Patent EP-0314109-A3 (EP)
IPC: A61K9/70
Filed: 1988-10-26
Abstract: There is described a biodegradable collagen flake product 
and a biodegradable collagen sponge or sponge-like material. 
The collagen flake product is characterized by collagen 
fibers of non-uniform size, length and thickness, which 
fibers form flakes which define non-uniform channels 
connecting the surface of the material with the interior, 
and the collagen flakes having interconnecting pores. The 
collagen sponge-like material is characterized in that it 
contains a cross-linked, three dimensional fiber network 
which defines channels which connect the surface of the 
material with the interior and randomly distributed pores 
open to the channels. The products and materials are use­
ful for medical applications, like skin reconstruction, 
treatment of wounds, especially deep wounds, also in 
connection with surgery, including cosmetic surgery.

Title: Process for preparation of liquid electrostatic developer
IPC: G03G9/12
Filed: 1988-11-01
Abstract: Improved liquid electrostatic developer 
containing electrostatic toner particles is prepared 
by a process wherein an aqueous, e.g., water-wet 
pigment cake is flushed with a water insoluble 
vehicle, water is removed, and the developer is 
formed from the flushed pigment dispersion, 
thermoplastic resin, dispersant nonpolar liquid 
having a Kauri-butanol value of less than 30, in a 
vessel at elevated temperature under high shear, and 
the dispersion is cooled. The liquid electrostatic 
developer is useful in copying, making proofs 
including digital color proofs, lithographic printing

Abstract: The carrier has a test layer (33) which contains a ligand which is immobilised on carrier particles and which reacts with a component of the liquid sample, in particular for immunological determinations. The test layer (33) is so porous that the liquid sample with the component can penetrate into it, reupo the ligand comes into contact with the component of the sample. 
<??>A test carrier of this type with improved production and use properties is obtained when the carrier particles consist of inorganic material, reactive organic groups are covalently bonded to their surface as coupling groups, and the ligand is covalently bonded to the coupling groups.

Title: Compositions and processes for producing scratch resistant polysiloxane coatings
IPC: C08J3/09
Filed: 1988-09-01
Abstract: A polysiloxane prepolymer is prepared in acidic 
aqueous solution to have a) polysiloxane-linkage-forming 
groups, b) non-reactive groups and c) co-reactive groups 
and thereafter is taken into essentially organic 
solution. Preferred solvents are benzene or toluene.

Patent EP-0360557-A3 (EP)
IPC: H04N9/75
Filed: 1989-09-19
Abstract: A method and apparatus for keying digital colour TV 
signals without exceeding the normal sampling frequency 
(13.5 MHz) and without obtaining a degraded image. A 
digital keying signal and a digital colour TV signal are 
supplied to upsamplers (10,12), respectively, which double 
the sampling frequency of the incoming signal by linear 
interpolation. The 27 MHz sampled outputs are keyed in 
multiplier (14). In one line to a switch (24) the 27 MHz, 
12 MHz bandwidth keyed signal is passed through low pass 
filter (16) and demultiplexer (18). The latter removes each 
alternate sample to provide a 13.5 MHZ signal of 6 MHz 
bandwidth. In a second line to the switch the keyed signal 
is demultiplexed to provide a signal which would have 
resulted without upsampling, which is then delayed (22). 
Edge detector (26) senses high frequency keying signals and 
controls switch (24). In the absence of such high frequency 
keying signals the signal to the second line to the switch 
is taken. Only the presence of high frequency keying is the 
signal to the first line employed. The invention is thus 
"transparent" to the viewer in the absence of high frequency 
keys.

form of a gel (G) and a liquid buffer. A plurality of 
driving electrodes (D n ) are arrayed in spaced relation 
to one another so as to contact the medium. A plurality 
of sensing electrodes (S n ) are also arrayed so as to 
contact the medium and are spaced relative to one another 
and to the driving electrodes. Each sensing electrode is 
preferably positioned radially inward of and paired with a 
single one of the driving electrodes. Electrical 
potentials are applied to selected ones of the driving 
electrodes (D n ) and means are provided for sensing 
electrical potentials at selected ones of the sensing 
electrodes (S n ) and for adjusting the applied potentials 
to maintain the sensed potential at a selected value at a 
sensing electrode of each pair. The apparatus may be 
programmably controllable so as to enable an electric 
field to be modulated in both amplitude and direction as a 
function of time.
