Patent DE-4241890-A1 (DE)
Title: Bonding grinding material to plate - using grinding material attached to paper backing by tacky slow-setting heat-resistant adhesive which remains on paper when peeled from grinding plate
Inventor: MARTON MIKSA
IPC: B24D9/08
Filed: 1992-12-11
Abstract: The grinding sheet (2) is secured to the grinding plate (1) by an adhesive (9) which is tacky and slow setting and which is heat-resistant and gives durable adhesion. Pref. the adhesive retains its characteristics on rising temps., and the adhesion increases as the temp. rises. The adhesive remains on the grinding paper (2) when it is peeled clear of the grinding plate (1). The stiffening layer (8) is a low-stretch shear-resistant material, as a woven, nonwoven or netting of natural or synthetic fibres, or a plastics film. The adhesive is covered by a protective layer, such as waxed paper, which is larger than the grinding paper (2) to give a projecting edge of at least 0.5 cm and max. 3 cm, and pref. 1 cm. ADVANTAGE - The system gives a durable bonding between the grinding paper and the grinding plate, but which can be peeled clear when worn without leaving residue and allows a new grinding paper material to be attached easily.

Title: Profile-bar system for frame structures, vehicle bodies, rack systems, workshop and laboratory apparatuses or the like
IPC: F16M1/00
Filed: 1993-03-05
Abstract: The invention proposes a profile-bar system for frame structures, vehicle bodies, rack systems, workshop and laboratory apparatuses or the like which comprises profile bars (10, 11) which can be mounted on one another in a variable manner and exhibit, parallel to at least one outer surface, a groove duct (14) which is accessible via a longitudinal slot (13), runs in the longitudinal direction and is designed to receive groove nuts (21). Provided in the at least one outer surface is a moulded recess (12) which receives band-like mounting elements (19) which engage over the longitudinal slot (13) and are of corresponding cross-section. The mounting elements (19), intended for connecting the profile bars (10, 11) to one another and/or for connecting the profile bars (10, 11) to mounting surfaces, exhibit screw holes for mounting screws (20) which, in the mounted state, run through the longitudinal slot (13) and are anchored in groove nuts (21). Consequently, the mounting elements (19) serve not only to fasten the profile bars (10, 11), but, in the mounted state, they also cover the band-like moulded recesses. At the locations which are not covered by the mounting elements, said moulded recesses are covered by covering elements which are designed as reinforcement bands made from material which is stronger than the material of the profile bars and/or as plug-in covering bands, with the result that planar outer surfaces without elevations or depressions are formed, which surfaces reduce the risk of injury and improve the appearance. <IMAGE>

Title: Device for the dispensing of liquids into bottles, cans or similar containers
Inventor: WEIS WILHELM
IPC: G01F11/32
Filed: 1993-04-16
Abstract: In the case of a device for dispensing liquids into bottles, cans or similar containers, having at least one volumetric metering chamber which is connected via a controllable inlet valve to a container for supplying the liquid and via a controllable output valve to a filling nozzle, there are arranged in the metering chamber at least two sensors which respond to different filling levels, the upper sensor closing the inlet valve when the liquid reaches a certain height and the lower sensor closing the outlet valve when the liquid falls to a certain level. The vertical distance between the two sensors or their measuring points is therefore used to define the volume of liquid to be poured in a simple fashion. The structure of this device is simple and easy to understand and the device itself is easy to clean and can be converted without difficulty to dispense different volumes of liquid.

Title: Floor-mounted lathe with friction-roller drive for machining wheel sets with or without axle bearings or axle boxes
IPC: B23B5/28
Filed: 1993-06-21
Abstract: The application for patent rights comprises a lathe for machining wheel sets. Floor-mounted wheel lathes have clamping jaws for driving the wheel set. Clamping jaws of this type leave notches in the wheel set. To avoid such notches, friction rollers are used for driving the wheel sets. The use of friction rollers requires force equilibrium during turning. The apparatus according to the invention is characterised in that the lines of action of the top and/or bottom pressure rollers form an angle which is less than 180 degrees. Furthermore, the apparatus according to the invention is characterised in that it is possible to attach friction rollers to wheel lathes which were hitherto equipped with clamping-jaw drives.

Title: Method for coordinated digital transmission via a plurality of transmission paths
Inventor: HUBER JOHANNES PROF DR
IPC: H04L27/26
Filed: 1993-08-03
Abstract: A method for digital transmission via two or more transmission paths is indicated in which statistical dependencies between the interference which are superimposed on the individual received sub-signals are used to increase immunity to interference. This is done by forming estimated values for the interference in the next step using the interference determined in all transmission sub-systems for preceding steps and by subtracting these estimated interference values from the received signals. The method can be combined with known coordinated reception methods or can be used for direct minimisation of the residual interference. The coordinated transmission method can be implemented in a plurality of embodiments which are equivalent to one another, i.e. as interference prediction with cross-coupling between the transmission sub-systems, as a cross-coupled decorrelation of the interference with decision feedback equalisers and also as a generalised Tomlinson-Harashima precoding with cross-couplings at the transmitting and receiving ends. Further versions are represented by coordinated sequence estimation methods and status-reduced sequence estimation methods.
Patent DE-4326794-A1 (DE)
Title: Process and apparatus for printing flat individual objects
Inventor: ROHWETTER NORBERT
IPC: B41F17/24
Filed: 1993-08-10
Abstract: The invention relates to a process and to an apparatus for printing flat individual objects, e.g. CDs, by means of offset printing. In this arrangement, the surface which is to be printed, on the one hand, and the offset-litho cylinder, which is rolled on the object to be printed, are adjusted with respect to one another to achieve favourable pressing for the transfer of the printing image onto the object to be printed, in order thus to compensate for differences in thickness between the individual objects. If required, in the event of the mutual adjustment of the offset-litho cylinder and the surface which is to be printed, provision is further made to take account of the circumferential progression of the transfer surfaces located on the offset-litho cylinder if the latter deviates from the progression coaxial to the axis of rotation of the offset-litho cylinder. In the event of there being no object in the offset printing station, provision may be made for a replacement object in the form of a material web, onto which the printing image intended for the missing object is transferred by the offset-litho cylinder.
