IPC: C07C1/00
Filed: 1974-01-16
Abstract: Catalyst for carrying out heterogeneous catalytic chemical reactions. The catalyst is a composite comprising a solid carrier and at least one member of the group of carboxymethane sulfonic acid and products resulting from the thermal treatment thereof at a temperature not exceeding 350 DEG C. The catalyst is prepared by impregnating the carrier carboxymethane sulfonic acid or a precursor or precursors thereof, drying the impregnated carrier at a temperature not exceeding 170 DEG C and baking the so dried product at 170 DEG  to 330 DEG . Examples of catalytic reactions that are successfully carried out with such a catalyst are production of alcohols by hydration of olefins, production of esters from acids and olefins, production of esters from alcohols and alkylation of aromatic hydrocarbons.

Title: Anti brucellosis vaccine - consisting of the covering or walls of brucella cells free from their cytoplasmic contents
Inventor: DUBRAY GERARD
IPC: A61K39/10
Filed: 1974-10-11
Abstract: Antibrucellic vaccine consists of the covering or walls of Brucella bacterial cells, substantially free from their cytoplasmic contents. The vaccine is used to prevent brucellosis in man and animals and has the advantage of being very effective whilst enabling a distinction to be made between vaccinated animals and animals infected with Brucella, in the standard test. Cultures of Brucella, which may be of any strains of B. abortus, B. melitensis, B. suis or B. ovis, are treated mechanically to rupture the cell walls, and then treated enzymatically to eliminate the nucleic acids e.g. with desoxyribonuclease or ribonuclease. Proteins and lipids are then eliminated, esp. by boiling with aq. dodecyl sulphate. When a smooth bacteris is used, the covering or walls of the cells may also be treated with water containing a surfactant to eliminate external lipopolysaccharides. The residual material comprises a peptidoglycane structure linked covalently to polysaccharides. Vaccines in which the starting bacteris is B, abortus 99S or B. melitensis 16M are specif. claimed.

Patent FR-2271418-A1 (FR)
Title: Rotating valve for positive displacements pump - gives continuous variation of discharge volume from fixed volume pump
IPC: F04C14/14
Filed: 1975-05-02
Abstract: A positive displacement hydraulic lump (1) with a fixed volume capacity discharges through a valve (2). The valve contains a rotating disc (3) which has ports (b) in a solid disc (a) and also contains a non return valve (5). When the ports pass the valve branch outlet flow is returned to the reservoir (4) without causing the pump to produce a pressure and when a solid part of the disc obscures the branch outlet the pump develops a pressure sufficient to force fluid through the non return valve to the using equipment (6). The arrangement allows the volume output of a simple and therefore cheap type of pump to be varied without the production of unnecessary pressure and consequent loss of energy.

Title: Acoustic diffusion device with delaying matrix - is used where direct sound and delayed sound from common source are combined for output
IPC: H04N5/64
Filed: 1977-03-02
Abstract: An acoustic diffusion diffusion device provides overlaying of an acoustic wave by a delays form from the same source. A bell housing contains a central unit having a loudspeaker which provides direct acoustic waves propagated on one side of the ball. A central housing inside the bell housing has a long convoluted internal path along which the loudspeaker commumincates with a passive membrance opening out on the other half of the bell. Acoustic waves are transmitted through a medium in the path to the passive membrane from which they emerge into the bell to be superposed on the acoustic waves emanating directly from the speaker.
