Patent DE-3400529-A1 (DE)
Title: Process for denitrifying water
Inventor: KRATZENSTEIN KLAUS ING GRAD
IPC: C02F3/34
Filed: 1984-01-10
Abstract: The invention relates to a process for denitrifying water, the nitrate contained in the water being biochemically reduced with the aid of denitrifying microorganisms in the presence of a carbon donor, after the water containing the added carbon donor has been contacted with the carbon donor-oxidising microorganisms to eliminate the dissolved oxygen contained in the water, the excess carbon donor being used in the denitrification. To reduce the reaction time and to avoid toxic products, a sugar solution as carbon donor and additionally a potassium phosphate and/or ammonium phosphate solution are added to the untreated water. By operating at elevated pressure, the otherwise highly interfering liberation of gas in the filter bed, which blocks the reaction chamber, can be excluded.

Title: Vehicle hydraulic brake system with an antilock device
Inventor: REINARTZ HANS-DIETER
IPC: B60T13/14
Filed: 1984-10-26
Abstract: In a vehicle brake system a brake tandem master cylinder (1) can be actuated by a brake booster (2), which is fed from a hydraulic energy supply system (10). Wheel brake cylinders of a lefthand front wheel brake (FL) and a righthand front wheel brake (FR) are arranged on the brake master cylinder (1) by way of brake lines (30, 31), in which lie the control valves (35, 36, 38, 39) of an antilock device.

Patent DE-3447573-A1 (DE)
Title: Method for sealing containers filled with foodstuffs, for example coffee powder, and device for implementing the method
Inventor: HELLWIG HERBERT
IPC: B65D51/20
Filed: 1984-12-27
Abstract: The invention relates to a method for sealing containers filled with foodstuffs, for example with coffee powder, a device for implementing the method and a cap-like seal which can be used with the process. A diffusion seal is mounted on the container under pressure and the cap-like seal is, while covering the sealing film, made to engage with the outside of the container by being screwed or pressed onto it. The aim of the invention is to make the diaphragm supports for the diffusion seal, which are conventionally used when containers are sealed and which do not have a function once they have been pressed onto the edges of the container, superfluous, so saving money and material. Care is hence taken to ensure that the diffusion seal and the seal are mounted onto the container one after the other and independently of one another, and that the sealing pressure which acts on the diffusion seal mounted on the edge of the container as the latter is closed is exerted directly by the part of the inside surface of the seal which is immediately opposite the edge of the container. The embodiment of the cap-like seal according to the invention makes such a procedure possible. The device according to the invention includes an add-on modular unit assembly for mounting the diffusion seal, which can be attached to conventional installations without conversion measures, to permit implementation of the method according to the invention.

Patent DE-3505175-A1 (DE)
Inventor: BOLZ ALFRED
IPC: B01F7/30
Filed: 1985-02-15
Abstract: The mixer comprises a mixing container 1 with a vertical axis, a conical side wall and a container bottom, as well as a mixing screw which is fastened to a shaft and is driven in rotation by means of a drive arranged underneath the container bottom. The upper end of the mixing screw is rotatably mounted in a bearing of a rotatingly driven swivel arm, which for its part is rotatably driven in a central housing flange on the upper side of the mixing container by a drive arranged there. To increase the operational reliability, axial changes in length of the mixing screw shaft are taken up in a bearing arranged at the swivel arm, by the mixing screw shaft being designed as a knockout spindle. Furthermore, the swivel arm is designed as a simple arm without any built-in gear mechanism, so there are no seals, gear components or the like in the product space. <IMAGE>

Title: Multi-layer, thermoformed interior lining for motor cars, in particular motor-car roofs, and process for repairing thermoformed mouldings
Inventor: WAGNER WERNER DIPL CHEM DR
IPC: B60R13/02
Filed: 1985-05-04
Abstract: A multi-layer, thermoformed interior lining for motor cars, in particular motor-car roofs, has a layer of thermoplastic foam which is provided on both outer sides with in each case a thin layer of glass fibre nonwoven fabric. As a result of the glass fibre layers, such an interior lining part has stiffness and installation properties which are outstanding per se. Due to the glass fibre layer, however, cavities occur, in the region of severe deformations, during thermoforming. According to the invention, these are filled with foam so that, as a result, a continuous layer with substantially uniform mechanical properties is re-established. The introduction of the foam into the cavities takes place by pouring in liquid plastic provided with a foaming agent. The plastic foams without constriction in moulds. Excess material is cut away. <IMAGE>

Title: Warm or hot air humidifier
Inventor: JUENGLING HELMUT
IPC: F24F6/00
Filed: 1985-06-27
Abstract: The invention relates to an air humidifier, in which warmed or heated air is blown or pressed or sucked into or through a water container or through a water bath. The artificially generated mist, which arises as a result of the meeting of the hot element air with the cooler water bath, is guided via a corresponding device into a secondary chamber and is washed out and neutralised in a correspondingly temperature-controlled water bath by means of an air distributor. Chemical additives have the effect that breathing air which is pure and well-metered by means of electronic control leaves the air humidifier. Electronic or electric regulating installations control the entire activity of the air humidifer. The present embodiments are an addition to:  P 3518041.2 Adjustable air humidifier for suction-air and compressed-air operation.

Title: Device for setting terminal pins joined integrally in the form of strips into a work-piece
IPC: H05K13/04
Filed: 1985-11-12
Abstract: The invention describes a device for setting pre-formed terminal pins, with pressed-on end sections, and joined integrally in the form of feeder strips (14), into a work-piece (10), with a gripping device to push the strip forwards step by step, and a stamp (20), arranged at right angles to the transport device, to separate the terminal pin which is respectively at the front. It is essential that the gripping device (42, 35) is formed so as to push the strip (14) forwards parallel to the surface of the work-piece as far as the limit stop (51), whereas the stamp can be moved at right angles to the surface of the work-piece. As it moves downwards, the stamp breaks off a terminal pin, and then carries it along in a stamped groove (57), which is on its lower rearward-facing end, and projects from the front side by the set height. The essential advantage is that the stamp (20) carries out a double function, that is the functions of both a separating tool and a setting tool. <IMAGE>
