A control system for a motor vehicle provided with a clutch and a continuously variable transmission. The transmission has a line pressure control valve having ports and a spool for controlling the line pressure of oil supplied to a cylinder of a pulley device to change the transmission ratio. When the clutch is disengaged, the line pressure is set to a minimum value sufficient for tensing a belt ...

Dicaffeoylquinic acid can be separated and obtained as the free acid or salt of the latter from crude vegetable extracts with the aid of gel permeation chromatography on crosslinked modified polysaccharides, in particular on dextrans. If appropriate, the monocaffeoylquinic acids can simultaneously be isolated. To obtain the free acid(s), it is necessary to adjust the aqueous extract to a pH of aro...

Bei einem fahrbaren Röntgendiagnostikgerät (1) soll ein leichtes Einstellen und Ablesen der Anzeigen der Aufnahmeparameter für eine Röntgenaufnahme an mehreren Seiten (7, 8,9) des Röntgendiagnostikgerätes (1) möglich sein. Die Aufgabe wird gelöst, indem das Bedienfeld (4) auf der Oberseite (3) des Steuerkastens (2) verstellbar ist. Der Bedienkomfort wird wesentlich erhöht, ein sicheres Bedienen un...

Biphenyl tetracarboxylic acid esters and derivatives thereof are prepared by the coupling reaction of 4-halogen substituted o-benzenedicarboxylic acid ester, carried out in an aprotic polar solvent in the presence of a pre-prepared triphenylphosphine-nickel chloride or trialkylphosphine-nickel chloride catalyst, zinc powder as the reducing agent, and an alkali metal halide promoting agent. The est...

In a measuring weft feeder for fluid jet looms - of the type comprising a drum (18) held stationary, onto which a rotary reel winds a weft yarn reserve - an electromagnetic unit (EU) is applied to block the weft yarn (20), said unit being of the type comprising a stem (9) movable along its axis, electromagnetically controlled so as to engage the weft yarn (20) laterally with its free end and stop ...

A rotary die cutter (10) includes an anvil roll (18) and at least one die roll (20). One or more sheet metal dies (31) with raised cutting edges (31a) are carried on the die roll (20) to cut patterns in a web of material (W) passing between the die (31) and the anvil roll (18). The die cutter (10) has a pair of rigid side frames (14) spanned by a very rigid spreader (16). While the anvil roll (18)...

Point-bonding and water-jet-softening of a sheet of flash-spun polyethylene plexifilamentary film-fibril strands provide a nonwoven fabric that is particularly suited for dyeing and use in disposable protective garments. Garments made with the nonwoven fabric are comfortable and provide a good protection against particulate matter, such as air-borne asbestos particles.

A disposable article is formed of an alkali-sensitive film or an alkali-disintegratable non-woven material and is adapted to dissolve in an alkali environment, which may be liquid, having a sufficiently high alkali pH value, say 7.5 or more. An example of such an article is the inner, next-to-body, liner of a disposable diaper which can be disposed of in a toilet bowl with contained body waste mat...
