Abstract: A surface of an object is coated with a uniform thickness of a photographic emulsion. In the coating method, there is utilized an apparatus which comprises a smaller substantially enclosed chamber which communicates at its upper end with a vertical open larger chamber. Jet streams of liquid emulsion droplets and an inert gas are introduced into the smaller chamber. By elutriation, larger droplets fall to the bottom of the smaller chamber and droplets sufficiently small in accordance with Stokes law pass into the larger chamber. Here, those droplets which are small enough according to Stokes law for the larger chamber rise to leave the larger chamber from its open end and droplets having a size large enough to descend according to Stokes law settle on the surface of an object positioned within and at the base of the larger chamber to form the emulsion coating on the surface.

Abstract: A silver bromide emulsion containing cadmium iodide and coated on a substrate is employed to produce a latent silver image thereon. This latent image is developed in a high-resolution pattern developer to produce a silver image which when heated to a temperature of 200* to 450* C. produces an image having an electrical conductivity closely approaching that of bulk silver. The high-resolution pattern developer results in a feltlike structure of silver wires which when heated at higher temperatures decreases in reflectivity.

Abstract: A method is provided for reducing measured data to representative coefficient values. The data relates to physical energy collected and measured by a physical sensor, and therefore, the measured data includes noise. In the method which may be carried out by programming a general purpose digital computer, the measured data values are first processed to remove the linear trend. The resultant values are then processed to provide the maximum number of coefficient values which represent the measured data values. A certain number of the set of coefficient values represent the portion of the measurements which is substantially noise, and may be eliminated. The method therefore includes a process for determining a number of coefficients of the total set which represent the measured data with minimum error where minimum error is defined as minimum stochastic uncertainty.

Abstract: What is disclosed is an optical scanner for reading bar codes. The scanner is designed to be held by hand and moved above and across the bar code which is printed on a suitable record substrate. The scanner is composed of a suitable casing containing lamps in the lower portion thereof which illuminate the bar coded record. The illumination is reflected through a unique aperture in the lower surface of the scanner and directed onto a light sensor arrangement such as a photocell. The code marks are in the form of code bars such as black lines separated by white portions. The code consists of "single" code bars and "double" code bars which are, in one embodiment, twice the width of the "single" bars. The aperture arrangement of the scanner is designed according to a scheme such that the resultant signal from the detection of a single bar will always be a known fraction, such as one-half, the amplitude of the signal produced by the detection of a double bar regardless of the changes in speed at which the hand-held scanner is moved across the bar coded record.

Abstract: A gelatin medium is stirred in a three-chamber container which includes a rotating paddle turning at an adjustable constant speed in the lowest one of the chambers. Potassium halide and silver nitrate solutions are added to the other chambers at a constant velocity by an ejecting system driven at an adjustable constant velocity. The ejection system includes syringes which contain the above solutions and which dispense equal volumes of each solution per unit time into a gelatin medium in the container. The container is surrounded by a water jacket maintained at a constant temperature by a heating element controlled by an adjustable thermostat.
