Abstract: A ship propulsion (3) with at least a fixedly positioned transmission unit (4, 204) secured to the hull (6) of the ship and a propulsion unit (5, 205) located on the exterior of the hull. The ship propulsion (3) facilitates pivoting of the propulsion unit (5, 205) around a control axis (10, 110, 210, 310), via a control device (200, 300). The control device has a control motor (120, 220, 320) and at least one control transmission (130, 230, 330). The control transmission is designed as a reduced planetary transmission, which comprises two central gears (131, 132, 231, 232, 331, 332) and a planetary gear carrier (233, 333, 433) with at least two planetary gears (238, 338), and coaxial positioned with reference to the control axis.

Abstract: A planetary gear train having planetary gears (8) which are rotatably mounted on a planet carrier (18) and are in toothed contact with an internally toothed ring gear (14) and a sun gear (4). For a simplified, process-safe and inexpensive backlash of the planetary gears (8) without axial displacement of the sun gear (4), the ring gear (14) and the planetary gears (8) are conically designed so that planetary gear axles (16) are retained in the planetary gear carrier (18) at an inclined angle (a) and that the planetary gears (8) are axially movably disposed upon and coordinated with the planetary gear axles (16) and the position of the planetary gears (8) can be adjusted within the planetary train by adjusting mechanisms for adjusting a backlash.

Abstract: A shaft-hub connection between one shaft segment comprises one central toothed segment, the same as adjacent centering segments and one stepped hole in a hub, in which the shaft and the hub are jointed in axial direction and by the toothed shaft segment a positive fit is formed with the hub, in which the front centering segment, lying in joint direction, has a diameter d1 and the toothed shaft segment, the same as the rear centering segment lying in joint direction, has a diameter d2 larger than d1. It is proposed that the hole has only two adjacent segments I, II of different diameters D1 and D2, that the diameter d1 in the centering segment with the diameter D1, the same as the diameter d1 in the centering segment with the diameter D2, form a respective joint fit and the diameter d2 in the area with the diameter D1 forms the positive fit.

Abstract: An improved motor vehicle roof is provided which includes a roof opening provided in a fixed roof surface, at least one closing element for selectively at least partially closing the roof opening, an electrical adjusting drive for driving the closing element and a sensor engineering system for detecting a situation which adversely affects the safety of the passengers and for producing a corresponding danger signal. Importantly, the roof includes a quick-action closing device coupled to the sensor engineering system which causes the closing element to close from its open or partially open position when a danger signal is present. The closing device includes means for producing an electrical voltage which exceeds the normal feed voltage (rated voltage) of the adjusting drive by several times, and for applying the voltage to the electric adjusting drive.

Abstract: The planetary gear according to the invention comprises a sun gear (2) connected to a driven central shaft (20), a ring gear (12), a group of first stepped planetary gears (8, 10) and a group of second stepped planetary gears (4, 6). The large step wheels (4) of the second stepped planetary gears engage the sun gear (2), the small step wheels (6) of the second stepped planetary gears simultaneously engage a pair of adjoining large step wheels (8) of the first stepped planetary gears and all small step wheels (10) of the first stepped planetary gears engage the ring gear (12). The gear allows for high transmission ratios having a small size and low inertia moment and offers excellent properties in relation to efficiency and transmission reliability.

Between two planet wheels (10) is provided each time an intermediate shaft (6) and each shaft has two sets of teeth (7, 8), the smaller set of teeth (8) being provided for simultaneous engagement with two adjacent planet wheels (10) between which the intermediate shaft (6) is situated, and the second set of teeth (7), the reference circle of which is larger than that of the first one, engages with the central sun wheel (1).

Abstract: A planetary gear (1) in the form of a Wolfrom gear with a high transmission ratio. Such gears are preferentially used in handling gear engineering. In order to reduce the number of components required and improve the overall efficiency of the planetary gear, the step wheels (4, 6) of the step planet wheels (5) or the hollow wheels (11, 12) are conically toothed and have opposite conical inclinations. The planet carrier (10) is floating, that is, without a separate bearing. The planetary gear is used especially in industrial robots.

Abstract: A planetary gear having step planet gears is generically a Wolfrom gear which permits large ratios. Transmission of this type are used mainly in the handling technology. In order to improve the portability, friction, vibration and noise characteristics, step planet gears with separate toothed regions of the step gears are used. The modules of the step gears are graduated. The number of teeth is identical. Each of the teeth engagements with the ring gears can be optimized. The teeth on the step gears are preferably honed.

Abstract: A magnetic recording medium consisting of a flexible layer support and a magnetic layer consisting predominantly of magnetic particles finely divided in a binder and nonmagnetic additives applied to the layer support is obtained with improved orientation of the magnetic pigments by adding a dispersion stabilizing component to the magnetic dispersion at a uniform rate over the whole period of dispersion. Highly purified lecithin or a mixed ester of a polyethoxy phosphate ester or ethylene diaminodistearate, a polyurethane resin containing sulphonate groups or a vinyl chloride/vinyl alcohol copolymer is preferred as stabilizing additive.

Abstract: This invention relates to an arrangement for determining the degree of dispersion of magnetic pigments in a dispersion, in which the magnetic dispersion flowing along a transparent tube or a transparent wall is irradiated with an illuminating and image forming device and the light diffusely reflected from the dispersion is measured in a detector as to its color and/or brightness and indicated in an evaluating device.

Abstract: A Venturi Cooler for flue gas desulphurization devices sprays water through water spray nozzles on pipes positioned perpendicularly to the longitudinal flow direction of the cooler. It is important for the effectiveness of the diffused water that the speed of the flue gas does not fall below a certain limit. A simple adjustment of the cross section of the Venturi cooler to the respective flue gas amount can be achieved by arranging movable baffles on the pipes. The baffles are positionable to reduce the cross section of the Venturi cooler and leave the openings of the water spray nozzles free. They advantageously comprise rotatable sleeves surrounding the pipes and have rotatable flaps for fast adjustment of the cross section.
