Abstract: A high isolation RF switch for launching a selected one of two RF signals into a slabline transmission line structure has a three switch configuration—a pair of input switches coupled to corresponding input ports and a transition switch coupled to an output port via a slabline transmission line. The input switches select one of the input ports for coupling to the transition switch, and the transition switch couples the selected input port from the input switches to the output port. A grounded conductor is situated between the input ports in a cavity of a housing within which the high isolation RF switch is located to provide isolation between the input ports. Additional isolation between the input ports is provided by coupling the non-selected RF signal to ground, either by grounding the non-selected input to the transition switch or the non-selected input port.

Abstract: A novel starch-based texturizing agent, methods of manufacture and food formulations containing the texturizing agent. The texturizing agent comprises an insoluble microparticle (e.g., titanium dioxide), a gum (e.g., xanthan gum) and starch (e.g., pregelatinized starch) in the form of a complex in which the insoluble microparticle has been stabilized or entrapped therein. The texturizing agent can be used in low fat and fat-free foods, including mayonnaise, edible spreads such as margarines, salad dressing, mousse, cottage cheese dressing, sour cream, ice cream, yogurt and cream cheese.

Abstract: The present invention pertains to a novel starch-based opacifying agent, to methods of manufacture and to food and non-food formulations containing the opacifying agent. The starch-based opacifying agent comprises an opacifier (e.g., titanium dioxide) and starch in the form of a complex in which the opacifier has been stabilized or entrapped therein. The opacifying agent can be used in low fat and fat-free foods and beverages, including coffee creamer, cottage cheese dressing, nutritional beverages, mayonnaise, sour cream, ice cream, yogurt, salad dressing and other foods and beverages that need to be opacified. The opacifying agent can also be incorporated into non-food formulation, such as cosmetics, creams and lotions.

Abstract: A fat substitute is disclosed which comprises water-dispersible macrocolloid particles composed of carbohydrate materials which particles have a substantially spheroidal shape and a specific particle size distribution effective to impart the substantially smooth organoleptic character of an oil-and-water emulsion.

Abstract: Non-fat and reduced fat whipped frozen dessert products wherein part or all of the milk fat, vegetable fat or oil ordinarily incorporated therein is replaced by a proteinaceous macrocolloid of, e.g., denatured whey protein particles or particles having a core of casein surrounded by a shell of denatured egg white protein. Illustrative embodiments include non-fat ice cream analog products having reduced calorie content, enhanced food value due to increased protein content, and possessing the physical and organoleptic character of full fat ice creams. The egg white protein/casein particles can be used also in sauces, dips, spreads, icing and cream pie fillings.
