Title: Method for the production of glass
IPC: C03B13/12
Filed: 1970-10-01
Abstract: 1331635 Producing ribbon glass TRANSGLAS PATENT-UND LIZENZWERTUNGS AG 1 Oct 1970 [3 Oct 1969 17 June 1970] 46742/70 Heading C1M In the production of ribbon glass and while the glass has a viscosity of between 10<SP>3</SP> and 10<SP>10</SP> poises, the glass is stretched by an amount corresponding to at least 30%, in at least one glass stretching zone, and is subjected to at least natural cooling in said zone. This may be achieved by allowing glass to flow over a lip 3 of a glass-melting furnace and then to flow vertically in a compartment 11 so that the glass ribbon is stretched under its own weight. The temperature of the glass flowing over the lip is sensed by thermocouples and controlled by electrical heating elements 13 to ensure that its viscosity is about 10<SP>3</SP> poise. Cooling devices 16, 17 provide additional cooling of the ribbon as it leaves the compartment 11. Alternatively the stretching may be carried out by conveying a glass ribbon from a furnace to a stretching zone defined by two pairs of rollers 20, 21 and 26, 27 the second pair rotating at a higher velocity than the first. A third pair of rollers 27, 28 may also be used thus defining a second stretching zone. The thermal losses from the glass are controlled so that the temperature fall in the first zone is 300‹ C. and in the second zone 150‹ C. Wire glass may be produced by embedding metal wires in the glass at the beginning of the production path. A glass containing in percentage by weight SiO 2  69; alkali metal oxide 14; alkaline earth metal oxide 12; trivalent element oxide 1À4b, B2O 3  1À94, the remainder being TiO 2  and SO 3  is disclosed.

Title: Method and apparatus for the production of liquefied petroleum gas mixtures in the gas phase
IPC: F17C7/04
Filed: 1974-11-05
Abstract: 1492761 Mixing liquified gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 5 Nov 1974 [7 Nov 1973] 47798/74 Heading B1C A method for the production and distribution of liquefied petroleum gas in the gas phase comprises mixing in the liquid phase two LPG's of different volatility (for example propane and butane) so that the saturated vapour pressure of the mixture does not exceed a predetermined value P 0  which is equal to or greater than the consumption pressure P u , vapourising the mixture, and reducing the pressure of the gas so obtainable to P u . The method renders subsequent re-condensation unlikely. An apparatus comprises a mixing vessel 16 to which LPG of lesser volatility (e.g. butane) is supplied from a container 12 through a valve 24 controlled to maintain the liquid level in the vessel 16 between level sensors 54, 56. A LPG of greater volatility (e.g. propane) is supplied from a container 14 through a valve 38 which is controlled by a vapour pressure sensor 58, which senses the drop in saturated vapour pressure caused by the supply of butane and causes propane to be supplied until the saturated vapour pressure in the vessel reaches a predetermined value P 0 . The mixed liquefied gases are recirculated, preferably through a heat exchanger 52, and returned as droplets to the vessel 16 in order to equalize temperatures and pressures in the vessel and maintain it near the ambient temperature; the propane supply line 36 is advantageously connected to the recirculation line 50. The mixed liquefied gases are supplied to a vapourizer 18 and thence to a pressure regulator 20 arranged to supply gas at the supply pressure P u  to the supply line 10. A fall in the ambient temperature will cause a greater proportion of propane to be supplied in order to maintain the pressure P o , and vice versa. Should the fall in ambient temperature be so great that the pressure P o  cannot be reached, the valve 38 will be closed when the liquid level in vessel 16 reaches a maximum level sensor 60. In a modification the level sensor 56 may be dispensed with and butane supplied in a fixed time. In another modification the control of the valves 24, 38 may be reversed, so that propane is supplied until the liquid level reaches 56 and the vapour pressure is then reduced to P o  by addition of butane. In another embodiment see Fig. 5 (not shown) the vapourizer and mixing vessel are combined.

Title: Measurement of the deflection of a workpiece surface by optical interference methods
IPC: G01N21/892
Filed: 1975-11-24
Abstract: 1488536 Measuring deflection by optical interference KRAUTKRAMER GmbH 24 Nov 1975 [4 Dec 1974] 48172/75 Heading G1A Apparatus for sensing the deflection of a workpiece surface 5 resulting from accoustic energy applied thereto comprises laser 1 whose beam 9 after reflection from surface 5 is split by beamsplitter 2 into portions 9a, 9b which positionally coincideon sensor 7, portion 9b being delayed due to the distance 11. Surface 5 is subjected to accoustic energy at 1 to 10 Hz. The strength of the signal from photo-cell 7 depends on the phase difference of 9a to 9b, which varies according to the deflection of surface 9 during the delay time. For the phase difference over the photo-cell of diameter d to be constant, the angle between portions 9a and 9b at the photo-cells <#/2/d. For this the distance from surface 5 to splitter 2 is at least 5S for a diameter of 1 cm, or a telescope lens system with an aperture at the common focal point is interposed between 5 and 2 or mirror 10 and 2. The delay path may be folded by a pair of facing mirrors. Length S may be modualted Piezoelectrically at a frequency f 1  higher than the accoustic frequency f 2 , so that the optimum path period occurs several times within the vibration period and the photo-cell output is at frequency f 1  modulated by f 2 . The broken lines of Fig. 6 show the light beam of a second interferometer used to maintain a constant length S. If the distance of the delay path S via mirrors 2a, 18a, 18b and 2b alters, illumination at photo-cell 19 alters, giving a signal via amplifier 20 and filter 21 to Piezo-electric element 24a  causing the motion of mirrors 24b to restore the illumination of photo-cell 19. Alternatively S may be kept constant by the Piezo-electric means moving mirror 18 relative to a fixed reference.
