Patent EP-0380015-A2 (EP)
Inventor: RICHTER GUNTHER
IPC: B29C48/475
Filed: 1990-01-22
Abstract: The invention relates to a method for discontinuously manufacturing multilayered coextruded tubular preforms made of thermoplastics for forming large-volume, multilayered hollow articles in a split blow mould, in which at least two different, annular material melts are brought together centrally within the annular ram one after the other and in the direction of extrusion to form a multilayered material melt and in which this multilayered material melt flows outwardly in the shape of a funnel into an annular accumulating space and is subsequently discharged by an axially movable annular ram, which acts as a coextrusion head and is forced upwards by the multilayered material melt, via an annular die gap, so that the individual material melts are deflected out of their extrusion direction and flow radially into the corresponding flow channels before their entry into the coextrusion head. 
<??>In order to improve the known method in such a way that cross-sectional changes no longer occur in the transitional area between the respective extruder and the annular ram, so that weak points are avoided or are reduced to such an extent that they no longer have an adverse affect on the finished hollow article, it is proposed that the individual material melts are deflected out of their extrusion direction and flow radially into the corresponding flow channels of the annular ram before their entry into the coextrusion head.

Abstract: A computer network for real time control having redundant components for automated fault identification and automated bypass of identified faulty components. The system includes at least two main computers, each coupled to at least two independent parallel data channels. A plurality of satellite computer pairs are connected to these channels, each pair receiving information from a plurality of I/O racks which are connected to redundant sensors for detecting information and to redundant actuators for implementing system control. The main computers are continuously crosslinked and perform evaluation of their respective input and output streams comparing these streams for consistency between the main computers. In the event that an inconsistency is detected in the data streams, the system checks for faulty components to determine the origin of the inconsistency. The system utilizes an evaluation method whereby each main computer independently accesses each of the parallel data channels, satellite computers, I/O racks, sensors and actuators to locate inconsistencies in the data stream. The system then allows for operation with one of the redundant components while the identified defective redundant component is repaired or replaced.

Abstract: According to a prior patent application, the digital user data signal is transmitted in CMI code and, when the code is generated, a binary signal content of the auxiliary signal is allocated to one of the element combinations excluded according to the CMI code rule. Since only the start of a one bit or zero bit of the auxiliary signal is marked, pulses which severely impede the generation of a clock signal occur at the receiving end at comparatively large intervals only. According to a parallel application, a clock pulse pattern is therefore transmitted with sporadic data pulses. The described receiver is able to generate a new clock signal from the clock pulse pattern without the jointly transmitted data pulses being able to cause phase interference. The entire arrangement can be set up fully integrated in CMOS technology. <IMAGE>

Abstract: A computing system including a host processor and at least one intelligent subsystem having attached devices, has two interrupt ports. The one intelligent subsystem and the attached devices are each viewed as a logical device by the host processor, and each is assigned a device identification number. The host processor provides direct and indirect commands to the logical devices. For direct commands, first physical interrupts are provided to the host processor serially from the logical devices through an Interrupt Status Port. For indirect commands, logical interrupts are stored in predetermined bit positions in a Device Interrupt Identifier Port (DIIP) in accordance with the device identification numbers. A second single physical interrupt is provided to the host processor as long as there is at least one logical interrupt pending from at least one logical device as the result of an indirect command. The host processor reads the DIIP to determine which logical devices have at least one logical interrupt pending for an indirect command. A plurality of logical interrupts for a single logical device may be cleared with a single reset interrupt command from the host processor.

Abstract: The discrete Fourier transform is continuously calculated at input signal sample rate using recursive filtering, rather than transversal filtering. This reduces the number of complex digital multiplications per computational cycle to N, the number of spectral components in the discrete Fourier transform, where rectangular truncation window or a new exponential window is used. Where a triangular truncation window is used the number of complex digital multiplications per computational cycle is reduced to 2N.

Abstract: Traffic measurements and network management controls are applied in an exchange in real-time on a per-route basis. Selection of an idle circuit between two exchanges is done by first selecting a route and path based on a route busy/idle status map, a source destination restriction map defining restriction on a route for certain sources, and a second connection map defining availability of a second link in a two link connection. A circuit group busy/idle map for a selected route is consulted to find an idle circuit group and finally, a circuit is selected from a circuit group which is known to have at least one idle circuit. Traffic measurements, including measurements of attempts, seizures and answers are recorded on a per-­route basis with a specific indication as to the source of the traffic in the event of a direct route. Traffic measurements are also made to record traffic routed to an alternate route and the identity of the alternate route as well as traffic received as alternate route traffic from another route together with the identity of that route. Data defining routes and alternate routes which have a low completion rate are identified and network management controls are automatically applied to the routes for affected destination codes. Circuit reservation levels are defined which allow the selective control of alternate or direct traffic on a route based on the number of idle circuits in a route.
