Abstract: A carpet cleaner for cleaning carpets includes a foam generation unit, roller brushes and a heated air drying mechanism. The foam generation unit uses multiple stages of foam generation for creating a very fine foam which is applied to the carpet. A suction device removes excess foam from the carpet after the brushes have gone over the carpet. Finally, heated air is blown across the carpet after the suction device has removed the excess foam. The carpet is cleaned, dried and ready for immediate use.

Abstract: Disclosed is nitrogen-containing polysaccharide substantially free of units having a molecular weight below about 5,000, said nitrogen-containing polysaccharide having been extracted from Coriolus versicolor (Fr.) Quel., substantially all polymer units having a molecular weight below about 5,000 having been removed therefrom, which exhibits antitumor and immunological activity.

Abstract: A method of restoring the immune response of a patient having a lowered immune response level is provided, in which the patient is given an effective amount of certain nitrogen-containing polysaccharides derived from Coriolus versicolor (Fr.) Quel, where the polymer units having a molecular weight of below about 5,000 have been removed therefrom.

Abstract: Disclosed is a method for producing a frozen-food which comprises: the step of forming an ice-capsule, in which the food, initially at room temperature, is chilled with a freezing medium of -80.degree. C. to -100.degree. C. so as to form an ice-capsule surrounding the food within 15 minutes; the step of mild chilling, in which the food is chilled in an environment of -25.degree. C. to -35.degree. C. so that the temperature of the center of the food becomes about 0.degree. C.; the step of quick chilling, in which the food is chilled with a freezing medium of -80.degree. C. to -100.degree. C. so that the temperature of the center of the food becomes about -6.degree. C. or lower; and the step of freezing-storage, in which the food is chilled at a relatively mild temperature for a period of time and then stored at a temperature of -18.degree. C. to -20.degree. C. until consumed.

Abstract: Disclosed in this invention are protein-bound polysaccharides having antitumor activities. The polysaccharides have molecular weight within a specified range and present a pattern of color reaction peculiar to the saccharides as well as a pattern of color reaction characteristic of amino acids and peptide bonds. The proton nuclear magnetic resonance spectra of the polysaccharides show peculiar absorption bands. The ratio of the polysaccharide portion to protein portion in the polysaccharides is within a specified range. The protein-bound polysaccharides can be obtained by extraction of the mycelia and/or fruit bodies of fungi belonging to Coriolus of Polyporaceae of Basidiomycetes.

Abstract: The fungi belonging to the Coriolus genus is first extracted with water or a dilute alkaline solution and then further extracted stepwise by using alkaline solutions with gradually increased concentrations to obtain a nitrogen-containing polysaccharide having an anti-tumor activity in a high yield.

Abstract: A reciprocating type tenderizer is driven by a rotary crank to enable higher operating speeds and much higher cutting edge velocities. The surface of the conveyor is maintained within 1-2 mm of the bottom dead center position of the cutting edges to provide more complete penetration and a torque limiter is provided for interrupting the conveyor movement during cutting. Novel cutting edge configurations are also provided which are suitable for a wide variety of meats.

Abstract: The fungi belonging to the Coriolus genus are extracted by using a dilute alkaline solution having a concentration within a certain specified range whereby the low molecular weight substances with molecular weight of less than 5,000 are obtained in there extract solution. These low molecular weight substances are separated from the extract solution to obtain a nitrogen-containing polysaccharide having excellent anti-tumor activity.

Abstract: Polysaccharides are produced by purifying a liquid extract of a mycelium of a strain of fungus species belonging to the class Basidiomycetes or the filtered broth of a cultured medium in which a mycelium of a selected strain of Basidiomycetes has been incubated; the polysaccharides exhibiting an anticarcinogenic activity in mice.

Abstract: An ultrasonic device for convergently radiating ultrasonic energy including a metallic ring vibrated to resonance by at least one electromechanical transducer fixed on the outer circumference of the ring, thereby to deliver high power ultrasonic waves from the inner circumference of the ring into the vacant center thereof.
