Inventor: GUDERNATSCH WILHELM DIPL-ING
IPC: C12M1/12
Filed: 1989-12-01
Abstract: In the process for separating at least one component, especially of solvents, from a fluid mixture, the fluid mixture is taken past a selective membrane (2) and separated at the latter by a permeate-side partial pressure, which is lower than that of the fluid mixture, into a permeate, whose concentration of component to be separated off is higher than that of the fluid mixture, and into a retentate, whose concentration of component to be separated off is lower than that of the fluid mixture. The permeate is heated (5). In order to recover the components to be separated off in a concentrated form at low cost, the permeate from the selective membrane (2) is taken past a concentrating membrane (7) having a selectivity inverse to that of the selective membrane (2). At the concentrating membrane (7), the permeate is separated by a partial pressure at the end-permeate side, which is lower than the pressure of the permeate taken past, into an end permeate whose concentration of component to be separated off is lower than that of the permeate from the selective membrane (2), and into an end retentate whose concentration of component to be separated off is higher than that of the permeate from the selective membrane (2). <IMAGE>

Abstract: An interface device which is provided with a DC-DC converter and a power output terminal so that the internal circuit of the interface device and the external equipment may share a common power source in spite of their different power supply requirements, and the wiring connection between the interface device and the external equipment may be simplified. In particular, if the interface device is configured as a terminal base and coupled to the controller via serial transmission line, a significant simplification of the wiring between different parts of the controller system can be accomplished. If the power terminals comprise positive and negative power output terminals arranged in an alternating fashion, and the power terminals and the signal lead terminals are arranged in two different rows, preferably, in staggered relationship, the leads from different pieces of external equipment may be clustered close to each other, and the external wiring work is extremely simplified. This contributes to the elimination of wiring errors and the reduction in the cost of installing the controller system.

Abstract: Afin de régler la luminosité d'un affichage à cristaux liquides fluorescent (1), on place une photodiode (7) adjacente à un bord (9) d'une cellule d'affichage (2). La photodiode reçoit la lumière (8) ayant été réfléchie totalement de manière interne à l'intérieur de la cellule et ainsi émise à partir du bord de la cellule. La fluorescence émise demeure sensiblement constante pendant la commutation de l'affichage, et constitue une mesure de la luminosité de l'affichage. La sortie de la photodiode est amenée à un circuit (10) réglant la luminosité de la source lumineuse (5) éclairant l'affichage, de sorte que l'on obtient une luminosité d'affichage sensiblement constante.

Abstract: A spout fixture (11) for bathtubs, wash basins or the like has a body (12) with a thin horizontal water emission zone (21) from which a sheet-like flow of water is directed along the underside of a flow guide (23) to a discharge zone at the end of the flow guide. The flow guide undersurface (24) curves downwardly as the discharge zone is approached enabling momentum and adhesion to hold the flow on the downwardly facing surface against the pull of gravity. Water released from the end of the flow guide travels downwardly into the receptacle in the form of a free falling, thin, smooth curtain of water that minimizes noise and splashing and is attractive in appearance.

Abstract: To form titanium nitride layers, which are used as adhesive, contact and barrier layers in VLSI circuits, a chemical vapour-phase deposition process in a multichamber high-vacuum system is employed. The choice of a nitrogen-containing organic titanium compound as starting substance and the use of thermal, optical and/or plasma excitation makes it possible to deposit layers even at low temperatures in the range 200-550 DEG C. The layers obtained are notable for a high edge coverage even with narrow vias and for good electrical and chemical properties. An apparatus in accordance with the invention for carrying out the process comprises a multichamber high-vacuum system whose chambers (1 - 6) are linked by high-vacuum locks (7), with the result that a particularly advantageous combination of several different processes is possible without interrupting the high-vacuum conditions.

Abstract: For preparing an oxide-ceramic superconductor which, in addition to copper, also contains at least two metals selected from the group comprising Y, Ba, Ca, Sr, La, Tl, Pb or the rare earths, for example YBa2Cu3O7-x, an aqueous solution is prepared which contains the metal components of the superconductor in the form of soluble salts in the calculated atomic ratios. By combination with at least the equivalent quantity of an oxalic acid solution, the metals are precipitated as oxalate, the mixture of the oxalates is separated off and dried, and the powder is heated up to thermal decomposition and is then caused to react in the presence of oxygen to give the superconductor. In this case, 3 to 10 % of the metal salt solution to be converted are initially combined with the oxalic acid solution. The resulting precipitate is filtered off and discarded. The filtrate is combined with the remainder of the metal salt solution. The resulting precipitate is filtered off, dried and further processed to give the actual superconductor.

Abstract: As shown in Figure 1, a pulse generator comprises a digital oscillator (1) which produces a succession of numbers from which a periodic analogue waveform is produced. These numbers can represent a triangular waveform (TW) (or a sine waveform). Their direct conversion into analogue form by a digital-to-analogue converter (3), followed by integration by an integrator (4), would result in the production of a distorted analogue waveform (SW) which when limited by a limiter (5) would produce an output pulse waveform (OPW) with an inaccurate mark/space ratio. The invention provides a subtraction circuit (2) which subtracts each number produced by the digital pulse generator (1) from the previous number, to produce a series of new numbers (MW) which represent a pre-distorted waveform. When these new numbers are converted into analogue form, the integration of the resulting waveform (MW') by the integrator (4) produces an analogue waveform (SW) with clearly defined zero crossings. The output pulse waveform (OPW) is thereby given a reliable mark/space ratio. Furthermore, when the pulse generator is driven by a clock whose frequency is several times greater than the frequency of the output pulse waveform (OPW), the latter suffers only small phase modulation (jitter).
