Abstract: The invention relates to a process for operating a steam generating system, in particular in a fossil-fuel fired power station, e.g. in a gas and steam turbine system, in which steam is generated from water by indirect heat exchange with hot smoke gas (RG), condensed water (K) first being preheated and the preheated water (W) subsequently being evaporated under great pressure. The process is characterised in that, in the partial-load range of the system, the preheated water (W) under great pressure is cooled by heat exchange with at least a partial flow (t1) of the condensed water (K). Furthermore, the invention relates to a system with a steam generator (1), one heating surface of which is a condensation preheater (3). The system also comprises a heat exchanger (40) which is connected downstream of the condensation preheater (3) on the primary side and is connected upstream of the condensation preheater (3) on the secondary side.

Abstract: A miter saw includes a support mechanism (16) for supporting a miter saw unit relative to a base (2) in such a manner that the miter saw unit is both vertically and laterally pivotable. A position determining mechanism serves to selectively determine the position of the saw unit (21) at any of positions including a vertical position where a saw blade is positioned substantially vertically relative to the base (2), and leftward and rightward pivoted positions where the saw blade is inclined laterally leftwardly and laterally rightwardly from the vertical position by a predetermined angle, respectively. The position determining mechanism includes movable side stopper members (52, 59) and fixed side stopper members (51, 52) on which the movable side stopper members abut, respectively. The movable side stopper members (53, 59) are mounted on a movable member (15) which pivots laterally with the miter saw unit. The fixed side stopper members (51, 52) are mounted on a fixed member (16) which is non-laterally pivotally movably mounted on the base (2). The movable side stopper members (53 or 59) abut on their corresponding fixed side stopper members (51 or 52) when the miter saw unit is at the vertical position and at the leftward and rightward pivoted positions, respectively.

Abstract: A known three-phrase rectifier (A) has at least one sub-unit having a first three-phase system and a second three-phase system in parallel line branches (1a, 1b, 1c and 3a, 3b, 3c), which each contain a six-pulse bridge circuit (B) with controllable converter valves. A device produces a phase shift in the voltages of the first three-phase system by 30@ with respect to those of the second three-phase system. Only a single regulator is required to regulate the output voltage of the three-phase rectifier (A). The regulator periodically emits a delay angle which is intended for driving the converter valves of a specific six-pulse bridge circuit (B). The delay angles for the other six-pulse bridge circuits (B) are calculated from the delay angle of the regulator, taking into account the currents flowing out of the six-pulse bridge circuits (i1, i2). <IMAGE>

Abstract: A claw lock mechanism for a railway turnout comprises a pair of stock rail brackets (1), each of which is located on a stock rail (2) at a position in the region of the toe of an adjacent tongue rail, and each of which has an open-ended passage extending transversely beneath the stock rail (2), a drive bar (20) which extends through and beyond the passage of each bracket (1) for moving the tongue rails between each operating position, and a pair of claw arms (22) each of which extends through the passage of one of the brackets (1). One end of each arm (22) is pivotally fixed (at least indirectly) to one of the tongue rails and the other end thereof has a claw (23) which can engage a notch (34) in the drive bar (20) to allow both the drive bar and the claw arm to slide through the passage until the associated tongue rail contacts the stock rail (2). Further movement of the drive bar through the passage forces the claw (23) out of the notch (34) and locks the arm (22) in the passage thereby preventing inadvertent movement of the tongue rail away from the stock rail. According to the invention each stock rail bracket (1) is immovably secured to its associated stock rail and at least a major part of the peripheral surface of each transversely extending passage is defined by a carriage (24) that is located within the bracket (1) and can be moved at least to a limited extent in a direction lengthwise with respect to the stock rail (2) directly by the drive rod (20) or the claw arm (22) bearing on a surface of the carriage (24) defining the passage. This form of mechanism is relatively simple to manufacture and is reliable.

Abstract: The invention concerns a method and a device in crawling operation of a press felt (H) in a paper machine. The press felt (H) has been passed as a closed felt loop through the nip (N) placed between the centre roll (K) and the press roll (T) in the press of the paper machine, the felt (H) being driven, during the running proper of the paper machine, by means of the nip drive (N) between the centre roll (K) and the press roll (T) of the press. When the paper machine is not being run and the nip (N) between the centre roll (K) and the press roll (T) in the paper machine is open, the felt is moved, so as to moisten the new felt (H), by means of the crawling drive by rotating the drive roll (10). The axle (10a) of the drive roll (10) is permanently connected with a drive rim (20). During crawling operation, the drive wheel (19;27a,27b...) of a hydraulic device (14,17;26a,26b...) is brought into engagement with the drive rim (20), and, when the crawling drive of the felt is not in operation, the drive roll (10) is switched to the free revolving position by shifting the drive wheel (19;27a,27b...) of the hydraulic device (14,17;26a,26b...), which drive wheel is operationally connected with the drive rim (20), apart from the drive rim (20).
