Vinyl compounds of the formula I in which R is H, an alkyl or alkenyl radical having 1 to 15 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or at least monosubstituted by halogen, it also being possible for one or more CH2 groups in these radicals to be replaced, in each case independently of one another, by -O-, -S-, , -CO-, -CO-O-, -O-CO- or -O-CO-O- in such a manner that oxyg...

A gas chromatography system which incorporates a simplified sample injection system in which replaces conventional mechanical injection systems with one based strictly upon thermal trapping of a continuously supplied carrier gas and sample stream. The carrier gas and sample stream pass continuously through the device which incorporates a thermal focusing chamber which communicates with the inlet e...

These compounds correspond to the formula: in which R1 represents H or an alkyl, phenylalkyl, aminoalkyl, optionally esterified carboxyalkyl, cyanoalkyl, carbamoylalkyl, hydroxyalkyl or alkoxyalkyl group; RIV represents an optionally substituted cycloalkyl group or an aromatic group such as an optionally substituted phenyl or heterocycle or RIV and RV together represent the group:

Described are hetero-aryloxy-.beta.-carbolines of the formula (I), in which RA is a triazine-condensed or benzo-condensed heteroaryl entity with 1-2 nitrogen atoms, which may optionally be substituted by halogen, C1-6alkyl, C1-6alkoxy, C1-6alkylthio, trifluoromethyl or SO2-R1, or a 5 or 6membered hetero-aryl entity with 1-2 nitrogen atoms, substituted by halogen, C1-6alkyl, C1-6alkoxy, C1-6alkylth...

Heterocyclic substituted 2-acylamino-5-thiazoles, their preparation and pharmaceutical compositions containing them. A 2-Acylaminothiazole of formula : (I) in which R1 is H, an alkyl or a substituted alkyl; RIV is a cycloalkyl, an aromatic group such as phenyl or a heterocyclic group which are unsubstituted or substituted; RV is a substituted alkyl, a substituted carboxy sueh as an ester or an ami...

In blood examinations, first basic items such as the number of red blood cells, the number of white blood cells and the volume of hemoglobins are measured (primary examination), then, on the basis of the results thereof, further specific additional items are measured such as leukocyte classification and measurement of reticulocytes (secondary examination). In this case, the basic items are measure...

Process for recovering cyanide values from a mill tailings stream remaining after gold and silver have been leached from an ore, by treating the tailings stream containing both ore insolubles and remaining cyanide leachant, without a preliminary filtration, to acidification with an acid to a pH of at least 4, stripping the cyanide values therefrom with a stripping gas in a stripping column such as...

In a low-frequency induction heater comprising a primary side coil having a core and a secondary side conductive hollow cylindrical member surrounding the primary side coil, it is sought to improve the Joule heat generation efficiency and solve problems peculiar to composite materials such as thermal deformation, electrolytic corrosion and difficulty of manufacture by forming the conductive hollow...

In cigarette conveying apparatus cigarettes are conveyed along a path so that they are intercepted in sequence by beams directed at different portions of the path to produce a complete circumferential row of perforations on each cigarette after it has traversed the path. An incident laser beam (14) is time-shared to produce pulses for making perforations by mutually inclined rotatable discs (20, 2...

The compressed time telegram (16) is led across an interface (10) to the time clock or time switch. The evaluation unit (4) has coding units (5, 8) assigned to it. The transmission of the compressed time telegram (16) is carried out by means of a two or three wire interface. The transmission of the compressed time telegram follows by modulation and demodulation via the mains or radio. ADVANTAGE - ...

A multi-step switch includes a resilient or resiliently mounted push button. In a first stage of the pressed-in state, the push button presses a contact surface against an at least partially resiliently constructed printed circuit board, which, on the upper side thereof, is provided with conductors. In a second stage of the pressed-in state of the switch, the push button and, in turn, the printed ...

In flat, porous bags contg. a single dose of detergent, the detergent is dissolved and distributed in the drum of an automatic washing machine. Apart from the detergent, the container also holds a body of an appropriate thickness. The body holds the walls of the bag apart and promotes the distribution and dissolution of the detergent. The body has a complete freedom of movement inside the bag, res...

The seal includes a rotationally rigid bellows (6) whose inner edge (4) is axially fixed on the shaft and whose outer edge (8) is fixedly and sealingly connected to the housing (3). The shaft (1) has a centring seat (9) for the outer edge (8) of the bellows and thus forms a tool with which the outer edge (8) can be fixed on the housing (3) when the shaft (1) is installed in the housing. The centri...

The first main flexible but rotationally secured bellows (14) are mounted between the wall (2) and shaft (1). The second backup bellows (15) connects the outer edge (17) to the inner edge (20) of the first bellows (14). In order to avoid inflation of the hollow cavity and thus to increase the service life at least a cavity (23) between the two bellows (14,15) contains a viscous fluid with low heat...
