IPC: A47B53/02
Filed: 2002-03-25
Abstract: A mobile storage system includes a series of carriages which are movably mounted to a series of rails supposed on a surface such as a floor.     Storage units, such as drawer-type cabinet, are adapted to be engaged with each carriage, and are movable on the rails along with the carriages. Each carriage is modular in construction, and incorporates a series of mobile housing assemblies interconnected by a structural cross-brace arrangement. At least one end of the carriage includes an end panel arrangement which overlies a sidewall of an endmost one of the storage units. The end panel arrangement includes a frame defining an interior, and one or more cover members are demountably secured to the frame so as to selectively cover the interior of the frame and to conceal the sidewall of the endmost storage units. A series of retainer members are interconnected with each carriage, and interact with the rails so as to prevent upward movement of the carriage relative to the rails. The retainer members are secured to the mobile housing assemblies, and each retainer member is engaged within a groove defined by an underlying one of the rails. The retainer members further provide the dual function of mounting the storage units to the mobile housing assemblies. The carriages and the rail and floor system are of a modular construction, enabling; the components of the system to be shipped in knock-down form and assembled on site, and also to be expanded or contracted after initial installation.

Title: Recordable storage medium with protected data area
Inventor: LINNARTZ JOHAN P M G
IPC: G06F21/80
Filed: 2001-05-08
Abstract: The invention relates to a method of storing data on a rewritable data stora ge medium, to a corresponding storage medium, to a corresponding recording apparatus and to a corresponding playback apparatus. Copy-protective measure s require that on rewritable storage media some data must be stored which shal l not be modifiable or erasable by consumer end products. A practical problem is the storage of large quantities of such data in a fixed data area. Typically  the capacity is limited to a few bits. Meanwhile the amount of copy protecti on data that needs to be stored may well exceed the storage capacity available in the read-only fixed data area. The invention therefore proposes to write the  copy protection data as system data in the recordable data area (4), e.g. as  part of the formatting of the medium (1). A cryptographic summary is compute d and also stored in the recordable data area (32) or in the fixed data area ( 2) such that a cryptographic relationship between the fixed data area (2) and t he system data area (3) is provided. A playback or replay apparatus will only accept a storage medium with a valid combination of copy protection data and  fixed data.

Title: Ameliorations apportees a une bande d'ecriture electronique
Inventor: LIN YUAN
IPC: H05B37/02
Filed: 1999-08-02
Abstract: L'invention concerne les améliorations apportées à une bande d'écriture électronique offrant les fonctions d'écriture de caractères et de modification des modèles et se composant d'un système de commande, d'un dispositif d'éclairage, d'un circuit de relais, d'un système d'interruption et d'une alimentation en puissance d'interruption. Le système de commande génère des ondes dent de scie et des ondes en cascade transmises au dispositif d'éclairage pour exciter la lampe. On déclenche par le circuit de relais les ondes dent de scie et les ondes en cascade pour exciter successivement les lampes dont la vitesse d'allumage est réglée par le dispositif de contrôle de la vitesse du système de commande. Ainsi, la dernière lampe allumée déclenche le système d'interruption qui transmet un signal d'interruption au système de commande de manière à émettre une faible tension afin d'éteindre la lampe de la bande d'écriture. Si les bandes d'écriture nécessitent plus de lampes, le système de commande peut être remplacé par le circuit de relais afin d'alimenter le circuit de relais de manière à connecter les lampes plus longtemps.

Title: Perforated current collectors for storage batteries and electrochemical cells, having improved resistance to corrosion
Inventor: LIN PETER K
IPC: H01M4/82
Filed: 2001-05-24
Abstract: A process for enhancing chemical stability and corrosion resistance is described for perforated current collectors made by continuous production processes for use in electrochemical cells, including storage batteries such  as lead-acid batteries. The process relies on utilizing a strip processing method, selected from the group of reciprocating expansion, rotary expansion  and punching, to perforate the solid metal strip to form a grid or mesh, as a deformation treatment. The perforation- deformation treatment is followed in  rapid succession by a heat-treatment to obtain a recrystallized microstructu re in the current collector and optionally by quenching to rapidly reduce the temperature to below approximately 80 ~C. The process yields an improved microstructure consisting of a high frequency of special low .SIGMA. CSL gra in boundaries (> 50 %), exhibiting significantly improved resistance to intergranular corrosion and cracking. Perforated current collectors produced  with this process from a solid lead-alloy strip exhibit superior growth and corrosion properties when employed as positive grids in a lead-acid battery.
