Patent EP-0320127-A3 (EP)
IPC: G03F7/029
Filed: 1988-11-14
Abstract: This invention relates to photoinitiator systems 
for use in addition, i.e., free radically-initiated, 
polymerization.  
     Photopolymerizable compositions usually contain a 
photoinitiator system, a polymerizable monomer, and 
optimally adjuvants. Often pigments are added to color or 
opacify the composition. The addition of pigments usually 
inhibits the initiation of polymerization because of 
competitive light absorption or light scattering, which 
decreases the amount of light available for absorption by 
the photoinitiator system. It would be desirable to be able 
to use pigments in combination with or as part of a 
photoinitiator system in a photopolymerizable composition.  
     This invention provides photopolymerizable 
compositions comprising: 
   (1)at least one vinyl monomer capable of 
undergoing free radical polymerization,    (2)a visible light or ultraviolet light responsive 
photoinitiator system comprising:    a) a diarylidonium salt,    b) a pigment, insoluble in the 
photopolymerizable composition, said 
pigment also serving as a sensitizer,    c) one or more electron donating 
compounds,and, optionally,    (3) adjuvants.     
     The three component photoinitiator system of this invention 
can increase, by several orders of magnitude, the rate of 
ultraviolet light or visible light photocuring of vinyl 
monomers.

Title: Bandwidth reduction for the transmission of television signals
IPC: H04N11/16
Filed: 1988-12-30
Abstract: A colour television signal is transmitted with bandwith 
reduction. A luminance encoder (10) has two paths with different 
sub-samplers (14) introducing different bandwidth reduction methods. 
The sub-sampled signal is restored in filters (16) similar to those 
(34) at the receiver and the path which introduces least error is 
used for transmission. The selected path is determined on a 
block-by-block basis and an indication of the paths used for each 
block digitally transmitted (26) in DATV format. Bandwidth 
reduction is also applied by encoders (42) to the U and V colour 
component signals. Several options exist using one or more coding 
paths and making the choice of coding path the same as for the 
luminance component, the same for the two colour components, or 
different for all three, or some other function.

IPC: C12Q1/6834
Filed: 1989-08-24
Abstract: A method is disclosed for detecting the presence of 
a target nucleotide sequence in a polynucleotide. The

Patent EP-0377551-A3 (EP)
IPC: H04B3/54
Filed: 1990-01-03
Abstract: Outbound signals carried over an electric 
power network are detected and crosstalk is rejected by 
sampling the waveform (V) in three segments (I, II, 
III) of each cycle. In the first segment (I) valid 
signals are always absent. Valid signals appear at the 
same time in both the second and third segments (II, 
III). Sample waveform values from alternate half cycles 
are compared to detect differences indicative of 
outbound signal information. The energy in each of the 
three segments (I, II, III) is compared with an energy 
threshold for that segment and a cycle under test is 
rejected when the energy in the first segment (I) 
exceeds the threshold for that first segment (I). A 
cycle under test is also rejected if the energy in the 
third segment (III) greatly exceeds the energy in the 
second segment (II). Signal detection thresholds for 
both signal strength and energy in the segments (I, II, 
III) are set recursively using actual samples acquired 
at the outbound detection site. These thresholds are 
sensitive to dynamic network changes.

An intermediate, generally tubular wrapper with two end parts and a central part in which the body is situated is thus formed. Rotary pincers provided with pairs of clamping fingers act on these two end parts to form bow-like twists. The preferred application is for wrapping food products such as sweets and the like.
