Filed: 1997-10-07
Abstract: A printed circuit board test fixture includes a plurality of flexible printed circuits having circuit traces on one side for interconnecting the test probe pin assemblies of the fixture with the interface connector pins for the interface panel of the fixture. The flexible circuits are folded in the fixture housing to provide spaced apart non-contacting layers of first contact areas for connection to the test probe pin assemblies and spaced apart non-contacting layers of second contact areas for connection to the interface connector pins. The layers of flexible circuit of each contact area receive the test probe pin assemblies and interface connector pins which secure the layers of flexible circuit in the fixture. The test probe pin assemblies and the interface connector pins make electrical and mechanical engagement with terminal apertures in the layers of flexible circuit. The layers further include through holes allowing the test probe pin assemblies and interface connector pins to pass through layers of the flexible circuit without making electrical contact with these layers. This permits circuit traces to be used on each of the layers of flexible circuit for selected test probe pin assembly and interface connector pin connected pairs.

Title: Method of venting a furnace
Inventor: WATERMAN TIMOTHY
IPC: F23L17/00
Filed: 1998-02-09
Abstract: An improved furnace is provided which can be field modified to change the pressure drop across the inducer. The pressure drop is modified to accommodate vertical or horizontal venting and adequately lined and inadequately lined chimneys. A first rate of flow of combustion byproducts into the vent system is used when the chimney is adequately lined and a second relatively higher rate of flow is used when the chimney is inadequately lined. The rate of flow is changed by inserting or removing an obstruction in the flow of combustion byproducts. The obstruction could be a tab or choke placed at the inducer outlet or a similar device in the inducer inlet. When the tab is in place the flow of combustion byproducts is reduced. When the tab is removed, the flow rate increases. Alternatively, the inducer inlet could be adjusted to increase or decrease the amount of air flow through the inducer.

Title: A process and apparatus for tracing software entities in a distributed system
Inventor: DIEC MICHAEL
IPC: G06F11/36
Filed: 1998-07-28
Abstract: The invention relates to a process and apparatus for tracing software entities, more particularly a tracing tool providing   tracing   capabilities   to   entities   in   an application.    The  object-tracing  tool  provides  software components   to   allow   tracing   the   execution   of   an application.  Tracing  software  entities  is  important  for software  developers  to  permit  the  quick  localization of errors and hence facilitate the debugging process.   It is also useful for the software user who wishes to view the control  flow  and perhaps  add  some  modifications  to  the software.   Traditionally, software-tracing tools have been confined to single node systems where all the components of an application run on a single machine.   The novel tracing tool presented in this application provides a method and an apparatus  for tracing software entities  in a distributed computing environment.   This  is done by using a network management  entity to  keep  track of  the  location of  the entities in the system and by using a library of modules that can be inherited to provide tracing capabilities.   It also uses a log file to allow the program developer or user to  examine  the  flow,  the occurrence  of  events  during  a trace  and  the  values  of  designated  attributes.   The invention also provides a computer readable storage medium containing a program element to direct  a processor of a computer to implement the software tracing process.
