The invention concerns crosslinking of isotactic polypropylene considered until now as a non-crosslinkable polymer. Polypropylene crosslinking not only generates novel uses but also the prospects of mixing and recovering operations both economical and ecological, with other polymers. Crosslinking or interpenetrating polymer networks (IPN) (as is the case with polypropylene/polyethylene mixture) provides both interesting properties and significant economic and ecological interest. The principle of the crosslinking mechanism is to create macro radicals and cause them to act immediately on sulphur before the reaction of the peroxide termination. The mixing process used is extrusion but other processes of transformation used for thermoplastics would be useful for subsequent industrial exploitation.

The invention concerns an electrically powered concrete pump for preparing and injecting concrete obtained by the technique of the inventive machine. The concrete pump mainly consists of a mixing drum (1) for mixing the materials, an electric motor (27) powering the assembly of mechanical elements and an air compressor and an assembly of accessories for optimising to a maximum the operating conditions and the performance. The mixing drum (1) is internally equipped with a replaceable curved wearing plate. The mixing drum (1) is equipped with a closure cover (46) resistant to the high pressure exerted by the air compressor during concrete transfer operations. On the mixing drum (1) are mounted two skips (34) or (hoppers) feeding the mixing drum (1) with building materials. It is shaped like a mobile visor and is synchronised with the movements of the machine.

characterised by using wave or tide energy
The invention relates to a wave-driven generator that is an electricity generator operating by means of energy contained in the movement of waves in the sea. The operating principle of said wave energy converter is a giant pulley (10) with monodirectional rotation (one-way). In order to capture the movement of the waves, a rack (2) (bar toothed on both sides) is fixed to a buoy (1) (to a float) that moves up and down. This drives a gear for converting said back-and-forth motion into a rotating movement. This causes the movement of the giant pulley (10). If it is applied in the field of mechanics, the invention will enable the improvement, for example, of the operation of a ratchet wrench by eliminating the empty return.

The invention concerns a system based on six essential elements: 1) water tank; 2) pumping and surge station; 3) pipe systems; 4) mechanical injectors or injectors equipped with microprocessors; 5) pressure regulators; 6) valves and fittings. The assembly of said elements enable an amount of water (15) to be supplied at a specific pressure. Concerning the novel element: the injector, it enables reduction of the average flow rate of a hydraulic point of a diameter of 14 millimeters at a pressure of 12.78 m3/h to 1.02 m3/h as well as the control of said liquid so as to deliver to one or several consumers the same amount of water at the same pressure simultaneously.

Boron; Compounds thereof
The invention concerns a product consisting of several natural elements whereof some attract insects and stimulate their appetite and whereof one among them, slightly toxic, poisons them very gradually. The invention is characterised in that the boric acid dose is such that its action is cumulative at the level of the digestive tract. Said slow and gradual action is the main reason for the absence of the development of antibodies by the insect. Since boric acid is a mineral substance which does not deteriorate in time, its action is permanent owing to its consisting of natural elements; the inventive product is harmless for humans and does not affect the environment. So as to avoid the decomposition of the natural elements, a fungicidal product may be added to the finished product.

The invention concerns a double-rod shock absorber provided with two chambers, a compression chamber (1) and an expansion chamber (2); two rods, a compression rod and an expansion rod; two pistons, a compression piston (3) and an expansion piston (9), and two coil springs, a compression spring and an expansion spring (13). The compression piston is comfortably compressed as a result of the wide surface of comfort orifices, and returns to neutral position with control provided by the control valves (5) (in the first system) or by the control groove (11) (in the second system). The expansion piston extends comfortably as a result of the wide surface of comfort orifices, and returns to neutral position with control provided by the control valves (in the first system) or by the control groove (in the second system). Said shock-absorber solves the problem resulting from the relationship between speed and force.

The invention concerns a sterilising pill for definitively stopping female reproductive capability without resorting to surgery through the traumatic experience of tubal ligation and which can be used as a contraceptive method. Said pill consists of a freeze-dried human ovum associated with folliculin and a carrier, the whole assembly is protected by a fine film. Said method consists in taking one single pill on an empty stomach followed by contraception during three successive months by any contraceptive method. The expected result is achieved only as from the third month. Said contraceptive and sterilising method is irreversible owing to the presence of antibodies directed against the ovum. The sterilising pill is designed for women who for some reason or another wish to be sterilised, that is suppress their reproductive capability.
