Granted: 2011-06-21
Abstract: A pseudo-stable phase-splitting solvent composition that forms a single liquid phase when subjected to mild agitation and retains that single phase while the composition is applied to a surface, but which forms two or more laminar liquid phases promptly after being applied. A concentrated solvent film forms on the surface, under a film containing the other phase. The solvent preferably is denser than water, and the composition preferably is diluted with water. This enables the solvent to attack the surface at near full strength, and provides a water seal over the solvent film. The solvent composition can be used full strength or in diluted form for cleaning, reducing the microbial population of, or degreasing a variety of surfaces, and for stripping a variety of difficult-to-remove coatings from surfaces.

Abstract: It is based on the use of fresh water available in the storage tank of the ship (11) and saltwater from the sea (2), which are propelled by corresponding pressure groups (3-12) towards a homogenizing tank (10) through a mixing valve (8, 17 and 9) so that it is regulated depending on the desired degree of salinity of the resulting mixture. It is controlled at all times by a salinity cell (31) assisting a conductivimeter (32) and acting upon flow regulating valves (8, 17 and 9) that control the resulting amount of fresh water and saltwater. Moreover, an ozone generator (19) that is assisted by an air dryer (20) supplies ozone to the homogenizing tank (10) serving as germicidal device through an ejector (21).

Abstract: A scalable messaging system for data transmission between the network devices (10) such set top boxes (10), and a central system server (200), such as server which maintains a database (210) of event logs for the network. Individual routers (250-n) at the data center broadcast announcement packet indicating that they are available to accept messages from the network devices. The announcement message contains at least an identification of the router and the manner in which messages may be sent to it, e.g., one ore more connection socket numbers and/or network addresses. The frequency at which availability messages are sent by the routers is preferably dependent upon the relatively loading of the individual router. Thus, the more heavily loaded a particular router becomes, the less often it will broadcast an availability message; the more lightly loaded it becomes, the more often such messages are broadcast.

Abstract: A method of producing microparticles and nanoparticles of a solute via the extraction of solvent, having the solute dissolved therein, from an emulsion from source (114) using a supercritical fluid form source (112). The solute to be precipitated is dissolved in the solvent to form a solution, and the solution is dispersed in an immiscible or partially miscible liquid to form an emulsion at source (114). The particles are produced via the extraction of the solvent from the emulsion using the supercritical fluid in vessel (110). The process can produce an aqueous suspension of particles that are substantially insoluble in water, and the solvents used in the process to form the emulsion initially can be recovered and recycled from vessel ports (120) and (122).

Granted: 2008-09-02
Abstract: A high efficiency heat exchanger is shown which can be incorporated into a finned tube water heater. The heat exchanger has a pair of flow manifolds each having a water inlet and a water outlet and a series of connecting openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. When incorporated into a water heater, a burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle. A method of corrosion protecting the heat exchanger is also shown.

Abstract: A method is disclosed for classifying plant embryos according to their quality using a penalized logistic regression (PLR) model. First, sets of image or spectral data are acquired from plant embryos of known quality, respectively. Second, each of the acquired sets of image or spectral data is associated with one of multiple class labels according to the corresponding embryo's known quality. Third, sets of metrics are calculated based on the acquired sets of image or spectral data, respectively. Fourth, a penalized logistic regression (PLR) analysis is applied to the sets of metrics and their corresponding class labels to develop a PLR-based classification model. Fifth, image or spectral data are acquired from a plant embryo of unknown quality, and metrics are calculated based therefrom. Sixth, the PLR-based classification model is applied to the metrics calculated for the plant embryo of unknown quality to classify the same.
