The lipophilic anthracyclines are used for the therapy of tumours which have become resistant to treatment with initially active hydrophilic anthracyclines. Such a composition contains a lipophilic anthracycline and, if desired, a hydrophilic anthracycline primarily active against tumours. A process for the production of such a composition is furthermore described.

A porous membrane for separation of undissolved constituents from an aqueous medium comprises a support matrix (11a) with through-passages (22), an inner layer (11ba) of particles of aluminum hydroxide and/or at least partially hydrated aluminum oxide with a mean particle size exceeding 0.1 micron and an outer layer (11bb), of colloidal particles, substantially insoluble in the aqueous medium and ...

A burner for burning liquid or gaseous fuels, especially heavy heating oil. A central fuel lance is surrounded by two annular channels that supply primary and secondary combustion air. The annular channels are surrounded by several outer fuel lances that are distributed along the arc of a circle and can optionally be displaced axially and by air nozzles that convey tertiary combustion air. The obj...

A separation device designed to effect substantially continuous separation and/or fractionation operations as in, for example, ion exchange or other solid-fluid contacting systems. Also disclosed and claimed is a method for effecting such continuous treatment of plural fluid streams. The device is characterized by its construction to permit treatment of plural streams simultaneously and continuous...

A photoresponsive device incorporating a back reflector (28) disposed between a substrate (11) and a photoactive semiconductor body (26) and formed of an alloy to promote adhesion of the substrate and semiconductor body to the reflector and to prevent diffusion between the reflector and the semiconductor body. The reflector may be deposited by sputtering to avoid agglomeration. The reflector may p...

The plate profile (2) has a large number of apertures and is covered by a transparent, sealed and rigid sheet (6). It is therefore light-permeable in its entirety and at the same time adequate strength is maintained.

The heating equipment (15) and fans (14) for warm air circulation are located in the space (12) between the two drying chambers (10,11). Two wall parts (16,17) guide the forced air current through either the one (10) or the other (11) drying chamber.

The invention relates to a glazed panel which can be used for the construction of transparent structures. The panel comprises a thermally toughened sheet of glass (1), originally flat, curved when cold and maintained bent under constraint by a curved rigid frame (2). The panels are easily assembled by their frame (2) in order especially to form covering structures which are lightweight and ha...
