Patent GB-1033533-A (GB)
Title: Improvements in and relating to character and the like electric signal recognition apparatus
IPC: G06K9/64
Filed: 1963-01-15
Abstract: 1,033,533. Automatic character reading. PHILCO CORPORATION. Jan. 15, 1963 [Jan. 15, 1962], No. 1768/63. Heading G4R. In character recognition apparatus the character is scanned and the resulting signals are entered serially into a matrix of seriesconnected shift-register elements so that the pattern moves in column by column from one side, circulating vertically between each step, resistive correlation networks being connected to the shift register stages, having resistors weighted so that the networks recognise particular selections of signals and characters are identified by the response of a combination of networks. The character 20 is scanned by the flying spot of CRT. 24, reflected light being received by a photo-cell 46, and the signals generated being shaped and sampled at 52 to form a series of evenly spaced " black " or " white signals representing the character which are entered into the shift register matrix 56. The stages of the shift register are transistor flip-flops and they are connected in a chain by short delay lines. Set and reset outputs from the stages are connected through amplifiers 112a-112i to the individual resistors of the various networks 128, 133, 137 &c. The networks are designed to respond to a group of characters. For example the network of Fig. 5A (not shown) has weighted positive connections to the several black 4 areas and weighted negative connections to white areas. It responds to letter Z and perhaps also to w, e, r, u, o, a, x, c, v and n. The network of Fig. 5B (not shown) responds to z and perhaps to s and m. As the pattern enters the shift register the correlation networks give responses in the form of fluctuating waveforms which, in the case of a recognition, reaches a predetermined threshold level at the instant that the pattern is in the registered position in the matrix. Transistors 152, Fig. 4 (not shown), act as threshold circuits, the level being set by resistor 153. Where the response signal exceeds the threshold the transistor 152 conducts, setting transistor flip-flop 155, 154. If the three networks 128, 133, 137 are to be combined to identify a particular character, they are connected as shown. When all three circuits have responded a negative signal is provided at 160 identifying a particular character. The circuits 128, 133, 137 may be combined with others to form groups for identifying other characters.

IPC: G01C3/16
Filed: 1929-01-22
Abstract: 325,956. Barr & Stroud, Ltd., and French, J. W. Jan. 22, 1929. Range - finders. - In stereoscopic observation instruments having in the field of view a stereoscopic image of the target which serves as a reference image to which a second stereoscopic image of the target is referred, the separation of the image may be variable in direction and/or magnitude and the magnification of the two images may be unequal. To form one of the images, rays from the target are reflected by prisms 53, 54 along the tube 52. On one side the rays pass through objective 9, prism 59, lens system 11, 61, 63 and 12 to the eye. A movable prism between lens 9 and prism 59 serves to change the apparent stereoscopic distance of the image. A corresponding prism may be present on the other side of the instrument which in other respects is exactly similar. The reference image, formed by rays through lenses 64, 65 may be deviated by prism 30, which may be displaced along the direction of the light path to vary the linear separation of the images and may be rotated to vary their angular separation. The reference image may also be formed as shown in Fig. 7 using a single lens 40. One half of the beam enters the prism 33 and after reflection by surfaces 36, 37 passes through the semi-silvered surface 4; the other half passes through prism 32 and a stereoscopic image is formed by the two beams.
