Patent DE-4029487-A1 (DE)
Title: Coated paper drying - using blown air to form air cushion to carry web through dryers without contact
Inventor: KARLSTEDT BERTEL
IPC: D21H25/06
Filed: 1990-09-18
Abstract: The action to guide a paper web and its leader from a coating machine is applied by a number of contactless pneumatic carrier and dryer units. These deliver blown air at the leader, and across the whole web width, in the direction of web travel. The blowing force is less when the leader passes through than when it is applied over the whole width of the web. Where the web finally passes round a number of mesh cylinders, pneumatic air support is provided in the passage of the web between the cylinders. ADVANTAGE - The system forms an air cushion which supports and drives the web through the drying stages, without contact.

Title: Process for sampling contaminated ground water from bore-holes - using a pressure activated filter pipe integrated with the drill pipe at a known level
Inventor: GROTENDORST JOSEF
IPC: G01N33/24
Filed: 1991-10-11
Abstract: A process for obtaining water samples from bore holes is contaminated ground. The samples are identifiable as having come from a known (in depth) horizontal rock layer. After halting of the drilling ring at the required level, cleaning fluid is pumped down the hollow drill rod until it is clean. The drilling ring is then started again for a short period so that borings form a seal at a contraction around the drill rod (2), above the filter pipe (5). The cleaning fluid below the seal together with water from the surrounding strata is sucked into the inner channel (3) through the filter pipe (5). It is then sucked to the top in the normal manner for analysis. ADVANTAGE - The process is quicker and more reliable than previous methods and requires no additional mechanical equipment.

Title: Triazene and tri:aza-tri:methine dyestuff cpds. prodn. - by simultaneous diazotisation of diazo component and coupling with aryl or hetaryl amine in aq. medium under carbon di:oxide pressure
Inventor: RAUE RODERICH DR
IPC: C07D285/135
Filed: 1992-12-15
Abstract: Prodn. of triazene and triazatrimethine dyestuffs of the formula D-N=N-Z (I) comprises reacting an aromatic or heterocyclic diazo component of formula D-NH2 (II) with a (het)arylamine of formula H-Z1 in aq. medium in the presence of a HNO2 precursor (IV) and CO2 at 5-100 bar at 0-125 deg.C. D = the radical of an aromatic or heterocyclic diazo component; Z = arylamino or a heterocyclylimino gp. of the formula -N=Het; Het = a heterocyclic diradical; Z2 = (het)arylamino. USE/ADVANTAGE - Diazotisation and coupling take place simultaneously if the CO2 pressure is over 5 bar. Diazotisation in mineral acid soln. and coupling in the presence of acid-binding agent leads to the formation of inorganic salts, which pollute the waste liquor and must be removed by costly methods, e.g. pressure permeation or reverse osmosis, to produce stable (I) solns. The new process avoids these drawbacks and is economical and environmentally friendly. Cationic (quaternised) (I) are useful for dyeing e.g. polyacrylonitrile.
