Patent CA-2418597-A1 (CA)
Title: Adjustable roll core support structure
Inventor: WALT WILLIAM GARY
IPC: B65H16/06
Filed: 2003-02-10
Abstract: In the thermalplastic film manufacturing industry, as the plastic is formed in the forming machine, it is wound on cores generally made of aluminum or stainless steel. The standard machinery manufactures plastic film in three different lengths. Once the film has been wound around the core to a sufficient sizer it is cut and then moved to a storage and transportation device. It has been difficult to keep an inventory of such devices due to the fact that different rolls require different lengths of storage devices. The present invention therefore overcomes this problem by creating a storage and transport device which is capable of adjustment in order to accommodate all three of the normal widths of film.
Patent CA-2419780-A1 (CA)
Title: System and method for displaying advertising in an interactive program guide
Inventor: NICHOLS MICHAEL R
IPC: H04N5/445
Filed: 2001-08-14
Abstract: An interactive program guide containing schedule data for multiple channels and advertising data is provided to viewers on a screen. The advertising may be related to the programs adjacent thereto in the guide and to time slots displayed on the screen. The advertising scrolls in various directions in response to the viewer's scrolling of the grid (200), but at a different pace and according to a different scheme than the scrolling the schedule data itself. For example, the advertising cells (204) may remain on the screen in a predetermined location while the viewer scrolls the schedule data, and then scroll off the screen to be replaced by new ads after a predetermined number of channels scroll off the screen, or on the basis of time slots and/or adjacent channels displayed on the screen. This provides for greater viewer attention to the advertising and for greater control by advertisers over the manner and length in which advertising is presented to viewers.
