Abstract: Method and apparatus is described for the microbiological production of single-cell protein making use of ethanol as a base material thereby allowing the protein produced to be used for human consumption. The process involves the cultivation of ethanol activated yeasts at temperatures between 20 DEG and 40 DEG C. under aerobic conditions in a fermentation column containing a dilute nutrient medium having a pH value in the range 2.5 to 5 containing nutrient salts, acid phosphate and nitrogen-containing substances in which the nutrient medium is continuously circulated into and through and out of the fermentation column and at each re-entry into the column is introduced tangentially into a zone which is oxygen enriched using oxygen gas molecules in the range 1 to 7 mu to form a bio-mass which can be separated and dried to form a protein product. The formation of a large gas bubble in the fermentation column is prevented by carrying the process out under a positive pressure and a gas extraction stage is provided immediately beyond the column. Pure oxygen or oxygen-enriched air may be used. In apparatus for performing the above method the pump for circulating the medium from the heat exchanger to the column is located in a conduit between the heat exchanger and the column.

Patent ES-486495-A1 (ES)
Title: Switching apparatus for a group of elevators or the like
IPC: B66B1/20
Filed: 1979-11-30
Abstract: A switching apparatus operatively associated with each elevator of an elevator group operated by means of a collective control and individual travel control serves the purpose, for instance in hospitals, of switching one or more elevators from one control mode to the other control mode. The switching apparatus comprises four series connected switching stages formed of digital logic or switching elements. By activating one of the key switches of the first switching stage there is initiated the switching operation to the relevant other operating mode, and there are generated signals which eliminate the elevator which is to be switched over from the storey call allocation. Upon arrival of an input information or signal which signals the operating state "free" of the elevator which is to be switched over, there is accomplished allocation to the desired operating mode by freeing the correlated door control by means of output signals produced in the second switching stage. A timing element of the third switching stage, after expiration of a control time, prior to allocation at the desired operating mode, generates a signal interrupting the cabin call transmitter supply. After servicing the last call which is located in the momentary travel direction of the cabin, the fourth switching stage produces a signal which extinguishes the still stored cabin calls and a signal which blocks the door closing operation until emptying of the elevator cabin.
