Abstract: A portable game board has a ring-shaped frame containing at least one slide panel marked with indicia used to score trajectories of playing disks slidably launched on the slide panel, which comprises a base panel, an optionally segmented game indicia panel placed on the base panel, or a transparent window slide panel. A pair of base panels having different game indicia are positionable back-to-back within the frame, and selectable by inverting the frame. The board is optionally supportable at an adjustable elevation angle, quantifiably increasing the energy required to propel a disk to distance markers on a panel. An optional platform rotatably supports the game board, facilitating access to board locations by a circle of players. Optionally, an indicia panel contains one or more recessed magnetic slugs; playing disks are provided with one or more ferromagnetic inserts which interact with the slugs to alter the trajectory of a disk.

Abstract: A system for manipulating and transporting relatively large, flat, heavy tabular articles such as portable folding conference tables and construction materials such as plywood or plasterboard sheets comprises a leveraging dolly for lifting an article from a horizontally oriented position at a first location to a vertically oriented position in which the article may be rolled on the dolly to a second location, and a racking cart for receiving and transporting a plurality of articles individually loadable from and onto the leveraging dolly which includes a base rollaby supported by a pair of laterally spaced apart casters, one having a horizontally disposed axle fixed with respect to the base, and the other having a horizontally disposed axle rotatable in a horizontal plane on a vertically disposed swivel attached to the base.

Abstract: A method and apparatus for injecting eggs with injection liquid includes arranging a plurality of eggs in an egg tray, moving the egg-filled tray to an injection station, injecting liquid into the eggs by effecting relative movement between the tray and a plurality of injection needles such that a needle pierces each egg and by forcing injection liquid through each needle into the respective egg, heat-sealing the injection hole in each egg by effecting relative movement between the tray and a plurality of heating devices which apply sufficient heat at the location of the injection hole in each egg to solidify albumin at the hole, applying a coating of liquid hardenable sealing material to the exterior of each egg shell at the location of the injection hole by effecting relative movement between the tray and a source of the sealing material.
