Filed: 1993-04-05
Abstract: A crimping tool includes first and second jaws (1, 2) which are journalled at a first pivot point (5) for pivotal movement relative to one another. A forward end of a first handle (6) is rigidly connected to the first jaw (1), while a forward end of a second handle (7) is pivotally connected to the second jaw (2) at a second pivot point (8). A linkage construction (9) extends obliquely rearwards from a third pivot point (10) located on the second handle (7) rearwardly of the second pivot point (8), up to a fourth pivot point (11) on the first handle (6). The distance (D) between the first and the second pivot points (5, 8) is 0.30-0.35 times the distance (A) between the first and the fourth pivot points (5, 11), the distance (C) between the second and the third pivot points (8, 10) is 0.20-0.25 times the distance (A) between the first and the fourth pivot points (5, 11), and the distance (B) between the third and the fourth pivot points (10, 11) is 0.62-0.66 times the distance (A) between the first and the fourth pivot points (5, 11). In the closed position of the jaws (1, 2) a plane (E) which contains the second and the third pivot points (8, 10) defines an angle (.alpha.) of 165-180· with a plane (F) which contains the third and the fourth pivot points (10, 11), with the apex of the angle facing away from the first handle (6).

Patent CA-2143129-A1 (CA)
Inventor: CAUSA ALFREDO G
IPC: B60C9/18
Filed: 1995-02-22
Abstract: Partially oriented yarns (POY), when processed into short fibers and used as a fiber reinforcement in an elastomer, have been found to demonstrate reduced crack propagation in the elastomer.  POY reinforced elastomers can be used in tires to replace cord reinforced components, and for example, can be used in the tread base of a tire, obviating the need for an overlay ply. In one embodiment it has been found that the properties of a fiber reinforced elastomer can be optimized by using a mixture of partially oriented fibers and fibrillated pulp fibers, such as pulped high modulus rigid rod liquid crystalline fibers, as the fiber reinforcement.

Inventor: KLEM RUSSELL D
IPC: H04M3/00
Filed: 1996-02-29
Abstract: The system of the invention provides a method for handling interswitch handovers in a personal communication services (PCS) system. Specifically, the method of the invention designates the original switching system that hosts the radio port control unit (RPCU) that first serves the call as the anchor switch. The anchor switch maintains this status for the duration of the call and is always responsible for setting up the three-way connection to effectuate the interswitch handover regardless of how many additional new switching systems host RPCUs that serve the call as the mobile station moves through the system. The additional new switching systems hosting the new RPCUs always communicate with the anchor switch and the call is always routed from the anchor switch directly to the switching system hosting the RPCU serving the mobile station. Intermediate switches are dropped from the connection when the mobile station exits the areas they serve thereby eliminating the need to maintain connections through prior switching systems.
