  • Modular mold and die assembly
    Patent number: 6780362
    Abstract: Modular die or mold assemblies comprise a platform, and at least one die or mold unit which is releaseably connected to the platform. The invention permits rapid changing of molds or dies, especially in the manufacture of detergent bars, such as soap bars. Surface ornamentation such as logos can be imparted to the detergent bars either directly from the stamping surface of the dies, from the stamping surface of the dies through an elastomeric lining, or from the surface of the elastomeric lining; in the latter case the indicia is imparted by a mold used to prepare the lining. The modular molds may be used where it is desired to coat the dies with elastomer, particularly where logos are imparted to the elastomeric layer, and where it may be desirable to change the logos, e.g., by changing the modular mold units.

  • Method for finding solutions
    Patent number: 6768973
    Abstract: A method is described for using a computer in finding solutions to a problem dependent on a number of criteria. A model algorithm is provided for each of the criteria, each model algorithm providing a prediction for a corresponding criteria when a candidate solution is inputted into the model algorithm. At least one model algorithm provides a prediction with a prediction error bar for the corresponding criteria. Criteria are selected to optimise a set of candidate solutions. An algorithm is provided for optimisation of the set of candidate solutions in accordance with the selected criteria. A first set of candidate solutions is provided and the optimisation algorithm generates one or more new candidate solutions. All candidate solutions are inputted into the number of model algorithms to obtain predictions and at least one prediction error bar.
