    摘要: The invention relates to a process for the production of fiberboards from coarse wood particles and isocyanate as binder, in which the wood particles are heated under excess water vapor pressure and simultaneously comminuted to fibers which are then delivered with expansion to a drier by means of a blowing pipe, and dried in the drier.

    摘要: To place superposed tape reels (14, 15) located in a cassette (10, 11) in a tape receiver (2) of a tape transducer system, which includes means to pull out tape from the cassette for threading in the system (see U.S. Pat. No. 4,254,922), a lever and cam system (32, 33, 34; 16, 31, 40, 41) is provided in which a cam follower (31) is located on the housing (11) of the cassette to engage a cam track (40) in a transfer lever (32) secured to the receiver. The transfer lever (32) has a second cam track (41) which is spaced farther from the pivot point (35) of the lever, the second cam track engaging a pin (16) coupled to a slidable carrier plate (12) in the cassette, and supporting the reels (14, 15) therein. Upon insertion of the cassette in the receiver, the cam follower (31) engages the cam track (40) of the transfer lever which, by lever action multiplication, upon engagement with the pin 16, will pull the carrier plate (12) out of the cassette, thus removing the reels from the cassette housing (10, 11). An ejection lever (33) is connected to the transfer lever (32) by a lost motion to provide for ejection, without interfering with insertion.
