Abstract: For encrypting a string of data elements from a first value range, a respective data element is combined with a key element by a first computing operation. The resulting combination result may lie outside the first value range. From the combination result, an encrypted data element is then derived by a second computing operation that maps onto a second value range, for example printable 1-byte characters. Decryption is accomplished by combining the encrypted data element with the key element using an inverse computing operation to the second computing operation executed iteratively until a result of an iteration step lies within the first value range.

Abstract: A method of transporting rod-shaped tobacco smoke filters, which carry solid particles, along an elongated path from a sender to a receiving station, includes transporting the filters from the sender to the receiving station through the predetermined portion of the path. A plurality of jets of a pressurized gaseous fluid is directed across a predetermined portion of the path to expel from the portion of the path solid particles which are separated or separable from the filters. The expelled particles are collected in a chamber outwardly adjacent the predetermined portion of the path. The collected particles are evacuated from the chamber.

Abstract: A method and arrangement are provided for producing compound filters for products in the tobacco-processing industry. A filter tube, having a filter element in a central region of the filter tube, is supplied to a predetermined position. Predetermined portions of filtering material are then inserted into the filter tube from at least a first end of the filter tube so that filter segments form in at least a first part of the filter tube.

Abstract: Apparatus for transporting rod-shaped tobacco smoke filters, which contain and/or carry particles of charcoal and/or other particulate tobacco smoke filtering and/or flavoring material, wherein a sender directs a series of successive filters lengthwise into a pneumatic conduit extending toward or into a receiving station. A section of the conduit ahead of the receiving station is provided with openings communicating with a collecting chamber. A duct which extends along the section of the conduit is provided with orifices serving to direct jets of a pressurized gaseous fluid into the openings to thus expel loose particles and/or particles adhering to the external surfaces of filters into the collecting chamber. The latter discharges collected particles by gravity flow.

Abstract: Apparatus for transporting rod-shaped tobacco smoke filters which contain and/or carry particles of charcoal and/or other solid particulate tobacco smoke filtering and/or flavoring material. A sender directs a series of successive filters lengthwise into a pneumatic conduit wherein the filters advance toward a receiving station. A section of the conduit has an arcuate shape and advances successive filters from a lower level to a higher level. The underside of the section has an elongated arcuate opening which is overlapped by a cover in such a way that any solid particles which became separated from the filters can be expelled into a neighboring chamber due to fluid pressure in the section as well as under the action of gravity and/or centrifugal force.

Abstract: A hanging file support apparatus having a rectangular top for receiving hanging file folders. The top contains circular support rods of identical cross section fitted into modular cornerpieces having three orthogonal extensions for receiving the rods. A pair of clip-on dividers with a rod extending between them may be attached to the top. The top may be attached to the top edge or inside of a drawer or other workspace through holes in the cornerpieces. The top may also be supported by vertical support rods that are received by the cornerpieces. The vertical rods may be mounted into holes in a drawer, shelf or other workspace. Alternatively, the vertical rods may be mounted into a base comprised of cornerpieces and rods.

Abstract: An interior securing device for a lock of a movable vehicle body part of a motor vehicle includes a Bowden cable provided as a transmitting device which is rigidly connected with a securing knob and is linked to an adjusting element. The Bowden cable is surrounded along its length by a flexible guiding sleeve. Near the securing knob, the guiding sleeve is held fixed to the vehicle body part. Near the adjusting element, the guiding sleeve is held fixed to the lock. The securing device is particularly suitable for use with rear side doors of passenger cars.

Abstract: An internally or externally geared pump for conveying fluids lacking or only having insufficient lubricating ability, includes gearwheels moving in an operating chamber of the pump, conveying fluids and being mounted completely in parts formed of a carbon material. Supports are formed from accurately worked lateral walls and a jacket of the operating chamber formed of the carbon material. The jacket surrounds the gearwheels in the radial direction and is likewise constructed as a support. Chambers on the suction side and on the pressure side for fluid supply and fluid removal, which are necessary for the operation of the pump, are molded into side walls of the operating chamber which is formed of carbon.

Abstract: A soybean variety designated 93B82, the plants and seeds of soybean variety 93B82, methods for producing a soybean plant produced by crossing the variety 93B82 with itself or with another soybean plant, and hybrid soybean seeds and plants produced by crossing the variety 93B82 with another soybean line or plant.

Abstract: A natural circulation reactor, especially a boiling water reactor, includes a reactor pressure vessel, a reactor core and a core jacket disposed within the reactor pressure vessel, surrounding the reactor core and having at least one inlet port and one outlet port for core coolant. A flow path for the core coolant, which is formed between the core jacket and the reactor pressure vessel, leads through the inlet port into the core jacket and has a flow cross section. At least one throttle element is disposed in the flow path for varying the flow cross section in order to regulate the core coolant flow rate. The flow cross section can be both increased and reduced in size by varying the cross sectional area of the throttle element, so that a regulation of the power of the natural circulation reactor is carried out in a simple way and, in an incident, a reduction in power to approximately 40% of the instantaneous reactor power is ensured.

Abstract: Filter rod sections are transported sideways from a magazine containing a pile of parallel sections toward positions of alignment with the inlet of a pneumatic conveyor and are propelled into the conveyor at a transfer station where they continue to move sideways. In order to avoid damage to sections during propulsion into the conveyor, the duration of complete transfer of successive sections into the inlet is monitored in order to generate signals denoting the intervals of axial advancement of successive sections all the way into the conveyor. Such signals are compared with signals denoting those intervals of sidewise movement of sections past the transfer station during which the sections can move axially without being damaged by the stationary inlet of the conveyor.

Abstract: In an hermetically sealed fresh-keeping container for organic substances, in particular foodstuffs, with a dimensionally stable bottom part that incorporates a support surface for the goods that are to be kept fresh, a similarly dimensioned and stable upper part that is mounted on the lower part, above the support surface, so as to be removable. The hood forms a useable space, and a vacuum pump system removes the air within the useable space. The useable space is also delimited by an airproof foil, the edge of which is releasably connected with a wall of the container. A suction opening of the vacuum system is incorporated in this wall.

Abstract: Apparatus for transferring rod-shaped articles from the outlet of a magazine for parallel articles into the inlet of a pneumatic conveyor wherein the articles are moved in the direction of their longitudinal axes comprises a rotary drum-shaped conveyor having a peripheral surface provided with axially parallel flutes. When the rotary conveyor is driven, its flutes advance seriatim past the outlet of the magazine to accept discrete articles which are thereupon moved sideways toward alignment with the inlet of the pneumatic conveyor. A pneumatic ejector system is utilized to propel successive articles from their flutes into the pneumatic conveyor. The apparatus employs a hood having a concave surface which is complementary to a portion of the peripheral surface of the rotary conveyor.
