Die Erfindung betrifft ein Verfahren zum Steuern von Garprozessen, insbesondere von Delta-T-Garprozessen, bei dem das Gargut in einen bereits, insbesondere auf die Soll-Kerntemperatur des Garguts, aufgeheizten Garraum gebracht oder der Garraum kurzzeitig, insbesondere auf die Soll-Kerntemperatur des Garguts, in Gegenwart desselben aufgeheizt wird, wobei man anschließend die Garraumtemperatur kontrolliert in Abhängigkeit vom Anstieg der Kerntemperatur des Garguts absenkt, bis eine vorgegebene Differenz zwischen Garraumtemperatur und Kerntemperatur erreicht ist, und wobei man im Folgenden die Garraumtemperatur kontinuierlich oder schrittweise auf die Soll-Kerntemperatur unter Aufrechterhaltung eines vorgegebenen Temperaturabstandes zwischen der Garraumtemperatur und der Kemtemperatur des Garguts erhöht.
摘要:
A method of anti-freezing protection of a fluid pipe, comprising forming a valve assembly (1) connecting, in mutual fluid communication, a thermostatic anti-freezing valve (2) responsive to a fluid temperature of a fluid in contact with the anti-freezing valve (2) itself, a thermostatic valve (3) responsive to an ambient temperature outside the valve assembly (1), making in the valve assembly (1) an inlet opening (5), a discharge opening (6) in communication with the inlet opening (5), and a first and only fluid communication (8) between the inlet opening (5) and the discharge opening (6), connecting the inlet opening (5) of the valve assembly (1) to the fluid pipe so that a fluid from the fluid pipe enters the valve assembly (1), using the anti-freezing valve (2) to open and close the discharge opening (6) automatically depending on the fluid temperature, using the thermostatic valve (3) to automatically open and close, depending on the ambient temperature, the first and only fluid communication (8) between the inlet opening (5) and the discharge opening (6), using a knob (21) of the thermostatic valve (3) to manually close and/or open the first fluid communication (8), regardless of the ambient temperature.

A heating/cooling system pre-setting arrangement (1) is provided, the pre-setting arrangement (1) comprising a housing (2) and presetting means (11, 12) defining a maximum flow through the valve arrangement (1) at a given pressure, wherein the presetting means comprise a presetting element (11) actuatable by means of a setting ring (6), wherein the setting ring (6) comprises a first geometry (7) and the housing (2) comprises a second geometry (8), the first geometry (7) and the second geometry (8) preventing rotation of the setting ring (6) when they are in engagement. Actuation of such a presetting arrangement (1) should be comfortable. To this end holding means (14, 15) are provided holding the setting ring (6) in a position in which the first geometry (7) is out of engagement of the second geometry (8).
摘要:
A gas powered soldering tool (1) comprising a main body member (4) terminating in a soldering tip portion (8) has a combustion chamber (10) located therein. A gas catalytic combustion element (12) is located in the combustion chamber (10), and fuel gas is delivered into the combustion chamber (10) from a jet nozzle (15) and an air mixing venturi bore (17). A temperature responsive controller (28) for controlling the fuel gas supply to the jet nozzle (15) comprises a valve (39) having a valving member (58) which is operable by a permanent magnet (63) slidably located in a bore (64). A first member (70) of thermomagnetic material the Curie point of which is substantially similar to the temperature at which the main body member (4) is to be controlled is located at one end of the bore (64). The magnetic attraction between the first member (70) and the permanent magnet (63) is greater than the magnetic attraction between a second member (71) in the bore (64) and the permanent magnet (63) when the first member (70) is magnetic, thereby maintaining the valve (39) open, and vice versa when the first member (70) becomes non-magnetic for closing the valve (39).
