Title: Process for manufacturing fibrous webs from suspensions of fibres
IPC: D21H13/40
Filed: 1972-03-03
Abstract: 1376676 Manufacturing fibrous webs; treating fibres W H W SCHULLER 3 March 1972 [5 March 1971] 10130/72 Headings D1F and D2A A fibrous web is formed by depositing an aqueous suspension of glass fibres on an endless permeable belt, the fibres being fed to a suspension mixing tank 11 in the form of units 9 of parallel, adhering fibres and which are made by winding extruded glass fibres 1 onto a rotating drum 3 sprayed at 4 with a liquid, until a layer of predetermined thickness is formed then cutting the layer to provide packets 7 of parallel, adhering fibres which are cut by a chopper 8 into the units 9 for delivery to the tank 11 by a conveyor 10. The liquid which is sprayed at 4 is preferably water or is soluble in water but may be liquids normally used as finishes or lubricants, and it acts to ensure cohesion of the fibres to each other and moistens the fibres to facilitate the cutting without substantial fibre separation or dust. The suspension is pumped from the tank 11 to another tank 16 and from there to a tank 18 supplying the endless permeable belt. A device 14 breaks up fibre bundles to ensure good dispersion. The water drained through the permeable belt is filtered and passes to a container 21 from which it is recirculated to the tank 11. The suspension may be continuously circulated from the tank 11 through the tanks 16 and 18 back to the tank 11 to ensure good fibre dispersion. Further tanks 11 and 16 may be provided. A wetting agent may be added to the suspension, e.g. by incorporating it in the liquid sprayed on the drum.

Title: Improvements in or relating to the production of phosphates
IPC: C01B25/39
Filed: 1940-06-12
Abstract: 543,911. Phosphates. MONSANTO CHEMICAL CO. June 12, 1940, No. 10271. Convention date, July 1, 1939. [Class 1 (iii)] [Also in Group XII] In a process for producing phosphates by the combustion of phosphorus with air in the presence of a salt having a replaceable anion such as sodium chloride, the liquid phosphate produced is maintained in the reaction zone in the form of fine droplets. The process is preferably carried out in a rotary furnace rotated at such a speed that the molten phosphates produced are carried round to the top of the furnace and drop in the form of rain or small droplets through the gases and vapours in the centre of the furnace. A cooling medium is applied to the exterior of the furnace to cause the formation of a shell of solid phosphate on the interior surface thereof. By supplying phosphorus, oxygen and alkali metal salt in various stoichiometric proportions it is possible to produce phosphates of various compositions such as Na 4 P 2 O 7 , Na 6 P 6 O 18 , Na 5 P 3 O 10 , Na 6 P 4 O 13'  Na 12 P 10 O 31  and Na 8 P 6 O 19 . The air may be enriched with oxygen, water or steam may be supplied, and the added salt may itself be a phosphate such as tricalcium phosphate or phosphate rock when additive compounds are to be formed. The process is applicable to the production of other metal phosphates such as aluminium, magnesium, lead and zinc. Apparatus for carrying out the process, is shown in Fig. 1, while Fig. 6 shows the condition for the production of droplets of molten phosphate in the centre of the furnace. Molten yellow phosphorus and air are introduced into one end of the furnace through a header 8 together with a salt of a metal as indicated above and steam. The molten phosphate generated is discharged through a header 9 while phosphorus pentoxide gases or mist are sprayed with water or dilute sodium phosphate solution from a pipe 24 and drawn through a filter 10 by a fan 12. The solution of phosphoric acid or sodium phosphate obtained may be returned to the furnace through the pipe 15. The furnace may be of square or polygonal form, as shown in Figs. 6, 7, 8 to assist in carrying round the molten material. Specifications 495,487 and 505,321 are referred to.

Title: Improvements in or relating to siloxane-containing compositions of matter
IPC: C08K7/12
Filed: 1950-04-26
Abstract: A composition for moulding brake and clutch linings comprises asbestos, a physical mixture of lead sulphate and lead monoxide and a partially condensed cohydrolysate of a mixture of 30-10 mol. per cent of an ethyl silicon trihalide and 70-90 mol. per cent of a phenyl silicon trihalide.  The partially condensed siloxane comprises 5-25 per cent by weight of the whole composition and the mixture of lead compounds preferably 25-60 per cent of the composition, the lead sulphate/lead monoxide molar ratio being 0.4-1.1 : 1.  1-5 per cent of graphite and 2-10 per cent of an elastomeric copolymer of butadiene and acrylonitrile as plasticizer may also be included.  The siloxane may be prepared by adding the mixture of substituted silicon halides in a non-aqueous solvent to an aqueous medium which may also contain, e.g. alcohols, ketones, hydrocarbons or mixtures thereof and basic materials such as sodium carbonate to control the hydrolysis rate. Either the resulting resin solution or the resinous cohydrolysate obtained by removing the solvent may be used in making the compositions.  When using the butadiene-acrylonitrile copolymer the ingredients are mixed, made plastic with methyl ethyl ketone, heated to remove solvent and the resulting mass comminuted and moulded.  The asbestos may be in the form of loose fibres, paper or cloth, and the lead compounds in finely divided form.  Asbestos cloth may be dipped in a slurry of the other materials and a solvent for the siloxane, dried, dipped again, dried, assembled into a laminate and moulded.  Triethanolamine may be used as curing catalyst for the siloxane and sulphur as curing catalyst for the butadiene-acrylonitrile copolymer.  Examples are given of various compositions using a cohydrolysate of 20 mol. per cent ethyl silicon trichloride and 80 mol. per cent of phenyl silicon trichloride, together with dynamometer test figures for wear and coefficients of friction at various temperatures.  For comparison examples are given: (1) omitting lead sulphate; (2) omitting lead monoxide; (3) using basic lead sulphate instead of a mixture of sulphate and monoxide.

Title: Improvements in or relating to apparatus for detecting ionizing radiation
IPC: G01T1/18
Filed: 1955-04-14
Abstract: 795,036. Radiation detectors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 14, 1955 [April 16, 1954], No. 10781/55. Class 40 (3). In radiation detecting arrangement in which a counter tube produces both " main " and escape pulses a second tube is provided responsive to radiation released during occurrence of the escape pulse to enable either the main or escape pulses to be selected. As shown, radiation impinges on detector tube 13 which produces both the main and escape pulses. Tube 20 is positioned to respond to the radiation produced by tube 13 during the escape pulses but is shielded from the direct source, a filter 22 being between the tubes if desired. Both tubes are connected to circuit 33 which functions as a coincidence circuit or anti-coincidence circuit according as switch 39 is in its lower or upper position. If the circuit is functioning as a coincidence circuit, tube 33 is biased to cut off. The escape pulse from tube 12 and the response to the escape pulse from tube 20 are applied to the suppressor and control grids respectively. The gate opens for the escape but not the main pulses. As an anti-coincidence circuit, tube 33 is biased so that incoming pulses pass right through. The pulses from tube 20 are inverted however so that they cancel the escape pulse at tube 33 while the main pulses pass right through. An arrangement is described with reference to Fig. 4 (not shown) in which a detector responsive to incident radiation forms the central one of a bundle of detectors, the remainder of which are responsive to the escape pulses. A screen with an aperture ensures that the incident radiation reaches only the end of the " main " detector.
