Patent CA-2198388-A1 (CA)
Inventor: BOLTE GERD DR
IPC: C08G18/79
Filed: 1995-08-14
Abstract: L'invention concerne des compositions de polyuréthanne à faible teneur en diisocyanates monomères. A cet effet, on utilise de préférence des isocyanates trifonctionnels dont la fonctionnalité est éventuellement réduite à 3,0 ~ 0,7 au moyen d'agents de rupture monofonctionnels. Les compositions contiennent alors des proportions nettement plus faibles d'isocyanates fortement volatils. Ces compositions peuvent être utilisées sous forme d'adhésifs réactifs à fusion, d'adhésifs de contrecollage, d'adhésifs et de matériaux d'étanchéité, de primaires ainsi que dans la fabrication de matières plastiques expansées à partir de récipients sous pression jetables (bombes aérosol). La faible teneur en diisocyanates monomères volatils permet de réduire de façon significative les frais liés aux mesures de sécurité du travail, et facilite en outre considérablement l'élimination des résidus dans les contenants.

Title: Coupling structure and cloth stretching frame using said coupling structure
Inventor: YAMAWAKI SHIGEHIRO
IPC: B44D3/18
Filed: 1996-06-17
Abstract: Members to be coupled have hollow coupling parts at opposite side surfaces, a coupling member has, at opposite ends, press-fitting parts which are press-fitted in the hollow coupling parts, and angle shape concavities and convexities having crests which are corrupted upon press-fitting are formed on at least either one of an inner peripheral surface of the hollow coupling part and an outer peripheral surface of the press-fitting part. When the opposite end parts of the coupling members are press-fitted in the hollow coupling parts of the members to be coupled, the crests of concave parts of the angle shape concavities and convexities are corrupted by the opposed surface so as to be made into close contact with and firmly coupled to the associated surface. Thereby it is possible to securely couple a pair of members to be coupled by means of a simple press-fitting operation.
