Patent DE-3110839-A1 (DE)
Title: Fitting for guiding and/or regulating flows of media
IPC: F16K27/00
Filed: 1981-03-19
Abstract: The invention relates to a fitting (1) for guiding and/or regulating flows of media. The housing of the fitting (1) consists of a housing part (5) containing an insert. The housing part (5) takes up all the mechanical forces, for example those associated with the pipe or hose connections and the connections to actuating elements (2, 22, 24) and accordingly comprises a mechanically strong part whose composition does not take account of the medium. All areas which come into contact with the medium are covered by the insert (16), which is not subject to any mechanical loading. Consequently, the insert (16) may be composed of a material suitable for the medium to be regulated or carried. The connection of the conduits (8) for the media to the fitting (1) is of corresponding configuration such that those parts which come into contact with the medium likewise differ in terms of the material of which they are composed from those parts which take up the mechanical forces. To achieve this, a conduit (8) is provided with a thrust collar (10) made of a material suitable for the medium, while a screwed nipple (9), which is screwed into threaded holes (6, 7) of the housing part (5), is made of a mechanically strong and/or easily machined material whose composition does not take account of that of the medium. <IMAGE>

The plate (2) may be the base of a screw head (4). A seal (5) can be clamped in between the plate (2) and the opposing plate (3). A sensor protective tube (6), which has an external thread and carries a nut (7) at the open end, passes centrally through the plate (2), the opposing plate (3) and the seal (5). The sensor protective tube (6) can be soldered into the plate (2) or may have an opposing support, for example a nut (8) which engages under the plate (2). As a result of its arrangement and construction, the sensor protective tube (6) (in addition to its original function) also carries out the function of a screw which was previously used together with the nut (7) for clamping the seal (5) in. <IMAGE>
Patent DE-3119979-A1 (DE)
Title: Method and device for drying green bricks made of clay
Inventor: UHRIG WOLFGANG
IPC: F26B3/34
Filed: 1981-05-20
Abstract: Green bricks made of clay are, during drying, moved through a drying chamber (1). The drying energy is delivered by microwave transmitters (21) which are arranged in the drying chamber. The drying chamber (1) has an inlet lock (2) and an outlet lock (3) which are free from microwave transmitters and microwave radiation. The drying chamber (1) is flowed through by air which flows in via inlet openings (17) and flows out via outlet openings (15a). Arranged at the outlet end of the drying chamber (1) is a discharging slide (33) or a discharge gripper (29). By drying with the aid of microwaves, short drying times are achieved, which makes possible continuous drying. The short drying time is based mainly on the fact that, by means of the microwaves, heat can be brought into the interior of the clay mass and thus a rapid drying is possible with simultaneous avoidance of shrinkage cracks. <IMAGE>

Patent DE-3146617-A1 (DE)
Title: Device on displaceable platforms for parking motor vehicles
IPC: E04H6/36
Filed: 1981-11-25
Abstract: Displaceable platforms (11, 12) for parking motor vehicles possess couplings between the platforms. The couplings cause the platforms to be coupled to one another when the platforms of one row are pushed together by a drive arranged at one end, and make it possible subsequently to form a gap between two platforms (11, 12). It is proposed that the coupling members (1, 2) and the contacts (3, 4) of each platform side be connected to form a structural unit (5, 6), use being made in one unit (5) of a peg-like coupling member (1) which is surrounded by a contact carrier. The contact carrier and coupling member are movable relative to one another. As a result, a considerable simplification of the manufacturing complexity is obtained. A secure mechanical and electrical coupling which takes account of the rough operation is achieved. <IMAGE>

Patent DE-3200744-A1 (DE)
Title: Carburettor diffuser of non-rigid material for spark-ignition engines
Inventor: HINTZE WERNER KARL-HEINZ
IPC: F02M19/08
Filed: 1982-01-13
Abstract: The diffuser (1) comprises a hose-like piece of petrol- and oil-resistant, highly elastic material. This hose is mounted in a fixed housing (2). Between outer casing of the diffuser (1) and housing (2) a concentric chamber (3) is created. This is connected to a hydraulic cylinder with piston (4) and filled with a liquid with a high boiling point. In order to prevent wrinkling of the diffuser, this must be installed with radial pretensioning in the housing. Its diameter must therefore be smaller than the diameter of the receiving bore of the housing. Unpressurised hydraulic cylinder means a cylindrical diffuser shape, that is maximum flow cross-section, i.e. maximum engine speed. Idling position is achieved through the smallest flow cross-section, i.e. through corresponding fluid filling in the concentric chamber (3). The fuel nozzle (5) contains a nozzle needle (6) which is coupled to the piston of the hydraulic cylinder (4). By correct profiling of the nozzle needle (6) the required quantity of fuel is adjusted to the quantity of air. <IMAGE>

Title: Method and circuit arrangement for checking and detecting errors during the operation of a multi-digit fluorescent display
Inventor: MICHEL RAYMOND
IPC: G09G3/00
Filed: 1982-02-20
Abstract: Optimally distinguishable character combinations are selected from a 14-segment display to form figures in such a manner that unmistakeable figure patterns are obtained in which a fault is visually recognisable by a corrupted figure being displayed. The check for segments which unrecognisably change a figure is restricted to two segments (b and e). The corresponding segment driver lines (31b and 31e) are conducted via a monitoring circuit (38) which generates a logic signal "1", defining the instantaneous signal state, which is brought into relation with the state existing in a signal line (29b, 29e) from the processor in a logical evaluating circuit (G1 to G6). A resultant criterion (I = 1) controls an error signalling circuit (40). <IMAGE>
Patent DE-3207668-A1 (DE)
Title: Method and tuyère connection for cooling cast strands of metal
Inventor: KRING WILHELM ING GRAD
IPC: B22D11/124
Filed: 1982-03-03
Abstract: In a method of this kind for cooling cast strands of metal, in particular cast strands with the cross-section of billets or blooms, jets of spray or mist are directed at the cast strand transversely to the direction of travel of the strand. To equalise the cooling behaviour of jets of spray or mist (large water droplets/atomised cooling liquid), i.e. to avoid phenomena such as, for example, Leidenfrost's phenomenon or areas which are missed, it is proposed that the liquid is sprayed or misted simultaneously from two nozzles, in each case from the corner region next to the cast strand and from a position at a short distance from the surface to be cooled, and that the length of the jets of spray or mist is adjusted to the width or thickness of the cast strand by moving them closer or further away. The tuyère connection for carrying out this method on the basis of jets of mist (two-component cooling) is designed in such a way that at least one of the feed pipes (6, 10) forms a rectangular tubular frame, to the legs (6a, 6b) of which distributor pipes (8) are connected, these likewise running at right angles as far as the region of the nozzle positions (1a, 1b). <IMAGE>
Patent DE-3208204-A1 (DE)
Title: Printing method for safeguarding banknotes and documents against unauthorised copying
Inventor: SCHIEF ALFRED DR ING
IPC: B42D25/342
Filed: 1982-03-06
Abstract: The invention relates to a printing method for safeguarding banknotes and documents against unauthorised copying. Many measures are known which are intended to prevent this, such as watermarks, metal strips, etc. The invention sets out from the fact that the precisely aligned printing on the front and back is technically complex and cannot be realised by forgers. A periodic structure in linear form is therefore proposed which, when aligned correctly, shows only the fine lines in transmitted light and, with only slight deviation of the position, shows Moiré images.

Title: Device for fastening a cylindrical piece, e.g. a tube or a shaft, for machining
Inventor: LARIKKA LEO
IPC: B25B1/20
Filed: 1982-03-06
Abstract: The subject matter of the invention is a device for fastening a cylindrical piece or part (11), such as a tube or a shaft. The device has two clamping jaws (21) which can be moved essentially horizontally towards one another. The thrust or press faces of the jaws are bevelled at an acute angle to the vertical plane. The angle legs diverge downwards. A third jaw (15) is arranged so that it can move or be moved in the vertical direction to the region below the sloping faces (22) of the two clamping jaws (21). The top surfaces of the cylindrical piece (11) of various diameters can be held in the same height position or at the same level by blocking or locking the third jaw (15) at a given height in conformity with the various tube and shaft diameters. The cylindrical part (11) is secured or fastened by pressing the same between the bevelled faces (22) or by gripping of the horizontally movable clamping jaws (21). The supporting faces (22) can have the form or configuration of a chute to which the fastening clamping jaws (21) extend in uniform material formation along the length of the tube which is to be machined. A third clamping jaw (15) is then unnecessary. <IMAGE>

Title: Endless transport band for transporting margin-perforated recording carriers
Inventor: ALTENBURG HELMUT
IPC: B41J11/30
Filed: 1982-03-29
Abstract: Endless transport bands are used in form sprocket feeds, in order to supply margin-perforated recording carriers to a printing machine and, after the inscription of these, to ensure the further transport of the recording carriers. The object of the invention is to provide endless transport bands for medium to very high transport capacities, the length of which is variable and is therefore adaptable to the respective drive unit, and, along with a low outlay in terms of production, guarantee a fault-free transport of the recording carriers. This object is achieved, according to the invention, in that the endless transport bands have segments which consist of flexible plastics and which, on the one hand, can be connected by means of a strip of plastic foil or have stud-fastening possibilities, by means of which the segments can be stud-fastened together to form an endless transport band, specific teeth corresponding to a sprocket wheel being made wider. <IMAGE>

Title: Process for the production of a gas mixture and apparatus for this
Inventor: BLUMENSAAT JUERGEN DIPL ING
IPC: G05D21/02
Filed: 1982-08-20
Abstract: In a process for the production of a gas mixture, in which the individual components are guided from supply containers into a mixing chamber and are dispensed from the latter as a mixture, optionally with a mixture store being interposed, a highly accurate gas mixing is achieved in that, in the measuring chamber, a density measurement is designed as a buoyancy measurement. Starting from a lower buoyancy limit value, the individual mixing components are assigned, according to their proportion, successive upper buoyancy limit values, at which the subsequent component is respectively fed into the shut-off mixing chamber and the feed of the preceding component is cut off. The buoyancy measurement preferably takes place by means of a buoyancy balance which has a buoyancy-measuring body (17) having a volume large in relation to a tare body (18), with the same surface size. The buoyancy balance is connected to a measurement transmitter (20) which is connected via a control unit (22) to the inlet valves (2, 3, 4) and to the dispensing valve (8) of the mixing chamber (1). <IMAGE>
