Title: Improvements relating to bottle capsules
Inventor: BRUUN OTTO JOHANNES
IPC: B65D41/14
Filed: 1965-12-31
Abstract: Blanks of pliable sheet material, such as aluminium foil, for forming pleated bottle capsules, are coated on both sides with adhesive to stick together to surfaces brought together by the pleating, and to enable the capsule to be stuck to a bottle neck on which it is applied.  The adhesive used for the latter purpose is water-sensitive.  The adhesive for securing the pleats may be heat-sensitive, in which case the capsule is heated after applica) tion of the adhesive to a blank and subsequent folding of the capsule therefrom.  Application of the heat-sensitive and water-sensitive adhesives to the surface of the blank forming the inside of the capsule may be by two rollers having complementary patterns to deposit the adhesives side by side, or alternatively the heat-sensitive adhesive may be applied by rolling to the whole inner surface, and the water-sensitive adhesive mubsequently applied to selected regions by rolling, on top of the heat-sensitive layer.  In a further modification the inner surface is roller-coated with a layer of emulsion consisting of a thermoplastic adhesive emulsified with an aqueous adhesive.  On drying the coating becomes a mosaic of small particles of thermoplastic and water-sensitive adhesives.  An alternative method of producing the capsules comprises coating a web with heat- and water-sensitive adhesives e.g. shellac based adhesive and polyvinyl acetate respectively, on respective sides, moistening the latter side prior to capsule formation, and shaping the capsule in the wet state.  On subsequent heating the heat-sensitive adhesive on the outer surface is activated, securing the foils together, and the water-sensitive adhesive is dried, sticking the pleats together and providing an adhesive inner surface.  If heat-sensitive adhesives are used both inside and outside the capsule, different adhesives may be used on the two surfaces, to minimise adherence together on nesting of a number of such capsules.

Title: A pulse distributor for time division multiplexing systems
IPC: H04J3/04
Filed: 1967-12-11
Abstract: 1,204,150. Distributers. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. 11 Dec., 1967 [9 Dec., 1966], No. 56174/67. Heading H4P. A distributer comprises a matrix of n (e.g. 6) rows and m (e.g. 8) columns of gates A 11 -A 68  a variable number of which are scanned in each distributer cycle. Store B indicates which of the gates (e.g. A 11 , A 12 , A 22 ) are to be scanned and provides selection signals to the appropriate row and column control units E 11 -E 16  and E 21 - E 28 . At the beginning of each cycle all the control units are reset by a pulse Ps. A subsequent start pulse Avv primes the row control units E 11 -E 16 , and the lowest-numbered one of these that is also receiving a signal from B (i.e. unit E 11  associated with the first gate A 11  to be scanned) is enabled and passes a signal to all the associated row gates A 11 -A 18  and to all the column control units E 21 -E 28 . The lowestnumbered of the required column control units E 21  is enabled and, when a clock pulse Sc occurs, passes a pulse to all the associated column gates. When now a first clock pulse C is received only one of the gates (i.e. A 11 ) will have all three inputs energized and that gate will pass the first clock pulse to its output. An immediately following clock pulse Re resets the enabled column unit. As further gates in the first selected row are to be scanned the next appropriate column control unit E 22  is enabled by virtue of the resetting of the previous one and the next pulse Sc, so selecting a second gate A12 which pulses when the second pulse C arrives. If no further gates in the selected row are to be scanned gates Ac, Ar are enabled by gate Oc. A clock pulse Rr now passes via gate Ar to reset the enabled row control unit E 11 , this resetting enabling the next required row control unit E 12 . A clock pulse Sc now passes via gate Ac to enable the required column control unit E 22  and the third clock pulse C appears at the output of the selected gate A 22 . The required gates are selected successively, and repeatedly unless a change occurs in B. Details of the row and column control units are given, Figs. 3 and 4 (not shown).
