摘要： A process for the manufacture of microfiltration membranes from aromatic polyamides, of which the pore sizes are between 0.05 and 10 .mu.m. A copolymer of isophthalic acid and m-phenylenediamine is dissolved in a solvent mixture of dimethylacetamide and dimethylformamide in the presence of alkali or alkaline earth chlorides and polyethyleneglycol. This solution is produced without the addition of water and is subsequently poured out onto a smooth surface formed of chemically inert material with the formation of the membranes. The water that is required as the precipitation agent, is only added to the poured-out solution by means of the air humidity. The relative air humidity is increased from 30% to 100% during formation of the membranes.

摘要： A filtration or diffusion cell, consisting of adjacent facing support plates and cut diaphragm sections of a semi-permeable diaphragm, for the treating fluids. The support plates are sealed by stringlike or bandlike sealing elements for the separate flow conduction of the fluids. Support plates are provided with channel grooves, for holding the sealing elements. The channel grooves are open toward the plate plane and are provided with perforations through which a sealing material inserted in a flowable state and solidified in the grooves. Several support plates are connected by the sealing material to form a plate holder-like unit, and form seals for separate flow conduction. The support plates are square-shaped, and the front side and the back side of the cut diaphragm sections are subjected to crosswise flow of the fluid. The cut diaphragm sections are supported by grooves and groove crests extending in flow direction of the support plates. The grooves are provided with longitudinally spaced passages leading to the opposite side of the support plates. Flow barriers crossing the grooves under an angle of about 45.degree. bring about a uniform overflowing of the diaphragm surfaces and prevent shortcuts.

摘要： A continuous process for manufacturing foam beads using a simple apparatus, wherein the expansion agent can be easily recycled. Polymer particles and a dispersing medium are fed continuously to an unstirred mass transfer column having a high length to diameter ratio which is operated under pressure. The polymer particles and dispersing medium are subjected to thermal processing under pressure in the mass transfer column, and the resulting dispersion is sprayed into a low pressure space causing the polymer particles to expand. Accordingly, foam beads of constant quality and a uniform cell diameter and a uniform degree of expansion are manufactured without costly process means.

摘要： A filter consisting of connected upper housing and lower housing parts and a hydrophobic flat filter disc for gas filtration sandwiched therebetween, intended in particular for an exchange between a container such as a liquid reservoir partially filled with liquid and the surrounding atmosphere. The upper housing part includes an integral channelled filter support having channels for communication into a gas inlet-outlet means of the said upper housing part. The lower housing part includes an integral, channelled filter support having channels for communication into a centrally disposed bore located at a right angle to the filter support and empties into the gas area of a liquid reservoir for instance. The filter support is constructed to prevent liquid from completely blocking the hydrophobic filter disc.The filter support of the lower housing forms a planar plane with an annular channel therein and a series of radially extending channels terminating at a centrally located bore. The channels having a controlled depth. The bore diameter is also controlled. The upper housing is dimensioned to provide a controlled distance for the filter from the filter support in the lower housing.
