Abstract: Abstract of the Disclosure:       In a token passing slotted loop network comprising a master station and a plurality of slave stations, a plurality of slots circulating through the loop and each of the slots having a fixed length and comprising a header portion and a data carrier portion, a particular one of the stations having the token transmitting its own data signal by use of one or more of the slots, the particular station transmits an end mark in the header of a particular one of the slots at an end of transmission of the own data signal and strips incoming slots from a start of the transmission of the own data signal until reception of the end mark circulated through the loop.  The particular station frees the token by inserting the token in the header of the particular slot.  The token can be inserted in the header of one of the slots after completion of the transmission.  Each of the slave stations writes into a priority request section in the header of each slot a particular priority request representative of a priority level of the own data signal when the own data signal occurs thereat.  The master station writes the highest one of the priority request into a priority section in the header of each-slot.  Each slave station detects the priority in the priority section and starts to acquire the token when the detected priority is lower than the particular priority request.

The upper end of one side edge of each side panel is pivoted to the jamb of a doorway, while the upper end of the opposite side edge of each side panel is pivoted to the adjacent side edge of a center panel.  A track is located above the doorway and a pair of trolleys are mounted or movement on the track.  Each trolley includes a vertical pivot shaft which is connected to a center panel at a location midway of the width ofthe panel.  A drive mechanism is mounted in the header and includes an endless cable which is connected through a torque arm to the shaft of each trolley.  Operation of a reversible drive mechan-ism in one direction will operate through the cable to move the panels to a closed position where they enclose the doorway, while operation of the drive mechanism in the opposite direction will move the panels to the open or folded position.  Flexible weather strips can be connected between the side edge of each side panel and the door jamb, and similarly flexible weather strips can interconnect the adjacent side edges of the side panels and center panels.  To ensure that the panels fold in the proper manner, resilient shock cords inter-connect the adjacent side edges of the side and center panels.

Title: Method and apparatus for injection molding ceramic valves
Inventor: VAN REATHERFORD LARRY
IPC: B28B7/34
Filed: 1990-12-27
Abstract: Abstract of the Disclosure An apparatus and method for injection molding a unitary ceramic part such as an engine valve contemplates a mold having a die cavity therein shaped like an engine valve.  The die cavity is formed with a head portion of the valve at a first portion of the cavity and a stem portion of the valve at a second portion of the cavity. Molding material is injected slowly into the die cavity by an injection molding apparatus connected to the mold.  As the molding material is slowly injected into the cavity, the material moves up through the die cavity forcing air out of a vented portion on the mold until the die cavity is filled.  A temperature control plate, connected to the mold adjacent the first portion of the die cavity, allows a cooling fluid to circulate therein in order to permit controlled cooling of the part from the head portion of the valve down to the stem portion.  After the valve has cooled and solidified it is removed.

Inventor: CLARISSE OLIVIER B H
IPC: G06F9/44
Filed: 1991-02-07
Abstract: A computer program specification system is disclosed for interactively creating program specifications responsive to user input. The system provides facilities to respond to changes, supplied interactively, to a program specification without recompiling the program specification, and immediately to display a simulation of those changes. The system also supports the merging of actors, which are software objects comprising data structures and program procedures, and the merging of actor behavior. A user of the system creates a program specification by specifying actors for use in a plurality of scenarios, and operational steps of the plurality of scenarios. The system executes operational steps of a scenario to evaluate the consistency of the specification and actor data Execution of an operational step comprises simulating the operational step upon the occurrence of predetermined conditions and storing the results of the simulation. Execution of a sequence of operational steps can be reversed or undone in order to insert a change in the specification prior to resimulating the undone sequence or other related sequences. Simulation of an operational step comprises one or more of: executingcommunications among actors, asserting relationships among actors, executing a logical or arithmetical computation for actors requesting input of a decision choice.

Title: Lipid excipient for nasal delivery and topical application
Inventor: WEINER ALAN L
IPC: A61K47/24
Filed: 1990-02-14
Abstract: ABSTRACT OF THE DISCLOSURE Methods and compositions are described for liquid or gel forms of a lipid excipient to be used in pharmaceutical or cosmetic preparations. The lipid excipient comprises a phospholipid such as a lysophospholipid, for example, mono-oleoyl-phos-phatidylethanolamine ("MOPE"). Relatively low concentrations of the lipid can be employed in forming the gel, e.g., about 1-2%. The invention discloses the use of a lipid delivery system at a relatively low lipid concentration as a non-toxic, non-irritating carrier or excipient alone or in combination with other agents, for both drugs and cosmetics. For example, the lipid excipient in sprayable or dropable form has special utility in the non-irritating delivery of peptides (e.g., calcitonin and insulin) to the nasal mucosa, due to the ability of the excipient to enhance absorption across nasal membranes. As a cosmetic, it can be used alone or in combination with biologically active agents.

Title: Method of start-up of a contaminated hydrocarbon-conversion system using a contaminant-sensitive catalyst
Inventor: FOUTSITZIS ARTHUR A
IPC: C10G35/00
Filed: 1991-07-29
Abstract: A hydrocarbon conversion process that uses a contaminant-sensitive catalyst and a conversion system that has been contaminated through contact with a contaminant-containing prior feed is started up by utilizing a hydrocarbon solvent in the absence of the contaminant-sensitive catalyst to purge contaminants, such as sulfur, from the conversion system. Complementary contaminant-removal steps may include oxidation, reduction, and contaminant removal with a sacrificial particulate bed. This solvent purge avoids deactivation of a subsequently loaded contaminant-sensitive catalyst, such as a reforming catalyst selective for dehydrocyclization.
