Abstract: A data transmission system is described that connects a controller with drives in machine tools and production machines. The controller can be connected via an internal data bus with at least one internal drive, wherein the same data bus profiles are used for the internal data bus as for an external data bus. A user then sees the same data interface both for a central control topology and a drive-based control topology. This allows the user to readily interchange the two topologies and port existing applications to the various control topologies.

Abstract: A control arrangement for controlling web unwinding equipment used for feeding webs to a web-fed rotary printing machine stabilizes a swing roll used to tension the web at a central position via an integrator in a manner independent of the coefficient of friction. A proportional and differential element is connected in parallel with the integrator. The inputs of the integrator and the proportional and differential element are connected directly or indirectly to a swing-roll transmitter whose output is dependent on a position of the swing roll. The outputs of the integrator and the proportional and differential element act on an adder element. The output of the adder element acts directly or indirectly on a brake for braking the rotation of the wound roll.

Abstract: To sense misalignment between a clamping mandrel (1, 2) of a web roll carrier and a web center sleeve or tube (5) into which the mandrel is to be inserted, the mandrel is formed with a sensing head (8, 10, 11, 14) which is spring-loaded and projects by a distance (a) beyond an end face (9) of the tip portion (3) of the mandrel. Upon engagement of the sensing head, for example due to misalignment, with the sleeve or end face of the roll, the sensing head can resiliently slide into the mandrel and, at the same time, by coupling to an electrical switch pin (19), cause engagement of the switch pin with terminal rings (18, 19) located in the mandrel body, to cause reversal of movement of the mandrel from a forward or inserting movement (F) to reverse or retract (R) the mandrel, thus effectively and simply eliminating damage to the sleeve or tube and/or the roll of web material, and/or the mandrel.

Abstract: The process involves coating on both sides of an endless track of a base material consisting of inorganic fibers, preferably a glass fiber fleece, with aqueous ceramic slips, and drying of the coating. The base material with a weight per unit area of 30-200 g/m.sup.2 is coated with a slip, at least 500 g/m.sup.2, preferably 1000-2000 g/m.sup.2, without the use of an additional support, preferably on one side with a paste and on the other side with a glaze slip. The slips contain 3-20% by weight organic binders that decompose uniformly and without residue between 250.degree. and 600.degree. C. The dried, unfired veneers in free suspension may be coiled and uncoiled and subjected to continual decoration and firing processes.

Abstract: An ejector ring (18) surrounds an axially movable mandrel (6), on which a core sleeve or tube (19) for a paper web roll, for example a newsprint roll, can be supported. The ejector ring is resiliently supported on the holder structure, for example on a holder arm (1) and surrounds the mandrel, and is movable parallel to the mandrel. The structure is space-saving, provides for secure retention of the mandrel and is thereby capable of supporting heavy paper rolls, while providing for reliable stripping of core sleeves off the mandrel upon retraction of the mandrel into the holder structure, for example for exchange of a paper roll.

Abstract: To provide for controlled braking effort on a selected paper roll (5) from which a web (14) is applied to a utilization machine, and additionally for fast-stop or holding conditions, the roll is coupled to an operating disk brake (10) which receives braking pressure from a regulated pressure source. Additionally, rapid-stop brake calipers forming a rapid-stop brake (11) are applied to the disk, preferably having a higher braking friction coefficient, and controlled from the regulated pressure via a fluid disjunctive or OR-gate valve (42). A magnetic valve (36), controlled by a computer-controller (28), selectively switches the controlled fluid pressure through the OR-gate valve (42) only to the operating brake or to the fast-stop brake and, via a branch connection (46a), also to the operating brake.

Abstract: Sauce hollandaise, sauce bearnaise or similar fancy sauces, dressings, batters or soups are prepared by maintaining a supply of mixture of ingredients including butter or margarine, flour, milk, wine, vinegar, spices, salt, egg yolks and/or others in a state of readiness at a temperature of less than 50.degree. C., drawing by a pump a desired quantity of mixture from the supply and automatically mixing the withdrawn material with air in requisite quantities and simultaneously homogenizing the mixture of withdrawn material and air so that the ultimate product is of foamy consistency. Large quantities of prepared mixture can be stored in deep frozen condition, and batches of deep frozen mixture are defrosted as the need arises. The pump which draws mixture from the supply can be used to draw a stream of washing and/or rinsing liquid when the pump, its mixture supplying conduit and the homogenizing unit are to be cleaned.
