Title: Optical two-beam diagnostic device - operates with barrier filter and measuring filter insertable in each path
Inventor: SCHAUDEL DIETER E DIPL ING
IPC: G01N21/25
Filed: 1977-09-30
Abstract: A first beam from a source of light passes through a dish to a measuring element, and a second beam from the same source passes directly to a second measuring element for comparison in a comparator. The measuring filter can be moved in turn in the first or in the second path of the light beam. This reduces measuring errors by extraneous causes to a minimum and restricts the readings to comparable figures whi0h are affected only by the dish. The same lamp (1) provides the beam for the measuring path (16) and for the comparison path (17) via a mirror (15). The former passes through a condensing lens (20), and a diaphragm (2) through the dish (3) with the sample and reaches the measuring element (5). The latter goes through a diaphragm (2a) directly to a second measuring element (5a). A logarithmic processor (18) stores and compares the readings. A slide (19) carries the barrier filter (13) and a measuring filter (4) so that both can be made inoperative in each of the two paths.

Patent DE-2813062-A1 (DE)
Inventor: ROTH WALTER
IPC: H01R12/50
Filed: 1978-03-25
Abstract: Male strip connectors having plug contacts (2) are used for connecting the electrical wiring of apparatuses having conductor tracks on printed-circuit boards (12). The solder connector pins (5, 6) of these plug contacts are plugged into solder connecting cut-outs in the basic grid of the printed-circuit board, and are soldered to the conductor tracks on the rear side of this printed-circuit board. In order to prevent damage to the solder points during clipping on and removal of clip-on sleeves or by the contact tongue (3), the male connector strip is attached to the printed-circuit board, for example by means of screws (10). The attachment cut-outs (8, 9) are arranged at right angles to one another and between the plug contacts in a base body (1) of the male connector strip and not, as known until now, at the two ends of the male connector strip. In consequence, it is possible to arrange a plurality of identical male connector strips in a row, without any gaps, to form male connector strips having a greater number of plug contacts. Since the plug contacts have two solder connector pins (5, 6) which are arranged at right angles to one another and project at the solder connecting cut-out (13), the male connector strip can be plugged into a printed-circuit board in two different positions. One large clip-on sleeve or one or two small clip-on sleeves can be clipped onto the slotted contact tongue (3). <IMAGE>
