Patent EP-0355053-A3 (EP)
Title: Process for assessing wax settling in a fuel
IPC: F02B3/06
Filed: 1989-08-09
Abstract: The amount of settling of crystallised wax in a fuel 
e.g. diesel fuel at low temperatures may be more quickly 
assessed by cooling the fuel more rapidly, by centrifuging 
the cooled fuel and observing the volume of settled cloudy 
material. Results obtained in a few hours correlate well 
with results obtained using a three to five day test which 
simulates conditions of crystal formation and settling in a 
fuel tank.

Patent EP-0402113-A3 (EP)
Title: Vco frequency control circuit
IPC: H03L7/14
Filed: 1990-06-06
Abstract: A means for setting the free-running frequency of a voltage controlled 
oscillator (VCO) (12) without requiring laser trimming or the like is 
described. The VCO forms part of an interconnected phase-locked loop 
(PLL) and frequency-locked loop (FLL). At system power on, the PLL is 
automatically disabled and a digital-to-analog (DAC) (11) in the PLL is 
set to a value corresponding substantially to the centre of a 
preselected lock range. The FLL, which includes a second DAC (10), then 
operates to generate a bias voltage for incrementing or decrementing the 
VCO output frequency until the VCO pulse count stored in a register 
equals an expected count; whereupon the VCO will be set at its 
free-running frequency.  
     When the PLL is enabled, a phase error generator (14) generates a 
digital phase error signal from the input data. A digital integrator 
(19) converts the phase error signal to a digital frequency error 
signal. These error signals are added and the result is supplied to the 
DAC in the PLL for providing an analog output indicative of PLL 
frequency error. The outputs from both DACs are summed and the 
resultant current is converted to a bias voltage to adjust the VCO 
frequency as necessary for normally maintaining it within said lock 
range.  
     If the VCO frequency deviates from said range, the frequency error 
signal to the PLL DAC is zeroed, and the frequency error signal is 
supplied to the FLL DAC. The phase error signal from the PLL DAC and 
the signal from the FLL DAC as modified by the frequency error signal 
are summed, and the resultant current in converted to a bias voltage to 
adjust the VCO frequency to within said lock range.
