Abstract: 1,136,096. Magnetic tape recorders. NATIONAL RESEARCH DEVELOPMENT CORP. 9 Nov., 1966 [19 Nov., 1965], No. 49273/65. Heading G5R. A magnetic tape recorder includes two sets of recording heads L, U, the two sets being arranged to be energized alternately to record alternate blocks of digital signal data. The positions of the blocks of data in the order in which the data is written on the tape is designated by numerals 1 to 6 in Fig. 1. As shown, the heads U record blocks 1, 3 and 5 and the heads L record blocks 2, 4 and 6 so that the resultant block order is 2, 1, 4, 3, 6, 5. The spatial relationship between the two sets of heads L, U and the magnetic recording tape is controlled so that after block 1 is recorded by heads U, Fig. 1 (a) and before block 2 is recorded by heads L the distance between the two sets of recording heads in terms of tape length is (2B + G) where B denotes the length of a block of signal data and G the gap length between blocks, whereas after block 2 is recorded by heads L, Fig. 1(b), and before block 3 is recorded by heads U the distance between heads L and U in terms of tape length is 2B +3G. This variation in tape length is achieved by pulling a length 2G of recording tape past heads U whilst heads L are recording block 2. This tape movement may be obtained by a crank operated movable idler TM, Fig. 2, which may be moved to a position TM<SP>1</SP> to pull a length 2G of tape past the heads U when the tape is released from engagement with a capstan CU by releasing a pinch roller PU. Auxiliary data may be recorded at the end of a block of signal data by one set of heads whilst the immediately succeeding block of signal data is being recorded by the other set of recording heads. If the length of tape occupied by the auxiliary data is A the length of tape between the record heads L and U must vary by (2A + 2G) so that movement of idler TM between the recording of successive data blocks must be (A + G). The heads U are continuously energized to erase previously recorded matter before data recording takes place.

Title: Detection device for detecting outline features for image analysis systems
Inventor: FISHER COLIN
IPC: H04N5/14
Filed: 1968-05-01
Abstract: 1277014 Image analysis IMAGE ANALYSING COMPUTERS Ltd 29 April 1969 [1 May 1968] 49558/71 Divided out of 1277013 Heading H4F Relates to a detection device for use in an image analysis system employing line scanning arranged to detect boundary density variation and determine whether the scanning inspection spot is inside or outside a boundary feature, e.g. an annulus or ring as shown in Fig. 2 which does not have a different grey level within the boundary from that outside, and in which the video signal is converted into a two-state detected signal as shown in Fig. 2. The operation of the device relies upon the fact that features of this type have asymmetrical boundary density profiles, i.e. when the scanning spot enters or leaves the boundary feature the resulting video signal has different emplitudes at equal intervals of time t (e.g. one picture element) on each side of the peak b, Fig. 2. In a first embodiment, Fig. 1, the video signal is fed through two delays 40 to form a first (t) and a second (2t) delayed video signal. The first delayed (t) video signal is released by gates 42 and 44 only when it is greater than the undelayed and second delayed video signals (logic units 48 and 46), i.e. the video signal from B only passes through gates 42 and 44 when the signal at B corresponds to a peak b. Two logic units 50 and 52 compare the signals at A and C to determine which is the greater and their outputs together with the signal from gate 44 are supplied to AND gates 54, 56, the outputs of which control a bi-stable circuit 58. When the signal amplitude at C is greater than that at A and the amplitude at B exceeds that at both A and C circuit 58 is " Set," and when the amplitude at A exceeds that at C and the amplitude at B exceeds that at both A and C circuit 58 is " Reset." In a second embodiment, Figs. 3 and 4, a ring having a thickness of one picture element is detected, five line scans each divided into five picture elements being shown. The input video signal is supplied to a delay matrix as shown in Fig. 3 which includes one scan line period delays 67 and picture element delays 69 and 40. The signals from the delays in advance of that from which the signal is supplied to gates 44 and 42 (as in Fig. 1) are weighted in accordance with their distances from b and added in circuit 71 to form an x signal and similarly the outputs from the following delays are added in circuit 72 to form a y signal. It can be shown mathematically that the sum of the picture elements to the right of the middle column of picture elements will always exceed the sum of those to the left of this column as the scanning spot enters the boundary feature whilst the reverse is so as the scanning spot leaves the boundary feature. Two comparison circuits 74 and 76 determine whether x or y is the greater and operate in conjunction with the detected boundary position to set and reset a bi-stable circuit 58 by means of AND gates 56 and 54 in the same way as in Fig. 1.
