Title: Drawn or self-propelled agricultural machine intended to form in situ an underground waterproof film
IPC: A01G25/00
Filed: 1986-01-30
Abstract: Drawn or self-propelled agricultural machine intended to form in situ an underground waterproof film. The invention relates to equipment intended to form an obstacle to the losses of rain water in sandy soil by forming in situ an underground waterproof film. This result is obtained by sending out under pressure a liquid or pasty product capable of hardening after extrusion into the sand by means of a die 10 of elongate shape. In order to reach this die 10, the product is firstly injected by the screw press 7 into the pipe 8 which directs it through a space 5 made in the coulter 3 to the back of the plough-share 4 where the extrusion die 10 is located. This method allows the cost-effective formation of buried waterproof pockets which can be used in soil-less cultivation, as well as artificial oases in those places where rainfall is sufficient.

Title: Method and device for physical analysis of the limpidity of packaged liquids
Inventor: EGEE MICHEL
IPC: G01N33/00
Filed: 1986-11-27
Abstract: The invention relates to a method and a device for physical analysis of the limpidity of packaged liquids B, A, T in a container. The packaged liquid B, A, T is rotated at omega R about a given axis of rotation DELTA , so as to allow migration of the inclusions or defects within the liquid. The container is illuminated using an electromagnetic radiation beam R with a radiation spectrum corresponding to a range of semi-transparency of the constituent material of the container and of the liquid. The radiation flux transmitted is recorded during the illumination, and the degree of limpidity of the liquid is determined by comparing at least one recorded value of the radiation flux transmitted with a reference value denoted (Vref). Application in the food industry, pharmaceutical industry and laboratory products field.

Title: Tree trunk debarking system
Inventor: LOEBNER ANDREAS
IPC: B27L1/05
Filed: 1987-07-08
Abstract: The debarking machine rotor (4) has a central hole through which the tree trunk is fed in its longitudinal direction.  The rotor carries a number of pivoted blades (11), which are so mounted that their cutting edges are pressed against the log surface by hydraulic cylinders (12).  The hydraulic pressure is maintained by a hydraulic accumulator (16). The pivot points of the blades are so arranged that the centrifugal force generated by the rotation of the rotor tends to swing the blades radially outwards.  The resultant pressure exerted by each blade on the trunk can thus be altered by changing the rotor speed.
