Patent number: 4154604Abstract: Additives in the form of a wire-like object are introduced through a tube into the interior of molten metal bath. The wire in the tube is surrounded by a pressurized gas which prevents metal from entering the tube. Since the tube extends close to the bottom of the bath, the additives melt near that bottom and are distributed in the bath through convective flow.Type: GrantFiled: July 21, 1977Date of Patent: May 15, 1979Assignee: Mannesmann AktiengesellschaftInventors: Hans Gruner, Hans Schrewe, Fritz P. Pleschiutschnigg

Patent number: 4104720Abstract: There is disclosed a data processing system which employs parallel processors (PP's or P--P's) that are interfaced to the CPU, and which derive their control from microinstructions stored in an extension to the CPU microcode structure. This extension forms part of the CPU/PP interface. The P--P's increase speed of operation of the data processing system in which they are employed by operating synchronously and simultaneously with the CPU when called upon by CPU microcode structure to execute particular algorithms.Type: GrantFiled: November 29, 1976Date of Patent: August 1, 1978Assignee: Data General CorporationInventor: Ronald Hans Gruner

Patent number: 4100959Abstract: Molten steel pouring from a ladle into a tundish is surrounded by a vessel which is pressurized to maintain an excess pressure of an inert gas and/or a gas or vapor of a material that treats the steel, e.g., for deoxidizing, desulfurizing and/or other cleansing action. The excess pressure per se inhibits any reoxidation. Reactant material is fed to the chamber at a rate to maintain the excess pressure and/or to ensure sufficient presence of reacting material commensurate with the amount of steel passing through.Type: GrantFiled: February 22, 1977Date of Patent: July 18, 1978Assignee: Mannesmann AktiengesellschaftInventors: Hans Gruner, Hans Schrewe, Gerd Diederich, Claus-Dieter Haufe, Fritz-Peter Pleschiutschnigg

Patent number: 4042972Abstract: A microprogrammed processor in which control signals for data paths, the ALU function, the shifter and all other control signals are derived from the current microprogram control word which is normally periodically clocked into a ROM buffer. The processor provides for microbranching capability with and/or without a test, testing capabilities including direct addressing with simultaneous temporary address storage capability for future recall, and selective testing of computer instruction bits for decoding to address the next micro-instruction. Additional capabilities provide for flexible access to the micro-code instruction control store through a ROM address multiplexer which allows for selection of at least one of four possible micro-instruction addresses determined by micro-code control decode logic.Type: GrantFiled: September 25, 1974Date of Patent: August 16, 1977Assignee: Data General CorporationInventors: Ronald Hans Gruner, Carl Justin Alsing

Patent number: 4024959Abstract: A handling device has a flexible gripper having a drive associated with one movement of the gripper and including a member which is caused to move against an adjustable force when an actuating force determined by the adjustable force acts on the gripper, and a switch element operable by the displaced member and serving to control at least one movement of the handling device and/or the gripper.Type: GrantFiled: November 11, 1974Date of Patent: May 24, 1977Inventor: Hans Gruner

Patent number: 4019560Abstract: Continuously cast ingots are spray-cooled by a fanned-out flow of water which has been accellerated by pressurized air with an original nozzle direction parallel to the surface of the ingot and transversely to the direction of ingot withdrawal. The arrangement avoids cooling impediment on account of the Leiden frost phenomenon.Type: GrantFiled: September 18, 1975Date of Patent: April 26, 1977Assignee: Mannesmann AktiengesellschaftInventors: Hans Gruner, Gerd Diederich, Hans Butz, Peter Wahls, Engelbert Weins

Patent number: 4006995Abstract: A drill for use in boring machines has a tool holder with two cutter bars having cutters projecting radially therefrom. The cutter bars are movably mounted in a radial direction in a recess passing through the tool holder. The tool holder includes a base part and walls projecting therefrom forming the recess therebetween. The cutter bars are arranged in this recess in end-to-end relation and are of a width substantially equal to the width of the recess. The base is provided with two slots therein communicating with the recess, the slots being offset with respect to each other and each extending from the outside of the base in a direction substantially parallel to the length of the recess up approximately to the central axis. Bolts engaged in the parts on opposite sides of the slots can be tightened to deform the walls of the recess so as to clamp the cutter bars therebetween.Type: GrantFiled: March 10, 1975Date of Patent: February 8, 1977Inventor: Hans Gruner

Patent number: 3990052Abstract: A microprogrammed processor having a versatile hardware and data path configuration in which control signals for data paths, the ALU function, the shifter and all other control signals are derived from the current microprogram control word which is normally periodically clocked into a ROM buffer. Included are capabilities for effective addressing, incrementing the program counter and computer instruction skips, all while the instruction register is being loaded from memory by direct connection of selected bits of the memory bus to the ROM buffer to derive a micro-instruction. Also included is a conditional skip condition allowing the processor to skip the next instruction by testing selected bits of the instruction register which manipulates the micro-code for this purpose. Another capability is that of hardware structuring to readily accommodate WCS. Other capabilities provide for bit and byte manipulation, allowing the micro-instruction to readily load constants into the ALU, and for marking purposes.Type: GrantFiled: September 25, 1974Date of Patent: November 2, 1976Assignee: Data General CorporationInventor: Ronald Hans Gruner

Patent number: 3982795Abstract: A compressed air supply system, including a compressor and a pressure regulator, is coupled to a multi-circuit brake valve. Each circuit of this multi-circuit brake valve includes a double valve and an associated safety valve positioned in coaxial relationship therewith. The safety valves are each coupled to an associated supply tank and are coupled in common to the compressed air supply system by a spring-loaded needle valve.Type: GrantFiled: December 22, 1975Date of Patent: September 28, 1976Assignee: Graubremse GmbHInventor: Hans Gruner
