Patent DE-3235736-A1 (DE)
Title: Shutter for photographic cameras
Inventor: WANNERT MICHAEL
IPC: G03B9/44
Filed: 1982-09-27
Abstract: The invention relates to a shutter for a reflex camera. It is a further development of the application P2733174.4 of the same inventor. The invention describes a shutter which permits high shutter speeds, is very sturdy and has a long service life, operates without batteries, and is intended to possess a stabilised shutter speed. The manner of achieving the object is characterised in that a magnet (11) is screwed in at the end of the tube (1), which magnet attracts a piston made of iron. A further stabilisation is created by the membrane (10), which possesses an aperture (36), into which the tip of the adjusting screw (5) penetrates. If the tensioning spring (7) becomes slack, the dynamic pressure is reduced, the curvature of the membrane becomes weaker and the air is expelled more rapidly. As the piston runs down, a retarding suction is created, which is controlled by a regulating spring (6) and a regulating disc (9), which sit movably on the rod (12), in that an air aperture is altered. Upon release, the wheel (15), which sits on a rotatable pivot lever (14), presses against the running surface (37) of a mounted plate (16), which opens the two shutter segments (18). <IMAGE>

Title: Device, in particular for applying an adhesive for laying cables by means of bonding
IPC: B05C17/005
Filed: 1982-09-30
Abstract: In a device for applying a viscous fluid, in particular an adhesive, on to specific areas of elastic, tape-shaped bodies, in particular on to cables, in particular for laying cables by means of bonding, a solution is to be provided with which the application of such viscous fluids to elastic tape-shaped bodies, such as for example cables, can take place in such a way that a continuous operation is possible in a very clean manner, that is to say during cable bonding operations the application and metering of the adhesive only on to specific areas of the cable are to be ensured. This is achieved in that a guiding and metering head (2) is provided with a guide channel (6) for the tape-shaped body (8) and with a fluid metering opening (13), leading into the guide channel (6), for applying the fluid (7) when the tape-shaped body (8) is pulled through the guide channel (6). <IMAGE>
Patent DE-3239088-A1 (DE)
Title: Process for phosphating metal surfaces
Inventor: HECK THOMAS
IPC: C23C22/14
Filed: 1982-10-22
Abstract: The invention relates to a process for phosphating metal surfaces with aqueous solutions containing an oxidising agent, a zinc salt and a nickel salt, which is characterised in that the metal surfaces are brought into contact with solutions which contain     1.6-2.0 g/l of Zn, 0.3-0.6 g/l of Ni,   20.0-24.0 g/l of P2O5, 2.0-3.0 g/l of ClO3,   1.8-3.0 g/l of NO3 and 0.05-0.15 g/l of NO2.   The bath temperature is preferably +50 to +60 DEG C for a treatment time of the metal surfaces of 1.5 to 2 minutes. The process is used in (electro-)dipcoating, in particular in cathodic electro-dipcoating. The process is advantageous for phosphating metal surfaces in a simple and economical manner and for achieving stable layer formation in conjunction with a high phosphating rate, good wet corrosion resistance and good subsequent coating properties with the use of a small amount of oxidising agent and also in the case of poorly phosphatable metal surfaces. A more stable, finer layer formation is obtained with the use of the novel process with a bath having a selected high zinc content and at the same time a low content of oxidising agent.

Patent DE-3241250-A1 (DE)
Title: Device for the qualitative recording of the filling level in liquid containers
Inventor: BARTSCH THOMAS
IPC: H01H36/02
Filed: 1982-11-09
Abstract: The invention starts from devices for the qualitative recording of the filling level in liquid containers, in which a guide body (1) fitted with magnetically actuable contacts (5, 6) projects in a fixed manner into the interior of the liquid container, and in which a float (11) provided with a magnet (13) is mounted movably on the guide body (1) and adopts a position dependent on the filling level. The invention proposes that two contacts (5, 6) be arranged transversely to the direction of movement of the float (11), the contacts (5, 6) being spaced apart in the direction of movement of the float (11). The magnet (13) is movable between the contacts (5, 6), allowing a first signal to be produced in the case of a first filling level and a second signal to be produced in the case of a lower filling level. The contacts (5, 6) are both in the excited condition during an overlap of the range of operating distances. <IMAGE>
Patent DE-3241472-A1 (DE)
Title: Selective data transmission system
Inventor: HAUSMAN FRANZ JOACHIM
IPC: G08C19/28
Filed: 1982-11-10
Abstract: The invention relates to a selective data transmission system with a transmitter and a receiver, where the transmitter has a memory for a digital code signal. By means of adequately known devices, the digital code signal is transmitted in particular by wireless means to the receiver which has a memory for a digital code word, and a comparator which transmits a signal if the received code signal matches the code word. A transmission system of this type could hitherto be implemented only at comparatively high cost, while virtually no security could be implemented against unauthorised use. It was not readily adaptable to the widely differing conditions of use. To overcome these difficulties, it is therefore proposed, in the transmitter, following the occurrence of an alarm signal, to retrieve the code signal from the memory and to combine it with a start signal, and, in the receiver, after the start signal has been received, the received code signal is compared with the code word permanently stored in the receiver. These procedures are repeated N times, where N is an integer greater than 1, and the signal indicating a match between the code signal and the code word is transmitted only after the repetition(s). <IMAGE>

Title: Method and circuit arrangement for representing characters of different size in a dot matrix by means of a dot matrix printer
Inventor: BRUECKNER JUERGEN DIPL ING
IPC: G06K15/10
Filed: 1982-12-08
Abstract: This method uses a memory for storing an image pattern corresponding to the characters, the individual dots of which are converted into bit information items and are stored in a memory. These bit information items are read out and control the printer needles of the print head which are arranged in column form. The conventional printers have a drive by means of which the characters can be represented in a 5:7 or 9:7 representation matrix. Such printers cannot be used for representing videotex in which the characters have a 10:12 dot matrix. This is to be made possible by means of the invention. According to the invention, the printing paper, after a printed line has been printed out, is advanced by in each case the dimension of the printing height, only a particular number of dots of a printing column being printed out in each case and the remaining bit information items of a representation column being stored in a buffer memory. When the next printed line is printed, they are read out and cascaded with bit information items of the next representation line up to the printing height. The process is repeated until a representation cycle, formed by the least common multiple of representation height and printing height, of several printed lines written underneath one another has been run.

Title: Counting mechanism for flow as a function of temperature in central heating systems
Inventor: DANELON LUIGI
IPC: G01K17/06
Filed: 1983-10-10
Abstract: The counting mechanism in accordance with the invention is used, in particular, in central heating systems for generating hot water for sanitation purposes, for heating spaces or the like, the aim being to measure the effective consumption for each hot water consumer. The mechanism divides the incoming hot water into two component flows, of which one flows via a volumetric meter, while the other is united in a manifold immediately downstream of the meter with the component flow running through the meter. In this way, the component flow measured by the meter is proportional to the temperature of the hot water. A maximum temperature is fixed at which, for example, the entire flow runs via the meter, and a minimum temperature at which the entire flow is redirected without flowing via the meter.
