An absorbent cellular polymeric material is provided which exhibits enhanced water retentivity and may also exhibit enhanced compressibility. Such a material is provided by foaming the reaction product of a poly(aminoether) and an epoxy resin and quaternizing the resulting reaction product with, for example, an acid. The foam is particularly usable in products for absorbing body fluids.

An HIPR emulsion of bitumen in water is prepared by a method which comprises directly mixing 70 to 98% by volume of bitumen having a viscosity in the range 200 to 500,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant, percentages being expressed as percentages by volume of the total mixture. Mixing is effected under low shear conditions...

of the disclosure: The present application relates to a microbiological process for the preparation of compounds of the formula I I in which R denotes hydrogen or hydroxyl and R1 and R2 are identical or different and represent sugar combinations of the following composition: - Roa-dF-CinA - Roa-dF-Acu - Roa-dF=CinB - Roa-Rod-CinA or - Roa-Rod-Acu or R2 has the abovementioned meanings and R1 ...

An agent for contrast enhancement in nuclear magnetic resonance imaging is disclosed. Micellular particles such as phospholipid vesicles are associated with or enclose a paramagnetic material. The particles may be formulated with an agent, such as cholestrol, to promote vesicle stability and water exchange across the vesicle bilayer. The vesicles may or may not have antibodies or other cell recogn...

Composite shaped foam articles of manufacture and method for fabricating such articles is disclosed. The articles are formed by providing a section of foam material, treating a first surface of the section of foam material with adhesive, providing a second section of flexible foam having a surface to be joined with a surface of the first section, treating at least one of the surfaces to be joined ...

The invention relates to a device for preventing incorrect coupling of the cables which are provided for connection of a lead-acid battery to the electrical system of a current load, with the aid of a contact plate (4) which can be mounted on a mounting projection (7) which is located on the battery cover (1), consists of metallic lead and, for its part, is electrically connected to a terminal bol...

A container, accommodating powdery and similar slow-flowing material, has a pneumatic actuator on one of the inside walls to agitate the contents. The actuator comprises a flat frame over which an air-permeable cover of flexible material is stretched, this being fixed at the edges, but loose for a considerable part. A compressed air inlet (16) discharges between the frame and cover. Over the latte...

Frame side parts (7,8) are displaceable from each other along their whole length, and in like manner. Such displacement is produced by straight edges(2a)
