  • Patent number: 4333484
    Abstract: An improved smoking material affording reduced particulate matter and puff count yet having the flavor and aromatic qualities of natural tobacco, which comprises cellulosic material having incorporated therein a metal salt from the group consisting of calcium salts, magnesium salts, iron salts, and aluminum salts of various organic or inorganic acids. A process for producing such a synthetic smoking material is also disclosed. The process preferably comprises forming an aqueous slurry of the cellulosic material, preferably in the form of loose and slightly beaten cellulose fibers, adding the metal salt to the slurry, casting the same and thereafter drying, conditioning and slitting or cutting the resulting sheet to produce a low tar filler material. A preferred embodiment of the invention resides in foaming the slurry prior to casting the same to form an expanded product.

  • Patent number: 4301817
    Abstract: A process for treating tobacco to reduce the delivery of various gas phase components, during combustion of tobacco products is disclosed. The process comprises contacting tobacco material with an aqueous solution to form a tobacco extract. After separating the extract from the fibrous tobacco portion, the extract is treated by an ionic extraction means such that nitrate ions are extracted while the potassium ion content of the extract is left substantially intact. The treated extract may then be recombined with the fibrous tobacco products. Such products exhibit reduced delivery of nitrogen oxides, HCN and CO during combustion.

  • Patent number: 4296804
    Abstract: A heat exchanger element is provided with small-bore copper tubing jacketed with perfluoroalkoxy resin wherein the ends of the jacketed copper tubing are each telescoped over the end of a stainless steel nipple having a raised shoulder at its end and an annular groove adjacent thereto. A stainless steel ferrule surrounding a sleeve of polytetrafluoroethylene overlies the joint and for a short distance to either side and is contracted particularly in the region of said nipple groove to squeeze the copper tubing thereinto behind said shoulder. This interlocks the tube with the nipple and establishes a fluid-tight seal between the ferrule, the nipple and the metal tube. The nipples are joined to headers or manifolds by welding or in similar manner.

  • Patent number: 4278696
    Abstract: The invention relates to a process for deacidifying a coffee extract without the introduction of foreign products by selective absorption with a natural material, chitosan. In this process, the extract is contacted with chitosan in divided form and the deacidified extract is collected after separation from the chitosan. Preferably the coffee extract is contacted with chitosan for 5 to 30 minutes at a temperature from 10.degree. to 80.degree. C. and in ratios (extract/chitosan) of from 15 to 400 ml per gram. The chitosan may either be suspended in the coffee extract, or the coffee extract may be percolated through a column filled with chitosan.

  • Patent number: 4277250
    Abstract: A method for detecting occult blood in aqueous samples of human specimens, particularly aqueous suspensions of fecal matter is disclosed. The method comprises acidifying an aqueous test sample, which in the case of fecal matter has been treated with lysozyme to clear the suspension; separating the liquid and solid portions of the test sample and passing the acidified liquid portion through an electro-negatively charged membrane; thereafter removing residual test liquids from the membrane; treating the membrane with a peroxidase indicator and observing the development of color on the treated membrane surface. A method for quantifying occult blood is also disclosed which comprises subjecting an aqueous sample to the disclosed detection method and comparing the color developed with a standardized scale reflecting colors developed by treating samples containing known incremental quantities of hemoglobin in accordance with the detection method of the invention.

  • Patent number: 4274427
    Abstract: Through interaction with the pectinaceous materials of tobacco smoking products, increased filling power of tobacco constituents is accomplished, in accordance with the present invention, by means of maintaining the tobacco, usually in shredded form, in an expanded form by applying, in solution thereto, multivalent metal and organic acid salts, especially those salts found in the hydrated form. The multivalent salt additives cause the pectinaceous materials of the tobacco to retain the expanded bulk volume of the tobacco.

  • Patent number: 4273791
    Abstract: A process for making fried taco shells. Disc tortillas are formed from a sheet of ground corn masa dough, and the formed disc tortillas are passed laterally through a heated baking oven on laterally moving open web support means in successive, appreciably longitudinally spaced transverse rows, each such row including a plurality of the tortillas. The baked tortillas are transferred in the aforesaid row arrangement through an elongated steam chamber and exposed to low pressure steam in the chamber for a time period of about a few seconds to about a few minutes. The steam exposure effects tempering and moisture equilibration in the tortillas. The tempered tortillas are transferred into and through deep fat frying apparatus.

  • Patent number: 4271201
    Abstract: Cheese is produced by a process wherein milk is subjected to partial ultrafiltration, heat denatured serum proteins are added to the milk before or after ultrafiltration, the milk is coagulated to form a curd wherein 1/4 to 1/2 of the total serum proteins contained in the curd are the added heat denatured proteins, and the curd is drained to produce curd containing a total amount of serum proteins substantially equal to the total serum protein content of the starting milk. The addition of heat denatured serum proteins overcomes a problem of alternation in the normal ripening cycle of cheeses produced from ultrafiltered milk containing an increased quantity of soluble serum proteins.
