Patent GB-1395991-A (GB)
Title: Electornic arrangement for the multiplication of a binary- coded number in a system having an even-numbered radix greater than 2 with a factor equal to half the radix of siad system of numbers
Inventor: MELCHER D
IPC: H03M7/14
Filed: 1972-08-23
Abstract: 1395991 Multiplying WIRTH GALLO & CO 23 Aug 1972 [24 May 1972] 39212/72 Heading G4A  A number in a system having an even number radix b of a form z = #a i b<SP>i</SP> each digit in the radix being in binary coded form is multiplied by b/2 to derive a number c = #c i b<SP>i</SP>. The coefficients c i  are of the form c i  = p i  + u i-1  where (1) if a i  is even pi = 0 and if a i  is odd p i  = b/2 and (2) u i  is determined by division of a i  by 2 (rounded down). In the embodiment described for a radix of 10 in which the bits of the numbers z are fed in parallel coded serial form on lines 1-4, the terms p i  are derived by connecting the least significant bit of each digit to the 2<SP>0</SP> and 2<SP>2</SP> terms of the first input of adder 13 so that 0 or 5 is applied to the adder in dependence on whether the coefficient a i  is even or odd. The terms u i-1  are derived by delaying by one clock pulse (in bi-stables 14, 15, 16) the three most significant bits of each digit and then dividing them by 2 by connecting them to the three least significant inputs of the second input channel of the adder 13. The adder output 21-24 gives the required product.

A second diaphragm 10 is provided above the bimetallic diaphragm 11 and operates a transmission member 28 which controls contact springs 30. The diaphragm 11 actuates a transmission member 25 for controlling contact springs 27. In operation, the pressure developed in the chamber 20 due to the water entering via the passage 21 causes the diaphragm 10 to rise and the supply circuit to the heating coil 6 to be completed through springs 30, contacts 31, 31<SP>1</SP> and springs 27. Should excess pressure due to steam be generated in the channels 5, 5<SP>1</SP> and chamber 7, the diaphragm 11 is pushed upwards and the circuit is broken at contacts 31<SP>1</SP>. The diaphragm 11 also causes the circuit to be broken if the water in the chamber 7 is overheated.
