High solids adhesives with low viscosity and a high flash point are p...

A binary multiplier circuit wherein the product is expressed in coded form as soon as the linear (or non-coded) product is produced. When a twelve-bit binary number in a register 10 is multiplied by another twelve-bit binary number in a register 12 a twenty-four bit binary number is produced in an accumulator register 15. The twenty-four bit product can be coded into an unsigned seven-bit binary n...
