Abstract: A computerized system for transacting the purchase and sale of consumer motor fuels between motor fuel merchants and retail consumers through software on a mobile or desktop connected device for periods in the future through the simultaneous execution of multi-party, multi-layered contingent transactions and pricing algorithms to ensure that all inter-related motor fuel merchant transactions are simultaneously transacted upon a retail consumer purchase execution. Motor fuels include refined products such as gasoline and diesel fuel, renewable fuels (e.g. ethanol, biodiesel), natural gas (including liquefied natural gas), jet fuel and electricity.

Abstract: A mounting system is disclosed for removably mounting rollers and cylinders in a machine for quick and easy removal and replacement by other rollers and cylinders. The mounting system provides for rapid separation of the journal from the roller or cylinder so that only the roller or cylinder is removed, and the mounting system has particular applicability with respect to ink rolls in printing machines.

Abstract: Cross cuts for forming the ends of a tab on a sheet, for example a glue tab on a corrugated paperboard container blank, are performed by independent rotary cutter units. Each cutter unit has a spirally convoluted blade which, as it rotates, cuts progressively inwards from an outside edge of the sheet towards an opposite outside edge. As the sheet is conveyed along, a downstream cutter unit cuts the leading end of the tab, and an upstream cutter unit cuts the trailing end. After each cut, the cutter remains at rest with its blade in an inoperative position out of the path of any oncoming sheet. A sensor senses the next oncoming sheet and initiates the cutting via a computer. These rotary cutters mitigate skewing of the sheets while being cut.

Abstract: Apparatus, for example for processing sheets of corrugated paperboard in the production of container blanks, has a pair of feed rolls between which the sheets are fed while passing through the apparatus, and a pair of side frames in which the feed rolls are rotatably mounted one above the other. The upper of the feed rolls is journalled in bearings mounted eccentrically in bearing housings rotatable in holes in the side frames. Gearing is provided for adjustably rotating the bearing housings in the holes to move the upper feed roll respectively away from and towards the lower of the feed rolls. A pair of wedges act upon each bearing housing and are disposed in a cavity in each side frame below and communicating with the respective bearing housing. The wedges are moved towards each other by a screw bolt and/or a fluid cylinder to pre-load the bearing housings upwards in their holes.

Abstract: A method and apparatus for mounting a die, particularly a rigid cutting die, on a die cylinder includes having a bubble along a seal on the die to bridge any gaps between the die and the die cylinder when the die is initially positioned on the die cylinder. This bubble seal enables a vacuum to be applied between the initially positioned die and the die cylinder to pull the die down against and into conformity with the surface of the die cylinder, at the same time flattening the bubble seal. A key at a trailing edge of the die locates in an axial keyway in the die cylinder to circumferentially position the die; a bolt is then inserted at a leading edge of the die to establish axial location. During operation the die is held in position by the vacuum. Beam sensors and light reflectors may be incorporated to sense when a wrong die is present and shut down the apparatus.
