  • Publication number: 20240280031
    Abstract: A gas (or steam) turbine is disclosed including: a rotor with at least one array of rotor blades, a stator with a casing and a shroud ring; the shroud ring extends around the array of blades rotor and the casing extends around the shroud ring. The shroud ring has radial size independent from temperature thanks to its material, and is movably coupled with the casing so to allow the casing of the stator to thermally expand and contract during operation of the turbine while maintaining the shroud ring radial size. Also the rotor thermally expands and contracts during operation of the turbine, and, at working temperature, tip regions of the rotor blades are in close proximity to an inner region of the shroud ring so that clearance is small or even zero at working condition.

  • Patent number: 11958713
    Abstract: A sheet processing device has a moveable beam (36) that moves in the vertical direction, a gripper bar (30) for gripping a sheet that travels through the sheet processing device (10), and a gripper bar locking device (40) that can lock the gripper bar (30) in a precise position. The gripper bar locking device (40) has a locking lever (68) that is pivoting between a rest position and a locking position. The locking lever (68) is connected to a vertical linear guide coupled with the moveable beam (36) resulting in a precise, compact and simple system to lock the gripper bar.

  • Patent number: 11904596
    Abstract: A hot foil stamping press has a pressing system for pressing a foil onto a sheet, a blow unit which is positioned at a distance to the pressing system for directing a stream of gas between the sheet and the foil. The stream of gas to detaches the foil from the sheet after each stamping cycle. A gripper bar is arranged between the blow unit and the pressing system for gripping the sheet. A flow guiding element is arranged between the blow unit and the pressing system, preferably on the gripper bar, for directing the gas from the blow unit between the sheet and the foil. Said element avoids the losses in the stream of gas due to the aperture that exist between the grippers in a typical gripper bar.

  • Patent number: 11691410
    Abstract: A hot foil stamping press (10) comprises a platen press (16), with a supporting plate (22) comprising a base plate (26) and a compensating plate (28) being rotatably attached to the base plate (26) for switching between an operating position and a makeready position and a hook element (38) comprising a base part and a top part being arranged at an angle relative to the base part. The hook element (38) is rotatably attached to a door (30) of the platen press (16) by a fixation axle for switching between a releasing position and a securing position of the hook element, wherein the top part retains the compensating plate (28) in its makeready position when the hook element (38) is in its securing position.

  • Patent number: 9790791
    Abstract: External combustion engine which comprises a first cylinder and a second cylinder, in which a first piston and a second piston are able to slide respectively. The first and second cylinder are fluidically connected with respect to each other for the passage of a heat-carrying fluid suitable to determine the cyclical movement of the first piston and the second piston. The external combustion engine also comprises a drive shaft rotating around an axis of rotation, and with which crank means are solidly associated, provided with at least a first pin and a second pin having pivoting axes parallel to each other, and also disposed distanced radially from the axis of rotation. The external combustion engine also comprises first and second kinematic connection means suitable to connect respectively the first pin and the second pin to the first piston and respectively to the second piston.

  • Patent number: 7711660
    Abstract: In a system and method for processing data, a user interface enables a user to enter mapping data to enable incoming data to be converted to a common data format. A database stores the mapping data and data quality rules, and a receiver receives data from a data source. The processor applies the data quality rules to the common format data to identify any potential errors in the common format data and notifies the user of any potential errors found in the common format data. The data rules may include data structure rules and/or data trending requirements based upon data trends or norms. The data source may be an employer, insurance company or other entity. The data may include insurance claim data, medical data and/or prescription data and/or eligibility and/or occupational and non-occupational data.

  • Publication number: 20080014091
    Abstract: A method is provided for determining a blade topology that reduces the effects of vibratory stress on a turbomachine blade having a plurality of discrete locations, wherein each discrete location has a thickness. The method includes the steps of creating a computational model of the blade, using the computational model to modify the thickness of at least one of the discrete locations a predetermined amount, determining a combination of a discrete location and predetermined thickness amount that reduces vibratory stress on the blade, and applying the determined combination to the computational model to create a revised blade. A turbomachine including a blade having the determined blade topology is also provided.

  • Publication number: 20060257253
    Abstract: A shroud is provided for separating an air turbine starter housing from a turbine wheel. The shroud comprises a ring and a bumper. The ring is configured to be disposed between the turbine wheel and the housing and has an outer peripheral surface and an inner peripheral surface that defines a flow channel. The bumper is coupled to and extends radially inwardly from the ring inner peripheral surface and defines a bumper section of the ring flow channel. At least a portion of the bumper section has a cross-sectional flow area that is less than another cross sectional flow area of the ring flow channel.
