Granted: 2010-05-25
Abstract: A hay chopper is used for chopping elongated stems of hay into small fragments. The hay chopper comprises two superimposed screens comprising an identical set of slots recessed thereon. When the two screens are well aligned. effective slot windows result from the superimposition of slots from each one of the screens. A chopping element is also provided within the hay chopper, this chopping element comprising sharp-edged blades emerging periodically from underneath said screens through said effective slot windows, in order to cut the hay located onto the chopping element of the hay chopper. By varying the alignment between the two screens, the effective slot windows' width can be adjusted accordingly. It is the width of these slots that will determine approximately the length of the chopped fragments of hay that is allowed to slip therethrough by gravity and/or drive force from the rotating blades.

Title: Control of heat flux in continuous metal casters
Inventor: DESROSIERS RONALD ROGER
IPC: B22D11/124
Filed: 2001-09-14
Granted: 2007-04-17
Abstract: A process of casting a molten metal to form a cast metal strip ingot while controlling heat flux from the cast metal. The process comprises continuously supplying molten metal to a casting cavity formed between a pair of moving continuous casting surfaces that withdraw heat from the molten metal to cause metal solidification, and continuously withdrawing a resulting cast strip ingot from the casting cavity. A gas (e.g. air) containing water vapour substantially without liquid water (i.e. a moist gas) is supplied to the inlet of the casting cavity in a region containing the meniscus formed where the molten metal first contacts the casting surfaces. The moist gas has the effect of adjusting the heat withdrawal by the casting surfaces to minimize surface defects in the cast strip ingot and to avoid undesired distortion of the casting cavity. Furthermore, in those cases where a parting agent is applied to the casting surfaces, the amount of parting agent applied to the casting surfaces may be reduced. The invention also relates to equipment provided for the delivery and dewpoint control of the moist gas.

Abstract: A protocol (i.e. method) and corresponding apparatuses for calculating a session key. Two peers with knowledge of a common Diffie-Hellman permanent key, K perm, and the identity and public key of the other peer. A first peer chooses a first ephemeral private key x and calculates the first corresponding ephemeral public key g x, which is sent to the second peer. The second peer calculates a second ephemeral public key g y in the same manner, and an ephemeral shared key K eph, hashes g y, K eph, K perm, and its identity, and sends g y and the hash to the first peer. The first peer calculates K eph, verifies the hash, and hashes g x, K eph, K perm, and its identity, and sends it to the second peer that verifies this hash. Thereafter, both peers obtain a session key by hashing K eph. The apparatuses may then use the session key to establish a secure authenticated channel (SAC).
