Patent FR-2516434-A1 (FR)
IPC: B27M3/02
Filed: 1981-11-19
Abstract: 1. Device for splitting pieces of wood (9) in order to form laths by means of a blade (1) which is mounted on a support (2) and moved mechanically in a reciprocating manner, the said blade being also pivotable about an axis (3) which is adjacent to the cutting edge and substantially parallel to the latter, characterised in that the said blade (1), which is mounted pivotably on the support about the axis adjacent to and substantially parallel to its cutting edge, has an axis of articulation (3) which merges with the line of intersection between the plane of the flat surface (5) having the smaller width and that plane (15) of the blade face which is adjacent to this flat surface, in that the said blade has a substantially parallelepipedic rectangular flattenend form, its cutting edge being in the form of a dihedron situated along one of the long sides of the rectangle, in that the bisecting plane of the dihedron forming the cutting edge combines with the centre plane (7) to form such an angle that one of the flat surfaces (6) of the dihedron has a width distinctly greater than that of the other flat surface (5).

Patent FR-2514382-A1 (FR)
Inventor: SCHNAKENBURG JOACHIM
IPC: D21C9/10
Filed: 1982-01-26
Abstract: Chemically produced pulp is in the prior art bleached with chlorine in a reactor where the mixture of pulp suspension and of chlorine solution remains for up to 60 minutes. The remaining lignin is then extracted with sodium hydroxide solution; the relatively dark fibrous mass is bleached with hypochlorite or the like in a multi-hour process to produce a saleable half-stuff. This gives rise to chlorine-containing, organically polluted waste liquors containing a high BOD and difficult-to-biodegrade materials. The bleaching process of the invention comprises mixing chemically produced pulp with ozone while the pulp is at the same time subjected to a fibre individualisation (separation, fiberisation) process. This accelerates the rate of bleaching, even though only relatively small quantities of ozone are consumed. Especially the yield is increased and the COD of the overall bleach is appreciably reduced. The energy required for grinding also decreases significantly.

Patent FR-2537833-A1 (FR)
IPC: A01G13/00
Filed: 1982-12-20
Abstract: An apparatus is provided which promotes and enhances the development of microorganisms in the ground, which microorganisms are indispensible for promoting the growth of vegetation, including plants and trees, by recycling water and circulating air to the zone in which the roots of the vegetation are located. The apparatus includes a relatively severely flared, frustoconical skirt portion which is adapted to cap the roots of vegetation within the ground. It also incorporates a small, generally cylindrical collar which extends above the ground and which surrounds the trunk of the vegetation being protected. A plurality of drains, formed by channels along the interior surface of the skirt and collar, extend over the length of generatrices of the apparatus and serve to conduct water and air to the roots of the vegetation. The apparatus is formed by two identical members, each of which has a dimension greater than one-half of the collar and one-half of the skirt. These two portions overlap when attached and are connected by a flexible band or similar member. In addition to maintaining a fertile zone in which the roots of plants, trees and other vegetation can flourish, the apparatus protects plants from ingrowth of undesirable weeds and damage which occurs from the use of small agricultural tools.

Title: Defective fuel can detection by ultrasonics in rod cluster
Inventor: SCHARPENBERG RAINER
IPC: G21C17/06
Filed: 1983-12-14
Abstract: Defective fuel cans of rods within a complete cluster in a water-cooled reactor are identified by passing between the rods two probes (5, 6), one carrying an ultrasonic emitter and the other carrying a receiver.  Thus each rod in turn comes between emitter and receiver.  The transit time and the intensity of the ultrasonic signals passing (a) through a fuel can and (b) through the water between fuel cans are displayed on an oscillograph and evaluated. The probes (3, 6) are moved forward by steps and each time they stop the oscillograph picture is recorded.  The values obtd. are compared with a stored matrix of a fuel element cross-section. Pref. the distance travelled between two steps is 1/4-1/2 of the wall thickness of a can (2).
