Abstract: A rotor unit comprises a rotor cylinder which is fastened to a shaft and is rotatably supported via an external bearing. A gear motor is arranged in the interior, which gear motor drives a first double gear wheel in both rotating directions (a, b) via its power take-off shaft and a pinion. The double gear wheel is supported on a disk and a bearing plate in a freewheel bearing and engages with a second double gear wheel. In one rotating direction (b), the freewheel bearing locks the toothed wheel, so that the latter, rigidly together with the disk, is carried along by the pinion. In this way, the second double gear wheel engages serially with one intermediate gear in each instance, wherein every such engagement is exactly positioned by means of a ball catch. In the other rotating direction (a), the motor in each instance turns a number wheel via the aforementioned gears and accordingly sets e.g. one digit of the postage meter machine's value stamp.

Abstract: A label dispenser (10) includes a storage container (13) for labels (11). A withdrawal roller (15) is in contact with the labels (11) and is supported together with a gear-wheel pinion (17) and a free-wheeling bearing (19) at the storage container (13). The pinion (17) is engaged with a fixed-position gear rack (23). As soon as the finger pressure actuates the server plate (29), the storage container (13) is pressed downwardly, the gear-wheel pinion (17) rotates the withdrawal roller (15) such that the outermost label is pushed out downwardly out of the storage container (13). The outermost label is then gripped by a transport roller pair and can be transported off. As soon as the finger pressure is released, a helical spring (37) slides the storage container (13) back into the starting position. In this case, a hollow cylinder (33), together with an air valve (39) furnishes a braking of the speed, while the free-wheeling bearing (19) runs freely.

Abstract: A voltage control regulator features a power switch in the form of a transistor that is normally actuated for a constant switch-on time interval during each variable period interval (T). The type of control required in this case comprises, conventionally, a monostable multivibrator, a controller, and a voltage/frequency converter. The present control system is subordinated to an emergency control circuit which, via a priority loop, intervenes in the control process as soon as the current flowing through the switching transistor threatens to become excessive. This emergency control unit thus constitutes a predictive type of control that employs knowledge of the operation of the voltage control regulator and the instantaneous values of the input and output voltages of the voltage control regulator, in order to predict the voltage increase during the period interval (T). Such an arrangement permits the emergency control unit to react very quickly.

Abstract: A housing for electronic components that includes a tubular, extruded aluminum, mid-section, a flat or plate-like front panel and a die-cast double-domed rear wall. Arranged in one of the domes of the rear wall is a printed circuit board with first female plugs. Fitting through the second dome, from the outside, are second female plugs, to which outwardly-leading cables are attached. Circuit boards with integrated electronic circuits slide into the housing and are secured laterally by guide grooves integral with the middle section of the housing. The boards, at their frontal edges, make contact through their male plugs with the appropriate ones of the female plugs. The boards are further secured by fitting into notches in a reinforcement rib between the two domes. A strip having three contact points is secured, if desired, to each circuit board for the purpose of reducing mechanical vibration. Each circuit board can be replaced individually. For this purpose, withdrawal arms are provided.

Abstract: The power converter (10) serves for conditioning an electricity supply for a load (12), whereby the supply is derived from a power source (11) and is adapted to the requirements of the load (12) in respect of the electrical values. The converter (10) comprises in its simplest version exclusively a transformer (13) and an inductive resistor connected in series with the latter and designated as an actuator (14). This actuator (14) is constructed from two coaxially-arranged, identical and annularly closed variety cores (111, 112), which are individually surrounded by partial windings of an induction winding (150) and jointly by a control winding (117). The latter (117) is joined to a control system (30), which by means of a control current (I) sets an inductivity value (L) of the actuator (14), which can be varied within wide ranges (1.100).

Abstract: The invention relates to the sidestop (20) guides, in the separating device (10), in particular a device for feeding a franking machine, the respective pile (11) of letters to be franked, irrespective of their particular format, by the front part of their longitudinal edge. The stop (20) comprises a support (25) with two stop surfaces (21, 22) arranged at right angles. The support can turn through 90.degree. around a pin (29) in a counter-clockwise direction. Small envelopes are guided by one of the stop surfaces (21); larger ones are guided by the other stop surfaces (22) when the support (25) is rotated. The stop (20) can be moved perpendicularly to the direction of movement of the envelope and turned to a third working position in which it forms an additional stop surface for envelopes of very large dimensions.

Abstract: An inductive component for universal use in any electrical/electronic circuits, whose coefficient of self-induction (L) is independent of the signal, is constant, electrically controllable and can be varied significantly. The component (10) comprises two mutually independent, identical ring-shaped and self-contained ferro-magnetic cores (11, 12) which individually carry the partial windings (15.1, 15.2) of an induction winding (15) and jointly carry a control winding (17). The direction of coiling of the windings (15.1, 15.2, 17) is such that the magnetic fields produced by currents through the windings are mutually weakened, but in the other core (12) they are reinforced. The component (10) is connected via its induction winding (15) to a controlled circuit (25), and via its control winding (17) to a controlling circuit (27), or forms with its windings (15, 17) an element of this circuit (25, 27).

Abstract: The present invention provides a method for releasing and for controlled storage of a desired predetermined value into a preset value memory storage of a postage metering machine. Initial values are transmitted in each case from a postage metering machine to a release apparatus. A first key code word is determined by a first algorithm module section from initial values and from values stored in a first memory storage associated with the postage metering machine. A second key code word is determined by a second algorithm module section from initial values and from values stored in a visually readable table associated with a second memory storage in the release apparatus. The second key word is transmitted from the release apparatus to the postage metering machine, where it is stored in a storage memory section and compared with the first key word in a locked section of memory.
