摘要:
Described are methods, systems, and apparatus, including computer program products for managing a hierarchy of modules. A user can select a first hierarchy or a second hierarchy, where the first hierarchy includes a module and a first sub-module. The module is associated with a component and the first sub-module is associated with a first sub-component of the component. The module is associated with the first sub-module using a first hierarchical reference of a first type. The second hierarchy includes the module and a second sub-module, where the second sub-module is associated with the first sub-component. The module is associated with the second sub-module using a second hierarchical reference of a second type that is different from the first type.
摘要:
An aerosol generating device includes a housing, a heater and an optional mouthpiece. The heater volatilizes liquid within a flow passage and forms an aerosol in the mouthpiece. An aerosol confinement sleeve is disposed to control the size distribution of the aerosol.

A demountable hanger assembly, for mounting at various locations in a display panel, has a cylindrical socket of predetermined diameter, a magnet mounted within the socket; a hanger locating device mounted within the socket adjacent to the magnet; a hanger member having a cylindrical portion to make a snug sliding fit in the socket, the cylindrical portion at least being formed of a magnetically sensitive material, attracted to the magnet, a locating recess formed in the cylindrical member to interfit with the locating member in the socket; and a hanger extending outwardly from the cylindrical portion, the hanger member being demountable from and mountable in the socket by manually separating the cylindrical member from the magnet.
摘要:
A process for the manufacture of a compound of formula (V), useful for making rosuvastatin, by a stereoselective aldol reaction is described. Novel intermediates and processes to make them are also described.
摘要:
A hydroxycarboxylic acid copolyester of R-stereospecific configuration contains a majority of first repeating units capable of forming a highly crystalline high-melting homopolyester and a minority of second repeating units capable when randomly copolycondensed with said first repeating units of lowering the melting point of said homopolyester and is characterised by one or more of: higher crystalline melting point, shorter crystallising time, higher notched impact strength at age 1 month, as compared with corresponding random polyester, and said majority repeating units in the polyester chain being present in blocks longer than correspond to their over-all molar proportionality. The copolyester may be made by fermentation, controlling the distribution of repeating units by reference to the pattern of feeding substrates corresponding to the respective repeating units.
摘要:
Disclosed is a gravity flow spool valve for dispensing small volumes of liquid. The valve comprises an elongated hollow housing and a piston adapted to move within the interior of the housing. The piston has a first and second spool, spaced from each other using a coupling rod. The piston is coupled to an activation button which moves the piston from a dispense position to an intake position. In the intake position, the second spool is moved past a series of intake holes in the housing and fluid surrounding the holes flows into the chamber defined between the interior surface of the housing, the first spool and the second spool. When in the dispense position, the chamber is in communication with a spout and a ventilation hole which allows the fluid contained within the chamber to flow out the spout. One application of the valve is dispensing perfume samples.

摘要:
An aircraft engine mounting structure comprising a pylon box having an upper surface and at least one attachment element configured to be attached to a front spar of an aircraft wing box, the front spar having a lower surface, the attachment element being configured to attach the rear face of the pylon box to the front spar such that at least a portion of the upper surface of the pylon box lies above the lower surface of the front spar.
摘要:
An aerosol generator includes a flow passage having an inlet end, an outlet end, and a constriction in the flow passage at the outlet end. A heater is operable to heat liquid in the flow passage to produce a vapor, which is expelled from the outlet end of the flow passage.
