Patent CA-2010547-A1 (CA)
Inventor: HINE NATHAN P
IPC: B41J2/19
Filed: 1990-02-21
Abstract: In the representative ink supply system described in the specification, continuous circulation of ink in an ink jet head is accomplished by providing two res-ervoirs connected to each ink jet orifice (11) through corresponding passages (40,15,13,42) so that ink flows continuously from a high-level reservoir past the orifice to a low-level reservoir.  The difference between the levels of ink (45,46) in the reservoirs is maintained relatively constant by inertial pumping during reciprocal motion of the ink jet head or by pressure transfer of ink from one reservoir to the other reservoir.  Cross-flow purging of air or debris from the ink jet head is effected by covering the ink jet orifices (11) and applying air pressure to one reservoir to cause ink and any trapped air or debris to flow from the head to the other reservoir.  A pump responsive to reciprocal motion of the ink jet head generates a positive air pressure which is applied during purging and a negative air pressure which is applied to a deaerator for removing dissolved air from the ink.

Title: Condensate trap for system under pressure
Inventor: KOCH BERTHOLD
IPC: G05D9/12
Filed: 1990-03-29
Abstract: ABSTRACT OF THE DISCLOSURE           Condensate Trap for Systems Under Pressure In  a  so-called  condensate  trap  for  discharging condensate,  e.g.  oil  or  water  from  a  fluid  system which contains air or a gas or vapour under pressure, a single tube which projects into a housing in which the condensate  collects  contains  spaced  sensors  of  an electric  capacitive  type  sensing  the  maximum  level which the condensate is to be allowed to reach within the chamber and a predetermined lower level.  A signal from  the  upper  sensor  triggers  a  pilot  valve  which opens  a  diaphragm-type  discharge  valve  and  a  signal from the lower sensor initiates closing of the valve, but only after a time delay, allowing the condensate to fall first to a level below that of the lower sensor. This time delay is related to the time taken for the condensate to fall from the maximum level to that of the lower sensor.    The control unit and sensor tube form  a  self-contained  structural  assembly  for  easy installation and replacement.     In the floor of the housing forming the condensate collecting chamber there is a   weir or well to prevent sediment reaching the diaphragm valve.
Patent CA-2013733-A1 (CA)
Inventor: BRANDSTETTER ROBERT W
IPC: G03H1/16
Filed: 1990-04-03
Abstract: ABSTRACT OF THE DISCLOSURE            A multi-channel filter which exploits the parallel processing advantages of an optical signal processor is used to sort, classify and remove noise or unwanted signals from signals of interest.  This filter shall perform real time parallel signal processing to effectively channelize and remove unwanted spectra from the various signals of interest in a dense radio frequency environment.  This would in effect transform a single channel that is corrupted with unwanted signals, interference and noise, to a number of discrete channels which is spectrally tailored to selected signals of interest.  The filtering process is accomplished by modulating a laser carrier with the given signal of interest and performing all filtering functions optically and then down converting the filtered signals back into its original radio frequency for further use.
