Abstract: Methods and devices automatically determine a base color gamut of base marking materials and extension color gamuts of extension marking materials. As each print job is received, these methods and devices automatically evaluate the print job to determine the print job color gamut. Then, the methods and devices can automatically determine the closest match between: the print job color gamut; and the base color gamut or one of the extension color gamuts to identify a matching color gamut. Further, these methods and devices automatically output the matching color gamut (and potentially a corresponding interchangeable supply container, if the matching color gamut is one of the extension color gamuts) by, for example, displaying the matching color gamut and the corresponding interchangeable supply container in at least one additional column in a print queue, or displaying the matching color gamut and the corresponding interchangeable supply container in a separate gamut queue.

Abstract: A sheet supply device has a bottom contacting or resting on an external surface. The sheet supply device stores sheets of media and supplies the sheets of media to a processing device. The sheet supply device comprises a controller device, a platform supporting the sheets of media, and a foot-activated user input device positioned at the bottom of the sheet supply device adjacent the external surface. The platform moves upward (in a first direction away from the external surface) to supply the sheets of media to the processing device, and the platform moves downward (in a second direction toward the external surface) to allow the sheets of media to be loaded onto the platform. Operation of the foot-activated user input device causes the compartment to open and/or the platform to move downward (in the second direction).

Abstract: A container 22 includes a shell 24 made from a polymer, for example PET, and incorporating a catalyst, for example a palladium catalyst. A closure 40 incorporates a plug which includes a source of hydrogen, for example a hydride. In use, with container 22 including a beverage and closure 40 in position, the headspace in the container will be saturated with water vapor. This vapor contacts the hydride associated with plug 42 and as a result the hydride produces molecular hydrogen which migrates into the polymer matrix of shell 24 and combines with oxygen which may have entered the container through its permeable walls. A reaction between the hydrogen and oxygen takes place, catalysed by the catalyst, and water is produced. Thus, oxygen which may ingress the container is scavenged and the contents of the container are protected from oxidation.

Abstract: A closure (40) for a container incorporates calcium hydride and a matrix material as a hydrogen-generating composition. In use, hydrogen is generated which reacts with oxygen permeating a container associated with the closure and a catalyst associated with the container catalyses reaction of the hydrogen and oxygen to produce water, thereby scavenging the oxygen. The composition of calcium hydride and matrix is also claimed.

Abstract: A polymer additive for improving the reheat characteristics of a polymer or polymeric composition comprises an inorganic material which is such that a 2.5 mm thick polyethylene terephthalate plaque incorporating the inorganic material has, when tested, an absorption ratio of less than 0.9, wherein the absorption ratio is either the ratio of A1/A2 or the ratio A1/A3, wherein: A1 is the maximum absorption between 400 nm and 550 nm; A2 is the maximum absorption between 700 to 1100 nm; A3 is the maximum absorption between 700 to 1600 nm. Preferred inorganic materials are titanium nitride, indium tin oxide and lanthanum hexaboride.

Abstract: Polymer compositions, for example of polyethyleneterephthalate bottles or preforms, include a reheat additive which has reducing transmission/increasing absorbance across the IR region as the wavelength increases. The reheat additive may be a titanium nitride, made by a plasma vapor deposition technique. Advantageously, the material may be used at a lower level than hitherto known materials or may be used at the same levels as hitherto but provide a greater reheat effect. Example 3a shown in the figure illustrates the absorbance of a preferred material.

Abstract: A method to render stone, ceramic, or cementitious structures water repellent is disclosed. The method includes the step of contacting the stone, ceramic, or cementitious structures with an alkylphosphonic acid. The alkylphosphonic acid can be dispersed in an aqueous medium and can be at least partially neutralized with ammonia, an amine, or a basic alkali salt.

Abstract: A closure 40 for a container body includes a liner 46 which incorporates a hydrogen generating device comprising a hydride which generates hydrogen on contact with moisture. The liner may be an interference fit within the body 42. The liner 46 and other liners described may include control means for controlling passage of moisture to the hydrogen generating means and/or sealing means for sealing the closure to a container. In use, with the closure secured to a container, water vapour passes into liner 46 and contacts the hydride which generates hydrogen. A reaction between hydrogen and oxygen which has passed into the container takes place, catalysed by a catalyst, and water is produced. Thus, oxygen is scavenged.

Abstract: A closure (40) includes a body (42) with a screw threaded portion (44) for engaging the closure with a container, for example a bottle. Inwards of portion (44) is a liner (46) comprising a hydrogen generating device, wherein the liner includes one layer (48) which incorporates a hydride dispersed in a polymeric matrix and, on opposite sides of layer (48) are arranged PET layers (50, 52). Layer (50) is arranged to act as a control layer to control the rate of passage of water vapour from the beverage in the container to the hydride containing layer (48) and thereby control generation of hydrogen by the hydrogen generating device. In use, water vapour passes through layer (50) and contacts the hydride associated with layer (48) which results in production of molecular hydrogen which combines with oxygen which may have entered a container with which the closure (40) is associated.
