Patent EP-0337338-A3 (EP)
Title: Method for displaying intervisibility data
IPC: G06T15/20
Filed: 1989-04-08
Abstract: A method for presenting intervisibility data relative to an 
observation point (O). A data base of terrain altitudes (Z) 
is stored in a computer memory. The data base comprises terrain 
altitudes (Z) at a grid of points in a selected terrestrial 
area encompassing the observation point (O). Visible height 
from the observation point (O) at the grid points (J, I) are 
derived from the data base with a computer by performing a 
number of steps grid point (J, I) by grid point (J, I+1) in 
succession in an order moving away from the observation point 
(O). The first step is to determine a projected height at the 
grid point (J, I) from the visible heights between the obser­
vation point (O) and the grid point (J, I). The second step 
is to compare the projected height (ZP) with the terrain 
altitude (Z) at the grid point (J, I). The third step is to 
select as the visible height at the grid point (J, I) the 
larger of the compared terrain altitude (Z) and the projected 
height (ZP). A number representative of the visible height at 
each grid point (J, I) as so derived with a computer is stored 
in the computer memory. The computer memory is coupled to a 
visual display device to present the stored representations 
of the visible height in spatial relationship coordinated 
with the spatial relationship of the grid points (J, I) of 
the terrestrial area. The visible height data is derived by 
use of the similar triangles theorem, and interpolation of 
previously calculated visible heights.

Title: Closure with improved pull tab
IPC: B65D75/64
Filed: 1989-08-28
Abstract: This relates to the construction of a pull 
tab integrally formed on a closure which is bonded to a 
container by way of a rupturable bond. Instead of 
utilizing the conventional pull tab which is normally 
integrally connected to the closure, the pull tab has 
been modified so as to provide two lines of bond 
rupturing forces as opposed to the prior art original 
single line with the two lines of bond rupturing forces 
having a tendency to spread in opposite directions 
and thereby greatly reducing the force required to 
initial a rupture of the bond between the closure and 
the container. Numerous different types of notches, 
openings and the like are provided to provide for the 
separate lines of bond rupturing forces. These 
notches, openings and the like also function to limit 
stray electric current induced into an intermediate 
metal layer of the closure and pull tab flowing 
into the pull tab, thereby reducing the power 
requirement for heating the closure to a bonding 
temperature.

Abstract: A cellular radio system in which a base station (BS1) 
establishing two way communication with a mobile (10) requests base 
stations (BS2 to BS7) of a subset of adjacent cells to reserve a

Title: Double tuned circuit for distrubuted lumped capacitance observe coils
IPC: G01R33/36
Filed: 1989-03-17
Abstract: A double tuned circuit for NMR appartus normally has a single 
inductor common to the two resonant circuit portions.  
     In the present case the inductor is split to form two generally 
semi-cylindrical members (40,42), each member being H-shaped, with 
the cross piece of the H acting as a generator of the cylinder and 
the tips of the upright portions of the H lying adjacent the 
corresponding tips of the other member, and connected by chip 
capacitors (44-47).  
     Capacitors and inductors connect portions of the H to ground and to 
two sources of RF energy of different frequency (64, 66), and a bridge 
capacitor (69) is provided between the two input circuit portions 
from the sources.

Title: Automatic determination of coordinates of the operating path of an adhesive-applying nozzle in an adhesive applicator for a shoe machine
IPC: G01B11/03
Filed: 1989-04-03
Abstract: The supports (9; 35) by which adhesive-applying 
nozzles (6) are supported in a shoe machine, e.g. a 
cement lasting machine, for tracking movement along 
opposite portions of a shoe bottom (5) are provided with 
mountings (34) by each of which either such a nozzle (6) 
or a sensing head (20) can be supported. In the latter 
case, as the sensing heads (20) are moved in the 
X-direction under the control of a stepping motor (18), 
the heads sense the edge of the insole (which may be 
provided with a black line (23, 24)) and by feedback 
signals are caused to follow it, thereby determining the 
Y-axis movement corresponding to the X-axis movement 
necessary to guide the nozzle in the subsequent 
adhesive-applying operation. The Y-axis movement is 
stored at memory locations for which the Y-direction 
movement values constituted the address. When, therefore, 
subsequently in an adhesive-applying operation, the 
nozzles are caused to track along the X-axis, the Y-axis 
information is accessed and the nozzles are moved in the 
Y-coordinate axis direction accordingly.

IPC: A61N1/40
Filed: 1989-05-02
Abstract: A system (10) is disclosed for facilitating the healing of traumatized tissue and broken or fractured bone. The system (10) establishes an electric field between a pair of electrodes (14) positioned on opposite sides of the patient site (12), resulting in the production of an alternating current having the desired frequency and amplitude characteristics in the tissue or bone. Specifically, the system (10) includes a resonator (32) formed by an inductor (36) coupled in series with the resistor (R1) and capacitor (C1) of an equivalent circuit (34) representing the patient site (12), the electrodes (14) , and any gaps (30) therebetween. This resonator (32) also includes a capacitor (C2) designed to prevent spurious, high-frequency oscillations. The resonator (32) is operated by a free-running oscillator (16), which maintains the operationof the resonator (32) at its resonant frequency. The oscillator (16) includes a forward network (38), having a CMOS inverter (42), and a feedback network (40), including an open-loop operational amplifier (52), and provides a simple, stable, and efficient form of operation free from spurious, high-frequency oscillations.

Title: Improved affinity supports for hemoperfusion
IPC: B01J20/281
Filed: 1989-11-08
Abstract: A method of coating chromatographic particu­
late supports to provide a biocompatible outer layer of 
synthetic membrane-type film which prevents the release 
of fines but permits the adsorption of components to an 
affinity ligand is described. The matrix is provided 
with a membrane-type coating, which prevents leaching of 
fines, with a pore size of at least 20 angstroms. The 
coating is applied to a solid particulate under condi­
tions where an integral membrane coat will be formed. 
It may also be necessary to control the size and number 
of pores of the membranes by treating a suspension of 
the solid support in a solvent which contains 0.1-1% of 
the support weight of a biocompatible polymer along with 
0.5-5% of the weight of said polymer of a dissolved com­
patible pore-controlling component. The solvent is then 
removed from the suspension and the membrane-coated 
material used in extracorporeal treatment of body fluids 
or in other chomatographic techniques. The coating 
process can be conducted before or after the particulate 
support is functionalized and/or derivatized.

IPC: C01G49/06
Filed: 1990-05-26
Abstract: A continuous multistage process for separating a 
partially water soluble organic component from a slurry 
containing an insoluble solid, a partially water soluble organic 
component and optionally water. In this process, the slurry (5) is 
continuously fed to a tower or column (1) equipped with a suitable 
vapor/liquid contact device (2). Energy (12) is applied at a point below 
the vapor/liquid contact device. Vapors containing the partially 
soluble organic component exit the tower or column overhead and 
the inorganic solid (11) is recovered at the bottom of the tower or 
column. This application of distillation technology to slurries 
is particularly advantageous in that a more efficient separation 
of that solid material from the partially soluble organic 
component is obtained. The improved separation efficiency can be 
utilized to either lower separation cost and/or to affect a more 
complete separation in order to obtain a solid material with a 
lower residual amount of the organic component.
