Abstract: An intermediate product comprising fibres mainly distributed in two orientations forming an angle with one another is used. A spreader/lapper (13A, 13B) is fed with this intermediate product and deposits the intermediate product in alternate folds onto its exit conveyor, to form a lap of superposed layers which is such that the main orientations of the fibres in each layer form an angle with the main orientations of the fibres of the contiguous layers, and the lap is subjected to a fixing treatment, for example by means of a needling machine (14A, 14B). The invention is used for producing high-quality nonwovens. <IMAGE>

Abstract: Composition d'amalgame modifiée produisant une liaison adhésive avec une structure dentaire traitée au moyen d'un adhésif dentaire. L'amalgame modifié peut être préparé lorsqu'on mélange des adjuvants particulaires à une poudre d'alliage d'amalgame classique pour former une poudre d'alliage modifiée, puis lorsqu'on triture la poudre modifiée avec du mercure. Lorsqu'on applique l'amalgame modifié dans une cavité dentaire préparée qui a été préalablement enduite d'un adhésif dentaire fonctionnel d'acrylate ou de méthacrylate, une liaison adhésive est produite entre l'amalgame modifié et la structure dentaire enduite. Des adjuvants particulaires préférés pour la poudre d'alliage d'amalgame sont des polymères fonctionnels d'acrylate ou de méthacrylate, des sels métalliques de ces acrylates ou méthacrylates, des charges non métalliques, des agents oxydants et des agents réducteurs.

Title: Guard system for automatic doors.
Inventor: TRAN TUYEN
IPC: E05F15/73
Filed: 1992-08-11
Abstract: At least one face of one or each leaf of an automatic door has an obstacle detector (20) consisting of a movement detector arranged to generate a signal proportional to the relative movement of an obstacle in the spatial detection field of the detector with respect to the corresponding door leaf. A controller is placed to acquire the detection signal generated by the detector for each door leaf and produce a set point signal for door automation, said set point signal representing the relative movement of the obstacle having the slowest movement with respect to door leaf movement. Each movement detector consists advantageously of a Doppler detector which produces a detection signal having a frequency component porportional to the speed of a surface or obstacle moving relatively to the door leaf.

Abstract: The invention relates to a process for the treatment or recycling of polyolefins and polyolefin-containing composite materials for complete material recycling of the individual components containing one or more further synthetic polymers and/or metal and/or natural polymers. The object is to provide a process for the treatment of composite materials containing polyolefins which is technically straight-forward and unproblematic from the aspect of industrial safety, by means of which a qualitatively better polyolefin can be obtained and in addition the process can be carried out economically and ecologically. The object is achieved according to the invention by treatment with a solvent. The solvents used according to the invention are cycloalkanes, n-alkanes and isoalkanes, which are also employed as a mixture. After the insoluble components have been separated off, the polyolefin solution and an aqueous surfactant solution are dispersed in one another according to the invention. The dispersion obtained from this treatment, which comprises precipitated polyolefin, an aqueous phase and an organic phase, is then separated into its constituents in a manner known per se. The particular advantage of the process is also that specific particle sizes can be produced with optimised dry-flow properties. It is of course also possible to produce the desired particle sizes from virgin plastics using this process.
