Title: Chlorophyll and bacteriochlorophyll derivatives and pharmaceutical compositions containing them
Inventor: SCHERZ AVIGDOR
IPC: A61K47/48
Filed: 1993-07-23
Abstract: Conjugates of chlorophyll (Chl) and bacteriochlorophyll (Bchl) derivatives with amino acids, peptides and proteins are provided by the invention.The amino acid, peptide or protein residue is linked to the 17-propionic acid group of a Chl or Bchl residue directly or through a chain. The conjugates are fox use as photosensitizers in photodynamic therapy and in diagnostics of tumors.

Abstract: A method for re-establishing a communication link that has been lost between a portable unit (406) and a fixed unit or base station (402) provides for a way of quickly re-establishing the lost communication link, on the previously used RF channel by transmitting a link re-establishment code word (900) using MUX 1 or protocol after determining that synchronization has been lost (502) for a predetermined period of time (504). This is followed by automatically switching the portable unit (406) from MUX 1 to MUX 3 communication protocol. Followed by re-establishing communication (re-establish synchronization) between the portable (406) and base station (402) in MUX 3 and switching the two communication devices (402 and 406) back to MUX 1 after the communication link has been re-established. The same steps can be followed by base site (402) if it has been the first to detect loss of the communication link.

Abstract: A machine for making plastic tubing including a plurality of separate carriages for carrying mold blocks about the continuous path. First and second wheel pairs on opposite sides of each carriage ride on first and second tracks respectively through a molding section of the path. An offset wheel is disposed between the wheels of each pair and rides on guide tracks associated with and facing oppositely to the first and second tracks respectively through the molding section. Each mold block is a plurality of sub-blocks secured end to end, with each sub-block having an arcuate face and corrugated with not more than one complete wavelength. Vacuum channels about sub-block end surfaces connect the block face to a vacuum port. Cooling water channels about sub-block end surfaces connect to water inlet and discharge ports for selectively circulating cooling water through the blocks. The mold block ports communicate with respective vacuum, water supply, and water discharge channels in a longitudinal supply tray along which the mold blocks travel through the molding section.  A mold train drive engages a selected number of carriages at the beginning of the mold tunnel to continuously drive the carriages along the mold tunnel. A shuttle drive follows the continuous path through a shuttle area and spaced from the path along a substantial portion of the mold tunnel, and includes first and second carriage engaging sections at substantially opposite points along the drive so that a carriage at the end of the mold tunnel becomes engaged by one shuttle drive engaging section while the other shuttle drive engaging section engages a carriage at the beginning of the mold tunnel. The shuttle drive accelerates when one of the carriage engaging sections enters the shuttle drive portion spaced from the continuous track path to disengage a carriage at the beginning of the mold tunnel, and decelerates to the speed of the mold train drive as an engaged carriage reaches the beginning of the mold tunnel.

Abstract: A dual-duct HVAC system for providing a desired comfort level in a room, includes a controller that carries out a simple operation that determines the total open damper positions for dual dampers in a dual duct system to effect a desired air flow. Using the total open damper position information as damper control  information,  the controller also determines a relative damper position difference required between the two dampers to effect a desired temperature level while also meeting the air flow requirement as determined from the total open damper position information.  The combination of the total open damper position information and the relative damper  position  difference  is  used  as  control information to control both dampers.   Preferably, the controller gives priority of air flow control over temperature control by determining a valid damper  position  difference  range  for  use  in conjunction with the total open damper position information.

Title: Polarization selecting device, light source module and fiber-optic gyroscope
Inventor: NISHIURA YOZO
IPC: G01C19/72
Filed: 1994-07-29
Abstract: ABSTRACT OF THE DISCLOSURE             Small-sized polarizers are required for optical fiber gyroscopes. The fiber-type polarizer or the metal-dielectric multilayer polarizer is small-sized and suitable to conventional gyroscopes. But these polarizers are expensive. A source-sensitive fiber-optic gyroscope is a novel, simplified gyroscope which demands a suitable, simplified, low-cost polarizer.          A birefringent crystal having surfaces inclining at about 45 degrees to the anisotropic axis can spatially separates a beam into an ordinary beam with polarization perpendicular to the anisotropic axis and an extraordinary beam with polarization having a component of the anisotropic axis. A polarization selecting device is produced by-facing ends of two optical fibers to both surfaces of a birefringent crystal. A beam emitted from a fiber is separated into an ordinary beam and an extraordinary beam.          Either of them enters the core of the other beam as a propagating beam. A light source module is produced with a light emitting device, a birefringent crystal and an end of an optical fiber. The birefringent crystal divides a beam from the light source into an extraordinary ray and an ordinary ray. Either of them is introduced into the fiber. Thus the light source module emits linearly-polarized beams.  The light source module is suitable for the source-sensitive fiber-optic gyroscope, because the system dispenses with a polarizer. When a lens has a non-effective peripheral part, the dispersion of beams should be suppressed by interposing a pinhole plate between the lens and the light source.
