Abstract: A pressure sensor is configured to monitor a first resistance value of a first resistor and a second resistance value of a second resistor. The first resistor and the second resistor are configured to be sensing elements of a sensing component of a pressure sensor. The pressure sensor is configured to determine, based on a difference between the first resistance value and the second resistance value satisfying a threshold, that a measurement from the sensing component is unreliable. The pressure sensor is configured to perform, based on determining that the measurement from the sensing component is unreliable, an action associated with the pressure sensor.

Abstract: A calibration device for a network analyzer with several ports provides a calibration circuit, which is connected in each case via a terminal port respectively to one of the several ports of the network analyzer. A first transistor and a second transistor are connected in series to each terminal port. In this context, both transistors are connected by their common connection to the terminal port. The first transistor and/or the second transistor is operated as an adjustable load.

Abstract: A method and apparatus involving releasing the rotor (1) and turning it to and fixing it at top dead center, attaching an extractor head to an exposed end of the hammer axle. A cross-piece (2.1) is applied and a releasable element of a slide (2.4) of a hammer axle puller is pulled, making a releasable connection between cross-piece and rotor attachment elements. The slide is moved to a position in which the puller head is connected to the slide in a shape-locking manner, securing the hammer position, returning the carriage whilst extracting the hammer axle (1.5) to release the hammer. The connection between the head and slide is released, moving the slide until the head and slide re-engage and returning the slide again to extract the hammer axle until the entire hammer and/or protective cap (1.4) and axle if appropriate are extracted. An Independent claim is also included for an arrangement for implementing the method.

Abstract: The invention relates to a rotor (1) for a reducing machine. According to the invention, the protective caps (6.1) covering the outer plates (3.1) of the rotor (1) are decoupled from the forces of the hammer axles (5) and from the forces exerted directly on the outer protective caps (6.1) by the hammers. The outer protective caps (6.1) which are exposed to the lateral forces of the hammers (4) encompass the outer edge of each of the plates (3.1) with a web (6.2) and encompass each of the inner steps (3.2) of the plate (3.1) with a projection (6.5) in the shape of a ring segment. At the same time, these outer protective caps (3.1) are mounted on the plate (3.1) with a positive fit by means of a connecting element (9) such as a hexagon socket screw. The outer protective caps (3.1) which are adjacent to the inner protective caps (6) are fixed to the outer plate (3.1) with a non-positive fit, also by means of connecting elements (9) such as hexagon socket screws (3.1).

Abstract: A device for synthesizing oligonucleotides includes a back plate (17) having a support material suitable for synthesis. Reaction cells (2, 3, 4, 5) are assigned to the support material, which reaction cells are open on the side facing the support material (19) and can be sealed against the support material (19). The back plate (17) can be slid vertically in the direction of gravity. The reaction cells (2, 3, 4, 5) can be repeatedly placed in this manner on the support material (19) along a sweep track running in the vertical plane.
