Title: Method and determination device for the implementation of the method for determining a connecting path in a communication network
Inventor: LIEBL ROBERT
IPC: H04Q3/66
Filed: 1998-12-29
Abstract: The invention relates to a method for establishing a suitable connection path in a communications network and to a corresponding switching device (1). When a connection request is made in relation to a desired destination node, a check is carried out to determine whether a suitable connection path to the desired destination node has already been stored in a corresponding dynamic memory (5). If this is not the case, a suitable connection path is determined using the stored network data of the communications network and then entered into the dynamic memory (5). This connection path is then available for responding to other connection path inquiries. Once a suitable connection path to the desired destination node has been established, the connection is set up according to this connection path.

Abstract: A method for obtaining an immune response to a non-enteric pathogen antigen (NEPA) such as hepatitis B surface antigen (HBsAg) by feeding the antigen in a plant material to an animal that is immunoreceptive to the NEPA. It has now been discovered that the animal may be made immunoreceptive to the NEPA such as HBsAg by prior primary immunization. When the animal is made immunoreceptive by a prior, e.g. primary, immunization, an immune response to the NEPA may be boosted in the animal by feeding the animal the plant material containing the NEPA. For example, an animal, e.g. a human, that previously had a positive response to primary immunization against hepatitis B, can have a booster response to HBsAg by feeding the animal the antigen in a plant material. The plant material is a substance comprising a physiologically acceptable plant material, especially potatoes, containing the NEPA, e.g. hepatitis B surface antigen (HBsAg). The NEPA, e.g. HBsAg in the plant results from expression by the plant of the NEPA due to genetic alteration.

The cooling chamber (10) comprises at least one cooling element (10a), which in turn comprises at least one inlet chamber (10b) and at least one outlet chamber (10c). The fiber web (5) with at least one felt or wire (3, 4) is arranged to run through a drying zone defined by the bands (1, 2) such that the fiber web is in contact with the surface of the first, heated band (1) and the felt or wire (3, 4) is between the fiber web (5) and the second, cooled band (2). The pressure of the cooling element (10a) is balanced by pressure balancing means, and the second band (2) is provided with a bearing. Since this pressure does not vary, the cooled band and the bearing of the band are better controlled.

Abstract: Expanding the data carrying capacity of a forward control channel of a cellular mobile radiotelephone (CMR) system.  By utilizing data fields that would otherwise be unused in a conventional data message system, an operation identifier can be transmitted to a data reporting device. The forward control channel carries control messages which are capable of causing cellular devices to perform certain communications functions.  An Order Code data field within the control message defines the functionality of the message. By utilizing the Order Code data fields to invoke the message waiting functionality of the control message, and replacing the message waiting data with an operation identifier, the data carrying capacity of the forward control channel is increased. An external device connected to the data reporting device can be caused to perform an operation defined by the operation identifier. The operation identifier can define an operation specified from a list of available operations.  For cellular communications devices that are responsive to more than one mobile identification number (MIN), the range of operations that can be processed by a control unit is greatly expanded.
