Abstract: The present invention is a serial to parallel data conversion method and device where new serial data are stored within a first n-bit register prior to presentation at an n-bit parallel output. Subsequently, additional data are stored within a second n-bit register while the data stored within the first register are presented at the parallel output. Data storage and data presentation are thereafter alternated, thereby eliminating the problem of setup time seen in prior art.
Abstract: The present invention relates to a mounting of carbon electrodes on a holder of an arc lamp used as a light source for a weatherometer or a lightfastness tester. In the holder, one end of the carbon electrodes and the holder are threadedly connected with each other.
Abstract: A carbon arc lamp for use in a light fastness tester and other similar testers, and having a metal rod extending from a carbon electrode mounting part in the upper part of the lamp down to a point just below an upper metal plate. A portion of the rod is engaged by a ring clutch which is connected to an automatic feed control for the carbon electrode. The lower end of the metal rod has the upper end of the carbon electrode mounted thereon by a threaded connection.
