Abstract: The invention relates to a device (1) for massaging muscles in the oral cavity comprising a body (3) with drive means (5) and a power unit (7), an extending element (9) detachably coupled to the body (3), and two massage units (11) coupled to an end portion (13) of the extending element (9), wherein the massage units (11) operate with an alternately rotating movement, which rotates about a rotational axis (15) essentially perpendicular to the end portion (13). The invention further relates to a method for massaging muscles in the oral cavity such a device (1), wherein the massage units (11) massage the muscles in the oral cavity with an alternately rotating movement. Even further, the method may be used for reducing or eliminating snoring by massaging muscles in the oral cavity using such a device (1).

Abstract: The invention relates to a reaction vessel (1) for producing a sample, in particular a crystal, from a substance in solution or in liquid form, having several reaction chambers (6) each forming a separate gas chamber, consisting of at least one housing part, and each reaction chamber (6) has a reservoir (7) and several reaction areas (8) co-operating therewith, connected to one another and to the reservoir (7) in order to exchange gas. The reservoirs and the reaction areas co-operating with them are disposed immediately adjacent to one another in rows, distributed in a predeterminable, identical manner, these rows running parallel with one another. Each row of reservoirs (7) therefore co-operates with at least one row of reaction areas (8).

Abstract: A fiber composite is produced by continuously pressing together a thermoplastic melt and a glass fiber mat or tape in a double belt press and cooling the composite under pressure. The double belt press is sealed off on both sides by endless, traveling belts made of a compressible material.

Abstract: A naphtha-soluble, hydrogenated C.sub.1-4 -alkyl C.sub.6-10 -aryl ketone/formaldehyde resin, having an oxygen content of at least 6% by weight and a softening point of at least 70.degree. C. can be produced by a process comprising the step of hydrogenating a C.sub.1-4 -alkyl C.sub.6-10 -aryl ketone/formaldehyde resin under a hydrogen pressure of at least 200 bar and a temperature of 140.degree.-300.degree. C., in the presence of a nickel, palladium, palladium/copper or palladium/nickel catalyst. These resins are useful, for example, as additives to improve the hardness of varnishes and other coatings.

Abstract: A process for the catalytic skeleton isomerization of n-alkenes to isoalkenes comprises contacting the n-alkene with a fluorinated aluminum oxide as the catalyst at temperatures of 250.degree.-550.degree. C., in the presence of 0.5-150% by weight of water, based on the weight of the alkene employed and replenishing the fluorine discharged from the catalyst in metered amounts, continuously or discontinuously, using, e.g., a volatile fluorine compound. The catalyst, partially deactivated by coking, is regenerated by burning it off with an oxygen-containing gas in the presence of steam.

Abstract: A device is provided for counting and sorting coins of various sizes. The coins are supplied from a container for unsorted coins to a guide channel adjacent thereto for guiding the coins individually and successively. The guide channel has a continouus reference edge and a base provided with openings which correspond in size to the sizes of the types of coin. A counter detects coins in the guide channel without contact. Spring loaded levers and/or conveyor belts or the like are provided for mechanically urging the coins against the reference edge.

Abstract: An apparatus for controlling a photogrammetrical camera includes a frosted glass adjacent to which or in an optically conjugate plane thereto a transparent planoparallel sheet of voltage sensitive material is arranged. Spaced electrodes are allocated to the one face of said sheet and a sheet electrode to the other face. Each of the spaced electrodes is connected to respective outputs of an electronic counter, which in dependence of a tunable pulse generator applies voltage pulses to the spaced electrodes and the sheet electrode, both sandwiching said sheet of voltage sensitive material and rendering visible the inbetween portions of said material when submitted to a potential so that lines or a cyclic pattern of lines appear. The voltage sensitive material can be liquid or gaseous or solid and can be sandwiched between two substantially plano-parallel plates which have the respective electrodes or electrode on their inner faces.
