Abstract: The invention relates to the use of 2-(3,4-dihydroxyphenyl)ethyl-substituted carbonic acid derivatives as antioxidants or free-radical scavengers, in particular to the use for protecting human cells and tissues from the harmful, aging-accelerating effects of free-radicals and reactive oxygen compounds.

Abstract: The invention relates to the use of 3,4-dihydroxy-mandelic acid as an anti-oxidant and/or free-radical scavenger for protecting the skin, in particular human skin against oxidative damage caused by ultra-violet light and also for protecting cosmetic or pharmaceutical preparations, other objects and foodstuffs against oxidation and/or photo-oxidation.

Abstract: The invention relates to cosmetic and/or dermatological preparations which contain, in part, novel catechol oximes of formula (I). Said preparations can promote, in physiological systems, the natural defense mechanisms against free radicals and reactive oxygen compounds, or can be used as protective agents in cosmetic or pharmaceutical products whose oxidation-sensitive constituents should be protected from autooxidation.

Abstract: The invention relates to hydroxyflavanones, their salts and stereoisomers and their mixtures for suppressing or reducing the bitter and/or metallic taste impression. In addition, the invention relates to nutritional, nutritive or consumable preparations or oral pharmaceutical compositions, characterized in that these have an active content of hydroxyflavanones, their salts and stereoisomers or their mixtures.

Abstract: 2-Hydrazino-1,3-thiazoles, or their salts, can be used as effective constituents in cosmetic and dermatological preparations, and in preparations which are of use in nutrition or consumption, for protecting mammalian cells and tissues, and also the preparations, from the harmful effect of reactive oxygen species and free radicals.

Abstract: Benzaldoximes having at least one aromatic hydroxyl or alkoxy group are effective constituents in topical cosmetic compositions, in particular, skin lightening compositions.

Abstract: The present invention relates to hydroxymandelic acid amides of phenolic amines which can be used as antioxidants or as free-radical scavengers, particularly in the cosmetic or dermatological field, in foods and in cosmetic and dermatological compositions.

Abstract: The electrode arrangement (1) consists of a dielectric substrate (2) on which there are several electrodes (4) with terminal leads. A dielectric layer (6) extends over the electrodes (4) over which there is a screening electrode (7) with an aperture (8) for each of the electrodes (4). The arrangement is especially suitable for a contragraphy apparatus. It can be economically produced.

Abstract: An electro-photograph device having two counter-rotating rolls (2, 5). Roll (2) transports a toner layer, controlled by a blade (4), to a printing zone (6). A voltage is applied between rolls (2, 5), in order to transfer low-adhesion toner from roll (2) to roll (5). Consequently, only toner particles having a specified minimum adhesion reach the printing zone (6). Thus, better print quality is obtained and the expenditure for drive electronics is reduced. A multitude of electrodes (18) are located on the side of a paper carrier facing away from the roll (2). A switching device (19) selectively applies the electrodes with a bias with is related to the biases applied to the rolls (2,5).

Abstract: The device for storing money in a cab is distinguished by the fact that it exhibits, in a lockable housing, one or more openings for the introduction of notes and/or coins, mechanisms for dispensing notes and/or coins, mechanisms for determining the amount to be dispensed and mechanisms for invalidating at least the notes in the event of forcible tampering.

Abstract: Apparatus for feeding and transporting blanks of corrugated paperboard and the like is disclosed wherein a stack of blanks is received on a blank feeding station having a first belt-over-roller conveyor which cooperates with an angularly inclined control gate of a gate assembly to feed blanks from the bottom of the stack beneath the control gate and effect shingling of the blanks, whereafter the blanks are transported to a receiving station such as the feed hopper of a printing press or the like. The control gate is adjustable to vary the shingling relationship of the blanks fed from the bottom of the stack and has a low friction surface thereon facilitating optimum operation.
