Title: Fluide d'epaississement par cisaillement
IPC: C09K8/516
Filed: 1981-04-08
Granted: 1985-07-03
Abstract: Fluides d'epaississement par cisaillement composes d'un materiau granulaire (argile) qui se gonfle avec l'eau present en quantite suffisante pour assurer une formation rapide d'une pate rigide, possedant une resistance d'au moins 2000 lbs/ 100 ft.2 par interaction avec la phase aqueuse utilisee, d'un materiau hydrophobe non-aqueux comprenant un materiau hydrocarbure et un agent tensio-actif et/ou un agent de renforcement, et d'une solution aqueuse comprenant de l'eau et un polymere soluble et pouvant se gonfler dans l'eau. L'argile granulaire et la solution polymere-eau sont maintenus separes par une composition intermediaire d'agents tensio-actifs hydrocarbures. Des particules discretes d'argile granulaire sont encapsulees dans la phase huileuse et des gouttelettes individuelles de la solution polymere-eau sont aussi encapsulees dans la phase huileuse donnant un materiau composite a phase d'huile continue. La phase huileuse intermediaire empeche l'interaction entre les phases de eau-polymere et argile granulaire donnant un materiau composite stable, ne reagissant pas, qui peut etre pompe jusqu'au moment ou l'enveloppe d'huile est rompue par l'application d'une force de cisaillement suffisamment elevee. Par suite de cette rupture, les materiaux reagissent entre eux donnant une pate semi-rigide a haute resistance.

Abstract: A temple end piece for a temple of a spectacle frame comprises an essentially straight first segment in the longitudinal direction of the temple, a connecting segment running downward from the first segment, and a design segment intended to fit on the head and/or behind the ear. The longitudinal design segment is carried by the connecting segment and supported, whereby this support occurs at the longitudinal center or at the lower end of the design segment, so taht at least the upper half of the design segment juts free upward toward the first segment. The connecting segment, the design segment and the transition region between the two are at least partially formed out of such material or even provided with additional elastic regions that the design segment can be deflected against elastic force. This will cause a comfortable, cushioned fit of the design segment on the ear of the wearer of the spectacles and will also cause the design segment under fairly heavy charging to be deflected in such a way that the reacting forces caused by the deflection will restore the spectacles back to their original position and not be dislodged.
