摘要:
A process for dyeing keratinous fibers comprises a two-step operation in which in the first step the fibers are contacted with an indole dye in a medium suitable for dyeing the fibers, the medium being free from any oxidation catalyst and oxidation catalyst. Thereafter, in the second step the fibers are contacted with a para type oxidation dye precursor in a medium which is also suitable for dyeing the fibers and is free from any oxidation catalyst and oxidation agent. A multi-compartment kit housing the indole dye and para type oxidation dye precursor is also provided.

A dispenser having a reciprocating pump to feed a liquid product to a mixing chamber and an air pump with a piston to simultaneously compress and feed compressed air to the mixing chamber. The body containing the mixing chamber is mounted on the product pump and the air piston is mounted on the body. Manual pressure on the air piston is transmitted to the body which moves down to cause the product pump to reciprocate. The product pump includes a chamber with a valve which opens only after the pressure in the chamber exceeds a certain value. The air pump includes a valve which opens only after the air pressure exceeds a certain value. The air pressure valve is selected to open at the same time as the pump valve opens so that the product is dispensed as a spray.
摘要:
A mechanism for declarative service domain federation uses a declarative approach to both the visibility aspect and the management aspect of service domain federation. Instead of manually exporting services, that is, selecting individual services from source domains to be visible in the target domain, using the present system, a federation architect uses a federation console to specify federation intent. The federation intent may include federation rule, query-based service group, and quality-of-service (QoS) policy. Based on the declared federation intent, a planning engine resolves the individual services based on the group query, generates the service visibility configuration, and creates the necessary service proxies and/or mediation objects to satisfy the goal. At runtime, a service monitor collects the performance metrics of federated services and dynamically adjusts the mediation/proxy configurations to maintain the QoS objectives specified by the federation architect.
摘要:
A system for providing flight accident insurance at low price and fixed coverage comprises means for limiting the number of policies that can be sold on any given flight to not more than a predetermined number. The predetermined number may be 20. The system comprises an input device for receiving information from a traveler and an output device for providing an insurance quote to said traveler.

摘要:
A method for deriving a set of efficient path costs for a group of nodes comprising a source node and a plurality of destination nodes in a data communications networks, wherein the path costs for paths between nodes in the group are defined in the network and each path cost comprises a restrictive cost and an additive cost, comprises iteratively identifying the paths of higher bandwidth first and, when two or more paths of equal bandwidth are encountered, selecting the path having a lower transit delay associated therewith.

Device for the compression and storage of air comprising, on the one hand, a reservoir (1) provided with an air discharge head (5) intended for cooperation with a container to be charged with compressed air and, on the other hand, at least one compression chamber (C1), associated with air inlet valves (19) and air ejection valves (15) and with a compression element actuated by a motor means (13) compressing the volume of the chamber (C1) between a maximum volume and a minimum volume, the ratio between the maximum volume and the minimum volume of the said chamber (C1) being from 1.2 to 20.
摘要:
A superheated vapor generator including a porous material substantially filling an annular space between two concentric spaced apart tubular inner and outer electrodes connected across a power source. A pump is provided to pump a predetermined quantity of liquid into the porous material to temporarily complete the circuit through the electrodes and generate superheated vapor or steam. Since the liquid itself completes the circuit, no switches or controls are required. Labyrinthe passages between the pump and the inlet to the annular space and between the interior surface of the inner electrode and a tubular steam discharge outlet prevents dangerous current leakage and assure generation of superheated vapor. An electrically grounded porous metal plug in the vapor outlet minimizes electrical shock hazards. The vapor generator is held in the hand and can be used for setting or treating human hair.
