  • Patent number: 10252479
    Abstract: A resin barrier device (5) for an infusion tool (1) includes a tubular intermediate piece (15) having a first end (17), which is adapted for connection to a venting outlet (3) of an infusion tool (1), having an opposite second end (19) adapted to be connected to a ventilation line (7), and having a channel (27) surrounded by a pipe wall (25), which forms a fluid connection between the first end (17) and the second end (19), and a semi-permeable barrier wall (29) provided in the channel (27), which is arranged to let an airflow pass from said first end (17) to said second end (19) and to block a resin flow from the first end (19) to the second end (19).

  • Patent number: 5502965
    Abstract: A device is described for generating operating states characterized by dirences in height in actuators arranged in a matrix. In order to enable operating states which are characterized by differences in height to be produced in mechanical actuators in close matrix-type arrangement which are controllable selectively and independently from one another in a simple manner in a suitable device a reservoir filled with electroviscous liquid has an over-pressure chamber and a negative-pressure chamber and these chambers are connected via separate control ducts with hydraulic cylinders of the actuators, the connection to the two chambers of the reservoir being opened or blocked alternatively by the two control ducts of an actuator via a first electrode and a second electrode and a controllable center electrode common to both. The pressure variation formed in this way changes the vertical adjustment of a mechanical pin via an elastomer diaphragm.
