  • Patent number: 4031266
    Abstract: Dehydrated reconstitutable tomato beverage compositions are prepared by forming an aqueous admixture of tomato solids and gelatinizable starch materials, the starch materials to water ratio in the admixture being such that limited rupture of the starch granules occurs, whereupon the admixture is drum dried and ground to produce a powder which, upon rehydration, gives tomato beverages of viscosity, texture and taste comparable to conventional non-dehydrated tomato beverages.

  • Patent number: 4009291
    Abstract: A starch composition having lower hydroscopicity, lower bulk-density and better film-forming and holding properties than low D.E. dextrins comprising granule starches which have been hydrolyged to a D.E. of less than about 1 with little or no reducing sugars being present while retaining their granule structure and have thereafter been gelatinized.

  • Patent number: 4002096
    Abstract: This disclosure pertains to a novel wind instrument having a range of two octaves. Seven lettered note keys, starting with C, each can be individually depressed to produce a tone. An octave bar, when simultaneously depressed, produces the corresponding tone in the next higher octave. Scale programming buttons, when once depressed, select a sharp, natural, or flat tone which is now produced when depressing the lettered note key, in accordance with the composition's key signature. Means are provided to quickly reset the program by first making all lettered note keys natural and upon further simple manipulation, selection of the new scale program may be obtained. To avoid disturbing the program set by the scale buttons, a group of buttons provides tones in an accidental register which, upon their depression, will produce accidental notes not included in the main key.

  • Patent number: 3973052
    Abstract: The present invention provides stable aqueous hop extracts suitable for bittering beer which contain substantially no fixed hop seed oil. The hop extracts consists essentially of potassium isohumulate and between 16% and 72% by weight of water.

  • Patent number: 3970766
    Abstract: Volatile flavoring compounds such as acetaldehyde are fixed in low amounts by having the compound present in solution during the crystallization of sucrose. It is believed that the volatile flavors are entrapped as impurities within the crystal structure. The resulting compositions have excellent stability over a wide range of humidities, are soluble in both hot and cold water, and have application as flavor and aroma modifiers for foods.

  • Patent number: 3956508
    Abstract: Flowable powders are prepared containing a mixture of food flavoring ingredients, and particulates of expanded dextrin having a bulk density of from about 0.05 to about 0.30 grams/cubic centimeter, a dextrose equivalent of from about 5 to 15 and a moisture content of about 2% to 6%, and having sorbed in the dextrin particulates an aqueous alcohol solution to provide from about 30% to 60% by weight ethanol in the resultant ethanol-containing dextrin particulates. The powders are stable when hermetically packaged and are particularly qualified as alcoholic beverage forming compositions and flavoring materials since the ethanol-containing dextrin particulates readily dissolve in cold water to form clear low-viscosity, colorless liquids.

  • Patent number: 3956511
    Abstract: Flowable dextrin powders containing about 30 to 60% ethanol sorbed therein are prepared by sorption of an aqueous alcohol solution with particulates of expanded dextrin having a bulk density of from about 0.05 to about 0.30 grams/cubic centimeter, a dextrose equivalent of from about 5 to 15 and a moisture content of about 2% to 6%. The powders are stable when hermetically packaged and are particularly qualified as alcoholic beverage forming compositions and flavoring materials since the powders readily dissolve in cold water to form clear, low-viscosity, colorless liquids.

  • Patent number: 3956509
    Abstract: Flowable dextrin powders containing about 30 to 60% ethanol sorbed therein are prepared by sorption of an aqueous alcohol solution containing about 5 to 25% moisture with expanded dextrin particulates having a bulk density of about 0.05 to 0.30 grams/cubic centimeter, a dextrose equivalent of about 5 to 15, a moisture content of about 2 to 6%, a glucose content of less than 1% and trimer, hexamer and heptamer oligomers by weight of its total oligomer content of more than 50%. The resulting products are stable when hermetically packaged and are particularly qualified as alcoholic beverage forming compositions and flavoring materials since the powders readily dissolve in cold water to form clear, low-viscosity, colorless liquids.

  • Patent number: 3949092
    Abstract: The present invention provides a flavoring agent suitable for addition to fermented beer. The flavoring agent is an aqueous solution of water and potassium isohumulates substantially free from lupulones and fixed essential oils of hops. The invention also provides a method for flavoring beer by adding a hop extract consisting essentially of an aqueous solution containing between about 40% and 60% by weight of potassium isohumulates which are substantially free from lupulones and fixed and essential oils of hops.

  • Patent number: 3939944
    Abstract: The disclosure relates in general to an oil-mist lubrication system, and more particularly to the propagation of a mixture of oil-mist to bearings of a spindle, wheelhead, or the like by means of a blender-distributor unit. A first controlled amount of air from an air supply unit is fed through an oil-mist unit to produce a controlled high density oil mist. A second controlled amount of air from the air supply unit bypasses the oil-mist unit and is fed into an air chamber of a blender distributor unit. The high density oil mist is also fed into an oil-mist chamber of the blender distributor unit. A plurality of blending nozzles in the distributor unit extend from the exit side of the air chamber. A like plurality of tubes extend from the exit side of the oil-mist chamber of the distributor unit, each tube mounted coaxially within a respective nozzle whereby the blending area of the exit end of each tube within the nozzle produces a lower density oil-mist to be carried to the bearings.
