Patent EP-0312511-A3 (EP)
Title: Control mechanism for controlling the water supply in an irrigation system and similar, operating by means of pressure pulses
IPC: A01G25/16
Filed: 1988-10-14
Abstract: The mechanism prevents erroneous commands caused by 
brief accidental pulses and comprises, in conjuction 
with a rotary shutter (10) that moves intermittently, 
a chamber (3, 3A) with a float (5) connected to said 
shutter, the pressure on which is generated by the 
arrival of fluid and the resultant filling of said 
chamber; a discharge device (30, 34) causes said chamber 
to empty slowly within a period of time that is not less 
than a predeterined limit and which starts when the 
working pressure is released; cam devices (40, 42) cause 
a one-step movement of said shutter only when said chamber 
is completely empty.

Patent EP-0368507-A3 (EP)
Title: Stable color dispersions, their preparation and use in ceramic glazes
IPC: C03C8/00
Filed: 1989-10-25
Abstract: A colored ceramic glaze is prepared from a raw 
glaze containing glass frit, clay and one or more cera­
mic pigments added as an aqueous dispersion. The raw 
glaze is ball-milled after which it is blended with the 
aqueous dispersion. The dispersion contains up to 70% 
of a ceramic pigment, such as zirconium-vanadium yellow, 
preferably with 1% to 3% of a suspending agent, up to 
about 1.5% of a thickener, an effective amount, but no 
more than 1% of a dispersant, and a biocide as needed. 
The suspending agent preferably is attapulgite clay or a 
water-swellable smectite clay. The thickener is prefer­
ably a xanthan gum and the dispersant is typically an 
ammonium salt of a medium molecular weight polymethacryl­
ic acid. A stronger, more intense color is achieved by 
adding the ceramic pigment as a dispersion as opposed to 
ball-milling it with the glass frit as has been the 
traditional approach.
