Patent number: 10738996Abstract: A gas-fired burner adapted for use on a liquid fuel. A method for essentially smokeless start-up and steady state operation of a gas-fired burner on a liquid fuel. The apparatus integrates a catalytic liquid fuel reformer with a flame burner designed for operation on a gaseous fuel of high Wobbe Index, e.g., natural gas. The method involves reacting a mixture of a liquid fuel and oxidant in a catalytic reformer to obtain a gaseous reformate having a low Wobbe Index; and thereafter combusting the gaseous reformate, optionally augmented with liquid co-fuel and oxidant, in the gas-fired burner under diffusion flame conditions. The invention allows commercial gas-fired appliances to be operated on a liquid fuel, thereby offering advantages in logistics and camp operations.Type: GrantFiled: May 24, 2018Date of Patent: August 11, 2020Assignee: PRECISION COMBUSTION, INC.Inventors: Subir Roychoudhury, Richard Mastanduno, Bruce Crowder, David Lang Spence, Francesco Macri, Julian David Prada Bernal

Patent number: 9760375Abstract: A processor core includes even and odd execution slices each having a register file. The slices are each configured to perform operations specified in a first set of instructions on data from its respective register file, and together configured to perform operations specified in a second set of instructions on data stored across both register files. During utilization, the processor receives a first instruction of the first set specifying an operation, a target register, and a source register. Next, a second instruction upon which content of the source register depends is identified as being of the second set. In response, the first instruction is dispatched to the even slice. In accordance with the operation specified in the first instruction, the even slice uses content of the source register in its register file to produce a result. Copies of the result are written to the target register in both register files.Type: GrantFiled: September 9, 2014Date of Patent: September 12, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Maarten J.

Patent number: 9684749Abstract: A list of input registers and output registers for a circuit design are provided. The circuit design is modified by traversing output connections paths for each input register and replacing any register in the output connection paths with a wire unless the register is a listed output register. An initial total cycle time value for the modified circuit design is determined. A gate level description for the modified circuit design is obtained by a macro synthesis with the initial total cycle time value. The total cycle time value for the modified circuit design is then varied in order to determine the theoretical limit of the modified circuit design. This theoretical limit is realized when negative slacks are present in a macro synthesis of the modified circuit design for a given total cycle time value. Based on this theoretical limit, the minimum pipeline depth of the circuit design is determined.Type: GrantFiled: January 23, 2015Date of Patent: June 20, 2017Assignee: International Business Machines CorporationInventors: Maarten J.
