摘要： A method and apparatus are provided for reducing pollutants and especially nitrogen oxides, or NOx, in the exhaust gases of an engine. The apparatus includes a device for injecting ammonia into a conduit that extends between cylinder exhaust valves and a catalytic converter, to mix the ammonia with the exhaust gases. Ammonia injection occurs at a location a plurality of inches downstream of the exhaust valves to avoid burning of the ammonia by flames. The injection preferably occurs at a location where the exhaust gases are at a temperature of at least about 1200.degree. F. to cause considerable reaction of the ammonia with NOx in the exhaust gases prior to the gases reaching the catalyst, so less NOx must be removed along the catalyst. To minimize ammonia use, it is injected only for a limited period such as a minute after a cold engine is started when the catalyst is too cold to cause significant reactions, and during operation of the engine at high power levels when the greatest amounts of NOx are produced.

摘要： Groups of DCVS (Differential Cascode Voltage Switch) circuits are interconnected by single-track data transfer connections. Each group contains one or more DCVS tree circuits, through which data signals propagate only on dual-track connections. In each group, at least one DCVS tree circuit is configured as an input boundary tree, and at least one tree circuit is configured as an output boundary tree. All data inputs externally applied to a group, are transferred only through input boundary trees of the group, and all data outputs transferred out of a group leave the group only through output boundary trees of the group. If a group has only a single tree, that tree serves as input and output boundary tree of the group. Each input boundary tree of each group has one or more associated primary shift register latch (SRL) circuits through which all external data inputs to that tree are transferred. Such external data inputs are received through the single-track connections mentioned above. The primary SRL circuits are also used to present predeterminable test data inputs to respective trees, and to collect primary test data outputs representing signals received through the single-track connections. In such usage, the SRL circuits are connected as a scannable shift register. Each output boundary tree has an exclusive-OR (XOR) circuit for indicating if the respective tree is in a legal or illegal state. The XOR circuits connect to secondary scannable SRL circuits for external presentation of illegal state indication. The primary test data outputs together with the externally presented illegal state indications form a basis for detecting and locating any faulty state in any group.

摘要： Cigarette rods are manufactured at high rates of speed using a cigarette making machine having a tongue which is equipped such that water is continuously fed therethrough in order to exit the surface of the tongue which contacts a tobacco filler stream passing through the garniture region of the cigarette making machine. The process of introducing water through the tongue during a cigarette making operation allows the manufacture to produce a continuous cigarette rod of controlled integrity. For example, cigarettes of controlled density and firmness, and having very low amounts of hard spots, soft spots and loose ends, can be manufactured. The process provides for the manufacture of cigarettes at high speeds, and for the manufacture of cigarettes having high filling capacity tobacco blends. For example, cigarettes having blends comprising relatively high levels of volume expanded tobacco can be manufactured efficiently and effectively.

摘要： A scanner for scanning a document positioned against a backing surface to determine the position of the document includes photoelectric transducers which provide electrical scan signals in dependence upon the light reflected from the document and from the backing surface at a plurality of moving scan positions as the scan positions move across both the document and the backing surface. A recognizable background image is defined on the document backing surface such that the photoelectric transducers provide a recognizable pattern of scan signals as the document backing surface is scanned, thereby indicating the position of the document. The recognizable background pattern may include a plurality of stripes on the document backing surface with the stripes extending substantially parallel to the direction of movement of the scan positions. Alternatively, the recognizable background pattern may include a plurality of stripes which extend substantially perpendicular to the direction of movement of the scan positions. Alternate ones of the stripes may be black with intermediate ones of the stripes being white. A circuit means may be provided for detecting the recognizable pattern of the scan signals.
