Abstract: The invention relates to a method for measuring the electrode force on welding tongs. The welding tongs have a first electrode arm with a first electrode and a second electrode arm with a second electrode, said second electrode arm lying opposite the first electrode arm. At least one workpiece is clamped between the electrodes during the welding process. The aim of the invention is to provide a method for measuring the electrode force, said method providing an improved signal quality. The method has the following steps: a) measuring a first force acting on the first electrode, b) measuring a second force acting on the second electrode, and c) adding the measured first force and the measured second force, wherein an electrode force signal transmitted from the welding point to the electrodes is amplified, and an interference force signal introduced into the at least one workpiece from the outside and transmitted to the electrodes is eliminated.

Abstract: A system for improving outcome following cerebral ischemia is provided. The system includes a source of nitric oxide and an elongate tubular member for insertion into a nose including at least one orifice thereon. The elongate tubular member is coupled to the source of nitric oxide and configured for delivering the nitric oxide into a nasal cavity through the at least one orifice for absorption into a cerebral vasculature through a nasal vasculature. A device for controlling flow of the gas, a concentration of the nitric oxide in the gas, or both, is also provided.

Abstract: A method of modulating a physiological parameter of a patient is provided. The method includes disabling one or more pre-aortic ganglion cells within a pre-aortic ganglion and improving the physiological parameter. The method further includes destroying a pre-aortic ganglion cell to prevent regeneration.

Abstract: A method of modulating a physiological parameter of a patient by percutaneously or transcutaneously disabling one or more pre-aortic ganglion cells within a pre-aortic ganglion via the anterior abdominal wall and improving the physiological parameter is provided. The pre-aortic ganglion cells may be disabled by applying radiofrequency, high intensity or low intensity focused ultrasound.

Abstract: A non-invasive method of treating cerebral ischemia, involving the use of non-inhaled, intra-nasally delivered carbon dioxide (CO2), alone or in combination with other gases to augment cerebral perfusion and improve outcome following a stroke is provided. A vasodilator gas is delivered intranasally, alone or in combination with a second gas, for prolonged periods of time without systemic absorption. The second gas may be selected from NO, hydrogen, xenon, anesthetic gases, oxygen, nitrogen, nitrous oxide, carbon monoxide, or air. The treatment selectively increases cerebral perfusion and provides neuroprotection in the treatment of cerebral ischemia.

Abstract: A method of modulating a physiological parameter of a patient is provided. The method includes disabling one or more pre-aortic ganglion cells within a pre-aortic ganglion trans-venously and improving the physiological parameter. The method further includes destroying a pre-aortic ganglion cell trans-venously to prevent regeneration.

Abstract: Apparatus for resistance welding with different welding currents has a welding transformer having a primary and a secondary side. Two welding electrodes are connected at the secondary side to the welding transformer and are each arranged on a respective control arm, one of the arms being movable by an actuating drive. A control and regulating arrangement is connected on the primary side between the welding transformer and a connection to a three-phase network. The control and regulating arrangement has a rectifier circuit connected to all three phases of the network and a controllable welding inverter for converting the rectified voltage into voltage pulses of alternating polarity at a predetermined frequency. At least one electronic component of the rectifier circuit and/or the welding inverter is connected to the drive for moving one of the control arms, for controlling and/or powering the drive.
