Abstract: 1,253,228. Ultrasonic inspection devices. AUTOMATION INDUSTRIES Inc. 27 Nov., 1968 [4 Dec., 1967], No. 56318/68. Heading H4D. An ultrasonic pulse-echo system is used to measure the dimensions of internal parts of the human eyeball. In the embodiment shown, a focused piezoelectric transmitting/receiving transducer 30 (or separate transmitting and receiving transducers) is coupled acoustically to the eye 12 by means of water-filled goggles 28. An optical system (not shown) provides a target on which the eye can fixate. Oscillator 54 provides timing signals which are frequency divided at 57 for triggering the acoustic pulse transmission. Each transmitted pulse gives rise to echoes from the front of the cornea 14 and from interfaces between cornea 14, anterior chamber 16, lens 18, vitreous body 20, retina 22, choroid 24 and sclera 26. These echoes are indicated as an A-scan display on a cathode-ray oscilloscope (C.R.O.) fed with a video signal from either receiver amplifier 58 or detector 72. To provide expanded scale traces respectively covering zones 106, 108, 110 in the eye, the video signal is fed to display channels A, B, C which, with a fourth channel D, are made operative in turn in respective successive periods of the acoustic pulse transmission. With channel A operative, the echo from the front of cornea 14 is selected by gate 80 and passes via gate A and pulse-shaper/amplifier 152 to trigger the C.R.O. sweep, whereby echoes in zone 106 of the eye will be displayed on a first trace. With channel B operative, the selected echo from the front of cornea 14 passes via gate B and delay 1 to trigger the sweep, whereby echoes in zone 108 are displayed on a second trace. Similarly, with channel C operative, the sweep triggering is delayed by delay 2 so that zone 110 is shown on a third trace. With channel D operative, timing signals obtained by frequency-division of oscillator 54 output are displayed on a fourth trace for calibration purposes. Different D.C. bias levels in the four channels ensure that the four traces are separated vertically on the C.R.O. screen. Delays 1 and 2 are variable and calibrated in terms of distance. Circuit details of gates A, B, C, D and 80, and of pulse shaper/ amplifier 152, are given.

Abstract: 1308253 Bird decoy P G GREGORY 9Feb 1972 [21 May 1971] 16261/71 Heading AIM  A bird decoy comprises a support 10 for the body of a dead bird, a pair of members 11, shown in plan in Fig. 1, movably mounted on support 10 for displaying the extended wings of the bird, and means for repeatedly imparting a flapping motion to members 11. Wing members 11 are pivotally mounted on opposite sides of the central support 10, itself supported on a detachable wire post 12 which can be staked in the ground, or on a tripod for increased height. Each wing member 11 is urged into the open position, indicated by the full lines by its respective coil return spring 28 and prevented from further outward pivoting by engagement of arm 26 with cross member 17, and can be swung into the extreme raised position, shown by the broken lines in Fig. 2 by rocking the arm 26 against the force of their respective return springs 28. Movement of the wing member 11 can be coordinated by employing a pull cord 31 possibly consisting of a single nylon thread secured as in Fig. 2 to loop 27 of the arm 26 on either side of support 10. The cord loop thus formed can be connected to another length of cord 32, secured to a free running ring 33 on the loop, and led through an eyelet 34 on post 12 to the hide. Post 12 has a screw thread top for detachable engagement with a corresponding bore 34 in rod 14 of support 10. In engaging the bore 34', the post 12 engages a hole 36 in sleeve 37 on rod 14, thereby maintaining the angular position of sleeve 37 and of a prong 38 fixed to a foot 39 on sleeve 37. In this position the prong 38 extends upwardly and forwardly but when freed by detaching post 12 can, by rotation of sleeve 37, be swung back to between side members 11 as indicated by the broken lines in Fig. 1. The decoy is prepared by letting member 11 open, and swinging prong 38 forwardly. The body of a freshly killed bird is placed on support 10. Each wing is held outstretched by pressing the underside of the wingbone on point 23 of the corresponding wing member 11. The neck is then pressed on prong 38 with its point entering just behind the beak. The head is held up by aligning hole 36 with bore 34', and threading in post 12. Wing members 11 can be worked together by alternately applying tension to, and relaxing pull cord 32. After use, post 12 is unscrewed allowing prong 38 to swing back between side portions 16. Then wing members 11 are swung across support 10 as indicated by the broken lines in Fig. 1, and retained in this position against springs 28. As the support may be made of stiff wire, it is both light and compact.

Abstract: 1309461 Measuring wheel unbalance electrically BENDIX WESTINGHOUSE LTD 28 May 1971 [18 June 1970 3 May 1971] 29755/70 and 12685/71 Heading G1N Apparatus for measuring the rotary unbalance of a vehicle wheel in situ comprises means for jacking up the vehicle, driving the wheel to a desired speed, measuring the cyclic unbalance face on the support and using the unbalance signals to trigger a stroboscopic light to illuminate the angular position of the unbalance. The suspension of the wheel to be tested is lowered on to a support 20 Fig. 4, which incorporates two piezoelectric crystals arranged to measure face or static unbalance on lead 21 and dynamic unbalance on lead 22. The wheel is driven by a spinner motor (not shown) to a high speed and allowed to run down. With switch 24 in the position shown, the static unbalance signal is fed via transistors 29, 31 and operational amplifier 37 to a phase locking circuit 40 which produces a square wave signal 8 Fig. 2, whose transitions coincide with the peaks of the fundamental of the unbalance signal 9. This square wave is differentiated at 64, 65 and the negative going pulses amplified by transistor 46 and fed via capacitor 80 and resistor 81 to a flasher circuit, whereby the wheel is illuminated when the unbalance mass is located on the horizontal through the axis. The flasher circuit is only open when the angular speed of the test wheel is within a frequency band selected by a frequency trip circuit 43, which also allows the unbalance measuring signal to be fed via capacitor 34 to charge capacitor 53 to the peak value, which is stored and shown on meter 56. The frequency band of circuit 43 may be adjustable. The meter 56 may be associated with a non-linear circuit to compensate for the variation of unbalance force with angular speed. The mechanical construction of the wheel support is described, with details of the incorporated piezocrystal transducers for measuring static and dynamic unbalances.

Abstract: 1312094 Endless conveyer systems for supplying work stations H W MARLOW 17 Nov 1971 [19 Nov 1970] 55003/70 Heading B8A Work containers 34 are conveyed on a conveyer belt 20 to a vacant one of a plurality of work surfaces 33. A vacancy at a surface 33 is indicated by a lamp (not shown) on an indicator panel by the action of a spring loaded auxiliary surface member 37. The latter also actuates, via a Bowden cable 61, the movement of an arm 45 (Figs. 5 and 6) to an operative position in which it is able to transmit movement from an operating rod 47. The arm 45 is connected to a plough member 39, and movement of the rod 47 against a return spring (60) (Fig. 18, not shown), causes the plough to be swung out into an operative (container discharging) position. The arm 39 is displaced back to its inoperative position by the action of the container engaging a portion 39c of the plough member, assisted by the gravity action of a rising-butt type hinge mechanism 40, 42 (Fig. 5). The operating rod 47 is actuated by the operator energizing a cylinder or solenoid 63 (Fig. 9, not shown). The rod 47 acts via pivoted rods 52, 53 (Fig. 5), the rod 52 having a pin 59 which is engageable with a forked portion of the arm 45 (when the latter is in its operative position). In a modification (Figs. 10-14, not shown), there are two operating rods (69), (69) respective to the plough members on each side of the conveyer. These are operated by the action of an electric moto (72) (Fig. 14, not shown). Each rod (69) is connected to the motor (72) via a respective rotating disc (76) having a notch (76a) for operation of a microswitch (84). This stops the motor (72) at the end of the travel of the rods (69), (69). In operation, when the operator sees from the panel that there are work stations without containers, he actuates the rod 47 (or rods (69), (69)), and this puts the respective plough members in operative position. He then loads the conveyer with the appropriate number of containers which are carried round and successively ploughed off at the vacant stations.
