Abstract: A gearshift lever for a single-track or multi-track motor vehicle comprising a lever arm and at least one gearshift pedal. The gearshift pedal is for the gearshift lever of a single-track or multi-track vehicle. To prevent damage to the footwear and to be able to execute the shifting process without a great deal of physical effort, there are provisions for the gearshift pedal of the gearshift lever to be fastened to the lever arm so as to be so as to be rotatable around the axial direction of the gearshift pedal. As a result, a situation is achieved in which the gearshift pedal can roll off the shoe during the shifting process in the case of a motorcycle, for instance.

Abstract: The invention relates to a gearshift lever for a single-track or multi-track motor vehicle comprising a lever arm and at least one gearshift pedal. The invention further relates to a gearshift pedal for the gearshift lever of a single-track or multi-track vehicle. To prevent damage to the footwear and to be able to execute the shifting process without a great deal of physical effort, there are provisions as per the invention for the gearshift pedal of the gearshift lever to be fastened to the lever arm so as to be so as to be rotatable around the axial direction of the gearshift pedal. As a result, a situation is achieved in which the gearshift pedal can roll off the shoe during the shifting process in the case of a motorcycle, for instance.

Abstract: The present invention relates to a device for delivering heat comprising at least one heat reservoir, and at least one electrical heating element for heating the at least one heat reservoir, wherein at least one of the at least one heat reservoir is a latent heat reservoir.

Abstract: The invention relates to a method for producing L-ascorbic acid from 2-keto-L-gulonic acid or 2,3-4,6-diacetone-2-keto-L-gulonic acid. The reaction is carried out in the presence of water and hydrogen halide and the concentration of the hydrogen halide in water is greater than 37 wt. %.

Abstract: The invention relates to an integrated CMOS circuit for use at high frequencies with active CMOS components (12) and passive components (16, 18, 20). The active CMOS components (12) are formed in a semiconductor substrate (10) which has a specific resistivity in the order of magnitude of k&OHgr;cm. In the semiconductor substrate (10), and under the active CMOS components (12), a buried layer (22) is formed which has a specific resistivity in the order of magnitude of &OHgr;cm. The passive components (16, 18, 20) are formed in or on a layer (14) of insulating material which is arranged on the semiconductor substrate (10). A conducting contact layer (24) is arranged on that surface of the semiconductor substrate (10) which is not facing the layer (14) of insulating material.

Abstract: A potted device, especially a potted, explosion-protected electromagnet comprising a coil (70), preferably embedded in a potting compound (12) in a housing (10), and a ferromagnetic circuit (60), which can be connected to external lines via contact elements (20) arranged inside the housing and likewise embedded in the potting compound (12), is characterized by the fact that the contact elements (20) are arranged in a cavity in such a way as to protrude beyond the potting compound (12) that closes the housing off at its end face, the cavity being formed by a cover element that can be mounted on the housing in the area of the contact elements (20), and that a wiring duct, which is connected with the cavity, is provided in the potting compound.

Abstract: The present invention concerns a novel method of flame-proofing flammable material which comprises treating said material with a compound of the formula: ##EQU1## WHEREIN N IS 1 OR 2, AND R, when n is 1, is a radical of the formula ##EQU2## wherein R.sub.1 and R.sub.2 are substituents e.g. alkyl, or R.sub.1 and R.sub.2, together with the nitrogen atom, form a heterocyclic ring or R, when n is 2, is a radical of the formula ##EQU3## wherein R.sub.1 and R.sub.4 are substituents e.g. alkyl and R.sub.3 is a hydrocarbon bridge e.g. alkylene, or R.sub.1, R.sub.2 and R.sub.4, together with the nitrogen atoms to which they are bound, form a heterocyclic ring, or a group of the formula ##SPC1##Wherein m is 1 to 5, and novel compounds (i.e. when n is 2) useful as flame-proofing agents.
