Title: Method for detecting for imperfections in inert coatings on metal assemblies
Inventor: GRIMWOOD GEOFFREY LUTHER
IPC: G01N27/20
Filed: 1990-04-26
Abstract: A method and apparatus for testing, in situ, for imperfections in an inert coating (2) of a moving metal component (1) of an apparatus (e.g. a metal basket of a centrifuge) involves covering the inert coating (2) with an electrically conductive liquid (33), applying an electrical voltage across the inert coating (2) while the apparatus is operational, monitoring the current or applied voltage, and utilising the measured current or voltage to provide an indication of the condition of the inert coating. If the coating is defective, the conductive liquid will find its way into any flaws or imperfections, thereby providing a path of lower electrical resistance. Various arrangements for applying the voltage are described and for monitoring the current or voltage. This latter may be achieved by connecting an inductance in parallel with a capacitor constituted by the metal basket (1), coating (2) and conducting liquid (33) to form a resonant circuit and monitoring current flow, connecting the capacitor in a bridge circuit, or monitoring current flow. <IMAGE>

Title: Binary counting circuit
Inventor: BIRT L A
IPC: H03K23/66
Filed: 1990-06-28
Abstract: A binary counting circuit comprises a binary counter C having selected ones of its outputs connected via switches S0-S11 to respective inputs of a logic circuit NAND, and other inputs of this logic circuit being maintained at a predetermined logic level, so that the logic circuit produces an output signal at a predetermined count. However, diode means D3 responds to each input pulse to the counter to disable the logic circuit output signal until after the triggering edge of the input pulse corresponding to the predetermined count. As shown, input pulses are used to produce fixed-length pulses at the output of a monovibrator MV1, and a resetting output of the circuit taken via a further monovibrator MV2 is inhibited until the arrival of trailing edge of a desired pulse from the first monovibrator MV1. A timing circuit and multiplying circuit are described with reference to Figs 3, 4 (not shown). <IMAGE>
