Granted: 1993-12-14
Abstract: Abstract A process for manufacturing open porous sintered bodies with a large open pore volume and defined pore diameters and which at least predominantly consist of glass-cera-mics. They are obtained by sintering a mixture of sinte-rable powder and an inorganic soluble salt with defined grade of grain, the melting point of which is above the densification temperature of the sinterable powder. For the formation of a molded body the mixture of sinterable powder and inorganic salt is submitted to a molding process. The molded body is sintered in a sintering process and the soluble salt being contained in the molded body is lixiviated. As a main constituent the sinterable powder contains a pulverized crystallizable glass powder. The sintering process is performed in such a way that the crystal phases being produced during the crystallization of the crystallizable glass, and therefo-re the material properties, too, are controlled by the guidance of the sintering process as well as by the ion exchange taking place between the sinterable powder and the inorganic salt and which is controlled by their composition. Afterwards, the sintered body is transformed to the final glass-ceramic texture.

Title: Architecture of the control of a high performance packet switching distribution network
Inventor: ROEDIGER GARY A
IPC: H04L12/56
Filed: 1988-11-23
Granted: 1993-08-31
Abstract: ARCHITECTURE OF THE CONTROL OF A HIGH PERFORMANCE PACKET SWITCHING DISTRIBUTION NETWORK Abstract A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides, security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.

Granted: 1992-12-01
Abstract: TRUNK DIALING CONVERTER         Abstract A digital FSK trunk dialing converter including M and E  lead control  is  disclosed.   The dialing converer further includes an FSK detector which is responsive to consecutive  half period  intervals  of  a  received  FSK signal,  and a digital signal-to-noise  (S/N)  detector or estimator which operates  to  inhibit  or  keep the E-wire signal lead deactivated in the presence of noise signals which are received from the communications link in absence of acceptable FSK signals.  The FSK detector is comprised of two digital circuits which generate pulses indicative of whether the received FSK signal is greater or less than the FSK center frequency.  The pulses are integrated and used to trigger a flip-flop which provides a demodulated digital FSK output indicative of a received high or low FSK  analog frequency.   An  E-wire  control  signal  is generated in the receive logic circuitry in response to the demodulated FSK output.  The S/N detector comprises a digital  circuit  coupled  to  the  FSK  detector  and  is responsive to  the pulses  generated  thereby  to  generate reset signals which are coupled to logic circuitry when noise signals are received to prevent the generation of an E-wire signal when noise is present.
