Patent EP-0211547-A3 (EP)
Title: Comminution of material
IPC: B02C23/26
Filed: 1986-07-17
Abstract: Material is comminuted in a substantially dry state in a chamber (4) as a result of agitation by a rotor. During the process, gas is admitted to the chamber (4) through a foraminous base (8) to flow upwardly in a uniform manner across the cross-section of the chamber. Pulses of gas are directed periodical­ly at the material through inlets (15) to prevent agglomeration of the material. The pressure of the gas admitted through the inlets (15) is higher than that admitted through the foraminous base (8). Surface active agents may be added to the material, also to prevent agglomeration, as well as, or instead of the use of pulsed gas.
Patent EP-0216552-A3 (EP)
IPC: B29L30/00
Filed: 1986-09-05
Abstract: A tire curing press with an improved loader includes a 
shaping or center mechanism which includes a vertically 
movable well (17) on which is mounted the bottom bead or 
toe ring (16). The press includes a loader of improved design 
affording precision centering and accuracy which is driven for 
vertical movement by a ball screw (80) and nut drive which 
positions the green tire concentric with the upper and lower 
mold sections and over the bottom bead ring. The loader then 
moves the green tire downwardly until the lower bead of the 
green tire reaches a predetermined point touching or fairly 
closely adjacent the elevated bead ring. Simultaneously, an 
adjustable pad on the loader contacts the tip of an extended 
rod of a vertically oriented synchronizer piston-cylinder 
assembly (147). Concurrently, a sensor is tripped to power the 
synchronizer piston downwardly and as such piston moves 
downwardly, the loader follows at a slightly higher speed 
causing the rotary motor of the ball screw drive to be retarded 
or stall, thus keeping the loader in contact with the tip of the 
rod of the synchronizer cylinder assembly. As the synchroniz­
er piston is being powered down, fluid on the underside of 
such piston is being forced over to the top ports of a pair of 
bead lift cylinder assemblies (24,25) causing them to bring the 
well (17) and thus the lower bead ring down at the same speed 
as the loader is bringing the tire down. In this manner the 
green tire and lower bead ring are maintained in constant 
relationship until the bead ring is seated on the lower mold 
section. The point of bead ring seating provides a physical 
stop which in turn blocks the synchronizer piston and rod, and 
thus the loader from further downward travel. This synchroni­
zation is accomplished by making the blind end area of the 
piston of the synchronizing cylinder assembly twice the equal 
rod end areas of the pistons of the bead lift cylinders.

Title: Optical fibre cable
IPC: B29D11/00
Filed: 1986-09-25
Abstract: An optical fibre cable element (3A) for incorporation in an optical fibre cable (Fig. 4) for e.g. local area networks, comprises a plurality of optical fibres (3) held together solely by an adhesive which has been applied cold and air-dried. A suitable adhesive material is a solvent-based acrylic copolymer system. Preferably the shape of the cable element is a ribbon, but other constructions are also envisaged. The cable element is cheap to make and avoids the heat and pressure of extrusion in the construction of the cable element, thus minimising the risk of damaging the fibres by such heat and pressure. Very high fibre density is also achieved.

Patent EP-0245081-A3 (EP)
IPC: C08F212/04
Filed: 1987-05-05
Abstract: Copolymer beads made by suspension copolymerisation 
of styrenic monomer with divinylbenzene under conditions 
such that the products have defined solubility, gel content, 
molecular weight and bead size characteristics which enable 
their use (after impregnation with a blowing agent and pre­
expansion) in molding into foamed cups over a much broader 
range of time and temperature and the resultant cups are stiffer 
per given weight than cups made from conventional poly­
styrenes utilised for making foamed cups. These advantages 
are realised without any sacrifice in cup appearance.

Patent EP-0259133-A3 (EP)
IPC: C12Q1/04
Filed: 1987-09-01
Abstract: The interference of dehydroascorbic acid, an 
oxidation product of ascorbic acid, in analytical 
methods is reduced with the use of certain 
nitrogen-containing organic buffers. Dehydroascorbic 
acid tends to cause premature reduction of reducible 
compounds which are used to provide detectable 
species in the presence of an analyte. These organic 
buffers, as opposed to inorganic buffers, prevent 
premature reduction of the reducible compounds. An 
analytical method can be carried out in solution or 
in a dry analytical element.
Patent EP-0273581-A3 (EP)
IPC: H03G5/16
Filed: 1987-11-24
Abstract: A method and apparatus are disclosed which provide 
for the removal of distortion present in a digital output 
signal from a linear analog signal processing system. Two 
applications are disclosed: digital compensation and 
digital equalization. Digital compensation provides for 
the removal of distortion from a single signal processing 
system. In particular, an adaptive digital filter 
operates to provide processing of an output signal from 
the signal processing system in accordance with correction 
criteria determined by a controller in response to a 
training signal. Digital equalization is employed with 
respect to a plurality of signal processing systems, and 
provides equalization of an output signal from one signal 
processing system in accordance with characteristics of a 
selected signal processing system. In particular, output 
signals from a selected signal processing system and a 
signal processing system desired to be equalized are 
employed to provide information to a controller for use 
with a correction criteria in the determination of 
correction information. The correction information is 
used to direct an adaptive digital filter coupled to an 
output of the signal processing system which is desired to 
be equalized.

Patent EP-0370406-A3 (EP)
Title: Direct current restorer
IPC: H04N5/14
Filed: 1989-11-17
Abstract: The present invention provides a direct current 
restorer applied to a pedestal clamp circuit of a 
television receiver or the like, in which an input 
video signal is compared with a pedestal level setting 
reference signal for every pedestal period, and, based 
on difference between the pedestal level of the input 
video signal and the level of the reference signal, 
the direct current level of the input video signal is 
shifted. In this direct current restorer, a direct 
current according to the level variation of the ref­
erence signal may be superposed on the input video 
signal so that the direct current level of the input 
video signal is corrected according to the level 
variation of the reference signal. Accordingly, when 
adjusting the pedestal level or achieving a liquid 
crystal display in which the polarity of the input 
video signal is periodically inverted, a direct cur­
rent according to the level variation of the reference 
signal may be superposed on the input video signal. 
Thus, the pedestal level of the input video signal may 
quickly follow the level variation of the reference 
signal and may be controlled to the level of the ref­
erence signal with no influence exerted onto the com­
parison in level of the input video signal with the 
 
 
reference signal. Accordingly, when this direct cur­
rent restorer is applied to, for example, a drive cir­
cuit for a liquid crystal panel such as a liquid 
crystal television receiver or the like in which the 
input video signal is periodically changed in polari­
ty, a stable direct current restoration may be a­
chieved.
