Abstract: MODULAR SLOT INTERCHANGE DIGITAL EXCHANGE                  ABSTRACT OF THE DISCLOSURE    Up to k (e.g. 4) slot interchange memory/switch modules operate under common control to provide varied time inter-change connective pairing associations between space divided telephone and data lines and time divided channels of digital trunks.  A high scanning rate combined with dot-OR'ed (common-ed) busing of addresses and outputs of all interchange modules permits in-service expansion of interchange switching capacity, from the capacity of 1 module to that of k modules, with minimal re-work of existing circuits and common control programs.          The interchange slot locations of the aggregate array are thereby linkable in paired randomly ordered time interchange associations, over the entire addressing range of the aggre-gate.  Additional interchange spaces are available in each switch module for interchanging activity bits in association with information traffic.  These bits are useful for compand-ing control, echo cancellation, TASI and network routing.          Activity bits associated with input load  to individual trunks are processed to form a TASI mask for out-of-band transmission over a channel of the respective trunk.  Trunk channels are allotted to the traffic in accordance with respective bits of the mask.  If the input load exceeds the capacity of a frame the mask is structured to effectively free out (and cancel) part of the traffic load.  Traffic to be cancelled is selected in a predetermined order of priority favoring data over voice (talkspurt) activity and continuing talkspurt activity over initial talkspurt activity.  The selection is complicated due to the short time available between the sensing of potential overload and the transmission of the TASI mask.  Freezeout rates exceeding a predefined threshold are monitored and reported through the interruption facility of the common controls as an information parameter useful for high level network management.  A network management system linked to a network of such exchanges may thereby reconfigure "route" tables governing slot interchange assignments to balance trunk loads throughout the network. The slot interchange timing cycle and addressing capability are designed to permit establishment of line-to-line "local" interchange connection associations as well as link-to-trunk "toll" associations.  Trunk traffic is aggregated in large bit blocks per channel for communication efficiency (high ratio of traffic to link control information).

Abstract: "MULTIPLEX INTERROGATION SYSTEM USING PULSES"                 ABSTRACT OF THE DISCLOSURE               This interrogation system monitors the status of a plurality of protection zone transducers by repeatedly supplying a series of sequential interrogation pulses thereto sufficient to address and scan every transducer associated with a protection zone.  Reply pulses are received from a trans-ponder associated with a protection zone transducer and the reply pulses received over a selected number of prior sequential scans form a response pattern from which the condi-tion of each transducer and its protection zone is determined.          At least three conditions may be determined from the reply response pattern, including an alarm condition, a normal condition, and an out-of-service condition.  Information relative to each transducer and its respective protection zone is stored in the form of bits at memory addresses cor-responding to the count of the protection zone transducer from which that information is received.  Provision is made for synchronizing the transducers associated with the respective protection zones to the count of interrogation pulses delivered thereto to thereby maintain accurate correlation and integrity between the protection zones addressed and the reply pulses received.  The interrogation and reply pulses are preferably direct voltage pulses and the system is compatible for use with connection to a standard telephone line system.          Information in the form of a visual indication and printed record may be provided relative to the status, function and number of a selected transponder and the condition of its protection zone.

Abstract: ABSTRACT:         The invention relates to a magnetic domain memory.          The domains are driven along a structure of discrete elements by a rotary magnetic field. The structure comprises at least two domain detection elements which are formed by inter-connected chevrons. The detection signal is based on the magnetoresistive effect of the series of chevrons.          The domain detection elements are pair-wise connected to relevant inputs of one or more pick-up elements which act as a difference determining unit. The detection elements of a pair are arranged to be rotated 180° relative to each other in the plane of the plate, and are otherwise identical.          The detection elements are generally asymmetrical in that a majority of pairs of successive chevron elements are interconnected in positions situated between their centre and each time a similar end.Thus, upon passage of a domain within a period of the rotary magnetic field, each time a comparatively large and a comparatively small domain signal can be generated. A domain can then be applied to the detection element in each period of the rotary magnetic field, without mutual interference of the detection signals of directly successive domains. This is also possible for the other detection element of the pair while the detection signals are applied to a difference determining unit.          Thus, detection with interference compensation is achieved.          The information density is high, while the bit frequency may amount to 2 bits per rotary field period per pick-up element used.

Abstract: ABSTRACT OF THE DISCLOSURE       An antibody-specific solid phase immunoadsorbent is prepared by adsorptivety binding a lipid-containing viral antigen, such as hepatitis B surface antigen, to the surface of a porous glass carrier having an average pore diameter within the range of about 40-200 nm and an adsorptive surface which within the pH range of 2-8 is capable of selectively and stably binding lipid-containing materials, employing an adsorptive buffer having a pH within such range.  The high adsorptive selectivity of the carrier surface for the antigen under such conditions, enables preparation of the immunoadsorbent directly from whole human plasma containing the antigen, without the necessity for prior antigen purification.  The resultant immunoadsor-bent has a high complexing specificity, efficiency and capacity for the specific antibody to the bound antigen, is capable of providing reasonably high yield of the specific antibody, and is stable under the conditions re-quired for antibody-antigen complexing and dissociation, thereby rendering it highly effective for the isolation and purification of the specific antibody by affinity chroma-tography techniques.         A specific application of the methods and materials described which is of particular clinical significance is in providing a relatively simple and inexpensive pro-cedure for recovering purified hepatitis B antibody from standard immune serum globulin.
