Abstract: Fibers to be introduced into a mixture are initially pelletized or granulated at a compacting station. The pellets or granules are then transported to a user station where they are stored, and then re-fiberized as required ready for use and introduced into a mixer where they are mixed with other ingredients to provide a mixture with the required properties which is then ready for delivery.

Abstract: A window assembly has a latch assembly of enhanced strength. The latch assembly is mounted to the frame of the window assembly. A latch member is biased by a torsion spring towards a non-latching position, a latch-lock member is biased by a second torsion spring towards a non-locking position. The latch member engages a striker pin mounted to a base wall to secure the window in its normal, closed position. The latch-lock, latch member and striker pin are held together by the torsion springs and a series of detents on the latch-lock member and the latch member. A release bar is hingedly mounted to the latch assembly and moveable from a normal, closed, non-releasing position to an open, releasing position. Operation of the release bar forces a connection to actuate a trip lever, which in turn forces a latch-lock to rotate, sequentially disengaging the latch-lock detents from the latch member detents, thereby disengaging the latch member detent from the striker pin, allowing the window to open.
