Abstract: A system for resetting a cache in a first device connected by a multilinelink to a memory in a second device. A transceiver in the first element connects to one end of each of the link lines and a transceiver in the second device connects to the other end. The transmitter in the first device transceiver is disabled in response to a failure of the transceiver to receive messages from the second device. The transmitter in the first device transceiver also selectively sends a reset sequence to the receiver in the second device. A detector detects when all of the receivers in the second device have either received a reset sequence or have detected that a transmitter in the first device is disabled. The detector sets a latch in response, representing that data in the second device cache is invalid. Optionally, the second device has responders which send responses over the link lines indicating receipt of a reset sequence.

Abstract: A manifold assembly for feeding dough through a plurality of dies simultaneously under substantially equal pressure, includes a longitudinally-extending manifold having an inlet end for receiving dough under pressure, an outlet end defining a plurality of extruder dies, and a top, a bottom and sides connecting the inlet and outlet ends. A chevron-shaped dough guide intermediate the inlet and outlet ends distributes the dough to the sides thereof, the guide being configured and dimensioned to distribute the dough to the dies simultaneously under substantially equal pressure. Preferably, the manifold top is concave, and the guide does not extend to the concave top, so some of the dough can pass between the guide and the concave top.
