Title: Method and system for drop marking and a drop deflector for use therewith
Inventor: ARWAY GEORGE
IPC: B41J2/09
Filed: 1993-10-11
Abstract: Deflection electrodes (90, 92) create a region of high electric field intensity and an ink mist neutralization region (96). High field intensity is achieved by spacing the deflection electrodes (90, 92) closer together than has hitherto been possible. The higher deflection field intensity facilitates full ink drop deflection and character size although the effective length of the electrodes (90, 92) may be substantially less than those in conventional ink jet printing heads. Insulative material (94) is placed over the high vol-tage deflection electrode to obviate high voltage arcing. The insulated electrode and the ink drops to be deflected may be of the same polarity permitting an ink mist neutralization region (96) to be located on the low voltage electrode (90).

Title: Process and a composition for making cellulosic composites
Inventor: FERRETTI ARTHUR
IPC: C08H99/00
Filed: 1995-05-30
Abstract: The  specification  discloses  an  unorthodox  system  for manufacturing strong, light-weight and weather-resistant cellulosic composite materials from discarded paper and newsprint, and paper-mill sludge - and from an unlimited variety of particulated fibrous lignocellulosics - without the use of an extrinsic adhesive.  Both the matrix-forming resin and the fiber-substrate, which comprise the entire composite, are spontaneously created in situ at ambient conditions by the ammoniation of a mixture of a protein-containing material and a particulated cellulosic.  Heating an article shaped from such a mixture to above 175°C polymerizes the resin and bonds the fiber-substrate into a cellulosic composite product.   Also disclosed is a process for manufacturing reinforced and laminated composites as well as a composition which simplifies the production of both cellulosic composites and all-biomass thermosetting resins.

Patent CA-2158925-A1 (CA)
Title: Scalable and stable, cw photolytic atomic iodine laser
Inventor: SCHLIE LA VERNE A
IPC: H01S3/223
Filed: 1993-03-22
Abstract: The present invention is a scalable and stable, cw photolyti-cally excited atomic iodine laser (10) operating at 1.315 microns. An initial power level of 55 watts/liter was obtained via the cw photolysis of an alkyl-iodide gas (20) like C3F7I. The greatly en-hanced laser performance was achieved using a microwave (16) excited, electrodeless Hg plasma lamp (18) excited with a d.c., low ripple (1%) cw microwave radiation. Both high flow, air cooling and above ambient temperature (50 - 150 °C) liquid, dimethyl polysiloxane cooling of these high pressure Hg lamps (atmospheres) provided long lifetime operation with the latter promoting stable laser operation. Transverse flow for the remo-val of the quenching by-product I2 is incorporated into the laser (10). To insure good laser amplitude stability, both the high power magnetrons (operated at 1.5 KW but capable of 3 KW performance) and the lamp (18) (normally Hg) are liquid cooled, respectively  by H2O and dimethyl polysiloxane. The use of the high ultraviolet transmissve properties of the dime-thyl polysiloxane lamp coolant removed the requirement for large flow air cooling (150 cfm) of the lamps (18); thereby, allowing good amplitude stability. Elimination of air coolant en-abled use of a slow N2 purge; thereby preventing  the formation of ozone, 03, a strong absorber of the UV radiation exciting this cw photolytic atomic iodine laser (10). The scalable, prolonged and stable operation of this cw photolytic iodine laser system (10) is possible via use of closed cycle, condensative/evaporative fuel system coupled to a high flow (10 meters/sec), internal blower for heavy gases (20) like the alkyl iodide C3F7I. Over an excitation length of 25 cm, an average small signal gain coefficient of 2 %/cm is produced by exciting the transvesely flowing C3F7I from one side. High powers are achievable by exciting the gas (20) from both sides, increasing the ultraviolet lamp radiation with higher microwave power and/or more efficient UV operating plasma lamps (18), and/or "tailoring" the UV lamp emission into the C3F7I absorption in the 240-320 nm region. Enhanced efficiencies (I to 6 %) are possible by optimizing all components associated with the d.c. mic-rowave excited lamps (18).
