摘要:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing decision models. In one aspect, a method includes providing data that cause presentation of a model development user interface receiving first model rule data through the user interface. The first model rule data specify a first characteristic of a violating resource and a threshold score for the first characteristic. Additional model rule data are received through the user interface. The additional model rule data specify one or more additional model rules. Relationship data are received through the user interface for each of the additional model rules. The relationship data specify sets of the additional model rules that violating resources satisfy. Data that cause a hierarchical presentation of the first model rule and the additional model rules are provided.

A method and apparatus for sealing the gap between adjacent boiler tubes of a panel wall thereby making the panel wall air-tight. First and second sealing members are secured to opposite sides of adjacent boiler tubes thereby defining a gap therebetween. This gap is then filled with a metal salt solution which is dried in place so as to leave a residue behind. Subsequently, this residue is further heated which converts it to a metal oxide that forms an air-tight ceramic plug. This plug possesses properties which make it resistant to deterioration once the panel wall goes into service.

According to the invention, a pre-conditioning method of operating an autoclave during a pre-conditioning stage of a sterilisation cycle wherein the autoclave has a chamber having an external wall, a supply of steam, a heater to heat the external wall of the chamber and a vacuum pump, which comprises the steps of: applying a first vacuum pulse in the chamber; heating the chamber; supplying steam to the chamber at a pressure above atmospheric pressure for a holding period which is sufficiently long for the contents of the chamber to be heated; and applying a second vacuum pulse in the chamber; has been found to be effective as a pre-conditioning stage for a sterilisation cycle for sterilising a porous load.
摘要:
A method of providing boiler tubes with a variably ribbed interior surface. A suitably dimensioned spindle with a channel having a desired pattern on the exterior surface of the spindle is wrapped by a wire-like member in the channel so as to form thereon a reverse image of the desired, patterned tube ribbing. A brazing metal paste is applied on the exterior surface of the wire-like member and the spindle is inserted into a tube to be ribbed. The wire-like member is released from the spindle to allow the wire-like member to conform to the inner surface of the tube, and the tube is heated to the melting temperature of the brazing metal paste so that the wire-like member bonds to the inner surface of the tube, and the metal tube is then cooled.
