6462555, Oct 8, 2002

Filed:

May 7, 2001

Appl. No.:

09/850871

Inventors:

John S. Schaefer - Austin TX 78758

International Classification:

G01R 3100

US Classification:

324508

Abstract:

A self-contained unit intended primarily for tracing the circuit connection between an electrical outlet or lighting receptacle and its corresponding circuit-breaker. The preferred embodiment includes a housing, a male three prong electrical plug, a sound-producing means, a first momentary switch which permits testing of a ground fault interrupt across either a hot wire and a neutral, or across a hot wire and the ground; and a second momentary switch which permits testing of reverse polarity by testing across a neutral and the ground. An alternate embodiment incorporates a single 3-way switch. Adapters are used to temporarily adapt bare wires or a lighting receptacle to a female plug so that the device may be used.

Assignee:

TA Instruments, Inc. - New Castle DE

International Classification:

G01N 100

US Classification:

374 12, 374 32, 374 33, 374 31, 374 10

Abstract:

An improved differential thermal analysis/differential scanning calorimetry (collectively, DSC) assembly with a furnace block assembly having a measurement chamber and a furnace heater. The measurement chamber has a sensor assembly for receiving a sample material and a reference material. The furnace block assembly is coupled to a generally cylindrical cooling flange through a distributed thermal resistor that allows a constrained heat flow between the furnace assembly and cooling flange. The thermal resistor can also withstand the mechanical stresses associated with the differential expansion and contraction of the furnace assembly and cooling flange without permanent deformation of the thermal resistor. The cooling flange can be coupled to various cooling devices, permitting operation of the overall DSC instrument in a variety of temperature regimes for a variety of applications.

International Classification:

G01N 25/00
G01K 13/00

US Classification:

374 14, 374141, 374208, 436908, 236 44 C

Abstract:

Systems and methods for minimizing extraneous forces and calculating corrected weights of samples based on buoyancy factors for a thermogravimetric analyzer (TGA). The TGA includes a balance chamber and a furnace configured to heat a sample. A null balance is provided in the balance chamber and is used to measure the sample weight change during heating. The furnace includes a cylinder open at the top to receive a sample. The bottom of the cylinder is closed except for a small hole that allows a thermocouple to pass through. An infrared heat source may be provided to heat the cylinder. The balance chamber can be thermally isolated from the furnace using an actively cooled plate and a system of heat shields disposed between the furnace and balance chamber. A thermocouple disk is further provided to limit gas flow in the furnace and increase reliability of sample weight measurements.

International Classification:

G06F 17/30

US Classification:

707803

Abstract:

Systems and methods consistent with the invention may include generating, using a processor of the computer system, a definition file of a first format for the data object, generating a database table, generating a mapping between the definition file and the database table, linking the definition file to a data source by including a path of the data source in the definition file, the data source including an attribute, executing, using the processor, a query to extract the attribute from the data source, importing the extracted attribute into the database table using the mapping between the definition file and the database table, and storing, in the memory device, the definition file, the database table, and the attribute for generation of the data object with the attribute.
