Abstract: A device for removing a band (2) wrapped around a bundle (1) of sheets by means of a cutting device (11). The cutter (7) of the cutting device is arranged on the plane on which the bundle is transported in such a way that it dips into a side face of the bundle, cutting along the entire length of the bundle and thereby severing the band located at right angles to the side face. The severed band (2) is grasped on the side opposite the cutting by a hook (13) of a pull-off device (12) provided opposite the cutting device (11), and removed at right angles to the direction in which the bundle (1) is transported.

Abstract: A tamper evident closure and package having a container (10), a resealable, substantially rigid closure (12) for closing, opening and reclosing the container (10),. color changing means (32a in Figures 1-6) which effect a color change upon stretching, and coacting mechanical means (24, 36,44 and 46 in Figures 1-6) for uncapping and recapping the closure 10 and for stretching the color changing means (32a) which clearly and unequivocally indicate the condition of the package, e.g., open or closed.Where legends, or other well defined indicia, indicating opening is desired, the color changes can be localized in the skirt by providing thin sections (32a) which stretch preferentially and adjacent thicker sections (38) which remain substantially unstretched. The thin sections (32a) for example can be a legend, or alternatively the thick sections (38) can be the legend while the thin sections (32a) provide a suitable background.The colour changes employed by the invention can be accomplished by such phenomena as stress whitening inherent in various plastic materials. Alternatively, the color changes can be accomplished by mechanisms such as the use of encapsulated staining or coloring agents incorporated in a suitable matrix.

Title: Feeding device for liquid metal with temperature control in the continiuous casting of tubes
Inventor: PIERREL MICHEL
IPC: B22D11/04
Filed: 1985-11-11
Granted: 1988-07-07
Abstract: In a continuous vertical ascending casting installation for iron pipes T, graphite elements 3 defining a molten metal feed chimney 28, a die and coaxial core arrangement 13, 14 and an expansion vessel 16 are mounted under a cover 2 of an electric furnace 1. In use these graphite elements are immersed in a bath of molten metal contained in the hearth area 7 of the furnace, to thus enable precise temperature regulation and control. The outer surface of the die 13 is surrounded by a water cooling jacket 18, and the level of molten iron in the hollow cavity 25 of the core 14 is varied by the expansion vessel 16, to provide even finer control of the temperature gradient within the annular casting space. The overall arrangement is thus similar to a double boiler.

Abstract: A retortable, hydraulically solid, sealed package (10) containing a liquid or semi-liquid food product (24) comprises a thermoplastics container (12) formed by a thermo-forming process and a heat-shrinkable thermoplastics closure diaphragm (20). The closure diaphragm is heat-sealed to a rim (18) of the container after the headspace above the product has been evacuated, and is subsequently subjected to external pressure so as to be non-elastically stretched and made to lie wholly in contact with the enclosed product. When retorted (e.g. for sterilisation) the package suffers no visible deformation of the container (12), despite the considerable volume shrinkage of the container which may occur. The loss of volume caused by this volume shrinkage is accommodated by a reduction in the concavity of the diaphragm (20) caused by a corresponding heat-induced shrinkage of the diaphragm material. The diaphragm continues to exhibit a pleasing, smooth or smoothly curving surface, and the retorted package has a consumer-acceptable appearance.

Abstract: In a trunk circuit for digital signals, a digital subtracting circuit (3a) and an adaptive transversal filter (7) are inserted in a shunt branch between the transmitting path (6) and the receiving path (19). On the trunk circuit (6,19), digital signals are transmitted in the original frequency band from 0.3 to 3.4 kHz. A direct voltage or a digital sweep or noise signal in the original frequency bands 0 to 0.3 and 3.4 to 4 kHz, which are generated in the digital additional-signal generator (15a), are superimposed on such a received signal via a digital adding circuit (11a). This prevents the coefficients from escaping from a predetermined band. When analog/digital and digital/analog converters are inserted for digital operation of the adaptive transversal filter (7), connection to analog trunk circuits is also possible. These echo compensators are used, in particular, in international gateway exchanges. <IMAGE>
