Abstract: TITLE OF THE INVENTION            GAS GENERATOR FOR INFLATING AN INFLATABLE ARTICLE            ABSTRACT OF THE DISCLOSURE            A gas generator for inflating an inflatable article such as a safety bag or raft, has a reaction chamber (1) sur-rounded by a ring-shaped filter chamber (2).  First gas exit openings (10 to 15) permit generated gas to flow from the reaction chamber into the filter chamber.  Second gas exit openings (22) lead from the filter chamber into the inflatable article.  A temperature responsive flow control is provided to make sure that the inflation efficiency or the inflation pressure inside the inflated article is sub-stantially constant and substantially independent of the temperature of the gas generator at which the ignition of a gas generating fuel begins.  For this purpose the total cross-sectional flow area of the first gas exit openings and/or the average gas flow path length between the first and second gas exit openings is controlled so that with a rising temperature the flow cross-sectional area and/or aver-age path length is increased while the area and/or path length is decreased in response to a decreasing temperature.

Title: A process for transfer pattern printing of a moist textile web, and a system as well as a pattern carrier web for use in the process
Inventor: AKERBLOM INGA S
IPC: D06Q1/12
Filed: 1990-03-16
Abstract: A  process  for  transfer  pattern  printing  of  a  moist textile web, and a system and a pattern carrier web for use in the process A b s t r a c t In a process for transfer pattern printing of a moist textile  web  consisting  wholly  or  predominantly  of natural fibres, in particular cotton, and/or artificial fibres on the basis of cellulose,  the pattern carrier web is a web of paper or a paper-like material which carries a pre-printed pattern of a water  soluble or dispersable dye. After wetting of the textile web to a carefully controlled moisture, the textile web is joined with the pattern carrier web and the joined webs are compressed at a suitable pressure so that the pattern can be transferred without using heat.            The advantage is that it will be possible to avoid both heating and use of organic solvents. It is also possible to transfer a pattern to a coloured textile web since the textile web may be wetted beforehand with an aqueous dye solution or dispersion instead of undyed liquid.
