Patent DE-3026898-A1 (DE)
Title: Micro-capillary for one-off test - filled by capillary action with analytical reagents or control serums
Inventor: KEUL GUENTER
IPC: G01N33/52
Filed: 1980-07-16
Abstract: A microcapillary for a one-off test, for use in clinical laboratories for blood or urine checks, has been filled by capillary action with analytical reagents, biochemicals, control serums, standard or calibration substances or coated. A sample of blood or urine can thus be checked by direct reaction; based on a colour scale or comparative Table in qualitative, semiquantative or quantitative fashion. This saves the various pipette operations required in the conventional procedure of mixing a sample in turn with various reagents and to check the reaction in a dish. The tests are thus simplified and free from errors.

Title: 380V/220V adaptor
Inventor: HOPPE JUERGEN
IPC: H01R27/00
Filed: 1981-01-30
Abstract: The invention relates to an electrical installation device which makes it possible to take 220V AC from 380V three-phase sockets, by means of a German standard plug with a protective-earth contact. The adaptor is a combination of a front part with contact pins of a three-phase plug which fits the respective 16A/380V three-phase plug socket, inter alia PERILEX TM  system, CEE STANDARD etc. and a 16A/250V German standard socket with a protective-earth contact, connected to one another in a suitable manner in a housing. A plurality of adaptor variants are possible corresponding to the highly varied 380V system forms. The possibilities for use are for highly varied 220V electrical apparatuses to be supplied and operated safely from 380V three-phase sockets without having to replace the apparatus plug with a protective-earth contact for a corresponding 380V three-phase plug. This avoids considerable hazard sources in comparison with the present-day method (which is frequently practiced by laymen) of replacing the plug on 220V load apparatuses.

Title: Device for retinal photography
Inventor: KUEHM GERHARD
IPC: A61B3/14
Filed: 1981-07-31
Abstract: Device for retinal photography for the selective photographing of a flat image or a stereo image. The invention has the object of doing without the exchange of additional subassemblies on the standard unit, which has previously been necessary and which each time requires renewed adjustment of the device in relation to the patent, of achieving a higher image content than has hitherto been possible in flat images, of making better use of the light energy and of accomplishing the change-over from flat image to stereo image by simply switching over on the device. Starting from a first, second and third intermediate retinal image, the latter being formed in a stationary field stop and permitting optimum sharpness and a balance of the faulty vision of the patient's eye and selection of the magnification, optical subassemblies provided in the device are switched via mirrors both for the flat image and for the stereo image.

Title: Arrangement for keying-in an out-of-band signal frequency
Inventor: SCHOMERS JOSEF DIPL ING
IPC: H04J1/14
Filed: 1981-09-25
Abstract: The invention relates to an arrangement for keying an out-of-band signal frequency into the transmission path of a carrier-frequency channel converter with the aid of direct-current signals which are transmitted to the channel converter in the form of earth or non-earth and are there converted into an out-of-band signal frequency. The object of making such an arrangement monolithically integratable in a simple manner and with low losses was achieved by the fact that a capacitor (C) is charged by a switched current source (Is) via a time constant. The double-push-pull modulator, known per se and controlled by the charging and discharging voltage was modified to form a two-quadrant modulator by connecting the base terminals of three polarity-changing transistors. <IMAGE>
