In an infusion bag made of permeable paper or the like, and generally of flat form wherein one margin is folded and the others seamed, at least one pleat is formed in at least one of the side walls and extends transversely with respect to, and terminates at, the folded margin, so that the volume of the bag is increased during infusion. In a preferred construction, two flattened folds 2, 3 are formed longitudinally in a blank on web of blanks of paper which has been made heat sealable on one side by a layer of a thermoplastic synthetic material, the blank being made into either a flat bag or one as in Fig. 1 with a bottom fold 4 formed during heat sealing of the lateral margins 5, 6 After insertion of the contents, the bag 1 is either heat sealed as at 7, Fig. 1, or closed by a staple or stitching, a tag being secured thereto, Fig. 5. In an alternative embodiment, the folds 2, 3 are formed to face in the opposite direction. The paper need not be coated, but e.g. a thermoplastic glue may be used instead to join the seams.

IPC: D06B3/02
Filed: 1964-08-19
Abstract: Apparatus for the continuous treatment of textile material with fluid comprises a vessel (1) rotated about its axis of symmetry (X-X), a tube (6) extending into the vessel along the said axis and terminating short of the closed end (3) of the vessel means e.g. a pair of rollers (19), feeding the material into the annular space (18) between the wall of vessel and the tube, and means e.g. a pair of drawing rollers (20), withdrawing the material through the tube away from the closed end, and means e.g. a pipe (15), for feeding treating fluid into the vessel through the tube (6), the Figure (not shown).  The vessel may have a right circular cylindrical wall or a frustoconical wall.  The tube (6) extends through a fixed cover (5) for the vessel, which cover is also provided with a material inlet port (11) and a port (12) leading to an air extractor.  Inside the vessel, close to but spaced apart from the end of the tube there is a frustoconical grid (8) supporting the material.  In the case of treatment with a liquid, the vessel is preferably situated with its axis of symmetry inclined to the vertical so that spent liquid spills over the lowermost point of the rim of the vessel to be wholly or partly recirculated or passed to waste.  In use of the apparatus, material preferably in the form of a tow is coiled or plaited into the vessel, the fluid passing down the tube, countercurrent to the material, and up through the annular space (18) also countercurrent to the material.  Several successive treatments of the material can be effected in a series of apparatus as described, such treatments comprising washing, bleaching and drying.

Abstract: 1,115,367. Ring counters; electric selective signalling. RADIO CORPORATION OF AMERICA. 11 Aug., 1965 [31 Aug., 1964], No. 34351/65. Headings G4A and G4H. Logic circuitry including n pairs of gates (n > 2) comprises means for applying to each first gate a different one of n signals, one of said signals having a value such as to prime the gate to which it is applied, the other n-1 signals being such as to disable the remaining n - 1 first gates and means for applying a timing signal to all the first gates so that one first gate is enabled, the logical sum of the output of the enabled gate with the output of its associated second gate being applied to disable all the remaining second gates. In the embodiment of Fig. 4, if only A = 0, only NOR gate 20a is primed and when a timing pulse TP = 0 is applied, a " 1 " output on lead A 1  is obtained which disables NOR gates 22b, 24b, the outputs from the second and third pairs of gates enabling NOR gate 20b. In the embodiment of Fig. 5, a " 1 " input applied to the first AND gate 30a together with " 0 " inputs to AND gates 31a, 32a results in a " 1 " output from OR gate 33 when a timing pulse is applied, this output, after inversion disabling gates 31b, 32b. The embodiment of Fig. 6 operates as a ring counter so that, if initially A = 1, B=C=D=E=F=0, the first timing pulse enables NOR gate 42 and when it terminates NOR gate 62 is enabled so that outputs A=C=D=E=F=0 and B=1 are obtained. The embodiment of Fig. 7 (not shown) also operates as a ring counter, the output from an enabled NOR gate being inverted and after a delay priming the first NOR gate of the next pair.

Abstract: 1,161,605. Cartons. PNEUMATIC SCALE CORP. 1 Aug., 1966, No. 34360/66. Heading B8P. The lid of a flip-top carton is formed from integral panels 52, 54, 56, and panel 48 of the carton blank. The integral panels are connected by a weakened score line 58 to the side wall panels 12, 14, and a front wall panel 16. Prior to erection of the carton, the integral panels are folded along score lines 58, 82, and the upper faces of sections 86, 88 of the panels are adhered together to form a band of double thickness running along the underside of panels 12, 14, 16. The blank is folded into tubular form along the fold lines 20, 22, 24, 26 and flap 28 is adhered to the side wall 12 by an adhesive strip (104) (Fig. 4, not shown). The bottom end closure for the carton is effected by inwardly folding and adhering flaps 30, and 32 to flap 38 which is then adhered to flap 40 to complete the closure (Figs. 4-8, not shown). After the carton has been filled, it is sealed by adhering the hinged flap 48 to the inwardly folded tabs 90, 92, 94 which project from the double thickness band that runs along the outside of the upper edge of three sides of the carton (Figs. 8-10, not shown). The carton is opened by pulling the lid upwardly to break the weakened line 58 leaving the lid hinged along line 50. Offset score lines 57, 59 and cut-out portions 96, 98 alleviate the stress in the band when folded about the corners. Cut out portions 100 aid in sealing the lid, and portions 120 facilitate reclosure of the lid. The line 58 may be weakened by elongated slits or perferations. A hot melt adhesive may be used and the carton may be sealed at the upper end and filled through the bottom which is then sealed. It may include a liner bag.
