is provided with a groove 21 to receive each electrode, the groove being widened at 23 for the passage of the electrodeconnecting lugs. The upper walls of the chamber converge to a tapering passage 17 leading to a passage 12 formed by apertures in successive frames for the removal of the oxygenelectrolyte mixture. The bottom of the chamber is similarly connected to a passage 16 for the supply of electrolyte. The cathode frames are similarly constructed but are of greater thickness, e.g. double, and the electrode lugs emerge at the opposite side ; the enclosed chambers are connected to supply and discharge passages 14, 10. The electrodes are of perforated metal or gauze. The hydrogen electrodes are of iron and the oxygen electrodes of nickel or nickelled iron. On one of each pair of electrodes there are welded inwardly projecting spacing ribs 27 of depth slightly greater than the thick. ness of the frames so as to maintain a slight arching of the electrodes. The ribs in successive units are displaced relatively to one another. In the case of very thin electrodes, independent current supply means such as sheets may be arranged between them and these may be connected to the spacing ribs. As shown in Fig. 1, a number of anode frames 3 and cathode frames 1 are arranged with intermediate diaphragms 7 to form a group in which all the electrodes of the same polarity are connected in parallel. A number of such groups are packed in the same axis with insulating closure plates 8 and connected in series. The anode frames 5 adjoining the closure plates are thinner than the frames 3 ; each frame 5 is provided with an electrode 6 in addition to the perforated electrode which bears against the diaphragm. At the junction with the closure plates 8, the group passages 10, 12, 14, 16, Fig. 2, are connected with main passages 9, 11, 13, 15 respectively. Sheet metal insertions having no electric connections may be embedded in the closure plates 8 to prevent passage of shunt currents by absorbed electrolyte. The diaphragms 7 may be of the external dimensions of the frames, being suitably impregnated at the edges and provided with corresponding passages, or they may be smaller and embedded in the frames. The complete electrolyzer is secured between press plates by external bolts provided with insulating rollers. Corresponding electrode lugs are connected by copper bars 38. The electrolyzer is mounted in a half-open iron casing 46 provided with supporting members 47 on which rest insulating members 49 secured to the bars 38.

Title: Process for the production of threads, fibres, bristles and films from polyethylene terephthalate by the melt spinning process
IPC: D01F6/62
Filed: 1953-04-20
Abstract: In the melt-spinning of polyethylene terephthalate threads, fibres, bristles and films, polyethylene terephthalate which has been condensed in solution in a high boiling point solvent, e.g. diphenyl methane, diphenyl oxide, diphenyl or benzophenone, and which still contains 10-30 per cent by weight of the solvent, is melted by heating at 240-270 DEG  C., and the melt is spun through an extrusion nozzle maintained at a temperature above the boiling point of the solvent, preferably 260-320 DEG  C.  The presence of the solvent reduces the melting point of the melt, prevents its decomposition at the nozzle and lowers its viscosity, thereby facilitating its passage through the melting grate as described, for example, in Specification 533,307 and through the pump passages.  Any residual solvent in the filaments enables them to be strongly stretched at lower temperatures.  After stretching, traces of the solvent may be removed from the filaments by washing under pressure with hot low boiling point solvents such as carbon tetrachloride, acetone or methanol.

Title: Improvements in the manufacture and production of orange vat dyestuffs of the anthraquinone series
IPC: C09B1/42
Filed: 1927-04-25
Abstract: 280,492. I. G. Farbenindustrie Akt.- Ges. Nov. 15, 1926, [Convention date]. Anthraquinone dyestuffs.-Orange vat dyestuffs of the anthraquinone series are produced by introducing radicles of polyvalent alcohols into the hydroxy group of 1-acylamino-4-oxyanthraquinone this being effected by treating the latter with esters such as the halogen hydride or arylsulphonic acid esters of polyvalent alcohols in the presence of substances capable of combining with acids. The acid radicles of the esters may be partially or completely replaced by the 1-acylamino- 4. oxy anthraquinone radicles. Unexchanged acid radicles may, by a secondary reaction, be replaced by hydroxy groups. According to an example, 1-benzoylamino-4-oxyanthraquinone is boiled with p-toluene sulphonic acid #-chlorethyl ester in the presence of calcined soda and trichlorbenzene. The resulting dyestuff can be separated by crystallization from nitrobenzene into two products. The more readily soluble product probably consists of a mixture of The less readily soluble product appears to be the di-1-benzoylaminoanthraquinone derivative of ethyleneglycol. In other examples 1-benzoylamino-4-oxyanthraquinone is treated with di-ptoluenesulphonic ester of ethyleneglycol and with glyceroltri-p-toluenesulphonic ester. According to a further example, 1-m-methoxybenzoylamino-4. oxyanthraquinone which is obtained by treatment of 1-amino-4-oxyanthraquinone with m-methoxybenzoylchloride is treated with di-p-toluenesulphonic ester of ethyleneglycol.
