Patent number: 10202712Abstract: The present invention relates to a process for producing dyed polyester fibers (C) from a terephthalate polyester (A), at least one polyester-containing additive (B) and optionally at least one component (G). The polyester-containing additive is obtainable by condensation of the monomers of an aliphatic 1,?-diol, of an aliphatic 1,?-dicarboxylic acid and of an aromatic 1,?-dicarboxylic acid. Optionally, chain extenders (V) are also used in the production of the polyester-containing additive (B). For fiber production, the components (A), (B) and optionally (G) are mixed, melted in an extruder and extruded through spinneret dies. These polyester fibers (C) are preferably used in the production of dyed textile fabrics (F).Type: GrantFiled: July 27, 2010Date of Patent: February 12, 2019Assignee: BASF SEInventors: Pia Baum, Klaus Scheuermann

Patent number: 4396871Abstract: The invention relates to an arrangement for digital brightness control of lamps or groups of lamps in control channels particularly for use in planetarium illumination comprising in each control channel a programmable counter, a bistable flip-flop, and a power control stage. Each control channel is connected to a mains synchronizing stage and to a pulse generator. The control channel produces a mains synchronous pulse sequence frequency the pulse width repitition ratio of which depends on the selected division ratio of the programmable counter. The inventional solution offers a simple digital and controllable circuit arrangement for control of thyristors or triacs or transistors which, in turn, control the brightness of lamps or lamp groups.Type: GrantFiled: February 19, 1981Date of Patent: August 2, 1983Inventor: Klaus Scheuermann

Patent number: 3987819Abstract: A mixing valve system for hot and cold liquids. A selectable temperature is controlled by mixing suitable parts of hot and cold liquid controlled by a plurality of disks having holes therethrough oriented in a particular manner to achieve the desired result. The system is composed of three stationary disks and two rotatable disks. Each rotatable disk is sandwiched between different pairs of the stationary disks. One rotatable disk controls the volume of flow and the other rotatable disk controls the amount of hot liquid that is to be mixed with the cold liquid.Type: GrantFiled: March 17, 1975Date of Patent: October 26, 1976Inventor: Klaus Scheuermann
