摘要:
The invention relates to a method of detecting gram-negative bacterial endotoxin using antibody capture combined with amoebocyte lysate chromogenic detection. The method is highly sensitive and rapid and may be used for detection of specific endotoxin. In a particular application, picogram levels of Haemophilus influenzae type b endotoxin are detected in plasma taken from previously infected mammals. In another particular application, the method is applied to the detection and diagnosis of disease, through the detection of endotoxin from disease-causing organisms. A specific example is the diagnosis of chancroid through the detection of endotoxin from H. ducreyi.

The invention is a method and system for testing variations of website content useful to optimize website visitor conversions. The invention helps website operators create content variations, and then scientifically test and measure the impact of those variations on conversion rates. The invention includes a method of using a reverse proxy server to introduce page variations on existing website content without needing to modify the existing web server. Using the reverse proxy server, the invention automatically injects values, associated with website variations, into web page tags used with web analytics platforms. The invention makes it possible to test any number of website variations and access such data from within web analytics platforms. The invention also provides a method to automatically transform web page tags of a first web analytics platform to web page tags of a second web analytics platform to easily try new third party web analytics solutions.
摘要:
A manual spray cleaner for removing dirt and stains from fabrics and carpets comprising a spray bottle having two separate chambers and a single dispensing spray outlet for dispensing controlled amounts of liquids from each of the chambers. One of the chambers has a fabric/carpet cleaning composition therein and the other chamber has an oxidizing composition that enhances the cleanability of the fabric/carpet cleaning composition. The fabric/carpet cleaning composition and the oxidizing composition are simultaneously drawn from their respective chambers and mixed together at the time that they are dispensed from the spray bottle. At least one of the oxidizing composition and the fabric/carpet cleaning composition includes a fabric/carpet protectant. The two compositions are mixed before or after they are sprayed from the bottle. The two compositions can be pressurized with an aerosol propellant or drawn from their respective chambers by a mechanical pump.

A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.

A manual spray dispenser for dispensing a mixture of two compositions comprises a container having a first and second chamber and a single dispensing spray outlet. At least one of the chambers has a separator in the form of a pouch for physically separating the contents of the container from an interior surface of the chamber. One of the first and second chambers contains a first composition and the other contains a second composition. The dispenser further contains a dispensing system for simultaneously dispensing the first composition and the second composition, mixing the two compositions together, and dispensing a mixture of the two compositions from the container under pressure. An aerosol propellant is between the separator and the interior surface of the at least one of the first and second chambers for pressurizing the composition in the pouch for dispensing the contents thereof through the dispensing system under pressure.

A package for delivering a cleaning solution to a surface to be cleaned comprises a housing, a pocket in the housing having at least one piercing projection extending into the pocket and a passageway between the pocket and the surface to be cleaned beneath the housing. A sealed packet containing a cleaning solution can be configured to fit into the pocket and can have at least a portion of an outer surface thereof adapted to be pierced by the at least one piercing projection when the packet is placed in the pocket. The cleaning solution can be discharged from the packet when the packet is positioned in the pocket and the packet is pierced by the at least one piercing projection. The cleaning solution can then be dispensed through the passageway onto a surface to be cleaned.
摘要:
An aerosol spray cleaner comprises two containers and a dispenser with a single dispensing spray outlet. One container has a cleaning composition and the other has an oxidizing composition. An integrally molded actuator includes a resiliently cantilevered lever connected to container valves to simultaneously open the valves to dispense the two fluids through the dispensing spray outlet. A handle extends laterally of the containers so grasp the handle and depress the actuator with a thumb.

An extraction cleaning machine has a solution dispensing system and a recovery system for applying a cleaning solution to a surface and recovering the solution from the surface, and an agitation brush assembly for agitating the surface. The agitation brush assembly can include friction-type or other dampers for reducing brush bounce, and biasing elements for maintaining a constant downward force on the brush. The brush can have multiple helical rows of tufted bristles, preferably at least four rows, or can comprise a continuous helix of bristles in a twisted-wire spindle. The brush can further have a removable fabric cover for mounting over a bristle brush for contacting a surface being cleaned. The brush assembly can function in an upright extraction cleaning machine with or without an above floor cleaning tool, a hand-held extractor, or a hand-held attachment to a canister extractor or an above floor tool in upright extractor.
摘要:
The present disclosure relates to Moraxella catarrhalis outer membrane vesicle (OMV) compositions, to selected antigenic proteins from the outer membranes of M. catarrhalis which have a variety of useful properties, and to monoclonal antibodies against these proteins. Particular "Outer Membrane Proteins" (OMPs) of the invention are characterized as having molecular weights of about 30 kD, 80 kD (also termed CopB protein) and between about 200 and 700 kD (HMWP antigen). Passive immunization with monoclonal antibodies directed against these proteins confers protection against homologous and heterologous Moraxella catarrhalis strains in animal models, and active immunization with outer membrane vesicles also enhances pulmonary clearance of distinct M. catarrhalis strains. This demonstrates both the utility of antibodies in conferring passive immunity and the usefulness of OMPs, or variants thereof, in the preparation of vaccines. Also disclosed are DNA segments encoding these OMPs, methods for preparing the antigens, or variants, through the application of recombinant DNA techniques, as well as diagnostic methods and related embodiments.
