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).

Abstract: The invention relates to a method for proving the existence of a polynucleotide sequence A in a sample containing a plurality of identical or different polynucleotide sequences X as individual strands and where the polynucleotide sequence A may be identical with one of the polynucleotide sequences X or may be contained as a sequence portion in one of the polynucleotide sequences X, through the inquiry of the state of linkage of the polynucleotide sequences X contained in the sample to a known test polynucleotide sequence B complementary to the polynucleotide sequence A, comprising the following steps: preparation of a test medium containing as individual strands test polynucleotide sequences B complementary to the polynucleotide sequence A which is to be proven, establishing contact of the sample with the test medium by placing the sample into or onto the test medium such that the individual strands of the polynucleotide sequences X contained in the sample may bind to the complementary test polynucleotide seq

Abstract: A heat shield having a thermally conductive body. 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: The microstrip line for high frequency applications has a metallic ground electrode, a metallic signal conductor and a dielectric arranged between ground electrode and signal conductor. The dielectric consists of a relaxed, more specifically pre-stretched, polymer film that is coated on one side with a self-adhesive layer.

Abstract: The present invention relates to an actuator for electromagnetic valve control in which the yokes of the electromagnets have a slotted design by means of the yokes consisting of a plurality of solid parts joined to one another.

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: An actuator for electromagnetically controlling a valve with a device comprising a magnetic field sensor and a magnetic field transmitter for determining the instantaneous position of a retaining plate, the magnetic field sensor and the magnetic field transmitter being surrounded by magnetic screening.

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).
