  • Publication number: 20150339619
    Abstract: A computer-implemented method for automatically updating work schedules includes distributing a first plurality of work schedules to a work crew. The method further includes receiving productivity updates from the work crew, the productivity updates indicative of an actual amount of work accomplished by the work crew in the first time period, and, based on one or more differences between the actual amount of work and the estimated amount of work, updating the one or more initial estimates of productivity. Still further, the method includes causing a schedule generator to generate a second plurality of work schedules based on the one or more updated estimates of productivity, and distributing the second plurality of work schedules to the work crew.

  • Publication number: 20130125705
    Abstract: The present document describes a method and confinement unit for stopping a chemical reaction involving hot metal dross and a gas in the surrounding environment. The method comprises transferring the hot metal dross in a dross pan and placing the dross pan with the metal dross therein in the gastight chamber. Then, the dross pan is sealed with the hot metal dross therein into a gastight chamber of a fixed interior volume. The chemical reaction occurring inside the gastight chamber depletes a limited amount of gas present inside the gastight chamber, thereby stopping once the gas is completely depleted. The gastight chamber is shaped and sealed to withstand a pressure differential created by the depleting of the gas in the fixed interior volume, until the hot dross is cooled and the chemical reaction has stopped.

  • Publication number: 20050033926
    Abstract: Under the present invention, when a request for a web page is received from a client on a server, the web page is built and analyzed for cacheablity. If the web page is cacheable, an entity tag is generated. The entity tag generally identifies the various sources of dynamic content in the web page, and includes cacheability flags and time values associated with the dependencies. The entity tag is sent to the client with the web page where it is stored in local cache memory. If a subsequent request for the same web page is issued from the client, the request is accompanied with the entity tag (e.g., in a header). The entity tag is decoded and analyzed by the server to determine whether the cached web page is still valid.

  • Publication number: 20020108968
    Abstract: A dispensing bottle which stores two separated fluids and blends the fluids when dispensing. The bottle has two liquid receptacles and a cap which threads to the bottle. The receptacles include the open interior of the bottle, and an interior vessel separate and removable from the bottle. The cap includes a mixing circuit which retrieves and blends fluids taken from the receptacles. The mixing circuit includes a pick-up tube to each receptacle, coaxially aligned, one within the other, a mixing chamber and a check valve preventing backflow of mixed fluids into the storage receptacles. A proportioning valve adjusts the proportions of the fluids entering the mixing chamber. The bottle has a plunger type pump which propels mixed fluid to a discharge nozzle. The pump optionally has mixing blades projecting therefrom and/or mixing balls therein for blending the fluids.

  • Patent number: 6269979
    Abstract: A multi-compartmented storage and dispensing container is disclosed. In the preferred embodiment, the larger outer bottle surrounds and is attached to an inner compartment or chamber that, in the preferred embodiment, is a generally cylindrical enclosure having helically oriented scores or striations. This cylindrical inner enclosure is attached at its base to the outer bottle and is engaged and broken open by the closure assembly. The closure assembly consists of a threaded cap attached to an inner enclosure engagement arm. A removable security ring is initially located between the bottom of the threaded cap and the outer bottle shoulder. After this ring is removed, the user tightens the cap all the way down, bringing the inner enclosure engagement arm into contact with anchored cylindrical inner enclosure. As the cap is twisted, the inner enclosure breaks along the scored lines due to the torque, and the material contained within the inner enclosure is released into the outer bottle.
