Patent EP-0204403-A3 (EP)
IPC: B05D1/04
Filed: 1986-04-09
Abstract: Uniform application of a controlled relatively small liquid 
volume per unit area to a moving fabric substrate is obtained 
even though application is made using a liquid jet electrosta­
tic applicator which employs random drop formation proces­
ses. Repetitive print times during which randomly formed 
droplets are passed onto the substrate along a linear orifice 
array are controlled so as to have a minimum duration suffi­
ciently large as to average out expected random variation in 
droplet formation processes occurring along the orifice array. 
At the same time, the center-to-center spacing of each printed 
pixel (during which randomly formed droplets are intercepted 
so as not to fall onto the substrate) is controlled so as to 
maintain a desired relatively small controlled liquid volume 
per unit area within the fabric substrate section to be printed. 
In one exemplary embodiment, the print times are maintained 
in excess of approximately 200 microseconds and/or so as to 
insure that the expected standard deviation of liquid volume 
printed onto the substrate during each print time is less than 
approximately 0.2.

Filed: 1986-04-22
Abstract: Apparatus for use in testing the mechanical behaviour and deformation characteristics of rocks and the like at various locations in a borehole comprises a pressure intensifier (14) used in con­junction with a dilatometer head (11), the two being rigidly interconnected so as to be lowered into the borehole (12). The pressure intensifier (14) com­prises a cylindrical housing (20) providing upper and lower cylinders (22),(23), and a double action piston (24) which provides a 6 to 1 differential between the input pressure side and the output pressure side. Pressure changes are measured by means of a pressure transducer (37), and volumetric changes are determined from measurements of the linear displacement of the piston. Such linear displacements are measured by means of a shaft encoder (41) coupled to a motion translating device (43) for translating linear displacement into rotary displacement.
Patent EP-0209302-A3 (EP)
IPC: G01L1/00
Filed: 1986-07-04
Abstract: Internal stress on an object being electroplated is 
monitored continuously with a gauge. The gauge includes a 
metal receptor which is employed as a second cathode in the 
electrodeposition process. A separate plating current is 
supplied between the anode and second cathode, distinct from 
the separately controllable current between the anode and 
object being plated or electroformed. The stress on the second 
cathode is measured with a strain gauge, and a stress deviation 
from a desired plating stress is determined. The currents 
between the anode and first and second cathodes are adjusted 
in accordance with the measured internal stress on the metal 
receptor to achieve a desired stress condition.  
     The internal stress is advantageously monitored with a foil 
resistance strain gauge. The strain gauge is connected to a 
carrier disposed in parallel with the metal receptor. The carrier 
is rigidly connected at opposite ends to the metal receptor. A 
stress transmission link centrally located between ends of the 
metal receptor and the carrier transmits the force applied by the 
electroplating material on the receptor to the carrier. The strain 
gauge provides an indication of the stress which results from 
the electroplating. The currents between the anode and first 
and second cathodes may be controlled in accordance with this 
stress measurement.
