Title: Improvements in or relating to the manufacture of inorganic hydrous oxide gels, suchas silica gels, in microspheroidal form
IPC: B01J21/12
Filed: 1947-07-04
Abstract: <PICT:0644322/III/1> Microspheroidal inorganic hydrous oxide gels are made by preparing an aqueous slurry consisting of 3-6 per cent of the hydrous oxide gel in water containing soluble alkali metal salts, filtering the slurry and washing the filter cake, reforming a slurry of the filter cake in water to give a content of 3.5-8.8 per cent by weight of the gel, spraying the slurry into a current of hot gases at a temperature of at least 600 DEG  F., and preferably up to 1200 DEG F., and maintaining the particles suspended in the gas stream while the free water of the slurry is evaporated.  The slurries, preferably made by the process outlined in Fig. 1 (not shown), and disclosed in Specification 626,455, are passed into a shell 42 and pumped on to a revolving vaned wheel 44 from which small particles of gel are thrown into a cylinder and descend in a helical path caused by the swirling motion of hot gases introduced through ducts 36, 38, manifold 37, cone 39 and vanes 40.  The gases containing the dried gel pass out of a conical bottom 32, having a lower detachable portion, into cyclone separators.  Gels specified are those containing an oxide of Si, Fe, Al, V, Cu, Ni, Ti, Th, Mn, Cr, Zr or Mg or any two or more of these oxides.  They may be used as catalysts, particularly in fluidized form, in cracking, dehydrating, hydrogenating, dehydrogenating or reduction processes or for synthesizing hydrocarbons or alcohols or they may be used as absorbents, e.g. for dehumidifying.

Title: Process for improving the resistance of glass surfaces to the action of liquids, more especially water, and moisture contained in air or gas
IPC: C03C17/245
Filed: 1959-05-26
Abstract: 852,270. Treatment of glass surfaces. DEUTSCHE TAFELGLAS AKTIENGESELLSCHAFT DETAG. May 26, 1959 [June 21, 1958], No. 17966/59. Class 56. In a process for improving the resistance of glass surfaces to the action of liquids, more especially water and moisture contained in air or gas, in which the hot glass surface is treated with halides of metals such as aluminium zirconium or zinc which have an amphoteric action or form weakly basic oxides, a hot gas stream is directed towards the glass surface, the stream having added or included therein in addition to the said halides, substances which are able to form halides from the amphoteric oxides of the metals and consist more especially of halides of sulphur and/or carbon. Aluminium chloride and carbon tetrachloride are preferred or the bromides may be substituted. As shown in Fig. 3, a glass sheet 11 drawn upwards by rollers 13, 14, 15 is treated while still hot in the upper part 12 of the drawing apparatus by vaporising boxes 17 on each side. Carbon tetrachoride is introduced through supply pipes 21 and is vaporised by the heat of the glass 11 to form a concentrated stream 20 which passes through a porous plate 18 which consists of alumina, to form aluminium chloride, the two chlorides reacting on the sheet 11. A second porous plate 19 may be arranged inwardly of the plate 18, the plates either being of the same material or the plate 19 of a material reacting relatively easily with the carbon tetrachloride and that of the plate 18 less easily. In a further arrangement, not shown, the vaporiser box has secured above, more or less centrally, a container from which the carbon tetrachloride drips continually followed by a container for anhydrous aluminium chloride with a porous section fitting across the vaporiser box, and a hot air stream being passed through the box becomes saturated with carbon tetrachloride and picks up small quantities of and volatizes the aluminium chloride before reaching the glass sheet 11. As shown in Fig. 5, for treating the insides of hollow glass containers 29 intermittently brought on a conveyor 30 to a position under a vaporiser unit 25, the unit 25 can be supplied with carbon tetrachloride from a pipe 27 and has a depending porous hollow element 26 consisting of a metal oxide which can be lowered to the position shown inside the hollow container 29 when the stream of carbon tetrachloride is started. After the surface has been treated, the stream of carbon tetrachloride is stopped and the element 26 is then raised to lie between the two parts of an electric furnace 28 which are moved to enclose the element 26 while the next container 29 is moved into position.

Title: Fire alarm devices and in installations including such devices
IPC: G08B25/00
Filed: 1975-04-30
Abstract: 1478952 Ionization smoke detectors CERBERUS AG 30 April 1975 [14 June 1974 (2)] 18070/75 Heading G1N [Also in Division G4] In a fire alarm including a sensor 2 responsive to combustion phenomena and a circuit for providing a signal when the sensor output circuit exceeds a predetermined threshold, the circuit includes at least one voltage-responsive circuit, such as Zener diode 55, the resistance of which is changed by a voltage supplied by a line 5, 6 and is arranged to alter stepwise the resistance of a transistor 53 or other component so as to change the threshold level of the circuit. As described, the sensor 2 may be a smoke-detecting ionization chamber used in conjunction with a reference chamber 1 and coupled to a FET8 so that, normally in the event of a fire Zener diode 41 breaks down, turning on transistor 44 which turns on the electronic switch comprising transistors 11, 12 so as to increase the current supplied by line 5, 6 from a central station. If the voltage fed to line 5, 6 is increased, Zener diode 55 breaks down turning on transistor 53, bringing into operation a transistor 51 and a Zener diode 45 so as to reduce the threshold of the circuit. A further increase in voltage at 5, 6 turns on Zener diode 56 which brings in transistors 54, 52 and Zener diode 46 which reduces the threshold still further. The invention may be used to test the system by reducing the threshold sufficiently that alarm conditions are simulated. Modifications In Fig. 3 (not shown), the pair of ionization chambers (1, 2) are replaced by a photo-voltaic diode. In Fig. 5 (not shown), the alarm signal is fed from the source of FET8 along a separate line to a central station. In Fig. 6 (not shown), a relay is included in series with line 5 at the central station so as to indicate the increased current in alarm conditions.

Title: Improvements in and relating to the production of thread from viscose
IPC: D01F2/10
Filed: 1940-12-24
Abstract: 546,051. Artificial silk &c. COURTAULDS, Ltd., ROSE, L., and WHARTON, J. Dec. 24, 1940, No. 18094. [Class 2 (ii)] Artificial filaments are obtained by extruding, into a coagulating bath, preferably one containing sulphuric acid and at least one metallic sulphate, viscose containing a small proportion of a cation-active compound and also an anionactive compound in amount greater than the equivalent of the cation-active compound present. The presence of these compounds in the viscose reduces the tendency for the spinning jets to become clogged by precipitation of cellulose on the walls of the orifices. A solution containing the cation-active compound and excess of the anion-active compound may be obtained by taking an alkaline solution of anion-active compound and adding to it a quantity of cation-active compound such that a solution with no precipitate is obtained. The anion-active compound may be added to the viscose as such or a non-ionogenic compound which will hydrolyse in the presence of alkali to give an anion-active compound may be used. The cation-active compound may be octadecyl pyridinium bromide, lauryl pyridinium sulphate, dodecyl pyridinium sulphate, or oleyl amido ethyl diethylamine hydrochloride. The anionactive compound may be Turkey red oil or other sulphonated oil, a long-chain alkyl sodium sulphate, a pulp resin soap, an alkyl naphthalene sodium sulphonate, or sodium oleate or like soap. Polyglycol laurate, and polyglycerol stearate are examples of non- ionogenic compounds which hydrolyse in alkaline solution to form surface-active anions. The proportion of cation-active substance may be as low as 0.001 per cent. of the weight of the viscose. In an example, an aqueous solution of octadecyl pyridinium bromide is added to an aqueous solution of Turkey red oil. Caustic soda solution is added. A small amount of the clear solution is added to viscose and the mixture is extruded into a coagulating bath containing sulphuric acid, sodium sulphate, zinc sulphate, and glucose. Specifications 181,901, 336,250, [both in Class 2 (ii)], 340,564, 363,441, 440,647, 469,817, and 478,774 are referred to.
