US Patent:

55666264, Oct 22, 1996

Filed:

Dec 12, 1994

Appl. No.:

8/353670

Inventors:

Walter R. Schaefer - Cherry Hill NJ
Eustathios Vassiliou - Newark DE
Bruno R. Kuhn - Nassau Bay TX
Joseph F. Guinto - Pitman NJ

Assignee:

Rollins Environmental Services, Inc. - Wilmington DE

International Classification:

A47J 3600

US Classification:

110246

Abstract:

An incineration kiln of the slagging mode, which has an outer shell and a protective layer inside the shell with quantum failure identifiers. The quantum failure identifiers recognizes one or more stages of increasing degree of failure of the protective layer, so that an operator may be warned and take suitable measures to protect further deterioration of the protective layer and restore the same.

Assignee:

Rollins Environmental Services, Inc. - Wilmington DE

International Classification:

F23G 700

US Classification:

110346

Abstract:

Methods and apparatuses are presented for incinerating waste in increments in a controlled and efficient manner, based on an arbitrary factor labeled Relative Power Factor. Also, presented are methods and apparatuses for determining the Relative Power Factor. The Relative Power Factor is defined as the ratio of the maximum difference in temperatures recorded at a point in the combustion effluent stream and at a point in the hot gaseous stream prior to combustion to the time interval between ignition of the waste and the achievement of the maximum temperature difference.

International Classification:

H04J 308

US Classification:

178 73

Abstract:

A subscriber at a remote location is provided the capability of configuring a multipoint private line network composed of multipoint junction units or hubs that provide alternative functions of permitting exclusive data intercommunication between main lines thereof and selected branch lines thereof when certain selection codes are applied to the main lines without the subscriber having knowledge of the selection codes or the network "mapping". The subscriber at the remote location sends a service request defining the function desired and the ultimate downstream terminal to be interconnected or blocked and a control unit in the network consults a network map to identify the upstream and downstream branch lines to be selected, sending a sequence of selection codes to first select the upstream branch and then select the downstream branch or branches. The control unit also monitors responses of the junction units and reports results to the control location.
