Abstract:
A porous food product is prepared by mixing sodium alginate and a calcium compound with ground fish or meat, heating the mixture, introducing a pressurized gas and an acid into the mixture, the acid liberating calcium ions from the calcium compound to cause the sodium alginate to form a gel which confers a porous structure on the product, and reducing the pressure to liberate gas and form gas bubbles in the product.
Abstract:
The invention relates to a closing arrangements on cans and similar containers of the type which has at least one plane end wall of sheet metal with a hole punched out in the end wall. The cut surface of the said punched-out hole may be sealed effectively by a closing arrangement which is designed as a tubular plastic body with flanges projecting from the plastic body. The flanges embrace the edge zone of the hole when the closing arrangement is pressed into the hole, at the same time as the said cut edge of the end wall is pressed so as to form a seal against, or "is embedded in," the outside of the tubular plastic body.
Abstract:
A method for the production of books or bound documents from a material web (4) which comprises folding lines (6,7) or perforation lines arranged at a distance from one another and whose one side possesses a thin coating of an adhesive capable of being activated, includes printing the web (4) with the desired text and subsequently folding the web together in a folding pattern. After folding together of the web (4) the adhesive is activated so that layers with adhesive facing one another are joined together to form book-pages which can be bound together in a cover (15).
Abstract:
A material (1) in the form of sheets or a web is provided with a watermarklike pattern (12) in form of a text, figure or similar identification mark visible or displayable in transmitted light by means of relieflike mechanical working off of material, for example grinding, milling etc., corresponding to the desired pattern (12).
Abstract:
The invention relates to a packing container which is intended for liquid contents and is of the type which comprises a container body with at least one straight side wall (1) and an upper end wall (2) which is joined to the side wall (1) along a folding line (5) so as to form a relatively sharp transition between the package side (1) and the end wall (2). The upper end wall (2) is provided with a hole (4) penetrating the package wall which preferably is of triangular shape and which with one of its points reaches up to the lateral edge (5) between the upper end wall (2) of the package and its side wall (1). The hole (4) is covered from the inside by a thin plastic film, and from the hole (4) emanate two diverging perforation lines (6) which extend up to a common crease line (7) arranged in the upper end wall (2). Over the hole (4) and parts of the perforation lines (6) a further cover strip (8) with a thermoplastic coating is provided. The cover strip (8) is sealed to the inner plastic film exposed in the hole (4) and, at least in the region between the crease lines (6), to the upper end wall (2).
Abstract:
A method and apparatus for manufacturing paper sheets having an appearance of being hand-made, the method comprising the steps of forming watermarks on a continuous web along longitudinal and transverse zones spaced according to the width and length of the paper sheets, drying the continuous web, crushing longitudinal and transverse regions of the dried continuous web within the watermarked longitudinal and transverse zones, respectively, tearing and separating the dried continuous web along the longitudinal and transverse crushed regions, respectively.
Abstract:
The invention relates a heat exchanger plate (1) comprising a number of turbulence-promoting protuberances (4) that project from the plane (3) of the heat exchanger plate. The protuberances (4) have a surface profile (6) for promoting break-up of laminar boundary layers. The invention also relates to a plate heat exchanger comprising such heat exchanger plates (1).
Abstract:
A flexible material comprises a sheet or web of deformable heat-sealable plastic material having at least one face a surface relief pattern comprising a multitude of small, closely spaced depressions and/or elevations serving to impart increased rigidity and optionally one or more layers, e.g. of aluminum foil, laminated to said plastic material over said relief pattern.
Abstract:
A pack for liquids is made at least partially from cardboard or the like, which is impervious to liquid at least on its one surface, by virtue of a plastics coating. The pack has side walls (2-3), a bottom and a top wall (1), which are connected together at least partially by fold (9) and/or sealing seams (4), a tear-open pouring opening (6) which is disposed in the top wall (1) adjacent the edge line (9) and which is preferably covered over by a tear-off cover strip (7) and a pouring edge (8) which is disposed in one plane with the top wall (1). A separate plastics strip (10) is sealed in position in the region of the pouring opening (6), covering over same, and extends beyond the edge line (9) of the top wall (1) with an unsealed end (11), forming a pouring edge (8), and the surface of the plastics strip (10), which covers over the pouring opening (6), is stamped out, exposing the opening (6), and is laid over around the edge (12) of the opening and is sealed in position from the underside.
Abstract:
A fluid pack made of plastics-coated paper in which the side walls (2) and/or the cover (1) are connected together by way of fold edges (9) and provided in the cover (1) is an opening device (7) having a cover strip (10) which sealingly engages over a stamped-out hole (6).So that the opening device (7) can be produced in an operationally reliable and economic fashion even in a high-capacity machine, the cover strip (10) is injected plastics material and the edge regions (13) thereof cover over the edge portions (14) of the stamped-out hole (6) on both inner and outer sides of the hole.
