  • Patent number: 5427768
    Abstract: This invention involves methods and compositions for preparation of unstable carbonated calcium phosphate solutions, which are supersaturated with respect to calcium phosphate solids and carbon dioxide and the use of such solutions for the treatment of dental tissue and hyposalivation. Specifically the methods include mixing a stable alkaline carbonated solution containing carbonate with a stable acidic calcium solution, either or both solutions also containing phosphate to create an unstable carbonated solution with respect to calcium phosphate and carbon dioxide. Also, the methods include adding aqueous solution to the solids containing calcium salts, phosphate salts and carbonate salts to create an unstable carbonated solution supersaturated with respect to calcium phosphate solids and carbon dioxide. The methods further include using alkaline solutions to remove the acidic residue from dental tissue and maintain cariostatic conditions.

  • Patent number: 5423776
    Abstract: Coupling for connecting an implantable port catheter to flexible catheter tubes of varying size and diameter. A rigid tapered tube extends from a port opening in the catheter system housing and the catheter tube slides onto the end of the rigid tube. A clamping sleeve having a bore larger than the outer diameter of the tube has a circular gripping shoulder which bites into the flexible tube as the tube and sleeve are pushed onto the tapered surface of the rigid tube extending from the port opening to clamp the flexible catheter tube firmly between the shoulder and the tapered surface. The distance between the gripping shoulder and the tapered tube is variable to accommodate the size of the flexible catheter tube.

  • Patent number: 5424872
    Abstract: Apparatus and methods for stabilizing a line of sight of an optical system without the use of gimbals. The apparatus includes a fixed plano-concave lens element mounted in a frame and a moveable plano-convex lens element mounted in a carriage. The frame mounts onto a preexisting optical system such that the lens elements are nominally aligned with the line of sight of the preexisting optical system. A motor driving unit is provided in the frame which moves the plano-convex lens element back and forth relative to the fixed plano-concave lens element about two orthogonal movement axes in response to small amplitude disturbances imparted to the optical system. The line of sight stabilization apparatus is suitable for retrofit installation onto preexisting optical systems, and in particular, to missile tracking guidance and sighting systems which were originally manufactured or installed without line of sight stabilization capability.

  • Patent number: 5422950
    Abstract: An automatic loss compensation for use in a two to four wire hybrid converter in a telephone system. Many hybrid converters provide a substantially fixed gain for receive signals that are provided to the customer loop telephone line and for transmit signals that are provided to the digital carrier transmission line. The compensation circuit includes a measurement circuit, controller, and receive and transmit amplifier. The measurement circuit determines the length of the customer loop telephone line and provides a length signal. The controller receives the length signal and categorizes the length as being within one of a plurality of segments. The controller appropriately varies the amplification and phase of the receive signal, which is then combined with an inverted transmit signal, in order to substantially reduce reflected signals from the transmission line and transmission line termination.

  • Patent number: 5422564
    Abstract: This invention permits one to trace more than one electrical conductor, each of the electrical conductors being associated with both a circuit breaker and an electrical outlet. The invention consists of a receiver and multiple transmitters. Further, in a single transmitter form of the invention, the invention permits the transmitter to continually transmit its signature signal without power dissipation concerns, just like the ability to continually transmit in the multiple transmitter form of the invention. Lastly, the device is able to trace conductors regardless of the load electrically connected to the conductor.

  • Patent number: 5422916
    Abstract: A partial frame detector provides detection of a frame synchronization pattern in an environment of burst noise that prohibits detection by correlation. A frame synchronization pattern capable of sustaining a minimum of 17 bits clustered in error plus random errors while still providing frame detection is achieved by utilizing a 64 bit Barker derived frame synchronization pattern and an additional process included in a correlation algorithm.

  • Patent number: 5420152
    Abstract: A method for treating circadian rhythm disorders is described. The method involves the administration of melatonin from about 6 hours to about 19 hours prior to when the normal sleep phase should begin, depending on whether a phase advance shift in circadian rhythms or a phase delay shift is desired. This is typically from about 4 hours to about 17 hours prior to the time of endogenous melatonin onset.

  • Patent number: 5417688
    Abstract: Apparatus and methods for detecting the location of transverse holes of an intramedullary nail which has been inserted into a long bone and for aligning a surgical drill to the transverse holes. An insert having a light source at its distal end emitting non-ionizing electromagnetic radiation in the visible spectrum or infrared is inserted into the intramedullary nail, such that the light source is placed adjacent to the transverse holes. The light source may be a directional radiation output emitting the radiation in a direction perpendicular to the axis of the intramedullary nail. The light source may alternatively be an isotropic radiation output emitting radiation in all directions. The surgeon detects the transmitted radiation on the surface of the body of the patient and aligns the drill with the emitted radiation.
