Abstract: A method and apparatus for processing mail is provided. Mail is placed into an input bin having a conveyor that conveys the mail towards a feeder. The feeder serially feeds the envelopes by engaging the lead envelope in the stack of mail and displacing the lead envelope transverse the stack of mail. The mail is fed into a shuttle that vertically displaces the envelopes to position the envelopes for entering a justifier.

Abstract: A system and method for increasing the specific output of a combined cycle power plant and providing flexibility in the power plant rating, both without a commensurate increase in the plant heat rate, is disclosed. The present invention demonstrates that the process of upgrading thermal efficiencies of combined cycles can often be accomplished through the strategic use of additional fuel and/or heat input. In particular, gas turbines that exhaust into HRSGs, can be supplemental fired to obtain much higher steam turbine outputs and greater overall plant ratings, but without a penalty on efficiency. This system and method by in large defines a high efficiency combined cycle power plant that is predominantly a Rankine (bottoming) cycle. Exemplary embodiments of the present invention include a load driven by a topping cycle engine (TCE), powered by a topping cycle fluid (TCF) which exhausts into a heat recovery device (HRD).

Abstract: A fuel vapor purging method controls fuel vapor purging during stratified operation. Several factors influence vapor purge control, including fuel vapor concentration in the cylinder and temperature of the emission control device. The fuel vapor passes through the cylinder unburned by maintaining the concentration within allowable limits. The unburned fuel vapor reacts exothermically in the emission control device thereby generating heat. To guarantee that the fuel vapor reacts in the first emission control device, the fuel vapor purge is restricted to a certain temperature range. To guarantee that the fuel vapor does not burn in the cylinder, the concentration is kept to a restricted value.

Abstract: An exhaust gas purification system for an internal combustion engine includes an engine management control system which controls engine air/fuel ratio alternatively at super-stoichiometric level and a sub-stoichiometric level in a three-way catalyst. The engine management system uses a timer and a memory to measure and store cumulative time values including first time over which the engine is operated at the super-stoichiometric level and a second time during which the engine is operated at a sub-stoichiometric level. The alternation between levels is such that the first cumulative time is greater than the second cumulative time with the second cumulative time being sufficient to regenerate at least partially the efficiency of the three-way catalyst activity.

Abstract: A plurality of catalysts (7), (9) are disposed in an engine exhaust passage (13). At least the catalyst disposed downstream of these catalysts comprises a multi-layered catalyst (7) which is covered in a catalyst layer (24a) on the surface and an HC absorbent layer (24b) on an inner layer with respect to a catalyst carrier (23). A ratio of the downstream multi-layered catalyst (7) (catalyst heat capacity/catalyst surface area) is set so that it is greater than the same ratio for the upstream catalyst (9). In this way, temperature increase in the upstream catalyst (9) is advanced, the temperature gradient in the downstream catalyst (7) is increased and temperature rises in the HC absorbent layer are reduced. As a result, the HC emission period approximates the activation period of the catalyst layer (24a).

Abstract: An exhaust manifold is constructed of material varying in thickness. Auxiliary cooling, such as from an air flow, to a portion of the exhaust manifold, permits making this portion thinner than a portion shielded from the auxiliary cooling. This lowers the heat capacity of the thinner material, allowing the exhaust manifold to heat rapidly to the activation temperature of a catalyst. Thus, the catalyst is capable of removing harmful elements from the exhaust gases of an internal combustion engine more quickly, thereby reducing pollution to the atmosphere. Furthermore, an exhaust manifold having this structure is lighter and requires less material than conventional exhaust manifolds, thereby making production easier and less costly.
