Title: Method for foiling cellular telephone cloning
Inventor: ROSA STEPHEN P
IPC: H04W12/06
Filed: 1996-08-22
Abstract: A method for foiling cellular telephone cloning by verifying subscribers of a cellular communications network is accomplished by having each subscriber provide a local telephone number, typically not their own, to the cellular telephone company and long distance carrier for each cellular telephone they own in order to verify legitimate subscribers. Shortly after power-up of the cellular telephone, a subscriber either invokes an automatic dialer or manually dials the verification telephone number. A computer in the cellular network receives the subscriber's first call after power-up and verifies the dialed telephone number against the verification telephone number stored in a database corresponding to the electronic serial number of that cellular telephone. In response to a match, the cellular network transmits a single ring to the subscriber telephone as confirmation of a validation; otherwise a message requesting enablement of the cellular telephone is transmitted to the subscriber telephone.

Patent CA-2258057-A1 (CA)
Title: Soffit mounted dryer vent
Inventor: BOS JIM
IPC: F24F13/06
Filed: 1998-12-30
Abstract: A new Soffit Mounted Dryer Vent for offering a non-maintenance exhaust vent system for a clothes dryer vent that terminates in a soffit of a roof overhang. The inventive device includes a flange, a dryer hose adapter ring, an outlet fitting, and a vent flapper.     The flange has an air passage, an upper surface, and a lower surface.     The air passage allows exhaust air to pass through the flange from the dryer hose adapter ring to the outlet fitting. The dryer hose adapter ring is symmetrically mated to the upper surface of the flange. The dryer hose adapter ring has an outer wall diameter of substantially the same dimensions as the clothes dryer vent hose thereby allowing the clothes dry vent hose to matingly slip over the dryer hose adapter ring.     The outlet fitting, having an outlet opening, is adjoiningly mated to the lower surface of the flange. The vent flapper is pivotally attached to the outlet fitting at the outlet opening.      In use, the clothes dryer vent hose is slipped over the dryer hose adapter ring. The flange is attached to a soffit of a roof overhang by a fastener, such as a screw or a nail. Exhaust air from the clothes dryer vent hose flows through the dryer hose adapter ring, through the air passage of the flange, and through the outlet fitting.    The force of flowing exhaust air causes the vent flapper to pivot outward allowing exhaust air to exit through the outlet opening of the outlet fitting. When no exhaust air is flowing, a flapper stop prevents the vent flapper from pivotally rotating into the outlet fitting beyond a substantially vertical plane.

Patent CA-2260539-A1 (CA)
Title: Tee nut
Inventor: NAGAYAMA YUTAKA
IPC: F16B37/06
Filed: 1999-01-28
Abstract: A tee nut includes a shaft portion and a flange portion outwardly extending from a first end of the shaft portion. The shaft portion includes a step around the periphery thereof at an intermediate position of its axial length, a forward end side cylindrical portion having a hollow cylindrical shape located between the second end of the shaft portion and the step, and a base end side enlarged cylindrical portion having inner and outer diameters larger than those of the forward end side cylindrical portion. The forward end side cylindrical portion includes a predeterminate caulked part formed over a prescribed length from the second end and a female screw forming part between the step than the predeterminate caulked part. According to this structure, the length of the forward end side hollow cylindrical portion including the female screw forming part can be relatively reduced, and hence the length of the female screw forming part is not increased beyond necessity but can be set at the minimum necessary value agreeing with a standard such as ISO standard even if the shaft portion has a large length. Thus, no additional working is required in a threading step with a tap and the productivity of the tee nut can be improved.
