Abstract: Thioalkane .alpha.,.beta.-diketones have interesting organoleptic properties and are therefore suitable as aroma substances.

Abstract: Ketals, preferably glycerol ketals such as, for example, 1-menthone glycerol ketal or 3,3,5-trimethylcyclohexanone glycerol ketal, have a physiological cooling effect and are therefore suitable as active compounds in compositions which are intended to cause a sensation of freshness on human skin or mucous membrane.

Abstract: Dimethylfuryl-dihydro-1,3,5-dithiazines are useful flavorings having low taste threshold values. They impart a coffee or mocha taste, in particular to drinks, confectionery and bakery products.

Abstract: The invention relates to new thio-alkanones of the formula ##STR1## in which X represents an oxygen or sulphur atom,R.sub.1 represents hydrogen or a C.sub.1 -C.sub.2 -alkyl group and the broken lines represent a single bond or no bond,to a process for their preparation and their use as flavorings.

Abstract: New hemimercaptals of the formula ##STR1## in which X represents an oxygen or sulphur atom, a process for their preparation and their use as flavorings have been found.

Abstract: The invention relates to the use of oct-2-en-4-ol as a flavor, and to flavoring compositions containing this compound.

Abstract: A perfumed or edible composition comprising an appropriate carrier and an amount of 5-methyl-hept-2-en-4-one effective to impart its fragrance or flavor to the composition. It imparts a fragrance and flavor reminiscent of hazelnut.

Abstract: Unsymmetrical dihydrodithiazines of the formula ##STR1## in which one of the substituents R.sub.1 and R.sub.2 represent a C.sub.3 -C.sub.5 -alkyl group while the other is a methyl group and R.sub.3 represents a hydrogen atom, or R.sub.1 represents a methyl group and R.sub.2 and R.sub.3 together form a C.sub.3 -C.sub.4 -alkylene radical, a process for their preparation and their use as fragrances and flavorings.

Abstract: Spinning machine in which the upper rollers of the drafting units are arranged at pressure arm assemblies, whereby each pressure arm assembly has a main arm and an operating lever which is positionally arranged above the main arm and radially movable. To each work location of the machine are assigned signal lights for indicating disruptions at the work location. For optimum visibility from distant locations, the indicator lights are provided at the operating levers.

Abstract: A perfumed or edible composition comprising an appropriate carrier and an amount of 5-methyl-hept-2-en-4-one effective to impart its fragrance or flavor to the composition. It imparts a fragrance and flavor reminiscent of hazelnut.

Abstract: A spinning frame of the type having a main drafting zone through which two fiber bands move in spaced parallel relation for subsequent twisting into a single yarn is provided with a first pair of rollers located at the entrance to the main drafting zone, a second pair of rollers located at the exit of the main drafting zone, a pair of endless leather tapes extending about a roller in each of the first and second pair of rollers, and a third pair of rollers for delivering two fiber bands from the main drafting zone to a suitable twisting device.

Abstract: Di- and tetrahydrobenzofuranone of the formula ##STR1## are useful in scenting and/or flavoring agents for imparting thereto a coumarin and coconut note.
