Abstract: The container comprises a container body and a label placed on said body. The label has a window through which there can be seen decoration on the body of the container. In the method, before affixing the label on the body, a window is cut out in the label, and then the label is affixed in such a manner that a portion of the body is visible through said window, and decoration is made on said portion of the body of the container.

Abstract: A trailer with display screen storage and support includes infrastructure necessary to store, support and adjust the position and orientation of a large display screen displaying audio/video programming. The trailer has a bed facilitating storage of screen sections on one side of a telescoping support. A portion of the roof is attached to the telescoping support so the telescoping support emerges from within the trailer by lifting the roof portion integrated with the telescoping support. The screen display is separable into top and bottom halves, the top half affixed to the telescoping support and the bottom half separable from the top half and laterally movable to and from a storage position and to and from a position at which it may be releasably connected to the top half of the screen display. The screen display may have ends pivotable from extended to retracted configurations with respect to a center section.

Abstract: A heating appliance having a housing which houses a water and air heating system. The water heating system includes a heat source and a first heat exchanger for transferring heat to a working fluid passing through the housing. The air heating system includes a water-to-air heat exchanger in communication with the working fluid and a source of air, for heating air using the working fluid. The housing defines an upper compartment for the heat source and first heat exchanger, and a lower compartment for the water-to-air heat exchanger.

Abstract: This disclosure concerns the iterative optimisation of schedules, such as calendars. A computer system receives or determines first candidate schedule items. Each candidate schedule item has parameters, and each parameter is fixed or variable and each candidate schedule item comprises a value for each parameter. The system determines second candidate schedule items by permutating the variable parameters of each of the first candidate schedule items and determines a cost for each of the second candidate schedule items. The system then selects a subset of the second candidate schedule items based on the cost and feeds back the subset to be taken as the first candidate schedule items. Since each parameter has a value the cost for each permutation can be determined and the number of candidate schedule items for the next iteration can be reduced. This avoids the exponential complexity of calculating the cost for each possible combination.

Abstract: A condensing heat exchanger of the kind having a primary heat exchanger and a secondary heat exchanger connected downstream of and in series with the primary heat exchanger. The secondary heat exchanger is arranged to at least partially condense combustion gases discharged from the primary heat exchanger. The primary heat exchanger comprising a drum having a longitudinal axis and the secondary heat exchanger comprising a plurality of small diameter tubes arranged by the side of the drum and extending parallel with the longitudinal axis of the drum.
