Title: Method of and apparatus for recognizing characters
Inventor: SCHUMANN HEINZ
IPC: G06V30/146
Filed: 1969-03-18
Abstract: 1,223,365. Character recognition. ELEKTRONISCHE RECHENMASCHINEN WISSENSCHAFTLICHER INDUSTRIEBETRIEB. KARL-MARX-STADT. 18 March, 1969, No. 14186/69. Heading G4R. Character recognition is performed by fullyparallel sensing of the character using a plurality of photo-cells disposed in a sensing field, and reducing by stages the electrical sensing field formed by their outputs, the information for one element of a following field in this reduction being taken from the element similarly situated in the preceding field or from the elements surrounding this element, this transfer of information being controlled by the information contained in the marginal elements of the preceding field in such a way as to retain a sequence character-blank-character starting at one corner of the preceding field, if the sequence occurs. At a given stage in the reduction, i.e. in going from a given field to its successor field (which is smaller), each element of the successor field receives the bit (black or white) of the corresponding element in the given field, unless there is any black bit in the uppermost row, lowermost row, leftmost column or rightmost column of elements of the given field, when the elements are displaced by one position as and if necessary to centre the pattern, adjacent elements being ORed together, as necessary to conform to the smaller size of the successor field, as near to the field margin as possible consistent with not destroying the sequences BWB where B is a black character bit and W is a white bit. After three reduction stages, the final field is decoded to identify the character. A series of arrays of logic circuits may be used, one array per stage in the reduction, or two arrays may be used with transfer back and forth, or a two-dimensional shift register permitting shift in four directions may be used with selective inhibition of shift in selected areas.

Abstract: 576,421. Stereoscopic viewing devices. FRANKLIN, A. P. Aug. 31, 1943, Nos. 14191/43, 17180/43, 17383/43, 18472/43 and 3592/44. [Class 97 (i)] An apparatus for viewing stereoscopic pictures at a distance comprises a viewing device on an adjustable support, the support allowing movement of the viewing device within limits, but maintaining the device so that a line joining the centres of the eyepieces is always in a plane passing through the centres of the pair of pictures and positively restraining movement out of that plane. As shown applied to a cinema theatre, the device has a body 2 flared at one end and with a central partition 6 divided at the viewing end into two flaps 60 adjustable to suit the distance apart of the viewer's eyes, the flared end of the body having two adjustable shutters 14 to cut out extraneous light. Two interchangeable and laterally adjustable prisms 10, which may be rotatably mounted, are fitted on either side of the partition and the whole device is mounted on an adjustable support which, while preventing rotation out of a plane passing through the centres of the pictures of a line joining the centres of the prisms, allows the device to be comfortably, adjusted before the eyes. The viewing end may have an adjustable tube for each eye instead of the flaps 60 and one prism only may be used (Fig. 7, not shown). In a modification, Fig. 1 of Provisional Specification 18472/43 (not shown), the flared end of the body is replaced by two adjustable conical tubes, in the narrow end of which are mounted the prisms. Figs. 4 and 5 of Provisional Specification 3592/44 (not shown), illustrate a method of supporting the device from the back of the seat in front of the viewer. Lenses of small magnification may be incorporated in the device and the prisms may be replaced by colour filters or filters for polarised light. The prisms may be removed and the device adjusted for viewing without stereoscopic effect. The only adjustment required by the viewer is that for the distance apart of the eyes, all the other adjustments being pre-set. The device may be mounted on a portable stand for viewing stereoscopic television pictures.

Abstract: 1,202,674. Data processing; gated counters. INTERNATIONAL BUSINESS MACHINES CORP. 19 March, 1969 [1 April, 1968], No. 14319/69. Heading G4A. A data processing unit comprises a plurality of buffers in the input to arithmetic circuitry for receiving operand data strings, and means to feed the operand(s) in the highest-priority completed string from its buffer to the arithmetic circuitry. A two-stage floating-point adder receives a pair of operands from any of 3 buffers (pairs of registers) when a START signal respective to the buffer is produced. When a buffer is to be loaded, a respective SELect signal is produced to set a coded representation of the buffer identity into the lowest empty position (pair of bi-stables) of a stack as indicated by a counter, the SELect signal then incrementing the counter. When a buffer is completely loaded (which may take a plurality of memory accesses), it produces a respective Unit Full signal. A priority network determines the buffer identity furthest down the stack for which the Unit Full signal is present, and provided the adder is not full, a START bi-stable respective to this buffer is set to produce its START signal and reset the stack position containing the buffer identity. Buffer identities automatically move down the stack to fill up empty positions, via auxiliary pairs of bi-stables. After a buffer has been freed, a respective ACcePT signal decrements the counter and resets the respective START bi-stable. Production of SELect signals is inhibited when the counter indicates the stack is full. Counter (Fig. 7).-An input at any of SEL 1-3 produces a signal INC and an input at any of ACPT 1-3 produces a signal DEC, except that if both would thus be produced simultaneously, neither is produced. A signal I/D is produced if either INC or DEC is. INC and DEC respectively increment and decrement the binary counter which has two counting bistables PH<SP>11</SP>Cl, PH<SP>11</SP>C2, the count in which is periodically (by clock pulses t 6 ) copied into auxiliary bi-stables PHC11, PHC22 which, together with signals INC, DEC, I/D, control input gates 101-107 of the counting bi-stables PH<SP>11</SP>C1, PH<SP>11</SP>C2, the latter being enabled to respond to the gates by coincidence of I/D with clock pulses t 11  at AND 108.

Abstract: 1343494 Labelling machine XEROX CORP 12 May 1971 [15 May 1970] 14449/71 Heading B8F [Also in Division B6] A labelling machine comprises a label transfer wheel 17 for labelling articles and a label accumulator 21 which holds a supply of labels 11, separated from sheet 20, prior to transfer to wheel 17 in order that the supplying means and transfer wheel need not be exactly synchronized. The labels are detached a row at a time from the sheet, previously slit lengthwise by slitters 63, by guillotine 40, and fed to the accumulator on the upper run of endless belt 35, moving around pulleys 38, 39. A stripping finger 34 detaches the labels from pulley 38 and they collect, standing on edge on the base 27, in the accumulator. A pick-off wheel 22 removes the labels through gap 25, between base and rear wall 28, to shoe 30 of transfer wheel 17. Vacuum acts through slots in belt 35, the pulley 38, wheel 22 and shoe 30 to hold the labels against the moving parts. Articles such as envelopes, are fed by a conveyer between the transfer wheel 17 and a pressure roll (not shown). The spacing between the wheel 17 and the pressure roll may be adjustable to accommodate articles of different thicknesses. For coating the underside of the labels with adhesive a glue dispensing roller is mounted to the left of wheel 17, as seen in Fig. 2. Alternatively label information only may be transferred to the articles, for instance wax impressions carried on the label may be transferred by including suitable heating means in wheel 17.
