Abstract: Different commercial messages are broadcast to different demographically targeted audiences in a cable television system or the like. A first television channel contains television programs and periodic commercial messages. A second television channel contains alternate commercial messages. Demographic characteristics of a viewer are identified, and commercial messages are selectively provided from the first or second channel, depending upon the viewer's demographic characteristics. Demographic data can be input by a viewer via a remote control, downloaded to a subscriber's converter from a remote headend, or programmed into the converter at installation. Prioritization of the demographic characteristics of a plurality of television viewers watching a program together enables commercials to be targeted to the viewer having highest priority. Statistical data can be maintained concerning the number and identity of subscribers viewing specific commercials.

Abstract: A communication network has one master node (16) which maintains an active master list (AML) containing the node addresses of all nodes (12-16) to which the token will be passed. When nodes are added or deleted from the network, it is efficient in terms of data bus occupancy and individual processing time by the nodes if the successor address for each node is broadcast in a single message, and the availability of an AML makes this possible. The network has the capability of efficiently updating the AML whenever the configuration of the network is so changed.

Abstract: A multicomponent fluid separation and irradiation system is described containing a centrifuge drum and a source of radiant energy (2) located within the drum. In a first embodiment a disposable rigid separation/irradiation chamber (14) is provided with a cylindrical outer compartment located within the drum and opposing the radiant energy source (2). Whole blood is supplied to the chamber through a dynamic seal (60) located at the center of the chamber. As the chamber is rotated, blood is separated so that energy from the source (2) passes through the inner wall (16) of the chamber and the separated plasma layer to irradiate the buffy coat layer (24). In a second embodiment, one or both of the walls of the outer compartment of the chamber are flexible so that the chamber will expand as blood is pumped in and will collapse as blood is pumped out.

Abstract: Speech digitising is carried out using both signal form coding and source coding with a coder for digitisation and a decoder for reconstruction of the speech signal. The speech signal is divided up into segments in the coder and processed in one part of the segments with an approximation of the sampling values which is as accurate as possible, where an estimated value is calculated for pending sampling values using known sampling values. In the other part of the segments, parameters for speech simulation in terms of the source coding only are derived. The individual signal segments are processed at variable bit rates which are allocated to different operating modes, and each signal segment is categorised as one of the operating modes. The individual speech segments are thus coded according to requirements with a larger or smaller number of bits, providing a hybrid coding method which unifies the source coding and the signal form coding. Along with the signal quantisation of preceding and subsequent signal processing stages, this produces an average bit rate of 6 kbit/s and a speech quality which corresponds totally to that of telephony transmission. <IMAGE>

Abstract: The invention provides a method and apparatus for the manufacture of helically wound paperboard tubes having a highly uniform outside diameter. The method of the invention involves the application of controlled compressive force to at least one of the paperboard plies fed to a helical winding operation in order to control the thickness of the ply or plies and thereby control the outside diameter of the helically wound tube. In one preferred apparatus embodiment of the invention, the compressive force applied to the paperboard ply is applied via a pair of cooperating compression rolls. The nip between the two cooperating rolls is controllably varied by mounting one of the rolls for rotation about a shaft which is rotatable about an eccentric axis which is parallel to and offset from the axis of rotation of the roll. The rotation of the shaft thus causes the roll to move toward or away from the other cooperating roll and thereby varies the nip spacing between the rolls.
