摘要:
A system monitors signaling data transmitted between routers. The system includes at least one router that communicates signaling data via a session with at least one other router. The system also includes a network element that receives a copy of the signaling data via a control session established with the at least one router. The sessions, including the control session, can be border gateway protocol (BGP) sessions. The network element can also operate as a BGP control server or a centralized policy manager.
摘要:
An apparatus for measuring the blood oxygen level of a patient is disclosed. In one embodiment, the apparatus includes a housing having an interior surface of non-reflective material substantially surrounding an interior. A cooperating light source and detector are operatively positioned proximate the interior surface so as to emit and receive light projected within the interior of the housing. A material more conducive to light transmission, reflectance, or a combination thereof—as compared to the interior surface material—is positioned proximate the light source and/or detector.
摘要:
The block copolymers according to the invention which are based on conjugated diolefins and polar monomers and are prepared in the presence of catalysts based on the rare earth metals have a high cis-1,4 content in the polydiene block and, because of their polar polymer part and their non-polar diene polymer part, can be used as agents which impart compatibility in the preparation of vulcanizates with a filler content for the production of tires and tire component in the preparation of thermoplastic elastomers or in the modification of thermoplastics.
摘要:
The invention relates to rubber compounds that contain rubbers polymerized in solution with a secondary hydroxyl group content of 0.1 to 5 wt.- % that are not more than 4 carbon atoms away from the respective side chain end. The invention also relates to mixtures thereof with fillers, optionally additional rubbers and rubber auxiliary agents and the vulcanized rubbers produced thereof. The inventive rubber compounds are useful for producing highly reinforced, abrasion-resistant molded bodies, especially for producing tires that are characterized by excellent non-skid properties on wet surfaces.
摘要:
The present invention relates to a process for the production of rubber mixtures containing 1 to 500 parts by weight of one or more water-repellent fillers with a methanol wettability of ≧5 wt. % to 100 parts by weight of rubber, characterized in that said water-repellent fillers are blended with one or more rubber latices and the mixture is then processes jointly, and also to rubber mixtures that can be produced with this process. The present invention relates furthermore to the use of the rubber mixtures produced by the process according to the invention for the production of tires, treads or molded articles of all kinds.
摘要:
Hydrophobic, oxidic and/or siliceous fillers obtainable by treating an oxidic and/or siliceous filler with 0.1 to 50 parts by weight, per 100 parts by weight of filler, with an adduct of sulfur and unsaturated primary and/or secondary alcohols with 3 to 60 carbon atoms at temperatures of 20 to 250° C., wherein the adduct has been obtained by reacting 1 to 10 moles of sulfur per mole of double bonds in the alcohol.
摘要:
A rubber mixture containing at least one rubber component, at least one filler, and conventional additives that it contain at least one first gel as a filler, which is essentially comprised of a rubber, has a particle size of 3×10−9 to 1×10−6 m, and has a swelling index in toluene of 1 to 15, and at least the surface of this gel has acid or base groups, where these groups have not been produced by means of reaction with dithiophosphoric acid, and comprises: a) at least one second gel as an additional filler, which is essentially comprised of a rubber, has a particle size of 3×10−9 to 1×10−6 m, and has a swelling index in toluene of 1 to 15, which is in a position to undergo a neutralization reaction with the acid or base groups of the first gel and/or b) contains at least one substance as an additional additive, which is capable of undergoing a neutralization reaction with the acid or base groups of at least one gel. The rubber mixture demonstrates an improved hysteresis behavior in the vulcanized state so that, with the use of this rubber mixture in tires, for example, the rolling resistance is reduced and the wet slippage behavior is improved in relation to the conventional rubber mixture. Methods of formulating such rubber mixtures are also provided.
摘要:
Rubber mixtures prepared from at least one styrene/butadiene rubber gel and at least one rubber which contains double bonds and optionally further fillers and rubber auxiliary substances are in particular suitable for the preparation of vulcanizates having unusually high damping at temperatures of from -20 to +20.degree. C. as well as unusually low damping at temperatures of from 40 to 80.degree. C. The rubber mixtures may therefore be used, for example, to manufacture vehicle tires which grip in the wet and have low rolling resistance.
