    Abstract: A heat-activatable polymer resin is applied as an overcoat to wire-scribed interconnection circuit boards after producing the wire-scribed conductor pattern in order to prevent drifting of the wire conductors during further processing of the boards.

    Abstract: ® An alternator for use in a brushless DC tachometer is claimed which produces an output voltage with a trapez oidal waveform. The alternator includes a three phase toroidal winding on a slotless core. The windings are concentrated rather than being distributed. The rotor includes high intensity permanent magnets configured to provide uniform flux density over a large segment at least equal to a commutation increment.

    Abstract: A color monitoring system (32, 33) is disclosed which is capable of distinguishing between colors used in color-coding schemes or between colors that indicate acceptable and unacceptable quality in products to be sorted or toleranced as part of a manufacturing process. The system utilizes parallel measurements (10-18) in a number of spectral bands of the reflectance from samples (7) being tested. Simultaneous complete referencing (22-30) for each spectral band of reflectance is provided to compensate for variations in the intensity and spectral output of the light source (1) used for illumination of samples (7).

    Abstract: An aspherical surface generating method and apparatus which optimizes the path of a moving cutting tool tip to fit a given aspherical surface of revolution to be cut on a rotating work piece engaged by the moving tip. The apparatus is a modified spherical generator, the modifications and control of which adapt it to continuously match the curvature of the path of the moving cutting tool tip to that of the given aspherical surface of revolution by adjusting the dynamic machine center in the direction of the evolute of the curve, i.e. along the locus of the radius of curvature of the given surface at the tool tip.

    Abstract: Systeme spectro-photometrique en couleur utilisant un tube d'eclair au xenon (1) dans lequel le tube d'eclair (1) est actionne dans des conditions provoquant la regeneration des electrodes (3, 4) plutot que leur deterioration lors de l'utilisation et dans lequel les mesures de lumiere a de differentes longueurs d'ondes sont corrigees en fonction de deux mesures de reference permettant de compenser aussi bien les changements d'intensite que les decalages spectraux de la lumiere emise par le tube d'eclair (1). Un condensateur (10) se decharge au travers du tube d'eclair (1) au moyen d'une inductance (12) qui reduit la crete et prolonge la duree du courant de decharge.
