Title: Device for lowering the germ level in room air by means of ultraviolet radiation
Inventor: FUCHS PETER
IPC: F24F8/80
Filed: 1986-11-05
Abstract: For conditioning of the room air, the device has at least one reaction chamber which is arranged in one of at least two mutually parallel flow paths for dividing up the room air, to be channelled, into partial streams and is equipped with at least one UV radiator which is designed for UV radiation in a wave range which kills off germs. Expediently, means for controlling the residence time of the room air, which is channelled through the reaction chamber, in the region of action of the UV radiators are provided. There may also be present a plurality of parallel-connected reaction chambers in which the flow rates of the room air may be set differently. The partial air streams emerging from the reaction chambers are then mixed together, so that in each case only a partial degermination of the channelled room air takes place.

Title: Separation device for multiple layer stacks of sheet layers
Inventor: MAYER ADOLF
IPC: B65H3/32
Filed: 1986-12-04
Abstract: In a separating device (1) for the sublayers (3) of a multiple layer stack (2), first a pre-sublayer (36), thicker than the sublayer (3), is moved from the layer stack (2), by means of a displacement device (26), over a supporting body (8) such that an edge region (18) projects freely, so that the sheet layers, co-displaced in an excessive number, below the predetermined separating point (11), of a residual layer (37) sink, because of their lower inherent stiffness than a lowermost intermediate sheet layer (4) of the sublayer (3), downwards within a free space (65) onto a rest body (9). Into the separating point (11) gaping open by this means, a separating-marking element (10) engages, while the separated sublayer (3) is drawn off via a conveyor device (34) for further processing and the residual layer (37) is brought back, via a return device (61), onto the layer stack (2). By this means, in a simple manner, a very precise separation of the sublayers (3) is permitted essentially independently of what type of sheet layers (5) are processed, apart from the relatively stiff intermediate sheet layer (4), in the respective sublayer (3). <IMAGE>

Patent DE-3711936-A1 (DE)
Title: Anti-bombardment cladding
Inventor: SAELZER HEINRICH
IPC: E06B5/10
Filed: 1987-04-09
Abstract: The anti-bombardment cladding is assigned to frame legs of pivotable door and window elements (1 and 2, respectively) and fixed elements (3 and 4, respectively). All the parts delimiting the elements (1, 2, 3 and 4) are covered on one side by chamber combinations, in which resistant inserts are arranged. Each chamber combination is fastened exclusively on parts of the fixed elements (3, 4) and thus does not subject any pivotable door and window element (1 and 2, respectively) to loading. Neighbouring chambers of a chamber combination are preferably separated from one another by a spacing which is spanned in each case by a further chamber which overlaps the chambers arranged in one plane. This provides a variable construction of the chamber combination, the individual chambers reaching beyond the border regions of the elements (1, 2, 3 and 4) although the chamber combination is fastened exclusively on parts of fixed elements. The fact that a comparatively small number of profiles is sufficient for forming a multiplicity of chambers is of particular import. <IMAGE>

Title: Arrangement for guiding or controlling aircraft
Inventor: GOETTING JUN HANS-HEINRICH DIP
IPC: B64F1/22
Filed: 1987-06-04
Abstract: The air traffic on the ground at all airports is controlled from the tower, by air traffic control personnel. Monitoring is carried out mainly visually or via ground-based radar. If lead wires are laid on the runways, landing strips and from there on all the routes to the aprons (ramps) or terminals, an alternating current being passed through these lead wires, the monitoring in the previous form from the tower can be obviated, in conjunction with a sensor and control device in the aircraft, which device makes the aircraft follow the lead wire. For this purpose, the sensor device in the aircraft must be constructed such that it detects the field lines of the conductor and makes these parameters available to the control device. If further sensors are installed, it is possible to detect the height above the ground, the inclination and the location of the aircraft. In conjunction with a central computer system, all the air traffic at an airport from landing approach onwards can be monitored and automated. Equipment for aircraft and airports.

Title: Device for adjusting a daisy-wheel to a zero-position bit pattern of a motor in a printer or office machine of a similar design
Inventor: KERZEL GUENTER
IPC: B41J32/00
Filed: 1987-12-17
Abstract: In program-controlled printers or office machines of a similar design it is necessary for the daisy-wheel (5) to assume at the start of the printing process a specific position with respect to the bit pattern which drives the stepping motor (7). Only in this way is exact setting of the daisy-wheel (5) always ensured. The invention is based on the object of providing a device for setting a daisy-wheel, which can be driven in stepped fashion by a motor, to a zero-position bit pattern of the motor which is simple to switch and easy to handle. This is achieved in that the movable carriage (4) with the daisy-wheel (5) has fixedly arranged control elements which produce electric signals which can be triggered by control marks (63, 64) which are provided on an ink ribbon cassette (6) which can be fitted on a receptacle plate (61) of the carriage (4), and are output via the microprocessor control (20) to the motors (7, 18) for the carriage (4) and the daisy-wheel (5) and to the control element for the inhibiting element (32). The setting device for the daisy-wheel (5) is triggered to adjust to a zero position bit pattern of the motor (7) via the ink ribbon cassette (6) without additional keys or switches having to be actuated. <IMAGE>
Patent DE-3802286-A1 (DE)
Title: Borehole plug with double piston
Inventor: DRESPA GERD
IPC: E21B33/12
Filed: 1988-01-27
Abstract: In underground mining and tunnelling, borehole plugs are used in order to effectively seal the borehole during the grouting with resin and suchlike material. Such a borehole plug has a wedge sleeve at the bottom end facing the borehole mouth. The wedge sleeve is displaceably guided on the filling pipe and is connected via a tubular body to the actual sealing part. The bottom end of the sealing part in turn forms a wedge-shaped piston which can be inserted into the wedge sleeve and the latter can be secured against the borehole wall in the process. The top end of the wedge-shaped piston forms a stabilising tube which forms the extension of the filling tube and ends at the top in the area of the plug head and here has radial bores which enable grouting material under high pressure to be discharged behind a piston disc which in turn displaces filling material and thus forces the tubular body to expand. The borehole is thereby additionally sealed in the area of the sealing part and the entire borehole plug is effectively secured in the borehole. After the piston disc has covered an appropriate distance, it crosses discharge openings so that the filling material can then penetrate into the borehole and become effective here. <IMAGE>
