In one embodiment, the cavity can be formed, at least in part, in a pre-impregnation layer and a first and a second layer can be disposed above and below the pre-impregnation layer to further form the cavity.

In this preliminary impregnation stage, binders are used preferably in relatively small quantities.

A process for producing pressure formed synthetic resin bodies comprises (a) a pre-impregnation step and (b) an impregnation step.

The textile printing apparatus prints on an untreated textile by having a first application device to apply a pre-treat aqueous solution to the textile.

The process requires impregnation of the support prior to hydrothermal synthesis using the seeded method and may be undertaken with pre-impregnation masking.

The method is based on a transfer circulation with the aid of which chips are transported from the said pre-impregnation vessel (2) through an input conduit (9) to the said digester (1).

The present invention relates to a method for optimizing the liquor-to-wood ratio, especially in a pre-impregnation vessel and a continuous digester, when producing chemical pulp.

The principle is that chips are conveyed from a feeding-out device (5) at the bottom of the pre-impregnation vessel to the top separator (7) of the digester, together with circulation liquor.

In addition, the physical characteristics of the polyimide precursor 'salt-like' solutions permits processing into high-performance materials through the use of standard prepregging and composite fabrication equipment.

An apparatus and method for ink jet printing on textiles is disclosed, wherein the steps of pre-treating, ink jet printing, and post-treating the textile takes place at the ink jet printer.

Carbon nanotubes (CNTs) are so long that they cannot be penetrated inbetween carbon fibers during a prepreg preparation process, and are shortened in order for them not to be filtered out by the carbon fibers.
