Patent CA-2251725-A1 (CA)
Inventor: BASTIAENS WILLEM V
IPC: B42D5/00
Filed: 1997-03-13
Abstract: A sheet dispenser (10) including a housing (12), and a stack of dispensable sheets (14). A front wall of the housing has edges that define a slot through which an end portion of the top sheet on the stack projects. That front wall normally projects above the top surface of the stack of sheets (14) to position that end portion of the top sheet in a position projecting above an outer surface of the front wall where it can be easily grasped to withdraw the top sheet from the housing. At least a portion of the front wall is of flexible material so that it can be resiliently bent to lie along the top surface of the stack and thereby reduce the thickness of the dispenser (10) when, for example, it is positioned on one of the pages of a book, magazine, personal organiser or the like that is closed.

Title: A method and apparatus for locating a digital control channel in a radiocommunication system
Inventor: HENRY RAY
IPC: H04L29/02
Filed: 1994-11-01
Abstract: A method and system for locating control channels, particularly digital control channels are described. By grouping the channels which are candidates for carrying supervisory messages in blocks indicative of their relative likehood for being used as control channels, a mobile station can begin its search for a control channel with channels which are most likely to actually be control channels. Placing location information on other channels allows the mobile station to be redirected to a control channel when it reads one of these other channels. Similarly, by placing information describing the location of a control channel in a message associated with handoff, a mobile station avoids the necessity of having to relocate a new control channel associated with the base station to which the mobile has been handed off.
