Abstract: A blade structure for use in a fluid flow rotary machine wherein the blade profile is thickened within the head region and a cover plate is connected to the head end within the thickened region by means of a substantially loop-shaped welded joint which is made by use of a high-energy beam such as an electron beam applied to the surface of the cover plate. The starting and end portions of the welding run can be overlapped, and the intensity of the welding beam is gradually increased from the starting point of the run to eliminate any swelling effect and is gradually reduced towards the end of the run to prevent crater formation.

Abstract: The invention relates to a device for sealing of the aperture in a weapon cupola for the barrel of the weapon and which permits elevation movements of the barrel. The device comprises an elongate bellows made of plastic material which is divided into two halves which are in contact with each other along the center line of the barrel aperture. The barrel extends out between and presses the two halves of the bellows apart. Because of the bellows-shaped elastic material, this pressing apart can easily take place, and the bellows resumes its shape and covers the barrel aperture both below and above the barrel. In order to cover the gap which arises just above and below the barrel a protective plate is adapted to the bellows and thus participates in the elevation movements of the barrel.

Abstract: A fuel control system for an electronically controlled fuel injected internal combustion engine, whereby fuel is injected into the cylinders for a fixed number of degrees with respect to the crankshaft rotation. A trigger pulse is fed into a tachometer circuit (32) giving a DC ramp output with respect to speed. A portion of this ramp signal is fed into a monostable circuit (31) whose output pulse duration is now speed dependent and remains constant in degrees of engine crankshaft as the speed of the crankshaft increases. By adjusting the slope of DC ramp output fed into the monostable circuit (31), the fuel "on" time may be set to any fixed number of engine crankshaft degrees desired for a particular engine.

Abstract: A lithographic sheet fed press having means for clearing a jamming condition in which a plurality of sheets become wedged between the blanket and impression cylinders. The blanket cylinder is journaled in eccentric bushings having respective operating arms. Toggle linkages are respectively interposed between each arm and the associated frame plate and settable in a slightly overcenter operating condition for maintaining normal printing pressure between the blanket cylinder and the impression cylinder. A toggle-breaking power actuator is laterally coupled to the toggle linkages for breaking the same to the opposite side of dead center. A back-off power actuator is coupled to the bushings for imparting substantial rotation to the bushings accompanied by relief of pressure and full collapse of the toggle linkages with scissoring action. The actuators are energized in sequence to secure (a) release of the toggle linkages and (b) backing off of the blanket cylinder from the impression cylinder. The toggle linkages are re-set to their overcenter operating condition following removal of the wedged sheets. The toggle linkages are mirror images of one another and are preferably interconnected by cross shafting to keep the movements at each end of the blanket cylinder in step with one another.

Abstract: Leakage cancelling apparatus suitable for use in electrosurgery apparatus to prevent electrical burns is disclosed. The apparatus comprises a transformer which is connected in the electrical circuit between the electrosurgical source and the patient. The transformer has a primary winding connected in series with the active surgical electrode and a secondary winding connected in series with the return path to the electrosurgical generator. The connections to the windings are polarized so that during normal operation the magnetic fields in the transformer core generated by current flow are almost completely cancelled. Consequently, the transformer windings present very small impedances in series with the electrosurgical circuit. If a break occurs in the return lead of the electrosurgical circuit and the patient becomes ungrounded, a condition which would normally result in a high risk of a burn, the currents in the primary and secondary windings of the transformer become unequal, the magnetic fields in the transformer core do not cancel and the transformer windings present a significant impedance to the flow of electrosurgical current which reduces the occurence of electrosurgical burns. In addition, the uncanceled inductance presented by the transformer windings during a break situation may be chosen to resonate with the leakage capacitance of the electrosurgical circuit, further reducing the current flow and preventing burns.

Abstract: @ In the processing of a material web provided with crease lines a reel is used frequently for registry. The reel comprises one or more axial rules, the distance between these being adapted to the distance between transverse crease lines of the material web. To ensure a correct engagement with the crease lines, the rules are relatively sharp which may cause damage to the material web. This is prevented in accordance with the invention in that supporting elements are provided at the end of the rules so that any material extending beyond the ends is not folded or broken. The reel moreover comprises adjustment facilities for adapting itto varying distances between the transverse crease lines of the material web.
