  • Patent number: 5264501
    Abstract: This invention pertains to alkyl substituted bi(cyclohexylamine) and derivatives having a high trans,trans-isomer distribution. This isomer distribution represents a thermodynamic mixture of the isomers and provides for extended pot life and extended thermal properties in epoxy resins which are not seen with the kinetic isomer mixture. The bridged cyclohexylamine and derivatives are represented by the formula: ##STR1## wherein; R.sup.1 is hydrogen or C.sub.1-4 alkyl;R.sup.2 is C.sub.1-4 alkyl; andR.sup.3 is hydrogen or C.sub.1-4 alkylThe invention also relates to epoxy resins cured with the bridged bi(cyclohexylamines).

  • Patent number: 5109510
    Abstract: A method of, and apparatus for, running several applications concurrently on a processing system. Virtual terminals are created for running the applications. However, the virtual terminals perform as though the processing system were a single terminal system. In this way, any application written for a single terminal system can run in this multiple virtual terminal environment. For interaction with one of the several applications running on this system, the real physical resources of the system are reallocated to the virtual terminal running the selected application.

  • Patent number: 5066764
    Abstract: This invention relates to ditertiary-butyl substituted bridged di(cyclohexylamines) where the tert-butyl substituent is alpha to the amine group and to polyepoxide formulations incorporating the di(cyclohexylamine). The formula of the diamine is: ##STR1## wherein R is tert-butyl. The di(tertiary butyl)methylene bridged cyclohexylamines have delayed reactivity when incorporated in epoxy resins and they also enhance physical properties in high resilience polyurethane foams.

  • Patent number: 5025078
    Abstract: This invention relates to polyepoxide resins cured with an amine composition containing 1-methyl-2,6-cyclohexanediamine. The resulting polyepoxide resins generally are more easily processable and have improved thermal stability, greater elongation and enhanced fracture toughness.

  • Patent number: 4946925
    Abstract: This invention relates to bridged cyclohexylamines represented by the formula: ##STR1## A is C.sub.0, --CH.sub.2 --, ##STR2## R.sub.1 is C.sub.1-3 alkyl R.sub.2 is C.sub.1-6 alkylR.sub.3 is C.sub.1 or C.sub.2 alkylR.sub.4 is H or C.sub.1-4 alkylx is 0 or 1y is 0 or 1These bridged bis(cyclohexylamine) derivatives are well suited as curing agents for epoxy resins. These compositions lead to enhanced processing of the epoxy resin and permit adjustment of the reactivity/performance in formulating epoxies which demonstrate superior high temperature properties.

  • Patent number: 4560096
    Abstract: The disclosure relates to a bag and is intended to receive a load. The bag has gripping handles and hooks for securing the bag to the mobile container body, the securing hooks being employed when the bag cooperates with the container body and inactive when the bag is not cooperating with the container and, inversely, the gripping handles being inactive when the bag is cooperating with the container and active when the bag is not cooperating with the container.

  • Patent number: 4410940
    Abstract: A method for transferring control between hierarchically related cooperating sequential processes P and Q executable in a multi-processing CPU environment. The method uses pointers to identify active and suspended processes. The method steps comprise generating and memory storing activation records; transferring control from process P to process Q, and updating the process pointers to record the suspension of process P and the activation of process Q; and resuming execution in the most recently executing subprocesses of Q by reference to the process pointers.There is stored in memory one activation record per process. The record includes a pointer to the activation that is the parent of the process, a pointer to the most recently executing subprocess of the process, and information defining the current execution state of the process. These pointers are further constrained such that the set of activation records form the nodes of a tree whose arcs are defined by the parent pointers.

  • Patent number: 4316922
    Abstract: The combination of n-butanol, n-hexanol and butoxyethanol, is a superior formulation solvent for aqueous dispersions of amine-neutralized, phosphorylated DGEBA-type epoxy resins which are to be applied to container interiors by spraying. Good film rheology and control of viscosity--by adjusting the solvent to organic solids ratio--is attained at total solids content as low as 20 wt. % and at VOC's as low as 3.5 lbs. per gallon.
