Abstract: The invention relates to a circuit and a method adapted for measuring and digitizing the value of a resistance. The circuit includes and A/D converter operating in accordance with a charge balancing principle, and a resistance network connected to the A/D converter so that the resistance is both a component of the A/D converter and of the resistance network. The A/D converter and the resistance network are interconnected in such a manner so as to permit only a purely resistive measurement. A processor is connected to the A/D converter for obtaining a composite measured resistance value from a plurality of individual measured resistance values. The method according to the invention permits accurate (or precise) resistance measurements having a high degree of resolution of an order of magnitude of 105 points. The method is applicable in particular for temperature measurements, for examples in calorimeters or in precision scales, but also in other resistance measurements.

Abstract: The disclosure relates to a method for operating an ion source having a filament-cathode and an anode. Direct current electrical power is supplied between the anode and the filament-cathode characterised by substantially constant arc current therebetween and varying arc voltage on the filament-cathode. Direct current electrical power is supplied across the filament-cathode. The value of the arc voltage is monitored and the magnitude of electrical power supplied to the filament-cathode is altered in response to detected changes in the arc voltage to return the arc voltage to substantially a present reference value. The step of supplying power between the anode and the filament-cathode is done by monitoring the value of arc current flowing between the anode and the filament-cathode, deriving an arc current error signal as a function of the difference between the monitored arc current value and a present arc current demand signal, and altering the voltage supplied to the filament-cathode as a function of the arc current error signal until the monitored arc current is equal to the arc current demand signal.

Abstract: The invention relates to a method of bending a glass sheet to be tempered as well as to a glass sheets bending and tempering apparatus. An array of conveyor rollers in a glass sheets bending and tempering section is adapted to be curved around an axis of curvature transverse to the traveling direction in a manner that, beginning from a horizontal plane, the plane of a roller line curves with a continuously diminishing radius of curvature until the final radius of curvature is reached. During the curving process, the tangent of the mid-portion of a curved conveyor section is maintained substantially in a horizontal plane. Thus, each point in a glass sheet curves substantially at the same rate over the entire glass sheet area and, hence, local rapid deformations do not occur. During the curving process, a glass sheet is maintained in motion by means of the rollers of a curved roller conveyor.
