Abstract: LASER DC BIAS CONTROLLER ABSTRACT OF THE INVENTION A laser DC bias controller is disclosed for controlling and monitoring the laser of a fiber-optic transmitter.  The arrangement comprises an optical power monitor including a light detector for converting the light output by the laser into photo current.  The photo current is converted by the optical power monitor into a voltage representation of the magnitude of the light output by the laser.  The voltage representation is output to a DC constant current source which uses the voltage to provide operating current to the laser of sufficient magnitude to keep the laser operating at a set output level.  A transmit data detector monitors the incoming data signals to the fiber optic transmitter and outputs to the optical power monitor a current signal which indicates a failure of the data signal.  The optical power monitor converts the current signal to a voltage representation which is output to the DC constant current source.  The DC constant current source subsequently turns off the operating current to the laser and an alarm signal representing a failure of the data drive circuit is output to a controller interface.  Finally, an optical output detector connected to the optical power monitor is provided to compare the voltage output by the optical power monitor to a set value.  When the voltage falls below the set value, the optical output detector sends an alarm signal to the controller interface indicating that the laser has failed.

IPC: B02C23/32
Filed: 1989-01-23
Granted: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for pulverizing a material such as sand to a desired particle size.  The apparatus has a pulverizing shell in which the material to be pulverized is fed and pulverized.  The pulverized fluid-carried material overflows the shell so as to be fed into a settling classifier, where the coarser material settles and is discharged through its bottom opening back into the shell for repulverization.  The finer material overflows the classifier and is fed to an intermediate bin, which has its bottom connected to the shell through a valve.  When the bin is filled up with the material, the valve is opened so that the material in the bin is returned to the shell.  The material is thus circulated through the shell, classifier and intermediate bin.  The shell is adapted to be alternately connected to the intermediate bin and a product collector bin by a changeover valve.  When the material overflowing the shell is pulverized to a desired particle, size, the shell is now brought into communication with the collector bin.

Abstract: ABSTRACT        Control apparatus for a line operated telephone is described.  This control circuitry is designed to be primarily telephone line powered and to not employ a large capacitor for storing power to sustain the circuitry during open switch intervals in which the telephone line is not powered.  Rather, the present circuitry includes a telephone line monitoring circuit for sensing a power down condition, a processing means such as a microprocessor with an associated power down program for storing process status at a time just prior to power down and for resetting the processing at the appropriate place upon power up, and low power state monitoring latches for monitoring important events, such as an on hook condition, coin collection and refund operations occurring during an open switch interval.  In combination, a low power operation is achieved primarily utilizing a regularly interrupted source, the phone lines, and requiring only a small battery to power the low power monitoring state monitoring latches.

Abstract: This invention relates to novel methods for converting a diastereomeric mixture of S-protected derivatives of an orally active inhibitor of an angiotensin-converting enzyme (ACE) and its analogues into its separate optically resolved diastereomeric components. Specifically the invention relates to methods for the preparation of optically purified captopril for the preparation of optically purified captopril and its analogs from racemic precursors.  This resolution process is achieved through the fractional crystallization of S-protected derivatives of captopril and its precursors, which derivatives are useful for the reason that they are (1) easily prepared from novel precursors, (2) resolvable to their optically purified stereoisomeric species and (3) convertible to non-derivatized stereoisomeric species which correspond to the pharmacologically active inhibitor and its analogues.  The invention also pertains to the aforesaid novel derivatives utilized in the resolution methods and their precursors.  In addition, novel methods for preparing the derivatives and their precursors are also noted herein.

Abstract: SPRINKLER SYSTEM AND SPRINKLER ASSEMBLY     ABSTRACT     A fire  suppression  system  for  use with ducts carrying corrosive gases has a multiplicity of sprinkler assemblies, each having an easily replaceable adapter with a sprinkler head having a fusible alloy fill.  The head is screwed into one end of the adapter which has an integral flange at its opposite end.  The adapter is inserted in a flanged nozzle which is part of the duct.  The adapter flange is bolted to the nozzle flange which has a central opening adapted for connection  to  a  source  of  extinguishing  fluid.   A continuous  passage  for  fluid  is  provided  through  the adapter and the flanges together with a passage through the sprinkler head, the latter being opened when the system is activated.   Only the face of  the adapter  and a small protruding portion of the sprinkler head are exposed to the corrosive   gases.    The   sprinkler   head   has   a corrosion-resistant  body and  has  a central  passage containing a seal plug and a fusible fill at opposite ends and  a piston  between  the  fill  and  the  plug.    Upon activation,  the fill melts,  and fluid pressure cleanly ejects  both  piston  and  plug  from  the  passage  in  the sprinkler head, thereby providing full bore for the passage of fluid.  The piston insulates the fusible fill from any cooling effect, and provides reliable operation with short response times.
