Patent FI-921930-A (FI)
Inventor: LEBLANC PETER
IPC: B04C3/00
Filed: 1992-04-29
Abstract: A screening apparatus comprises a pair of stationary concentric screens with a plurality of foils rotating therebetween and adjacent thereto, the individual foils being radially aligned. The screening apparatus comprises a tangentially disposed slurry inlet and a diametrically and tangentially disposed heavy rejects outlet at the end of a heavy rejects trap. The light reject/accepts slurry flows into the screening zone and, after separation, is discharged at an end of the screening apparatus by way of respective light rejects and accepts outlets. The accept outlet is located axially with respect to the screen cylinders and rotating foils so the pressure pulses are virtually eliminated in the screening process. The apparatus may be constructed for vertical or horizontal rotation of the foils.

Abstract: The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. The prongs may also have an azimuthal angle relative to the machine direction of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of extruding liquid material through the meshes of a deposting member onto a moving substrate to form the base of the prong, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent article specifically a diaper, is also disclosed.

Abstract: The invention concerns a hydroxypropyl starch ester (HPS ester), compositions containing it, and a process for the preparation thereof. According to the invention, the molar substitution in the HPS ester is 2 at the most and the substitution degree in the ester group is at least 1. The HPS ester is prepared by hydroxypropylating a starch-containing base material in an aqueous alkanol medium. A starch component can be prepared of the HPS ester containing 90 to 60% by weight HPS ester and 10 to 40% by weight of a plasticizer. Compositions which are suited for, e.g., coating board or paper and for use as a component in labelling adhesives or paint, can be made from the starch component by combining it with auxiliaries known as such within the polymer and plastics technology.

Abstract: 644,900. Helicopter rotor blades. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and SHAPIRO, J. S. Jan. 15, 1948, No. 1258. [Class 4] A rotor blade for a helicopter or like rotary winged aircraft comprises a tubular or solid main spar shaped to conform to the leading part of the aerofoil section and a thin-walled trailing portion supported by the main spar, the continuity of the material of the spar normal to the principal neutral axis of the section being partially interrupted on or near the said axis in the neighbourhood of the leading edge, thus displacing the flexural centre of the blade section toward the trailing edge. The flexural centre may thus be made to coincide with the centre of gravity and centre of pressure of the section without materially lowering the tensile and flexural strength and stiffness of the blade. As shown in Fig. 6, the main spar is a metal tube 10 the wall of which is folded inwardly at 17a to form a discontinuity at 17 across the principal neutral axis, which is the chord line joining the leading and trailing edges. The structure comprises also a channel sectioned member 18 riveted at 19 to the spar 10, chordwise plate ribs 21 lightened by holes 23 and a skin 11 riveted at 20 to the member 18. In Figs. 3 and 4 (not shown), the spar 10 is formed either of seamless tube with a milled notch at the leading edge or of tube with a welded seam along the leading edge, the weld only extending partially across the seam. Fig. 9 shows a blade constructed of wood, plastic or like material, the main spar 10d comprising blocks 33, 34 glued or cemented together along a joint 35, lying substantially at the principal neutral axis, the joint being left open between the points 37. The blocks 33 and 34 are formed with a hollow 36 and glued to a plywood skin 24. In another construction (Fig. 8, not shown), in which laminated " improved " wood or like material is utilized for a solid spar the discontinuity is at the rear portion of the spar ; an arrangement made possible by a thick plywood skin which furnishes a large part of the strength of the section. In a further construction (Fig. 7, not shown), the spar comprises a pair of nested tubes the inner one being notched at the leading edge.
