Abstract:
A fuse (10) is proposed for interrupting a voltage and/or current-carrying conductor (12) in case of a thermal fault, having a conductor bar (14) ensuring an electrically conductive connection of the voltage and/or current-carrying conductor during correct operation, said fuse (10) being characterized in that the conductor bar (14) melts upon an increase in temperature above the melting point, and the electrically conductive connection of the voltage and/or current-carrying conductor is interrupted due to inherent surface tension. Also proposed is a method for producing the fuse (10) according to the invention.

Abstract:
The invention relates to a component for installation in force or pressure sensors, in particular in a glow plug. The component comprises a disc-type or punched-disc type measuring element consisting of a piezoelectric material, punched-disc type or disc-type electrodes that lie on either side of the measuring element. The electrodes have contact points for contacting conductors. The component comprises in addition a respective transmission body or several transmission bodies that are located outside the electrodes, on either side of the latter. The measuring element, electrodes and transmission bodies are held together mechanically by an external, electrically insulating film.
Abstract:
The invention relates to a pressure sensor (1), comprising a housing (2), a housing element (3) which may be exposed to a pressure chamber (10), mounted on the housing (2) by means of a metallic membrane (5) and a measuring cell (4) which can indirectly measure a pressure acting on the housing element (3) and transmitted to the measuring cell (4) as a force resulting therefrom. According to the invention, said pressure sensor (1) comprises a housing element (3) embodied as a pin and projects out of the housing (2). The advantage of such an arrangement is only a small drilling to a pressure chamber (10) need be provided, in order to carry out a pressure measurement. The pin (3) need only be so long that the front end thereof, in the assembled state, approximately reaches the wall (11) of the pressure chamber (10).
Abstract:
A bearing tool includes a first ring, whose inner diameter is larger than the outer diameter of the inner ring of the bearing and whose outer diameter is larger than the inner diameter of the outer ring of the bearing; a second ring, which is coaxial with the first ring, has an outer diameter smaller than the inner diameter of the first ring and the inner diameter of the outer ring of the bearing, and has an inner diameter smaller than the outer diameter of the inner ring of the bearing; and a force-exerting part, which provides an action force to change the axial relative position between the coaxial first and second rings. The bearing is coaxially held between the first and second rings, so that one end in the axis of the first ring urges against the opposite surface of the outer ring of the bearing and one end in the axis of the second ring urges against the opposite surface of the inner ring of the bearing. The action of the force-exerting part is mediated by the first and second rings to change the axial relative position between the inner and outer rings of the bearing.
Abstract:
A scale having an electronic weighing system to generate a weight-dependent signal and a digital signal processing unit (18). The digital signal processing unit (18) has a circuit or program parts which measure the time elapsed since connection of the voltage to the scale. To dramatically reduce the time required for the scale to reach its full accuracy after connection of the voltage supply, the digital signal processing unit (18) has computation modules (34, 35) that correct the weight-dependent signal generated by the weighing system by a correction value that depends on the time elapsed. The magnitude of this correction value, starting from an initial correction value, converges with increasing time elapsed to a constant end value that differs from the initial correction value.

The invention relates to an aqueous pigment preparation containing an organic and/or inorganic pigment dispersed in an acrylate resin solution and a dispersion agent. The preparation is characterized in that the acrylate resin is a copolymer consisting essentially of between 50 and 80 mol % of monoalkenyl aromatic compounds and between 20 and 50 mol % of acrylates, and has an average molar mass Mv of between 1,000 and 50,000 g/mol, and in that the dispersion agent is a compound of formula (I): R—O—(CH2-CH2—O)m—CH2—COOM, wherein R is a C10-C20 alkyl radical or a C10-C20 alkenyl radical, m is a number between 1 and 15, and M is a monovalent cation.
Abstract:
An organic material can be used in a modified strain gauge for IR transduction, resulting in an organic IR sensor. Infrared radiation incident on the organic material modulates a displacement of the material in order to detect the presence and intensity of IR radiation. This innovative design doesn't require cooling, and is sensitive to 9 and 3 μm—wavelengths that are emitted by mammals and forest fires, respectively. In addition, a photomechanical polymer can be used in a transistor based on a thin-film transistor (TFT), also resulting in an IR sensor. Through careful synthesis of the polymers, the photomechanical response of the transistor can be tailored to certain IR bands for detection purposes.
Abstract:
A method, a computer program product, and a system for generating and applying patches to a computer program concurrently with its execution. It provides full support for function pointers, transparent to the programmer and nearly transparent to the concurrent loader. A reference to a function pointer is translated into a sequence of processor instructions called function descriptor instead of translating it into an address. The purpose of the function descriptor is to jump to the memory location of the sequence of instructions generated by the compiler for the procedure referenced by the function pointer. The function descriptor is masked as a static data variable and therefore preserved during the application of a concurrent patch. The address for the jump to the procedure is updated by the regular relocation process during the application of a concurrent patch.
Abstract:
A weighing system, using the principle of electromagnetic force compensation, which includes a permanent magnet system (14) having an air gap, a shielding cover (12), a coil (13) located inside the air gap, a transmission lever (7) to whose longer lever arm the coil is attached, and upon whose shorter lever arm the weight transferred by the load receiver acts, a position sensor (20, 21, 22) which detects the position of the transmission lever and which is situated in the vicinity of the coil, and a control amplifier (16) for controlling the current passing through the coil. Further, at least one vertical support (25) is connected to the transmission lever in the vicinity of the coil and the position sensor and projects through an opening (27) in the shielding cover. A counterweight (26) is placed on this/these support(s) closely above the shielding cover.
