Patent CA-2449901-A1 (CA)
Title: Safety cutting apparatus
Inventor: VOTOLATO EARL
IPC: B26B29/02
Filed: 2003-11-19
Abstract: A cutting apparatus has been produced that eliminates the common occurrence of raw razor blades contaminating everything from food and food products to garbage cans to shelves in retail stores. Furthermore, the cutting apparatus comprises a guard assembly that, when activated, opens the blade cover and allows only one cut to be made with the exposed blade before the unidirectionally-locking blade cover snaps back over the exposed blade, thus preventing laceration-related accidents. In addition, if the operator continues to activate the guard assembly (squeezing, pulling and/or depressing the trigger and/or releasing the trigger and continuing to hold it in the released position during and after the cut has been made) after one cut has been made with the exposed blade, the unidirectionally-locking blade cover will still snap back over the exposed blade, despite the position.of the trigger. Once the blade cover snaps back over the exposed blade, the locking device is activated and acts to hold the blade cover securely over the blade until the blade assembly is further activated by releasing the trigger from the depressed position and depressing, releasing, squeezing or pulling the trigger once again.

Patent CA-2485786-A1 (CA)
Inventor: CASLAVSKY KAREL
IPC: F24F13/14
Filed: 2004-10-25
Abstract: A novel damper system for controlling airflow through a plenum provides an effective seal between a rotatable damper door and the plenum to substantially inhibit airflow through the plenum without requiring additional sealing materials such as rubber or foam. When the damper door is in the closed position, an upstanding rib on each of the upper and lower portions of the damper door engage a complementary groove in a respective sealing member on the interior of the plenum against which the damper door faces abut.  The engagement of the ribs in the groove provides a seal comprising three surface-to-surface interfaces. The sealing members are relatively small, compared to the size of the plenum, and thus present little impediment to airflow through the plenum when the damper door is rotated to an open position.
