Abstract: A multi-compatible sizing composition that includes an epoxy resin emulsion, a silane coupling agent package, a non-ionic lubricant, and a crystalline polyol is provided. The epoxy resin desirably has an epoxy equivalent weight from 180-195. A preferred emulsifier is a modified polyethylene oxide-polypropylene oxide block copolymer. The silane coupling agent package includes an aminosilane and a vinyl silane coupling agent. The sizing composition may be used equally well with epoxy, unsaturated polyester, and vinylester thermosetting resins. Reinforcement fibers sized with the inventive sizing composition possess low friction on contact points, low fuzz, and reduced drag. Other performance characteristics such as in-plane shear and dynamic fatigue are also improved by the multi-compatible sizing composition. Fibers sized with the multi-compatible sizing composition may be used, for example, to form woven rovings and fabrics, in filament winding applications, and in pultrusion processes.

Abstract: Device for unloading a pressurized vessel, comprising at least two rotary feeders in series, a valve situated between the reactor and the first feeder, and a point of entry for a gas, that is situated between the valve and the reactor.

Abstract: A process for discharging a reactor characterized by reducing the volume of a powder without compacting it, including treating the powder in a densification zone including at least one Archimedes' screw arranged in a barrel. The Archimedes' screw may also have both a reduction in pitch and an increase in diameter of the shaft. The densification zone may also contain two co- or counterrotating screws arranged in a barrel and exhibiting a reduction in the pitch of the screws. Densification zones consisting of two co-rotating screws give particularly good results.

Abstract: An electrically heatable transparent panel (1) comprises spaced electrically conductive bus strips (2, 3) interconnected by electrically conductive heating means (4) deposited on a substrate (5) of glazing material.To reduce the visual obtrusiveness of the heating means (4) as compared with linear heating elements as conventionally used in heatable rear windows or motor vehicles, and for other purposes, the heating means comprises electrically conductive enamel deposited meshwise on the substrate, the interstices of the mesh having a maximum dimension of 10 mm or less, and substantially no individual line of mesh has a width greater than 0.5 mm.

Abstract: Apparatus composed of a control and monitoring unit 1, a thermostated cylinder 2 receiving a measured quantity of material to be evaluated, a plunger 3 sliding in the cylinder 2, an exchanger system enabling the cylinder 2 to be equipped with a suitable die 6 for the measurement to be carried out, a stepping-control motor 7 ensuring a monitored travel of the plunger 3, a force-sensor 9 yielding a signal as a function of the force applied to the plunger 3, and an electronic microprocessor system monitoring the stepping motor 7 as a function of the position of the piston and/or of the signal emitted by the force-sensor 9 at the end of the time assigned to the thermal conditioning of the measured quantity to be evaluated, the plunger 3 is situated at a distance from the die 6 permitting the measurement and acts for 10 to 180 seconds on the measured quantity according to a parameter of the speed of travel of the plunger or of the applied force specified by the measurement to be carried out.
