Patent number: 11946462Abstract: Hydraulic axial piston unit having a rotational group for driving or being driven by a driving shaft, and a tiltable displacement element for adjusting the displacement volume of the rotational group. The rotational group includes a rotatable cylinder block in which working pistons are mounted reciprocally moveable in cylinder bores for conveying hydraulic fluid from an inlet port to an outlet port on a valve segment. At least two control ports are located on the valve segment each between the inlet port and the outlet port. The control ports can be brought sequentially in fluid connection with the cylinder bores when the cylinder block is rotating. At least one hydraulic fluid injector is connected fluidly to one control port, for sequentially injecting pressurized hydraulic fluid via the control port into the passing cylinder bores. Via the other control port hydraulic fluid can be drained from passing cylinder bores.Type: GrantFiled: December 2, 2019Date of Patent: April 2, 2024Assignee: DANFOSS POWER SOLUTIONS, INC.Inventors: Jaromir Tvaruzek, Samuel Hall, Phil Evans, Dennis Greene

Publication number: 20210164501Abstract: Hydraulic axial piston unit having a rotational group for driving or being driven by a driving shaft, and a tiltable displacement element for adjusting the displacement volume of the rotational group. The rotational group includes a rotatable cylinder block in which working pistons are mounted reciprocally moveable in cylinder bores for conveying hydraulic fluid from a kidney-shaped inlet port to a kidney-shaped outlet port on a valve segment. At least two control ports are located on the valve segment each between the respective circumferential ends of the kidney-shaped inlet port and the outlet port. The control ports can be brought sequentially in fluid connection with the cylinder bores when the cylinder block is rotating. At least one hydraulic fluid injector is connected fluidly to one control port, for sequentially injecting pressurized hydraulic fluid via the control port into the passing cylinder bores. Via the other control port hydraulic fluid can be drained from passing cylinder bores.Type: ApplicationFiled: December 2, 2019Publication date: June 3, 2021Inventors: Jaromir Tvaruzek, Samuel Hall, Phil Evans, Dennis Greene

Patent number: 10249063Abstract: A method of reconstructing a 3-dimensional image in a proton transmission computerized tomography (CT) apparatus is disclosed. The method comprises the creation of a reconstruction matrix. The matrix is created by directing a plurality of particles to traverse the object; and for each particle, measuring the trajectory and energy of each particle before and after it has traversed the object; for each particle, calculating the water-equivalent path length within the object; and for each particle, calculating the positions at which it entered and exited the object; and adding the water-equivalent path length, entry and exit positions to the reconstruction matrix. This procedure is repeated from a plurality of angular positions surrounding an object to be imaged. Then, a spatially varying 2-dimensional filter function is applied to the reconstruction matrix. Subsequently, a correction factor is applied to the filtered reconstruction matrix to at least partially correct for the finite extent of the matrix.Type: GrantFiled: July 30, 2015Date of Patent: April 2, 2019Assignee: University of LincolnInventors: Nigel Allinson, Phil Evans, Gavin Poludniowski

Patent number: 10005117Abstract: An apparatus, system and method for seaming an end cap to an end of a target object using a fixed, rigid roller carriage that is configured to move along a direction that is orthogonal to a rotation axis of the end cap and the target object. The end cap seaming apparatus and system preferably comprise servo motors that move the roller carriage and rotate the end cap and the target object. The end cap seaming apparatus and system may be configured to learn the shape of the end cap and the target object by learning a shape of an end cap holding member on which the end cap is held. An automated method of seaming the end cap to the target object is executed based on the learned shape of the end cap holding member.Type: GrantFiled: October 20, 2015Date of Patent: June 26, 2018Assignee: ADMC HOLDING, LLCInventors: Phil Evans, Victor H.
