Abstract: A heat exchanger including: first and second heat-exchange modules comprising fluid-circulation systems, partition plates which fluidically disconnect adjacent fluid-circulation systems, at least one of the heat-exchange modules including: a frame plate of constant thickness, including a through-aperture, and an insert fully housed in the aperture and of a thickness equal to the thickness of the frame plate, and consisting of a single shaped plate or a plurality of shaped plates forming a stack and each consisting of at least one hollowed-out zone passing through it and a surrounding solid zone of constant thickness, the corresponding fluid-circulation system being formed in the hollowed-out zone of the single plate or of each plate of the stack and bounded by the surrounding solid zone or zones and by the adjacent partition plates.

Abstract: A heat exchanger includes first and second modules having first and second systems for circulating first and second fluids respectively, the first fluid comprising different first and second fluid components, partition plates in contact with the adjacent modules and each fluidically disconnecting the first and second circulation systems from one another. Each of the second modules includes a third circulation system, fluidically disconnected from the second circulation system, the first and third circulation systems being fluidically connected through the partition plate. The exchanger introduces a change in phase of the second component by exchanging heat between the first and second fluids and directing the first and second components out of the exchanger through the first and third circulation systems.

Abstract: A heat exchanger has first and second heat-exchange modules including first and second fluid-circulation systems, partition plates sandwiched between first and second heat-exchange modules and each fluidically disconnecting the first and second fluid-circulation systems from one another. At least one of the heat-exchange modules includes a stack of shaped plates superposed along a longitudinal axis, and each consisting of at least one hollowed-out zone passing through it and of a surrounding solid zone of constant thickness, the corresponding fluid-circulation system being defined by the hollowed-out zones of the stack and extending between the adjacent partition plates, at least part of the hollowed-out zone of one of the shaped plates being superposed with a solid zone of another shaped plate adjacent to it, and vice versa.

Abstract: An adjustable spinal stabilization system for maintaining preselected spacing and movement between adjacent vertebrae in a spinal column and for providing overall stability thereto. The system includes at least one interlaminar member positioned in the spaces intermediate a first vertebra and the vertebrae positioned immediately above or immediately below and adjacent to the first vertebra. The interlaminar member is operatively connected to an adjustable support structure and cooperates therewith to maintain the preselected spacing between adjacent vertebrae and to provide overall stability to the spinal column.

Abstract: A sacroiliac joint fusion procedure using surgical instruments specifically designed for access and treatment at a posterior inferior access region to the cartilaginous portion of the SI joint. The system allows for fewer devices implanted in the patient to reduce potential risks which are increased when having to place three or more implants. Due to the special design which resists the shear and nutational forces present at the SIJ, just a single implant can be used therefore reducing the amount of metal implanted into the patient while allowing for a great area for bone healing and bridging which provides a lasting relief to the otherwise excruciating low back, buttock and leg pain originating from the degenerative sacroiliac joint.

Abstract: A system for performing a fusion procedure on a sacroiliac joint defined between a sacrum and an ilium. The system may include a working cannula including a proximal end, a distal end, a tubular body extending between the proximal and distal ends, a cannula passageway defined within the tubular body and having a cannula axis extending there through, a pair of prongs coupled to the tubular body and extending distally there from, an anchor arm engagement structure coupled to the tubular body, and a pin guide coupled to the tubular body and defining a pin passageway having a guidance axis there through that is generally parallel with the cannula axis.

Abstract: A method of diagnosing and treating a sacroiliac joint of a patient involving delivering a first member into the ilium via a first posterior approach, delivering a second member into the sacrum via a second posterior approach, coupling the first and second members to a pliers, and manipulating the first member relative to the second member via the pliers to determine an ailment of the sacroiliac joint.

Abstract: The double-regulated turbine comprises a spherical hub, adapted to rotate around a first rotation axis, and blades, which are each able to be swivelled relative to the hub around a second rotation axis, transversal to the first rotation axis, by respective coupling flanges that are mounted fixedly on the spherical hub and that include each an attachment surface for a corresponding blade. The attachment surface of the coupling flanges includes a flat portion.

Abstract: A turbine unit for a hydraulic installation, and more in particular it deals with the hub of the turbine unit. The present invention proposes to provide means for adjusting a gap extent formed between the hub and the inner edge of the blade, this way dramatically increasing the performance of the turbine.

Abstract: The invention provides methods and composition developed to be used with imaging techniques and useful for diagnosis and monitoring the pain generator(s) of axial pain with or without radiculopathy and methods for screening therapeutic compounds potentially useful for treating axial pain with or without radiculopathy. Alternatively, degenerated discs can be monitored and treated before occurrence of a pathological pain condition. Pain markers and markers of degeneration include markers of neuronal, vascular, immune and matrix elements.
