Abstract: A method for carrying out a gas exchange in a cylinder of an internal combustion engine is provided. The cylinder is connected to a gas line section via a valve. An actuator adjusts a gas pressure in the gas line section. The valve closes at a fixed point in time in a working cycle of the internal combustion engine in case of a constant torque of the internal combustion engine. The method includes the steps of recognizing a torque change request; determining a target value for the gas pressure in the gas line section in dependence on the torque change request; and determining a variable point in time for closing the valve as a result of the torque change request, wherein the variable point in time is shifted in the working cycle relative to the fixed point in time in dependence on the target value of the gas pressure.

Abstract: A plastic mailbox has a postal compartment mounted on top of a newspaper compartment which in turn is mounted on top of a two piece upright plastic support. The laterally opposite side wall structures and arched top structure of the postal compartment and the laterally opposite side wall structures and the bottom structure of the newspaper compartment have inner and outer walls for strength. The postal compartment is strengthened by a pair of longitudinally extending rows of upward bulges or pockets in the arched ceiling segment of the inner wall of its arched top structure. The postal compartment are further strengthened by a forward projecting lip encircling forward end of the mailbox. A partial wall at the rear of the newspaper compartment serves as a newspaper stop and as a reinforcing structure.

Abstract: A plastic mailbox of modular construction includes a postal compartment and a newspaper compartment. The postal compartment includes a floor component which serves as a roof for a newspaper compartment positioned beneath the postal compartment. The postal compartment floor serves as an interconnecting member between the postal compartment and the newspaper compartment and is hidden from view by having its laterally opposite sides disposed in registering recesses formed in the side walls of the postal and newspaper compartments. A partial rear wall in the newspaper compartment serves as a stop for newspapers inserted into the open ended newspaper compartment.

Abstract: A mailbox is provided with a rain intercepting structure which includes a groove in a shoulder formed on the laterally opposite sides and the top of the mailbox door and a ridge on the inside of the mailbox doorway in juxtaposed registration with the groove. Moisture impacting the ridge is diverted to the groove and drains out its bottom ends, thus protecting the mail against rain damage.

Abstract: A mailbox is secured to a support by a tongue and groove connection. The support may be formed of two side by side pieces, which are maintained in assembly by the tongue and grove connection. The two pieces of the support may have mating protrusions and pockets preventing sideway displacement of the support pieces from one another.

Abstract: An elongated vertical plastic ground mount post for mailboxes is provided having an upper portion suitable for supporting a mailbox, as by insertion into a hollow support column of a plastic mailbox, and a lower portion with vertically spaced notches which serve to retain the post in place in the ground when earth is compacted against the lower portion.
