Abstract: A B S T R A C T    USE OF ANTIGENIC SUBSTANCES FOR THE PROPHYLAXIS OF      TREATMENT OF DISORDERS OR DISEASES WITH THE GASTROINTESTINAL TRACT Of ANIMALS AND HUMANS            The invention refers to the use of antigenic substances for the prohylaxis or therapy of disorders and diseases with the gastrointestinal tract of animals and humans.            Disorders and diseases with the gastrointestinal tract of animals and humans, for instance, diarrhea, peptic ulcers diseases or cancer represent a worldwide serious, economically significant problem. It could be shown that the immunological mechanisms have a protective effect in the gastrointestinal tract of animals and humans. Antigens being present in the food induce the above-mentioned protective mechanisms when the organism has already been immunized with these antigens.            A preferred use of antigenic substances is for the prophylaxis and therapy of peptic ulcer diseases in humans. Furthermore, these antigenic substances are especially suitable for the breeding of young cattle when the food is changed within the first weeks of life.

Title: Rotor temperature control and calibration

Granted: 1992-10-06
Abstract: ROTOR TEMPERATURE CONTROL AND CALIBRATION                 ABSTRACT OF THE DISCLOSURE To enable centrifuging to occur at precisely determined sample temperatures, a method of centrifuge calibration which permits rapid and accurate refrigera-tion of the rotor containing the sample is disclosed.          A rotor with sample to be centrifuged is placed within a centrifuge can.   Temperature of the radiometer Tra, and temperature of the surrounding refrigerating can Tc is determined at a first time, t0.  Thereafter, and at a second time t1, temperature of the radiometer Tra, and the temperature of the surrounding refrigerating can Tc are equilibrated.  The temperature excursion between t0 and t1 for the temperatures of the radiometer Tra and the temperature of the refrigerating can Tc are measured to yield respective .DELTA. Tra and .DELTA. Tc.  The radio of .DELTA. Tra/.DELTA. Tc is taken to give a constant which comprises the view factor from the radiometer for the particular shape of rotor and the surrounding can.  Thereafter, the temperature of the rotor Tr will equal the tempera-ture of the radiometer plus the temperature of the radio-meter minus the temperature of the refrigerating can Tc times the determined view factor.  It is thereafter possible to maintain a large temperature differential between the refrigerating can and the rotor and bring the rotor (and necessarily the sample) rapidly to a precise temperature where centrifuging can rapidly follow.
