Title: Cylindrical lock assembly
Inventor: SLUSARSKI RONALD S
IPC: E05B63/16
Filed: 1994-02-22
Abstract: ABSTRACT         A cylindrical lockset having a locking mechanism which normally secures an outside operator in a fixed position so that the outside operator cannot be operated to open an associated door. A key operated cylinder lock associated with the outside operator must be operated to unlock the locking mechanism so that the door can be opened from the outside.  When the locking mechanism is in its unlocked condition the outside operator may be operated to open the door but the key remains trapped in the lock.  Return of the key to its shed position for removal from the lock returns the locking mechanism to its locked condition thereby locking the outside operator.  An inside operator is at all times operable to open the door.

Title: Method for treating pulp
Inventor: EKHOLM ROLF
IPC: D21C9/02
Filed: 1993-02-16
Abstract: The present invention provides a method for washing a fibre suspension to alter its liquid content. The method includes the first step of feeding the fibre suspension into an undivided annular displacement space that rotates around an axis of symmetry, the displacement space having an outer limiting, permeable surface. The method includes the second step of supplying, with pressure external to the displacement space, a fluid through the permeable outer surface of the displacement space. The method includes the third step of rotating the displacement space with a rotational speed which is sufficient to establish, by centripetal acceleration of the fibre suspension, a fibre layer which is disposed between the fluid supplied through the permeable outer surface of the displacement space and a remaining part of the fibre suspension, the fibre layer providing a pressure against the outer limiting surface of the displacement space which at least essentially balances a pressure from the fluid. The method includes the final step of moving the fibre suspension and the fluid through the displacement space and discharging the fibre suspension and the fluid from the displacement space.

Title: Flywheel driven fastener driving tool and drive unit
Inventor: CRUTCHER JOHN P
IPC: B25C5/15
Filed: 1995-01-04
Abstract: A power tool has a flywheel for driving a working member such as the driver of a fastener tool. A motor mounted at a rear end of a tool handle drives the flywheel mounted in a tool housing at the forward end of the handle. A cable is secured to a drum and to the working member.          A clutch selectively couples the flywheel to the drum to wind up the cable and drive the working member forcefully. A return cable is wound on the driver drum against a spring bias to rewind the drum, unwind the cable and return the working member to its prior status when the clutch decouples the flywheel from the drum. When the flywheel is coupled to the drum, the motor speed and flywheel speed is reduced. An electronic control operates the motor to recapture the initial speed within 500 milliseconds of the speed reduction. The electronic control includes a phase-locked loop velocity control.
