Abstract: In a stop valve (1) in which the maximum percentage opening is adjustable, the restriction of the valve is carried out by adjustment of a valve rod (3), on which a valve disc (4) is fixed, which cooperates with a valve seat (5) within the valve body (2) of the stop valve. The valve rod (3) consists of two axially movable parts (6, 7) which are adjustable in relation to each other by means of a driver connection, the most inner part (7) supporting the valve disc (4). In order to facilitate the adjustment and simplify the design the axially extreme valve rod part (6) is cylindric and has external threads (8), which cooperate with threads which are fixed in relation to the valve body. When said valve rod part (6) is rotated it moves in axial direction to or away from said valve seat (5). The axially inner valve rod part (7) is inserted in the cylindric extreme valve rod part (6) and the driver connection consists of a friction arrested screw connection (9) connecting the two valve rod parts.

Abstract: The present invention relates to the measuring of phase currents in an inverter, where by pulse width modulation controlled semiconductor switches invert a direct voltage from an intermediate circuit into a three-phase alternating voltage. The phase currents are measured by measuring the intermediate circuit current when an active switch state creates an unambiguous relation between the intermediate circuit current and a phase current. Time shifts in the phase current measuring can be avoided by measuring the value id of the intermediate circuit current in two separate settings ( u 1, u 1; u 6, u 6) of the same active switch state ( u 1; u 6) in a modulation period (TSW) and by creating a resulting mean value of the measured values. The mean values can be related in time to the centre of the modulation period, and the third phase current at the same time can be calculated, because the sum of the phase currents is equal to zero.

Abstract: A diaphragm-controlled differential-pressure valve has a valve housing (1) which is constructed in one piece with the lower part (5) of a diaphragm capsule (6). The associated cover (9) carries a spring housing (20) accommodating the set-point spring (18). This produces a valve having a very small overall height.

Abstract: A method for defrosting a refrigeration system (38) makes provison for partial defrosting of the cooling surface (39) to be carried out at relatively short intervals, and for full defrosting to be carried out at longer intervals. To that end an associated control unit (41) has four timers (44 to 47) which determine the switching on and switching off times of the defrosting processes. In this manner the interval between successive full defrostings can be considerably increased.

Abstract: In cold flow processing of metals, especially steel, coatings of transition metal halogenides, especially FeCl3, have proved suitable because they efficiently counteract cold welding problems. The coatings may be applied in the form of a melt or a saturated or diluted, aqueous solution of the transition metal halogenide. If a melt is used, it may be mixed with one or more common solid lubricants such as MoS2, graphite, or the like.

Abstract: A control arrangement for cooling of apparatus comprising a compressor (1), a condenser (2) and at least one branch (3) with an expansion valve (4) and an evaporator (5) in series, contains a controller (6), a superheat temperature measuring device (8) and an ambient temperature sensor (7). The controller (6) controls the expansion valve (4) for maintaining the superheat temperature substantially at the desired value. The flow of coolant to the evaporator (5) is controlled by the signal from the temperature sensor (7) for maintaining the ambient temperature constant. The controller (6) operates continuously and in two operating modes in which in the first mode the superheat temperature is controlled to the maximum admissible state of fill of liquid coolant in the evaporator (5), and is switchable to a second mode in which the state of fill of liquid coolant is controlled by the expansion valve (4).

Abstract: A control arrangement for the temperature of the water drawn from a water pipe (5) contains a heat exchanger (3) lying with its primary side in series with a flow-adjusting valve (4) in a heated water circuit (2), and with its secondary side in the water pipe (5), a temperature sensor (6) lying in the water pipe (5) downstream of the heat exchanger (3), which temperature sensor converts the measured temperature into a pressure acting on a closure member of the flow-adjusting valve (4) against the force of a spring bearing against the housing (16) of the flow-adjusting valve (4), and a measuring orifice (7) in the water pipe (5). The flow-adjusting valve (4) contains a diaphragm between two chambers (10, 11), of which one (10) is connected to the high pressure side of the measuring orifice (7) and the other (11) is connected to the low pressure side of the measuring orifice (7). The deflection of the diaphragm (9) caused by the differential pressure at the measuring orifice (7) acts against the pressure of the temperature sensor (6) on the closure member of the flow-adjusting valve (4). To provide an energy-saving control arrangement, the diaphragm is rigidly connected to the closure member of the flow-adjusting valve (4) in the closing direction thereof, and its deflection in the opening direction of the flow-adjusting valve (4) is continually correlated with the pressure difference at the measuring orifice (7) and the difference between the spring force and the pressure force of the temperature sensor.

Abstract: A method is disclosed for calibrating an analysis system having a membrane (2), the outside of which is in contact with a medium (3) to be analyzed, in order to detect a concentration of a species there, and a corresponding analysis system. In this connection it is desirable to be able to perform a calibration in situ. In this calibration, a first fluid (9) of a predetermined first concentration of the species is conveyed along the inside of the membrane (2), at least a second fluid (12) of a predetermined second concentration which differs from the first concentration is likewise conveyed past the inside of the membrane and the concentrations of the two fluids (9, 12) after passing the inside of the membrane are recorded. From these concentrations, parameters for a correlation between the concentration on the outside of the membrane (2) and a measurement signal are ascertained.
