Title: Efficient process to produce oxygen
Inventor: HERRON DONN MICHAEL
IPC: F25J3/04
Filed: 1999-01-15
Granted: 2001-04-03
Abstract: The present invention relates to a process for the cryogenic distillation of air in a distillation column system that contains at least one distillation column wherein the boil-up at the bottom of the distillation column producing the oxygen product is provided by condensing a stream whose nitrogen concentration is equal to or greater than that in the feed air stream. The process of the present invention comprises the steps of: (a) generating work energy which is at least ten percent (10%) of the overall refrigeration demand of the distillation column system by at least one of the following two methods: (1) work expanding a first process stream with nitrogen content equal to or greater than that in the feed air and then condensing at least a portion of the expanded stream by latent heat exchange with at least one of the two liquids: (i) a liquid at an intermediate height in the distillation column producing oxygen product; (ii) one of the liquid feeds to this distillation column having an oxygen concentration equal to or preferably greater than the concentration of oxygen in the feed air; and (2) condensing at least a second process stream with nitrogen content equal to or greater than that in the feed air by latent heat exchange with at least a portion of an oxygen-enriched liquid stream which has oxygen concentration equal to or preferably greater than the concentration of oxygen in the feed air and which is also at a pressure greater than the pressure of the distillation column producing oxygen product, and after vaporization of at least a portion of oxygen-enriched liquid into a vapor fraction due to latent heat exchange, work expanding at least a portion of the resulting vapor stream; (b) work expanding a third process stream to produce additional work energy such that the total work generated along with step (a) exceeds the total refrigeration demand of the cryogenic plant and if the third process system is the same as the first process system in step (a)(1), then at least a portion of the third process stream after work expansion is not condensed against either of the two liquid streams described in step (a)(1); and (c) using the work which is generated in excess of the refrigeration need of the distillation column system to cold compress a process stream at a temperature lower than the ambient temperature.

Abstract: This invention is a device for automatically watering unattended houseplants with ordinary tap water. The device controls the rate of discharge of water from a reservoir by means of a replaceable multilayer sandwich-type flow control wafer, which is made of several layers of deformable gasket material, laboratory filtration paper, and thin flexible plastic. The gasket and plastic layers contain designed patterns of through-holes and passages which force the water to flow over and through the filtration paper to control the rate of release of water from the reservoir. The design also uses the filtration paper to remove particles from the tap water which could clog the system and stop the flow. Over the course of the watering cycle the water gradually loosens the adhesive bonds between the filtration paper and the plastic, which increases the effective flow area of the filtration paper to partially compensate for the reduction in pressure head which occurs as the reservoir empties, thus keeping the water flow rate more constant over the watering cycle than it would be if controlled only by a simple orifice or filter. The watering device includes registration and compression rings which position and seal the flow control wafer, a concave funnel-like reservoir opening for filling the device in situ, and a narrow integral spike which supports the device in the plant soil and creates an open vertical passage which facilitates water penetration deep into the plant's root system.

Abstract: A method is disclosed for characterising the subsurface levels of the Earth with a greater degree of accuracy than hitherto. Seismic data samples are migrated and stacked, for example according to known techniques and then spectrum analysed. The spectral analysis is applied to a feature of the subsurface and, for example, a particular layer bounded by a pair of horizons would be subject to volume reflection spectral analysis. The analysis is carried out using an orthogonal base by defining the reflection signals in terms of coefficients to a set of orthogonal polynomials. Additional seismic characteristics or attributes may be directly calculated from the polynomial coefficients. These coefficients represent the characteristics of the layer to a high degree of accuracy and may be compared with spectra derived a priori (for example synthetic spectra or previously characterised spectra) to further assist in analysis of measured seismic data.

Abstract: The diagnostic system of the present invention monitors and accumulates thermal signatures or characteristics during at least one operational mode of a cooking appliance (105). These thermal signatures or characteristics are collected through the same temperature sensor (115) used to regulate the temperature of the cooking appliance and then stored in, for example, a look-up table (130).      Advantageously, this may be accomplished without the need for special sensors or interface boards. The thermal signatures or characteristics may include first order or higher order temperature gradients, as well as temperature profiles. The stored thermal signatures provide a baseline from which the diagnostic system can detect and identify whether the cooking appliance is working under normal operating conditions. In an alternative embodiment, the diagnostic system monitors and accumulates the cooking profiles for either a single food product or a plurality of food products. The current cooking profile is graphically displayed and compared against the master cooking profile (520) to flag food products that are improperly cooked or not cooked to the proper degree of doneness. Such monitoring and analysis substantially eliminates any possible health risks. Also, such master cooking profiles also provide a baseline for diagnosing between normal and faulty cooking conditions.
