Patent EP-0228081-A3 (EP)
Title: Publicity letter
IPC: B42D15/08
Filed: 1986-12-24
Abstract: The letter is formed from a continuous rectangular carrier web (5). Said web has at least two tear-off edge strips (18; 19) which can be separated from the other surface areas (A1 ... A6) of the carrier web (5) by means of longitudinal perforations (16; 17). The carrier web (5) is folded together at least along two transverse folding points (11 ... 15) to form a folded letter. In this case, adhesive applications (25; 26) are mounted on some surface areas of the tear-off edge strips (18; 19), by means of which adhesive applications the adjacent surface portions (A1 ... A3; A4 ... A6), which are folded onto one another, are held together as long as the tear-off edge strips (18; 19) are not separated. Further adhesive applications, for example to form a return envelope, may be mounted inside the tear-off edge strips (18; 19). At one or more points in each case between two adjacent surface portions (A2, A3; A3, A4; A5, A6) there is in each case an incision (21; 22; 23) extending in the transverse direction from one longitudinal perforation (18) to the other longitudinal perforation (19). <IMAGE>

Patent EP-0223707-A3 (EP)
IPC: B01F23/70
Filed: 1986-11-13
Abstract: A compressed carbon fiber aggregate has a 
ball-shaped, elongated ellipsoidal or cylindrical 
configuration made up of individual carbon fibers. The 
carbon fiber aggregate is produced without the need for 
a binder but is made sufficiently dense by compression 
into the ball-shaped, ellipsoidal or cylindrical 
configuration.To produce the aforementioned carbon fiber 
aggregate with increased density, loose carbon fibers 
are circulated by means of a gas, such as air, within a 
circular chamber (10). As they are being driven around the 
circular chamber by the gas, individual carbon fibers 
separate and then reaggregate into a more compact 
ball-shaped or ellipsoidal configuration. By performing 
the aforementioned process for a sufficient period of 
time, e.g. 10 to 20 min., a ball-shaped or ellipsoidal 
carbon fiber aggregate with a density sufficiently high 
for gravity-feed can be obtained. The obtained carbon 
fiber aggregates may be of essentially uniform size and 
density.

Abstract: A system is provided for the input, retrieval, manipulation 
and analysis of stored information in an information base. The 
system comprises an input device (22), a storage device (14), and an 
output device (34) each capable of handling information 
elements. Each of the attributes of the information 
elements is processed to produce a compact symbol or 
code corresponding to predefined ranges of values of an 
attribute. These codes are then stored in 
correspondence with the information elements which gave 
rise to them. The result of this processing is a 
topological map (16) of the attributes of the information 
elements. These topological maps (16) may be retrieved and 
later processed to efficiently retrieve stored 
information elements, given any general unpreprogrammed 
query as input to the system. These topological maps (16) 
may also be utilized in a process to determine 
correlations among the various attributes of the 
information elements.

Filed: 1988-08-23
Abstract: A method and apparatus for creating a transitive closure of a database 
when the database is stored on a secondary storage in the form of links connecting 
nodes. The method consists of partitioning the database, transferring one partition 
at a time from the secondary storage to the main memory, and processing a 
partition in such a way that accesses to the portions of the database not in main 
memory are minimized. As much of the unprocessed database as would fit a 
predetermined fraction of main memory is fetched as one partition, and if, during 
the processing of this partition, the main memory becomes full, the size of the 
partition is reduced dynamically by discarding a portion of the database in the 
current partition, and including this portion in the next partition. The processing 
of a partition involves, for each node in the partition, the operation of creating a 
direct connection between every pair of nodes that are indirectly connected 
through this node.

Title: Filter
IPC: H03H17/06
Filed: 1989-10-03
Abstract: In a sub-band coder having several filter stages, the  problem exists to keep disturbances, which are produced by data reduction or quantization noise in one sub-band, out of other sub-bands in which these disturbances do not originally occur. Such disturbances occur when the noise components are reflected. According to the invention, the filter stages are dimensioned in such a manner that their transition areas do not overlap at any point in the frequency band. The stop-band corner frequencies of the individual filter stages are preferably identical. The filters can be used in sub-band coders, preferably for data reduction in digital broadcast transmission.
