Abstract: Systems and methods are provided for automatic notifications of expired subscriptions. In various embodiments, a network function can request a subscription from a Unified Data Repository (UDR). The request for the subscription can include a request for a notification when the subscription expires or at a time prior to the expiration of the subscription. When the subscription expires or at the time prior to the expiration of the subscription, the UDR can provide a notification that the subscription has expired or is about to expire. Based on the notification, the network function can request to re-subscribe or request a new subscription from the UDR.

Abstract: It is known to utilize a screed extension apparatus along the front surface of a mold board in a machine for spreading pulverulent material such as a paving machine. Such a screed extension apparatus normally includes a strike-off plate and means for mounting and moving this plate between a retracted position generally in front of the mold board and an extended position in which the strike-off plate extends from an end of the mold board so as to serve as an extension of the mold board. Such a structure can be improved by utilizing two housings, the second of which fits around the first in such a manner that the second housing may be moved linearly with respect to the first but is restrained from any other type of relative movement with respect to the first housing. The first housing is secured in front of the front surface of the mold board well above the bottom of the mold board and adjacent to the end of the mold board. The second housing carries the strike-off plate.
