Abstract: The disclosure relates to the recognition of an objective known as an IFF or "Identification Friend or Foe" system. In the interrogator unit of the IFF system, the signals received undergo processing operations that take account of the characteristics of the antenna and enable the useful information to be separated from the disturbances. In order to be able to use an electronic scanning antenna in spite of the fact that it has characteristics which vary with the training angle, hence with the direction in which the objective is located, the processing operations to be performed are designed for different training angles, the characteristics of these processing operations are memorized and the processing operations are performed as a function of the training angle.

Abstract: The invention relates to a machine for packing articles of different sizes which is accordingly intended to use containers that vary in their dimensions and particularly in height.It is characterized in that it includes a working plane 20 and a reference plane 22 that are substantially perpendicular to one another, and an ascending ramp 24-105-106 extending from one to the other, movable devices 23, 23a kinematically connected to a motor 45, guides located on the path that the closure panels 6 must follow in the course of the displacement of container-article sets 1, at least one pressure element 27-54 having a smooth active base 29, mounted to be movable perpendicular to the working plane 20 and elastically urged toward it, at least one pressure element 30-60 having a smooth active face 34, mounted to be movable perpendicular to the reference plane 22 and elastically urged toward it, and means 70 to 72 intended for the fixation of panels 6 of containers 1 equipped with their contents A.

Abstract: The described process involves the production of a product comprising a fibrous substrate to which an adhesive with long-term effect and a removable protective strip are applied in order to permit use of the adhesive to be deferred. The process is particularly useful with substrates whose surface to which the adhesive is applied contains irregularities. The adhesive is heated to a temperature at which it becomes paste-like and readily flowable and is brought to an opening situated above a plane surface on which the substrate has been placed. The adhesive is then caused to flow simultaneously with a relative movement between the substrate and the opening to be deposited on the substrate as a strand that is preferably continuous. The temperature of the adhesive on the substrate is then lowered in order to increase its viscosity until it becomes paste-like just prior to the point of turning solid.

Abstract: The package is of the type comprising two lateral symmetrical flaps 12 and 13 which can be applied against one large surface of the package. An adhesive tape 26 is provided at least on the flaps 12 and 13. Tongues 18 and 19 are used for wedging action with respect to the packaging of objects. In another embodiment notches 30, 31, 32 and 33 are used into which the flaps 12 and 13 can be bent. Application for packaging objects of different height.

Abstract: A phenolic resin based laminate material which can be cross-linked by acid catalysis, endowed with a reinforcement, comprising at least two surfaces and having on at least one of its two surfaces at least one additional nonphenolic resin-based layer is disclosed.In accordance with the invention, the additional layer in contact with the phenolic resin is obtained from a formula comprising an unsaturated polyester resin, a cross-linking solvent of said resin, possibly one or several other additives, at least one of the main components having a formula comprising hydrophilic centers in a number at least equal to the number of non-saturation centers in the polymeric chain of the resin.

Abstract: A package comprises a strip (1) of corrugated cardboard to be wrapped around objects (A) placed on its inside surface. It is provided with two transverse flaps (13, 14) in face-to-face relationship and attached to the inside surface of the strip (1) on two side bands (8, 9) which extend from its longitudinal edges (2, 3) over a distance x, parallel to the longitudinal edges (2, 3) of the strip (1). The strip (1) comprises an end panel (7) which is cut in line with a transverse fold (6) in its central part, meaning that part lying between the two side bands (8, 9). The panel (7) is divided into two flaps (13, 14) by a median longitudinal slit (15). The panel (7) may be folded over the inside surface of the strip (1) by bending it about the transverse fold (6) and fastened to the side bands (8, 9) of the strip (1). The strip (1) is advantageously glued to itself in the transverse direction and to the two flaps (13, 14) when folded against an article in the package.
