Side 11 - ... if it consists in whole or in part of any filthy, putrid, or decomposed substance, or if it is otherwise unfit for food; or (4) if it has been prepared, packed, or held under insanitary conditions whereby it may have become contaminated with filth, or whereby it may have been rendered injurious to health...
Side 4 - If it consists in whole or in part of a filthy, decomposed, or putrid animal or vegetable substance, or any portion of an animal unfit for food, whether manufactured or not, or if it is the product of a diseased animal, or one that has died otherwise than by slaughter. SEC. 8. That the term "misbranded...
Side 8 - The maintenance of sanitary conditions requires extermination and exclusion of rodents, inspection and sorting of raw materials to eliminate the insect-infested and decomposed portions, fumigation, quick handling and proper storage to prevent insect development or contamination, the use of clean equipment, control of possible sources of sewage pollution and supervision of the conduct of those who prepare foods so that acts of misconduct may not defile the products they handle.
Side 42 - ... suitable material for the target of an x-ray tube. Circulation of water or oil in the interior of the anode is an effective method of carrying away the heat. In the absence of provision for liquid cooling, the use of copper for the main body of the anode provides high heat conductivity, while radiating fins on the end of the anode outside the tube transfer the heat to the surrounding oil or air. The focal spot should be as small as conditions permit, in order to secure the sharpest possible definition...
Side 8 - ... who prepare foods so that acts of misconduct may not defile the products they handle. Fumigation of commodities already infested with insects will not result in a legal product since dead insects or evidence of past insect activity are objectionable. Fumigation should be employed where necessary, to prevent infestation.
Side 44 - A dark spot, corresponding to the projected position of the void, will appear on the film when it is developed. Thus, a radiograph is a kind of shadow picture — the darker regions on the film representing the more penetrable parts of the object and the lighter regions the more opaque.
Side 9 - ...if it consists in whole or in part of any filthy, putrid, or decomposed substance, or if it Is otherwise unfit for food...
Side 43 - ... shows the essential features in the exposure of a radiograph. The focal spot is a small area in the X-ray tube from which the radiation emanates. In gamma radiography, it is the capsule containing the radioactive material that is the source of radiation (for example, cobalt 60).
Side 42 - ... making the angle between anode face and central ray small, usually 20 degrees, the effective area of the spot is only a fraction of its actual area. With the focal area in the form of a long rectangle, as shown, the projected area, in the direction of the central ray, is square. As will be seen later, different voltages are applied to the x-ray tube to meet the demands of various classes of radiographic work. The higher the voltage, the greater the speed of the electrons striking the focal spot....
Side 38 - The court also declared that it was his opinion that the statute is largely intended to protect those consumers who would not be in a position to observe the defect in the food.
