Patent number: 6742334Abstract: A speed regulation jack comprises at least one input cylinder and one output cylinder, and parallel hydraulic lines between the input and output cylinders. A differential oil circuit is connected between the inlet cavity and the return cavity of the output cylinder, and a control valve is connected in series between the return cavity of the output cylinder and the oil tank, and this control valve controls the return oil of the return cavity. This speed regulation jack takes the magnitude of the load as its signal and transfers automatically between different lifting speeds, thus enhancing the lifting efficiency of the jack.Type: GrantFiled: October 22, 2002Date of Patent: June 1, 2004Inventor: Qun Fan

Patent number: 6742335Abstract: EGR mass fraction or a value indicative thereof can be calculated based on temperature measurements rather than mass flow and/or pressure measurements, hence negating the need for expensive and relatively unreliable measurement devices in an active EGR system for an internal combustion engine. The EGR system may be a low pressure EGR system configured to direct cooled, filtered EGR to the engine's air intake system using an effective, simple venturi and/or a continuously regenerated catalytic particulate trap. The resultant system can reduce NOx emissions in a diesel engine on the order of 50% and approximately 90% for CO, HC, and PM. NOx and other emissions can be reduced still further when the EGR system is combined with other pretreatment and/or after treatment devices. Many components of the low pressure EGR system are also usable in a passive EGR system.Type: GrantFiled: July 11, 2002Date of Patent: June 1, 2004Assignee: Clean Air Power, Inc.Inventors: N. John Beck, Hoi Ching Wong, Kresimir Gebert

Patent number: 6742340Abstract: This invention is a fuel injection control system for a turbine engine. The invention uses at least one fuel injector, having means for injecting fuel in pulses to the combustion chamber of a turbine engine, and an electronic control unit to receive and interpret input sensor signals from selected operating functions of the engine and to generate and direct fuel injection signals to modify the pulse duration and/or frequency of fuel injection in response to a deviation from a selected operating function, such as the desired operating speed, caused by variable operating loads encountered by the turbine engine. This configuration provides significantly greater fuel efficiency, better operational control and response time, and a lighter weight than is currently available in turbine engines.

Patent number: 6742341Abstract: A method of controlling a gas turbine engine to provide protection against damaging pressure transients in the combustion process and to ensure compliance with emission requirements. Pressure fluctuations are monitored in a plurality of frequency ranges, and unacceptable pressure transients in different frequency ranges trigger different corrective actions.

Patent number: 6742347Abstract: A feedforward control method for an absorption chiller includes determining the disturbance transfer function, determining the capacity valve transfer function, measuring the actual disturbance, and implementing the feedforward control function in a feedforward controller. The feedforward control function is represented by the ratio of the disturbance transfer function divided by the capacity valve transfer function. The disturbance transfer function and the capacity valve transfer function are measured by applying a known amplitude input perturbation to the disturbance or capacity valve and recording the resulting perturbation in the output leaving chilled water temp. The disturbance transfer function is then the ratio of the delta leaving chilled water temperature divided by the delta change in the disturbance. The capacity transfer function is the ratio of the delta leaving chilled water temperature divided by the delta change in the capacity valve.Type: GrantFiled: January 7, 2003Date of Patent: June 1, 2004Assignee: Carrier CorporationInventors: Richard Kolk, David M.

Patent number: 6742348Abstract: Disclosed is a method for controlling the aperture ratio of a linear expansion valve (LEV) so as to control the flow rate of refrigerant circulating in an air conditioning system. The LEV aperture ratio is controlled to range from the minimum value to the maximum value, which are determined according to the compressor's capacity and the cooling and heating modes. The LEV aperture ratio is controlled also based on the compressor's operating status, the change of the indoor fan's air volume, and whether or not the indoor fan operates. Such LEV control enables refrigerant to always be circulated at a suitable flow rate, improving the cooling and heating efficiencies, and also prevents liquid refrigerant from flowing into the compressor, securing high reliability of the compressor.Type: GrantFiled: March 4, 2003Date of Patent: June 1, 2004Assignee: LG Electronics Inc.Inventors: Min Ho So, Won Hee Lee, Chang Min Choi, Yoon Jei Hwang, Deok Huh, Cheol Min Kim

The V-block press material has a sectional view including an outer portion of about uniform width and a tapered inner portion with a slant gently inclined toward an innermost end of the material from a place distant from a rocking edge by a predetermined distance inward. The main punch and the counter punch have front shapes of the substantially same as that of the V-block, and either punch facing the rocking edge has a slant starting at a place corresponding to the rocking edge and extending inward rising gradually.Type: GrantFiled: October 31, 2001Date of Patent: June 1, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Hiroshi Wakui

Patent number: 6742374Abstract: A method is disclosed for partly reinforcing a workpiece which is capable of reinforcing the reinforcement requiring part of the workpiece on which stress is liable to be concentrated upon use of the workpiece. A workpiece 1 made of metal having a reinforcement requiring part 10 and a forming die 3 are provided. The reinforcement requiring part 10 of the workpiece 1 is heated up to a higher temperature than the other part 18. The reinforcement-requiring part 10 is quenched and reinforced as compared to the other part 18 by bringing the forming surface area of the forming die 3 into direct contact with at least the reinforcement-requiring part 10 of the workpiece 1 which is then strongly pressed.Type: GrantFiled: February 19, 2002Date of Patent: June 1, 2004Inventor: Masashi Ozawa

Patent number: 6742376Abstract: A compound indenter for metal coldwork, and a method of employing such tooling. The compound indenter tool is used to produce deformation in a workpiece structure, to provide a selected beneficial residual stress profile in the workpiece, in order to provide high fatigue life structures in a minimum number of manufacturing steps. Preferably, action of a compound indenter causes deformation of the workpiece, causing dimples in the workpiece. By optimized use of the method, a relatively uniform beneficial residual stress profile is provided at both the surface and at the midplane apertures in a workpiece, so as to improve overall fatigue life. An improved, compound indenter tool profile shape is described, having a first, elongate indenter with a shaped indenter surface portion, and a second shaped indenter surrounding the first indenter and forming an annular shoulder recessed from the surface portion of the first indenter.Type: GrantFiled: February 9, 2001Date of Patent: June 1, 2004Assignee: Stresswave, Inc.Inventors: Eric T. Easterbrook, Nils Juhlin

Patent number: 6742377Abstract: A passive-adaptive indentor is provided for cold working a material that includes a material surface and a depth extending in a direction that is perpendicular to a direction of the material surface. The passive-adaptive indentor has a first member that includes a first working end that is configured to create a first residual stress field that extends to a predetermined depth in the material. The passive-adaptive indentor also has a second member that includes a second working end that is configured to create a second residual stress field that extends to a generally fixed second depth of the material regardless of the depth to which the first residual stress field extends. A method of using a passive-adaptive indentor for cold working a material is also presented.Type: GrantFiled: June 13, 2002Date of Patent: June 1, 2004Assignee: The Boeing CompanyInventors: Mark A. Woods, Jeffrey A. Wilkerson
