Filed: 1988-04-11
Abstract: A first desired acceleration value (A1) is continuously determined by a non-linear course regulator, and, parallel thereto, a second acceleration value (A2) is continuously determined by a non-linear speed regulator. By means of a simple selection criterion comprising only these two alternative acceleration values, the second alternative desired acceleration value is brought into action by a selection circuit (18) for the running-up, the first alternative desired acceleration value is brought into action for initiating the target braking, and the second alternative desired acceleration value is again brought into action for running into the target position. Changes in the travel target and the speed of the position drive (PA), in particular the realization of creep speeds, are possible to virtually any extent during travel.

Abstract: A pressure relief panel assembly (20) for rupture discs, explosion vents and the like has a plurality of frangible panel portions (140, 44, 50) which burst at different pressures to present a pressure relieving aperture having a cross-sectional area which varies in accordance with the number of panel portions (40, 44, 50) which have ruptured. In one embodiment of the invention, the assembly comprises two frangible panels (26, 30) positioned in face-to-face relationship in covering disposition to a vent opening, and the innermost panel has an orifice which functions as a pressure relieving aperture once the outermost panel ruptures; subsequently, further build up of pressure causes the innermost panel to burst and present a pressure relieving aperture larger than the orifice so that the structure to be protected is fully vented. In certain forms of the invention, a dis­continuous pattern of perforated lines of weakness in the innermost panel serve as pressure relieving apertures once the outermost panel ruptures. In another embodiment, the assembly comprises a single panel (125) having one set of weakness lines (142) defining a first frangible panel portion (140) and a second set of weakness lines (142) surrounding the first set and de­fining a second frangible panel portion (144).

A connecting rail (1) is used for the connection and can be combined in a positively locking manner with the top walls of the electrical cabinets (2, 3), such that it is moved along the top joint of the electrical cabinets (2, 3). For this combination, the shafts of mushroom-headed elements (4) are in each case pushed through slots (5) and the heads of the mushroom-headed elements (4) engage behind said slots. The mushroom-headed elements (4) are arranged in two parallel rows in the connecting rail (1), while the slots (5) are located in the top walls of the electrical cabinets (2, 3), or vice versa. The arrangement is designed such that the rows of mushroom-headed elements (4) and the slots (5) flank the top joint of the electrical cabinets (2, 3) when the connecting rail (1) is in the intended position. The connecting rail (1) is secured in its intended position by a single screw connection, which consists of a screw engaging through the connecting rail (1) and a nut which is anchored in one of the top walls of the electrical cabinets (2, 3). <IMAGE>

Abstract: A stator for eccentric worm pumps consists of a fixed stator casing (10) and an elastic inner part (16). The stator casing (10) has an internal thread (12) in the direction of rotation of the pump rotor and the inner part (16) has a corresponding external thread (14). By screwing the inner part (16) into the stator casing (10), an exceptionally robust and durable and economically produced mechanical connection is obtained between these parts, which does not come loose during operation of the pump but is further strengthened. The internal thread (12) can taper slightly conically in the delivery direction (20) of the pump while, in the unstressed state, i.e. when not screwed in, the external thread (14) of the inner part (16) is cylindrical. When the inner part (16) is screwed into the stator casing (10), the inner part (16) is therefore subjected to increasing radial prestress in the delivery direction (20), the volumetric capacity thereby being increased.

Abstract: The known processes for the preparation of fine boehmite crystals for use as pigments and/or fillers are not suitable since their products are excessively coarse and the yields of boehmite are relatively low compared with the amount of seeds used. The novel process gives a novel, fine, platelike, crystalline boehmite having a particle size of between 0.2 and 0.8  mu m, which makes it suitable for use as a pigment and/or filler in paints, papers, writing fluids, and the like. A lye from the Bayer process or another Na2O- and Al2O3-containing lye is kept in contact with an oxygen-containing gas at elevated temperature and pressure until a molar ratio of less than or equal to ... . The oxidised lye is then cooled under the hydrodynamic conditions of vigorous stirring, and nucleation and crystallisation of boehmite is thus initiated. The boehmite obtained is platelike and preferably in a fine grain size, greater than 90% in the range from 0.2 to 0.8  mu m. Use as a pigment/filler in paper, paints and writing fluids.

IPC: G01R31/26
Filed: 1988-05-11
Abstract: An in-circuit test device and method for testing transistors (24) which are connected to various components (10) on a printed circuit board (12). The present invention uses a fully automated system which provides a constant emitter current (I E ) to bias the transistor (24) to a predetermined level and prevents the transistor (24) from going into saturation due to variations in the gain of different transistors. The collector lead (26) and base lead are maintained at approximately ground potential so that the collector emitter voltage drop is maintained above the saturation voltage for transistors since the base emitter junction is biased by a constant emitter current placed in the emitter lead. Transistor gain is determined from the difference in two separate d.c. emitter currents which eliminates the effects of parallel impedance paths resulting from other components connected to the transistor on the printed circuit board. An operational amplifier (38) having a feedback resistance (42) is used so that the output voltage (V O ) is directly proportional to the current flowing through the base of the transistor (24).
