Title: Separation of microbial polysaccharides as amine adducts, and their use
IPC: C08B37/00
Filed: 1983-08-11
Abstract: Microbial polysaccharides can be quantitatively precipitated from their aqueous solutions, in particular directly from the fermentation solutions, in an acidic medium in the form of an adduct with a tertiary amine which has a long-chain alkyl radical. It is advantageous to add the amine to the polysaccharide solution and then to carry out the precipitation, in particular by adding the dispersion obtained to an acidic coagulation bath. The adducts are suitable for use as thickeners and for preparing the free polysaccharides.

Abstract: Die Erfindung bezieht sich auf ein Verfahren zur Herstel­
lung von Halbleiterchip-Filmträgern, die auf der einen Seite 
mit einer Kupferkaschierung versehen und im Kunstoffträ­
gerbereich eine Aussparung für Halbleiterbauelemente 
enthalten. Bei derartigen Filmträgern muß zur Vermeidung 
von Metallabscheidungen auf der der Struktur abgewandten 
Seite das Folienband auf der Oberfläche einer entsprechen­
den Entwicklerlösung schwimmend von unten entwickelt 
werden. Auch alle übrigen Verfahrensschritte können nur 
einseitig vorgenommen werden, was zu einer erheblichen 
Verfahrenserschwernis führt. Zur Vereinfachung sieht die 
Erfindung vor, je zwei Filme über ein Bindemittel zu einem 
Laminat zusammenzuführen, dann zu entwickeln und 
anschließend beide Filme wieder zu trennen.

Abstract: Um sowohl eine konzentrierte, möglichst wenig gelöstes 
Salz enthaltende Natronlauge als auch ein Festsalz mit 
möglichst geringem Gehalt an NaOH zu erhalten, werden die 
beim Eindampfen und Abkühlen der Natronlauge aus der 
NaCl-Elektrolyse anfallenden Mehrfachsalze zersetzt. Dazu 
wird im Seitenstrom zum Lauge-Hauptstrom der Eindamp 
fanlage der entnommene Salzbrei zunächst eingedickt, und 
ein Teil der Natronlauge mit großem NaOH-Gehalt wird 
durch Lauge mit geringerem NaOH-Gehalt ersetzt. Die 
Mehrfachsalze werden in einem ebenfalls im Seitenstrom 
liegenden Zersetzer mittels Natronlauge mit weniger als 30 
% NaOH-Gehalt zersetzt. Bei diesem Verfahren wird weder 
bereits auskristallisiertes Salz aufgelöst noch die Salzbela­
stung im Haupt-Laugestrom erhöht. Der Verlust an NaOH 
wird gegenüber den bisher üblichen Verfahren merklich 
herabgesetzt

control the actuation of the driven elements, and to which 
the latter are connected preferably by means of flexible 
pipes. The control set is formed by a group of pulsators-­
commutators, the actuation of which determines the opera­

which are to be driven, this group being fed through a main 
switch and the set of pulsators-commutators provided on the 
control board of the vehicle in a place easily accessible to the 
user. The set of driven elements is formed a unit of cylinders,

Patent EP-0194476-A3 (EP)
IPC: G01N29/28
Filed: 1986-02-18
Abstract: Method and apparatus for ultrasonically inspecting 
coextruded plastic sheet as it is produced.  
     The apparatus comprises means for supporting a sec­
tion of sheet in position to be inspected, and means for 
supporting transducer means in contact with the surface of 
said sheet. The transducer means comprises at least one 
housing supporting an ultrasonic transducer and defining a 
chamber between the face of the transducer and the surface 
of the sheet. The chamber is filled with an interfacing fluid so 
that ultrasonic pulses from the transducer will pass through 
the fluid into the sheet to be reflected from any interface 
therein. The transducer means and interfacing fluid are 
moved across the surface of the sheet to permit inspection of 
the entire sheet. Thus, it is unnecessary to submerge the 
sheet in a vat of interfacing liquid or to bend or otherwise 
deform, and possibly damage, the sheet as is done in current 
systems. The apparatus further includes means within said 
chamber for directing interfacing fluid substantially trans­
versely across the face of the transducer for washing away 
any air bubbles that may form in the interfacing fluid 
between the transducer and the surface, together with 
means for maintaining a substantially continuous flow of the 
fluid thereacross.  
     The ultrasonic pulse echoes received from the sheet are 
analyzed to provide an indication of the presence and 
thickness of layers therein.

Title: Apparatus for treating liquid
IPC: A23C3/037
Filed: 1980-10-07
Abstract: A method for maintaining a stable liquid level in a pressurized chamber is described. According to this method a liquid to be treated is heated by direct contact with steam with the consequential condensate being mixed with the treated liquid and removed from said chamber. The following steps are provided: establishing a desired flow rate of liquid to be treated into said chamber, supplying saturated steam to said chamber to heat said liquid by contact heating to condense the steam, collecting the treated liquid along with the condensed water from the steam to maintain a predetermined liquid level in said chamber, varying the rate of steam supply and pressure to maintain the predetermined treatment temperature of the liquid as it is removed from the chamber, and selecting and using for each liquid to be treated a fixed flow area device (276) to control the rate of removal of said treated liquid from said chamber to maintain said predetermined liquid level irrespective of variation of control and said steam supply. An advantageous application field of this method is a process for heating fluids to a relatively high temperature, such as sterilization of UHT temperature, in which the liquid is heated by direct contact with steam while it is held in the form of a very thin, free-falling or a continuous falling stream.

Title: Process for printing a material
IPC: D06P5/28
Filed: 1986-08-25
Abstract: The invention relates to a process for printing a material. 
<??>More specifically, it is concerned with a process by which a material is decorated with a multicoloured design consisting of an association of primary elementary forms, such as any geometrical forms, figures or letters, each having a primary colour, the multicoloured design being produced beforehand on a provisional support from inks capable of being transferred onto the material by heat and pressure. 
<??>According to the invention, a basic set of coloured sheets is formed by stacking one or more sheets covered on one flat face with sublimable ink, the set comprising at least one sheet of each primary colour of the final multicoloured design, the contours of the elementary forms of the decorative design are formed in relation to the outer contour of the material to be decorated by simultaneous cutting in each sheet of the set, all the sheets then each identically possessing precut zones corresponding to the elementary forms of the final design, the multicoloured decorative design is composed on a provisional support by a superposition and/or juxtaposition of the precut primary elementary forms, the primary elementary forms being taken from the sheet of corresponding primary colour, and the multicoloured design thus composed is transferred from the provisional support onto the material to be decorated, the provisional support and material being kept in intimate contact by pressure, and heating being carried out in such a way that there is a sublimation of the inks and an identified diffusion of the inks in the material.
