Patent EP-0410573-A1 (EP)
Inventor: PORUCZNIK PAUL
IPC: B26F1/44
Filed: 1990-06-20
Abstract: When a blank is cut from metal sheet which suffers from crystallographic anisotropy, there is a tendency for ears to be formed during subsequent forming operations, such as drawing or pressing. In order to compensate for this tendency, there may be used a metal blank which is not completely round, but has lobes at positions to cancel at least some of the valleys between the ears. There is described a punch (110) and die (111) which may be used to form such a lobed blank (112). The punch (110) has four circumferentially extending lobe-forming sections (124). Each lobe-forming section is constructed by forming a stepped recess in the cutting edge of the punch (110). In each lobe-­forming section, the depth of the recess varies from a maximum at the middle of the section to zero at the ends. The die (111) is conventional.

Abstract: An electrical device comprises a substrate 2,4 supporting a film-type track 8, such as a heater track formed by depositing and curing a conductive polymer ink. A connector member 5 is provided which is bonded to the substrate 2,4, by means of a suitable adhesive 7, such as epoxy. The film-type track 8 is arranged to overlie at least an end portion 6 of the connector member 5 to provide a low electrical resistance contact therebetween. The arrangement permits the connector member to be mechanically bonded directly to the substrate 2,4, and not via the film-type track 8. The device may be used as a heater for mirrors, such as in car mirrors or mirrors for other applications, such as dentistry, where misting of the viewable mirror surface can be expected to occur.

Abstract: Procédé de polycondensation d'interface de deux phases pour produire des polyesters aromatiques à partir de diphénols comportant, au moins pour la plupart, un atome central de carbone, les groupes liés à cet atome de carbone étant bloqués pour ne pas pouvoir tourner librement, en particulier 9,9-bis(4-hydroxyphényl)fluorène, avec des chlorures d'acide dicarboxylique, comme iso/téréphtaloylchlorure. Dans ce procédé, la phase aqueuse contient, avec le diphénate, de l'acétone ou du méthyléthylcétone en tant qu'agent de solubilisation, tandis que les chlorures d'acide dicarboxylique dissous dans un hydrocarbure chloré constituent la phase organique-liquide. On obtient ainsi des polyesters de poids moléculaire supérieur à ceux qui sont produits par les procédés utilisant d'autres agents de solubilisation, par exemple isopropanol. L'acétone ou méthyléthylcétone peut servir simultanément de précipitant pour le polymère dissous dans la phase organique-liquide une fois la polycondensation terminée. Les différents solvants qui sont alors utilisés, eau, acétone et hydrocarbure chloré, peuvent être séparés par rectification et réutilisés.

Abstract: La machine à laver décrite est équipée d'un capteur de nettoyage (9), qui détecte le degré de saleté de l'eau de lavage, ainsi que d'un dispositif déterminant par inférence le temps de lavage (14) qui sert à déterminer une durée du temps de lavage en fonction de la théorie des inférences floues, après l'introduction dans le dispositif d'une durée de temps nécessaire pour qu'une valeur détectée par le capteur de nettoyage (9) devienne saturée et d'une valeur détectée au moment de la saturation. Dans cette machine, le degré et la nature de la saleté évalués jusqu'à présent par l'utilisateur correspondent à la valeur détectée au moment où la valeur contenue dans le capteur de nettoyage (9) devient saturée et à la durée de temps jusqu'à la saturation, et une règle utilisée par l'utilisateur pour déterminer la durée du temps de lavage sur la base de l'état de saleté (degré et nature des taches) est établie en fonction de la théorie des inférences floues. Ainsi, une durée de temps de lavage devant être déterminée par le dispositif déterminant par inférence le temps de lavage peut être rendue égale à la durée déterminée par l'utilisateur sur la base de son expérience et de son savoir-faire et un lavage délicat dans des conditions optimales comparables à celles offertes par l'utilisateur est possible.
