Abstract: A soda straw box is installed in a dispenser by pushing the box full of straws into the dispenser receptacle. An opening member in the dispenser has a slot into which a corner of the box is pushed so that the corner panels fold together. One corner panel of the straw box is an anchor flap that folds as it is pushed into the opening slot. One or two other flaps are hinged either directly or indirectly to an edge of the anchor flap to assist in forming an opening in the box to allow the straws to fall down into the dispenser. The flaps of the box are all hinged for movement into the box during the opening process.

Abstract: An internal combustion engine having combustion chambers that rotate about a main shaft axis in a step-wise manner. A first and second rotor each have elongate pistons that are interdigitated so that when one rotor rotates with respect to the other rotor, some combustion chambers between the interdigitated pistons decrease in volume and other combustion chambers increase in volume. Fuel mixture and exhaust apparatus forms one end wall of the combustion chambers to feed a fuel mixture to the increasing-volume chambers and extract the exhaust gasses from other decreasing-volume chambers. The fuel mixture and exhaust apparatus rotates in a direction opposite the first and second rotors, and twice the rotational rate of such rotors.

Abstract: An internal combustion engine having combustion chambers that rotate about a main shaft axis in a step-wise manner. A first and second rotors each have elongate pistons that are interdigitated so that when one rotor rotates with respect to the other rotor, some chambers between the interdigitated pistons are reduced in volume and other chambers are increased in volume. Respective one-way bearings connect the first and second rotors to the main shaft to incrementally rotate it. Fuel mixture and exhaust apparatus is connected to one end of the engine to feed a fuel mixture to the increasing-volume chambers and extract the exhaust from other decreasing-volume chambers. At the same time, yet other chambers are experiencing compression and ignition cycles. An oil pump is driven by the first and second rotors for circulating a lubricant from a reservoir, through the engine parts to be lubricated and then back to the reservoir to cool the lubricant.

Abstract: A straw dispenser that hold two individual straws, sequentially selected from an inventory of straws. The upper straw is staged in a position to fall, and the lower straw is in a position made available to a person. The person grasps the available straw and pulls the same, which moves a lower movable part of the dispenser. The forward movement of the lower movable part allows the upper staged straw to fall downwardly to a transitory position, and during backward movement of the lower movable part the straw moves from the transitory position and is made available. At the same time a successive straw is selected from the inventory and held in the staged position. The person need not touch any other part of the dispenser or touch other straws to be dispensed. A subsequent straw cannot be dispensed until the available straw has been removed from the dispenser.

Abstract: A straw box engageable with a dispenser during dispensing of straws to a user. The straw box includes an elongate door that can be opened while the straw box is engaged with the dispenser so that the dispenser is not required to be turned upside down. A pull tab is attached to the door and is accessible so that the door can be opened after the straw box is attached to the dispenser. The straw box remains engaged with the dispenser until all the straws have been fed from the straw box to the dispenser, and thus to users of the straws.

Abstract: A key mechanism that makes it possible to fix the key inside the cylinder bolt lock outphased from the original combination, thereby preventing the cylinder of the bolt lock from turning. The security of the key mechanism is also enhanced as a cylinder tumbler engages within a slot of the key blade and the key cannot then be expelled from the cylinder bolt lock. Therefore, it is impossible to insert another key or picklock from the other side of the cylinder bolt lock.
