  • Patent number: 5289678
    Abstract: Apparatus and method are disclosed for monitoring catalytic converter efficiency in treating exhaust gas, for example from an internal combustion engine of a motor vehicle. In a dual closed loop fuel control system having switch-type exhaust gas oxygen (EGO) sensors located upstream and downstream of the catalytic converter, the number of times the downstream EGO sensor switches from rich to lean and/or visa versa is compared to the number of times the upstream EGO sensor switches during normal system operation over the course of a test period. A catalytic converter efficiency value is determined by calculating the ratio of the switching frequencies. The impact of the speed and load dependence of the downstream EGO sensor switching frequency can be reduced by a normalizing effect of the frequency ratio calculation. The efficiency value is compared to a stored value predetermined to correspond to a minimum acceptable efficiency of the catalytic converter.

Each combustion liner has an auxiliary set of circumferentially spaced air slots behind a set of circumferentially spaced primary air holes that introduce compressor discharge air to cool hot spots in the primary combustion zone. The air slots are set at an angle so that the compressor discharge air is admitted into the combustion liner in such a way as to induce a swirling motion in the primary combustion zone. The combustion liner also has a set of circumferentially spaced dilution air holes that are sized and located upstream far enough to maintain an acceptable exit temperature profile and acceptable low level carbon monoxide and unburned hydrocarbons emissions.

  • Patent number: 5289688
    Abstract: This invention relates to an improvement in a process for the separation of a multi-component stream by distillation. A multi-component feed is introduced to a multicolumn distillation system comprising a main column and a side column wherein at least a light component A is separated from a heavier component C in the main column, the lighter component A being removed as an overhead fraction and the heavier component C being removed as a bottoms fraction. The improvement for enhanced recovery of a component in the side column comprises withdrawing a liquid fraction from the main column at a point intermediate the overhead and bottoms and introducing that liquid fraction to an upper portion of the side column. Lighter components are withdrawn from the side column and returned to an optimal location in the distillation system, typically the main column.

  • Patent number: 5289695
    Abstract: A relatively lightweight cooling device and method utilizing adsorption of perspirated water vapor to permit evaporative cooling of a person wearing a sealed suit for defined time periods. The device can be constructed in the form of a rectangular pad or the like having an open cell foam adjacent the person's skin to permit static transport of perspirated water vapor to an adsorbent layer. The open cell foam or a separate material acts as a thermal insulator to prevent heat flow back toward the skin resulting from the exothermic heat of adsorption produced by the adsorbent layer. In lieu of static movement of the water vapor, a small fan can be operatively associated with the fan for actively moving the water vapor to a single point to enhance the evaporative cooling, particularly where a smaller amount of adsorbent material is used.

  • Patent number: 5289699
    Abstract: The invention comprises a non-restrictive, constant pressure refrigerant recycling and cooling unit that interrupts the normal refrigerant cycle to permit a lower temperature liquid to enter the expansion device, and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side of the compressor, which acts to reduce the energy requirement and cost to operate the compressor. This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements.
