Abstract: 1,228,952. Attaching articles to cards; feeding webs; feeding articles. INTERNATIONAL INPAK Inc. 14 March, 1968 [15 March, 1967 (2)], No. 12351/68. Headings B8C, B8R and B8S. An apparatus for attaching articles to cards comprises means to pass a heat shrinkable film web through successive apertures in a card to form loops of film extending from one side of the card, means to adhere the film to the card and means to insert the articles into the loops. The cards may be cut between the apertures to form individual article packages. A film web 23 (Figs. 1, 18) is engaged and held taut by counterclockwise rotating rollers 22 and a pressure roller 21 which rests on the rollers 22 when the film is pulled downwardly and forced through the card apertures 4 by two fingers 40, 41. Hooks 24 on a spring loaded arm 25 lift the roller 21 when the fingers disengage the film. As the finger 41 enters the aperture, adjustable supports 88, 89 rise to engage the card web between the apertures to allow a heated pad 108 to seal the film to heat activatable adhesive between the apertures. As the finger 40 and the supports 88, 89 descend (see Fig. 1) the other finger 41 moves the card to the left as shown to allow the finger 40 to enter the next aperture, the supports ascending again and the process being repeated. Adjustable rod 70 allow the fingers to cope with varying aperture distances. The fingers 40, 41 are adjustable to vary loop depth. The card is fed along grooves in rails 218 (Fig. 7) by wheels (224, 225), Fig. 9, to a retractable stop 232 whereupon air is blown from beneath the card to inflate the loops into which cylindrical forms 250 are then inserted. Articles are pushed from an apertured container 264, Fig. 8, contained in a hopper 263 (Fig. 13) along tubes 260 by two rows of rods 271 Figs. 7, 13. The tubes are filled with columns of the articles the foremost of which enter the loops as the forms recede. When the rods are withdrawn the container, originally supported by the lowermost row of articles, drops to allow the next batch of articles to be affected. The card moves on against a feeler (286), Fig. 12, which causes a guide (298) to rise and direct the card against a stop (302). Heated cutters 308, Fig. 18, descend to cut the film along an existing series of cuts in the card between the articles. The card enters a film shrinking unit 324, e.g. using hot air and then passes between rotary cutters 326 which sever the lands 7 from the card to yield individual units.

Abstract: 1,229,288. Slip couplings. GENERAL SIGNAL CORP. 23 July, 1968 [26 July, 1967], No. 35172/68. Headings F2C and F2L. [Also in Division H2] A butterfly valve 11 in a conduit 10 is rotatable, via gears 17-21 and a clutch, by a motor 15. Alternatively the valve may be operated by a hand wheel 70. The clutch remains in engagement due to Belleville washers 45 but becomes disengaged when the torque exceeds the spring pressure holding plates 35, 40, 22 together. The plate 22 is keyed at 31 to a drive shaft 30 but is slidable axially of the shaft. The plate 35, which is fixed to a driven shaft 12, has a plurality of projections 55 each having square and inclined faces 56, 58 for engagement respectively with square and inclined faces 57, 59 in recesses in a plate 40. This plate is free to rotate and to slide vertically. Projections 49 of the tooth plate 22 engage in recesses in the upper side of the plate 40 but the height and depth of these projections and recesses are greater than those of the projection 55 and their corresponding recesses. This is to provide for the actuation of a switch 60 by vertical movement of the plate 40 and for the actuation of a switch 61 by vertical movement of the plate 22. Switch 61 will not be actuated except by the greater axial movement of plate 22. The switches 60, 61, which are in the reversing leads of the motor 15 interrupt drive from the motor when excessive torque occurs in the clutch, causing one or other of the plates 22, 40 to lift. This excess torque arises when the valve 11, at each end of its 90 degree rotation, meets a limit. Thus, at one limit the projections 55 will cam the plates 40, 22 upwardly causing declutching and disconnection of the motor supply through switch 60. At the other limit, projections 49 will cause declutching and cut-off of the motor through switch 61. Should the valve meet an obstruction between the normal limits, declutching &c. will similarly occur. When the shaft 30 is to be operated by the hand wheel 70, a locking-pin 76 is withdrawn from a recess 77 and inserted at 74, 75 to lock the wheel 70 to the shaft 30. Withdrawal of the pin 76 from the recess 77 allows a switch 82 to break the power circuit to the switches 60, 61 and the motor 15.

Abstract: 1,238,707. Typewriters. FACIT-HALDA AB. 4 Nov., 1968 [2 Nov., 1967], No. 52249/68. Heading B6F. A tabulator mechanism for typewriters having power-operated carriages includes provision for prevention of damage thereto in the event of depression of the tabulator stop setting key 21<SP>1</SP> during carriage travel in either direction, or depression of the tabulation key during carriage return. The tabulator stop setting key 21<SP>1</SP> acts through a link 1 to pivot an arm 2 on which a stop setting member 4 is resiliently mounted. A lug 4d on the member 4 is thereby engageable with a tubulator stop 8 mounted on the carriage and acts to displace the stop from its inoperative position, as shown, wherein the curved end 11a of a spring finger 11 engages a recess 8a in the stop 8, to its operative position where the spring finger 11 engages a second recess 8b. While the tabulator stop setting key is depressed, the lug 4d therefore lies between two unactuated stops 8 and carriage travel at that time would cause undesired engagement between such a stop and the lug 4d. The stop setting member is accordingly resiliently mounted by means of a pair of pins (5, 6), Fig. 3 (not shown), and a spring (7), the upper pin (5) engaging a heart-shaped slot (4b) in the member 4, so that a sideways force on the lug 4d causes camming action between the upper pin (5) and the slot (4b), whereby the member 4 is forced downwardly out of operative position. The tabulator key acts to lift one of a plurality of denominational central stops 12 guided by a slotted plate 13. If a stop 12 is lifted during carriage return travel, damage, due to an actuated stop 8 striking the stop 12 in the wrong direction, is prevented through resilient mounting of the plate 13. Displacement of the plate 13 in the carriage return direction, i.e. to the right as shown acts through a spring-biased lever 16 to push downwardly on a link 19, whereby a bail (23, Fig. 4) is pivoted downwardly, the bail engaging a foot (12a) on the stop 12 and thereby acting to depress the stop out of operative position. On return movement of the plate 13, and hence the lever 16, the stop 12 remains in its inoperative position owing to relative sliding movement between the link 19 and the lug 16a of the lever 16.

An optical bulk storage arrangement comprises an information carrier 1, a camera device 11 for the read-out of an objective lens 6, which lens provides an image of the information carrier, means on the camera for temporarily storing the image, means 12 for causing the temporary storage means to be exposed to the image, means 9 for varying the position of the focal plane of the lens 6 relative to the information carrier between two exposures of the camera and means for initiating the exposure of the camera when the focal plane is just passing through the carrier. The store may be for electronic computers and the information carriers strips of film 1 stored in groups of up to 500 on a shelf. A desired strip is rapidly brought into a reading position by four cables driven by drums (Fig. 2, not shown) but this causes vibrations in the strip which make reading difficult. To overcome this the microscope objective lens 6 is vibrated by an electromagnet 9 such that a flash lamp 12 illuminates the camera screen when the lens 6 and the carrier 1 are the correct distance apart for good reading, i.e. the information on the carrier 1 can be displayed sharply on the camera screen 10. Alternatively the carrier l can be vibrated or a movable member can be placed on the ray path. This is effected by an autocollimating device (Fig. 3, not shown) which triggers the flash bulb 12 at the correct moment. The film 1 may be of plastics with dots produced by high resolution photolaquers. It is preferably strongly reflective (Figs. 5 and 6, not shown) and the information may be stored in holes in the reflecting layer made by a photo lithographic etching process or by burning in with a laser beam. Using the laser beam further information can be burnt in. The camera 11 can be a television pick-up tube, vidicon superorthicon tubes or supericononscope tubes. The flash lamp 12 can be flash-light tube, sparks or pulsed lasers. The television pick-up tube is scanned line by line by a beam before and after exposure.
