Patent EP-0147989-A3 (EP)
IPC: G01N27/407
Filed: 1984-12-14
Abstract: An air/fuel ratio detector comprising a pump (3) and an 
electrochemical cell (10) in which both the pump and 
electrochemical cell comprise an oxygen ion conductive 
solid electrolyte (6, 13) sandwiched between porous elec­
trodes (4, 5; 11, 12). One of the elements (10) has an 
insulating substrate (16) formed on a portion of the electro­
lyte. Over the substrate (16) is formed a layer of semicon­
ducting metal oxide (17). The cell and pump face each other 
with the cell providing an EMF and the pump being pumped 
by a pump current. The size of the resistance of the metal 
oxide layer indicates whether the air/fuel mixture is rich or 
lean relative to a stoichiometric mixture and the values of the 
EMF and pump current indicate the deviation from 
stoichiometry.

Patent EP-0220354-A3 (EP)
Title: Loudspeaker combination with piezo-electric tweeter
IPC: H04R1/24
Filed: 1985-09-09
Abstract: This invention concerns a multiple loudspeaker with a piezo-electric "tweeter", held up by a means of support which allows the rear wave emitted by the ceramic disk and respective conical diaphragm to be fully exploited, using the main loudspeaker cone as a reflecting surface without overloading the moving coil of the latter. The invention is basically characterized by the fact that the piezoelectric "tweeter" is placed in front of the main loudspeaker cone, without the traditional protection and support basket, but using a different means of support which does not intercept or disturb the rear radiation from the piezoelectric "tweeter", or prevent the forward reflection of the radiation by the main loudspeaker diaphragm.

Patent EP-0222993-A3 (EP)
Title: Sensitivity-calibration circuit for absorption analyzers
IPC: G01N21/35
Filed: 1986-08-27
Abstract: The sensitivity-calibration circuit for absorption analyzers comprises two separate temperature-compensation circuits (A, B), one (A) for compensating the temperature-drift resulting from the optical system of the analyzer and the other one (B) for compensating the temperature-drift caused by a sample system of the analyzer. The latter mentioned temperature-compensation circuit (B) can be blocked-off from operating on a checking and/or measuring input signal (VIN) by use of a switch (SW) such that during a measuring state both temperature-compensation circuits (A, B) are cooperating in sequence whereas during a specific checking state by switching over switch (SW) only said temperature-compensation circuit used in connection with checking the optical system is actively operating on said input signal (VIN). The advantage over the prior art combination sensitivity-calibration circuits is a more accurate and reliable calibration of the absorption analyzer during both, the measuring state and the checking state of the whole system.

Filed: 1989-04-25
Abstract: A weft treatment system and method for removing 
a mispicked weft yarn from a weft path of a fluid jet 
loom of the type wherein a weft yarn from a weft 
supply member is introduced through a weft storage 
unit to a weft inserting nozzle to be picked. With 
this system and method, a mispicked weft yarn is 
detected when mispick occurs. Then, cutting function 
of a cutter and weaving operation of the loom are 
stopped. Subsequently, the loom is reversely run to 
expose the mispicked weft yarn at the cloth fell of a 
woven fabric. The thus exposed mispicked weft yarn 
is drawn through the weft storage unit by a weft 
traction device disposed between the weft supply 
member and the weft storage unit.
