摘要:
The invention concerns an element including: 1 sheet (1) including an intermediate zone (29) located between two zones designed to form side walls (9, 11), the intermediate zone (29) being designed to form a flap folded along the tip against one first (9) of the side walls, and elements (51a, 51b) for guiding tears in the sheet (1) the elements forming a single pull tab (58) to cause tears, the pull tab (58) being, in the intermediate zone, spaced apart from the media axis (A) of the zone designed to form the base (3). The invention is, for example, applicable to packaging of melted cheese.

摘要:
In a process for electromagnetic casting of round and hollow ingots, in particular such of aluminum and aluminum alloys, the ingot (7) is rotated about its longitudinal axis (x) during casting. This is achieved by way of a rotatable dummy base (6). With that the metal feed and cooling of the ingot is made symmetrical and, as a result, a more uniform shape is obtained and a more uniform cell structure across the ingot cross-section. In order to promote a stronger stirring effect, a stationary stirrer (8) dipping into the molten part of the ingot (7) can be provided attached to the metal inlet system (3).
摘要:
An assembly including a processed cheese portion (22) and a package (26) closely wrapping the portion. The package includes an element which itself comprises a film (2) tightly wrapping the portion and in contact therewith, and tear-initiating member (11) for enabling the sheet (2) to be torn along at least one tear line (8) when a gripping tab (10) of the element is pulled. At least a first part of the or each tear line (8) is defined by or made from a material of the film (2).
摘要:
A completely openable fluidtight packing wrapper for pasty products and in particular food products such as processed cheese. This wrapper comprises a shell having a bottom (2) of triangular shape bordered by two lateral walls (6, 7) and a wall forming a heel (8). A tearing element (24) comprises two tearing strips (25, 26) each extending in a first portion (27, 32) along one of the lateral edges (22, 23) of the heel (8) and in a direction parallel to this edge and, in a second portion (28, 33) along one of the lateral edges (4, 3) of the bottom (2) and in a direction parallel to this edge, these two strips (25, 26) being at least partly superposed in a third portion (29, 34) in the vicinity of the point (30) of the triangular bottom (2) so as to constitute a single pulling tongue (31) which extends beyond the sheet (1) forming the shell.
摘要:
An electromagnetic mold for vertical continuous casting of rolling slabs, featuring an inductor and an electromagnetic screen partly covering the induction is such that the vertical distance between the lower edge of the inductor and the lower edge of the screen is greater at the narrow sides of the mold than at the broad sides of the mold. As a result of this arrangement it is possible to prevent metal running out of the ingot head at the narrow sides during the start-up phase. The foregoing is achieved at the expense of an insignificant amount of melt circulation occurring in the molten head of the ingot.
摘要:
A device for contactless, vertically downwards continuous casting of metals in an electromagnetic alternating field, has an inductor and an electrically conductive, non-ferromagnetic screen that tapers downwards and features at a vertical distance 9 from this screen an electrically conductive, non-ferromagnetic counter screen that tapers upwards, the distance 9 between the said screen and counter screen being at least 2 mm, at most equal of the height of the inductor and in a continuous process which employs this device the circulation of the melt in the molten head of the ingot is reduced at least in the steady-state phase of casting. The process is particularly suitable for continuous casting aluminum alloys having a magnesium content of at least 2%.
