Abstract: The present invention relates to an automatically operating gear mechanism, wherein varying speed ratios between a driving shaft (1) and a driven shaft (2) are obtained via a rotor (3) which is rotated by the driving shaft (1) about an axis of rotation (4) and which has weights (5) that are excentrically mounted relative to axes of rotation (6) about which they are provided to rotate, whereby said weights (5), by the rotation of the rotor (3), circle about the axis of rotation (4) of the rotor (3) and whereby the rotational movements of the weights (5) about their axes of rotation (6) are transmitted to the driven shaft (2) via a toothed transmission gear (7). For e.g. eliminating substantial effect limitations in such a gear mechanism or device, the axis of rotation (6) about which each weight (5) rotates, extends at a right angle ( alpha ) or at a substantially right angle ( alpha ) relative to the axis of rotation (4) of the rotor (3), whereby the mass of the weights (5) twice per revolution is diposed farther away from the axis of rotation (4) of the rotor (3) than otherwise, so that the force generated by the rotation of the weights (5) culminates twice per revolution.

Abstract: An arrangement performs rapid action sequences for a weapon part 11. The arrangement works with controlled acceleration and/or retardation of the movement sequence. A gable part is connected to and sealed in relation to an end portion of a cylinder part. The cylinder part projects into the gable part with a tubular portion to form, outside the space 5a of the piston, an outer space 5 which is connected to the piston space via a gap 7. The latter can be closed and opened by the piston when the latter moves closer to or further from an end position space 5a' formed by means of the gable part. A non-return valve function is arranged at said end position space so as to make possible on the one hand controlled retardation when the piston enters the end position space and on the other hand a controlled initial acceleration sequence for the piston when the latter is moved from the end position. The ports and the gap are designed with large areas so as to make possible large outflows and inflows of medium and thus high acceleration and speed of the piston. <IMAGE>

Abstract: A device for automatically controlling the operation of a door (10) with a vertically adjustable door leaf (14) detects the presence of an object (22) moving towards the door (10) to pass therethrough. In response to this detection, the door (10) is opened. A first sensor means (24) detects the height (H) of the object (22) approaching the door (10) and emits a first signal (S1) representing the detected height (H) of the object (22). A second sensor means (34) responds to the opening movement of the door leaf (14) by continuously emitting a second signal (S2) representing the current degree of opening (h) of the door leaf (14). A signal-processing means (32) receives the first signal (S1) and the second signal (S2) to compare the detected height (H) with the current degree of opening (h) of the door leaf and, in response to the result of this comparison, steplessly guides the door leaf (14) towards a stop position in which its degree of opening (h) corresponds to the detected height (H) of the object (22).

Abstract: The present invention concerns an ignition lock with blocking mechanism, in particular for motor vehicles with automatic gearboxes for preventing the ignition being switched off if the gear change lever is not in the park position, whereby the ignition lock comprises an outer lock cylinder (1) with a slot (26) for an ignition key, and the blocking mechanism comprises a sliding body (2) which, via a mechanical connection element (3), can be caused to take up different positions depending on the position in the gear change gate or the like as well as cooperating means (4, 5) between said lock cylinder (1) and said sliding body (2), which means only allow positioning of the lock cylinder (1) in the ignition switch-off position if the sliding body (2) is located in a particular predetermined position, which position corresponds to the park position for vehicles with automatic gearboxes. The construction of the invention is cost-minimising and increases the reliability since it involves a minimum of moving and separately manufactured parts.

Abstract: The lid (2) in the closed position rests on projection (6) arranged on frame (3) inside. The hinge arrangement can be turned around a part of its outer edge or inside to an open unstable position, in which position it has to be retained so that it does not, under the influence of forces of gravity, return to its closed position. The arrangement comprises at least one hinge (9) with two rectangular arms (19,11) located on each short side around a common axis. A first arm is movable across the axis between two end positions in a track issuing on the underside of the lid. The other arm is movable from a stop position across the axis in a track issuing in the body opening and arranged on the frame wall inside. The hinge with its other arm (11) in the stop position restricts the lid opening to the unstable position.

Abstract: An optical amplifier device intended for WDM light signals comprises a preamplifier (3) and a power amplifier (11) of the optical fiber amplifier type, which are connected in series and have gain curves dependent on the wavelength. A controllable attenuator (5) is connected between the amplifiers (3 and 11) and is controlled by a control device (7). The signal input to the preamplifier (3) has a low power and is amplified to provide an output signal where the signals of the input channels have been amplified with different gains. The input signal of the power amplifier (11) then has a larger power resulting in a gain characteristic different from that of the preamplifier (3). By adapting the attenuation of the attenuator (5) for variations in the input signal the gain characteristic of the power amplifier (11) can be set so that the signal output from the amplifier device has a spectral dependence that is the same as the original spectral dependence obtained without variations. Also, the same spectral dependence can be maintained when the pump light power of the power amplifier is changed and then the total amplifier gain is changed, by adapting the attenuation of the attenuator (5) so that the gain of the power amplifier is not changed. In the amplifier the lower possible noise from the preamplifier stage is added to the input signal and the full output power is always available from the power amplifier. If the input signal is e.g. increased the SNR of the signals passing through the amplifier is correspondingly improved. This improves the performance of an optical network in which the amplifier is used.

Abstract: An abrasive machine for grinding material from an outer surface of a workpiece. The machine includes a rotationally driven casing having an opening at one axial end thereof. The opening is defined by an annular edge which constitutes a grinding wheel. A shaft is disposed within the casing and forms a space whose center axis is offset from the center axis of the casing. Disposed within the space and supported by the shaft is a clamping mechanism which holds the workpiece within the plane of the annular edge. By turning the shaft relative to the casing, the clamping mechanism and the workpiece will be moved toward or away from the path of travel of the annular edge, due to the eccentric relationship between the casing and the space.
