Title: Improvements in form recognition method and system therefor
IPC: G06V30/144
Filed: 1958-08-20
Abstract: 885,545. Form recognition systems. GENERAL ELECTRIC CO. Aug. 20, 1958 [Sept. 30, 1957], No. 26793/58. Addition to 858,002. Class 40(3). A curve or form recognition system includes an electronic curve follower as described and claimed in the parent Specification wherein signals representative of the orthogonal components of the curve being followed are generated, these signals being converted to transfer the origin of the coordinate system to a unique point and then further converted into a polar signal which is a polar representation of the curve with its origin at the unique point, a signal which represents an invariant function of the curve being derived from the polar signal. In Fig. 1, a curve follower 10 derives from a curve 13 orthogonal co-ordinates which are applied to filters each comprised by a capacitor and resistance 14, 15 and 16, 17 respectively, to remove the D.C. component whereby the signals are converted into signals representing co-ordinates referred to the centroid of the arc of the curve 13 which are applied to balanced modulators 18, 19 and adder 20 to obtain the signal #sin (wt + #) which is a polar representation of the curve 13 having its origin at the centroid of the arc. The signal #sin (wt + #) is fed to a peak detector 24 to obtain a signal # which is an invariant function of the curve 13 and which is in turn fed to a delay 25, such as an audio delay line to obtain a signal # 2  from which invariant functions # 2 -# 1  and # 1 /# 2  can be de-   rived by a subtraction circuit 26 and divider circuit 28 respectively, fed by the delayed and undelayed signal #. The signals # and # 2 -# 1  can be divided by a signal S proportional to the total arc length of the curve 13 to obtain further invariant functions of the curve 13. The signal #sin (wt + #) may be applied to a frequency modulator detector 29 the output of which is an invariant function, d#/dS, which can be multiplied by the total arc length S in a multiplier 30 to derive a further invariant function. The signal #sin (wt + #) may be fed to a delay 31 and to a limiter 33 to provide inputs for a phase detector having an output proportional to the invariant function sin ## or cos ##. The signal #sin (wt + #) may be applied via a limiter 34 to a phase discriminator 35 to which is fed a signal Vcos (wt + #) obtained from the curve follower where # is the direction angle of the curve 13. The output of the phase discriminator 35 is the invariant function sinα or cosα where α = #-#. Recognition of the curve 13 by means of the above invariant functions is accomplished by displaying an invariant function on a cathode ray tube covered by a stencil cut to the proper shape. A photocell and pulse width discriminator yield a signal when the waveform matches the stencil. Specifications 873,156 and 873,157 also are referred to.

Abstract: 744,560. Washing-machines. CLUBB & CO. PTY., Ltd., A. M. Oct. 1, 1953 [Nov. 19, 1952], No. 26984/53. Class 138 (2). [Also in Group XXIV] A washing-machine comprises a hollow post 5 secured near its lower end to a base 8, a liquid container 13 mounted by its floor 12 on the upper end of the post 5, a perforated drum 25 within the container, a tube 23 extending through the upper end of the post 5 and an aperture 37 in the floor 38 of the drum, a first sleeve 24 surrounding the tube 23 from the container floor 12 to near the upper end of the tube, a second sleeve 29 surrounding the first sleeve and the tube and connected to the upper end of the tube and to the drum floor 38, means for continuously rotating and for oscillating the tube 23 and means for selectively connecting the tube 23 to the rotary or oscillatory means. The drum 25 has internal agitating means in the form of six horizontal vaned legs 30 projecting radially from the sleeve 29, and a series of wedgeshaped radial vanes 85 formed in a strip of aluminium secured around the interior wall of the drum. The drum 25 is oscillated for washing and rotated continuously for spin drying, the change-over being effected by means of a control rod 53. A knob 63 on the rod 53 has a projection 64 with a chamfered edge adapted to engage a similarly chamfered cam nut 65 so that on rotation of the knob 63 the rod 53 moves axially, being biased downwardly by a spring 60. As the rod 53 moves downwardly a tapered portion 54 thereof forces balls 56 outwardly so as to expand a split collar 47 and establish a driving connection between the collar 47 and a sleeve 46 in a pulley 42. The collar 47 is split at 51 (Fig. 4) and partially slotted at 52, 52. It has a wear--resistant outer surface 49 and is keyed to the tube 23 at 48. The balls 56 are located in openings 55 in the walls of the tube 23. Continuous rotation is thus imparted to the drum 25 from a motor 59 through pulley 42, sleeve 46, collar 47, balls 56 and tube 23. To oscillate the drum the knob 63 is turned so that the rod 53 moves upwardly thereby freeing the clutch means 46, 47 and allowing a pin 78 carried by an arm 76 on the rod 53 to enter one of a number of spaced holes 82 in a crank arm 74 rotatably mounted on the tube 23. The crank arm 74 is oscillated by means of a link arm 75 and crank pin 72 on a pulley 71 which is connected through pulleys 70, 67, 43 and belts to the pulley 42. The locking pin 78 is biased upwardly by a spring 79 and is slidable in a bore in a collar 45 keyed to the tube 23. A squared aperture in the upper end of the sleeve 29 fits over a square section end 27 of the tube 23, the upper end of the sleeve 29 being slotted so as to grip the end 27 when a nut 36 is screwed down. The post 5 acts as a vibration damper during spin drying and this is assisted by a tie rod 18 attached to the container floor 12 and base 8.
