Patent GB-969907-A (GB)
Title: Method of and apparatus for the thermal conditioning of molten glass before its shaping
IPC: C03B15/02
Filed: 1961-05-17
Abstract: The temperature of molten glass, during its travel in a tank towards and in the region of a point at which it is extracted to be shaped, is regulated by being fed over and in contact with the upper surface of a subjacent bath of molten material other than glass, heat being taken from the glass by the molten material at a point at which the glass is to be cooled and restored to the glass from the molten material at another point at which the glass is to be heated.  As <PICT:0969907/C1/1> <PICT:0969907/C1/2> <PICT:0969907/C1/3> <PICT:0969907/C1/4> shown in Figs. 4 and 5, molten glass is flowed from a furnace 2 to the drawing chamber 6 over a bath 4 of tin, lead or an alloy of either with copper, the bath 4 being bounded by a sill 3, end wall 8, the side walls 7, 71 of the drawing chamber 6 and an external channel 22 joined to the main bath by apertures 23, 24 in side wall 7.  The glass sheet 10 is drawn from the gather 13 over a draw bar 12 which extends above the bath 4 and may have apertures 14 to assist the flow of molten glass.  In this embodiment, the bath 4 is divided by baffles 16, 161 extending alternately from opposite side walls 7, 71 to give compartments 17 through which the molten material is flowed by means of a screw 25 in the external covered channel 22. The shaft 26 of the screw 25 extends either through the side wall, where it is driven by motor 27 through a variable-speed gear, or obliquely upwards through the roof 29, Fig. 7. The shaft 26 may be enclosed by a jacket 30 having a pipe 31 for the introduction of an inert or reducing gas which prevents oxidation of the molten material and maintains a superatmospheric pressure in the channel 22. A floating layer 32 of coke or graphite grains may also be provided to prevent oxidation.  A barrier 60 upstream of the screw assists flow of the material.  As shown in Fig. 13, molten glass is flowed from a furnace 2 over a sill 3 and bath 4 of molten material to a feeder 41 whence glass is fed in gobs downwardly, as by a plunger. The bath 4 is subdivided by baffles 42, 43 and extends in a passageway 481 around the extraction zone 47 and through an outer channel 44 in which is a propeller 45 driven from motor 27 through variable-speed gear 28, giving a flow to the molten material as shown by the arrows. In Figs. 1-3, not shown, it is stated that the renewal of the surface of the bath 4 by convection currents is sufficient to withdraw and restore heat to the molten glass.  In all cases, heaters and coolers may be used to assist the process.  As shown in Fig. 4, electrical heating resistors 54 and ducts 55 of hairpin form for heating or cooling media may be used or gas burners in a casing let into the wall of the channel. Thermocouples 56 are used for regulation of the temperatures.

Title: Improvements in or relating to apparatus for measuring the weight of liquid
IPC: G01F23/26
Filed: 1951-07-30
Abstract: 695,074. Electric tests and measurements. LIQUIDOMETER CORPORATION. July 30, 1951 [Aug. 4, 1950], No. 17982/51. Class 37. Apparatus for determining the weight of liquid in a tank comprises a capacity gauge of the type described in Specification 693,600, e.g. two concentric cylinders immersed in the tank, so that the volume of liquid may be ascertained from the resultant dielectric constant of the test capacitor, and the capacitor is included in a bridge circuit wherein an electrical quantity is created representing the density of the liquid on the assumption that the relationship between density D and dielectric constant K is K=aD+b, a and b being constants, the bridge being automatically balanced by a reversible 2-phase motor fed with the unbalance voltage on one phase, driving a potentiometer to maintain balance, and also a counter mechanism which indicates weight of liquid in the tank. Fig. 1 represents the basic electrical circuit of the invention. The two halves of the secondary winding of a transformer 2 constitute two arms of a bridge, the test capacitor Ct being the third arm, and the fourth arm being a condenser Cc in parallel with a condenser Cr fed from the slider 14 of a potentiometer 12 across one half winding. The capacity of Cc is equal to that of the test capacitor Ct when empty, Co. The weight of the liquid in the tank is then proportional to the fraction m of the potentiometer 12 feeding condenser Cr, when the bridge is balanced, if Cr=<SP>K-1</SP>/ K -banCo, where n is a con- K-b stant. Expanding this term by Taylor's series, it is shown that Cr#(α+#K)nCo, where α and # are constants. In an embodiment (Fig. 3), Cr is constituted by a fixed condenser Cd (=αnCo) in parallel with a condenser Cs formed by spaced plates immersed in the tank so that Cs=#KnCo. The unbalance voltage of the bridge is fed into an amplifier 22 whose output is taken to a 2-phase motor 26 which moves the slider 14 of potentiometer 12 to balance the bridge, and also operates an indicator 42, which is made to read correctly when the tank is empty by adjusting a potentiometer 44, and when full by adjusting a variable resistor 48.

A tubular blind roller 46 has a removable end plug 10 with a plurality of different length, longitudinal grooves 22 terminating in an end wall 22a which limits the extent to which the plug 10 may be inserted into the roller 46 so that the effective roller length may be adjusted in dependence upon which groove 22 is selected. In one embodiment, Figs. 1, 6, the plug 10 comprises an end disc 14 with a pin 16 fitted into the open end of a tubular body 12 formed by rolled sheet metal with a lap joint 18 including interengaging tongues 19, 20 and slots which allow a diametric contraction of the plug 10 when fitted. The roller 48 comprises rolled sheet metal with a longitudinal lock seam 48 the end of which forms a stop to be engaged by an end wall 22a. A secondary stop comprises a pair of diametrically opposite tabs 50 bent in from the roller walls to engage the end of the plug 10 if it is inadvertently knocked too far into the roller 46. In another embodiment, Fig. 8, the plug 110 is of moulded plastics and has two series of different length grooves 120-128, one groove of each series having an associated similar length groove (120<SP>1</SP>-128<SP>1</SP>, Fig. 10) in the other series. The plug 110 has an associated collar 210 with a pair of diametrically opposite projections 130, 130<SP>1</SP> which slidably engage a selected pair of grooves, e.g. 120 and 120<SP>1</SP>. The extent of movement of the collar 210 on the plug 110 is limited by engagement of the projections 130, 130<SP>1</SP> with end walls of the grooves. When fitted into a tubular roller (134) the collar 210 bears on the end edge of the roller (134). The tubular body 112 of the plug 110 is flared and longitudinally split at 124 to permit resilient, inward deformation when fitted.

Title: Improvements in recovery of olefin polymers from solution
IPC: C08F10/00
Filed: 1957-06-07
Abstract: Solid polymers of mono- and di-olefines are precipitated from an organic solvent solution of the polymers by removing heat from the solution at a sufficient rate to provide a substantially uniform rate of temperature decrease therein, whereby solid polymer is precipitated and recovered.  Further amounts of polymer may be recovered from the treated solution either by the above method or by a flash technique, i.e. by passing the solution to zone wherein the pressure is subatmospheric and the decrease in temperature of the solution is substantially instantaneous.  The solid polymer may be further purified by dispersing it in hot water, subjecting the dispersed polymer to steam treatment to remove any residual solvent, and separating the polymer e.g. by a flotation technique.  The polymers may be homopolymers or copolymers of ethylene, propylene, butylene, butadiene, or isoprene.  The polymers may be those made using as catalysts hexavalent chromium with silica, alumina, zirconia, thoria, or silica-alumina, or triethyl aluminium or ethylaluminium halides and titanium tetrachloride, or the reaction product of sodium, potassium, lithium, rubidium, zinc, cadmium or aluminium with titanium or zirconium tetrachloride or tin or silicon tetrabromide.  The organic solvent may be the polymerization medium. Specified solvents are propane, isobutane, n-pentane, isopentane, iso-octane, cyclohexane or methylcyclohexane.  The cooling may be effected using cooling coils disposed in the solution, or a doubled-wall container containing a circulating cooling agent, or by mixing a cold diluent with the solution or by direct autorefrigeration, i.e. cooling by vaporization of the solvent preferably by reduction of the atmospheric pressure.  The recovery process is generally operated as part of a continuous process and the Specification contains a number of flow diagrams in which this recovery process is incorporated with the steps of making the polymers and recovering and purifying materials used in their manufacture, e.g. solvents.  Specification 804,641 is referred to.
