Abstract: A disc record manufacturing method and apparatus wherein a record pressed at a press station is transported to a trimming station where flash is trimmed from the record with the trimmed record then being transported beyond the trimming station. While the record is maintained in a horizontal attitude during the pressing and trimming operations, when transported beyond the trimming station the record is pushed along guides which guide the record in such a way that it changes from its horizontal attitude to a substantially upright attitude in which the record is permitted to fall downwardly. An envelope is held with an open upper end thereof situated in the path of downward falling movement of the record so as to receive the latter, and then the envelope with the record therein is released to drop to a stacking guide where the envelope with the record therein remains in an upright attitude while a horizontal stack is formed from a series of envelopes with records therein.

Abstract: Continuous control of biosynthesis process conditions on the basis of measurable quantities in the off-gases from the process and calculated quantities derived from said measured quantities provides for optimization of reaction conditions with respect to maximum output rate of selected product. Where the selected product is a mix of cell mass and ethyl alcohol ranging from virtually all cell mass with negligible alcohol to the maximum alcohol content which the cell can tolerate, optimization depends on maintaining the ratio of carbon to nitrogen in the nutrient feed at a level appropriate to the desired product mix. The calculated quantities, including the time derivative of the rate of oxygen uptake, are used for essentially continuous control of the rates of feed of individual nutrients and other selected essential variables as a means of optimizing the process.
