Patent FR-2591403-A1 (FR)
Title: Method and device for converting a frequency by a small frequency shift
Inventor: BOUEDO ALAIN
IPC: H03B21/04
Filed: 1985-12-06
Abstract: According to the invention, in order to convert a frequency f0 by a small frequency shift fm, the following operations are undertaken: - translate a frequency qf0 by a shift q<n>fm (with q and n positive integers); - divide the frequency qf0 + q<n>fm thus obtained by the integer q; - translate a frequency (q-1) f0 by a shift equal to the frequency obtained following the previous division; - divide the frequency obtained following the previous conversion by the integer q; - repeat these latter two operations n-2 times, thus making it possible to obtain, at the end of the last operation, the desired frequency f0+fm. Applications: frequency synthesis.

Patent FR-2619860-A1 (FR)
IPC: F03C1/06
Filed: 1987-08-24
Abstract: The motor described comprises a casing (1) containing a stack of piston chambers (35) incorporated between a basic piston chamber (2) and a sealing block (3-5). The annular space between the casing and the piston chamber is divided into two semi-annular compartments one of which is under pressure the other being connected to atmosphere, by an upper window joint (6) one part of which has a reduced diameter to allow the passage of pressurized fluid, a lower window joint (7) and two small sealed lateral bars (8). Pressure is supplied to the individual pistons (51) through lateral openings. As the total surface under pressure is greater than in classic motors, a higher torque is obtained. The cylindrical design of the motor permits installation in confined spaces. As the piston chambers are rotated by the protruding extremity, the motor can be reversed as a pump.

Inventor: MERCIER MARC
IPC: C04B38/02
Filed: 1988-07-29
Abstract: The present invention relates to a process for the manufacture of activated alumina agglomerates and to the agglomerates obtained according to this process. It relates more particularly to a process consisting in forming an alumina body by agglomerating an alumina powder obtained by a fast dehydration of an aluminium hydroxide, characterised in that it consists: (i) in aging these alumina bodies in an atmosphere with a controlled degree of humidity, (ii) in impregnating the aged bodies with a solution of one or more acids (iii) in subjecting these impregnated bodies to a hydrothermal treatment in a confined atmosphere, and (iv) in drying and calcining these bodies. The process of the invention makes it possible to preserve the pore distribution during the aging and autoclaving stages. The agglomerates of the invention are useful especially as supports for a catalyst or adsorbent.
