Patent EP-0208450-A3 (EP)
IPC: C12H1/075
Filed: 1986-06-20
Abstract: It has been proposed to filter beer or tank bottoms using 
crossflow filtration. In accordance with the invention, this 
crossflow filtration is achieved using ceramic membranes. In 
a particular form shown in figure 1, a two stage filtration pro­
cess combines the functions of clarification and recovery from 
tank bottoms. Beer is drawn from a tank 1 by a centrifugal 
pump 2 to a primary filtration stage comprising a circuit in­
cluding a circulating centrifugal pump 3, a ceramic membrane 
filter 4 and a cooler 5. A proportion of the circulating liquid is 
drawn off by a positive pump 8, and passed to a secondary 
filtration stage, again comprising a circuit including a circulat­
ing positive pump 9, a ceramic membrane filter 11 and a coo­
ler 12. A proportion of the retentate is drawn off via a line 14. 
This retentate is of a pasty consistency and normally has a 
commercial value, in that it is free of kieselguhr or other filter 
aid.

Title: Regenerative burner system
IPC: F27D99/00
Filed: 1988-12-16
Abstract: A regenerative burner system comprises two burners alternately fired 
and each having an air and fuel supply thereto traversing separate 
heat exchangers. The arrangement is such that the hot gases 
exhausted from the furnace during firing of the one and the other 
burners traverse the heat exchangers associated with the other and 
the one burners, respectively, relinquishing heat thereto whereby 
both the fuel and the air supply to each burner extracts heat from 
its associated heat exchanger during the firing cycle of that 
burner.  
     By heating both the fuel and the air input to the regenerative 
system, fuels of low calorific value, e.g. blast furnace gas or any 
gases low in or devoid of hydrocarbons may be efficiently utilised 
to provide a stable high temperature flame without the need for 
enrichment with 'pilot' fuels.
Patent EP-0287348-A3 (EP)
Title: In situ monitoring of corrosion rates of polarized or unpolarized metals
IPC: G01N27/26
Filed: 1988-04-13
Abstract: The electrochemical parameters that are necessary to calculate the corrosion rate are contained in the harmonic current response to a moderate amplitude sinusoidal voltage perturbation applied to the corroding metallic component (W) in an electrolytic cell (26). The harmonic current response is analyzed at frequencies 1f, 2f, 3f, 4f, 5f and the rectification current response at DC current to the presence of a 20-50 mV AC voltage perturbation at a frequency f. The free corrosion current density, the free corrosion potential and the Tafel coefficients are calculated. The Tafel coefficient is a measure of the exponential dependence at the rate of corrosion in a material. From these data, the dissolution current is calculated, which in turn is integrated with respect to time to yield a cumulative mass loss. The corroding metallic component (W) in the electrolytic cell (26) is supplied a.c. and d.c. current under the control of a microcomputer (12) and the response is analyzed by a frequency response analyzer (10) coupled to the cell (26) through a potentiostat (24).

Patent EP-0376330-A3 (EP)
IPC: H04N5/14
Filed: 1989-12-28
Abstract: An arrangement for detecting movement in a picture 
displayed on a television display. Y/C color separation 
detects movement in a displayed picture by generating a first 
movement detection signal with respect to luminance, a second 
movement detection signal with respect to luminance and a 
movement detection signal with respect to color. The first 
movement detection signal with respect to luminance 
represents the difference between a luminance signal 
extracted by Y/C separation in a first frame and a luminance 
signal extracted by Y/C separation in a second, adjacent 
frame. The second movement detection signal serves as an 
auxiliary detection signal, and indicates any leaking of the 
color signal into the luminance signal after Y/C separation. 
The auxiliary signal, which indicates the leakage of any 
color signal into the luminance signal, is able to minimize 
erroneous detection of movement due to leakage of the color 
signal.
