The invention concerns a test system for carrying out blood sugar tests with a diagnostic tape cassette which comprises a windable analytical test tape for detecting an analyte and a cassette housing accommodating the test tape, and a test device which has a device housing for inserting and removing the tape cassette and a measuring unit for detecting the analyte on the test tape. According to the invention it is proposed that the tape cassette can be detachably fastened by positioning elements on a platform mounted in the device housing and that the measuring unit is rigidly attached on the platform or can be engaged therewith.

A protective container (10) wherein a flexible wall (14) is connected to a base (20) and a cap (26). Deflection of the flexible wall (14) buffers the contents of the container (10) against impacts and is limited by the rate of air flow between one end of the flexible wall (14) and a cap (26) that closes container (10).

A clamping element for the transport of a substrate in a predefined transport direction comprises a first and a second leg with a first and second clamping jaw for clamping a substrate. Each of the two clamping jaws has a clamping plate which is movable in transport direction relative to the corresponding leg. A sensor measures the deflection of the first clamping plate relative to the first leg. As soon as the measured deflection exceeds a predefined threshold value, the clamping element is opened.

In an adjusting device for a seat in a motor vehicle, a sliding seat guiding mechanism moves the seat in a generally horizontal direction. The guide mechanism includes an upper part secured to the seat and a support member secured to the floor of the vehicle. A rack is attached to the upper part and is driven by a pinion mounted on the support member for moving the seat in the generally horizontal direction. The rack is adjustably mounted on the upper part to permit limited movement of the rack in the generally vertical direction disposed transversely of the generally horizontal direction of movement of the seat so that proper engagement of the rack and the pinion is assured.

The window in the door of an automotive vehicle is raised and lowered by means of an externally threaded, longitudinally moving cable. The drive arrangement for the cable includes a shell having first and second shell portions of which at least one is formed with an aperture. A pinion is rotatably secured between the shell portions and journaled in the aperture of apertures. A first group of fastening devices fastens the first shell portion to the second shell portion in a predetermined position, but may also fasten the shell portions to one another in each of a plurality of other positions angularly offset about the axis of pinion rotation from the predetermined position. The shell portions define therebetween respective passages through the shell in the several positions of the first shell portion, the passages being approximately tangential relative to the pinion and angularly offset from each other about the axis of the pinion. Each passage is associated with one of the positions of the first shell portion, and the externally threaded cable is movably received in the passage associated with the predetermined position of the first shell portion, but dimensioned for longitudinal movement in each of the other passages. A second group of fastening devices permits the second shell portion to be fastened to the vehicle door.

Peracylated aliphatic polyamines are useful as activators for inorganic peroxo compounds, i.e., they set free the available oxygen of the peroxo compounds in aqueous solutions at temperatures below 80.degree.C and are thus useful as additives to detergents especially inasmuch as they are compatible with usual detergent brighteners.
摘要:
A container comprising a first tubular body defining a fastening structure and a seam that extends across an end wall, and at least one depressed channel formed in the end wall. The seam is located in the depressed channel so as to separate the seam from the contents of the container. In an embodiment, there is a second tubular body secured to the first tubular body by a fastening structure that cooperates with the fastening structure of the first tubular body. The second tubular body also has a seam that extends across a wall that is located in a depressed channel so as to separate the seam from the contents of the container.

Process for the preparation of 4,4'-dinitrodiphenylamine which comprises reacting 1 mole of 4-halonitrobenzene with about 1 to about 3 moles of an alkali metal cyanate in the presence of about 0.5 to about 5 moles of water in dimethylsulfoxide at temperatures of about 150.degree. to about 170.degree. C.

A process for the preparation of 3-(acyl)amino-4-alkoxy-phenyl-.beta.-hydroxyethyl-sulfone (sulfates) of the formula (1) ##STR1## in which R.sub.1 is alkyl having 1-4 carbon atoms and R.sub.2 is hydrogen or one of the groupings ##STR2## with the proviso that n=1 if R.sub.2 =H and n=0 if R.sub.2 =acyl, by converting 2-alkoxyacylanilines of the formula (2) ##STR3## in which R.sub.1 and R.sub.2 have the meanings given, in a known manner to the corresponding sulfochlorides substituted in the p-position relative to the alkoxy group, reducing the sulfochlorides with an alkali metal sulfite or ammonium sulfite in an aqueous medium at pH 7.0-8.5 and at -5 to +40.degree. C. to give the corresponding sulfinates, alkoxylating the latter with ethylene oxide in an aqueous medium at pH 6.0-8.5 and 40.degree.-80.degree. C. to give the 3-acylamino-4-alkoxyphenyl-.beta.-hydroxyethyl-sulfones of the formula (1) (with R.sub.2 =acyl and n=0) and, if appropriate, esterifying the latter, with deacylation, with concentrated sulfuric acid at 70.degree.-150.degree. C. to give the compounds of the said formula (1) (with R.sub.2 H and n=1).
