摘要:
The invention contemplates a process for the crystalline precipitation of a chromogen from solution thereof in a solvent and within a capillary. The process involves first initiating a course of crystalline precipitation of the chromogen by initially and locally supersaturating the solution within the capillary, and thereafter evaporating the solvent at a rate and in an environment sufficient for further crystallization to proceed unimpeded by local supersaturation.

The present invention relates to an electronic proximity sensor having a decorative surface, characterized in that the decorative surface comprises a semiconductor layer, the thickness of which is between 10 nm and 100 nm. This coating imparts a desired metallic appearance to the proximity sensor, without the property thereof as a proximity sensor being lost.

The invention relates to a method for producing an insulating glass pane comprising a plastic spacer, wherein two glass panels (25, 49) arranged parallel to each other have a target distance from each other, by □forming a composite strand (26) by the temporal and spatial overlapping extrusion of at least two plastic partial strands (23, 24), wherein a first partial strand (23) is made of an adhesive first sealing compound (3), in which a moisture-binding substance is embedded, and a second partial strand (24) made of an adhesive and binding second sealing compound (4), a first glass panel (25) along the edge of the glass panel (25), specifically such that the beginning and end of the composite strand (26) abut and form a frame in that the first partial strand (23) is extruded with a predetermined first target thickness, which is greater than the target distance, and the second partial strand (24) is extruded with a predetermined second target thickness, which is greater than the target distance, on the glass panel (25), the partial strands (23, 24) are located next to each other in the composite strand (26) and thus immediately adjoin each other, and the first partial strand (23) is located within the frame formed by the second partial strand (24), □joining the first glass panel (25) to the second glass panel (49) such that the composite strand (26) is located between both glass panels (25, 49), connects them to each other, and keeps them at a distance from each other and □setting the target distance by pressing the joined glass panels (25, 49).
摘要:
A method for assembling insulating glass panes from two or more glass sheets filled with a gas other than air, two plates facing each other, arranged parallel to each other vertically or inclined with adjustable mutual distance, a horizontal conveyor arranged near the lower edge of the plates, a first sealing device and a second sealing device, positioned at the protruding edges of both the plates or near these edges or between the plates and can extend between the horizontal conveyor and a point lying above the horizontal conveyor, and having means for feeding a gas other than air into a chamber, delimited on both the sides by the two plates and by the two sealing devices. For assembling overlong insulating glass panes, the glass sheets, at one of which a frame-like spacer is attached on both the sides, are positioned between the plates opposite each other.

摘要:
Enzyme substrates in aqueous liquids are continuously measured by introducing a sample containing the substrate to be determined into a current of buffer solution, reacting the substrate on an immobilized enzyme and measuring, in a measurement chamber, a physical change in the solution brought about by the reaction, wherein a current of buffer solution containing the sample to be determined is passed alternatingly (i) directly through the measurement chamber with the production of a reference signal and (ii) first over the immobilized enzyme and thereafter through the measurement chamber with the production of a measurement signal, and relating the reference signal to the measurement signal to indicate the enzyme substrate initially present.
摘要:
A method and device for preparing a paste-like compound having at least two constituents which set after having been mixed. The mixed compound is injected into an intermediate space between two glass panels of an insulating glass pane by delivering the at least two constituents from storage containers into separate intermediate storage units from which they are delivered into a mixer in which the constituents are mixed while passing through the mixer. The compound leaving the mixer is injected into the intermediate space between the two glass panels by a nozzle which has at least one opening directed into the intermediate space between the glass panels. The nozzle is moved along the edge of at least one of the two glass panels. The constituents of the paste-like compound are pumped using gear pumps from the intermediate storage units into the mixer, where they are dynamically mixed by motor-driven mixing elements.
摘要:
A sealed insulating glass unit comprises two glass sheets held apart by a spacer, optionally with a sealant between the edges of the glass sheets outside the spacer. The insulating glass unit contains an electronic device, having information relating to the origin, manufacture and/or properties of the insulating glass unit capable of being read from the device by means actuated from outside the insulating glass unit. The device is embedded within the spacer or sealant so that it is concealed within the insulating glass unit.

The invention relates to a radar-transparent component comprising a plastic body. Said component is characterized in that at least parts of the surface have a coating with a thickness of between 10 nm and 100 nm that comprises a semiconductor. Said coating gives the plastic body the desired metallic appearance without the body losing the characteristic of a radar-transparent component.
