Abstract: A daylight hand-lamp for checking painted surfaces, in particular in the field of paint repair work on motor vehicles. The light spectrum is formed homogenously such that at a distance of between 30 cm±0.5 cm in a spectral range having a wavelength of 400 to 700 nm, a daylight deviation average value in a central area and an inner periphery is less than 20%, or the average value of a spectral stability factor is less than 10% with respect to the beam center in the central area and inner periphery.

Abstract: A daylight portable lamp for inspecting painted surfaces, in particular during paint repair work on motor vehicles, has a setting device for setting the light intensity. The setting device has an operating element that can be adjusted between a minimum position and a maximum position, the light intensity being set to a minimum in the minimum position and the light intensity being set to a maximum in the maximum position. When the operating element is arranged in the vicinity of the minimum or maximum position returns automatically to the relevant minimum or maximum position on the basis of a spring restoring force. The operating element can be arranged infinitely variably in at least one transitional adjusting region between the minimum and maximum position without the operating element returning automatically to the minimum or maximum position, so that in the transitional adjusting region the light intensity can be set infinitely variably by the operating element.

Abstract: A device for coating surfaces, particularly coloured or painted surfaces, using a spray gun which is supplied by a supply device with the material to be sprayed. The supply device includes a material container which can be pressurised, and a pressure element is provided on or in the material container itself.

Abstract: A daylight portable lamp for inspecting painted surfaces, in particular in the course of paint repair work on motor vehicles, includes at least a head part with a light-exit opening, through which the light that can be produced by the daylight portable lamp can leave, and a sleeve, which surrounds the light-exit opening and is produced from an elastic, preferably rubber-elastic, material, arranged at the light-exit opening.

Abstract: A water-dispensing appliance is provided, in particular for dispensing drinking water, comprising a water inlet which can be connected to a water-supply device, also comprising a dispensing device with a water outlet, via which water can be dispensed from the appliance, the dispensing device being connected to the water inlet via a main line which has a downstream portion and an upstream portion, and also comprising a water heater. The water-dispensing appliance has a return line, of which the start is line-connected to the downstream portion of the main line and the end is connected to the upstream portion of the main line, and the appliance also has a delivery unit in order for water heated up by means of the water heater to be delivered through the main line from the upstream portion to the downstream portion.

Abstract: The invention relates to a dispensing arrangement for a water-dispensing appliance which is designed in particular for dispensing drinking water, having a valve device which has a valve body that can be positioned with sealing action against a valve seat, and having a dispensing body which has a first inlet and a second inlet, flow-connected to the first inlet, for the connection of water-feed lines and also has an outlet which is intended for dispensing water and is in flow connection with the first inlet and the second inlet. The flow connection between the two inlets and the outlet takes place via a channel portion which carries at an end the valve seat for the valve body, the valve seat forming a flow-deflecting element in order to change the flow direction of the water flowing from the first inlet and/or from the second inlet to the water outlet by at least 90°. The invention also relates to a water-dispensing appliance with a dispensing arrangement of this kind.

Abstract: The invention provides a method and a device for the production of an alkali metal hypochlorite solution, in particular a sodium hypochlorite solution, having at least one non-divided electrolytic cell (12), means (20, 22, 24, 26) for supplying a brine solution into the electrolytic cell (12) at a defined volumetric flow rate and a defined salt concentration, and having an a.c. voltage source (18) for the production of current across the electrolytic cell (12). The current intensity is adjusted to a fixed value so that the concentration of chlorate produced during electrolysis is limited to a maximum of 1.5 g/l, preferably to 0.6 g/l.

Abstract: Enantioseparation methods using chemical compounds which contain the chiral 9,11-substituted-10,11-dihydro-cinchonan skeleton (9,11-Subst.-DHC) and the precursors thereof with the 9-substituted cinchonan skeleton (9-Subst.-C) are described and discussed. The chiral compounds of the present invention are based on cinchonan derivatives containing amide structure elements which support effectively and co-operatively the enantioseparation of chiral acidic selectands involving also ion-pair and ion-exchange binding mechanism between the strong amino group of the selector and the acidic group of the selectand. The methods of enantioseparation of the present invention are related to stereoselective liquid-liquid and liquid-solid type extraction principles and fractionated crystallization employing cinchonan derivative type selectors.
