Abstract: A container includes a body portion having a side wall and a base wall, a first lid, and a second lid. The first lid is removably mounted to the side wall and the body portion and the first lid forms a first compartment. The second lids is connected to the body portion along a hinge and forms at least a part of the base of the container. The body portion and the second lid form a second compartment which is located on the opposite side of the base wall to the first compartment.

Abstract: A method of packet encryption and decryption that allows for pipelining. The first step is to identify the packets in a message to be encrypted. Then, a unique number is assigned to each packet. A value R is acquired. Then, a first register is initialized. An initialization vector IV is generated. Then, the first register is stepped a user-definable number of times. Then, a packet is selected. R and the unique number are combined. Then, a second register is initialized. A checksum is generated. Then, the packet is divided into blocks. A block is selected. Then, the checksum is combined with the block and designated the checksum. The block is encrypted. Then, the first and second registers are stepped. These steps are repeated for each block. Then, the checksum is encrypted. After the blocks are encrypted, the unique number, IV, the ciphertext of each block, and the encrypted checksum are transmitted. If there are any other packets to encrypt then the steps are repeated.

Abstract: A flexible liner (10) for a hopper or chute (40) has a plurality of overlapping flexible liner panels or tiles (20) secured to the walls (41,42) of the hopper or chute (40) by fixing strips (30). Each flexible liner panel or tile (20) has an elongate body (21) and a flexible fin or flap (22) formed integrally of elastomeric material, where the flexible fin or flap (22) extends at an acute included angle (?) (in the direction of flow of material through the hopper or chute (140)) to the side walls (41,42) and the Shore A hardness of the elongate body 21) is equal to, or greater than, the Shore A hardness of the flexible fin or flap (22).
