Title: Machine for printing addresses
IPC: B41L45/00
Filed: 1955-10-19
Abstract: 805,822. Addressing machines. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. Oct. 19, 1955 [Oct. 29, 1954], No. 26972/57. Divided out of 805,821. Class 100(2) A printing machine for printing on a sheet addresses that are carried on individual instrumentalities passed one by one through the machine includes means for checking the addresses as carried by the instrumentalities against on another to determine when there is a change in locality of the addresses, and comprises a first register for receiving data pertaining to an address on one instrumentality and a second register for receiving data pertaining to an address on another instrumentality, and means to compare the respective data thus received in the two registers and to indicate when these are different. The machine may be as described in Specification 805,821 for dealing with three orders of instrumentalities and as shown comprises a lower set of reels 100 (Fig. 1) adapted to feed copy strip MS to be printed past a printing head PH and an upper set of reels 101 adapted to feed a strip of carbon paper CS past the head PH in registry with an advancing address strip. The machine uses the facsimile method of reproduction and is controlled by punched cards bearing addresses to be printed. The comparing registers comprise banks of relays and are arranged so that the data on the first card is stored in the first register and the data on subsequent cards is received in the second register and compared with the data stored in the first register. If the data on the second card corresponds with that on the firts card the second register is cleared ready for reception of the data on the third card. When, however, the data disagree the second rgister is not cleared but retains the data on the subsequent card for comparison with the data on further subsequent cards which is received in the first register the latter having been cleared of the original data pertaining to the first. A further disagreement of data again reverses the registers. When the data disagree a solenoid 1033 (Fig. 3) is actuated to eject a pin from a pin wheel device 1000 on a shaft driven cyclically in connection with advancement through the machine of the cards. The pins are held in ejected or retracted position by spring loaded detents. A disc 1035 is arranged on the same shaft as the device 1000 and pivoted thereon is a segmental arm 1039 adapted to be actuated by an ejected pin on the pin wheel device. The pin pivots the arm 1039 about its pivot 1036 against the action of a spring 1042 thus actuating a bell-crank lever 1048. The lever 1048 operates a link 1050 which actuates a pad PD (Fig. 1) for marking the copy strip MS with ink at the place corresponding to the detected change in locality of the addresses. Ejected pins are reset by a plate having an inclined edge arranged at the back of the disc 1035 in a position to contact and reposition the ejected pins. Specifications 690,161, 690,162, 693,576 and 693,577 [all in Group XL(b)] also are referred to.

Title: Machine for forming a continuous column of articles
IPC: A21C15/00
Filed: 1975-06-26
Abstract: 1480543 Endless conveyers BARILLA G & R F LLI SpA 26 June 1975 [27 June 1974] 27155/75 Heading B8A Rusks 3 fed in rows on a conveyer belt (2) (Fig. 1, not shown) from an oven (not shown), pass on to a conveyer (5), the support surface of which is spread apart in the direction of conveyance. This leads to a further conveyer 15 with which guides 14 are associated for each row of the rusks 3. Transverse pins 13 (Fig. 2, not shown) are disposed at a distance equal to the thickness of a rusk above each lane at the downstream end of the conveyer 15. Each guide 14 leads into a respective shoot 16. Each of the latter feed to a respective lane of a conveyer belt 17 to which the rusks 3 are delivered each standing on end. At the downstream end of the conveyer 4, is provided a series of pivotable shoes 24, each momentarily engaging the top of a respective rusk 3. The next row downstream is also periodically arrested by a series of fingers 33. The latter and the shoes 24 are operable by the action of a single piston cylinder unit 30 to halt two respective rows of the rusks 3 as they pass over a plate 23 which overlies the end of the conveyer 17. As an alternative, two separate units 30 may be used for the shoes 24 and fingers 33. Guides 18 which separate each lane of the rusks on the conveyer 17, terminate in bristles or resilient reeds 34. The plate 23 is succeeded by a plate 35 (Fig. 5) along which each successive row of rusks is conveyed by pushers 38 carried by conveyer chains 37. A cam rail 42 projects and retracts the pushers where necessary. The continuous row of rusks thus produced is conveyed onwards between conveyer members 46 carrying bristles 47 and mounted on conveyer chains 44 of a conveyer 144. 1st Modification.-The arrangement of shoes 24 and fingers 33 are replaced by a series of fingers 103 (Fig. 8) which engage and stop one row of rusks in the shoots 16. The next lower row is stopped by inwardly movable members 109, 110. The latter are operated by the action of cam 107 (shown in Fig. 8 as displacing the members 109, 110, to an open position) which also controls by engaging a member 106, the stops 103 (in Fig. 8 just moving into the blocking position). When the members 109, 110, move outwardly, the row of rusks 3 released thereby drop on to a wheeled carriage 111 which is pushed by a camoperated pusher 116 (Fig. 6) into a position in which the rusks 3 lie between the bristles 47 of the conveyer 144. 2nd Modification (Fig. 12).- A retractable (by means of a ram 36) partitioned casing 134, and interdigitated platforms 140, alternately retractable relative to the casing 134 (by means of a ram 135), enable the columns of rusks 3 to be fed directly from the bases of the shoots 16 to the bristles 47 of the conveyer 144.

Filed: 1976-07-05
Abstract: 1525837 Flaw detection CROWN CORK & SEAL CO Inc 5 July 1976 [25 July 1975] 27934/76 Headings G1A and G1N Apparatus, for inspecting metal containers having a cylindrical sidewall and an end-wall, closed endchute 12 feeding the containers serially into respective pockets of a rotating turret 14 which indexes each container along an arcuate path and discharges it into a conveyer shoot 16. Each container is rotated about its axis by a driver 20, rotation being facilitated by rollers 18 in each pocket. At a first inspection station adjacent the arcuate path a magnetic field from a permanent magnet 62, or from an electromagnet, traverses the flange of the container and an induction coil 64. Passage of a crack or split 70 in the flange causes an untoward variation or fluctuation of the magnetic field leading to a signal from the induction coil which produces a corresponding signal from the detector 24. A proximity detecting transducer 26 utilizing capacitance or eddy currents detects dents in an adjacent container and produces signals to a level detector 28. The preferred embodiment uses a pair of eddy current transducers spaced axially along the sidewall of the container. Photo-electric inspection, Fig. 3. An incandescent bulb 34 provides diffuse white light which passes along a path oriented at about 20 degrees to the sidewall of the container 38 as it passes along the arcuate path defined by the rotating turret. A cadmium sulphide cell 36 is disposed adjacent the source to receive light reflected from the closed end wall of the container. The intensity of the reflected light indicates whether or not the internal surfaces of the container have been lacquer coated. Infrared radiation may be used instead. Discharge of faulty containers, Fig. 4. Valve 31 is actuated to blow faulty containers out of the conveyer shoot in response to signals from the three inspection stations. The split flange detector 22, 24 and the eccentricity or dent detector 26, 28 are coupled to an AND gate 46 which also receives pulses from a proximity detector 25. This senses rotation of a shaft 19, coupled to the turret, by means of a rod 23. The shift register 48 counts output pulses from the AND gate and having received the number representing indexing of the container from an inspection station at which a fault has been sensed to the discharge station actuates the valve 31 to discharge the faulty container. The valve also receives error signals from the photo-electric sensing assembly.
