Title: Process for combustion of wood fuel and furnace and boiler system for carrying out said process.
Inventor: HILL RICHARD C
IPC: F17C9/00
Filed: 1981-03-23
Abstract: A stove or furnace for efficient combustion of wood fuel includes a vertical feed combustion chamber (15) for receiving and supporting wood fuel in a vertical attitude or stack. A major upper portion of the combustion chamber column comprises a water jacket (14) for coupling to a source of water or heat transfer fluid for convection circulation of the fluid. The locus (31) of wood fuel combustion is thereby confined to the refractory base of the combustion chamber. A flue gas propagation delay channel (34) extending laterally from the base of the chamber affords delayed travel time in a high temperature refractory environment sufficient to assure substantially complete combustion of the gaseous products of wood burning with forced air prior to extraction of heat in heat exchanger (16). Induced draft draws the fuel gas and air mixture laterally through the combustion chamber and refractory high temperature zone to the heat exchanger and flue. Also included are active sources of forced air and induced draft, multiple circuit couplings for the recovered heat, and construction features in the refractory material substructure and metal component superstructure.

Abstract: Die Erfindung bezieht sich auf Kernspin-Tomographie-Verfahren mit vollständiger Ausmessung aller zweidimensionalen Fourierkomponenten einer Kernspin-Eigenschaft und Bildrekonstruktion. Trotz unvermeidlicher Inhomogenitäten des magnetischen Gleichfeldes soll ein optimales Schnittbild erhalten werden. Die Erfindung sieht dazu eine optimal kurze Pulsfolge vor, indem zunächst mittels eines 90°-HF-Pulses (31) eine z = const Schicht bei eingeschaltetem z-Gradienten (30) angeregt wird, nach dessen Beendigung ein x-Gradient (35, 36) und gleichzeitig ein y-Gradient (40) eingeschaltet werden. Hierauf folgt ein 180°-HF-Puls (32), an den sich gleichzeitig ein z- und ein y-Gradient anschließen, so daß die Differenz zwischen der y-Gradientenwirkung (40) vor dem 180°-HF-Puls (32) und danach (41, 42) variiert werden kann. Nun folgt derjenige x-Gradient (37 bis 39), währenddessen Dauer das Kernspin-Echo gemessen wird, welches um einen festen Zeitpunkt als Symmetriezentrum entsteht. Für ein N x N-Bild (N = Anzahl der Bildpunkte z.B. 128 in einer Zeile) werden N solcher Abläufe mit jeweils unterschiedlicher Differenz der y-Gradientenwirkungen gemessen. Das erfindungsgemäße Verfahren ist insbesondere in der medizinischen Diagnostik (Zeugmatographie) einsetzbar.

Abstract: A diaphragm operated valve assembly is controlled by an electromagnetic valve assembly (10). A flat disc armature (22), which forms part of a flux path, is operable in an inner chamber (118) to modulate the flow between the inner chamber (118) and an exit port (28) in response to an applied magnetic force. The level of the effective magnetic force is a function of the armature (22) mass, and the pressure acting on the disc surface. A pole piece (16) adjacent to the flat disc armature (22) is slidably adjustable to establish a specified force to actuate the armature (22) to the closed or sealing position. This specified force is proportional to the current flow through the winding of the electromagnetic valve assembly (10). Thus the armature (22) operates to seal communication between the inner chamber (118) and the exit port (28) at a given pressure differential as a function of current flow. The travel distance between the armature (22) and a non-magnetic seal seat (21) has been minimized by spring (124) biasing the armature (22) in proximity to the seal seat (21).
