Title: Blow molding process and product
Inventor: SADR CHANGIZE
IPC: B29C49/00
Filed: 1989-12-06
Granted: 2000-10-31
Abstract: Blow molded multi-layered articles for automotive use, for example ducts, hoses, tubes, sealing devices and covers commonly include two layers of compatible material, both layers being formed of expensive, highly resistant materials. It has been found that the outer layer of a two-layered article or the middle (and possibly outer) layer of a three-layered article can be produced using a relatively inexpensive, non-resistant material without sacrificing flexiblity or other desirable physical properties of the finished product. For example, the inner and outer layers of a three-layered article can be formed of a thermoplastic rubber, which exhibits the elastomeric performance of vulcanized rubbers and the processing simplicity of thermoplastic polymers, and the middle layer can be formed of a polypropylene based thermoplastic elastomer.

Title: Geothermal well chemical injection system
Inventor: GODARE WILLIAM L
IPC: E21B33/068
Filed: 1990-07-27
Granted: 1997-03-11
Abstract: A system for injecting chemicals into a geothermal well near the bottom of the well bore for optimum efficiency. The system includes a spool assembly with a master valve for control of the geothermal-flow and a secondary outlet formed of an angle to permit the chemical injection chamber to be lowered into the well.  The secondary outlet is attached to the main spool in such a way as to allow internal thermal expansion while permitting the chemical injection chamber to be fed by capillary tube to the bottom of the well bore. The chemical injection device includes an injection chamber through which the chemical  is disbursed and a  segmented sinker bar to provide the necessary weight to carry the chamber to the bottom of the well against the geothermal well flow.  An annular seal assembly in the spool prevents leaking  by  being  pressure  energized  by  the  geothermal production  fluid.   As  a  result,  production  can  continue during the chemical injection process.

Title: Method and apparatus for improved job stream printing in an electronic printer
Inventor: ORTIZ PEDRO R
IPC: G03G21/00
Filed: 1991-08-08
Granted: 1996-09-24
Abstract: Productivity in electronic printer incorporating finishing activities and operating in a job streaming mode is enhanced by utilizing software to calculate and predict the minimum delay (measured in skip pitches) in successive jobs requiring finishing activities such as binding and stapling. Printing and collating of sets of original scanned documents are controlled so that collated sets are successively presented by the printer to the finishing means nearly coincident with conclusion of the finishing activity being accomplished for a current job. Additional software innovations allow job scheduling for jobs involving complex pitch time delays created by scanning simplex and duplex documents returned in random order. For this case optimum delay time is the cumulative finishing hardware delays as well as imaging/paper path delays. Still another feature is a predictive algorithym which is used to increase reliability of printer components by cycling down the printer between jobs in situations where the finishing activity for a current job requires an extraordinarily long time to complete compared with the cycle down/cycle up time of the printer.
