Abstract: The invention relates to a device for placing a liquid con a substrate. The inventive device comprises a housing (2) with a liquid receptacle (52), an applicator (30) protruding from the housing, a pump chamber (54) which is connected to the liquid receptacle via a first valve (21) which opens when there is an underpressure in the pump chamber and which is connected to the applicator via a second valve (29), in addition to an actuator (44; 56) with which the volume of the pump chamber can be reduced counter to the force of a spring device (40; 58; 84), wherein the second valve opens in the direction of a reduction in the pump chamber when an actuating element is operated. The invention is characterized in that the valve openings (12, 26; 74, 76) of the first and second valve are arranged on separating walls (4, 6; 66, 68) rigidly connected to the housing, in that the second valve (29; 89) is opened by an overpressure in the pump chamber (54; 82) and in that the wall of the pump chamber (54; 82) is hermetically sealed outwards with the exception of the valves (21, 29; 87, 89).

Title: Holder used for machining device
IPC: B23B29/14
Filed: 1997-07-07
Abstract: The swivel-mounted machining device holder (1) is able to tolerate a certain pressure caused by metal machining before the tool holding device bends. The blade is prevented from breaking because it is locked in place. Wear and tear or a broken blade increase the pressure of machining. The shape of the swivel-mounted machining device holder is important to increase its efficiency.

Patent DE-19757028-A1 (DE)
Inventor: RIEDEL JOERG DIPL PHYS DR
IPC: C05F11/02
Filed: 1997-12-20
Abstract: A process and assembly (28) make a high-grade substitute material for garden peat by the physicochemical breakdown of materials containing lignocellulose. It especially uses residual wood from woodworking or forestry operations. The wood particles are exposed to hot water and/or steam at temperatures in the range 90 to 250 degrees C and a pressure of between 2 and 30 bar. The pH of the resulting peat substitute is adjusted to between 3.0 and 6.6 by temperature control. After heat treatment lasting between 5 and 25 minutes, the mass is subject to adiabatic expansion. The wood-based product is converted to fibers in a process requiring little energy, reduced still further by the use of residual materials in a gasification process. The peat-based material is water-soluble and may be used as a biodegradable herbicide, for the cultivation of mushrooms, and for the cultivation of microorganisms.

Patent DE-19825063-A1 (DE)
Inventor: GOTTSCHALK CHRISTIANE
IPC: B08B3/10
Filed: 1998-06-04
Abstract: The invention relates to a method and system for cleaning semiconductor elements accommodated in a tank which uses ozonized, deionized (DI) ultrapure water. According to the invention, ozone is generated in an ozone generator (3) according to the principal of silent electric discharge while admitting highly pure oxygen. Said ozone is fed to a contactor (7) through which DI water flows. The ozone is then dissolved in the DI water. While optionally admitting additional chemicals, the ozonized DI water is conducted through the tank (12) holding the semiconductor elements in order to clean the same, and the used DI water is carried away (15). In order to stabilize the ozone concentration, CO2 is added to the ozone/oxygen mixture generated by the ozone generator (7).

Abstract: All gas diffusion structures known so far cannot guarantee water balance compensation in the fuel cell, protection against drying and prevention of water deposits while simultaneously ensuring even distribution of reaction gases. In the gas diffusion structure according to the invention, a gradient is produced in gas permeability perpendicular to the membrane by a stratified system This guarantees constant and optimal humidification in all points of the membrane by the formed product water at appropriate operating temperature and appropriate stoichiometry of the reactants. Additional humidification systems can thus be discarded.
