Title: Diaper with back-to-back transition web facing
IPC: A61F13/15
Filed: 1974-07-08
Abstract: 1473691 Web formers; non-woven fabric with a fibre length gradient JOHNSON & JOHNSON 8 July 1974 [9 July 1973] 30096/74 Headings DIN and D1R [Also in Division A5] A diaper comprises a porous fibrous facing layer including an inner stratum 13 of predominately short fibres overlaid and underlaid by outer strata having a greater proportion of long fibres than the inner stratum, the facing layer being delaminatable along the short fibre stratum. The diaper also has an absorbent pad and a water-imprevious backing sheet. A roll of short fibres 41 feeds a source of short fibres to a grinding mill 42 from which a fibre stream is blown onto a belt 43 as a layer 44 which passes under a compacting roll 46 to emerge as a self sustaining web. The web is further compressed by calender rolls 47 and its upper surface moisturised by means of a nozzle 48 and formed into a skin 51 by calender rolls 49. Densified portions are formed by an embossing roll 52 and the web contacts a web of facing material 16 and the backing sheet 12, lines of adhesive being applied from an applicator 59. The facing layer is formed by air-laying two separate fabrics 30, 30' which are juxtaposed by a combining means 77. Fibres are air-laid on a foraminous belt 90 by a suction box 91, the belt 90 having three single lickerins, the first depositing a long fibre layer, the second a short fibre layer downstream and the third a long fibre layer yet further downstream, the face of the layer adjacent belt 90 being long fibre enriched and the other short fibre enriched. Using a conveyer 78 the combined web is passed to a bonding station where an aqueous dispersion of acrylonitrile binding agent and a surfactant are supplied from a source 79, and to a drying station 81 where it is dried at 82 and the exterior surface heated at 83 and 84. After complete drying the web enters the diaper production stream at the position of roller 85 which brings it into contact with the absorbent web of the diaper. The short fibres are preferably wood or cotton. The long fibres in one fabric may be rayon and in the other polyester or polyvinyl alcohol.

Patent GB-641549-A (GB)
Title: Improvements in or relating to the production of striped flexible strip material
IPC: B05D5/06
Filed: 1946-10-11
Abstract: A stripe is applied to flexible thermoplastic tubing by advancing the tubing adjacent to a nozzle which deposits a striping liquid in a continuous band on the tubing, drying the deposited liquid, and heating to fuse the dried deposit.  The tubing which may be of cellulose ester, a vinyl resin such as vinyl chloride polymerized alone or with a minor proportion of vinyl acetate, vinylidene chloride or an acrylic ester, is plasticized for flexibility.  The striping liquid may contain the same resin as the base material and the same amount of plasticizer.  The tubing may be freshly extruded from a heated die, the residual heat in the tube being used to evaporate the solvent.  The fusion of the stripe may be effected by applying a small flame.  The striping liquid may comprise polyvinyl chloride in methyl ethyl ketone with a plasticizer and colouring matter. Alternatively, a dispersion of polyvinyl chloride in tricresyl phosphate, containing a non-solvent thinner such as hexane, may be used, or an emulsion polymer of vinyl chloride and vinylidene chloride containing a plasticizer and colouring matter.  A sinuous stripe may be formed by oscillating the nozzle.

Abstract: 355,571. Combination locks. BADISCHE SCHLOSSFABRIKATION GES., 112, Sofienstrasse, Kartsruhe, Germany. Oct. 14, 1930, No. 30668. Convention date, Oct. 14, 1929. [Class 44.] In a lock having a spring-shot latch bolt withdrawable by a sliding knob, and having locking discs set to release position by rotation of the knob, the discs are set to locking position, when the bolt is shot, by sliding the knob in a direction the opposite to that for withdrawing the bolt. The knob 17 guided in the cover-plate 16 has a stem 19 the inner end of which engages in a slot 5 in a sliding plate 2 which carries the bolt 3 and an upstanding projection 4. A plate 23 slidable by the knob, has a depending projection 24, and a disc 20 rotated by the knob has a radial arm 21. A spring 27 having one limb bearing against bolt 3, and the other limb bearing against projection 24, its end normally resting against a stop 26, normally holds the bolt in a slot position and the knob spindle 19 against the right-hand end of slot 5. Two locking discs 7 and a smaller intermediate disc 8 have large central apertures within which engage four pins 15 secured to the casing 1, the apertures allowing the requisite sliding movement of the spindle 19. The discs 7 are rotatable about the pins, the disc 8 being held against rotation by engagement of the pins in recesses. Each locking disc has a radial slot 12 opening at the periphery, and release sliding movement of the bolt is possible only when these slots register in line with projection 4 as shown, Fig. 2. Two of the pins extend upwards to form pivots for a pair of hook-shaped levers the short arms of which overlap in the path of spindle 19. The longer arms 9 extend outwards as shown. Each locking disc has a projection 14 extending upwards into the paths of arms 9, 21. The discs are successively brought to the release position by rotation of the knob, first in one direction, then the other, the arm 21 engaging the projection 14 to set the disc. The correct setting is obtained by suitable markings on the knob &c. The discs are moved to throw slots 12 out of register, with one another and with projection 4, so locking the bolt in slot position, by sliding knob 17 and spindle 19 to the left-hand end of slot 5, the spindle engaging the short arms of the levers and rocking them so that their ends 9 engage projections 14 and rotate the discs. Prior to so sliding spindle 19, the knob is rotated to bring arm 21 into line with projection 24, so that subsequent rotation of the discs is not obstructed.
