Abstract: An electronic assembly includes an electronic circuit on a circuit board. The circuit includes a conductor path on the circuit board, and at least one SMD component, electronic component and/or electromechanical component that is mounted on the circuit board and connected to the conductor path. A circuit connection between any two of the conductor paths and/or the components is established via a soldered joint and a spring-loaded contact bridge. In the event of excessive power dissipation, the soldered joint melts or weakens and the contact bridge opens due to the spring force.

Abstract: The invention relates to a torque-splitting differential (1) for a motor vehicle, comprising two coaxially aligned lateral differential gears (10, 10?) that are spaced apart in the axial direction, each lateral differential gear (10, 10?) being mounted to be rotatable about a common axis of rotation D. The differential has at least two compensating gears (20), each of which meshes with both lateral differential gears (10, 10?). A compensating gear support (30), on which the compensating gears (20) are rotatably mounted and which is arranged between the lateral differential gears (10, 10?), is mounted to be rotatable about the axis of rotation D. The lateral differential gears (10, 10?) are designed as crown gears, of which the teeth have different diameters. Furthermore, the compensating gears (20) are spur-cut gears while the compensating gear support (30) rotatably rests against the lateral differential gears (10, 10?).

For that purpose, according to the invention, a number of connections between conductor strips (6), components and/or elements is produced via respectively one spring-loaded contact bridge (12, 12?, 12?, 12??).

Abstract: A method according to the invention makes it possible to make a check of the correct installation and operation of piston cooling nozzles (10) in a cold text prior to the final assembly of the engine by applying compressed air to each piston cooling nozzle (10) and directing the jet of compressed air emitted by the piston cooling nozzle (10) to be checked toward a surface pressure sensor (24). This makes it possible to record the position of the compressed air jet generated by the piston cooling nozzle (10) and preferably also the geometry of the jet. It is thereupon possible to draw conclusions concerning the proper operation and installation of the respectively checked piston cooling nozzle (10).

The material of the body is composed of a fibre composite material, preferably carbon fibre, glass fibre, glass-fibre-reinforced plastic and/or aramide, and layers of a heat-conductive metal. Cooling tubes may be applied to an outer surface of the body, incorporated into an outer fibre layer of the body, and/or formed directly within the outer fibre layer.

Abstract: An article of footwear including an upper and a sole, which has an outsole for directly contacting a ground surface, and at least one element compression molded with the outsole. The at least one element is formed from a first material including at least 45% ethylene vinyl acetate, approximately 30% polyene elastomer, and approximately 20% synthetic rubber. A second material of the outsole is compatible for compression molding with the at least one element, and is less hard and less dense than the at least one element.

Abstract: A method of operating an actuator for electromagnetically controlling a valve in an internal combustion engine involves supplying a heating current to the operating coils of the actuator before starting the internal combustion engine from a cold start condition. Thereby, the operating coils, the components surrounding them, and the lubricant are heated to ensure proper viscosity of the lubricant and thus proper operation of the actuator.

Abstract: On a known electromagnetic actuator for valve control of an internal combustion engine an armature (1) is moved by magnetic force between the pole faces (21, 31) of an opening magnet (2) and a closing magnet (3) to activate an intake/exhaust valve (5). Owing to the work that has to be done when the intake/exhaust valve (5) is opened in order to counteract the high internal gas pressure in the combustion chamber the opening operation takes longer than the closing operation. The disclosed actuator permits faster opening of the intake/exhaust valve (5), in that the magnetic force exerted by the opening magnet (2) is increased for large stroke lengths (d.sub.o) in comparison with the magnetic force exerted by the closing magnet (3) on the armature (1) in conjunction with the same stroke length (d.sub.s) by the provision of a two-section connecting sleeve (7) enclosing the space between the pole faces (21, 31).
