PCT No. PCT/FI89/00011 Sec. 371 Date Sep. 11, 1990 Sec. 102(e) Date Sep. 11, 1990 PCT Filed Jan. 23, 1989 PCT Pub. No. WO89/07731 PCT Pub. Date Aug. 24, 1989.The invention relates to an apparatus for the formation of an insulating material ply, e.g. in the manufacture of insulating chutes. The object is to provide a continuous insulating material ply (17) of a predetermined thickness. A primary pl...

A packaging blank, which has a plane, mainly polygonal bottom zone (21) and has side-wall zones (22-24) which are connected to the bottom zone (21) by folding lines along the edges of the bottom zone (21), can be erected by means of an erection device. This device has a supporting surface (19), along the side edges of which are rotatably mounted rollers (14, 15, 17) which serve for bending or erec...

In order to achieve good stack water chemistry and minimize corrosion in a fuel cell stack [10] water cooling loop [12, 14], the oxygen concentration in the water must remain within a relatively narrow range. Stacks using steam separators [30] produce water in the separators which is relatively devoid of oxygen. Makeup water [38] is used to replace the steam lost from the separator, which makeup w...

A porous substrate of a fuel cell electrode assembly is formed by producing a fibrous carbon precursor web by means of a conventional wet papermaking process. The precursor web is then dried and saturated with a wet resinous binder which will carbonize when heated. Substantially the entirety of all of the carbon fibers in the web are thus coated with the binder, and substantially all of the inter-...

Novel polycyclic alkaloids of the formula in which R denotes hydrogen, acyl, sulphonyl, sulpho or phospho, and A denotes C=O or optionally acylated C-OH, where the dashed line symbolises a C = C double bond in the position of the central bond if A is C=O, or in the position of the two outer bonds if A is optionally acylated C-OH, a process for the preparation of these compounds by cyanidat...

The invention concerns a conduit connecting piece 1 for permanent or removable connection to the casing surface of an electrical installation box. In order that any stresses caused by the fixings do not cause these to break or cause the conduit connecting piece to loosen from these, that part 4 of the connecting piece 2 which faces the installation box is constructed of flexible material which ena...
