摘要:
The invention relates to a stratified material with a coating which is deposited on one side or both sides and which is comprised of a planar substrate containing acrylate. The synthetic resin is modified by means of high-temperature resistant, polymerizable nanoparticles having a glass transition temperature of the homopolymerizates ≧150 ° C. Said nanoparticles comprise a core consisting of silicon dioxide and of at least one side chain which is covalently bound to the core via one or several oxygen atoms of the oxide, and which is of the formula (MeO)x(Me—(CH2)n—(OCO)m—CR1═CH2)y, wherein Me represents Si or Al, x is 1 to 3, m is 0 and 1, n is 0 to 6, y is 1 to 3 and R represents H or CH3, whereby the free valences of Me represent a binding to another oxygen atom of the core or are saturated by alkoxy radicals.

摘要:
An apparatus for determining the position of a hollow section system which is pressed forward. Measuring apparatus are arranged one behind the other in the hollow section system. Measuring points are also provided. Each measuring apparatus has a light source for marking the position, a position detector, and an optical system. The measuring apparatus are arranged in such a way that the projection of the light source of each measuring apparatus takes place to the position detector of the respective adjacent measuring apparatus. The measuring apparatus are connected to each other for the transmission, and receiving, of signals present at the position detectors. The coordinates of the measuring apparatus can be determined from the signals, and from this the spatial position of the hollow section system can be determined.
摘要:
Spent reactor fuel elements are dissolved in dilute nitric acid. After addition of acetic acid as a complexing agent, the nitric acid is partly decomposed and the mixture subjected to electrolysis while a carrier liquid, which may be dilute acetic acid or a dilute mixture of acetic acid and nitric acid is caused to flow in the electric field between the electrodes either against the direction of ion migration or transversely thereto. The ions of uranium, plutonium and other transuranium elements, and of fission products accumulate in discrete portions of the electrolyte and are separately withdrawn as at least three fractions after one or more stages of electrolysis.
摘要:
An explosion-proof LED module has at least one light-emitting diode, a heat sink connected to this and an LED cover that covers the LED at least in the emission direction. The LED cover extends into an insertion recess of the heat sink. In this insertion recess, the LED cover is surrounded by a casting compound resulting in sealing of the LED relative to an outer and possibly explosive atmosphere. As a result, an explosion-proof LED module can be provided whereby the manufacture of said explosion-proof LED module is relatively simple and possible in an economic manner in a short time from prefabricated parts. At the same time, the explosion-proof module is furthermore characterized in that sufficient cooling corresponding to the ignition protection type “intrinsic safety” and an embedding of the component according to ignition protection type “encapsulation” are given.
摘要:
A lamp has a plurality of LEDs which are arranged behind one another in the lamp's longitudinal direction and in LED spacing by means of an LED carrier. Each LED emits light in a certain solid angle area around a beam center direction. The solid angle area is directed towards a lamp reflector for indirect light emission of the lamp. The number of LEDs and/or the LED spacing is selected in such a way that the solid angle areas of all LEDs after reflection at the light reflector overlap at least partially at an illumination surface distance from an underside of the lamp of at least 0.2 to 2.5 times the distance between the LEDs that are spaced the farthest apart from each other.
