Abstract: An anti-reflective coating for a substrate which includes an outer metal oxide layer with a refractive index greater than the refractive index of the substrate. The invention also relates to a method for making the anti-reflection coating.

Abstract: There are described methods and apparatus for assessing foams generated from liquids. Existing methods are slow and labour intensive. The new methods involve generating foams from liquids and optically obtaining information to enable parameters relating to the generated foam to be measured. Although single samples of liquids may be processed the methods are particularly suited to processing multiple samples to obtain data relating to foams at a high rate. The apparatus includes automated handling equipment to enable samples to be moved between workstations and relative to associated optical equipment that is used to obtain information relating to the foams.

Abstract: An assembly is presented. The assembly includes a rotatable cylinder including product-holding members positioned on the circumference of the cylinder. Several cylinder passageways are deployed within the cylinder, which provides fluid communication between the product holding members and a vacuum. As such, a suction force may be applied from the vacuum through the cylinder passageway to the product-holding member. A locating pin is deployed on one end of the rotating cylinder. The locating pin enables rotation of the cylinder and a positive stop of the cylinder in an aligned position. The locating pin works in conjunction with an O-ring so that vacuum is only applied to one cylinder and one set of product holding members when the locating pin is locked in the positive stop position.

Abstract: A substrate coating and method of applying the same in which the coating provides UV blocking and AR properties and in which at least one of the layers is formed of a combination of zinc oxide and a stabilizing secondary metal oxide.
