Patent EP-0047579-A3 (EP)
Title: Solder removing device
IPC: B23K1/00
Filed: 1981-07-27
Abstract: 57 A solder removing device comprises fibres of temperature-resistant non-metallic material, such as a synthetic polymeric material, for example FEP or PTFE, which are coated with a metal rendering them more receptive to solder flux. The metallised fibres are coated with solder flux rendering them more capable of wetting with molten solder, interstices between the fibres serving to absorb molten solder by capillary attraction.

Title: Polyamines, process for producing polyamines and their use in the production of polyurethanes
IPC: C08G18/10
Filed: 1983-06-13
Abstract: Polyamines containing aromatically bound primary amino groups having an NH2-content of from 0.19 to 20.3 wt % are produced by a single stage process. A compound containing aromatically bound NCO-groups and having an isocyanate content of from 0.5 to 40 wt % is hydrolyzed with an excess of water in the presence of a water-miscible polar solvent and optionally a catalyst. The hydrolysis is carried out at a temperature of from -10 DEG  to 150 DEG  C. in a manner such that the reaction mixture is substantially homogeneous. The water-miscible polar solvent generally has a boiling point of from 56 DEG  to 250 DEG  C. and a dielectric constant of at least 10. This polar solvent is used in a quantity of at least 5 parts solvent for every 100 parts of isocyanate. Tertiary amines are the preferred catalysts. These polyamines are particularly useful in the production of polyurethanes.

Filed: 1984-06-13
Abstract: A thermodynamic process having an efficiency close to that of the ideal Carnot cycle. The process fluid is a combination of Dowtherm A and water and undergoes constant pressure transformations to absorb heat from a heat source and to transfer heat to a heat sink, and also undergoes constant temperature expansion and constant temperature pressurization.

Patent EP-0146764-A3 (EP)
IPC: H01M4/06
Filed: 1984-11-15
Abstract: An improvement is provided for the manufacture of 
perhalogenated polymer, e.g., PTFE, bonded electrodes.  
     The formulation comprises a mixture of an active 
material is carbon monofluoride otherwise known as 
fluorinated graphite or fluorinated carbon or CF x  or (C₂F) n ); a 
conductive carbon additive, such as acetylene black or 
graphite; and polytetrafluoroethylene (PTFE).  
     The process comprises high shear mixing to cause the 
PTFE to fibrillate. The mixture is then wet with a non-­
polymeric pore-former to make the mixture more pliable and 
to create micropores in the electrode when the solution is 
removed by evaporation. The wet mixture is then sequential­
ly suitably formed into a, e.g., extruded, or calendered or 
pressed to flatten the mixture to a thin sheet and rolled up 
and folded and pressed out again until a uniform sheet is 
obtained and the like.  
     The resiilting product affords a sheet which is relatively 
flexible, and stronger and allows a lower PTFE loading than 
has been obtained with other electrode sheet materials 
formed with fibrillatable polymers. The higher the PTFE 
content, the higher the voltage losses for the electrode.

Abstract: An endless sealing strip (48) has a base portion (52) 
which is held in a mounting channel inside the housing of a 
seed meter, and a lip (54) springing from the base portion. The 
lip bears against one face of a seed disk to define, with the disk 
and the housing, a vacuum chamber which applies suction 
through holes in the disk to pick up seeds from a seed cham­
ber on the opposite side of the disk and carry them to a dis­
charge sector where they drop off the disk and down a planting 
chute. The major part (84) of the seal lies on a circle outside 
the path of the holes. In the discharge sector the seal has a re­
entrant portion (92) which is set inside the path of the holes so 
that suction is not applied over the discharge sector, in order 
that the seeds may drop off the disk.

Filed: 1986-03-24
Abstract: Mechanical stability and coating characteristics of 
structurally cation-active, film-forming latex, especially useful 
in electrodeposition coatings can be improved by the addition of 
small stabilizing amount of linear cationic amine-modified epoxy 
resin having tertiary amine functionality and base number in the 
range of 30-500 and/or glycol mono-substitut  ed ether alcohols. 
"Stability" is defined by the absences of agglomerated latex 
particles as shown by disc centrifuge photosedimentometer traces 
after subjecting the latex to 30 minutes of mechanical shear using 
a Hamilton Beach mixer. Such stabilized latex remains substanti­
ally non-agglomerated even after being subjected to pumping and 
shear. Without the stabilizer, agglomeration of the latex occurs.
