Abstract: A security paper is provided in which identifying material is contained as an intercalary layer within the thickness of a bonded, nonwoven, polyethylene-film-fibril sheet having an opacity of at least 70% and a delamination resistance of at least 60 grams per centimeter. A process for making such paper includes forming an assembly of two unbonded, lightly consolidated, nonwoven, polyethylene film-fibril sheets containing identifying material between them, compressing the assembly in an unheated nip at 17 to 85 kilograms per centimeter of assembly width and then self-bonding the compressed assembly while under restraint by contact with a heated drum. Such security paper is useful for bank notes, stock certificates, paper currency and the like.

Abstract: To convert a sample of an amplitude-modulated voltage wave into binary pulses, the sample is simultaneously compared in two coders with two sets of threshold voltages of positive and negative polarity, respectively. Either one of the two coders yields in unbroken succession of pulses, having the same polarity as the sample, whereas the other coder produces a combination of both positive and negative pulses. Following inversion of the pulses issuing from one coder, and upon suppression of the pulses of one polarity (e.g. negative), the two pulse trains are combined into a series of bit groups each representing the absolute amplitude value of a respective sample. The final step in the processing of any sample is the generation of a sign bit in accordance with the polarity of the unipolar pulse train emitted by one of the coders; this sign bit is then transposed to the beginning of the corresponding group of amplitude bits.

Abstract: Fructose productivity and isomerase activity in immobilized beds or column operations employing isomerases obtained from Bacillus organisms are significantly improved by isomerizing a high solids feed syrup at pH 7.0-7.5 and 55.degree. C. to 60.degree. C. Without adding cobalt to the feed streams, continuous column operation in excess of 4,000 hours and yielding greater than 3,500 pounds of a 42% fructose syrup for each pound of isomerase can be achieved.

Abstract: A process and apparatus for packaging products such as dusty powders are provided. The apparatus is an enclosed housing (e.g., a glove box) with an open lower end and having two glove openings with gloves attached, an opening for attaching a waste disposal bag thereto, and an optional opening for attaching a bag for product samples. The glove box has means for securing a bag in a filling position around the lower end and has the discharge end of a product fill pipe extending into the open lower end. There are vacuum means for applying a vacuum to the inside of the glove box and for applying a vacuum from the inside through apertures circumferentially arranged around the lower edge of the glove box. The described process involves attaching a bag, e.g., polyethylene bag, around the open lower end of an enclosed filling chamber (e.g.
