Inventor: COLE GARY B
IPC: H04Q11/04
Filed: 1990-12-07
Abstract: A line unit interface circuit used on line units in a line shelf of a digital loop carrier provides all of the logic necessary to access two subscriber lines to a line unit interface bus connected to common equipment within the line shelf.  Information received from the common equipment includes signaling data, configuration data and provisioning data, which is reconfigured and processed by the line unit interface circuit for controlling the subscriber line channels.          Configuration data from the common equipment is decoded to assign time slots on the line unit interface bus to the various channels serviced by the line shelf and to further provide for a timing offset between the transmit and receive strobes provided to each subscriber line circuit.  A flywheel circuit is used to prevent erroneous time slot assignment in the event of noise or interference on the line unit interface bus.

Inventor: LARSEN PETER
IPC: A21D6/00
Filed: 1990-07-11
Abstract: Leavened yeast dough products obtain a long durability in a frozen condition by omitting using in the preparation thereof fermentable carbohydrates, but the formation in situ of such fermentable carbohydrates satisfactory to leaven the dough is ensured by adding one or more amylases to the dough. Upon freezing the activity of the amylase ceases and the concentration of fermentable carbohydrates falls to such a low value that the proteinase forming activity of the yeast actually ceases. A possibly desired brown-coloring of the baked product may be ensured by the addition of amylases with an activity at a relatively high temperature.
