Title: Process and system for supplying an emulsion of liquid fuel and water to a heating burner
IPC: F23D11/16
Filed: 1971-06-02
Abstract: 1325954 Supplying emulsion of liquid fuel and water to burner ELF UNION and ATE LIERS DES CHARMILLES SA 2 June 1971 [2 June 1970] 18627/71 Heading F4T A system for supplying an emulsion of liquid fuel and water to a burner B capable of operating at a low heating rate and at least another higher heating rate is characterized in that, when normal heating with the emulsion is stopped (i.e. the burner is extinguished), at least a part (in the case shown, low heating rate jet 1) of the burner B is connected to a discharge 40, 10, without pressure, to the liquid fuel source 6 and the burner is supplied with liquid fuel alone under pressure to expel the emulsion through the discharge and fill the burner with liquid fuel alone with which, after closing the discharge, the burner is re-ignited before resuming normal emulsion supply. Liquid fuel and water are supplied by circuits I and II respectively via pressure regulating means, heaters 13 and 29, a mixer-emulsifier 3 and a pump 4 to the burner B. Electrically-operated valve 35 allows water supply during normal operation but closes when the burner stops, and electrically-operated discharge valve 41 is closed during normal burner operation. The higher heating rate is achieved by using jets 1 and 2 in combination, as shown, or by adjusting flow modulation means associated with a single jet (Fig. 2, not shown). A further fuel pump 7 delivers liquid fuel to a forced-feed loop 9, 10 having a pressure regulator 11 downstream of which the discharge conduit 40 joins conduit 10.

Title: Aqueous colloidal dispersions of polytetrafluoroethylene and the formation of shapedstructures therefrom
IPC: D01F6/12
Filed: 1950-07-27
Abstract: An aqueous colloidal dispersion of polytetrafluoroethylene containing at least 5 per cent and preferably 15-75 per cent of polytetrafluoroethylene and which is capable of being extruded and coagulated to form filaments of tensile strength greater than 25 lbs./sq. inch, is made from particles of polytetrafluoroethylene having at least one dimension less than 0.1 micron of which at least 5 per cent of the particles have an elongated ribbon-like shape of width less than 0.07 micron and a ratio of length to width greater than 5 : 1.  The dispersion may be made by polymerizing tetrafluoroethylene in aqueous media, under superatmospheric pressure and temperature, in the presence of a catalyst, e.g. ammonium persulphate and a dispersing agent consisting of the ammonium or alkali metal salts of a polyfluoroalkanoic acid of the formula H.(CX2-CX2)n-COOH, where X is fluorine or chlorine and at least half of the X's in each (CX2-CX2) unit are fluorine and n is an integer from 3 to 10, e.g. potassium or ammonium hexadecafluorononanoate, and ammonium eicosafluoroundecanoate.  Optionally the aqueous media may contain a hydrocarbon stabilizer, e.g. paraffin wax.  The dispersion may be cast or extruded into shaped articles such as fibres, filaments, tapes, ribbons and films.  In the preparation of shaped articles by extrusion, coagulation to the gel structure may be effected by a dry or wet-spinning process and the gel subsequently sintered above 327 DEG  C.  In the dry spinning process the medium may be air or gaseous sulphur dioxide, hydrogen chloride or fluoride or carbon dioxide.  In the wet process the medium may be a solution of hydrochloric, sulphuric, phosphoric, nitric, dichloroacetic or oxalic acid or an alkali salt such as sodium chloride, sulphate, acetate or dihydrogen phosphate and mixtures.  Prior to heat-hardening the gel structure may be coloured by passing the gel through a bath containing chlorinated copper phthalocyanine, or a violet vat dye, or ferric nitrate, or colloidal silver, or by precipitating a pigment in the gel, e.g. by treating the gel with lead nitrate and then potassium chromate. Fillers and reinforcing agents may also be precipitated in the gel structure.  The filaments may be cold-drawn.  Oriented gel fibres may also be obtained by flowing the dispersion through a tube into a coagulating medium. Specifications 631,504 and 689,400 are referred to.ALSO:Dyed polytetrafluorethylene fibres, filaments, films, tapes and ribbons are made by forming the articles in gel form from polytetrafluorethylene dispersions (see Group IV (a)), passing the gel through a bath or baths containing a dye, e.g. chlorinated copper phthalocyanine or a violet vat dye, or ferric nitrate, or colloidal silver, or forming a pigment in the gel, e.g. by treating it with lead nitrate and then potassium chromate, and then sintering above 327 DEG  C.

[Class 135.] Valves controlled by pilot or relay valves.-Audible or visual signals on a train are initiated by a track contact which causes an air impulse to be given to open the signal operating means to the train vacuum source and this last then maintains the signal in operation indefinitely. The apparatus shown comprises a diaphragm c formed with small ports m so that normally a vacuum exists on both sides due to the connection with the train pipe j. At a track contact a spring or like valve (not shown), is momentarily opened to admit air by the pipe n to the underside of the diaphragm c which rises and by its spindle q opens a valve h to connect a siren i with the vacuum pipe j. The diaphragm spindle by means of a lever s also lifts a valve e to maintain the underside of the diaphragm at atmospheric pressure so that the signal persists until this valve e is manually closed, whereupon the vacuum beneath the diaphragm is gradually restored through the ports m. The diaphragm ports m are closed by engaging a valve seating p when the diaphragm rises.
