Title: Thermal transfer printing dyesheet and backcoat composition therefor
IPC: B41M5/26
Filed: 1988-10-13
Abstract: For a thermal transfer dyesheet, a protective backcoat is provided by polymerising acrylic functional groups in a composition comprising: an organic resin comprising at least one polyfunctional material having a plurality of pendant or terminal acrylic groups per molecule available for cross-linking, at least 10% by weight of the polyfunctional material having 4-8 such acrylic groups per molecule; at least one linear organic polymer soluble or partially soluble in the resin, and comprising 1-40% by weight of the resin/polymer mixture; a slip agent selected from derivatives of long chain carboxylic or phosphoric acids, long alkyl chain esters of phosphoric acid, and long alkyl chain acrylates; an antistatic agent soluble in the resin, and a solid particulate antiblocking agent less than 5  mu m in diameter. Resins having predominently 5-7 acrylic functional groups per molecule, are preferred for enhancing protection against the thermal head, especially when used in a mixture also containing molecules having only 2-4 such acrylic groups per molecule. The effect of using such mixtures to cross link molecules of both high and low acrylic functionalities in the presence of the linear polymers, is to enable good thermal protection to be provided by a durable low friction coating, which also cleans the thermal head during printing.

Abstract: Separation in solution of preselected ions from other 
ions of the same sign is effected with at least one membrane 
comprising (a) an ion transport selective film matrix formed 
from one or more hydrophobic, film-forming polymers comprsing 
covalently-attached ionizable radicals; and (b) a polymer 
effective to reduce the electrical resistance per micron 
thickness of film (a) by at least ℓ of an order of magnitude, and 
derived from units comprising monomers containing amino groups. 
A selective electrodialysis unit for effecting such separation 
comprises at least one thin, dense non-porous charged membrane 
defined as above, which has a dielectric constant and composition 
preselected to induce selective ion dissociation of a first group 
of charged ions upon the passage of current therethrough, so as 
to effect a substantial ion migration of the selected ion group 
across the membrane at a fraction larger than its relative 
concentration. The invention may be adapted for e.g. the 
selective transportation of nitrate ions from the diluting to the 
concentrating compartments of the unit, from an aqueous stream 
containing nitrate, bicarbonate and sulfate ions, the scale 
formation on the unit being thereby substantially reduced.

Abstract: Bei der selektiven nicht katalytischen Entstickung 
wird ein Rauchgasstrom in einer homogenen Gasphasenre­
aktion mit einem Reagenz, z.B. Ammoniak, in Kontakt 
gebracht. Es ist wichtig, daß die Kontaktzone sich ge­
nau mit der Zone deckt, in der das Rauchgas einen en­
gen, üblicherweise als "Temperaturfenster" bezeichne­
ten Bereich in der Nähe von 1000 °C durchläuft. Vor 
allem bei der Nachrüstung bestehender Feuerungen mit 
Entstickungseinrichtungen ist es oft schwierig, das 
Reagenz genau an der richtigen Stelle mit dem Rauchgas 
in Kontakt zu bringen.  
     Die Reagenzlösung wird in Form von Tropfen variabler 
Größe mit Trägergasstrahlen in den Rauchgasstrom ein­
geblasen. Die Tropfen werden in der Weise erzeugt, daß 
eine wäßrige Reagenzlösung an einer Kante mit einem 
Trägergasstrahl zusammengeführt wird. Bei großen Trop­
fen liegt die Stelle, an der die Verdampfung des Rea­
genz stattfindet, weiter stromabwärts als bei kleinen 
Tropfen. Daher läßt sich durch Änderung der Tropfen­
 
 
größe die Zone, in der das Reagenz in gasförmigem Zu­
stand mit dem Rauchgas gemischt wird, verschieben. Die 
Tropfengröße wird durch Änderung der Wegstrecke vari­
iert, die die Flüssigkeit in dem Trägergasstrahl zu­
rücklegt, bevor dieser aus der Düsenmündung austritt. 
Hierzu dient eine Düse (1) mit koaxialem, in Achsrich­
tung verschieblichem Innenrohr (12).

Title: Methods of generating waveforms
IPC: H04M1/50
Filed: 1989-06-15
Abstract: A method of generating pure and decaying sinusoidal 
waveforms is readily implemented on arithmetic 
processors found in telecommunications circuits. The 
method is based on finite-difference equations and 
provides a sequence of signals having a high degree of 
spectral accuracy compared with presently-used methods. 
The sequence of signals can be generated in real-time 
without templates (ROM-stored patterns) because the 
method requires only two multiplications (16,18) and one 
addition (12) for each signal value generated in the 
sequence. The method finds application in dual-tone, 
multi-frequency (DTMF) telephone dialing systems.

IPC: E03F1/00
Filed: 1990-06-12
Abstract: In a hollow construction at least partly embedded in the ground or surrounded by the ground for the transportation or storage of polluting substances, such as, for example, in a drain channel, it is proposed to embed the wall of the hollow construction (2) in a sealing layer (3) of a non-setting mixture of mineral sealing materials, in particular clay materials such as, for example, montmorillonite, with the addition of mineral substances. In order to obtain as tight a storage of this layer as possible with a high solids content and small pore volume, it is furthermore proposed to pre-mix in the dry state the materials forming the sealing layer and to insert them as a dry mixture; the moisture required for the effectiveness of the mixture as a sealing layer is supplied after insertion. By such embedding of the hollow construction, it is possible, for example in sewage systems, to prevent polluting seepage water from being transported both longitudinally and transversely into the surrounding ground even at any damaged locations possibly occurring, which seepage water escapes through these damaged locations. <IMAGE>
