摘要:
A mold cavity for producing a pneumatic vehicular tire is radially expandable to form successive coaxial annular layers, e.g. carcass, reinforcing belt and tread, of the tire body. The mold cavity is defined by a stationary core, several outer annular mold walls alternately juxtaposable with the core, and a pair of opposite cheeks axially bracketing the core and the juxtaposed segments. The segments of each mold wall are movably mounted on a respective carrier ring and are radially outwardly retractable thereon to clear the cheeks whereby they can be axially moved into and out of alignment with the core. With successive operative positioning of segment sets of progressively increasing inner radii around the core, the mold cavity is expanded after each molding step preparatorily to formation of the next layer after partial hardening of the elastomeric material of the layer previously formed therein.

摘要:
A drug composition containing as a drug substance a polymeric guanidine derivative based on a diamine containing oxyalkylene chains between two amino groups, with the guanidine derivative representing a product of polycondensation between a guanidine acid addition salt and a diamine containing polyalkylene chains between two amino groups, as well as the pharmaceutically acceptable salts thereof.
摘要:
The invention relates to a polymeric condensation product which can be obtained by reacting guanidine or its salt with an alkylene diamine and an oxyalkylene diamine. Said condensation product has biocidal, in particular fungicidal, activity and is usable as a plant protection product.
摘要:
The invention relates to a multi-layer or laminated compound body, in particular vehicle tire in which at least one first layer or ply, in particular on polyurethane basis, is bonded via a coupling agent layer on polyurethane basis to a second layer or ply, in particular on polydiene basis, which layer is preferably at least essentially free of polyurethane. According to the invention, it is provided that the coupling agent layer is formed of a polyenol polyurethane whose polyenol component in a manner known per se has an OH-functionality of less than 2.1, in particular of 1.7 to 2.05, preferably of 1.9 to 2.0, at preferably terminal hydroxyl groups, and/or a corresponding polyenethiol polyurethane. The invention further relates to a process for the production of the compound body and a coupling mass for performing the process.
摘要:
An apparatus for molding a tire with an annular reinforcement below the tread surface includes a first set of molding segments for molding a tire, a winding mechanism for winding a flexible reinforcement band or thread about the molded tire under tension and a second group of molding segments for molding a tread surface portion about the reinforced tire body.
摘要:
A method for molding a tire with an annular reinforcement below the tread surface in which first a tire body is molded and then a flexible reinforcement formed by bands or threads is wound, preferably under tension, in form of a helix about the circumference of the tire body, whereafter a tread surface portion is molded about the tire body and the reinforcement thereon; and an apparatus for carrying out the method.

摘要:
The invention relates to the use of polymeric guanidinium hydroxides based on a diamine which contains oxyalkylene chains and/or alkylene groups between two amino groups, obtainable by polycondensation of a guanidine acid addition salt with the diamine, whereby a polycondensation product in the form of a salt is obtained, which subsequently is converted into the hydroxide form via basic anion exchange, for controlling microorganisms.
