Title: Magnetic recording device and method
Inventor: SOICHI IWAMURA
IPC: H03F3/45
Filed: 1996-06-12
Abstract: Magnetic recording device and method are provided.  The magnetic recording device includes a shaping driver for positive and negative signals whose polarities are reversed, corresponding to the digital information, a push-pull portion for generating a recording current corresponding to the positive and negative signals and generating a transient pulse current during reversal of the polarity of the recording current, and a current switch for switching a current flowing through the push-pull portion in response to the positive and negative signals.   The digital signal is recorded on the magnetic recording medium on the basis of the transient pulse current.  Therefore, without an additional recording equalizer, rise characteristics of a head current is improved and the demand of small-size and low-power is satisfied.  In addition, since the magnetic recording device employs a compensation signal generator for compensating for a variation of the instantaneous value of a recording current caused by use of a rotary transformer, rise characteristics of the recording current during switching the polarity of the recording current can be maintained to be stable.

Title: Call screening method and apparatus for use in completing telephone calls
Inventor: FOLADARE MARK JEFFREY
IPC: H04W84/02
Filed: 1996-07-17
Abstract: A system and method for providing personal communications services are disclosed.  A bridging and signaling unit implements a bridge for connecting telephone calls between a caller, a called party, and an alternate destination.  A caller who calls the personal telephone number associated with a called party is held at the bridging and signaling unit while waiting for a return telephone call from the called party.  The called party is alerted to the existence of the call through a paging system.  If the time period during which the caller is on hold exceeds a time-out period, the caller will be connected to an alternate destination, such as a secretary, an answering service, or a voice messaging system. If the called party places the return telephone call while the caller is connected to the alternate destination, the called party will be connected to the caller and the alternate destination in such a manner that that the called party can hear the conversation between the caller and the alternate destination, but the caller and the alternate destination cannot hear the called party and do not know that the called party has connected, i.e. the called party is on mute mode.  After screening the call, the called party may then indicate that he/she wishes to be connected to the caller, at which time the connection to the alternate destination is terminated and the caller and the called party are connected such that they can speak with each other.  If the called party does not wish to speak to the caller, he/she may hang up, and the connection between the caller and the alternate destination may continue.

Title: Process for metathesis
Inventor: BIGAUSKAS TOMAS D
IPC: C01B11/02
Filed: 1996-10-24
Abstract: A slurry of sodium acid sulfate crystals generally from a chlorine dioxide generating process, is metathesized on no more than one drum filter. The crystals are fed to a first filtration zone on the filter wherein the crystals are separated from the slurry. The crystals are contacted with an aqueous metathesizing medium to effect solid phase conversion of the sodium acid sulfate crystals to neutral sodium sulfate crystals.      The resulting slurry is fed to a second filtration zone on the drum filter element separate from the first filtration zone, wherein the neutral sodium sulfate crystals are separated from the acidic medium formed in the metathesis step. The employment of a single dual service drum filter provides a simplification and cost reduction compared to conventional procedures and to also a minimization or elimination of the impact imposed by the additional evaporative load on the chlorine dioxide generator.

Title: Dynamically controlled routing using dynamic management of intra-link traffic to virtual destination nodes
Inventor: BEDARD FRANCOIS
IPC: H04Q3/00
Filed: 1995-10-26
Abstract: A dynamically controlled routing (DCR) telecommunications network (31A) comprises a plurality of network switching elements (a, b, c, o, t) interconnected by circuit groups (a-b, o-a, o-b, o-c, ...) for carrying calls, and a network processor (25A) communicating with the network elements. At least one of the nodes is a virtual destination node (V) which is a logical entity corresponding to a group of two or more components which are network elements. A link to the virtual destination node need not correspond to a circuit group but is a set of circuit groups connecting to the components of the virtual destination node. Final destinations outside the DCR network can be associated with the virtual destination node as an intermediate destination node, thereby allowing a call to exit the DCR network via any of the components of the virtual destination node rather than via only one Unique Exit Gateway. Where a link to the virtual destination node comprises a plurality of circuit groups, the store of the associated switching element may include proportions for those circuit groups. When attempting to route a call via the link to the virtual destination node, the switching element may attempt the circuit groups in dependence upon the proportions.

Title: Human immunodeficiency virus vaccines and therapeutics containing replication-impaired hiv-1 nef-deletion mutants
Inventor: APTE SATEESH N
IPC: A61P31/12
Filed: 1995-12-26
Abstract: There is currently no specific immunological treatment utilizing live virus for infection by Human Immunodeficiency Virus (HIV) which is a cause of a clinical syndrome called Acquired Immunodeficiency Syndrome (AIDS). Several prior attempts have been made to develop vaccines to boost the humoral immune response to envelope and gag proteins which have been uniformly unsuccessful because of various factors including cell-to-cell propagation of the HIV and its destruction of the cell mediated immune system of the body by its cytopathic and fatal effect on T HELPER (CD4) cells. The present invention describes a method of creating a recombinant HIV virus clone with its nef gene deleted. The invention further describes a method of creating an injectable suspension of the virus particles and preferred treatment protocol for patients infected with the HIV. A protocol for the prevention of wild-type HIV infection has also been described. It is believed that the preferred embodiment works by eliminating blocking of induction of IL-2 mRNA and IFN.gamma. in lymphoid cells by the nef protein, by developing a cell mediated immune response to HIV via cytotoxic T  Lymphocytes (CTL) and by competing with the wild-type HIV for potential hosts and thus increasing the likelihood of exposure of the wild-type HIV to humoral antibodies to gp120, gp4l and gag proteins.
