Title: Process for selectively removing sodium cations from a solution containing sodium and ammonium cations
IPC: B01J39/04
Filed: 1986-05-16
Abstract: A process is provided for selectively removing sodium ions from a solution containing sodium and ammonium ions using a polysulfonated aromatic cation exchange resin. The polysulfonated resin exhibits enhanced selectivity for sodium ions over ammonium ions when compared with conventional, monosulfonated cation exchange resin. This enhanced selectivity results in a lower concentration of sodium ion leakage and longer bed life to critical leakage, compared with conventional, monosulfonated resins.

Patent EP-0244640-A3 (EP)
IPC: G02B21/08
Filed: 1987-04-03
Abstract: A microscope using deconvolution is described, in which the light distribution in the double cone formed by the light is modulated. The modulation is performed in the spatial domain, which distinguishes the system from modulation in the temporal domain such as is known in telecommunications engineering. Optical radiation is modulated by inserting into one of the planes of the microscope a modulating pattern in which the radiation source is sharply imaged. The modulated light traverses the further elements of the beam path and finally impinges on a television camera. The output signal of the television camera is fed to a computer. As an example, 64 sequential object positions are recorded in 64 different focal planes and transmitted as digitised images to the computer, where they are stored and deconvoluted, use being made of an algorithm which takes account of the presence and absence of light in the various regions of the double cone. In order to adapt the algorithm to the modulation pattern employed, a matrix of data is recorded which reproduces the three- dimensional pulsed response of the microscope by means of the modulation pattern. This is performed by Fourier transformation or any other convolution algorithm. This data matrix takes account of the properties of the optics of the microscope, and is transformed into improved images by a convolution algorithm. These images have a superior 3D-resolution, which cannot be achieved at the same speed using other methods. <IMAGE>

IPC: B01D3/06
Filed: 1987-08-14
Abstract: Verfahren zur Erzeugung niedriger absoluter Drücke für 
die Behandlung von Ölen und Fetten, bei welchem Öl- und Fett­
anteile, Fettsäuren und/oder Talg sowie Wasserdampf enthal­
tender Prozessabdampf durch Mischkondensation mit im wesent­
lichen im Kreislauf geführter Kühlflüssigkeit niedergeschlagen 
und vor der Wiederverwendung in der Mischkondensation zurück­
gekühlt wird. Die Kühlflüssigkeit wird durch partielle Ver­
dampfung (flash - Verdampfung) zurückgekühlt. Die Kühlflüssig­
keit selbst wird letzten Endes durch Kondensation des Prozess­
abdampfes erzeugt und besteht im wesentlichen aus Wasser und 
auch aus Ölen, Fetten, Fettsäuren und/oder Talgen, die in dem 
Wasser emulgiert und/oder suspendiert sind. Durch die partielle 
Verdampfung der Kühlflüssigkeit wird die Behinderung der Wärme­
abfuhr durch kristallisierte Fettschichten auf den Flächen der 
üblicherweise verwendeten Wärmeübertrager vermieden. Gleich­
zeitig wird aus der partiellen Verdampfung ein nahezu voll­
ständig von Ölen und Fetten freies Kondensat als Abwasser ge­
wonnen, das die Umwelt nicht belastet. Außerdem ist es möglich, 
die Abscheidung der Öle, Fette, Fettsäuren und/oder Talge erst 
nach der Rückkühlung durchzuführen. Die Kondensation des 
Dampfes aus der partiellen Verdampfung wird bei Temperaturen 
über 0° C in ununterbrochener Betriebsweise durchgeführt. Wird 
das Verfahren bei Temperaturen dicht über 0° C angewendet, so 
 
 
ergeben sich Vorteile in der guten Wirkung der Abscheidung der 
Öle und Fette und auch darin, daß das erhaltene Kondensat 
besonders niedrige Gehalte an Ölbestandteilen aufweist.

Patent EP-0276868-A3 (EP)
IPC: H04L27/156
Filed: 1988-01-29
Abstract: The demodulation circuit includes a Schmitt trigger circuit(2), 
first and second monostable multivibrators (31, 32), a quartz 
oscillator (5), first and second low-pass filters (4, 6), and a 
comparator (7). The Schmitt trigger circuit (2) converts a 
modulated signal modulated by data into a pulse signal. The first 
monostable multivibrator (31) converts an output from the Schmitt 
trigger circuit (2) into a PPM signal. The quartz oscillator (5) 
oscillates at the same frequency as the center frequency of the 
modulated signal. The second monostable multivibrator (32) is 
formed on the same chip as the first monostable multivibrator (31) 
and responsive to an output signal from the quartz oscillator (5). 
The second monostable multivibrator (32) generates a signal 
comprising a pulse train having the same pulse width as that of 
the PPM signal output from the first monostable multivibrator (31) 
and a constant pulse separation. The first low-pass filter (4) 
receives an output from the first monostable multivibrator (31). 
The second low-pass filter (6) receives an output from the second 
monostable multivibrator (32). The comparator (7) compares an 
output signal from the first low-pass filter (4) with an output 
signal from the second low-pass filter (6) as a threshold level, 
and obtains modulation data.

Title: Process for microinjection into cells, possibly for suction out of isolated cells or entire cells out of cell cultures
IPC: C12N15/89
Filed: 1988-05-21
Abstract: In this computer-assisted system, a pointer which can be moved in the image on the monitor (10) is superimposed on the television image of the cell culture and is positioned by the operator on the cells to be injected by relative movement of the pointer/image in the television image. The coordinates of the cells indicated in this way are stored by the computer (11) which subsequently automatically moves the capillary tip to, and inserts it into, the selected cells. In an advantageous embodiment, the computer makes the insertion movement parallel to the long axis of the capillary by a superimposed movement (x) of the microscope stage and of the drive for adjusting the height (z) of the capillary (4) on the micromanipulator (3).
