Title: Whey-protein recovery - by processing whey with yeast and processing soln after yeast separation
Inventor: KAUTZ JUN URT DIPL KFM
IPC: A23C21/02
Filed: 1972-08-02
Abstract: Processing of whey admixed with yeast for removing lactose by yeast-formation under simultaneous aeration, and then separating the yeast by centrifuging, is effected by using the whey in fresh condition or after a heat-treatment leaving the whey protein in original condition. Whey-protein is recovered by further processing of soln. after yeast separation, and can be freeze dried for further use, e.g. as addn. to diet foods for patients or diabetics, or in prepn. of protein-enriched milk, or mixed with wheat-gluten or fish-protein. Protein-uptake by yeast is prevented by adding urea and/or N-contg. salts and phosphates, together with yeast. The whey-protein and mineral salt-contg. soln. may be concd. in vacuo at 60 degrees C or by reverse osmosis. De-salting of conc. prod. is effected by ion-exchange, but pref. by dialysis, esp. by electrodialysis.

Title: Static converter with load current monitor and control - increases commutation frequency to handle rapidly-changing loadings
Inventor: POMPA JUN THOMAS NICHOLAS
IPC: H02M7/525
Filed: 1974-02-19
Abstract: The static converter has a pair of main thyristors alternately allowing current to pass to the load. A commutating circuit switches the capacitor through to an inductor which turns-off the conducting thyristor. The time between the commutating circuit becoming active and the switching-on of the non-conducting thyristor is equal to a stipulated time interval. The current through the load is measured by a small transformer. A circuit responds to rapid changes in this derived signal from the transformer and produces a control signal that reduces the previously-mentioned given time-interval so that the static converter is effective even with rapidly increasing loadings.

Title: Automatic tuning method for resonant circuits - is applied to frequency of H.F. signal when frequency is changed
Inventor: LISCHKA HANSJOERG
IPC: H03J7/16
Filed: 1974-04-29
Abstract: One resonant circuit is tuned, and the h.f. signal is within a certain frequency band. A motor mechanically coupled with the circuit tuning means is stopped when the resonant circuit frequency is equal to that of the applied h.f. signal. The tuning process is initiated by an external command applied to a logic circuit which then starts the motor in one of the two directions. A tapped part of an electric output variable (power, voltage, current) from the resonant circuit is rectified, differentiated and applied to a logic circuit. When this output signal is negative, the logic circuit reverses the motor, and when it is positive, the motor is allowed to run until it becomes zero.
