Patent DE-3525970-A1 (DE)
Title: Greenhouse
Inventor: EBERLEIN HERBERT DIPL ING
IPC: A01G9/24
Filed: 1985-07-20
Abstract: In previously known greenhouses, the ventilation devices are still always designed in such a manner that air flow speeds, which of necessity are of different strengths, prevail in the interior of the greenhouses. This leads to different climatic conditions in such houses. In regions of relatively weak air flows, mould can therefore very easily form in the ground and on the plants. The greenhouse (1) according to the invention avoids or reduces this disadvantage by among other things at least one ventilation device (27) being formed by a roller shutter (9) consisting of light-permeable lamellas (10). <IMAGE>

Patent DE-3545336-A1 (DE)
Title: Motor vehicle
Inventor: GUSINDE HEINZ
IPC: B60K13/02
Filed: 1985-12-20
Abstract: In a road, rail, cross country or water vehicle with a water-cooled, pressure-charged diesel or petrol engine the cooler for the charge air and the radiator for the engine cooling water are generally arranged immediately one in front of the other so that a flow of cooling air flows through them in succession. Due to the special arrangement of the cooler in the vehicle, in the case of a rear-engined bus, for instance, at the end of a cooling air duct which opens out into the side wall of the vehicle behind the rear wheels, or due to environmental influences, vehicles travelling ahead and the like, the arrangement formed from the two coolers seated one in front of another can become dirty and encrusted. According to the invention, the charge air cooler is removably mounted on the radiator, preferably so that it can be swivelled away. According to another embodiment of the invention, where a cooling air duct is used, the radiator is arranged at its one end and the charge air cooler shifted to the other end, where, for cleaning purposes, it can be swivelled out from the vehicle. The two coolers, which according to the invention are constantly or temporarily separated from one another, can in this condition be effortlessly and thoroughly cleaned.

Title: Device for the automatic rinsing of an ink jet print head
Inventor: HUMBS ROLF DIPL ING
IPC: B41J2/165
Filed: 1986-03-05
Abstract: The ink jet print head has an actuating element in the form of a lever which acts mechanically on the ink supply system of the ink jet print head and is coupled to the sealing element in such a way that, when the sealing element is actuated, preferably before the ink outlet apertures are sealed off, the actuating element squeezes the ink supply system locally and thus, due to a brief pressure increase, causes ink to emerge at the ink outlet apertures.
Patent DE-3608807-A1 (DE)
Title: Position transmitter and its use
Inventor: HOPF WOLFGANG
IPC: G01D5/22
Filed: 1986-03-15
Abstract: In a volume meter, for example a water meter, a ferromagnetic rod (9) is connected to the rotating measuring element (1), which rod, together with the measuring element (1), revolves in the housing (4) of the water meter. Outside the housing (4) of the water meter, two coils (11, 12) are arranged diametrically opposite one another in such a manner that the ferromagnetic rod (9) is located in extension of the ferromagnetic cores (13, 14) of the two coils in one of its positions. In this position, the two coils are magnetically coupled, while they are decoupled in the position of the magnetic rod (9) perpendicular thereto. A pulse transmitter (15) is connected to one coil (11) and a pulse receiver (16) is connected to the other coil (12). The magnitude of the output signal of the receiver (16) depends on the coupling between the coils (11, 12) and is therefore characteristic of the position of the magnetic rod (9). Using pulse sequences with an extremely small duty ratio allows the water meter to be observed in an energy-saving and, at the same time, reaction-free manner. <IMAGE>
Patent DE-3617993-A1 (DE)
Title: Driving school roof sign
Inventor: HOEVENER WILLI
IPC: B60R13/00
Filed: 1986-05-28
Abstract: The object of the driving school roof sign is to mark a driving school car so that it is visible a long way off from the front and rear, to give other road users timely warning of the presence of a driving school car, with all the risks which this entails. The driving school roof sign can have a reflective film bonded to it or may also be equipped with a lighting assembly when legal permission for this has been given. The driving school roof sign is characterised in particular by the three securing systems in the mount: firstly by four rubber suckers which cause the sign to adhere to the car roof by means of vacuum-induced suction, secondly by an elastic fastening cable which is hooked into the roof rail on the left and right of the vehicle and by an additional fastening cable on the rear part of the roof sign, which cable is hooked in like the other cable, securing the sign against involuntary separation from the roof. The material used in the roof sign virtually excludes the danger of injury in the event of collisions with pedestrians, cyclists and motor bike drivers. The essential advantages of the new roof sign therefore reside in the fact that the sign is easily visible, in the three securing systems used when the sign is fastened to the roof, in the fact that the sign can be easily and conveniently handled when it is being mounted and dismounted and in the avoidance of injury in the event of accidents involving driving school cars.

Title: Device for measuring the wall thickness of pipes (tubes)
Inventor: LANG RAIMUND DIPL ING
IPC: G01B17/02
Filed: 1986-08-28
Abstract: In a device for measuring the wall thickness of pipes by means of an ultrasonic probe, the ultrasonic waves generated by the probe are temporally compared with the reflected waves. For this purpose, the probe has a magnet which premagnetises the pipe wall in the axial direction, as well as a transmitting and receiving coil which generates a magnetic field which is superimposed on the premagnetising field. In order to be able to measure the wall thickness of an annular section of the pipe, the magnet consists of a ring magnet which surrounds the tube and generates a magnetic flux in the axial direction beyond the entire circumference of the pipe. The coil consists of a ring coil surrounding the pipe, and the reflected waves are evaluated in terms of width and/or amplitude.

Title: Process for producing glass fibres with very low optical attenuation
Inventor: HEITMANN WALTER DR ING
IPC: C03B37/027
Filed: 1987-04-16
Abstract: In a process for producing glass fibres with very low optical attenuation, the end of a cylindrical glass preform 1 is heated until viscous and the viscous end is then drawn out via the stage of an onion 3 to form a thin glass fibre 4. To compensate for inhomogeneities in the glass, shortly after its emergence from the onion 3, the glass fibre 4 is guided through a tempering zone of constant temperature in the form of a tubular kiln 8. The temperature in the tempering zone is some 100@C lower than in the onion 3. It may be also chosen such that the diameter of the glass fibre 4 is reduced somewhat as it passes through the tempering zone and thus a precise adjustment of the diameter is carried out. The interior of the tubular kiln 8 may be flushed with helium during the drawing process (Fig. 2). <IMAGE>

Abstract: The invention concerns a procedure and arrangement for processing rastered, digitised images in evaluation devices. It can preferably be used to process images in robotics, in visual monitoring of industrial processes and inspection, in automatic image analysis for pre-processing (restoration, making thinner, making thicker) raster images of objects, e.g. to identify written characters. Image processing with a variable image window size is possible at low hardware cost and with simple implementation of the image processing operators. According to the invention, at every k'th step of the procedure, the assignments of the pixels of a (uk+1 . uk+1)-sized image window, where:  uk+1 = uk-2,  u0 = N, and  k = 0 ... (N-3)/2 are modified or checked by evaluation of a (3 . 3) image window around the respective pixel of the (uk+1 . uk+1) image window, depending on the respectively selected image processing operator and the fulfilment of one or more specified logical functions. The raster assignment is modified in every k'th step of the procedure except the last.

Additional construction space for the displacement transducer (31) is not required, since the latter is integrated in the steady rest (1). <IMAGE>
Patent DE-3726137-A1 (DE)
Inventor: MUELLER MATTHIAS
IPC: B65B39/00
Filed: 1987-08-06
Abstract: In apparatus for filling open-top sacks with a dusty commodity a filling nozzle 10 has, in addition to its usual closing flaps 13,14, spreader flaps 17,18 which are pivotable about horizontal axes 15,16 disposed transversely to the pivot axes of the closing flaps 13,14. The closing flaps 13,14 and the spreader flaps (17,18) are surrounded by a resilient tubular member 21. The bottom rim of the tubular shaped member 21 is initially spread apart by the spreader flaps 17,18. Spreader tongs 19,20 grip the sides of the sack, follow the movement of the spreader flaps 17,18 which pivot inwardly as the flaps 13 and 14 pivot apart thereby spreading open the end of the tubular member and surrounding sack mouth. The top edge of the sack is thus pulled tightly onto the outer surface of the shaped member 21, whereby the inner surfaces of the top edge of the sack are protected against soiling. An intermediate storage space is formed by the prism-shaped closing flaps (13,14) and by the spreader flaps (17,18). Occlusions of air in the commodity being filled are removed through openings provided in the closing flaps (13,14) and through air discharge pipes whereby the development of dust is substantially.   <IMAGE>
