Title: Valve actuator external spur gear drive - includes pinion driving spindle through idlers mounted close to spindle
Inventor: SAENGER BERNHARD
IPC: F16H1/20
Filed: 1977-03-19
Abstract: The drive for a remote operated valve actuator includes a spur gear train. The idler and/or reduction gears (21-26) are mounted between the drive pinion (12) and the gear wheel (32) which is mounted on the spindle (31) to be driven. The idler/reduction gears are mounted on an arc or spiral (K) around the spindle.

Title: Adsorber for air purification - having run=off line for condensate formed during desorption with filter, which has purge valve to allow run=off of sludge
IPC: B01D53/04
Filed: 1978-03-06
Abstract: Condensate formed in an adsorber during desorption cycle is run off through a line containing a sludge filter. This filter has a purge valve which can be opened at time intervals or if the condensate level exceeds a certain level The adsorber is a vessel with gas inlet at the top and gas outlet at the bottom. The outlet consists of a stand pipe which creates a volume of such capacity that it exceeds the quantity of water needed for the purge operation. The gas outlet has a valve plate on the end of the stand pipe operated by a piston shaft which can move up and down. For use with adsorbers e.g. for removing solvents from air streams. When an adsorber is charged with fresh adsorbant, a considerable amount of sludge is washed out during the early desorption cycles. This tends to block condensate run-off lines and filters. The system described gives improved run-off.
