Title: Permeable membranes for enhanced gas separation
Inventor: BIKSON BENJAMIN
IPC: B01D69/08
Filed: 1988-07-29
Granted: 1993-07-13
Abstract: PERMEABLE MEMBRANES FOR               ENHANCED GAS SEPARATION               Abstract of the Disclosure Composite membranes are prepared by depositing a separation layer on an asymmetric support layer.  The separation layer has a selectivity equal to or greater than that of the material of the asymmetric support layer for a desired gas separation.  The support layer is desirably produced in non-asymmetric form, and exposed to an elevated temperature approaching the glass transition temperature of the support layer material under non-swelling conditions to modify the structure thereof to create asymmetry therein, before or after the deposition of the separation layer, and to increase its compaction resistance and collapse pressure.  Such desirable properties are conveniently achieved on a repeatable basis, enhancing the uniformity and reliability of the treated support layer and of composite membranes produced therefrom, for use in gas separation operations.

Title: Method and apparatus for isolating faults in an antenna system
Inventor: HILL GORDON S
IPC: G01R31/08
Filed: 1988-09-13
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE    To isolate a fault in a radar system, prior art teaches the disassembling of many of the components of the radar system and, by means of trial and error, substituting each component and testing the complete radar system to determine if the substitution was correct. In the present invention, the transmission path of the radar system is divided into a number of sections, with each section being independently connected to an adapter. After a section has been connected to an adapter, a resistive load having an impedance matching that of the antenna is mated to the adapter.  Subsequently, a pulse is outputted from the transmitter of the radar system and transmitted along the transmission path.   If the transmission path between the transmitter and resistive load is without fault, then the signal reflected from the resistive load and measured by a VSWR meter near the transmitter would be below a predetermined threshold, as the resistive load substantially attenuates the power of the outputted pulse.  On the other hand, if a fault does reside within the transmission path, then the power of the reflected signal would be at or above the predetermined threshold.   By connecting the adapter to successive sections of the transmission path and by repeating the process of connecting the resistive load to the adapter and sending a pulse to the resistive load, a fault can be easily isolated.

Abstract: USER TO NETWORK INTERFACE PROTOCOL FOR PACKET COMMUNICATIONS NETWORKS          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. A special network protocol for implementing these features is controlled by data in the header of packets for the network.

A method of and apparatus for recording a first and a second EFM-modulated signal is described, which signals comprise EFM-subcode frames, the beginning of each EFM-subcode frame being marked by a subcode-synchronisation signal. In the track portion of a record carrier (1) intended for recording position-synchronisation signals are recorded by means of a track modulation which can be distinguished from the information pattern to be formed. During recording the subcode-synchronisation signals are maintained substantially in phase with the position-synchronisation signals (11), so that the track portions (14) in which the subcode-synchronisation signals are recorded substantially coincide with the track portions (140) in which the position-synchronisation signals are recorded. Recording of the first EFM-modulated signal (142) ends at a boundary position (144) which is situated at a predetermined position between the track portions (140) in which two successive position-synchronisation signals are recorded. Recording of the second EFM-modulated signal (143) begins substantially at the predetermined boundary position (144).            (Figs. 1 + 11c).

Abstract: TEXAS INSTRUMENTS LIMITED                           ABSTRACT            A Semiconductor Switching Device A semiconductor switching device that is suitable for use as a remote isolation device (RID) in telephone networks.  The semiconductor switching device is a two-terminal voltage sensitive device that switches from an open-circuit condition to a short-circuit condition at a fixed breakover voltage, appears as an open-circuit below the breakover voltage, and appears as a short-circuit above the breakover voltage.  When semiconductor switching devices are installed in a telephone network, they are held in their short-circuit condition by the network voltage supply and do not affect the normal operation of the network but will switch to their open-circuit condition if the network voltage supply is reduced to below the breakover voltage, and therefore, parts of the network may be isolated from each other by reducing the voltage supply.  Isolation of the parts of the network from each other facilitates testing for maintenance purposes.
