Abstract: 8.                              Abstract A method of cooling a mould A method of cooling a mould in a glassware forming machine wherein an intermediate support (26) supports a mould portion (10) and defines a space (36) which serves to insulate a movable support (14) of mould opening and closing mechanism of the machine from the mould portion (10). The mould portion (10) is cooled by blowing air into the space (36).   The air blown into the space (36) increases the insulating effect of the space (36) and also can be blown through an aperture (40) in the intermediate support (26) on to the mould portion (10) so as to cool that portion of the mould portion (10).

Abstract: EXTENDED RANGE SPEED CONTROL FOR DC DRIVE        ABSTRACT OF THE DISCLOSURE         A speed control for a DC motor drive having regenerative braking and field reversing is able to operate in the forward and reverse direction at speeds in excess of motor base speed, i.e. in excess of a speed corresponding to rated voltage and full motor field.  A sensor provides a signal representing armature current and from this a signal is derived representing IR drop in the armature.  A sensor provides a signal representing voltage applied to the armature. The difference between these two signals represents counter emf and the counter emf signal and the main control signal (the difference between desired speed and actual speed) is used to control the power supplied to the field winding to reduce the field strength and permit operation in excess of motor base speed.

Abstract: ABSTRACT       A method of determining the difference between the actual temperature of a heated pressurized fluid flowing in a closed system and its saturation temperature under the conditions of pressure and flow rate.  First, the temperature of the liquid is taken.  Second, the pressure required to produce saturation at this temperature is read from a previously known saturation curve.  Third, the pressure of the liquid is measured.  Fourth, the difference between the measured liquid pressure and the saturation pressure is added to the saturation pressure.  Again using the same saturation curve, from the result achieved in step 3, the saturation temperature corresponding to the sum of these pressure values is obtained.  Finally, the actual liquid temperature is subtracted from the indirectly determined saturation temperature to determine how much hotter the liquid can become before it reaches saturation temperature. This is an improvement over the prior art which includes additive errors from temperature and pressure measuring devices having broad ranges.

Abstract: A B S T R A C T            In the production of alloys, particularly Al alloys, by a continuous casting process a supplementary alloy stream is continuously fed into a main metal stream running to the casting mould.   The supplementary alloy stream preferably amounts to 1-20% of the main metal stream and has a liquidus temperature above the temperature of the main metal stream so that on contact with the main metal stream, intermetallic phases are precipitated very rapidly as a result of the high chill rates.           This mode of casting reduces the risk of coarse primary particles when casting alloys of high alloying element content.   The supplementary alloy stream need not be based on the same metal as the main metal stream.   The method is considered suitable for the addition of various metals, such as Zr, Mn, Cu, Fe, to aluminium and aluminium alloys to overcome a variety of difficulties and to produce alloy products of improved properties.

Abstract: ENZYME CHROMATOGRAPHIC IMMUNOASSAY                   ABSTRACT OF THE DISCLOSURE Chromatographic immunoassay employing a specific binding pair member and a label conjugate which delineates a border whose distance from one end of the chromatograph relates to the amount of analyte present.  By combining the label conjugate and sample in a solution and immunochromato-graphing the solution, or employing a combination of enzymes, one enzyme being the label and the other enzyme affixed to the chromatographic support, the position of the border defined by the label can be related to the amount of analyte in the sample solution.          Preferably, an immunochromatograph is employed having both a specific binding pair member and an enzyme affixed to the support.  A sample is chromatographed and the amount of analyte is determined by (1) contacting the chromatograph with a second enzyme conjugated with a speci-fic binding pair member which binds to the chromatograph in proportion to the amount of analyte bound to the chromato-graph, or (2) including the second enzyme conjugate with said sample, resulting in a defined border related to the amount of analyte in the sample.  The two enzymes are related in that the substrate of one is the product of the other, so that upon contact of the chromatograph with appopriate reagents, a detectable signal develops which permits detection of the border to which the analyte traveled.  This distance can be related to the amount of analyte present in the sample.
