Title: Source volt-ampere/load volt-ampere differential converter
IPC: H02M3/335
Filed: 1988-01-06
Abstract: A source V-A/load V-A differential converter (single quad­
drant DC-DC topology) combines the canonical functions of both 
the boost and buck converter topologies. Basic advantages of the 
boost and buck topologies are retained, disadvantages of these 
and prior art compound topologies are eliminated, and several 
entirely new and useful functions are realized. These new func­
tions include sub-microsecond source voltage/load step response 
(independent of feedback loop parameters), extremely wide source 
voltage range, very high conversion efficiency/power density, 
multiple auxiliary outputs with closely held voltage range para­
meters (without resort to minimum load, pre-load, or sub-regula­
tion), galvanic input/output isolation, enhanced capacitance 
safety/energy storage, reduced gain bandwidth requirements, and 
intrinsic stability. The differential term derives from the 
transfer funtion for this new compound topology, i.e., x=δ(a+x).
Patent EP-0317289-A3 (EP)
IPC: F16H61/40
Filed: 1988-11-16
Abstract: A method of controlling speed reduction ratio for a 
continuously variable speed transmission comprises a running mode 
control method which is carried out when an accelerator opening 
is opened, an engine brake mode control method which is carried 
out when said accelerator opening is substantially closed and a 
transient control method which is carried out over a 
predetermined period of time (TEB) when the control is shifted from a 
state under the engine brake mode control to a state under the 
running mode control. The transient control method comprises the 
steps of obtaining a corrected R-REF engine speed immediately 
after the shift to the running mode control (S4,S6), by adding a 
difference (OFFSET) between the actual engine speed and the R-REF engine 
speed to the R-REF engine speed set corresponding to the 
current accelerator opening, obtaining a further corrected R-REF 
engine speed during a predetermined period of time (TEB) following the 
shift (S11,S6), by adding a correction which is obtained by gradually 
decreasing the speed difference with time (S9,S10,S11) to the R-REF engine 
speed, and controlling the speed reduction ratio (57) so that the 
actual engine speed coincides with the corrected R-REF engine 
speed over the predetermined period of time.

Patent EP-0349166-A3 (EP)
IPC: G21D3/00
Filed: 1989-06-15
Abstract: This invention is a system that provides 
spatially dependent, electromagnetic type diagnostic 
information to a computer based procedures execution 
monitoring and guidance system. The computer based 
procedures execution and monitoring system 22 and 24 
automatically selects procedures for performance by a 
human operator 26 based on the diagnostic information. A 
spectral analyzer 16 obtains spectra from fluid sources 
which are used by a computer 22 to determine whether to 
trigger a procedure to correct any abberations discovered 
by comparing the spectra to known reference spectra. A 
pyrometer 14 monitors process temperature as compared to 
various thresholds and the computer 22 triggers a 
procedure if the temperature is not normal. An image 
processing system 30 and 32 monitors status lights, 
meters, valve positions and other visual information from 
status displays 20. The signature features from the image 
processing computer 30 are compared to reference features 
to determine whether a procedure should be triggered. 
When a procedure is triggered, the operator 26 monitors 
and follows the procedure to change the state of the plant 
10. The optical interfaces are used by the procedure 
computer 22 to monitor the changes in the plant condition 
calling up other procedures or changing the displayed 
procedures as needed and confirming plant 10 response to 
operator control actions. This feedback allows the 
operator 26 to concentrate on the judgmental task 
 
 
associated with bringing the plant 10 back to a nominal 
operating condition without requiring the operator 26 to 
monitor an entire control room.

Title: Dissolving and deaerating method
IPC: B01D19/00
Filed: 1990-06-19
Abstract: A method of dissolving a powder material is 
disclosed in which the material is wholly dissolved 
and the existence of bubbles in the resultant solution 
is greatly minimized. An agitating blade stirs a 
liquid in an air-tight tank while the powder material 
is inserted into the liquid. The pressure is then 
reduced in the tank causing large bubbles to swell. 
The bubbles are destroyed by the agitating blade. The 
pressure reducing operation is then turned off so that 
the bubbles do not leave the tank through a pressure 
reduction port. The pressure reducing operation is 
then repeated a number of times to dissolve the powder 
material and to destroy bubbles.
