Abstract: A gas and steam-turbine plant includes a waste-heat steam generator connected downstream of a gas turbine on the flue-gas side. The waste-heat steam generator has heating areas connected in a water/steam circuit of a steam turbine. A heat exchanger is provided for cooling a coolant of the gas turbine in order to ensure reliable cooling of the gas turbine even under varied operating conditions. The heat exchanger has a secondary side connected in a second water/steam circuit. The second water/steam circuit is connected to the water/steam circuit of the steam turbine in such a way that it can be shut off. A method is also provided for cooling a coolant of a gas turbine of a gas and steam-turbine plant.

Abstract: A gas and steam-turbine plant having a heat-recovery steam generator which is connected downstream of a gas turbine on a flue-gas side is described. The heat-recovery steam generator has heating surfaces connected in a water/steam circuit of a steam turbine. Cooled air for cooling the blades can be directed via an evaporator to the gas turbine. The evaporator is connected on a secondary side to the water/steam circuit and opens on an outlet side into a steam-collecting chamber. The steam-collecting chamber is connected to a water/steam drum via feed pipes connected in parallel on a steam side. The intention is to ensure that, during the transport of the water/steam mixture from the evaporator to the water/steam drum, a separation of the two-phase mixture is reliably prevented. Therefore, the steam-collecting chamber has a number of sub-chambers, which are connected to one another and in each case assigned to a feed pipe.

Abstract: A conveyor system includes a back arm pivotal about a first vertical axis; a discharge arm pivotal about a horizontal axis and about the first vertical axis; a discharge belt mounted on the discharge arm and extending rearward, beyond the first vertical axis, to the back arm; and a connecting bridge pivotal about second and third vertical axes, and supported on a separate, movable device so as to be longitudinally displaceable. The connecting bridge is articulated to a component of the conveyor system above the back arm. The second vertical axis is spaced from the first vertical axis at a predetermined distance and disposed diametrally opposite a discharge end of the discharge belt with respect to the first vertical axis. There is further provided a connecting belt mounted on the connecting bridge and feeding the discharge belt.

Abstract: The device for embossing Braille code characters on a movable paper web includes a set of plungers supported for reciprocating movement against a stationary matrix for embossing dots in respective lines; a continuously reciprocating beam is arranged below the lower ends of all plungers and each plunger cooperates with an actuation device such as a solenoid which selectively deviates the lower end of the plunger out of engagement or into engagement with the impact surface of the reciprocating beam.
