Title: Multi-level fiber-optic liquid-level sensing system
Inventor: NEMETH FRANK A
IPC: G01F23/28
Filed: 1990-09-25
Abstract: F.9033 MULTI-LEVEL FIBER-OPTIC LIQUID-LEVEL         SENSING SYSTEM                  ABSTRACT OF THE DISCLOSURE      Plural sensor prisms and associated optical-fiber circuits are arrayed as a single vertical stem by which the individual prisms serve for response to each of a plurality of different liquid levels.  Each prism is formed of light-transmitting plastic material which can be injection-molded to precision dimensions. The body configuration is such as to adapt to arrayed interconnection with tubular members, also of plastic, and bonded at telescoping fit of each prism to the tubular member or members to which it is connected. The prism configuration relied upon for sensed response to the presence of immersing liquid (as compared to air) is a solid region having an exterior profile which includes a downwardly convergent conical surface portion at least at spaced locales which are at equal but opposite offset from the cylindrical body axis, wherein the geo-metric apex angle of downward convergence is 90 degrees. As long as a given prism is exposed to air, a large amount of light is transmitted (by reflection within the prism) from a transmission optical fiber to a receiving optical fiber.  But when immersed in a liquid, a portion of the light from the transmitting fiber is refracted into the liquid, resulting in a clearly detectable decrease in the amount of light coupled to the receiving fiber.
Patent CA-2026740-A1 (CA)
Inventor: TAYEFEH MOROVAT
IPC: G11B19/02
Filed: 1990-10-02
Abstract: A magnetooptic storage member is scanned by a single laser beam.  The beam intensity is sufficient to heat a localized area of the storage member to be above the Curie temperature for enabling reversing the remanent magnetization of the localized  area.   Such  localized  area  is  subjected  to  a magnetic bias  field for directing which of the  remanent directions  shall be  assumed in the  localized area.   The storage member and laser beam are relatively moved such that a front or leading portion of the localized area does not reach the Curie temperature.  The light reflected from this leading portion, which moves with the laser beam relative to the storage member, is detected for indicating the initial remanent state of the localized area before any changes are made by the combination of the bias field and the laser beam.

IPC: H04M1/02
Filed: 1990-02-21
Abstract: A cordless loud-speaking telephone of the present invention is shaped to be placed on a table or desk or to be suspended from a ceiling.   Unlike cordless portable telephones of the handy transceiver type, it enables hands-free talking or communication through a receiving speaker and a transmitting microphone located outside a casing.   An antenna conductor and counterpoises are projected from the casing, and a microphone is attached to the counterpoises or the antenna conductor  such that the microphone  is separated as remotely as possible from the speaker in the casing.   As a result, howling and echo which disturb talking or communication via the telephone can be suppressed.  Further, plural microphones are attached to plural antenna conductors or counterpoises to cancel the sound of the receiving speaker to prevent the voice from again entering the microphones, or the microphones are attached to the counterpoises or the antenna conductors in such a manner that they effectively receive the voice from the mouth of a talking person from a certain direction.  This enables hands-free talking or communication to be more effectively and reliably achieved.

Inventor: HOHN ANDREAS
IPC: C07H15/12
Filed: 1990-08-29
Abstract: The present invention relates to neurotrophin-3(NT-3), a newly discovered member of the BDNF gene family.      It is based, in part, on the identification of regions of nucleic acid sequence homology shared by BDNF and NGF.     According to the present invention, these regions of homology may be used to identify new members of the BDNF/NGF gene family; such methodology was used to identify NT-3. The present invention provides for the genes and gene products of new BDNF/NGF related neurotrophic factors identified by these methods. According to the invention, NT-3 may be used in the diagnosis and/or treatment of neurologic disorders, including, but not limited to, Alzheimer's disease and Parkinson's disease. Because NT-3 has been observed to exhibit a spectrum of activity different from the specificities of BDNF or NGF, NT-3 provides new and valuable options for enduring regrowth and repair in the central nervous system.

Abstract: ABSTRACT OF THE DISCLOSURE     An automatic choke apparatus is provided having a choke plate mounted for variable rotation in a carburetor between a closed position and an open position wherein a flow of air entering the carburetor is substantially obstructed in the closed position compared to the open position whereby the flow of fuel entering the engine is increased when in the closed position.  The choke plate has a choke shaft arm for rotatably moving the choke plate.  The automatic choke apparatus has a throttle plate downstream from the choke plate mounted for variable rotation in the carburetor between an open position wherein a flow of air and fuel mixture exiting the carburetor is at a maximum and a closed position wherein the flow of air and fuel mixture exiting the carburetor is at a minimum.  The throttle plate has a throttle lever for rotatably moving the throttle plate.  The throttle lever is engagable with the choke shaft arm as the throttle plate is rotated toward the closed position to rotatably move the choke plate toward the open position.  The automatic choke apparatus includes engine speed governing structure for moving the throttle plate to limit the maximum speed of the engine.  The engine speed governing structure urges the throttle plate toward the closed position after the engine is started such that the throttle lever engages the choke shaft arm to move the choke plate toward the open position.
