Patent EP-0018435-A1 (EP)
Inventor: STOCKER WINFRIED DR MED
IPC: G01N33/48
Filed: 1979-10-16
Abstract: An analysis system with which a random number of small to very small liquid specimens can be simultaneously examined side by side without hollow reaction vessels. The specimens do not mix together and do not dry out. To this end, the plates are provided with a water-repelling coating leaving free a number of circular surfaces. The individual specimens are placed between the coinciding circular surfaces of two superimposed plates. A frame ensures that there can be no reciprocal lateral sliding of the plates and that the latter do not move too close to one another. For mixing of the individual specimens, the plates can be rhythmically moved towards and away from one another within given intervals, e.g. by means of a spring-magnet system. The analysis system can be used in many immunological examinations, particularly blood group determinations, radioimmunoassays, enzyme-immunoassays, immunofluoroescent assays and in non-immunological, general chemical, biochemical and clinical chemical examinations.

Abstract: Character recognition apparatus detects baseline of a line of characters as an aid to segmentation in a recognition processor (16). The characters may include underlined characters, characters of different height, characters extending below the baseline, and characters with subscripts. A line of sensor elements of a scanner (11) makes vertical scans successively along a line of characters. The lowest character parts occurring in a narrow band or search window extending along the line of characters and including the baseline are determined by logic circuitry (26 to 29), and by a search window selection circuit (31), responsive to a coarse baseline prediction derived from character part histograms, each for a respective group of characters along the line. A histogram generator (13) develops the histograms. The search window technique excludes underlinings from baseline determination. Averaging circuits (32) determine baseline from the determined lowest character parts. Excessive coarse baseline skew prediction is recognised by the processor (16) and operation of the apparatus is halted to allow document repositioning.

Abstract: An apparatus for forming lather or soap foam for washing and/or shaving purposes comprises an actuation lever which simultaneously serves to drive a piston, a liquid soap-dosing pump and a membrane pump for generating compressed air. A perforated wall of a conduit or line enables blowing the compressed air into a dosed quantity of liquid soap located within a mixing chamber, to thereby form a coarse bubble lather or soap foam which subsequently is blown through a porous body, homogenized and compacted. Different embodiments of the apparatus can be realized and it is particularly suitable for use as a foot actuated structure and for producing hot lather for shaving. A preferred construction contains an intermittently operated heater for preheating the compressed air, to thereby accomplish a particularly effective generation of hot lather. The apparatus has the advantage of increased economy owing to its reduced consumption of liquid soap and can be faultlessly hygienically operated and is especially environmentally protective.

Abstract: The yarn pieces to be joined are stretched between the two pairs of suction tubes (28, 29; 30, 31) and untwisted by being wound about spindles (20, 21). Hot compressed air fed along the surface of two blocks (32, 33) adjacent to the untwisted yarn portions remove free fibers and distribute the fiber tufts in the base of a channel formed in said blocks (32, 33). Said tufts are retained in the base of the channel by an electrostatic field formed with the aid of conductors (46) and the generator (GE). The blocks are then rotated about the rotation shafts (4, 5) until the channel edges are in contact with each other. Air is fed perpendicularly to the plane containing the fiber tufts in proximity to their respective ends in order to cause the fibers of the two tufts to interpenetrate, the spindles (20, 21) then being driven in the reverse direction in order to twist the fiber tufts and to disengage the yarn.
