Patent CH-680153-A5 (CH)
Title: Simultaneous driving of three parallel shafts
Inventor: MAINEULT JEAN
IPC: H01H19/64
Filed: 1989-08-14
Abstract: The shafts of a three-phase circuit-breaker are parallel and situated in the same plane (1, 2, 3).  A fourth driving shaft (4) is parallel to their direction, while a triangular flat piece (5) is placed in a plane normal to that direction.  Handles with associated levers (11, 21, 31) are wedged on the respective shafts using pins (12, 22, 32). A similar lever (40) is provided on the opposite face of the triangular piece, for the driving shaft.  The four levers are parallel and orientated along the same direction. The movement of the driving shaft is transmitted to the other shafts via the triangular piece that executes a rotation in its own plane.

Title: Centrifugally sepg. entrained particles in a flat casing - with twin internal flow routes for divided gas stream
Inventor: SAURER GERHARD
IPC: B01D45/16
Filed: 1985-10-16
Abstract: Slot in the flanged end of a flat parallelepipedal casing receives a stream of gas contg. liq. or solid particles. The gas is accelerated between converging side walls, before encountering a projection dividing the stream into two parts. Each stream is diverted round a curved wall against which the particles mass before passing through a narrow gap into a chamber, while the gas itself flows in a broader sweep towards an exit end of the casing. Particles from the chambers are removed via a common outlet pipe. The positions and angles of the curved walls may be varied by externally accessible screws for adaptation to nature of entrained particles.  Units may be assembled as modules. Incoming gas may be sprayed with liq. ADVANTAGE - Main internal components may be sections cut from continuous extrusions, thus reducing mfg. costs.
