Patent GB-892750-A (GB)
Title: Incremental computors
Inventor: TOOTILL GEOFFREY COLIN
IPC: G06F7/66
Filed: 1959-12-04
Abstract: 892,750. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 19, 1961 [Dec. 4, 1959], No. 41361/59. Class 106 (1). An incremental computer comprises an integrand store, a variable of integration multiplier capable of multiplying two multi-bit pure number words, a remainder store, an adder for adding the product of the content of the integrand store and a multi-digit pure increment of a variable of integration to the content of the remainder store, the less significant part of the sum being put into the remainder store and the more significant part of the sum being made available for future use as a multi-digit pure increment of an integrand or of a variable of integration. As described, Fig. 2, a computer has one arithmetic unit time-shared by a plurality of integrators, whose integrands and remainders are stored sequentially in a delay line store 15. In order to obtain z=fydx, successive increments #z in the integral are calculated by calculating y. #x = #z+r, where r is a remainder term, the next step being to calculate the new value of y, y*=y+ #y, and then calculate y*. #x+r=z*+r* where r* is the new remainder. The quantities #z are used in other integrators either as increments (such as #y) to modify the integrands or as increments (such as #x) of the variables of integration. In operation, after the introduction of the initial value of the integrand, increments of the integrals (such as #z) appear on a line 61 in serial form and are applied to a store 7 (Fig. 4, not shown) whence they emerge on parallel channels 71 for application to selecting circuits 8, 90 where, under control of digits in selection words in stores 51, 52, increments #x for the variable and #y for the integrand are selected, respectively. An integrand from a store 10 is added in an adder 2 to the increment #y, the result being multiplied in a multiplier 3 (Fig. 3, not shown) by the increment #x, the product being fed to an adder 4 where it is added to the remainder from the previous step emerging from the store 15. The integral increment emerges, the more significant digits, #z, being routed to the store 7 and the less significant digits, constituting the new remainder, being routed via a delay line 11 to the store 15. The store 15 is used also to store integrand values emerging from the adder 2, these being routed back to the adder 2 to be added to the integrand increments. Specification 717,114 is referred to.

Title: Pattern recognition system
IPC: G06V30/194
Filed: 1968-08-30
Abstract: 1,219,858. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORP. 30 Aug., 1968 [14 Sept., 1967], No. 41420/68. Heading G4R. A pattern recognition system for recognizing an input pattern of a plurality of rows of binary digits, converts each row of the pattern into a form having a single bit of a selected binary value in a row of bits, applies this to a respective row of selectively preset bit memory units, and indicates the number of bits of the selected value which are applied to memory units storing the selected value. A light pen 12 is used to write a character on a 10Î6 photo-cell matrix 11, each 2x2 submatrix of which sets a corresponding trigger in input storage 16 via threshold logic 15 if at least two photo-cells of the sub-matrix are illuminated. Each 3-bit row of the 5-row input storage 16, treated as a binary number, is decoded to 1-out-of-8 form by AND-INVERTS at 17, the resulting 40 bits being applied to electronic templates 18-1 ... 18-n in common. During learning, the templates are enabled in turn, by "set" lines, to store the 40-bit patterns presented in SCRs, a plurality of patterns successively applied to a given template being ORed together. During recognition, each template receives the 40-bit input pattern and produces a voltage indicating the number of 1-bits the input and stored patterns have in common. Interconnected threshold devices D1 ... Dn light a lamp to indicate the largest voltage, except that this is prevented if a "blank interlock" circuit 21 detects no pattern (due to each row of input storage 16 storing 000 and there therefore being an output on the "zero" line of each group of 8 from decoder 17). Output may also be inhibited in response to particular input patterns, or in response to more than one output. The input storage 16 can also be fed from a speech decoding device.
