Title: Method for producing of dietetic mayonnaise and product made bay them
Inventor: HINEVIC EVGENIJ
IPC: A23L27/60
Filed: 1996-07-30
Abstract: The invention refers to the food industry, specifically to the production of diet mayonnaise. The offered mayonnaise production method differs from the ones used so far, by its considerably improved dietary, organoleptic and rheologic qualities, which result from abandoning the use of an emulsifier of animal protein origin. A new mayonnaise producing technology is used, which involves pasteurization at 60 to 65 degrees C temperature for 20 to 25 minutes, and emulsification and homogenization at 1.5 to 2.0 MPa pressure, which permits the use of a natural emulsifier (in this case, a starch acetyl derivation diadipate, xanthene and guergrain flour mixture), and as a balancer milk protein concentrate is used. To improve the taste quality and aroma, one of the seasoning dressings are used: extract of dill, parsley or celery, milled black peppers, cumin, dried garlic or garlic salt, powder of dried mushrooms, horseradish or laurel oil.

Abstract: 1,222,554. Detecting signals between amplitude limits; television; cathode-ray tube display. BOFORS A.B. 7 March, 1968 [3 April, 1967], No. 11237/68. Headings H3T, H4F and H4T. A television receiver has means for brightening or darkening that part of the image which is within a predetermined amplitude range, said means comprising a first amplifier indicating when the video signal is above a first level, a second amplifier indicating when it is above a second level, the brightening being effected when the first indication and not the second is present. If the video signal input at I rises above a negative threshold determined by resistors R18, R19, a comparator transistor T3 becomes conductive cutting off T4 and thus through R17 changes the state of a Schmitt trigger T8, T9. If the input rises above a positive threshold determined by R21, R24, a comparator transistor T6 is cut off rendering T7 conducting and thus causing T5 to short the input to the trigger which accordingly restores to its initial state. Diodes D11 and D12 limit the input to the two comparators. The input signal is applied to input I via an operational amplifier (Fig. 3, not shown) arranged to enable the D.C. level of the input signal to be varied so that different regions of the signal amplitude range fall within the range between the positive and negative thresholds. The circuit is described as used in a television system (Fig. 1, not shown) for scanning the human body to produce a thermographic display and for super-imposing peak a white or peak black signal upon the video input to CR tube when the temperature is within the aforesaid range (Fig. 1, not shown). A mirror scanning system directs the image on to an infra-red sensor of I n S b  maintained at the temperature of liquid nitrogen.
