Patent EP-0320900-A3 (EP)
IPC: G03C8/08
Filed: 1988-12-14
Abstract: An improved process for preparing negative 
images from a photohardenable tonable element, 
wherein the unexposed photohardenable tonable element 
is tacky in a preselected temperature range, 
T₁-T₂, in which temperature range the exposed 
photosensitive tonable element is nontacky but 
wherein the exposed element is retackifiable at 
elevated temperatures above T₂. After imagewise 
exposure the unexposed areas have a colorless toning 
material applied to them at a temperature within the 
range T₁-T₂ to make them nontacky at temperatures 
of at least up to T₃, which is greater than T₂. 
After heating to an elevated temperature above T₂ 
but less than T₃ the exposed areas have a 
contrasting toning material applied to them to give a 
negative or reverse image.

Title: Magnetic tilt sensor
IPC: G01C9/06
Filed: 1988-12-27
Abstract: A magnetic tilt sensor has a permanent magnet 
having a surface coated with a magnetic fluid and 
housed in a hollow portion of a nonmagnetic case, and a 
magnetic sensing element arranged outside the bottom 
portion of the case. When the case is tilted or is 
abruptly moved, the permanent magnet in the case is 
relatively displaced. The magnetic sensing element 
detects this displacement. Since the nonmagnetic case 
is sealed by a cold welding method, workability and 
reliability can be increased. In addition, a cap 
having a predetermined weight covers the permanent 
magnet so that a response characteristic is improved.

material retaining the above-described microstructure of 
the porous carbonate echinoderm or scleractinian coral 
skeletal material but having a calcium to phosphorus 
Ca/P atomic ratio less than or greater than 1.6, such as 
a calcium phosphate material comprising dicalcium phos­
phate and/or tricalcium phosphate and having a calcium 
to phosphorus Ca/P atomic ratio in the range 1.0-1.5 
when the calcium hydroxyapatite material is reacted with 
said phosphate-contributing or phosporus-contributing 
moiety or a calcium phosphate material having a calcium 
to phosphorus Ca/P atomic ratio greater than 1.66 up to 
2.0 when the calcium hydroxyapatite material is reacted 
with said calcium-contributing or calcium oxide-contrib­
uting moiety and comprising tetracalcium phosphate.

Title: Multi-layered identity card with high durability
IPC: B42D25/00
Filed: 1990-11-30
Abstract: Multi-layered solid plastic identity card comprising a laminate of different plastic layers which is particularly resistant to environmental influences and effects of daily use and has high durability. The use of plastics which are stable at high temperatures, such as PC (polycarbonate), for the card core (3) and the outer sheets (1) ensures the dimensional and temperature stability even under extreme environmental conditions and the use of intermediate layers (2) of a thermoplastic elastomer such as TPU (thermoplastic polyurethane) minimises the risk of the card breaking, since these layers absorb stresses and shearing forces and make the card flexible. <IMAGE>
Patent EP-0428197-A3 (EP)
IPC: C12Q1/68
Filed: 1990-10-12
Abstract: This invention provides a rapid and highly 
effective method for extracting nucleic acids from 
cells or virions without the use of proteolytic 
enzymes. Extraction is accomplished within a few 
minutes using a lysing composition comprising a 
buffer, a source of a DNA polymerase cofactor, a 
stabilizer and at least one nonionic surfactant which 
will release nucleic acids from cytoplasmic and 
nuclear membranes of cells or from virions. The 
resulting mixture is heated to boiling for up to 
fifteen minutes, and the nucleic acids are recovered 
for amplification using polymerase chain reaction. 
No proteolytic enzyme is used in the extraction 
process.

Title: Atm-exchange
IPC: H04L12/54
Filed: 1991-01-26
Abstract: State of the art/technical problem: When a connection is set up by a switching network 20, the path is selected according to the instantaneous switching network utilisation and is maintained during the connection. The problem of eliminating local blockages through rearrangement of existing connections is not adequately solved due to interferences which thereby occur. Fundamental concept: To provide for ATM with virtual connections the same devices as those which guarantee the correct sequence in connectionless operation. Solution: An output unit 30 is connected downstream of each output of the switching network which guarantees the correct sequence. Advantage: Virtual connections can be adapted at any time without interference to the instantaneous switching network utilisation. The guarantee of the correct sequence can be implemented in such a way that delay jitter is also largely eliminated. <IMAGE>

Title: Demagnetisation circuit for the picture tube in a television receiver
IPC: H04N9/29
Filed: 1991-12-13
Abstract: 2.1. In HDTV sets having a 16:9 picture tube, it is required to completely switch off the decayed demagnetisation current by means of a relay. It is known to control the relay from the secondary side of the switched-mode power supply. The relay contact is then on the mains-connected hot side and the relay winding is on the mains-isolated cold side of the switched-mode power supply. A relatively expensive relay must therefore be used which has a dielectric strength according to VDE. It is the object to modify the circuit in such a manner that a relay can be used which does not have any special requirements for dielectric strength. 
<??>2.2. The relay winding (A) is connected in series with the primary operating winding (5) of the switched-mode power supply and is bypassed by an NTC resistor (14). 
<??>2.3. Particularly for television sets with a 16:9 picture tube.
