Patent EP-0026726-A1 (EP)
Inventor: ARTOIS FERNAND
IPC: B28B19/00
Filed: 1980-09-24
Abstract: The method makes it possible to provide flexible insulators, for example in the form of felted slag-wool or glass-wool mats or of panels consisting of organic foamed material, with effective protection of the surface without impairing their insulating properties and to impart to them a sufficient mechanical strength which makes it possible to dispense with complicated holding devices and formwork during installation. The surfaces of the mats or panels are coated by spraying with a colloidal cement mortar consisting of cement and a just sufficient quantity of water and may, if required, also contain additives. The colloidal cement mortar is a mixture of cement and water with a mixing factor water/cement of 0.25 - 0.40; the additives can be water- repelling oxide mixtures, alkali metal silicates, silicones and, if required, fillers such as, for example, sand. Each panel or mat (10) is surrounded by a layer (20) of colloidal cement mortar. The illustrated composite comprising mats (10) and cement-mortar layers (20) is provided with an outer hard shell (21) which likewise consists of colloidal cement mortar. <IMAGE>

IPC: G11C17/14

Abstract: Monolithically integrated read-only memory having parallel word lines, read lines crossing the latter and coupling elements arranged at selected crossing points, which coupling elements can be activated via the word lines and connect the read lines to the reference potential when in the conductive state. The aim here is for space-saving programming which is still able to be carried out once the levels of metallisation have been applied. This is achieved by providing at all the crossing points field-effect transistors, of which those arranged at the (non-) selected crossing points are changed with respect to the loading states of their gate insulating layers by means of an electron beam scanning their channel regions, so that the changes in their turn-on voltage thereby brought about determine their (non-) use as coupling elements. Applications include programmable read-only memories. <IMAGE>

Abstract: On pallie aux insuffisances dans les dispositifs electriques du circuit a electrode fendue d'un four a arc - en eliminant la fonction conductrice de courant des machoires de retenue par un dispositif de raccordement axial tout en deplacant le trajet des conducteurs de courant vers un niveau superieur a celui du bras porteur, - en introduisant une electrode a noyau metallique et - en prevoyant une couche protectrice en agglomerat. Le dispositif de raccordement axial est constitue par un ecrou de support a noyau metallique relie par un organe de contact, forme par des anneaux en cuivre de forme tronconique, a une cloche appropriee a cet organe. Le courant est amene au noyau metallique de l'ecrou de support par les anneaux de contact et parvient par celui-ci a l'electrode. L'electrode a noyau metallique est du type a electrode en graphite dans laquelle est scelle un noyau metallique en un alliage d'aluminium. Cet alliage garantit un contact irreprochable avec le graphite tout en evitant toute formation de fissures dans ce dernier due au chauffage de l'alliage au-dela de son point de fusion et a sa solidification subsequente. L'emploi d'une couche protectrice en agglomerat n'est possible qu'a partir du moment ou l'on fait appel a un dispositif de raccordement axial conjointement a une electrode a noyau metallique; cette couche permet une protection sure contre l'oxydation du graphite meme dans la plage des temperatures de 350 C-600 C. Elle a comme constituants un agglomerat d'aluminium et au moins un verre fusible en-dessous de 350 C, et/ou un oxyde vitreux. On les applique en une etape unique au moyen d'une machine de projection pour l'aluminium et d'un pulverisateur; le verre et/ou les oxydes vitreux sont adjoints sous forme solide, comme poudre seche au jet de gouttes d'aluminium fondu.
