Abstract: A container has a layer structure, comprises at least two compatible layers, integrally bonded together, one layer being formed of a substantially rigid pla­stic material, to allow said layer structure to be used or formed according to mechanical properties of said one layer. The other layer is formed of a sub­stantially flexible plastic material to allow said layer structure to keep tightness properties of said flexible plastic material when being used or formed according to said properties of said one layer. This layer structure fulfils the three following condi­tions:
     a) to maintain a shape into which it is brought,   b) to allow for frequent change of this shape and   c) to maintain tightness even on frequent change­ments of that shape.

Abstract: In a digital radio transmission system for transmitting independent dual data by using cross polarization, an interference canceller detects cross polarization interference either directly or indirectly. An interference compensating signal is generated and applied to the main signal to cancel the interference element. In a case where no interference element is present, deterioration of cross polarization discrimination from an interference cancelling circuit is prevented by first determining whether an interference element actually exists and applying the interference compensating signal only when it does exist. The interference compensating signal can be attenuated based on the value of interference element so as to prevent undo deterioration of the cross polarization discrimination when the interference element is minimal.

Abstract: The device has separating elements (1) attached at regular distances to a circulating endless V-belt (21), which elements single out the note to be counted at the counting point (34) and hold it temporarily in the counting position. The notes stacked into a packet rest upright on edge on a packet holder (35 to 38) which is displaceable transversely to the direction of movement of the separating elements (1). The separating elements (1) have a suction area (2) which sucks in an upper edge strip of the note to be counted during the straight-line passage past the counting point (34) and is constructed to be curved in such a manner that the edge strip is subjected to a torsional twist whilst lifting away from the remaining packet. Due to the restoring spring force against torsional deformation which is a characteristic of the notes, separating errors are reliably prevented in this manner. In the sucked-in counting position, the singled-out note is scanned by an optical counting device and counted and subsequently passes behind the next separating element (1) behind which it becomes engaged. …<IMAGE>…

Abstract: An electrical connector of low-insertion force type comprises a male plug (1) having pin terminals (2) and a female socket (3) having contacts (5). Each pin terminal (2) has straight slant opposite surfaces (6, 7) extending from the opposite ends (D, E) of its flat nose (B) at a same angle. The flat nose (B) is positioned with its center somewhat beyond the center axis (C) of the pin terminal, thereby placing the opposite slant surfaces (6, 7) asymmetrical with respect to the center axis (C) of the pin terminal. Thus, the insertion force of each pin terminal (2) reaches its peak value on one side of the pin terminal earlier than on the other side as shown at S₁ and S₂ in Fig. 4. This permits substantial reduction of the insertion force overall. The straight inclination of surfaces (6, 7) can be easily shaped with precision. This facilitates mass production of pin terminals (2) of the same insertion force characteristics.
