Abstract: The present invention involves a process for producing fine powder suitable for the preparation of antifungal polyene microlide-containing liposomes upon suspension in an aqueous solution. This process comprises the following steps. Quantities of polyene macrolide and phospholipids are dissolved respectively in a first solvent and a second solvent to form a first solution and a second solution. The first solution and the second solution are mixed in a desired ratio to form a mixture. The first solvent and the second solvent are then removed from the mixture, for example by evaporation, to form a residue. The residue is then dissolved in a third solvent comprising tertiary butanol and methylene chloride to form a third solution. The third solvent is then removed from the third solution to form a remnant. The remnant is then dissolved in a solvent consisting essentially of tertiary butanol to form a fourth solution. The fourth solution is then filtered through a filter having orifices of between about 0.05 and 0.5 micrometers in diameter to produce a filtrate. The filtrate is lyophilized to remove the tertiary butanol and a fine powder remains. This fine powder may be used to form polyene macrolide-containing liposomes by simple incubation or suspension in an aqueous solution.

Abstract: The object of the invention is to develop a known transmission system for digital and analog signals with a radio transceiver and at least one peripheral unit connected via line connections to a microcomputer control block so that a minimum number of lines are required for two-way transmission. Moreover, the line connections are intended to emit virtually no radiated interference and to be virtually unaffected by interference radiated from an external source. The object is achieved in that a pulse filter (55, 56) is provided in each case at the data outputs (50, 51) of the ports (52, 53) of the control blocks (11, 18) of the radio transceiver (10) and the peripheral unit (14). The two-way data signal line (57) is provided in a wired AND structure between a pull-up resistor (63) at the data output (50) of the microcomputer control block (11) and a pull-up resistor (64) at the data output (51) of the microcomputer control block (18). Further peripheral units (19) are connected at branching points of the two-way data signal line (57). A preferred field of application for the invention is a radio telephone system. The drawing shows a block diagram of a transmission system according to the invention. (Fig. 2) <IMAGE>

Abstract: This invention relates to a method to establish a conference connection between a plurality of conference nodes (2, 4, 8) arranged in a telecommunication network (1); and also to a node design (30; Fig 3) of such a conference node. The conference according to this invention is set up on a per call basis. Any of the conference nodes (2, 4, 8) shall, each time it activates, access a free information resource (11) among a plurality of resources (11, 12,...,n) and transmit it's message to this resource; while all the conference nodes during all the conference time, are listening to the messages present on all the activated or occupied resources. The maximum number of active (i.e. transmitting) conference nodes correspond to the total number of information resources. The maximum number of passive (i.e. listening) nodes are unlimited. A node is typically moving from a passive state to an active state and back again to the passive state leaving the resource unoccupied. Each resource may preferably be designed as a ring connection via which all the conference nodes are interconnected as the ring is looped through passive conference nodes, but where each activated ring connection is broken, only at one place, but in a dynamic manner, at the input of the active node associated with just this ring, which active node accesses this particular resource during the activated time period of just this node. The invention is well suited for digital crypto conferences, as speech decoding and decrypting is undertaken at each conference node input, while encryption and speech coding is done at each conference node output. In addition the invention is easily adapted to an Integrated Services Data Network (ISDN). Echo suppression, as well as addition and subtraction of conference signals, are totally avoided. The crypto keys to be used in such a crypto conference, may be distributed among the conference participating nodes before the conference starts; and/or they may be altered during the conference, in short lasting pauses in the conference, or on a free resource, or via the D-channel in the ISDN implementation. <IMAGE>

Abstract: A method is disclosed for recovering high-purity trimethylbenzenes from mixtures in which such compounds are contained together with ethyl-toluenes and possibly also butyl-benzenes, which method consists of treating such a mixture with benzene in the presence of a heterogeneous acidic catalyst selected from the group consisting of the so-said acidic earths and some types of porous crystalline catalysts in their protonic form, under conditions of transalkylation, and of subsequently separating the trimethylbenzenes by distillation. In fact, the transalkylation with benzene makes it possible ethyl-toluenes and in particular 2-ethyl-toluene to be preferentially or selectively converted into toluene and ethylbenzene, and any possibly present butyl-benzenes to be drastically reduced in amount, thus enabling an easy separation of trimethylbenzenes and in particular of pseudocumene and mesitylen to be accomplished by means of a simple distillation step.

Abstract: A method of maintaining a given content of a substance A in an aqueous solution where it is continuously consumed and where the redox potential E, at least within the range of concentration used, approximately satisfies the equation:    E = G + F(x)   wherein x is the content of A, F is a function of x whose derivative dF/dx approaches zero when x assumes a high value, and G on the whole is independent of x but is influenced by other parameters, such as pH, temperature or the like. The addition of A is controlled in such manner that a set value of the redox potential is maintained. The set value is determined by increasing or decreasing the addition of A in a predetermined manner, whereupon the redox potential is measured, and the measured value is used for determining the set value. <IMAGE>

Abstract: In the injection molding of closure caps, the problem of demolding the safety-seal strip, which is suspended at an intended break line and is necessarily provided with undercuts, is encountered. Here a clearance must first be created at the lower outer surface of the safety-seal strip, and the safety-seal strip must then be stripped from the mold core together with the closure cap. As a practical method step, the invention proposes to bring about the release of the lower portion of the outer surface of the safety-seal strip by lowering a mold ring which is displaceable relative to the stripper plate.

Abstract: A control system for a textile dying apparatus processes and distributes digitally encoded pattern information. A substrate is moved on a path along which the surface of the substrate comes into operative range of a plurality of arrays arranged along the path of the substrate. Each of the arrays has a plurality of individual dye applicators capable of selectively projecting a stream of dye onto a predetermined portion of the substrate corresponding to a pattern element in a pattern composed of a pattern element matrix with a plurality of pattern elements in each of a plurality of pattern rows. Each pattern element is associated with a visually distinct pattern area. The dye applicators project dye for a time period determined by the pattern information. The method first determines a set of initial values. From the initial values it generates a firing command matrix having, for each dye applicator in each array, a firing command sequence corresponding to the pattern element to which that dye applicator may apply dye in each pattern row. Finally, the method allocates, for simultaneous transmission to each dye applicator in each array, the firing command sequence in the firing command matrix corresponding to the pattern element in the pattern row to be applied to the predetermined portion of the substrate that is passing within operative range of the dye applicator at the time of transmission. <IMAGE>
