Abstract: Track wheels, especially railroad wheels, are trued in a material saving manner by first displacing material from zones of lesser wear to zones of higher wear on the wheel tread and/or on the wheel flange including the flank area of the flange, especially that part of the flank merging the flange into the tread zone. The location of the new or restored tread is then determined and a material removing operation such as milling or turning is performed. The material displacing may be performed by a rolling or forging operation prior to the milling or turning operation.

Abstract: In the manufacture of an electrical strain gauge the strain-responsive circuit element is formed from a thin film deposit on a surface of a metal substrate on which an insulating film has already been deposited. Connections are made directly to the circuit element by the ends of conductor leads that are bonded into insulating plugs in apertures in the substrate. The plugs and the insulating film are glasses to which the substrate and the circuit element are bonded. A further glass layer encapsulates the circuit element. As a result a very robust form of gauge is provided that can be used in high temperatures and in chemically active environments.

Further exposed contacts electrically engage another electrical component and the housing member and the further exposed contacts maintain the other electrical component in the housing member. An electrical switch is part of the lead frame.

Abstract: A blade fuse includes parallel blades (12 and 14) secured in a body (16). A fusible link (42) welded to the blades is located in a cavity (20) of the body that is covered by a window (61). The blade fuses are assembled by blanking the fusible element from a ribbon (90) and translating it into a fuse subassembly (64). Tabs (50 and 52) secure the fusible element in the subassembly (64) until it is spot welded to blades 12 and 14. The window (61) is then blanked and translated to cover cavity (20) and secured by ultrasonic welding. A connector strip (76) is then blanked from between blades (12 and 14) to provide the blade fuse.

Abstract: A relay is sealed with a sealing compound when the relay housing is in a closed state, thus causing an air cushion to be formed in the inside, with an afterflow of sealing compound into the interior being prevented. Following gelling or curing of the sealing compound, a vent hole is pierced into the relay housing which, if required, may be closed following degassing of the interior space of the relay.

Abstract: The inventive method produces round parts consisting of profiled metal sections from a straight, profiled extruded section forming a wheel-like shape having butt ends joined together by welding. Bending the straight section into a round part is accomplished by first adjustably prestressing the straight section and then subjecting the prestressed section to a rolling bending operation. For this purpose, the section to be bent is wound either from one side or from both sides around the outside diameter of coordinated rolling dies the rotating rolling dies being able to additionally perform a translatory motion in the direction of the longitudinal axis of the section. The resulting wheel rim has the rim pan integrally joined to the rim ring.

Abstract: A method for machining a clutch gear for the transmission of an automobile which comprises forming a generally round annular bar made of malleable material in a cold forging or hot forging, urging the generally round annular bar against a die to form a final predetermined dimensional cross section and a chamfer projection simultaneously, fine blanking the chamfer projection into a tooth form and pushing the tooth form into a die from an end surface opposite the chamfer projection to form an inverted taper on the tooth form which prevents disengagement of the clutch.

Abstract: An insulating stay comprises: a central core (1) having high electrical resistance and high tensile strength; a sheath (2) of high electrical resistivity and comprising fins (3) to offer a maximum resistance path to possible surface current losses; and end fittings (4). The central core is made of resin reinforced with long, continuous fibers, and advantageously of epoxy resin reinforced with glass fibers. The sheath (2) is made of a natural or synthetic polymer, and advantageously of EPDM elastomer. The stay is manufactured by coating the central core (1) with a high viscosity glue (8) having high longitudinal resistivity, then wrapping said glue-covered core in a hollow tube (5) of raw elastomer and placing the assembly in a mold (5) where said fins (3) are formed in the sheath (2) and where the raw elastomer (5) is polymerized by vulcanization or reticulation. The stay is intended for bracing electrical installations that need to be insolated and placed at some distance from the ground.
