Inventor: HEI ROBERT D P
IPC: B01D53/38
Filed: 1998-12-30
Abstract: Disclosed is a process for the treatment of a plant fluid effluent containing odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent in either a counterflow or cocurrent flow process. In the process, the effluent is contacted with an aqueous solution comprising a peracid compound and optionally an essential oil. When contacted with the peracid, odor compounds in the effluent are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. In this way, odor removal from the gas is preferred and odor compounds are efficiently transferred into the aqueous treatment solution. The use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert panel when compared to conventional treatment methods.

Title: Method and apparatus for determining the provenance of a data carrying disc
Inventor: HEYLEN RICHARD A A
IPC: G11B20/00
Filed: 1999-09-29
Abstract: The manufacturing process for a data carrying disc, such as a CD, begins with the production of a master, and in the physical manufacturing process of the master, variations are introduced which give the master distinctive physical characteristics and cause errors in the data. The master is used to form generations of discs, and the physical characteristics of the master are passed on down the generations.  A group of discs manufactured from the same source consistently exhibit the physical characteristics of the master, and those physical characteristics are used as a "fingerprint" for identifying that source. To determine the provenance of a data carrying disc, uncorrected data is read from the disc. Information about errors is extracted from the data read. The error information is then compared with characteristic error information which characterises data carrying discs produced from a well known source to determine whether the data carrying disc has been produced from the known source. The error information extracted is representative of errors arising from the physical manufacturing process.
