This invention relates to the improvement of rubber-to-metal adhesion and adhesion retention in sulfur vulcanizable, metal reinforced rubber compositions via the use of substituted pyrimidine and triazine adhesion promoters of structure (I), wherein A is N or C-H, X, Y and Z are independently selected from the group consisting of chloro, (II) wherein R1 may be hydrogen, chloro,acyl,or C1-C12 alkyl...

This invention relates to a continuous ultrasonic method and apparatus for breaking the carbon-sulfur (C-S), sulfur-sulfur (S-S), and if desired, carbon-carbon (C-C) bonds in a vulcanized elastomer. It is well known that vulcanized elastomers having a three-dimensional chemical network, cannot flow under the effect of heat and/or pressure. This creates a huge problem in the recycling of used tires...

2138524 9400294 PCTABS00030 A method is described for making colored backed film material using a polyvinyl fluoride (PVF) film (90) having a first face and a second face opposite the first face. The method comprises the steps of coating the first face of the PVF film (90) with an ink-receptive coating (65). A carrier is then statically laminated to the second face of the PVF film. Using a rotary ...

Polyoxylalkylene esters and amides of alk(en)yl succinic anhydrides, of the formulae (I) YA1.OC(HR)CC(HR1)CO.A(CmH2mO)n.R2 and (II) YA1.OC(HR)CC(HR1)CO.A(CmH2mO)n.CpH2pA.CO(HR1)CC(HR)CO.A1Y where R, R1, A, A1, Y, R2, m, n and p are as defined, particularly where the alk(en)yl group is a C14 to C22 group, are effective surfactants. They are especially notable because, very surprisingly, the cloud p...

An air-operated combination diaphragm spring brake has a tamper-resistant seal provided between a head (46) and a spring side of a flange case (18) which together form a spring chamber (16) housing a power spring (72). The head (46) has an annular rim (70), and the flange case has an annular flange (74) with a diaphragm (48) sandwiched therebetween. An annular lip (76) on annular rim (70) extends ...

A data processing system for establishing a management environment in an organization utilizing the flow of information between a distributed network of discrete response centers. The system permits the creation of a controlling matrix of activity patterns associated with the different functional aspects of an organization such as Policies & Procedures, MIS, Accounting, Costing, etc. that govern t...

Solutions of linear aromatic poly(imideamide)s which are, on the one hand, clear at room temperature (23 DEG C) and stable in storage at the same temperature and, on the other hand, are suitable for producing especially films or varnishes exhibiting little colour. More precisely, these solutions consist: a) of gamma -butyrolactone as solvent and b) of a particular poly(imideamide) which is prepar...

Described is a process for producing foamable particles of styrenic polymers in which said particles are subjected to a partial removal of foaming agent, performed at a temperature lower than the glass transition temperature (Tg) of said particles.

A three-dimensional braid structure comprising a plurality of interlocked layers is created by causing a plurality of package carriers (15) of yarn (16) to move along a plurality of serpentine paths (6) defined by track modules. The track modules extend generally in one direction to define a longitudinally extending path corresponding to a first layer of the braid structure and in another directio...
