摘要:
Disclosed is a system for controlling appliances of at least one building, each appliance being associated with a local controller and having a control input and at least one control point. The system includes a central processor computer having an operator interface and an equipment interface, a network connected to the equipment interface and having a plurality of nodes for communicating with each of the appliances, a log file being stored with respective area, description, and address fields containing corresponding data of the control points. A control program in the computer feeds the equipment interface to drive the control inputs of the appliances in response to a database, the database being populated from a tagname dictionary. A conversion program produces the tagname dictionary as a transfer file, the program including instructions for accessing the area, description, and address fields of the log file, generating for each point a tagname as a concatenation of the area and description fields, and an item including contents of the address field, and storing the tagnames and associated items with the header in the transfer file, whereby the system drives the control inputs of the appliances in response to the control point data of the log file. The conversion program can include a mode selector for directing conditional, unconditional and test modes of a utility process populating the database. Also disclosed is a process for controlling multiple appliances of at least one building.
摘要:
A method and apparatus for creating density images of an object through the 3-dimensional tracking of protons that have passed through the object are provided. More specifically, the 3-dimensional tracking of the protons is accomplished by gathering and analyzing images of the ionization tracks of the protons in a closely packed stack of scintillating fibers.

There is disclosed an airplane seat having a base member provided with a pair of tracks located on the bottom thereof which cooperate with a pair of tracks located on the floor of an airplane fuselage and which moves in a fore and aft direction. Located above the base member is an adjustable seat base and adjustable back member pivotally joined thereto. The seat base is connected through a shaft which cooperates with a clutch located in an opening in the top of the base and which permits universal movement of the seat base in fore, aft and lateral directions independently of the movement of the base member in a fore and aft direction. The seat is provided with a pair of adjustable arm rests, as well as being provided with adjusting linkage to raise and lower the leading edge of the seat base and the curvature of the front surface of the back member and linkage for adjusting the vertical position of the back member with respect to its relationship with the seat base, and the necessary controls for carrying out the various adjustments located on the arm rests.
摘要:
A distillative separation of carbon dioxide and hydrogen sulfide is improved by adding a C.sub.3 -C.sub.6 alkane, a mixture of C.sub.3 -C.sub.6 alkanes, SO.sub.2 or SO.sub.3 to a distillation column to increase the relative volatility of carbon dioxide to hydrogen sulfide. Increasing the relative volatility facilitates the separation.
