Abstract: A load cell (1) has a deformable body with upper and lower contact surfaces (3, 4), through which a force is introduced. Support points (5) of the contact surfaces define a line of action (6) of the force. At least one column-shaped portion (7) of the deformable body has a central longitudinal axis (8) and a circumferential surface whose generating line runs parallel to the central longitudinal axis (8). A first determining means (9) installed on the column-shaped portion converts a mechanical deformation into an electronic signal, and a second determining means (10) installed on the column-shaped portion converts a deviation of the central longitudinal axis (8) from the line of action (6) into a representative signal. Each determining means has at least one strain gauge.

Abstract: A device and method for effectuating the temperature compensation testing of digital load cells. The device uses conductive heat transfer to establish and maintain the temperature of the load cell(s) during testing. The device may include a vessel into which one or more load cells to be tested are placed. Temperature control of the load cells may be accomplished by circulating a temperature controlled fluid through the vessel. The vessel containing the one or more load cells may then be placed in a load application device that applies a load(s) to the one or more load cells during testing. Readings from the one or more load cells are used to establish a temperature compensation factor for each load cell tested. In other embodiments, temperature control of the load cells may be accomplished by placing the load cells in contact with a solid heat transfer element(s).

Abstract: An interior space of the at least one housing of a force-measuring device is filled with a gas composition that is distinguishable in at least one parameter from the ambient atmosphere. A sensor that is arranged in the interior space, or on the housing, measures this distinguishable parameter. A processing unit of the force-measuring device compares signals obtained from the sensor to monitor and determine the condition of the force-measuring device.

Abstract: An exemplary mounting arrangement serves for the mounting of a force transducer that has a sensor-equipped core part connecting a support part to a force-application part. The support part can be bolted to a fastening part by mounting screws, and the force-application part can be bolted to a weighing pan carrier by means of mounting screws. The support part and the force-application part of the force transducer can each have a triplet of threaded holes serving to receive the mounting screws. Each triplet forms an isosceles triangle whose apex points towards the deformable body. The symmetry axes of the triangles lie in a plane that is parallel to the displacement travel of the force transducer. The mounting arrangement can be further configured to provide an effective overload protection in a low-profile design and to provide a thermally uncoupled fixation.

Abstract: An extended component made of fibre-reinforced thermoplastic materials, in particular a screw (1) that contains a corresponding proportion of fibres. Carbon fibres shaped as endles fibres extend in an at least approximately parallel direction to the centre line of the screw (1) in the area of the head (2) of the adjacent thread turns of the shaft (5). At the surface of the remaining part of the threaded portion, the fibre follow the contour of the thread in the axial direction of the part. The fibres in the core of this section next to the end of the screw are distrubuted in an increasingly random manner towards the free end of the screw.

Abstract: Method for random-access communication in communication networks (1) with time-slotted transmission channels which are being accessed by a plurality of terminal devices (2), whereby the terminal devices (2) are provided with binary feedback (S/{overscore (S)}) by a common receiver (3), a positive feedback (S) indicating that a particular slot contained a successfully transmitted packet or a negative feedback ({overscore (S)}) indicating that the particular slot did not contain a successfully transmitted packet, and whereby dummy packets are transmitted by an auxiliary user (4) following the first negative feedback ({overscore (S)}) after a prior collision has been resolved to determine whether said negative ({overscore (S)}) feedback was due to a collision of packets in the respective slot or whether it was due to this slot having been empty.
