Abstract: A closed impregnation device (200) for impregnating a fiber reinforcement material with a thermosetting resin composition including a housing, an entry means adapted for feeding a dry fiber reinforcement material into the housing, a means for feeding a dry fiber reinforcement material through, and into, the housing, a passageway from the entry means into the housing, an injection means disposed in the housing adapted for injecting a thermosetting resin composition into the housing and contacting and wetting the dry fiber reinforcement material, a means for feeding a thermosetting resin composition through, and into, the housing via the injection means, an exit means adapted for discharging a wetted fiber reinforcement material from the housing, and a passageway from the inside of the housing to the outside of the housing adapted for allowing the wetted fiber to exit the housing.

Abstract: A process for removing contaminants from a fiber reinforcement material, the process comprising: (a) feeding a fiber reinforcement into a heated vessel, (b) passing the fiber reinforcement through the heated vessel, (c) heating a source of fluid medium, (d) feeding the heated fluid medium from (c) into the heated vessel having a passageway in the heated vessel for allowing the heated fluid medium from (c) to enter into the heated vessel, (e) passing the heated fluid medium through the heated vessel; wherein the heated vessel has a passageway for allowing the heated fluid medium from (c) to exit the heated vessel, and (f) contacting the fiber reinforcement passing through the heated vessel with the heated fluid medium passing through the heated vessel such that any contaminants present in or on the fiber reinforcement is sufficiently reduced to provide a purified fiber reinforcement exiting the heated vessel.

Abstract: A fiber-reinforced composite article useful for contaminant removal comprising at least one single layer of a fiber-reinforced composite having (a) at least one first polymer fiber-free region containing material adapted for removing contaminants, (b) at least one second polymer fiber-rich region containing fiber reinforcement material; and (c) at least one third polymer boundary region containing a portion of the first polymer fiber-free region and a portion of the second polymer fiber-rich region; a process for manufacturing the fiber-reinforced composite article; and a process for removing contaminants from a liquid fluid using the fiber-reinforced composite article.

Abstract: An amine hardener system useful for curing a curable resin composition including a blend of: (I) a first amine hardener comprising at least one cycloaliphatic amine; and (II) a second amine hardener comprising at least one polyetheramine; and a curable epoxy resin composition including (A) at least one epoxy resin compound; and (B) at least one curing agent; wherein the at least one curing agent includes the above amine hardener system.

Abstract: Phosphorus-containing compounds of formula (I): (I) wherein m, n, R, R1 and R2 are as set forth in the claims. The compounds of formula (I) can be used to provide polymers with flame retardant properties.

Abstract: A method is disclosed for providing a steady transition state for an integral pneumatic dispensing system that is related to a robot. The method dispenses a single material using a pneumatic dispensing system having a single output including first and second shotmeters having first and second meters, first and second encoders and first and second pressure transducers. The method includes the step of loading the first shotmeter with the material. Once loaded, a pressure is applied to the material. The material is then dispensed out of the first shotmeter by forcing the material through the single output. Once the material in the first shotmeter is dispensed to a predetermined volume, the method begins to transition the flow of material from the first shotmeter to the second shotmeter. The transition includes the control of the volume being dispensed and the pressure applied to the material.

Abstract: This invention relates to an improved catalytic process for the alkylation of benzene or substituted benzene with alkyl halides for the continuous production of diarylalkanes or substituted derivatives thereof using ethylaluminum dichloride or methylaluminum dichloride as an organoaluminum dichloride catalyst. A process and apparatus are provided for reacting either benzene (or a substituted benzene compound) together with either an alkyl halide or an aromatic halide.

Abstract: A tool for crimping a connector sleeve onto the ends of cable strands or the like for joining the strands together consists of an anvil arm having a V-shaped notch therein pivotally mounted relative to a base for its notch to be swung into cooperative opposed relation with a V-shaped notch in a die block on the base for crimping a connector sleeve that is placed through the die block notch.The size of the crimp opening, defined by the two notches in cooperative opposed relation, is determined solely by the size of the notch in the die block. The notch in the anvil arm is the same for all crimp opening sizes. The die block has shoulder surfaces that are engaged by end portions of the walls of the anvil arm notch to bring the two notches into precise operative alignment and to stop relative movement of the notches together when they are in the spaced relation that will produce the size crimp desired.
