Abstract: A fluidized bed separator (1) includes a feed section (4) between an upper separation chamber (19) and a main separation chamber (6). The feed section (4) has one or more feed pipes (11) extending horizontally and transversely with respect to a body wall (10) of the fluidized bed separator (1). The one or more feed pipes (11) are positioned completely and entirely underneath the inclined plates (17). An external oversize protection apparatus (3) which is separate from and external to the body wall (10) may be operatively coupled to the one or more feed pipes (11). One or more lamella cartridges (49) may be provided within channels (18) of the upper separation chamber (19), and one or more breakaway plates (54, 55) may be inserted within channels (18) to prevent sanding and facilitate insertion and extraction of the lamella cartridges (49).

Abstract: A method for securing a system including a configuration subsystem and a production subsystem. The configuration subsystem is separate from the production subsystem that comprises a plurality of components, a gatekeeper and an entity secured with a first secret value. A generator hosted in the configuration subsystem selects a secret sharing scheme and generates, from an input parameter different from the first secret value, a set of secret shares using the secret sharing scheme. The generator uniquely assigns and securely sends a secret share extracted from the set to each of the components. The gatekeeper gets a subset of the secret shares from the components and constructs a second secret value from the subset using the secret sharing scheme. The gatekeeper computes the first secret value by applying a preset function to the second secret value, and then the gatekeeper unlocks access to the entity using the first secret value.
