Abstract: METHOD FOR MAKING SYNTHETIC OLIGONUCLEOTIDES WHICH  BIND SPECIFICALLY TO TARGET SITES ON DUPLEX DNA  MOLECULES, BY FORMING A COLINEAR TRIPLEX, THE SYNTHETIC OLIGONUCLEOTIDES AND METHODS OF USE                          Abstract A method for making synthetic oligonucleotides which bind to target sequences in a duplex DNA forming colinear triplexes by binding to the major groove.  The method includes scanning genomic duplex DNA and identifying nucleotide target sequences of greater than about 20 nucleotides having either about at least 65% purine bases or about at least 65% pyrimidine bases; and synthesizing synthetic oligonucleotides complementary to identified target sequences.  The synthetic oligonucleotides have a G when the complementary location in the DNA duplex has a GC base pair and have a T when he complementary location in the DNA duplex has an AT base pair.  The synthetic oligonucleotides are oriented 5' to 3' and bind parallel or 3' to 5' and bind anti-parallel to the about at least 65% purine strand.          Also described are synthetic oligonucleotides made by the above methods.  The oligonucleotides can be altered by modifying and/or changing the bases, adding linkers and modifying groups to the 5' and/or 3' termini, and changing the backbone.          These synthetic oligonucleotides bind to duplex DNA to form triplexes.  This process alters the functioning of the genes which are bound.  This process can be used to inhibit cell growth, alter protein ratios, treat diseases including cancer and permanently alter the DNA.

Filed: 1990-01-17
Granted: 2000-10-17
Abstract: An apparatus is described for receiving, storing and dispensing elongate flat strip material for use with rotating machinery. The strip material is guided by an inlet guide roller to feed the advancing strip tangentially onto a rotating support member having a series of storage guide rollers which are spaced from each other about a circular path concentric with the machine axis. The strip is wound onto the storage guide rollers to provide a reservoir of strip material arranged in a single row of substantially circular overlapping convolutions concentrically arranged about the machine axis. A sensing arrangement is used to monitor the amount of remaining strip material stored on the rotating support member, and the rotation of the latter is terminated when the stored strip material is about to be depleted, to allow an operator to attach the trailing end of the depleted stored strip with the leading end of a next successive strip material. The arranged storage guide rollers insure a balanced condition of the rotating support member irrespective of the amount of strip material which remains stored.

Filed: 1990-10-17
Granted: 1997-12-30
Abstract: A fiber optic telecommunication system has master site linked to a plurality of subscriber interface sites by a single pair of optical fibers. Downlink messages are transmitted in a continuous TDM format over a first optical fiber from the master site to subscriber interface sites, and in a burst mode TDMA format over a second optical fiber from the subscriber interface sites to the master site.  Each subscriber interface site is coupled to the optical fiber link by way of a multiple fan-out fiber coupling pedestal  at a common location on the fiber pair.  To prevent collisions between successive uplink bursts from the subscriber interface sites, a guard band separates successive uplink messages from one another. The guard band duration accommodates optical fiber transmission distance between the common location on the uplink optical  fiber and the subscriber  interface site whose differential optical fiber transmission distance from the common location is greatest.   A subscriber location has a television decoder associated with the subscriber's television set, through which  television  channel  selection  signals  are  input by the subscriber for transmission from the subscriber interface site to the master site. Power is provided by way of a replaceable battery pack,  housed  in  a  subterrestrial  bell  jar  configuration, effectively insulating the battery pack from extreme temperature changes and the intrusion of moisture.

Abstract: A system for employing a computer to control a device to provide a plurality of services for a plurality of entities. Each entity corresponds to exactly one of the services and each service has its own copy of the code which defines the service. The system associates a process which executes the service with each service. The code for a service defines a finite state machine which is continually executed by the service's process. While in a given state, the finite state machine may traverse a decision graph which is directly accessible to the process. Actions to be taken on traversal of a node of the decision graph may be defined in the finite state machine. The service's process communicates with other processes and with itself by meansof interprocess messages. Each state of the finite state machine contains event handlers for responding to messages received by the service's process. The finite state machine is defined by a special language, the service logic language, and the decision graphs are defined by means of a graphical editor. The compiler for theservice logic language produces not only C++ code defining the finite state machine, but also data base and shell scripts which are used to provision and maintain the services. An embodiment of the system is  disclosed which is used in a service node of a telephone switching network to provide telephone services such as 800 number service, caller ID, and the like.
