Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B17/00
Filed: 1961-03-29
Abstract: <FORM:1010913/C1/1> In the manufacture of sheet glass having a predetermined thickness, a ribbon of glass sufficiently stiff to be gripped and to constitute a barrier to resist transmission of tractive force, is advanced along a bath of molten metal, the ribbon is gripped to control its velocity and then progressively heated to a transitional plastic state, the plastic glass then being reduced in thickness by longitudinal tractive <FORM:1010913/C1/2> force, the ribbon of glass stabilized at the desired thickness and cooled to permit removal unharmed from the bath.  The glass may first be formed into a buoyant body of glass as in Specification 893,663 and then cooled to stiffen the glass.  Molten glass 11 is fed from a furnace 1 under a tweel 2 over the lip 4 of a spout between side joint 5 either between driven rollers 6, 7, Fig. 2, or under a gate 10, Fig. 3, to form a layer 28 on the surface 16 of a bath 12 of molten tin in a tank 13, 14, 15, the tank being enclosed by a roof 17 and extension 24 and a non-oxidizing atmosphere maintained over the bath 12 through pipes 20a.  The layer 28 of glass is heated by heaters 26, 27 to about 1000 DEG  C. for soda-lime glass to form a buoyant body 30 between the end wall 18 and a partition 29.  Between partitions 29 and 31, the glass is cooled to about 700 DEG  C. by water cooled boxes 32 extending across the tank to give a stiffened ribbon 34 which is gripped by two pairs of edge rolls 35, 36, at right angles to the travel of the ribbon, driven to control the velocity of the ribbon 34, which will be either the same as or slightly greater than that of the buoyant body 30 which is thereby slightly tapered.  In a third zone between partitions 31 and 37, the ribbon 34 is progressively reheated to about 850 DEG  C. to give plastic glass 40 which is attenuated by the tractive force from driven rollers 46 and 47 (not shown) outside the tank.  In the final zone between partition 37 and end wall 15, the width of the ribbon 45 is controlled by two or more pairs of oppositely disposed and angled edge rolls 41, 42 which grip the edges of the ribbon and thermal regulators cool the glass to about 650 DEG  C. at the end wall 15 so that the glass will not be harmed by the rollers 46, 47.  Specifications 769,692, 1,010,914 and 1,010,915 are referred to.

IPC: H01B1/08
Filed: 1948-05-03
Abstract: 648,423. Non-metal resistances. STANDARD TELEPHONES & CABLES, Ltd. May 3, 1948, No. 12088. [Class 37] Relates to the manufacture of non-stoichiometric semi-conductors, for example, titanium dioxide resistance bodies deficient in oxygen. According to the invention as part of the manufacture, samples of the produced material are subjected to thermo-electric analysis to determine the concentration of impurity centres in the crystals and the homogeneity of the agglomeration. Apparatus for this purpose is shown, Fig. 1, wherein electrodes in the form of brass discs 6, 7 are clamped against a titanium dioxide rod 1 separated from supports 2, 3 by mica sheets 4, 5. Each brass disc, Fig. 2, comprises a temperature-measuring thermo-couple 8, 9 and nickel wire 10. Heater 11 operated from a variable auto-transformer heats disc 6 and tubes 13, 14 adjacent disc 7 are filled with solid carbon dioxide or liquid air. The rod 1 is surrounded by asbestos and a voltmeter measures the E.M.F. developed between the wires 10. The subsidiary heater 15 along the rod 1 is disconnected and voltage measurements made to determine the average concentration of impurity centres, i.e. the average constitution of the micro-crystals within the agglomerate. The heater 15 is then switched on and placed at various positions a, b, c, to set up asymmetrical temperature distribution and E.M.F. measurements made to determine to what extent the sample departs from homogeneity, i.e. the heterogeneity in the micro crystals of the agglomerate. Full test instructions and related formulµ are given in the Specification. The curves given, Fig. 3 (not shown), show that the sample 1 in Fig. 1 is heterogeneous. Modifications in the manufacture are then made and a further sample tested. This procedure is continued until a given sample possesses substantially the required degree of impurity, i.e. the required excess or deficiency of oxygen and at the same time impurity centres all equal in impurity content throughout the agglomerate.

Abstract: 1309066 Selective signalling BURROUGHS CORP 29 April 1971 [12 May 1970] 12127/71 Heading G4H [Also in Division H1] An encoding device comprises means for generating a set of individual magnetic fields, means responsive to the generating means for completing circuit paths, the generating and responsive means being radially arranged on opposing surfaces, these surfaces being relatively positionable with respect to shunting means having a plurality of shaped apertures therethrough for selectively shunting the set of magnetic fields. In the exploded view of Fig. 2, insulator discs 45, 47 each bear 3 radially-arranged permanent magnets 54 facing 3 radially-arranged reed switches 67 on discs 63, 65, respectively, to close them selectively according to the positions of respective interposed apertured magnetic shunt discs 55, 57. Discs 55, 57 are rotated together by "decimal-point" dial plate 93 according to the required decimal point position (counting from the low-order limit of the storage) in a calculator memory holding a number entered from a keyboard or the result of a calculation and capable of controlling printout. Discs 63, 45 are rotated together by "round-off" dial plate 103 according to the number of decimal digits after the decimal point to be retained. Discs 47, 65 are fixed stationary. The reed switches 67 on disc 65 give a binary-coded indication of the required decimal point position, and those on dise 63 give a binary-coded indication of the number of low-order decimal digits to be rounded off, i.e. made zero (since the movement of disc 55 by dial 93 and discs 63, 45 by dial 103 effects a subtraction between the two dial settings). Detents prevent dial 103 having a negative setting or a larger setting than dial 93. Modifications: (a) the reed switches may indicate the above quantities plus one, (b) the reed switches on disc 63 (round-off) may indicate the number of digits after the decimal point to be retained, the number of digits to be rounded off being determined in the calculator.
