Abstract: A method is provided for delignifying and bleaching a lignocellulose material, wherein an aqueous solution of a redox catalyst and an oxidant is reacted with the material. The catalyst comprises an organometallic cation of the general formula [(1)Mno.sub.2 Mn(L)].sup.n+, wherein Mn is manganese (III) or (IV) oxide, the two Mn's of this cation may form a pair in a III-III, III-IV or IV-IV oxidative state, n is 2, 3 or 4, O is oxygen, and L is a ligand comprising 4 nitrogen atoms co-ordinating the manganese.

Abstract: This device includes a support (14) provided with a semicylindrical seat (15) intended to receive a connection piece segment (12). This segment (12) has a semicircular collar (170) inclined with respect to the axis of the connection piece and intended to penetrate into a groove (16) having the same inclination as the collar (17) with respect to the axis of the semicylindrical seat 15. As a result, when a traction force is exerted by the pump on the portion of the connection piece, and the collar (17) engages the groove (16), this force tends to press the segment (12) against the seat (15) and cause self-locking of the assembly.

Abstract: For an endoscopic resection or examination of a body cavity or joint where a physiological liquid is pumped at one location to a joint from a feed conduit connected to a feed pump and withdrawn at another location from the joint through a suction conduit connected to a suction pump, this suction pump is operated at a rate corresponding to a generally constant low rate of flow in the suction conduit and the feed pump is operated in accordance with the pressure detected in the joint to maintain the pressure above a predetermined desired level. Furthermore when a tool carrying one end of an auxiliary suction conduit is inserted into the joint so that periodically this conduit can be connected to the pump so that liquid can be withdrawn from the joint through this auxiliary conduit, the method comprises the step of automatically increasing the suction-pump rate when the auxiliary conduit is connected to the suction pump to a predetermined relatively high rate.

Abstract: The thermoformable element comprises a strip (1) formed from two layers of foam (2, 3) of a thermoplastic polymer. The layers are welded to one another along their longitudinal edges so as to form a space between them in the shape of a channel (4). The inlet for the channel can be controlled by a non-return valve (6) whereas the exit can comprise a plug (7). The element is thermoformed by circulating a fluid heated to 130.degree. to 140.degree. C. through the channel until the foam becomes soft.

Abstract: A method and apparatus for making filaments and a fibrous product of randomly overlying filaments in a mat configuration bonded to each other at areas of intersection. The filaments are formed by subjecting a travelling layer of a settable, dielectric, molten polymer material to an electrostatic field of lines of flux of sufficient density and intensity to flow from the layer of molten polymer a multiplicity of filaments which are partially set as they form. The filaments are subjected to the field along enough to separate them from the surface of the layer and are then collected randomly overlying each other in a tacky condition so that they bond to each other in areas of intersection. The method may include insertion of an object in the path of the separated filaments for collecting them on a surface of the object. The object can be rotated so that a package of the matter material is formed about it to protect it.

Abstract: A metal wire to be coated with thermoplastic material is advanced at high speed, e.g. of 100 meters per minute, through a codirectionally moving mass of thermoplastic particles after having been heated to a temperature high enough to cause adhesion of these particles to the wire. The mass is mechanically entrained in a treatment chamber by an endless belt or the like at a speed close enough to that of the wire to hold the velocity difference therebetween below a threshold value, such as 30 meters per minute, above which an abrasive effect sets in which tends to detach already adhering particles from the wire. Upon exiting from the treatment chamber, the wire is reheated to fuse these particles into a continuous envelope and is then subjected to an electrostatic flocking operation for studding the envelope with radially projecting cellulosic fibers forming a velvety coating thereon.

Abstract: A cable for telephone or other communication circuits comprises a number of conductor arrays, specifically pairs or quads of helically intertwined conductors, each conductor having a metal core coated with a thermoplastic sheath in which a multiplicity of short cellulose fibers are embedded; the fibers have an average length of about 1 mm and project generally radially from the sheath over the greater part of their length. The fibers of the twisted wires interpenetrate and form a mat in the intervening spaces which swells in the event of water penetration through a defective envelope, thereby limiting the propagation of moisture along the cable.
