Patent EP-0237745-A3 (EP)
IPC: G06F9/44
Filed: 1987-02-03
Abstract: The hierarchical information is annotated by selectively adding to it 
two spatial representing characters. Each instance of a first spatial 
representing character corresponds to a unit step to the right, each 
instance of a second spatial representing character represents a unit 
indentation to the left, and the first instance of the second spatial 
representing character in a string of the second spatial representing 
characters may also imply a carriage return and line feed. The annotated 
hierarchical information is then stored (R1) and is scanned to produce 
two byproduct strings. The first byproduct string (R2b) is merely the 
sequence of first and second spatial representing characters, in the 
order in which they appear, to which is added two place holding 
characters, one representing an alpha-numeric string, and the second 
representing a string of one or more blank or null characters. The 
second byproduct string (R3b) is merely the concatenation of the 
alpha-numeric strings appearing in the hierarchical information. The 
first and second byproduct strings are then stored. The method is 
reversible so that the encoded and stored hierarchical data structure 
(including its contents) can be retrieved and reconstituted (R4). The 
encoded stored hierarchy (and its contents) can also be rapidly searched 
(SL) in its encoded form.

IPC: B65D57/00
Filed: 1987-12-01
Abstract: When packing placed together glass plates (1) or 
similar fragile plates, it is desirable to avoid 
damage to the plates during transportation in the 
package. For the protection of such stacks of glass 
(2, 3), corner pads can be used which are constructed 
of identical halves of a shock and impact absorbing 
expanded plastic.  
     Each half consists of one side piece (4) which is po­
sitioned in the space between the glass stacks (2, 3) 
and which at their ends are each provided with two 
end pieces (5, 6) resting on the end faces of the 
glass.  
     In order to hold together the halves and control 
these during the pushing together, each is provided 
with projections (8) and corresponding recesses (7), 
respectively, on the abutting side faces. If several 
corner pads are to be assembled, laterally reversed 
corner pads must be used on the opposite side of the 
glass stacks (2, 3).  
     In order to further improve protection, those parts 
on which the stacks (2, 3) rest are unbroken which 
makes it possible to push the parts together as 
glass (1) is removed from the stack.

Title: A loran-c navigation system
IPC: G01S5/10
Filed: 1988-10-28
Abstract: A Loran-C communications technique and system are 
disclosed involving appropriate encoding of communication 
messages and logical multiplication and inversion of encoded 
signals prior to phase modulation of the Loran-C pulses, 
with novel bit-flip connections for producing complementary 
plus and minus modulation position shifts in the first and 
third and second and fourth, etc., of the Loran-C pulse 
groups, and with perfect balance irrespective of the nature 
of the raw data and irrespective of skywave interference.  
     Also disclosed is a method of 
obviating errors in navigation locking caused by sampling 
reception at the conventional symmetrical pulse modulation 
time intervals in advance of and in delay from the normal 
transmission interval, through rendering the pulse 
modulation asymmetrical to a degree that compensates for 
different cycle amplitudes at sampling points above and 
below the desired sixth zero crossing used for navigation 
position determination.

Title: Method and device for profile extruding, especially tube extruding, a mixture of plant particles with binding agents
IPC: B27N3/28
Filed: 1989-04-20
Abstract: The invention relates to a method for profile extruding or tube extruding a mixture of plant particles, in particular wood particles, with binding agents, the mixture being compressed by the ram of an extruder in a filling space and solidified in the curing channel. The filled material is forced through a filling and pressing space, this space widening in the form of a wedge towards the curing channel, so that the filled material experiences uniform compression in the pressing direction. Due to the uniform compression in the length of each extruded piece produced with the pressing stroke, the pressure acting on the bounding walls of the filling and pressing space will be approximately uniform over the length when the final compression of the extruded part is reached. <IMAGE>
