Title: Anti-bed-sore mat
IPC: A47C27/05
Filed: 1987-06-10
Abstract: The present invention relates to a non-perishable and washable mat for reducing perspiration and the formation of bed sores in any bedridden invalid staying seated or lying down for extended periods, intended to be interposed between his/her body and the device on which he/she rests. This device is characterised in that over a substantially constant thickness depending on the weight of the body, the said mat 1 consists of an unstructured stack of flexible lengths of a synthetic material such as vinyl, tangled together in the form of small loops 3 preferably joined at their contact points by heating close to melting or any means appropriate for the material forming the said small loops 3, which thus, on the one hand, reduce the compression and frictional zones, preventing constriction of the local blood circulation responsible for bed sores, and, on the other hand, promote the circulation of air under the body, preventing any maceration under perspiration, and even, if required, urine or alternatively faecal matter.

Patent FR-2630429-A1 (FR)
IPC: C12P39/00
Filed: 1988-04-20
Abstract: The invention relates to a process for purification and valorisation of effluents, especially from the agri-foodstuffs or agricultural industries, using a coculture of selected yeasts, which process consists in employing under aerobic conditions two strains capable of establishing themselves in a dominant manner in a medium comprising at least the effluent in question constituting the substrate, namely a first yeast strain belonging, for example, to the species Candida kefyr, preferentially metabolising the fermentable sugar, and a second strain belonging, for example, to the species Candida valida, preferentially metabolising the by-products of residual fermentation of the first strain. This process finds its main application in the agri-foodstuffs industry, in particular in the treatment of crude whey, dairy permeates, or alternatively effluents from confectionery or vinegar manufacture or from sugar refineries.

Title: Tarpaulin or similar material having improved tear strength
Inventor: PIERRE PRUDHOMME
IPC: E04H15/54
Filed: 1990-02-06
Abstract: Tarpaulin having improved tear strength. It consists of a complex comprising two woven textile structures (1, 2), trapping between them a meshed and deformable reinforcing frame (5) based on yarns with high mechanical characteristics. The linkage of the outer fabrics (1, 2) is obtained using a layer of material having a shear modulus allowing it to break when a force is exerted on the reinforcing frame, the yarns of which retain a capacity for movement, without breakage, during the action of a force exerted through the complex in a direction parallel to its surface, to be precise in such a way that, during this action, the meshed yarns are moved and bear successively against each other until they provide a resistance opposing any progression of the said force.
