Title: Article handling apparatus
IPC: B65B35/36
Filed: 1972-11-10
Abstract: 1398550 Conveying and stacking tea bags and like packets; delivering flat articles DELAMERE & WILLIAMS CO Ltd 10 Nov 1972 [12 Nov 1971] 52082/72 Headings B8A B8R and B8C Tea bags T (Fig. 1), being conveyed on edge, in line, are successively picked up by grippers 38 as the latter are carried along the bottom run of an endless conveyer. The grippers, after they close on a tea bag, are rotated through 90 degrees and are displaced laterally. The lateral movement is in opposite directions for each alternate gripper. This produces two side-by-side stacks of tea bags. Each gripper comprises two jaws mounted on pivot pins 40, fixed on a plunger 42. The plunger is rotatably mounted in a cylinder 46 carried on a bar 36 slidable relative to a bridge member 26. The ends of the latter are connected to respective endless conveyer chains. Each bar 36 has a cam follower roller 82 which runs between a pair of cam rails 86. Alternate bars 36 have their cam follower rollers 82 at opposite ends, there being an appropriate pair of rails 86 on each side of the conveyer. The pairs of rails 36 converge in the direction of travel of the conveyer, away from the point of tea bag pick-up. This results in the grippers 38 (which are all initially disposed centrally of the conveyer) being displaced alternately to each side of the conveyer. Due to links 58 (Fig. 4), coupled between each gripper plunger 42 and a pivot point on the associated bridge 26, the grippers rotate through 90 degrees as they are displaced laterally. Thus the tea bags are moved rotationally and laterally into positions for forming two side-by-side rows, are are released into pockets of a corresponding conveyer as shown at the l.h. side of Fig. 1. The grippers 38 are urged to a gripping position by the action of a spring 74 which urges a plunger 62 radially inwardly of the conveyer. On its outer end, the plunger 62 is formed with rack teeth which drive the jaws of the gripper. Prior to pick-up of the tea bags, and at the region of release (at the l.h. side of Fig. 1), the grippers are opened by the action of cam tracks 90 which engage a follower 79 carried on each plunger 62. Additional cam members 96, 96, may be projected so as to release a defective bag. The bags are scanned by sensors (S1) (S2) (Fig. 8, not shown). These control a valve (V) in an air pressure line connected to a motor (MC) (Fig. 7, not shown), which motivates the members 96. The followers 79 are lubricated by a pad 118.

Title: Electro-discharge machining
IPC: B23H1/02
Filed: 1971-11-15
Abstract: 1330418 Electro-erosion CINCINNATI MILACRON Inc 15 Nov 1971 [4 Dec 1970] 52977/71 Heading B3V [Also in Divisions G3 H2 and H3] Arcing in a spark erosion machining gap 14 is detected and eliminated by detecting the absence of a noise signal across the gap 14 during a spark discharge and reducing the energy level of the succeeding spark discharges. During a normal machining discharge, a high frequency noise signal is separated from the discharge signal by capacitors 52, 54, Fig. 4a, of a detector circuit 18 connected across the gap 14. The signal is fed via a transistor 61 to transistors 62, 64 and if several cycles of noise signals occur, a capacitor 72 is allowed to charge causing a transistor 68 to be switched on. During ionization of the gap 14 the capacitor 72 can discharge through a transistor 74 switched on by a Zener diode 76 having a break down voltage between the normal machining voltage and break down voltage of the gap 14. If a low voltage discharge occurs, a transistor 80 is switched on by a Zener diode 78 causing the transistor 74 to be switched on thereby preventing charging of the capacitor 72 and noise detection during that discharge. The switching of transistor 68 turns on transistor 70 which in turn switches on transistors (82, 84) (Fig. 4b, not shown) the former of which is connected to a photon coupled isolator (86), which switches via a Zener diode (85) a transistor (87) to provide a discharge path for a capacitor (91). When an arc occurs in the gap 14, the resistance of the receiver (90) of the isolator (86) rises to a value, after several machining pulses, such that the Zener diode (85) switches off the transistor (87) to allow the capacitor (91) to charge. As a result, an output from the circuit 18 is produced via Zener diode (92), transistors (94, 96) and photon coupled diode (98) and is fed to a Schmitt trigger 30 comprising transistors (104, 106). The output from the trigger 30 is fed via an amplifier 32 comprising a transistor (108) to a multivibrator 34 comprising Darling- ton pairs (122, 124) (Fig. 4c, not shown) and switches 36, 38 comprising transistors (110a, 110b, 112) which modify the on and off times of the machining pulses as determined by potentiometers (114, 116). The trigger 30 is returned after a predetermined time to its original state by the multivibrator 34 causing the pulse sequence to return to its original level. If a continuous output from the circuit 18 occurs, a time delay 42 is energized causing the machining pulses to be terminated.

Abstract: 1,254,564. Colour video signal recording and reproduction. SONY CORP. 11 Nov., 1968 [13 Nov., 1967], No, 53303/68. Heading H4F. In a recording and reproduction apparatus a colour video signal Ec, Fig. 1, is separated into its luminance and chrominance components, the frequency band of the latter component lying within that of the former, the luminance signal Ey is frequency modulated on to a carrier in a modulator circuit 4 and the frequency of the chrominance signal Es is converted so that the chrominance signal frequency band lies at least predominantly below that of the frequency-modulated luminance signal. A pilot signal Fp having a frequency band lower than that of the frequency-converted chrominance signal Es<SP>1</SP> is generated and added firstly to the signal Es<SP>1</SP> in a mixer 13 and then to the frequency-modulated luminance signal Ey<SP>1</SP> in a signal synthesizer 15. The resulting signal is recorded on magnetic tape 17 by a head 16. Reproduction is effected via a head 21, Fig. 2, and a series of filters 23, 26, 28 then separates the recorded signal into its components Ey<SP>1</SP>, Es<SP>1</SP> and Fp. The luminance signal is demodulated at 25 and the chrominance signal is restored to its original frequency band at 30. In addition the amplitude of the chrominance signal is controlled at 27 by a signal obtained from a circuit 29 which provides a D.C. output dependent upon the amplitude of the pilot signal Fp. The demodulated luminance signal Ey and frequency-restored chrominance signal Es are finally combined in a synthesizer 35 to reproduce the colour video signal Ec<SP>1</SP>. In the N.T.S.C. embodiment shown, the pilot signal Fp is initially obtained via a three-fold frequency demultiplier 14 from a 1À06 Mc. oscillator 12, the output from which is also combined in a frequency adder 11 with that from a colour-burst-synchronized 3À58 Mc. oscillator 10. The resulting 4.64 Mc. signal is combined with the 3À58 Mc. chrominance signal Es in a frequency converter 8 to beat down the frequency of the chrominance signal to 1À06 Mc. prior to synthesis of the recorded composite signal. The reproduction apparatus also includes a 3À58 Mc. oscillator 33, Fig. 2, which combines at 32 with the 1À06 Mc. output from a three-fold frequency multiplier 31 receiving the pilot signal Fp, to produce a 4À64 Mc. signal. This is applied to the frequency converter 30 to restore the chrominance signal frequency band to its original value prior to recombination with the demodulated luminance signal. The invention may also be applied to the PAL system.

Abstract: 1287799 Voice frequency receivers INTER. NATIONAL BUSINESS MACHINES CORP 13 Nov 1969 [16 Dec 1968] 55563/69 Heading H4R [Also in Division G4] In order to increase the response time of a high Q mechanically resonant tuned circuit in a VF receiver of a data transmission system, the input to the circuit is attenuated as soon as the output of the circuit reaches a predetermined threshold. By this means the guard interval required between VF data pulses is reduced since the decay period of the signal in the tuned circuit is considerably reduced relative to the decay period of a signal having unlimited amplitude. As shown, a signal at input 1 is applied via F.E.T. 2 to a piezo electric transducer 5 on one arm of a tuning fork 7. A similar transducer 9 on the fork's other arm is capacitively coupled via an amplifier 13 to a threshold detector 15 whose integrated and amplified output is applied to a flip-flop 23 and also to the gate of F.E.T. 2 so as to cut the latter off. The cessation of output signal on lead 20, 25 causes F.E.T. 2 to reconduct. The restoration of output signal again cuts off F.E.T. 2. This oscillation continues for the duration of the VF signal thus maintaining the amplitude of the signal in the tuned circuit at a desired level. When the VF signal ceases, the flip-flop is restored by the zero signal detector, rectifier-filter 27 and inverter 29. A plurality of such circuits may be connected in parallel for responding to a multifrequency input, e.g. one frequency from each of two sets of frequencies. With the latter arrangement the common input signal is initially subjected to AGC and a common zero signal detector is used for restoring all the flipflops. In an alternative arrangement the output of the flip-flop is used to operate the attenuator. In this case the output of the circuit falls continuously and does not oscillator about a predetermined level. The flip-flop however will still not alter its condition until the input signal ceases and circuit 27, 29 becomes effective.
