Title: Asymmetric arc chamber for a discharge lamp
Inventor: GILLIARD RICHARD P
IPC: H01J61/02
Filed: 1986-11-14
Granted: 1992-05-19
Abstract: ASYMMETRIC ARC CHAMBER FOR A DISCHARGE LAMP                ABSTRACT OF THE DISCLOSURE A metal halide discharge lamp includes an asymmetric arc tube design which allows a more uniform heating of the arc tube top and bottom wall regions, so that metal halide condensate is distributed over the interior surface of the arc tube in the arc region between the lamp electrodes.  This provides a higher density of metal halide constituents in the arc tube so that a generally more efficacious and lower color temperature lamp can be achieved.  The presence of halide condensate distributed on the arc tube surface also promotes better lumen maintenance by retarding tungsten transport to the arc tube wall.

Abstract: INTEGRATED PROCESS AND APPARATUS FOR THE PRIMARY AND SECONDARY CATALYTIC STEAM      REFORMING OF HYDROCARBONS              Abstract of the Disclosure Integrated primary-secondary reforming operations are carried out with the partly reformed product effluent from the reformer tubes of the primary reforming zone passing to a catalyst-free reaction space at the feed end of a catalyst bed in the secondary reforming zone.  The exothermic heat of reaction generated in said reaction space supplies the necessary heat for the endothermic reforming reaction that occurs in the catalyst bed of the secondary reforming zone, and the still hot secondary product effluent leaving the secondary reforming zone is passed in the shell side of the primary reformer zone to supply the endothermic heat of reaction required in said primary reforming zone.  Essentially autothermal operating conditions are thereby achieved so as to essentially eliminate the necessity for employing an external fuel-fired primary reformer and/or for consuming a portion of the hydrocarbon feed material for fuel purposes.

Title: Elastomeric seal for removable bottom founded structure
Inventor: WATT BRIAN J
IPC: E02B3/16
Filed: 1987-03-12
Granted: 1991-01-29
Abstract: ABSTRACT OF THE DISCLOSURE         The Removable Bottom Founded Structure (RBFS) is an offshore platform for petroleum drilling and producing operations intended for deployment in waters with severe weather and iceberg conditions.  The structure is normally held down by gravity, but during the deballasting procedure a hold-down system is employed to keep the platform on the subbase until site evacuation.  The system that is used to hold the platform down onto the subbase is located where the platform meets the subbase.  It operates on the principle of hydrostatics.  On the underside of the columns there are elastomeric seals that define chambers between the column and the subbase which may be evacuated by pumping.  Pressure by the platform weight forces the elastomeric seals down onto the subbase to create a fluid-tight seal so that no seawater will enter the evacuated chambers.  The reduction of the buoyancy forces will hold the platform onto the subbase until such time as the platform is totally deballasted.  Once that has occurred, the hydrostatic hold-down system is disengaged and the platform will quickly rise to the surface.

Title: Draped parison blow molding
Inventor: LEGGE RICHARD C
IPC: B29C49/48
Filed: 1987-04-30
Granted: 1992-04-28
Abstract: Abstract:          A double-walled plastic box is molded from a single parison in an unlimited depth by closing the bottom of parison and draping it downwardly over a core so that a leading part of the parison forms an inside wall of the box and a following part of the parison forms an outside wall of the box.  After parison is draped over core, outer mold parts close around the core and the draped parison; and the box is blown in a cavity between the core and the outer mold parts.  The parison can be ballooned while draping down over the core to enlarge the parison to stand out from and surround the core, which can be raised during the draping process.  Parison can also be deballooned after draping to stay within the confines of outer mold parts while the core raises and while the outer mold parts close.

Abstract: BROADCASTING MESSAGES IN A DISTRIBUTED PROCESSING SYSTEM            Abstract A method and apparatus for transmitting messages from one processor to a plurality of other processors in a distributed processing system having no hardware message broadcast facilities. The transmitting processor includes a broadcast program process for controlling the transmission of any messages destined for a plurality of other processors. Different client processes in the transmitting processor request the broadcast process to transmit a broadcast message. The single broadcast process controls the number of individual messages which are sent out sequentially to each of the receiving processors in such a way as to ensure that the broadcast messages do not interfere with other message traffic that frequently has tighter delivery time requirements. The broadcast process transmits the broadcast messages to each of the plurality of recipient processors without waiting for acknowledgment response messages from any of these processors. The broadcast process collects received acknowledgment response messages and informs the client process of the summarized response results.

Abstract: AN AIRBORNE ANTENNA AND A SYSTEM FOR MECHANICALLY STEERING AN AIRBORNE ANTENNA            ABSTRACT OF THE DISCLOSURE   A helical-element antenna as part of a communication system is mechanically steered with reference to an azimuth axis and an elevation axis within a positioning envelope greater than hemispherical.   The  system  for  mechanically  steering  the helical antenna  includes a supporting frame having an azimuth member with a  longitudinal  axis  coinciding with the azimuth axis around which the antenna rotates.  Further, the supporting frame includes an elevation member that is integral with the azimuth member and has a longitudinal axis displaced from the azimuth  axis.   An  interface  fitting  rotatably  mounts  the antenna  to  the  elevation  member.   The  supporting  frame  is rotatably  mounted  to  a  pedestal  base  that  has  a  plane perpendicular  to  the  azimuth  axis.   To  position the antenna about the azimuth axis,  an azimuth steering unit is energized to rotate the supporting frame 360 degrees around the azimuth axis. For positioning the antenna about the elevation axis, an elevation steering unit rotates the interface fitting and the antenna through a gear coupling about the elevation axis.  The total rotation excursion about the elevation axis is typically 180 degrees and points the antenna through a range of elevation angles.     7 9 2 9 f

Granted: 1992-02-11
Abstract: ABSTRACT           A prefilled syringe for one or two component medicaments is based upon the use of a vial containing a medicament or one component of a medicament,  the vial having an open bottom closed by a piston.  When the piston is coupled with a plunger, and an adapter cap having an internal needle and an external connection for a needle is placed over a cap of the vial, the latter is converted into a prefilled syringe.  The piston has an axial passage closed by a resealable septum, so that a separate diluent stored in a flexible capsule may be introduced into the vial through the piston by a double ended needle mounted on a further cap applied to the capsule, the further cap being coupled within the tubular interior of the plunger so that the double ended needle penetrates the septum in the piston.  The capsule is pushed forward onto the double ended needle when its contents are to be expelled into the vial.   The capsule  and its cap are then removed and discarded.
