Process for shredding a tobacco sheet and apparatus
Patent No. 8,991,404
A process and apparatus for shredding tobacco sheets, especially tobacco sheets formed of reconstituted tobacco particles with guar and sugar comprises rotating opposing sets of cutter discs in a partially overlapping relation so as to establish a nip.

Slide card for selective insertion and withdrawal from a sleeve
Patent No. 8,991,603
A slide card for selective insertion and withdrawal from a sleeve includes a base panel, a locking panel and at least one embossment. The locking panel is integrally formed with the base panel and hingedly connected to one of the opposing end edges of the base panel to engage at least part of the sleeve to lock the base panel in the sleeve. The locking panel extends from the one of the opposing end edges of the base panel to its free end edge that is located opposed to the one of the opposing end edges of the base panel. The at least one embossment is formed on one of the opposed surfaces of the base panel. The at least one embossment projects from the one of the opposed surfaces of the base panel and is spaced apart from receiving blisters on the base panel.

Remote login arrangement for heterogeneous systems using centralized authentication
Patent No. 9,003,504
Methods and systems for authenticating a remote user across heterogeneous authentication systems are disclosed. One method includes receiving domain user credentials at a first heterogeneous authentication system, and transmitting the domain user credentials from the first heterogeneous authentication system to an authentication interface associated with a second heterogeneous authentication system. The method also includes transmitting the domain user credentials from the second heterogeneous authentication system to a centralized authentication system, and receiving at the authentication interface a validation message from the centralized authentication system, thereby authenticating the user. The method further includes determining a local username at the authentication interface based on the domain user credentials. The method includes using the local username to authenticate the user within the first heterogeneous authentication system.
