摘要:
Electrophotographic recording materials which comprise an electrically conductive base, charge carrier-producing compounds (sensitizers), and compounds which are charge carrier-transporting when exposed to light, possess high photoconductivity and low conductivity in the dark, and contain, as charge carrier-transporting compounds, 1,2,3-triazoles of the fomula ##STR1## are used for reprographic purposes and for the production of electrophotographic printing plates, in particular offset printing plates.

The present invention relates to a shingle-type building element in form of several shingle-like surfaces placed side by side forming a joint-structure or a single shingle piece, comprising a form of a plate which in the right angular cross-section shows the upper member with a width b a height h and a wedge-shaped lower member with the wedge point, with a truncated side, in case of a wedge stump which is later connected at the ridge, or the upper member facing the top of the wall by which the wedge-shaped lower member is either in the cross-section a triangle ABC of which side AC is equal to the height h of the upper member and of which the side BC is smaller than half of width b or the extension is such that it shows in the cross-section a triangle ABC, and a polygon joint below which gives after the building elements are laid in the cross-section a right angular basic member, by which the upper member and the lower member is one unit made of the same or different materials, the upper member of the single-type surface or joint structure show cuts in order to achieve the shingle-type effect this is not the case with the lower member.

摘要:
The present invention provides compounds of formula I, ##STR1## wherein R.sub.1 is hydrogen or alkyl of 1 to 4 carbon atoms in position 1 or 2 of the indazole nucleus,R.sub.2 is hydrogen, halogen, trifluoromethyl, hydroxy or alkyl, alkylthio or alkoxy of 1 to 4 carbon atoms, or a group of formula II, ##STR2## wherein X is oxygen or sulphur,R.sub.3 is hydrogen, halogen, trifluoromethyl, hydroxy or alkyl, alkylthio or alkoxy of 1 to 4 carbon atoms, andR.sub.4 is hydrogen or a group of formula II, as defined above, with the proviso that one of R.sub.2 and R.sub.4 is a group of formula II and the other is other than a group of formula II,useful as myotonolytics and anti-hypertensives.
摘要:
The present invention relates to indazole derivatives of formula ##STR1## wherein R.sub.1 is hydrogen or alkyl of 1 to 3 carbon atoms,R.sub.2 is hydrogen, halogen, hydroxy, or alkyl, alkoxy or alkylthio of 1 to 3 carbon atoms, andR.sub.3 is hydrogen, halogen, alkyl or alkoxy of 1 to 3 carbon atoms, or hydroxy, andA is dimethylene or trimethylene, wherein one hydrogen atom may be replaced by hydroxyl or alkyl of 1 to 3 carbon atomsUseful as anti hypertensive agents.
摘要:
A method and device are provided for allowing an efficient control of the establishment of connections of mobile radio phones that are present in an area hit by a disaster. According to the present invention, a sequence is transmitted in a single broadcast to all mobile stations in at least one cell of a mobile radio network present in the respective area. According to the sequence, a connection to a mobile station in the area is only established if the mobile station requesting establishment of the connection communicates the sequence when requesting establishment of the connection.

摘要:
The invention relates to a method for cleaning a particle filter (1) with the following method steps: a gaseous stream laden with pollutants and/or particles is fed to a particle filter (1) that operates catalytically and/or by filtration, pollutants and/or particles are chemically converted or stored in the particle filter (1), filtrate or ash particles (2) being produced and/or deposited on the particle filter (1). Once the particle filter (1) has been used for a specific period of time, a layer (3, 4) for increasing the through-flow resistance is applied to the layer of filtrate or ash particles (2) in the direction of filtration.
