  • Patent number: 8009002
    Abstract: The invention relates to a universally applicable detachable magnet holder with a fixed magnet and an opposite-lying magnet which can rotate about a point of rotation and which is provided with magnet pole surfaces, wherein each magnet pole surface comprises at least two poles which, when closed, attract each other and which, when open, repel each other once the rotatable magnet has been rotated by means of an actuation device. According to the invention, a distance element (7), made of a non-ferromagnetic material, is fixed to one of the magnet pole surfaces, whereby the bearing surface on the opposite magnet pole surface is a maximum ? of the surface and a centering engaging device (10a, 10b; 11) is arranged in the vicinity of the magnet poles in order to receive magnetic sheer forces.

  • Patent number: 8004129
    Abstract: The aim is to avoid damaging lubricating-film discharges occurring via bearings (WL) in electrical machines. For this reason, provision is made for a current to be forced to flow through the bearing (WL) specifically, with the aid of a current source (IQ). The current then flows from one of the two bearing components via the lubricating film to the other bearing component. Alternating currents are particularly suitable since the lubricating film is conductive, so that the capacitance defined by the lubricating film cannot be charged, or can be charged only slightly.

  • Patent number: 7997431
    Abstract: An assembly has a mechanically movable element (1), by the movement of which an oscillatory system (2) can be excited to perform an oscillation which has a resonant frequency (f) and a corresponding oscillatory period (T). First of all, a control device (4) moves the mechanically movable element (1) at a first speed (v1). If the control device (4) is stipulated a second speed (v2) by an operator (7), the control device (4) determines a jolt profile, by means of which the speed (v) of the mechanically movable element (1) is changed to the second speed (v2), and moves the mechanically movable element (1) according to the determined jolt profile. Said control device (4) determines the jolt profile in such a way that an oscillation of the oscillatory system (2) which is excited at the beginning of the speed change is calmed at the end of the speed change.

  • Patent number: 7988942
    Abstract: A method for recovering diluted waste sulfuric acid by extractive rectification with concentrated sulfuric acid which is re-concentrated for reutilization. Waste sulfuric acid from the nitration process is fed into a first column, optionally together with another waste sulfuric acid in a DNT washing acid, and divided into an overhead product containing nitric acid and nitro-organic compounds and a prepurified sulfuric acid in the bottom product. The prepurified sulfuric acid withdrawn from the bottom of the first column is fed to the top of a second column, into the bottom zone of which another waste sulfuric acid is fed in the form of a diluted sulfuric acid recovered from the nitric acid concentration system so the prepurified sulfuric acid from the first column is further purified in the second column and is preconcentrated along with the diluted sulfuric acid recovered from the extractive rectification of nitric acid.

  • Patent number: 7980108
    Abstract: A bending device for a tubular member includes a bending tool which is rotatable about an axis. The bending tool includes a circumferential recess and is split transversely to the axis to form a first tool member and a second tool member. Extending tangentially to the recess and partly embracing the tubular member is a plate-shaped wiper die which has a receiving channel. A non-rotatable disc-shaped support tab is securely fixed to the wiper die and projects between the first and second tool members. The support tab has a circumferential cradle which is configured to match a contour of the tubular member and to merge into the receiving channel of the wiper die in a tangential and smooth manner. An outer clamping jaw is jointly pivotable with the bending tool, and a trough-shaped resistance member is placed in opposition to the wiper die and movable longitudinally along the receiving channel.

  • Patent number: 7981332
    Abstract: In a method for producing a composite, a carrier component is placed into an opened cavity of a mold. The mold is then closed to a predetermined position, thereby creating a cavity of a first expanded size. To improve venting, a vacuum is generated in the expanded cavity before filling the expanded cavity with a flooding material. A compression step is then executed either at the same time as flooding material is introduced or following the introduction of the flooding material.

  • Patent number: 7973436
    Abstract: In the field of electrical linear motors, it is known to make more than one laminate core (20) having teeth (22), wherein grooves (24) are designed between the teeth (22). Until now, coils assigned to the laminate core are arranged on each laminate core. The invention is based on this background. Instead, each coil (18) is arranged with a first section in a groove (24) of a first laminate core (20a) and with a second section in a groove (24) of a second laminate core (20b). The coils are consequently wound in an entirely different direction and now lie in a plane perpendicular to the direction of movement of the secondary part of the electrical linear motor.

  • Patent number: 7972439
    Abstract: In a method of growing single crystals from melt, the starting material is fused and a single crystal is pulled by crystallization of the melt on a seed crystal with controlled removal of the crystallization heat. Independent heating sources constituting thermal zones are used and constitute two equal-sized coaxial thermal zones which make up a united thermal area for the melt and the single crystal being grown and are separated by the melt starting material being carried out by heating the upper thermal zone with a heater 30-50% of power required for obtaining the melt, until in the upper thermal zone maximum temperature is reached The remaining power is supplied to the lower thermal zone to a lower heater with maintaining constant temperature of the upper thermal zone till complete melting of the charge. Single crystal enlargement and growing is conducted with controlled lowering of temperature in the upper thermal zone.
