Abstract: Security inspection apparatus designed for the safe, efficient and rapid inspection of products to detect the presence of objectionable X-ray detectable items. The apparatus comprises a source of continuous X-rays of sufficiently low intensity that conventional photographic film is insensitive thereto, a fluoroscopic screen, a television camera adapted to transmit electrical impulses which provide a visual picture of the images on the fluoroscopic screen to a television monitor and means for intensifying the electrical impulses transmitted by the camera so that the image on the monitor is clearly visible. The apparatus also comprises means for continuously moving products such as baggage between the X-ray source and the screen at a uniform speed within a shielded compartment so that a continuously changing visual picture of the contents of the baggage is displayed on the monitor, providing a three-dimensional picture of each detectable item in the baggage and an indication of its relative location therein.

Abstract: Pneumatic nebulizer for uniformly dispersing variable amounts of flowable liquid in a gas to form a stable dispersion having the appearance of a natural fog and consisting essentially of liquid particles having a maximum particle size below about 20 microns diameter and having an average particle size well below about 10 microns diameter suspended in said gas. The liquid is forced at a variable rate into a gas flow, at an angle thereto, through an orifice having a width which is variable under the effect of gradual changes in the force of said gas and/or of said liquid to stress the liquid prior to contact with the propellant gas, and is contacted with the propellant gas as it emerges from the orifice in stressed condition for conversion into a stable dispersion having the appearance of a natural fog.

Abstract: A dry duplicating method comprising the steps of pressure-imaging a continuous master web with images capable of exuding liquid ink under the effects of contact pressure such as roller pressure and collecting the imaged master web on a roll for duplicating use. The master web is such that at least one surface is receptive to the pressure-applied images but neither surface is capable of absorbing the liquid ink to any substantial degree. The imaged web is duplicated by continuously bringing it into surface contact with an ink-absorbent copy web while pressure is applied to exude the liquid ink from the master images onto the copy web to form a duplicate copy, after which the web is continuously rolled up on another roller for reuse.
