Patent DE-3402009-A1 (DE)
Title: Working appliance
Inventor: MOECKEL GUSTAV
IPC: B44C7/02
Filed: 1984-01-21
Abstract: The invention relates to a hand-operated novel working appliance, which can be used to remove old paintwork or paint residues, old wall coverings, old roofing felt and old external and internal plastering, with satisfactory results, and substantially reduces the laborious manual labour hitherto required for this purpose. The appliance contains two spatula-like tools which are mounted in guides and can be moved rapidly back and forth, in contact with each other on the broad sides. To this end, the working appliance contains a control cylinder which is driven by an electric motor, bears control cams, moves the two spatula-like tools (6A, 6B) against force of a spring and then releases them again when the spring is tensioned, so that they are pushed by the force of this spring onto the surface (7) which is to be processed. The two spatula-like tools (6A, 6B) are interchangeably secured in securing devices (5A, 5B) which are connected to guide rods (3A, 3B) which bear lugs which are moved by the control cams against the force of the spring. <IMAGE>
Patent DE-3409810-A1 (DE)
Title: Method of producing gravure forme cylinders, which are variable in depth and area, by means of matt film or film support halftone positives
Inventor: BIEHL KARL MARIA
IPC: G03F5/20
Filed: 1984-03-16
Abstract: By using a matt film halftone positive on the correct side for producing a gravure forme cylinder and exposure through the matt film halftone positive with the film thickness required in each case onto the light-sensitive pigment paper or etching film, awkward and disadvantageous operations are saved which avoid the formation of moiré, and by the light, fine granulation of the matt film, an even exposure and a precise vacuum are produced, the "sun formation" is largely suppressed and an absolute contact with the light-sensitive pigment paper or etching film is produced. If a film support halftone positive is used, a thin matt film remains between the light-sensitive pigment paper or etching film and the halftone positive during the entire exposure time. As a result of this method, a gravure forme cylinder is produced, which has the characteristic of a gravure cylinder which is variable in depth and area.

Patent DE-3431568-A1 (DE)
Title: Process for the denitrification of water
Inventor: KRATZENSTEIN KLAUS ING GRAD
IPC: C02F3/30
Filed: 1984-08-28
Abstract: The invention relates to a process for the denitrification of water, the nitrate contained in the water being biochemically reduced with the aid of denitrifying microorganisms in the presence of a sugar solution, after the water with the added sugar solution has been brought into contact with the sugar-oxidising microorganisms to eliminate the dissolved oxygen contained in the water, the excess sugar being used in the denitrification. In addition to the sugar solution, a potassium phosphate solution and/or an ammonium phosphate solution is added to the water to be treated. The turbidity caused in the denitrified water is removed by treatment of the water with aerobic microorganisms, while the denitrification vessel is backwashed with an inert gas, in particular nitrogen.

Title: Dispatch container
Inventor: STUERZER FRANZ DIPL ING
IPC: B65D71/06
Filed: 1984-10-23
Abstract: This dispatch container for consumer packages (10) consists of a tray (12) and a film wrapping (14) which covers the consumer packages and the tray. The tray (12) preferably has one or two upwardly projecting edges (18, 20) on the longitudinal sides, and at least one perforation line (22) is arranged in the film wrapping (14), which perforation line has a desired spacing from the bottom surface (16). The perforation line (22) preferably runs at the height of the edge or edges (18, 20). When the upper part of the film wrapping (14) has been separated, the film surfaces on the narrow sides of the tray supplement the tray to form a structure with four edges. The tray consists of a simple rectangular cardboard blank on which parallel perforation lines or lines of weakness are formed. This results in a simple type of packaging for such dispatch containers. <IMAGE>

Patent DE-3446111-A1 (DE)
Title: Method for the compaction of granular moulding materials
Inventor: TANNER HANS
IPC: B22C15/00
Filed: 1984-12-18
Abstract: To compact granular moulding materials, in particular foundry moulding materials, the invention proposes a method in which the moulding composition is compacted by means of a compressed-air impact on the upper side of a loose moulding composition. The intensity of the compressed-air impact necessary for compaction is achieved by setting the volume of the mould space and the volume of the pressure space in mutual dependence, by enriching the pressure space with compressed air to a maximum of 10 bar and completely equalising the pressure building up due to this compressed air and taking effect above the moulding composition with the pressure decreasing simultaneously in the pressure space, this being done in a time of 0.1 s at the maximum, by maintaining the resulting pressure for at least 0.12 s and by reducing this pressure to normal pressure in a time greater than 0.2 s. This method makes it possible to convert compressed-air pressures of from 1 bar to 10 bar into compressed-air impacts and to apply the quantity of air moved during this process in massive form to the surface of the moulding material.

Title: Water box for heat exchangers
Inventor: THOMAE RUDOLPH DIPL ING
IPC: F28F21/06
Filed: 1985-02-16
Abstract: The invention relates to a water box, consisting of a base plate made from metal or plastic and a cover part made from plastic, for heat exchangers which are arranged in the coolant circuit of a liquid-cooled internal combustion engine and whose tubes and any cover parts are sealed by means of elastic seals in the base plate. In accordance with the invention, the tubes for the coolant, which penetrate the base plate, are sealed by means of sealing sleeves made from an elastic material and by multiple mechanical widening in the water-box base, all the sealing sleeves being injected or vulcanized onto the insides of the tube openings in the base plates. The injection or vulcanization of the sealing sleeves into the tube openings of the base plates is expediently performed simultaneously at all the sealing points of a base plate. In the case of a metal base plate, the rim seal for sealing between base plate and cover part is also injected or vulcanized at the same time as the tube seals. This rim seal is omitted in base plates made from plastic. <IMAGE>

IPC: G11B27/024
Filed: 1985-03-16
Abstract: A synchronisation system for colour television signals in accordance with the NTSC or the PAL standard is proposed. In this system, the synchronisation signals of a reference signal source are matched to the synchronisation signals of a first outputting magnetic tape device by means of a synchronisation signal adapter circuit, for joining the colour video signals, coded in accordance with one of the two standards, together in the correct phase during the storage on magnetic tape, and the video signals from the first magnetic tape device are matched in horizontal and vertical direction to the phase of a second recording magnetic tape device by means of a digital synchroniser known per se. The system enables editing of any field of a sequence to any other one of this sequence because the circuit specified is capable of transforming any field of an 8-V sequence into any other one.
