Abstract: A network for transferring data packets has at least two basic networks, each with a central station and a limited number of user stations. The respective central station connects the associated basic network to other basic networks. The data packets are transferred over a set of channels with the frequency-hopping method and the channels are in this context selected for data transfer in accordance with at least one frequency-hopping pattern in temporal succession. A separate frequency-hopping pattern that is orthogonal to the frequency-hopping patterns of immediately adjacent basic networks is processed in each basic network.

Abstract: A printer or copier has a developer station with a toner dispenser in which the toner is fed from a toner box to a transverse transport above a dosing apparatus. The transverse transport includes a helix driven by a drive mechanism. The helix has a pitch H that varies along its length or a thickness D that varies along its length so that the speed of conveyance in the transverse direction decreases over the conveyance path. The rotational speed of the helix is variable by adjustment of the effective length of a drive arm or an extent of an eccentric.

Abstract: The positions of a gear selecting lever in a combined automatically and manually shiftable transmission which is installed in the power train of a motor vehicle are monitored by a first sensor which transmits signals to a control circuit serving to initiate the operation of an actuator for the gear selecting lever. Certain positions of the lever are monitored and reported to the control circuit by one or more additional sensors which influence the operation of the actuator in the event of failure of the first sensor. One of the additional sensors can monitor a first range of positions of the lever including the position when the transmission is shifted into reverse gear, and another additional sensor can monitor a second range of positions of the lever including the position when the transmission is in neutral gear.

Abstract: The invention relates to a gas generator, comprising a first gas-generating stage and at least one gas-generating stage arranged downstream of the first stage, and also comprising a device for detecting a pressure change in the gas generator, wherein the device for detecting the pressure change comprises a chamber divided by a movable part into two partial chambers which are gas-tight with respect to each other, the partial chambers having openings which are in flow connection with the first stage and each have different cross-sectional areas, so that the pressure change spreads at different speeds in the two partial chambers and brings about a movement of the movable part, and the movable part being connected with a movement meter, which due to the movement of the movable part generates an electrical impulse to activate the second stage.

Abstract: A belt buckle for vehicle safety belts has a load bearing frame and a locking mechanism thereon. A housing encloses the frame and has an insertion slot for an insert tongue acting in conjunction with the locking mechanism. To eliminate any extraneous matter that has entered into the housing through the insertion slot, a channel leads from the insertion slot through the housing and out of the housing, forming a guide for gravity assisted movement of such extraneous matter out of the housing.

Abstract: A belt retractor for a vehicle safety belt comprises a frame, a belt spool rotatably mounted in the frame, a locking catch arranged on the belt spool, a locking mechanism adapted to pivot the locking catch between an initial position and a locking position, a locking disc and a locking toothing. The locking toothing is arranged on the locking disc. The locking catch when in the locking position engages into the locking toothing of the locking disc so that the belt spool is locked with respect to the locking disc. The locking disc is connected to the frame by means of a holding device which allows a rotation of the locking disc relative to the frame only after a predetermined torque has been exceeded.

The apparatus is also provided with a sensor for detecting a temperature of the internal combustion engine and a consumer control device associated with a consumer of electrical power. The apparatus is further provided with a power flow controller which controls the consumer control device such that a portion of the energy stored in the energy storage device is delivered to the consumer of electrical power before the electric starter is supplied with power. The portion of the energy has a size which is dependent upon the sensed temperature. The size of the portion is smaller at low temperatures than at high temperatures.

Abstract: A method for multicolor electrophotographic printing includes a photoconductive layer system having surface elements or surface regions that are provided with an initial negative potential, then are exposed to varying degrees and developed with negatively charged toner particles of a color. A uniform light source is arranged closed to the photoconductive layer system and then the surface elements are developed with a second color toner. In particular, the image being printed has image elements of different colors which correspond to different surface elements of the photoconductor. These surface elements are differently illuminated to achieve different potentials and are developed by color particles by depositing the color particles on the respective surface elements. The charge potential of ones of the surface elements is increased and then surface elements not covered by color particles are illuminated to reduce the charge potential there prior to subsequent development of further surface elements.
