Title: Apparatus for storing, mixing, and using medication
Inventor: OGLE GEORGE B II
IPC: A61M39/04
Filed: 1990-10-02
Abstract: APPARATUS FOR STORING, MIXING, AND USING MEDICATION             ABSTRACT OF THE DISCLOSURE     Medication which is stored dry or in a concentrated liquid form, and which must be mixed with a diluent before use,  is stored in a medication container which has an opening  for  transferring medication  to  and  from the container.  A sealing member over the container opening has an elongated passageway extending through it to permit flow of material to and from the container.  A removable closure in the passageway prevents flow of material until the medication is ready for use.  A tapered connector on the sealing member surrounds the passageway, and is adapted to receive a mating tapered connector on another container into which material may be transferred from the container after removing the closure from the passageway.      A medical injector includes a cylindrical vial having an open end and a closed end.  A resilient plug is press-fitted into the open end  of the vial so a liquid diluent can  be stored in a sterile condition in the vial.   An elongated barrel includes a sealing member at one end, and the sealing member has a passageway extending through it.  An elongated cannula is connected at one end to the passageway.  The other end of the cannula terminates in a scarf in the vicinity of the plug.  A threaded fitting on the other end of the barrel receives mating threads on one end of the plug extending toward the barrel.   The vial and cannula are first held in an assembled,  but nonoperating, position when  the threaded barrel is coupled to the plug.  Upon further interlocking of the plug with the barrel, the scarf end of the cannula pierces the plug so liquid in the vial can flow through the cannula and out the passageway in the sealing member.   A tapered connector on the sealing member and around the passageway is adapted to receive a mating tapered connector on the medication container so that material can be transferred back and forth between the vial interior and the container by reciprocating the plug in the vial.

Title: Integrated process for the production of diisopropyl ether and gasoline
Inventor: OWEN HARTLEY
IPC: C07C2/00
Filed: 1990-10-04
Abstract: ABSTRACT           A process is disclosed for integrating etherification to produce diisopropyl ether (DIPE) with processes to convert oxygenates and hydrocarbons to gasoline boiling range hydrocarbons in a manner which eliminates the requirement to recycle unreacted C3 hydrocarbons to the DIPE etherification zone.  In the novel integrated process the unreacted C3 hydrocarbons are separated as vapor and passed to a conversion zone in contact with acidic metallosilicate catalyst.  Depending on the conversion conditions the unreacted C3 hydrocarbons are converted to gasoline, distillate and/or aromatics, preferably in conjunction with additional feedstock containing lower oxygenates, olefins or paraffins.  Also, isopropanol (IPA) and minor by-product dimers and trimers of propene from the DIPE reaction are separated and passed as a feedstream to the oxygenates and hydrocarbon conversion zone.  In one embodiment, the water feedstream for the DIPE reactor is first passed to the DIPE effluent high pressure separator where it serves to extract a portion of the IPA in the effluent stream.  The aqueous effluent from the high pressure separator is then introduced into the etherification zone for hydration of propene and etherification to form DIPE.

Title: Method and apparatus for detecting a transmitted control code for initiating a latching loopback test procedure
Inventor: FAIN MARC
IPC: H04M3/24
Filed: 1991-02-20
Abstract: In a data port for a digital data system in which latching loopback is implemented, a unique and efficient algorithm is utilized to achieve M out of N control byte recognition.  In the algorithm, N-M+1 variable length windows are used to count identified control bytes.  The algorithm opens a window when the desired byte has been detected, counts the identified bytes while the window is open, and closes the window when a non-target byte is detected.  The counts in the various windows are summed to determine if M bytes have been detected.  A window having the oldest byte count is effectively dropped so that the window is available to count newly-arriving target bytes.
