Title: Seat valve with integral valve seat got hot water and steam systems
IPC: F16K27/02
Filed: 1998-01-23
Abstract: The valve, intended particularly for systems carrying hot water or steam, has a valve casing (2) which is made in one piece from a material with high Brinell hardness.  The valve seat is produced from the cast blank by machining, so that there is no transition of valve seat material to valve casing material.  The hardness of the casing material is greater than that of the valve closing member (15) fitted in it, so that the valve seat suffers little or no wear.

Abstract: The invention relates to a program flow method in a program component system which has a running time system (14) and a number of components (20, 20', ...). The inventive method comprises a data acquisition of data pertaining to a second component (20') in the first component (20) independent of programming-defined interfaces in the second component (20'), said data acquisition being conveyed by the running time system (14). The inventive method also comprises a data acquisition of data pertaining to the first component (20) in the second component (20') independent of programming-defined interfaces in the second component (20'). In a method for expanding a program component system around an additional component, the invention provides that docking points are to be searched for the additional component, and the respective components (20, 20',...) of the program component system in which at least one docking point has been found are to be changed by registering call information on each docking point which has been found.

Title: Machine for drying and fixing fabric piecegoods
Inventor: FREIBERG HELGE
IPC: F26B13/02
Filed: 1998-02-21
Abstract: The assembly for drying and/or fixing textile piecegoods has a return flow structure for the gas under pressure (17) after it has been blown at the fabric (1) in the symmetrical treatment field (5). The used gas under suction (18) has a return path through the backflow channels in the backflow zone, directly at the rear side of the blower box (32). It flows along the center line (4) in two divided flow paths (18a, 18b) on both longitudinal edges of the treatment field (5). The divided return flow channels (18a, 18b) come together in front of the entry side of the fan housing (21), or at the latest in the fan (13).  A flow guide (31) divides the return flow path (18), with its main section (33) as a guide surface parallel to the rear side of the blower housing (32) or the treatment plane (E). The main section (33) of the flow guide is symmetrical to the center line (4) of the treatment field (5). The main flow guide edge (37) has a deflection surface (34) extending to the point (19) where the part flows reunite. The main flow guide surface (33) extends max. over the machine width (B). A sieve mesh (19), to trap lint, is at the junction of the divided part flows, in front of the suction side (21) of the fan (13). The suction forces in the part flow channels (18a, 18b), exerted by the suction side (21) of the fan (13), are set at equal levels through the geometry of the flow paths. The part flow channels (18a, 18b) are split from the lower and upper blower boxes (8, 9), with flow guides (31) at the rear sides (32) of both blower boxes (8, 9). One part flow channel (18a) has at least one lateral suction connection (44). The machine cover (47) acts as a flow guide (31) at the rear side (32) of the blower box, on the opposite side of the treatment plane (E) to the fan (13).
