Patent CA-2112593-A1 (CA)
Inventor: RUMOCKI ANDRZEJ
IPC: C02F11/127
Filed: 1992-06-24
Abstract: In order to considerably reduce expenditures for the dewatering of sludges, particularly from sewage treatment facilities, and thereby perform the step from a sticky, wet solid to a flowable solid granulate practically without the re-admixture of material, it is proposed to employ a solid bowl sludge centrifuge as the dispersing member in a subsequently connected convection dryer for further dewatering of the wet solids particles that are ejected with a dry substance content of approximately 25-35 weight per,cent.  The wet solids particles that are ejected at high speed in the form of a film of particles from the outlet of the solid bowl sludge centrifuge are surrounded by the hot drying gas while still on their trajectory and are pre-dried to a dry substance content of approximately 65 weight percent (Figure 5).

Title: Pressure switch
Inventor: ELLETT JAMES RICHARD
IPC: H01H35/38
Filed: 1994-08-02
Abstract: A pressure switch has a housing with an interior bore extending from one end to the other. A rod slidable within the bore and operated by external fluid pressure extends between a piston at one end of the housing and a mechanically operated electrical switch at the other end of the housing. A spring is disposed about the rod between a first stop on the rod and a second stop on the housing. The spring provides resistance against movement of the rod under external pressure. The resistance of the spring to movement is adjusted by a sleeve engaging the spring, with the sleeve threaded into the bore of the housing for movement longitudinally within the housing. The sleeve includes  plural  radially  extending  slots  disposed around the sleeve. A port in the housing allows access to the sleeve and a cover is provided for the port. The cover includes a ring disposed around the housing and threaded onto the housing over the port.   The electrical switch is mounted on a block that has a central hold down screw passing through the switch mounting block and threaded longitudinally into the housing. A pair of jacking screws flank the central screw, are threaded into the housing and are received by screw receiving counterbores in the switch mounting block. Each of the jacking screws supports the switch mounting block in fixed relationship to the housing, with each of the screws being accessible from the second end of the housing through the screw receiving bores.
