Abstract: An actuator is provided which comprises a cylinder within which are a piston (1), a piston rod (7) and a mechanical linkage arranged to transmit axial movement of the piston to the piston rod at a relative speed which decreases as the piston nears the end of its travel towards the piston rod. A rigid member constituted by a pivot disc (14) and link plates (16, 16a) is pivoted to the piston rod at a first pivot point. A link (17) is pivoted at a second pivot point (18) to the link plates and at its top end is pivoted to the piston (1). A pin (23) supported in the cylinder at an axial postion intermediate the piston and the piston rod end of the cylinder for transverse sliding movement is pivoted to or pivotally engageable within the disc (14) at a third pivot point. When the piston is at the far end of its travel from the piston rod the second and third pivot points respectively constituted by the pivot (18) and the pin (23) are both on the same side of the piston axis, whereas when the piston moves towards the piston rod, the second pivot point moves to the other side of the piston axis. In a preferred arrangement the pin (23) disengages with the disc (14) when the piston rod is at the far end of its travel.

Abstract: An external shaft rotary piston machine wherein pistons of a piston rotor run in engagement with a cavity of a circular cylindrical sealing rotor during a particular relative rotational position of the rotors, the cavity being substantially larger than necessary for passage of the pistons in order to avoid flow losses due to seal wedging flow and compression. In order to avoid overflow from the high pressure side to the low pressure side of the machine through the sealing rotor while the pistons move in the sealing rotor through the space defined by the cavity, a sealing effect is created by a leading edge and a trailing edge portion of the opening of the cavity of the sealing rotor moving along a leading and a trailing side surface of the pistons. This is effected kinematically due to the fact that the trailing edge of the cavity opening is displaced radially inwardly and that an edge portion extends from the trailing edge convexly relative to the peripheral surface of the sealing rotor.

Abstract: In order to form safety markings at a planar card made of a plastics material, which card may be used, for instance, as credit card, this card is built up from at least two parts. The inner border area between these two parts comprises a relief-like structure which is the carrier of the safety marking. In order to generate a watermark-like effect the upper part is made of a opaque plastic material and the other part is made of a transparent plastics material. When viewing through this card the areas of the opaque layer having the largest thickness appear as darker areas, whereby when viewing the same way the areas having a smaller thickness show a certain brightness. After being embossed the two parts of the thermoplastic material are joined to each other such that they cannot be separated such that no access from the outside is possible to this safety marking. Accordingly, an additional safety factor is arrived at in cards which can be used as money substrate, identification means or a license for any kind of access.
