Patent EP-0296610-A3 (EP)
IPC: C09C3/00
Filed: 1988-06-24
Abstract: The present invention provides a glycol dispersion of 
calcium carbonate prepared by wet grinding a glycol slurry 
composed of glycol and calcium carbonate surface-treated 
with (A) a copolymer of at least one α,β-monoethylenically 
unsaturated carboxylic acid or a salt thereof with an 
α,β-monoethylenically unsaturated carboxylic acid ester 
and/or (B) a salt of a copolymer of an α,β-monoethyl­
enically unsaturated carboxylic acid with an α,β-mono­
ethylenically unsaturated carboxylic acid ester. The 
glycol dispersion of the present invention has good 
dispersion stability in glycol as well as affinity to 
polyester and contributes to improving the surface 
properties of the polyester product. Furthermore, proper 
selection of a specific grade of calcium carbonate and 
specific grinding conditions enable the provision of high 
performance polyester products.

Abstract: An electric storage battery is provided having a 
monitoring device for indicating the state-of-charge 
of the battery and particularly indicating whether a 
discharged battery is healthy and capable of being 
recharged or unhealthy and impending on a state of 
failure. The monitoring device achieves the 
foregoing by testing the open circuit voltage of the 
battery and determining if the voltage of the battery 
drops below a first preset value after application of 
a load and subsequently fails to rise above a second 
preset value after the load has been removed. Also, 
the monitoring device for the battery includes the 
capability of sensing when the battery has been 
placed into a system such as an engine system for an 
automobile and in response thereto modifying testing 
certain parameters. Preferably, the monitoring 
device is made integral with the battery case by 
providing a receptacle for receiving the device and a 
pair of connecting arms at least partially embedded 
in the battery container or cover.

Title: Luminance/chrominance signal separation circuit for pal color television signal
IPC: H03H15/00
Filed: 1989-10-17
Abstract: A circuit for separating a PAL color television 
signal into a luminance signal and color difference 
signals. The PAL color television signal is sampled (2) 
in phase coinciding with color burst and at a sampling 
frequency four times as high as that of chrominance 
subcarrier. A part of the sampled signal is delayed for 
one frame by a frame memory (4), and difference between 
the sampled signal and the one-frame delayed signal is 
determined by a subtraction circuit (6). The one-frame 
difference signal is then divided into first and second 
inter-frame difference signals (b). From the first 
inter-frame difference signal (b₁), motion information 
is detected by a detector (8) for controlling a mixing 
ratio of a mixer circuit (9) serving for mixing the 
second inter-frame difference signal (b₂) and an interline 
difference signal (a). From the output of the mixer 
circuit, chrominance signal is demodulated (10) for every 
other pixel and interpolated (11) for the interposed 
pixels to obtain the color difference signals.
