  • Patent number: 9083689
    Abstract: A system, apparatus, method, and machine readable medium are described for implementing privacy classes within an authentication framework. For example, one embodiment of a method comprises: transmitting a query for client information from a server to a client, the client information including information related to authentication devices coupled to the client; analyzing the query to determine an appropriate privacy class to be used for providing client information to the server; providing a subset of client information selected based on the determined privacy class, the subset of client information including the information related to the authentication devices coupled to the client; and using the subset of client information within an authentication framework to provide user authentication services over a network.

  • Patent number: 6782890
    Abstract: The distributor of a cigarette rod making machine employs a zig-zag sifter which receives a mixture of tobacco ribs and shreds from a reservoir by way of a duct or an elevator conveyor. The shreds leave the uppermost stage of the sifter and are conveyed, by a Coanda separator, into an upright gathering duct which discharges shreds for delivery onto the concave surface(s) of one or more guides serving to direct one or more streams of shreds against the underside(s) of one or more foraminous belt conveyors which advance the stream(s) past one or more trimming devices serving to remove the surplus and to thus convert each stream into a rod-like filler which is ready to be draped into a web of cigarette paper. The removed surplus is returned into the reservoir or directly into the zig-zag sifter.

  • Patent number: 6634365
    Abstract: A shower of tobacco particles is fed into the upper end of a downwardly sloping and downwardly tapering funnel-shaped part of a conveyor wherein the particles gather into a flow of interlaced particles. Successive increments of the flow are acted upon by one or more jets of air issuing from at least one nozzle which loosens successive foremost increments of the flow prior to admission into a tobacco filler rod forming unit in a cigarette rod making machine.

  • Patent number: 6170489
    Abstract: The carding at the periphery of a driven wheel in the distributor of a cigarette rod making machine receives tobacco particles from the lower portion of a substantially upright duct the upper portion of which can receive tobacco particles from a magazine by way of an elevator conveyor. At least the lower portion of the duct is vibrated (e.g., at an amplitude of approximately 6 mm and at a frequency of 15-25 Hertz) in directions at right angles to the horizontal rotational axis of the wheel to thus enhance the homogeneousness of the carpet of particles being transported by the carding beyond the discharge end of the lower portion of the duct.

  • Patent number: 5347853
    Abstract: The reliability of mechanical testing of the hardness of cigarettes with one or more pivotable weights is enhanced by modifying the results of such testing on the basis of signals which are obtained by optically scanning the diameters of successive cigarettes prior to mechanically induced deformation. Optical scanning is carried out by triangulation with a fixedly mounted measuring head. The signals which are obtained with mechanical testing can be further influenced by taking into consideration the moisture content and/or the temperature of tobacco in tested cigarettes.

  • Patent number: 5301011
    Abstract: The diameters of rod-shaped articles of the tobacco processing industry are ascertained while the articles are transported past a measuring station in the flutes of a drum-shaped conveyor moving along a range finder which measures the distance of each article of a series of articles from a reference point and transmits appropriate signals to an evaluating circuit wherein the diameters of successive articles are determined on the basis of comparison with a fixed reference distance of the bottoms of the flutes from the reference point. The beam of radiation which is emitted by the radiation source of the range finder is reflected by successive articles, and the intensity of reflected radiation is used to generate second signals which are processed into signals denoting a second diameter of each article. A third diameter of each article can be ascertained downstream of the range finder by an optoelectronic detector.

  • Patent number: 5012825
    Abstract: Apparatus for perforating a running web of wrapping material, such as a web of tipping paper in a filter tipping machine for the making of filter cigarettes, is advanced through two successive electric perforating units one of which is active while the other is idle, and vice versa. This renders it possible to clean the perforating electrodes of the idle unit while the electrodes of the active unit produce sparks which remove fragments of material from the web to form one or more rows of perforations and to thus influence the permeability of the web. The apparatus can be installed in a filter tipping machine between a reel for a supply of convoluted web of tipping paper and a severing device which subdivides the leader of the perforated web into uniting bands serving to connect pairs of plain cigarettes with filter mouthpieces of double unit length.
