Patent EP-0206682-A3 (EP)
IPC: F02K7/08
Filed: 1986-06-13
Abstract: A method is disclosed of transferring energy into a flow of 
air without use of rotating parts, in which an inlet flow of air is 
made to swirl into a first circular path moving longitudinally of 
a housing, heat is added to the inlet flow of air at the end of the 
first path to produce hot gases, and the hot gases are directed 
into a second swirling circular path coaxially of and within the 
first path and having an open interface therewith, whereby 
energy is transferred from the hot gases in the second path into 
the inlet flow of air in the first path. An embodiment of the 
method is disclosed in the form of a fluid mass reaction engine 
having an annular housing (11) including an inlet (10) thereinto 
and an outlet (38) therefrom, a combustion chamber (25) in the 
housing spaced from the inlet, spaced coaxial openings into 
and out of the combustion chamber, and a means for heating 
air flowing through said combustion chamber. A first swirling 
device (14) acts on air entering the inlet to produce a circular 
flow of air moving into the combustion chamber and having 
a substantial component of centrifugal velocity, a second 
swirling means (30) acts on hot gases flowing out of the 
combustion chamber to produce a swirling flow of hot gases 
within the incoming circular flow of air moving toward said 
housing inlet and having also a substantial component of 
centrifugal velocity. A means (32) for directing the hot gases 
leaving the interface to the housing outlet, and a means (35) 
upstream of the housing outlet for changing the swirling flow 
of hot gases into an essentially linear flow, provide a motive 
reaction jet passing through the housing outlet.

IPC: G06F7/48
Filed: 1988-06-07
Abstract: Bei technisch-wissenschaftlichen Berechnungen mit Gleit­
punktzahlen auf Computern kann es durch Akkumulation von 
Rundungsfehlern zu Verfälschungen der Resultate kommen. 
Durch Umwandlung der Gleitpunktzahlen in Festpunktzahlen 
und anschließende Ausführung der arithmetischen Operationen 
im Festpunktformat können diese Rundungsfehler vermieden 
werden. Das Rechenwerk in der Rechenanlage verarbeitet dann 
die Festpunktzahlen. Dazu ist erforderlich, daß die Fest­
punktzahlen in den Registern, auf die das Rechenwerk zu­
greift, lagerichtig angeordnet sind. Bei einem umfangrei­
chen Gleitpunktformat führt dies zu einem entsprechend 
großen Festpunktformat und damit zu einem entsprechend 
großen Register. Um bei einer Rechenanlage, die derartige 
Gleitpunktzahlen verarbeitet, einen Multiuserbetrieb oder 
einen Multitaskbetrieb zu ermöglichen, ist ein Speicher (SP) 
vorgesehen, der in Abschnitte (AB) gleicher Länge aufge­
teilt ist. Jeder Abschnitt (AB) ist weiterhin in Segmente 
(SG) gleicher Länge unterteilt. Jeder Abschitt hat eine 
solche Länge, daß eine Festpunktzahl im Langformat gespei­
chert werden kann. Zusätzlich können in einem Segment (SG0) 
des Abschnittes Verwaltungsdaten gespeichert werden, die an­
geben, in welchem Bereich der Festpunktzahl im Langformat 
die zu verarbeitenden Daten enthalten sind. In den Segmenten 
der Abschnitte können weiterhin Gleitpunktzahlen gespei­
chert werden. Die Zuweisung der Abschnitte zu Festpunkt­
zahlen und Gleitpunktzahlen ist variabel und kann den ein­
zelnen auszuführenden Aufgaben angepaßt werden. Das Rechen­
werk der Rechenanlage kann mit den verschiedenen Abschnitten 
des Speicher zusamenarbeiten, wodurch ein Multiuserbetrieb 
oder Multitaskbetrieb möglich ist. Jedes der Abschnitte des 
Speichers kann somit in der Funktion eines Akkumulators 
verwendet werden.

Title: Graft polymers with a polyurethane backbone, their preparation process and use
IPC: C08F283/00
Filed: 1988-09-17
Abstract: Graft polymers in which vinyl carboxylates and optionally further ethylenically unsaturated monomers are grafted polymerically onto polyurethane backbones by free-radical-initiated graft polymerisation, and products of the hydrolysis of the graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and optionally further ethylenically unsaturated, polymerisable and optionally copolymerisable monomers in amounts of from 10 to 99% by weight, based on the graft polymer, onto a polyurethane backbone containing at least 2 urethane groups in the molecule, and, if desired, subsequently partially or fully hydrolysing and/or alcoholising the vinyl ester units and any further hydrolysable monomer units in the grafted-on polymer radicals of the graft polymers. Vinyl esters which are preferred for grafting are vinyl acetate and/or vinyl propionate and possibly vinyl versatate. The graft polymerisation is carried out in solution or in bulk and can also be carried out in emulsion or suspension. Unhydrolysed graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives. Fully and partially hydrolysed graft polymers are suitable, inter alia, for the production of films. Depending on the polyurethane backbone, the degree of grafting, the degree of hydrolysis and the type of grafted monomers, the graft polymers, compared with polyvinyl alcohol, can have significantly lower melting points, and are thus advantageously suitable for the production of pressed or extruded films under mild temperature conditions without the additional use of organic plasticisers. Hydrolysed graft polymers are furthermore suitable, inter alia, as adhesives.

positive photo-resist layer (16,18) is preferably 
applied to the partially decomposed layer (14) and 
selectively irradiated to define a mask (18) overlying 
the selected region. Unwanted photo-resist material is 
dissolved from the adjacent regions using an aqueous 
alkaline solution. It is found that the solution 
concurrently dissolves the underlying partially 
decomposed tin compound, without dissolving the tin 
compound protected by the mask (18). Thereafter, the 
mask (18) is removed, and the underlying tin compound 
is heated and further decomposed to produce the desired 
tin oxide thin film (22).
