摘要:
A method of forming a vehicle component, particularly an elongated impact beam, having an open section structure, in a manner to provide predetermined strategically strengthened portions, comprising the steps of cold forming unhardened steel into a workpiece having mounting surfaces, selectively fixturing the mounting surfaces, static induction heating the workpiece with lengthwise surface eddy currents on selected portions, followed by quenching of the fixtured heated workpiece to form strengthened portions, and unfixturing the resulting component. Also disclosed is apparatus to accomplish this, and the resulting novel vehicle component.

A gas-fired burner including a cylindrical burner housing having a premixed fuel/air opening. Disposed within the cylindrical burner housing is a cylindrical burner ring which forms at least one row of a plurality of burner ports. The cylindrical burner ring is sized relative to the burner housing such that an annular space is formed between the burner housing and the burner ring. Upper and lower annular rings extend between the burner ring and the burner housing, thereby enclosing the annular space. Disposed within the burner ring is a secondary air flow restrictor for controlling the flow of secondary air to the flame. A multi-finger grate having alternating long and short fingers is disposed above the burner housing.

A method for testing computer software is described. The method is intended for operation on software which may or may not have been previously subjected to unit and integration tests, to determine if it will meet the specific requirements of an end user. The method is applicable to internally developed, contractor developed, or vendor supplied software. The method includes application in six key process areas. The six key process areas are development of a test plan, development of test cases to support the plan, development of an environment to simulate the technical environment in which the program will operate, test execution in which the tests are executed in a technical environment, compiling and analyzing the results and finally reporting the results in a form whereby the end user can determine both the feasibility of the software system for the specific requirements and any areas where additional testing or modifications are necessary.

Some embodiments of the invention relate to a system and method for enhanced monitoring and/or controlling a flow of a media. For example, the flow of the media may be controlled and/or monitored over an enhanced range of flow rates; control over the flow of the media may be highly linear; the flow of an aggressive media may be controlled and/or monitored; or, other advantages may be provided.

A method is disclosed for operating a gas-fired heater to maintain temperature within a zone. The gas-fired heater is modulated between a higher firing rate and a lower firing rate within a pseudo steady-state mode until a current firing rate exceeds a predetermined maximum time period ttrans. The gas-fired heater is then modulated between an updated higher firing rate and an updated lower firing rate within a transient mode until an updated current firing rate exceeds a predetermined maximum time period tdiag. Finally, the higher firing rate and the lower firing rate are redefined in a diagnostic mode until the gas-fired heater returns to the pseudo steady-state mode.
摘要:
The invention is a piezoelectric self-cleaning apparatus, such as a chemical injection pump. The chemical injection pump is self-cleaning by employing either as an integral part or as an added part, a piezoelectric component that implosively cleans the pump head. This invention involves a liquid delivery system made of a liquid processing path and a piezoelectric actuator connected to or integral with said liquid processing path to enhance removal of unwanted solids from the liquid processing path or to maintain a blend, mix and/or integrity of a liquid chemical, wherein the liquid chemical does not precipitate particles, crystallize, separate or come out of solution.

摘要:
A sign with an interchangeable magnetic display. The sign comprising at least one panel, a display, a base, and a brace which limits relative motion between the panel and base. The panels form a ferromagnetic support surface which is attracted to a mounting surface of the display that is magnetic, the display thereby being easily attachable and detachable from the support surface. The base having a clamp used to attach the panels to business equipment, such as an exterior menu stand in a restaurant's traffic corridor, without damage to the stand.

A table attachable to the tailgate of a vehicle extends from the tailgate. The table is foldable between a stowed and a deployed configuration. In the stowed configuration the table can be folded against the vehicle tailgate or extend transverse to the tailgate and securable to the vehicle. In the deployed configuration the table when extended in the plane of the tailgate forms a surface.
