Title: Improvements in or relating to packet take-off apparatus for packing machines
IPC: B65B19/32
Filed: 1966-10-12
Abstract: 1,220,671. Package handling apparatus. MOLINS MACHINE CO. Ltd. and L. THORNTON. 11 Oct., 1967 [12 Oct., 1966], No. 45548/66. Heading B8C. Apparatus for delivering filled packets from a packaging machine includes a plurality of handling mechanisms arranged for rotary movement, each mechanism comprising means for receiving a packet, means for rejecting faulty packets in response to a signal from the machine, and means for releasing good packets at an output station. The apparatus is particularly suitable for use in conjunction with the packaging machine disclosed in Specification 1,171,762. Cigarette packets 607, moving along a guide rail 622 on a packaging machine, encounter a fixed plough 623 and are simultaneously embraced by a pair of jaws 605 which are pivoted at 606 on a rotating table 601 and controlled by a fixed cam 615 and followers 614. A pressure plate 624 pushes the packets down between the jaws 605 and against an ejector plate 616 on a shaft 617. On the other end of shaft 617, there is a keeper 620 which is pushed into engageemnt with an electromagnet 621 and is held by the magnet, providing the packet is a good one, so that the packet can continue past scoop 602. However, if detectors in the packaging machine have previously indicated that the package is faulty, then magnet 621 is not energized and a spring 619 pushes the package to the ends of jaws 605 so that it can be removed by scoop 602. Good packages continue to be rotated by jaws 605 until they reach a further guide 625, by which point the jaws are open and the packages are engaged by pushers 629 on a decelerator unit 603. The pushers 629 are mounted on arms 627 which are pivoted at 628 on a rotating disc 626. The arms 627 are caused by springs 630 to engage a fixed eccentric shaft 631 so that the pushers 629 decelerate whilst in contact with packages 607 and accelerate during the remainder of their travel. Finally, the packages reach a paddle wheel 632 which pushes them on to a conveyer 604. In a modification, Fig. 2 (not shown), the arms of the decelerator unit terminate in open-fronted pockets for conveying the packages and also have slots which receive the fixed eccentric shaft. Further, the paddle wheel 632 may be replaced by a suctionoperated device.

Abstract: 1,161,236. Sound analysis; frequency changing circuits. CURTISS-WRIGHT CORP. 31 Aug., 1966 [6 Dec., 1965], No. 45675/68. Divided out of 1,161,235. Headings H3T and H4D. A frequency ratio generator, e.g. for use with the sound analyser of the parent Specification (see Division H4), produces an electrical signal of frequency that continuously bears a predetermined numerical ratio to a slowly varying frequency of a pure tone signal. The frequency ratio generator 34 shown in Fig. 2 comprises a 100 kHz. local oscillator 152 whose third harmonic is mixed at 150 with the pure tone signal of frequency f L . The resulting 300 kHz. signal and its upper and lower sidebands are selectively mixed with outputs of a chain of cascaded mixers and binary frequency dividers 1 to 13 supplied at 152a with a 100 kHz. signal. Each mixer (except the first) receives as one input half the frequency of the output of the preceding mixer, and as a second input either the 300 kHz. signal or one of said side-bands, and provides at its output the frequency difference of the two inputs. The output of the final mixer has a frequency of 200 kHz. + a 0 f L + a 1 f L /2 + a 2 f L /4 + . . ., where a is zero or unity, i.e. a frequency 200 kHz + Kf L , where k is expressed as a binary fraction between 0 and 2. To extend the ratio K effectively beyond the range 0 to 2, frequency multipliers may be used to step up the frequency of the input signal of the frequency ratio generator. In each mixer and binary divider circuit (Fig. 5) the two input signals are applied via transformer T 1  and buffer amplifier 164 to dual transistor VIIa, VIIb for mixing and amplification. The resulting difference frequency output from tuned transformer T 2  is amplified at V 13 , V 14 , shaped by a Schmitt trigger V 15 , V 16  and frequency-halved by a bi-stable circuit V 18 , V 19 .

Abstract: 985,541. Endless conveyers. ANCIENS ETABLISSEMENTS A. SAVY JEANJEAN & CIE. Dec. 5, 1962 [Dec. 8, 1961], No. 45907/62. Heading B8A. A device for transferring articles comprises a continuously driven longitudinal feed conveyer belt T 1  provided at its downstream end with a retractable depositing nose 5, a longitudinal receiving conveyer belt T 2  adjacent the nose 5, a transverse receiving conveyer belt T 3  located under the nose 5 and uncovered when the nose 5 is retracted, a photo-electric cell and light source on opposite sides of, and just above the feed belt T 1  to control two electromagnetic clutch and brake units which control the movement of the nose 5 and the movement of the transverse belt T 3  respectively. Normally, the nose clutch and brake unit is deenergized and the nose is in its fully projecting position, and the transverse belt clutch and brake unit is energized to drive the belt T 3 . The depositing nose 5 is formed by the endless belt T 1  passing around two rollers 6, 7 which are carried on a rigid frame 8, movable on rollers 9 along runways 10. The carriage 8 is retracted against a spring 21 by means of a cam 33 on a driven shaft 17a operating a lever system comprising an arm 31 fixed to a lever 26 pivoted at 27, a link 25, a lever 23 pivoted at 24 and a link 22. One end of the link 25 is adjustable in an arcuate slot 28 in the lever 26, by means of a wheel 29. The belt T 1  is driven by an electric motor 12 through a reduction gear 13, sprocket wheels 14, 15, 18, 19, and chains 16, 20. One electro-magnetic clutch when energized transmits drive from the shaft incorporating the sprocket wheels 15, 18 to the driven shaft 17a, thus retracting the nose 5, causing articles to fall from the belt T 1  on to the transverse belt T 3  which is halted due to a simultaneous de-energization of the second electromagnetic clutch. The number of articles passing along the belt T 1  register through the photo-electric device, with a memory unit which after a pre-determined number, sends an electrical impulse to a control unit. The latter, through a series of relays and switches energizes the nose retracting clutch unit and deenergizes the transverse belt drive clutch. Upon reaching the fully retracted nose position, cams on the driven shaft 17a operate electrical switches which return the circuit to its original condition.

[Also in Division G2] In a system for checking the entry of data from a keyboard, the operator enters the data as two different sequences of data, one of the sequences then being re-arranged automatically for comparison with the other sequence. Information, e.g. an amount, entered on a cheque, is optically projected on a display in a scrambled order by an arrangement of optical fibres 101, the operator keys in the scrambled sequence, e.g. into a store 108, electrical connections 105 unscramble the character sequence to the original order 100 for storage at 110 and comparison with a subsequent straight entry from a different set of optical fibres 103. A check digit may be calculated from the unscrambled first entry for checking with the second entry, and this check may only be initiated when the contents of stores 109, 110 are identical. In another embodiment, the first entry is straight and the second entry is scrambled. A more detailed system is described in which each digit of the first sequence is converted to binary code, serialized and entered in a store at a location corresponding to that of the original sequence under control of a counter advanced by successive entry of characters and an address unscrambling circuit. Each stored character read out by the counter and a straight addressing circuit is compared with a character in the second sequence, advancement of the counter again being effected in response to successive entry of characters. Preferably, after reading in the first sequence, the counter is reset to a state corresponding to the number of non-significant blanks so that these blanks need not be keyed in for the second sequence.

Abstract: 1279500 Treating tobacco PHILIP MORRIS Inc 25 Sept 1969 [28 Oct 1968] 47367/69 Heading A2C Tobacco plant parts are extracted with water, the extract is treated to remove therefrom 20 to 95% by weight of the metallic ions whose salts in tobacco melt at temperatures from 600 to 850F, and the treated extract is then recombined with the extracted tobacco. The metal ions, especially potassium ions, are removed by treatment of the extract with a cation exchange resin either alone or following treatment with an anion exchange resin, or are removed by electrodialysis. In the examples, powdered bright tobacco stems are extracted and, after recombining with the treated extract, are cooked under pressure, refined, and the refined slurry cast into sheets. Where a strongly acidic cation exchange resin was used alone, the refined slurry was adjusted to pH 5.5 by the addition of ammonia, calcium hydroxide, or a mixture of potassium hydroxide and calcium hydroxide, before casting.
