Abstract: Chemically modified proteins obtainable by reacting casein, collagen, gelatin, albumin or mixtures thereof(a) with 0.5 to 15% by weight of chlorine or of a compound which liberates chlorine under the reaction conditions, in an aqueous medium at a pH of from 0 to 7 or(b) with 0.5 to 50% by weight of a non-aromatic mono- or disulfonic acid which contains in its organic radical one or more groups or structural features which react with nucleophiles, in an aqueous medium at a pH of from 6 to 14,are used as dispersants in colorant formulations.

Abstract: A microscope is disclosed having an illumination device that includes a color temperature regulating device and a color temperature measurement device. The color temperature regulating device includes a light guide and two conversion filters that are disposed on a carrier and are adjustable in a motor-driven manner. Moreover, a color temperature control device is provided, which compares the color temperature determined in the measurement device with a predetermined theoretical value and supplies a corresponding signal to the color temperature regulating device. Furthermore, a measurement or regulating device for the intensity of illumination or light intensity is provided, which compensates the change of light intensity by a motor-controllable diaphragm in the illumination beam path.

Abstract: Liquid phosphate-free single phase degreasing compositions for aluminum surfaces containing one or more builders, sequestrants and surfactants in aqueous alkaline solution, particularly containing alkali metal and/or ammonium carbonate, alkali metal and/or ammonium hydrogen carbonate, one or more acrylic polymers, optionally one or more other complexing agents which complement or partly replace the acrylic polymers, one or more anionic or nonionic surfactants, optionally other active substances and/or auxiliaries of the type normally used in degreasing compositions and water.

Abstract: A process for photographing microscopic objects with consideration of exposure time values to be determined and for making visible a spatially variable measurement spot and an exposure format making before and after the exposure is indicated, which process proceeds according to the process steps which are prescribed in accordance with the claims.

Abstract: Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.

Abstract: Processes for the introduction, visualization and/or recording of a variable detail metering field stop into part ray paths of a camera for optical instruments, for example microscopes, are described. In addition, appropriate devices are specified. They contain a reversibly illuminable multifield matrix (4), which is provided, at a fixed location, in a plane which is conjugated with the eyepiece intermediate image plane of the optical instrument.

Abstract: An attachment camera for microscopes, comprising an apparatus for measuring the brightness of an object detail and markings for sighting at least the detail metering field and the image field of the camera in the observation beam. The metering field markings and the image field markings are located on two separate plates, the plate with the metering field marking is defined by a measuring field stop. The two markings differ in size and shape and are simultaneously reflected into the observation beam by means of a photographic ocular located in the picture taking beam and by means of optical components with partly or fully reflecting surfaces located before or after the photographic ocular.A holder (5a) seating in exchangeable manner the photographic ocular (5) is provided between the housing (24) of the attachment-camera and the binocular tube (25).

Abstract: Photomicrographic exposure meter for cameras attached to microscopes in which part of the picture-taking beam is reflected by means of a beam-splitter and where the reflected beam part projects an image of the object onto an image plane, measuring field stop is located in the image plane with an aperture for detail or spot measurements and an insertable photo-electric detector cooperates therewith downstream of the stop in the direction of light.The beam part is reflected by at least one specular means (12,61) to the measuring field stop (13). The stop is gimbal-suspended and means are provided both for displacing the gimbal-suspended specular means (12,61) and for viewing the object detail appearing in the stop aperture.

Abstract: Disclosed is a light-metering system for an attachment camera of the type particularly adapted for use with an optical observation instrument having an optical axis comprising a mounting means positioned between the observation instrument and the shutter of the camera and being movable in at least two degrees of freedom; optical means positioned on the optical axis of the observation instrument for selectively deriving either an observation beam or a metering beam from the beam path of the observation instrument; a measuring diaphragm mounted on the mounting means and arranged in the image plane of the metering beam; a photoelectric receiver associated with the measuring diaphragm; a set of markings carried by the mounting means opposite to the measuring diaphragm and positioned in the observation beam; means positioned in the observation beam in a plane conjugated with the image plane of the observation instrument for viewing the image superimposed upon the set of markings; and means for moving the mounting

Abstract: Exposure measuring system for attachment cameras to microscopes provided with a focusing telescope which is provided with a transverse slot for the selective insertion of two sliders, one of which is provided at the approximate slider center with a photodetector for the exposure measuring system while the other consists of a transparent plate which bears a marking of circular shape or the like also approximately at the center of the slider and corresponding in size to that of the photodetector. The slot possibly serves only for the introduction of a single slider bearing both the photodetector and the marking a given distance apart and is correspondingly displaceable between two positions. The guide path (10) of the slider(s) (9) is displaceable in the plane of the slider and means (16) actuated from outside the focusing telescope are provided to cause slider displacement.

Abstract: Microscope-attachment camera with a system for measuring the brightness of an object detail and with markings for indicating at least the detail metering-field and the image-field of the camera in the observation beam. The metering field-marking (14) and the image field-marking (22) are positioned on two separate plates, the metering field-marking plate being designed as a metering field-stop (14), and the two markings which differ in shape and size (14,22) are simultaneously reflected into the observation beam.
