Abstract: A system, method, process, and mechanism for fulfilling multi-vendor orders within a drive-through complex with a vertical transport system that delivers the multi-vendor orders to pick-up stations located below the floors with the vendors. The system receives an order from a user device of a user, wherein the order includes at least two sub-orders. The sub-orders are processed based at least on the preparation times. The sub-orders are tracked and an available drive-through lane with an available pick-up station is determined for the order including the sub-orders. Notifications may be sent to a user or third party user for order pick-up. When the order is complete, it is consolidated and the order is transferred to the available pick-up station.

Abstract: Methods of making metal oxide articles, preferably iron oxide articles, and articles thereby produced. The method comprises the steps of slightly pressing powder to a compact, the powder consisting essentially of a first oxide of the metal; and subjecting the compact to a heat treatment that causes the powder to sinter into a unitary body and results in the transformation of at least a portion of the first oxide to a second oxide by oxidation or deoxidation during the heat treatment. In disclosed embodiments, the heat treatment is conducted either in air at atmospheric pressure or at a subatmospheric pressure. The method optionally includes more heating/cooling steps resulting in additional oxidation/deoxidation cycles. Sintered iron oxide articles of the invention have high mechanical strengths and interconnected pore structures, providing for efficient filtering of liquids and gases.

Abstract: Catalytic metal additives that directly dissolve in gasoline in concentrations providing efficient and economical three-way catalysis of exhaust gases from internal combustion engines. The additives are compounds of noble (e.g., Pt, Pd, Au and Rh) or non-noble (e.g., Re) metals. The preferred compounds have polar metal ligand bonds, preferably with inorganic ligands such as halogens, oxygen, etc., and/or salts with highly ionic (polarizable) cations such as of alkali metals. The preferred additive is a combination of X.sub.2 PtCl.sub.6, RhCl.sub.3 and XReO.sub.4, where X=K, Rh or Cs. A combination of these finely ground materials is fabricated into a briquette or filter which is deposited in the gas tank or placed in a gas line. The catalytic metals are carried by the exhaust gases through the exhaust system where they are deposited on surfaces of the system to convert toxic emissions.
