Patent NO-165986-C (NO)
Inventor: DUMICAN BARRY LEE
IPC: A61F2/06
Filed: 1986-04-24
Abstract: The invention involves the use of absorbable or absorb- able/nonabsorbable components to fabricate textile vascular grafts of all sizes and specifically for repair of the peripheral vascular system and for coronary bypass use. The bioabsorbable components of the graft fosters increased tissue ingrowth into the graft as compared to conventional 100% nonabsorbable grafts. Increased tissue ingrowth leads to greater patency through formation of a vascularized neointima and less tendency to be aneurysmal through formation of a suitable adventitia.

Title: "automatic safety device for fire arms"
Inventor: BERETTA PIER GIUSEPPE
IPC: F41A3/72
Filed: 1990-01-03
Granted: 2000-12-05
Abstract: The invention relates to an automatic safety device for fire arms, in particular for automatic guns to be operated starting from their open-bolt position. A movable slider (12) and a rocking catch lever (19), both assembled to a support on the bolt (11), cooperate an order to allow the lever to engage in a toothed section (15) on the breech (10) and thus prevent the bolt from moving forwards in case of a faulty move, of a release or missed catch during its manual cocking and to maintain the device out of action while the arm is operated wither automatically or manually. Owing to this structure the possibility of uncontrolled or accidental shots is actually eliminated.

Title: Zero chuck vehicle seat latching mechanism
Inventor: PREMJI GULAM
IPC: B60N2/20
Filed: 1993-02-10
Granted: 1998-02-17
Abstract: A seatback latching mechanism for use in a vehicle seat assembly having a seatback member pivotally tiltable over a seat cushion member is disclosed. The latching mechanism is used to secure the seatback member against pivotal movement in a forward angular direction relative to the seat cushion member, when the seatback member in its relatively upright angular orientation, by latching first and second hinged members. There are first and second stop means securely affixed to the first hinged member, first and second abutment means securely affixed to the second hinged member, and a selectively positionable latch member rotatably mounted on the first hinged members for movement between a latching position and an unlatching position. When the selectively positionable latch member is in the latching position, the first stop means and the first abutment means are in intimate contact with one another so as to preclude unwanted pivotal movement of the first and second hinged members with respect to each other in the rearward angular direction. Further, a first contact surface on the selectively positionable latch member and the second abutment means are in intimate contact with one another, and the selectively positionable latch member is physically interposed between the second stop means and the second abutment means so as to preclude unwanted pivotal movement of the first and second hinged members with respect to each other in the forward angular direction. Resultingly, there is substantially no radial lost motion between the first hinged member and the second hinged member in the first relative angular orientation.
