Abstract: A forming fabric for making an endless belt for a papermaking machine is produced by first weaving a length of conventional fabricwith warp yarns (10) extending from each of its two ends. A selected number of the extended warps (10) are then cut at each end so that each cut warp (10a) is adjacent a remaining extending warp, and loops (14, 14') are formed from the remaining extending warps at the ends of the fabric. The ends of the looped warps are woven back through fills (12) of the fabric to a position near the cut warps (10a) and to provide tail ends (20) of the looped warps projecting from the surface of thefabric. Thefabric is made into an endless belt by joining its two ends, and this is done by interleaving the loops (14, 14') of the two ends (A,B) inserting a joining pin (18) through the interleaved loops (14,14'), and pulling the projecting tail ends (20) of the looped warps to tighten the loops around the joining pin and draw the ends of the fabric together.

Abstract: Apparatus for conveying and handling delicate articles such as fish includes an elongated inlet duct adapted to extend into an article storage region, such as the hold of a ship. The suction producing means (40) provides for a flow of air through the elongated inlet duct at a velocity sufficient to entrain the articles in the air flow and to carry same through the inlet duct. A separating means is interposed between the suction producing means (40) and the inlet duct for receiving articles passing through the inlet duct and for separating such articles from the air flow. The separating means includes a hollow chamber (32) of generally circular cross-section defining a generally upright axis of symmetry, such chamber (32) having an air inlet channel (58) connected to the inlet duct and an air outlet channel (52) connected to the suction producing means (40) whereby the latter maintains a sub-atmospheric pressure in the chamber (32). Inlet channel (58) and outlet channel (52) are generally tangentially disposed with respect to the circumference of the chamber (32) so that air entering the chamber (32) via the inlet channel (58) moves in a rotational pattern around the chamber axis and thence outwardly of the outlet channel (52) without reversing its direction of rotation. Articles entrained in the entering flow are guided around the chamber axis by the interior wall of the chamber (32) and move downwardly within the chamber (32) in a spiral path under the influence of gravitational forces thereon.

Abstract: Une electrode de diffusion de gaz (8) est utilisee dans une cellule electrochimique (9). L'electrode est du type pourvu d'un catalyseur exterieur pour convertir du gaz en electricite et contenant interieurement un materiau hydrophobe. L'electrode est caracterisee par le fait que le materiau hydrophobe comprend une couche plastique cohesive poreuse, qui definit un espace gazeux ferme dans l'electrode'ou l'electrolyte ne peut entrer, bien que l'electrode soit immergee dans ce dernier. D'autre part, du gaz peut etre aspire dans cet espace et peut en sortir. Lorsque l'electrode (8) est partiellement immergee dans l'electrolyte (12), du gaz est automatiquement aspire depuis l'atmosphere (13) au-dessus du niveau de l'electrolyte de la cellule et dans l'espace gazeux, a cause de la basse pression regnant dans l'espace pendant l'operation. En raison de la bonne capacite de l'electrode, il a ete possible de fabriquer cette cellule entierement fermee par rapport a l'atmosphere environnante, ce qui permet une construction tres simplifiee depourvue de conduite de gaz connectee a la cellule. La cellule est specialement utilisable comme pile metal/oxygene, cellule a combustible et pile oxyde metallique/hydrogene.
