摘要： It is disclosed for a balance with a scale on top based on the principle of the electromagnetic compensation of force with a system carrier fixed to the housing, with a load receiver, with two guide rods which connect the load receiver to the system carrier in a vertically movable direction as parallel guide, whereby the stem carrier, the two guide rods and the load receiver are designed as a one-piece casting, with a translation lever and with a coupling element between load receiver and translation lever, whereby the force from the load receiver corresponding to the mass of the weighed material is transferred via the coupling element to the shorter lever arm of the translation lever and the coil of the electromagnetic compensation of force is fastened to the longer lever arm of the translation lever that the system carrier comprise lateral projections which extend into the area between the guide rod arms. This achieves a distinct reinforcement of the system carrier without having to increase the outer dimensions of the system. The stability of the entire system can be further increased by means of further reinforcement measures in the lad receiver and in the guide rod arms.

摘要： The invention indicates a balance with counting scale in which the resolution of the balance with counting scale can be increased in the determination of the reference weight of light pieces without an additional switching key operated from the outside. To this end, a comparator (14) is present in the built-in electronic circuitry which is actuated when the transfer key (8) is pressed and which frees the transfer of the weight into the memory (16) and the determination of the average individual weight when a set threshold is exceeded, while, when this threshold is dropped below, it does not free the transfer of the weight into the memory and increases the resolution of the balance by a given factor.

The flat filter element (1) is formed by a flat filter band pleated into a plurality of close folds and adapted to the inside dimension of a hollow chamber (30) in length, width and depth, whereby it essentially fills up this inside dimension, whereby the open folds and the web backs of one side of the pleating face the sediment chamber (41) and the open folds and the web backs of the other side face the filtrate chamber (47), and the pleating, formed to a flat cuboid (plate), of the filter band blank constructed with at least one layer is surrounded in a frame-like manner by a plastic seal (6) and the latter is provided with a formed sealing flange (7) with which the filter cassette can be clamped in a leakproof manner between the housing parts. The pleating is covered on both sides by a support grid (10, 11) whose edges are anchored in order to brace the filter cassette in the material of the seal (6) and/or of the sealing flange (7).

摘要： In an electronic balance for application in potentially explosive areas, the weighing system, the electronic evaluation unit and the digital display unit have an intrinsically safe design with regard to the possibility of explosions. All lead connections are supplied with low voltages and the power unit when present is located outside the electronic balance and connected to the electronic balance via an explosion-safe lead and plug connections with an intrinsically safe design with regard to an explosion. In an alternative the power unit can be encapsulated in a pressure-proof manner, powder-filled, force-ventilated or located outside the potentially combustible gaseous explosive area. It is also contemplated that a battery which is intrinsically safe with regard to explosions can also be used in the housing of the electronic balance instead of a separate power unit.

摘要： In an analytical balance with a pan and a four-bar mechanism which keeps the balance pan parallel horizontally during its vertical travel, the one vertical side of which is held fast to the housing, the other vertical side of which, in the form of a coupling piece, carries an extension which receives the pan, and both horizontal sides of which are connected in an articulated manner by an upper and a lower rod to the vertical sides, whereby the four-bar mechanism is loaded by the restoring force of a load converter, the extension (16) which receives the pan (17) is L-shaped, the horizontal L-shank (pan arm) (16") carries the pan (17) rigidly connected to its free end and the vertical L-shank (bearing arm) (16') is mounted on the bar (18'") of a U-shaped arm bearing (18) which projects above and below over the vertically movable end (9) of the four-bar mechanism (5, 6, 7, 8, 9) with its two horizontal U-shanks (18, 18") in the rod planes and is rigidly fastened to it in two vertically superposed bearings (118'). Such a construction avoids the introduction of damaging torques from the extension (16) and the balance pan (17) into the sensitive parallel guide (5, 6, 7, 8, 9).

摘要： There is disclosed an axially folded tubular filter element for the filtration of fluids. The ends of the radially extending folds are in abutment at the internal folds with a support core and in abutment at the externally facing folds internally with an outer support grid. The support has a plurality of perforations. The ends of the tubular filter element are enclosed by a cap which encloses the ends of the tubular filter element in a sealing manner. The outside of the support core which supports the internally facing fold edges has a series of outwardly extending corrugated sections with rounded corrugated outwardly extending ridges, and the said perforations are located in the valleys of the corrugations. The corrugated structure extends in a longitudinal direction, is relatively flat and runs in a circumferential direction. A drainage pathway is also supplied along the outer surface of the support core.

摘要： In conventional fluorescent signaling devices the filament is fed with 50 Hz alternating current and the multiplex frequency of the signal ranges similarly in the area of 50 Hz, so that brightness variations occur with the difference in frequencies. A simple means for avoiding disturbing effect is the circuit of the present invention which divides the heating alternating current voltage into several stages and connects the negative terminal of the supply voltage of the fluorescent signaling device to one of the intermediate stages of the heating alternating current voltage depending on the signaling point that at the instant concerned happens to be lighted.
