1. A fastener nut for hydroformed parts comprising a nut body and a flat-sided locking ring carried by said nut body, said nut body adapted to receive a threaded fastener and having an integral flat-sided punch adapted to pierce and form an inwardly projecting flat-sided retention collar in a hydroformed part while the part remains in a die cavity and under internal hydroforming pressure, said nut body adapted to position said locking ring within said retention collar while positioning said punch beyond said retention collar to thereby prevent turning of said locking ring relative to said retention collar while allowing turning of said nut body relative to said locking ring, and said nut body and said locking ring adapted so that said locking ring on partial turning less than a complete revolution of said nut body with respect to said locking ring causes said locking ring to structurally interlock in a fully assembled position with said retention collar and thereby attach said nut to the hydroformed part while the part remains in the die cavity.
2. A fastener nut as described in claim 1 wherein said locking ring has integral fingers adapted to co-operate with said retention collar to prevent said locking ring from turning with respect to said retention collar, and said nut body is adapted to deflect said fingers outwardly from said nut body into locking engagement with said retention collar on partial turning of said nut body.
3. A fastener nut as described in claim 1 wherein said nut body has a recessed portion defined in part by a cam surface, said locking ring has a ring-shaped body with depending fingers and is received in said recessed portion with said fingers against said cam surface, and said cam surface adapted to initially position said fingers in alignment with the sides of said punch during said piercing and retention collar forming operations by said punch and then on partial turning of said nut body deflect said fingers outwardly from said nut body with rotary cam action and into structural locking engagement with said retention collar.
4. A fastener nut as described in claim 1 wherein said punch is at one end of said nut body and an opposite end of said nut body has a drive socket adapted to be located flush with an outer surface of the hydroformed part.
5. A fastener nut as described in claim 3 wherein said ring-shaped body of said locking ring is split to allow said locking ring to be expanded for reception in said recessed portion of said nut body.
6. A fastener nut as described in claim 3 wherein said punch is adapted to pierce a slug that is integral with the retention collar.
7. A fastener nut as described in claim 3 wherein said punch and said cam surface have a polygonal shape.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for providing price information to subscribers of a digital mobile communications network, in which the subscriber receives actual connection costs to be expected in response to dialing a call number and, on dialing a call number, the actual connection costs to be expected is displayed directly on a subscriber’s mobile radio terminal display using a high-priority short message service (SMS), characterized in that the price information is provided only when the actual price is not the same as the price to be expected on the basis of a dialed call number and the dialed call number is a mobile number portability (MNP) call number or a special call number.
2. The method as claimed in claim 1, wherein the subscriber receives the actual connection costs while setting up the desired connection.
3. The method as claimed in claim 1, wherein the subscriber receives the actual connection costs before setting up the desired connection.
4. The method as claimed in claim 1, wherein the subscriber allows the connection to be set up by confirmation of the transmitted actual connection costs.
5. A system for providing price information to subscribers of a digital mobile communications network, in which the subscriber receives from a communications point actual connection costs to be expected in response to dialing a call number and, on dialing a call number, the actual connection costs to be expected is displayed directly on a subscriber’s mobile radio terminal display using a high-priority short message service (SMS), characterized in that the price information is provided only when the actual price is not the same as the price to be expected on the basis of a dialed call number and the dialed call number is a mobile number portability (MNP) call number or a special call number.
6. The system as claimed in claim 5 wherein the subscriber receives the actual connection costs while setting up the desired connection.
7. The system as claimed in claim 5 wherein the subscriber receives the actual connection costs before setting up the desired connection.
8. The system as claimed in claim 5 wherein the subscriber allows the connection to be set up by confirmation of the transmitted actual connection costs.
