Title: Numerical multiplier connected to integrator - variable figure added to truncated representation of multiplier to communicate to its desired average value
Inventor: COMTE MICHEL LE
IPC: G06F7/52
Filed: 1974-06-28
Abstract: A calculation system uses a numerical multiplier having M inputs for multiplier figures and N inputs for multiplicand figures, for a series of multiplications between a multiplier and a multiplicand. The multiplier has constant amplitude, and is formed from a number of figures greater than M. The amplitude of the multiplicand is evolved from one multiplication to another and is formed of N figures. The results of the multiplications are transmitted to an integrator. A variable figure is added, from one multiplication to another, so as to communicate to it a desired average value, designed to diminish errors due to the fact that a certain number of low weight figures of the exact representation of the multiplier must be neglected.

Title: Automatic pellet implanting device - for subcutaneous introduction of prods into animals
IPC: A61D7/00
Filed: 1974-10-15
Abstract: Automatic pellet implanting device is intended for the subcutaneous introduction of pre-determined doses of prods., which may be medicaments, for the care or treatment of animals. The device comprises a hollow needle, a charger communicating by the pellet arrival tube with an interchangeable magazine contg. the pellets, a housing adjoining the charger, an ejector sliding in the charger, the hollow needle and the housing, and means for controlling the movement of the ejector in the housing. The point of the hollow needle is forced under the skin of the animal to be treated; this is followed by the expulsion of the pellets from the charger and their propulsion through the needle. once the first of the pellets has taken up its posn. at the end of the needle, the latter is withdrawn slowly while the pellets pushed forward by the ejector take the place of the needle in the tissue of the animal, in proportion as the needle is withdrawn. Both manipulation and maintenance are simple; the charger is easily filled with the desired dose and the risks of jamming and crushing of the pellets are eliminated.
