Patent CH-519804-A (CH)
Title: Carbon dioxide laser - using gas discharge pumping at ambient pressure for cheapness at low powers
Inventor: JACQUES BEAULIEU A
IPC: H01S3/038
Filed: 1969-11-28
Abstract: A long tubular envelope has at one end an optical resonator, at the other end a gas escape combined with window for the laser beam, a feed part for the carbon dioxide and on each side of the optical axis a set of electrodes, one being esp. a continuous bar and the other set a number of spikes each connected independently via a resistor to one side of the high voltage source, the bar being connected to the other side. The electron flow in the discharge across the optical axis is controlled to a value e.g. 0.2-1.0 eV. Elimination of vacuum pump, sealed windows etc. leads to very large cost reduction and this follows the use of a pump discharge at atmos. pressure or above.

IPC: G06F9/44
Filed: 2000-11-30
Abstract: A fax machine (8) includes a print controller (30), a fax controller (14) and random access memory (44). Generic control code (54) is stored in ROM (42) of the print controller (30), and paper path code is stored in ROM (26) of the fax controller (14). Upon startup of the fax machine (8), the fax controller (14) passes copies of paper path code functions (50) and variable values (52) to the print controller (30) which writes the variable values (52) to a jump table in the random access memory (44), writes the functions (50) to designated portions of the random access memory (44), and writes starting addresses of the functions (50) to the jump table. During operation of the fax machine (8), the print controller (30) executes the generic control code (54) and uses the jump table to access the variable values and to execute the functions. Thus, the jump table allows the print controller (30) to interface the generic control code (54) with the device-specific variable values (52) and the functions (50). Another embodiment has a computer in place of the fax engine (10).

Title: Method and apparatus for producing a laminar air flow through a print zone of an ink-jet printer
Inventor: WOTTON GEOFF
IPC: B41J11/00
Filed: 2001-01-03
Abstract: A cross-flow fan 301 provides a laminar flow 203 of air across the print surface of a media sheet 205 during printing thereof as the sheet passes through a print zone PZ. The airflow scrubs the boundary layer of the print surface such that paper cockle is reduced by a resultant improvement in drying time. The sheet may be conductively heated by a halogen lamp 327 as it is fed through the print zone such as to evaporate the carrier in the ink. The direction of air flow 203 may be reversed from an upstream "positive" flow direction (Fig.3) to a downstream "negative" flow direction (Fig.4) such that the air flow is in the opposite direction to the sheet transport direction 211. A deflector (Fig.5) may be provided on a print head carriage (109,Fig.5) to redirect the air flow, as shown by arrows 503, away from the print zone, and shield the zone during deposition of drops. The deflector prevents interference with ink droplet flight trajectories due to the positive airflow through the print zone. The air flow immediately returns across the print surface after the drops have been deposited.

Title: Navigation satellite system
Inventor: DARBY BARRY JAMES
IPC: G01S1/04
Filed: 2001-10-04
Abstract: To remove the requirement for accurate atomic clocks in navigation satellite systems, such as Global Positioning System (GPS, GLONASS and GALILEO), ground stations 14 transmit timing signals via a communications uplink 16 to a plurality of medium earth orbit navigation satellites 2 via communication satellites 18 in either a medium earth, or geostationary orbit. This enables the navigation satellites to use simpler clocks such as a crystal oscillator. Long term drift of these clocks is compensated by the timing pulses transmitted via the communications satellite. The navigation satellites 2 transmit the timing signals 10 to a ground based monitoring and control station 8 to carry out any corrections, these corrections 12 are passed to the ground station 14 to complete a feedback loop of the corrected timing signals.
