Patent DE-4143107-A1 (DE)
Title: Chemical treatment of liq(s). esp. contaminated waters - comprises intimately mixing with liq. or gaseous reagent, pressure is then increased, liq. is mixed with body of untreated liq.
IPC: C02F1/66
Filed: 1991-12-24
Abstract: A new procedure for the treatment of liqs. with chemical cpds. has the following stages: 1) the reactants are brought into contact in contra-flow and the contact surface of the treatment agent (which is introduced under pressure) is increased by passage through a special mixing elements (4). 2) the pressure is increased so that: a) the chemical equillbrium is moved in the direction towards neutralisation, b) the solubility of the treatment agent is increased, and c) the liq. is super-satd. with the treatment agent. 3) the liq. is mixed with untreated liq. so that: a) the untreated liq. reacts with any residual treatment agent, and b) remaining treatment agent is distributed in the liq. to be treated by a distribution element (5). Also claimed is an appts. for performing the procedure, which is made of metal or plastic and consists of three reaction chambers (1, 2, 3) connected by a pipe system. The conical outlet (6) of the first chamber (1) can be connected to different sizes and shapes of second chamber (2) and its inlet (7) is of the same size as the outlet (8) of the second chamber. The cross-section of the first chamber is not greater than four times the cross-section of the inlet (7). The connection of the first chamber to the second is in the form of a U-shaped tube provided with a valve (9). The third chamber may be in the form of a mixing tank (3a) with an overflow (10) and one or more inlet pipes (8a) for untreated liq. or may consist of an open pond or lake. Flow through the appts. may be by means of pumps or by gravity and the pressure increase in the second chamber may be provided by the head of liq. by gravity or by a reduction in the cross-section of the flow area. The mixing element (4) has a pore size less than 1mm, and is designed to prevent clogging of its pores by calcium deposits. The appts. is provided with a fully automatic control and measurement system. USE/ADVANTAGE - Used esp. for treating contaminated water with chemical agents, for example for neutralisation of alkaline waters with carbon dioxide. The procedure is not damaging to the environment and can be used safely in built-up areas and in the open countryside. It is esp. suitable for aeration of bodies of water, and its throughput exceeds that of currently used procedures by a factor of 4 to 10.

Patent DE-4235029-A1 (DE)
Inventor: SCHWENK PETER
IPC: B41J2/175
Filed: 1992-10-19
Abstract: A cover (1) for a print head (100) of an ink jet printer has a handling section (2) which is of elevated shape. It has a number of filling apertures (3, 4) corresponding to the number of ink supply chambers in the print head (100). The filling apertures (3, 4) communicate with the respectively assigned filling bores (103, 104) of the print head (100). The cover (1) is preferably made of transparent material so that the assignment of the respective filling aperture (3, 4) to a particular ink component is immediately recognisable and the refilling operation can easily be controlled. With the aid of the cover (1), commercially available print heads (100) can be designed to be refillable without changing the basic configuration. The cover (1) can already be fitted on by the manufacturer so that the print head (100) can be supplied as a refillable print head. It is also possible to convert a commercially available, non-refillable print head into a refillable print head by exchanging the cover. The design of the print head as a refillable print head results in considerable ecological and economic advantages. <IMAGE>

Title: Controlling developer bath top-up during offset plate processing - using predetermined data related to plate area, exposure characteristics and required contrast for top-up pump metering
Inventor: KRAGELUND STEEN F
IPC: G03F7/30
Filed: 1992-10-27
Abstract: The method is applied to control the top-up supply to a developer bath (14) diving the processing (3,4,5) of aluminium offset lithographic plates (7) dimensions and surface area of in-going plates (7) via an import sensor (27) which registers their width and leading trailing edge travel. A controller (2) holds predetermined stored data covering all the standard plates (7) signals and three operator contrast print density levels derived from an exhaust pre-run which establishes the plate exposure characteristics and thus the area to be removed. The pump (p) meters the required developer top up (31) from the reservoir (30) via the controller (2). USE/ADVANTAGE - Simple economic means of measuring developer usage resulting in well regulated top-up and high quality output. Cheaper that equivalent systems for, e.g. cine film processing.

Title: Suppression of nucleus formation on insulating layers used as a mask - by adsorbing particles of layer source and removing from surface during CVD semiconductor layer formation
Inventor: MORGENSTERN THOMAS DIPL PHYS
IPC: H01L21/20
Filed: 1992-10-30
Abstract: Nucleus formation suppression on structured insulating layers is claimed, in which particles of layer source material, used for layer deposition, are adsorbed and removed from the surface of the mask material. The novelty is that, at a defined distance from the single crystalline epitaxial structure gp. to be coated, trench-like sinks are formed in the insulating material exposing the single crystalline wafer surface. The distance between the outer edge of the structure gp. and the trench-like sink surrounding it is smaller than the double migration length of particles of source materials adsorbed on the mask material. The max. bridge width of the mask material between the sinks or the structure gps. is smaller than the double migration length of particles adsorbed on the mask material. USE/ADVANTAGE - To suppress nucleus formation on insulating layers used on selective deposition of single crystalline semiconductor layers in a CVD process as mask material. Guarantees defined bridge widths of insulating material between trench-like sinks or structure gps..

Title: Method of enclosing contaminated industrial installations
Inventor: GAISER HERBERT DIPL ING
IPC: E02D27/18
Filed: 1993-04-15
Abstract: In a method of enclosing contaminated power plants (KKW), a starting shaft (3) is sunk outside the contaminated area, and supply galleries (4, 5) are driven from the starting shaft (3) in the direction of the contaminated power plant. Galleries or shafts (B, D) are driven from these supply galleries (4, 5) and are filled with concrete and therefore form the vertical side walls (7, 8) of a container, the base area of which is greater than that of the contaminated power plant and the height of which exceeds that of the contaminated power plant. Galleries (B) are then placed and filled with concrete, whereby a container roof (11) is obtained which can be separated from the side walls (7, 8). This roof (11) is now lowered together with the contaminated power plant carried by it into the interior of the container, whereby the contaminated power plant is enclosed by the side walls (7, 8). A sealing layer is applied to the lowered contaminated power plant. <IMAGE>

Patent DE-4322313-A1 (DE)
Title: Vibrating-plunger nozzle
Inventor: KANIS PAUL-GERHARD DIPL ING
IPC: F02M69/04
Filed: 1993-07-05
Abstract: The invention relates to a nozzle for atomising fuel. The nozzle body (1) has a conical opening. Located in the said opening is a resiliently mounted tappet (2) with a conical head (6). A spring bar (3) which is inserted through a hole in the stem of the tappet (2) presses the tappet head (6) into the conical opening in the nozzle body (1) and closes the said opening in the unpressurised state. As the pressure increases, the tappet (2) is pushed outwards, allowing fuel to flow through the gap between the nozzle body (1) and the tappet head (6). The greater the pump pressure, the larger the gap becomes. The tappet (2) is excited into high-frequency vibrations by the fuel flowing past and these vibrations bring about particularly fine atomisation. The nozzle permits good atomisation and a large control range even with a low pump pressure and a minimum mass flow. <IMAGE>
