Filed: 1982-09-30
Abstract: Mixtures which are used for the production of polyurethane foam and which contain amines having primary or secondary aliphatic hydroxyl groups, and also customary quantities of trichlorotrifluoroethane and/or trichlorofluoromethane as a blowing agent, can be stabilized against the premature reaction of the components by adding 0.05 to 5% by weight of 2,4-diphenyl-4-methylpentene in which the ratio of the 2,4-diphenyl-4-methyl-1-pentene isomer to the 2,4-diphenyl-4-methyl-2-pentene isomer is 1:1 to 9:1, the percentages relating to the chlorofluoroalkane. In particular, these mixtures can be stabilized by adding 0.1 to 5% by weight of a mixture consisting of 45 to 89% by weight of 2,4-diphenyl-4-methyl-1-pentene, 10 to 45% by weight of 2,4-diphenyl-4-methyl-2-pentene and 1 to 20% by weight of 1,1,3-trimethyl-3-phenylindane.

Abstract: Bei einem Verfahren zur Ansteuerung einer multiplexier­
baren, bistabilen Flüssigkristallanzeige wird ene erste 
Betriebsspannung (V₁), die grösser ist als eine erste Grenz­
Spannung (V g1 ) an die ausgewählten Anzeige-Elemente 
angelegt und eine zweite Betriebsspannung (V₂), die kleiner

Patent EP-0121261-A3 (EP)
IPC: G01N15/14
Filed: 1984-03-31
Abstract: A method for distinguishing multiple subpopulations of 
particles in a sample comprises passing particles in a sample, 
substantially one at a time, through an area of light detected at 
the particles. The volume of each particle is determined, pre­
ferably, as it passes through the area of focused light incident 
to the particles. Light scattered by each particle is detected as 
the particle passes through the area of light, over a wide angle 
relative to the direction of incident light. This method includes 
distinguishing different subpopulations of the particles by 
associating the determined volume of each particle with its 
detected light scatter. The simultaneous detection of particle 
volume, fluorescence and light scatter is determined in a 
single pass through flow cytometry equipment.  
     An apparatus for carrying out the abovedescribed 
method is also within the purview of the present invention.

IPC: B23K9/127
Filed: 1984-12-07
Abstract: A relative weaving motion of a welding torch (12) relative 
to a weld line (M) is given to a welding torch, by way of com­
posing a weld main path vector (v) for a relative movement of 
the weld torch along the weld line and a swing vector (W₁, W₂) 
for a relative movement of the weld torch. And by detecting the 
amount of electricity corresponding to an arc of the weld torch, 
the amount of correction is calculated basing upon the devia­
tion between the detected amount and a predetermined refer­
ence amount. The direction of the amount of correction is de­
termined basing upon the swing vector. The relative movement 
of the weld torch relative to the weld line is performed by a vec­
tor composed of the weld main path vector, the swing vector, 
and the correction vector. In other words, the present inven­
tion features in that the direction of the amount of correction is 
definitely determined basing upon the swing vector.

Patent EP-0174263-A3 (EP)
IPC: B29C71/02
Filed: 1985-09-03
Abstract: Polyester articles are often heat set at an elevated 
temperature under a mechanical constraint which prevents 
their shrinkage during the heat setting process. Such a heat 
setting process provides the polyester article with improved 
dimensional stability. However, the heat set article will still 
shrink when exposed to high service temperatures even 
though the shrinkage is less than that which occurs in 
non-heat set articles.  
     The use of the process of this invention results in 
polyester articles with greatly improved dimensional stabil­
ity. It entails heating an over-sized heat set polyester article 
in an unconstrained manner to a temperature which is 
greater than the expected service temperature of the article 
and no more than the heat setting temperature used for heat 
setting the over-sized article for a time sufficient to produce a 
dimensionally stable article of the desired size.

Title: Method for producing ammonium metatungstate from ammonium paratungstate
IPC: C01G41/00
Filed: 1986-04-25
Abstract: A method is disclosed for producing ammonium metatungstate from ammonium paratungstate. The method involves first roasting the ammonium paratungstate at from about 275 DEG  C. to about 300 DEG  C. for from about 10 hours to about 20 hours to remove some ammonia and some water. The roasted ammonium paratungstate is then added to dilute solution of an ammonium metatungstate which is at a pH of from about 3.6 to about 4.2, the rate of addition being such that a slurry is produced having a pH of from about 3.6 to about 4.2. The pH of the resulting slurry is then adjusted to stabilize it at from about 3.6 to about 4.2 followed by evaporation to form a relatively concentrated solution of ammonium metatungstate which is then separated from any insolubles. Ammonium metatungstate is then crystallized from the relatively concentrated ammonium metatungstate solution.

Abstract: Ein steckbares Relais ist mit im Gehäuse angeordneten Kontakten

Um einen einfachen und kostengünstigen Aufbau des Relais zu 
erreichen, ist vorgesehen, daß das Relais auf die Leiterplatte erst 
nach Abschluß aller Lötvorgänge und der nachgeschalteten 
Bearbeitungsvorgänge auf der Leiterplatte montiert wird. Das Relais

Kontakte im Relais als Buchsen ausgebildet sind, in welche 
zugeordnete Lötstifte der Leiterplatte oder eines Sockels

Title: Adjustable double-acting damper
IPC: F16F9/44
Filed: 1986-05-22
Abstract: A dashpot damper for acting between two objects subject to move toward and away from one another includes a housing (12) including an elongated cavity (66), a piston mounted within the housing cavity for reciprocating movement therealong and dividing the cavity into two variable-volume, hydraulic fluid chambers (67,69), and a network of passages permitting hydraulic fluid to flow between the two variable-volume chambers as the housing and piston move relative to one another in response to relative movements between the two objects. The damper utilizes unitary flow control cartridge (16, 17) mounted within the housing and defining a passageway (186) through which hydraulic fluid is forced to flow when passing between the two variable-volume chambers (67, 69). The flow control cartridge (172) also restricting the flow of hydraulic fluid in one direction through the passageway (186) and for permitting substantially unrestricted flow of hydraulic fluid in the other direction through the passage. By controlling the flow of hydraulic fluid through the passageway (186) in said one direction, the damping effect of the damper is controlled. The flow control cartridge (16, 17) can be constructed so as to provide either an adjustable or fixed restriction to the hydraulic fluid flow in said one direction.
