Title: Improvements in or relating to the control of liquid levels
IPC: G05D9/12
Filed: 1956-09-07
Abstract: 795,096. Indicating and regulating liquid levels. GENERAL GLASS EQUIPMENT CO. Sept. 7, 1956 [Feb. 10, 1956], No 27498/56. Class 123(1) Apparatus for determining and control. ling the level of liquid within a tank. especially the level L of molten glass in a glass furnace F, consists of two refractory tubes 12, 13, which are slidably mounted in sealing apertures 14, 15 in the furnace crown, the tubes being secured to racks 21, 22 whereby they can be raised or lowered. The upper ends of the tubes are connected to an air reservoir 20 by pipes 16, 17, the reservoir being supplied with air at constant pressure. Branch pipes 25, 26 lead from the pipes 16, 17 to a pressure differential indicator and controller instrument 27 from which an appropriate pressure signal is transmitted to a pressure switch 28 controlling the operation of a batch charger 30 when a change occurs in the pressure differential between pipes 16 and 17. In operation, the tube 13 is lowered until its lower open end is at such a distance from the surface of the glass that the issuing air jet is partly restricted and a back pressure is set up in the pipe 16. The tube 12 is lowered to a position several inches above the glass so that whilst any rise or fall of level will not affect the pressure in the pipe 17 the tube 12 will serve to compensate for changes in ambient furnace pressure. If the level L falls the change in differential pressure as measured by the instrument 27 causes the batch charger 30 to feed material to the furnace until the level is restored.

Abstract: 901,774. Drawing glass fibres. JOHNSMANVILLE FIBER GLASS Inc. Aug. 9, 1960, No. 27518/60. Class 56. Apparatus comprising a container for molten glass with a projection having an orifice from which a fibre can be drawn has a heat-reflective shield member to reduce radiant heat transfer from the bottom of the container to the end of the projection. Thus, hollow metal projections 75, Fig. 5, may be inserted in or made integral with the container 74 made of metal or clay refractory. A circular metal container may be heated by induction, a refractory one by gas. The reflective shield 73 is apertured to fit the projections. The shield is of precious metal, e.g. gold, silver, platinum-rhodium alloy, or of aluminium or metal-coated asbestos. The projections may be in circular rows in a circular container, the shield 73 being annular and, if required, water-cooled at its periphery. The projections may, however, be arranged rectangularly on a rectangular container heated by passage of a current, the shield 73 then being supported without touching the projections and being in sections around groups of projections. Alternatively each projection may have its own tubular shield supported on the projection (Fig. 7) or separately or formed integrally (Fig. 8). When the projections are arranged rectangularly the shields may be intersecting plates between adjacent rows of projections and parallel to their axes. A solenoid-operated device controls the feed of glass to the container preferably in the form of marbles. Separate drawn fibres are gathered to form a single thread.

Title: Process for the separation of mixtures of gases into their components
IPC: F25J3/02
Filed: 1928-09-28
Abstract: 297,842. Ges. f³r Lindes Eismaschinen Akt.-Ges. Sept. 30, 1927, [Convention date]. Separating gases by liquefaction. - The auxiliary medium which by its condensation and vaporization supplies heat to and withdraws heat from the gas mixture undergoing liquefaction and rectification, comprises a mixture of gases of different boiling points which are separated by fractional liquefaction and separately vaporized after expansion and finally recombined. For the rectification of a mixture of methane, ethylene, and propylene, the auxiliary mixture may be of methane and ethylene. The main gas is introduced at 3 into the column 1 after cooling and, if necessary, liquefaction by the separated products in a heat-exchanger. Methane is withdrawn at the point 6, and a liquid mixture of ethylene and propylene is introduced into and separated in the column 8, ethylene and propylene leaving at the points 12, 11. In the auxiliary cycle, the ethylene in the pre-cooled compressed mixture supplied at 13 is liquefied in the condenser 14 by the liquid propylene in column 8, which it heats ; the liquid ethylene is expanded through valve 16 and cools the condenser 10, passing away at 17. The gaseous methane is liquefied in the, coil 19 by the liquid at the base of column 1, and after expansion through valve 20 it cools the condenser 5 and escapes at 21. All the escaping gases are employed in counter-current beat exchange with the warm compressed gas entering the system. If separation is to be effected in more than two stages, the coil 19 may be replaced by a reflux condenser like the condenser 14. The condenser 14 may be combined with a rectification column heated e.g. by the auxiliary gas mixture. The auxiliary mixture may be replenished, or its constitution altered, by the products from the main cycle. The Joule-Thomson effect of the auxiliary gas may be utilized to produce cold in the apparatus.

Patent GB-897295-A (GB)
Title: Improvements in or relating to the production of sheet material comprising bonded fibres
IPC: D04H1/736
Filed: 1957-09-10
Abstract: <PICT:0897295/IV (a)/1> A method of forming a sheet material comprises the steps of coating a forming surface with a binding medium, setting up an electrostatic field between the forming surface and a feed apparatus for fibrous material whereby the fibrous material is transferred to the forming surface and forms with the binding medium thereon a sheet material which is subsequently removed from the forming surface.  As shown an endless metallic belt 1 passes over a series of rollers 2, 3, 4 and 5 mounted on a frame 6.  The belt is cleaned by water spray 7 and rotating brushes 8, dried by heater 9 and coated with a greasy adhesive (e.g. petroleum jelly) from reservoir 10 by rollers 11.  The belt passes over roller 2 p and then under a pneumatic and electrostatic feeder 12.  This feeder draws fibres from a reservoir by means of an air stream set up by fans 21.  The fibres pass down tube 22 through successively finer screens 23, 24 and 25 located behind the fans and the tube 22 then opens out to form chamber 26 whose bottom is formed by a grid 26a of metallic mesh.  A baffle 27 is provided to control the air currents together with tangential air jets 30.  An electrostatic field is applied between the grid and belt 1 by high tension source 31.  The belt, thus coated with fibres, passes under roll 13 to flatten the fibres and under spray 14 which adds a coating of adhesive.  The belt then passes under further feeder units (two more, 12a and 12, being shown but more may be used if required) and binder sprays whereby further layers of fibre and binder are added.  Finally the belt passes over heated rollers 3, 4 and 5 and the resultant sheet material is removed from belt 1 by doctor blade 19 and/or air blade 20.  After the web has passed through several successive stages of feeding &c., each ensuing feeding device may be immediately followed by a device (as shown at 16) whereby it is subjected to a series of transversely directed air jets, which have the effect of substantially aligning the fibres in a direction transversely of the belt, and by hot air jets (as shown at 17) whereby a measure of interstage drying is effected.  Alignment of the fibres may alternatively be effected electrostatically by passing the web under a row of electrically charged metallic points.  Interstage and final drying may be effected by infrared means.  The material of the invention may be formed upon or internally strengthened by textile or other base or reinforcing material by introducing the latter on to the belt either before any fibres are laid down or at an intermediate stage.  Specified fibres are animal hair, straw and sawdust.
