Abstract: 1. A method of producing moulded polyurethane foam upholstery comprising several juxtaposed and/or superimposed zones of different flexibility, characterised in that it involves dividing a mould (1) by arranging therein one or more receivers (2) and/or one or more separators (3) made of expanded polystyrene, simultaneously pouring different foaming mixtures of polyurethane each of different flexibility into one of the volumes defined by the walls of the separators (3) and of the mould (1) and/or by the walls of the receivers (2), covering the mould (1), subjecting the mould (1), filled with polyurethane foams, to the temperature originating from an external heat source and/or from the exothermic reaction of the foams, in order not only to polymerise the polyurethane foams but also to shrink the expanded polystyrene, this shrinkage at temperature (T) determining the transformation of said expanded polystyrene into a layer (6) of flexible material serving to interconnect the polyurethane foams of different flexibilities which had been poured simultaneously.

Abstract: Transmission-reception equipment for a bus system guarantees a reliable response of all bus receivers in a bus system preferably constructed with a shielded twisted-pair cable and having a greater length and/or higher bit rate than prior art systems. The stations are coupled to the bus system via a repeater having a primary winding and a secondary winding having the same number of turns. Two bus transmitters are connected parallel to one another and are respectively connected to the primary winding halves separated by a resistor. The bus reception equipment is connected to a series circuit of the two primary winding halves, whereas the secondary winding is connected to the signal conductors of the bus system. A voltage doubling achieved in the transmission direction is thereby not cancelled in the reception direction.

Abstract: A method for encapsulation of antineoplastic agents in liposomes is provided, having preferably a high drug:lipid ratio. Liposomes may be made by a process that loads the drug by an active mechanism using a transmembrane ion gradient, preferably a transmembrane pH gradient. Using this technique, trapping efficiencies approach 100%, and liposomes may be loaded with drug immediately prior to use, eliminating stability problems related to drug retention in the liposomes. Drug:lipid ratios employed are about 3-80 fold higher than for traditional liposome preparations, and the release rate of the drug from the liposomes is reduced. An assay method to determine free antineoplastic agents in a liposome preparation is also disclosed.

Abstract: Electrodes for electrochemical processes, especially anodes for the cathodic protection of metal substrates, e.g. reinforcing bars in concrete, comprise a conductive core which acts as a current-distributing member, an outer member which provides an electrochemically active outer surface, and an intermediate member composed of a material which is of higher resistivity, and/or which is less electrochemically active, than the material of the outer member. The higher the resistivity of the intermediate member, the more regular the current distribution along the length of the electrode. When the intermediate member is less electrochemically active, this protects the core from corrosion if the outer member is damaged by physical means or through electrochemical erosion. Preferably at least one of the intermediate member and the outer member is composed of a conductive polymer, especially one comprising carbon black or graphite as conductive filler. <IMAGE>

The periodic deflection of the measuring pipe (1) is effected electromagnetically so that the diametrically opposing parts of the measuring pipe wall (2) move in the same direction or in opposition transverse to the flow direction.  Pref. the periodic cross-sectional deformation is effected at a frequency adjacent the characteristic resonance frequency of the peripheral  oscillations of the measuring pipe (1) in the radial direction.

Abstract: For formed parts such as are used, for example, in vehicles, synthetic resins are normally used as binders for the fibre materials. In contrast, it is proposed to use gypsum binders or modified gypsum binders, which can be modified with small additions of plastics, for producing these formed parts, which accurately retain their shape even under the action of moisture. Further advantages are the non-flammability and the reduced gaseous emissions.
