Title: Continuous fabric wet treatment - with intermediate stage to intensify effect of treatment medium without increasing working space
Inventor: SCHUIERER MANFRED
IPC: D06B3/16
Filed: 1978-05-30
Abstract: In applying a wet treatment process to piece goods, there is an intermediate treatment zone between the two main treatment and dwell zones, for a treatment agent to act on the fabric. Specifically as the fabric is continuously fed into the first treatment/dwell zone, and similarly drawn out of the second treatment/dwell zones, the rate of fabric travel is increased in the intermediate zone, of the order of 3-10 times the fabric's entry and exit speeds in a forwards and backwards movement, in the vertical plane. By using a high relative movement between the fabric and the medium, the intensity of the treatment process is increased, without requiring additional space.

Patent DE-2835749-A1 (DE)
Inventor: VOEGELI ERNST F DIPL ING
IPC: F16K31/06
Filed: 1978-08-16
Abstract: In known solenoid valves, the magnet armature space is identical with or freely connected to the pilot control space. It is thus a relatively large space protruding from the valve which takes part in thermodynamic processes and consequently, when there are temperature differences between the fluid and the wall, evaporation and condensation processes occur in the entire space and these can impair the rapid functioning of the valve. In the solenoid valve according to the invention, these disadvantages are avoided because the solenoid armature space (25) is hydraulically separated from the pilot control space (17) and is connected directly to the inlet branch (2) and undergoes no change in volume when the spindle (8) is actuated. To relieve the spindle (8) of force, a longitudinal bore (18) is provided in the latter. These measures also improve the dynamic switching behaviour and lower switching forces are required. <IMAGE>
