Title: Improvements relating to Metal Containers having an End with a Tear-out Section
IPC: B21D51/38
Filed: 1967-09-20
Abstract: 1,164,179. Making tearing lines for opening cans. ALUMINUM CO. OF AMERICA. 20 Sept., 1967 [5 Oct., 1966], No. 42796/67. Heading B3J. [Also in Division B8] A metal end 10 for a can &c. has a tear-out strip defined by a multiple score-line comprising a main, deep score line and at least one adjacent parallel shallow score line, the score lines being formed by ridges 29 . . . 31 on a die 26 lowered towards an anvil 27 supporting the can end. The main ridge 29 on the die 26, of truncated V- shape, engages the can end 10 first, causing sideways extrusion (a, b), Fig. 6 (not shown), of metal as the score line is formed. The shallow adjacent ridges 30, 31 then engage the can end 10, and cause sideways extrusion (c, d) of the metal: this secondary extrusion opposes the initial extrusion (a, b). Excessive weakening of the metal, formation of pin holes &c. is thus prevented. Short shallow score lines 35, Fig. 1, are formed as described at junctions Y of main score lines 19, where extrusion flow would otherwise be substantial. In one embodiment, the metal can end 10, having score lines 19, 20 made in this way, has a tear-out strip 13 which at one end terminates in a reduced-width starter section 14 riveted at 15 to an opening tab 16. The opening tab may be flexible, or as shown may be a rigid lever with reinforcing ribs 23. The inner score line 20 terminates at 40, so that the whole of the end of the can may be pulled out. In a modification, a continuous multiple score line (23), Fig. 3 (not shown), extends around the greater part of the periphery of a can end, except where it forms a tongue (25) which may be pulled up by an opening tab. The rim 12 of the can end is seamed in a conventional manner (not further described) to the can walls.

Title: Apparatus for screwing caps on tubes, shells or the like for  example toothpaste or cream tubes etc
IPC: B65B7/14
Filed: 1972-09-15
Abstract: 1390260 Applying screw-caps to containers K G HINTERKOPF 15 Sept 1972 [24 Dec 1971] 42816/72 Heading B8T Screw-caps 3 from a preferably vertical feed conduit 1 are gripped in turn by pincer-like grippers 5 pivoted at 13, 14, which advance them to a respective neck of a tube 7 carried on a mandrel 7a of a turntable head rotating intermittently about a preferably horizontal axis 9. After placing the cap 3 on the tube neck the grippers 5 open by means of an actuating linkage (not shown), and the turntable is indexed (as shown in direction of arrow 10). The cap may be given an initial twist when applied and subsequently screwed on by rotating the tube (26) in a mechanism, Fig. 3 (not shown), in which a plug (25) holds the cap against rotation. When the cap is screwed home, a spring loaded piston (29) is caused to slip at a friction surface (30) with a holder (27) fast with the plug (25) thereby preventing over-tightening.

Title: Ink drop printer
IPC: B41J3/30
Filed: 1973-09-12
Abstract: 1401728 Printers INTERNATIONAL BUSINESS MACHINES CORP 12 Sept 1973 [13 Oct 1972 22 Jan 1973] 42855/73 Heading G4H In an ink drop printer, deflection means for the ink drops is controlled so that each succeeding drop used in printing a continuous line is caused to print at a position separated from that of the last preceding drop used for that line. This reduces the effect of one drop on the next and so improves print quality. Prior to passing between fixed-voltage deflection plates, the drops are charged by voltages from a D/A converter fed from a counter driven at low or high speed according to whether the corresponding area of a character matrix is to be inked or not (so that non-inked areas are skipped through quickly), the D/A converter being gated off (to produce zero output) in the case of non-inked areas. The counter provides the feature whereby succeeding drops do not relate to adjacent positions in a continuous printed line. A capacitive staircase generator may replace the counter and D/A converter.

Title: Improvements in and relating to rubber dummies, teething rings, toys or articles forinfants
Filed: 1965-10-11
Abstract: An infant's article such as a dummy, teething ring, doll, or toy is made of a rubber latex material into which is absorbed an exemplified flavouring material.  The article may be formed from a pre-vulcanized latex by known dipping, heat sensitization, or casting procedures, the article then being soaked in a solution of a flavouring material and dried.  Alternatively, an unvulcanized latex is used to form the article which is then vulcanized and soaked in the flavouring solution.  Either of these methods may be modified by adding the flavouring to the latex before the forming operation.  The articles produced by these methods may be soaked in a chlorine solution to remove any tackiness and may be coloured to correspond to the particular flavouring.

Title: Improvements in winding yarn on bobbins
IPC: B65H69/00
Filed: 1960-12-15
Abstract: 973, 277. Winding yarns; drag arrangements; belt drives. DEERING MILLIKEN RESEARCH CORPORATION. Dec. 15, 1960 [Dec. 16, 1959], No. 43223/60. Headings D1D and D1J. A yarn winding arrangement comprises a turntable 11, Fig. 2, rotatable about an axis 25, a plurality of winding positions spaced apart on the turntable, each winding position comprising a takeup spindle 13 and a supply spindle 15 each rotatable about an individual axis on the turntable, and a common drive 39 for rotating the takeup spindles 13 and the turntable 11. The supply spindles 15 are fitted with nearly empty bobbins 44, the yarn from which is to be added to the yarn already on bobbins 43 on the takeup spindles 13. The spindles 13, 15 all carry whorls 37, the whorls of the spindles 15 being individually braked by tensioned belts 51 and the whorls of the spindles 13 being rotated by a common belt 39. The tension in the belts 51 is adjusted by screws 55. The drive belt 39 passes over a drive pulley 65, Fig. 1, and hence is spaced away from the whorl of one takeup spindle 13, namely the spindle 13a. An operator at a station 111 can remove an empty supply bobbin from the associated supply spindle 15 and replace it by a nearly empty bobbin 44 taken from a supply channel 151, the yarn ends from the new supply bobbin and the takeup bobbin on the spindle 13a being drawn out by hand and placed together under a sewing machine 125 that is used to sew the yarn ends together. The resultant slack is taken up by grasping a handle 145 and swinging an arm 139 clockwise about a support 141 so as to bring a motor driven friction wheel 133, on the arm, against the periphery of the upper flange of the supply bobbin on the spindle 15. When the arm 139 is in this position a lug 147 on the arm 139 closes a microswitch 149 to energize the motor 137 driving the wheel 133. The turntable 11 is held against rotation by a brake shoe 79, Fig. 3, carrying an indexing pin 99 co-operating with holes 107 in the turntable. When the operator actuates a switch 109, Fig. 1, a solenoid 91, Fig. 3, causes the brake 79 and the pin 99 to be temporarily displaced from the turntable whereupon the turntable rotates by a further increment until the pin 99 engages in the next succeeding hole and the solenoid 91 is automatically deenergized. Specification 973,276 is referred to.

Title: Recognition System Using Spatial Filters
IPC: G06V10/88
Filed: 1966-09-29
Abstract: 1,151,190. Pattern recognition using holography. GENERAL ELECTRIC CO. 29 Sept., 1966 [1 Oct., 1965], No. 43655/66. Heading G4R. [Also in Division G2] A pattern recognition system uses a holographic spatial filter. A holographic spatial filter 16 is made (Fig. 1, not shown) by interfering on a photographic medium, the image of a point source of coherent monochromatic light and the image of a plate, showing characters, words or other patterns to be recognized, the plate being illuminated by the same point source. In Fig. 6, collimated light from a coherent monochromatic source 11 illuminates a microfilm 17 of bank cheques, the image of one character passing through an apertured stop 19 to be imaged on to the holographic filter 16. A spot of light from the filter 16 falls on one of an array of photo-cells 23, which one depending on which part of the filter 16 bears the holographic transform of the character identical with the unknown character en the cheque. Stepping motors 41, 46 allow the cheque to be displaced laterally for recognition of successive characters in a line and for the successive cheques to be advanced to the recognition position. Electric contacts 48, bridged by a conductive patch on the microfilm 17, indicate when a cheque is in position, and contacts 51 indicate when a line has been read. Fig. 5 (not shown) shows a modification in which a whole line of words on microfilm is inspected at a time, to obtain an indication of which words used in constructing the filter are present (irrespective of position in the line). A rotatable disc (26) bearing masking patterns and positioned on the film side of the filter, allows the band-pass characteristics of the filter to be effectively changed by removing selected diffraction orders from the light. This alters the selectivity of the recognition. Counts are kept of the number of lines containing words recognised, in the current microfilm frame and altogether, and of the number of frames which have passed. The number of occurrences of a given word in a particular line could be obtained from the amplitude of the photo-cell output. Apart from bank cheques, application to marking exam papers, evaluating printing quality, and transferring addresses on printing plates to magnetic tape are described. A helium-neon gas laser is preferred as the light source but a filtered mercury vapour gas discharge lamp or a small filtered tungsten lamp may be used instead. To eliminate undesirable diffraction due to dust and scratches in the laser optics, the system may obtain its laser light via a small aperture. A television camera may replace the photocells. To reduce the effect of scratches on and non- uniform thickness in the microfilm, it may be immersed in a fluid having a suitable refractive index. It is mentioned that when a pattern is recognised, an image of it rather than a spot of light may be produced.
