摘要:
A regenerative fuel cell system is provided having at least one hydrogen storage container fluidly coupled to at least one hydrogen generator and at least one power generator. Each power generator further includes a fuel cell fluidly coupled to the hydrogen storage container, an electric energy storage device, and an unregulated dc bus electrically connected to said fuel cell and said electric storage device. The system further provides for a health monitoring system for determining the occurrence of critical events which may necessitate the disabling of the system.
摘要:
A batch system wherein a constant, metered flow, is established for each of the ingredients of the batch. Having a constant flow rate and constant pressure in the fluid flow, a diverter valve diverts the flow for a predetermined length of time to yield a predetermined volume of each ingredient. Since each ingredient is in a separate flow path, the diverter valve can provide one ingredient at a time, or a plurality of ingredients at a time. A computer controlling the system stores various recipes or batch formulas.
摘要:
A method of controlling air pressure in a chamber, wherein the air pressure in a chamber in which laser measurement is conducted is maintained at a set level with respect to the variation of an external air pressure, characterized by comprising detecting the external air pressure, determining a long-standing flat pressure value with respect to short-term fluctuation of the detected external air pressure, preparing a set inside-chamber air pressure by adding a predetermined air pressure to the flat pressure value thus determined, and detecting an inside-chamber air pressure while introducing an outside air so that the inside-chamber air pressure reaches the set air pressure.
摘要:
A multiple tank flow system in which a plurality of liquid storage tanks or reservoirs are connected with their outlets in parallel with the piping arranged so that the outlet from each tank shall have the same or similar pressure drop at a specific flow rate. A surface tension retaining device is mounted within each tank at the oulet opening to prevent the pressurization gas within the tank from entering the outlet while liquid is still flowing from one or more of the tanks within the system. The surface tension device can be of any suitable design such as a saucer-shaped arrangement having relatively thick, flat support members forming the structure with suitable screen-type material positioned across the entire outer surface of the support members. The size of the openings within the screen material is arranged to provide an adequate surface tension film to produce a required liquid/gaseous interface to prevent the pressurization gas from entering the tank outlet.

Die Erfindung betrifft ein Verfahren zum Betrieb von Tanklagersystemen im festverrohrten Verbund mit Rohrsystemen für Flüssigkeiten, insbesondere zur Anwendung in hohen mikrobiologischen Qualitätsanforderungen unterliegenden Anlagen zur Produktbearbeitung und zum Produkttransfer in der Nahrungsmittel- und Getränkeindustrie, der Pharmazie und der Biotechnologie, das derartige Qualitätsanforderungen erfüllt und es darüber hinaus ermöglicht, die Vorrichtung zu seiner Durchführung einfacher als mit vergleichbaren bekannten Vorrichtungen auszugestalten. Dies wird verfahrenstechnisch u.a. dadurch erreicht, dass die Zufuhr der Flüssigkeiten in den und die Abfuhr der Flüssigkeiten aus dem jeweiligen Tank (1.i) von unten erfolgt, dass die zu- oder abzuführenden Flüssigkeiten einen mit dem jeweiligen Tankinhalt in unmittelbarer Verbindung stehenden Raum (Bia) unterhalb des jeweiligen Tanks (1.i) durchströmen und dass die jeweilige Flüssigkeit in diesem Raum (Bia) in unmittelbarer Nähe zu dessen innerer Begrenzung von den an diesen Raum herangeführten Rohrleitungen des Rohrsystems wahlweise, schaltbar und vermischungssicher abtrennbar ist. Die Vorrichtung zur Durchführung des Verfahrens ist versehen mit jeweils einem in einem Tankboden (1.1a, 1.2a, ..., 1.na) des jeweiligen Tanks (1.1, 1.2, ..., 1.i, ..., 1.n) ausmündenden Ventilverteilerbaum (B1, B2, ..., Bi, ..., Bn), der als langgestreckter Hohlkörper (B1a, B2a, ..., Bia, ... Bna) ausgebildet, der im wesentlichen senkrecht orientiert ist und der Anschlussöffnungen (17) zum Verbinden seines Innenraumes mit jeder der Rohrleitungen (2.1, 2.2, ..., 2.i, ..., 2.n; 3.1, 3.2, ..., 3.1, ..., 3.n; 4) besitzt, und mit jeweils einem in seinem Sitzbereich vermischungssicher ausgestalteten Ventil (V C ; V R ; V R* ; V S ), das in jeder Verbindung zwischen der Rohrleitung (2.1, 2.2, ..., 2.i, ..., 2.n; 3.1, 3.2, ..., 3.1, ..., 3.n; 4) und der zugeordneten Anschlussöffnung (17) angeordnet ist und diese Verbindung in unmittelbarer Nähe zum Hohlkörper (B1a, B2a, ..., Bia, ..., Bna) schaltet (Figur 2).
