Abstract: The invention provides a method for reducing or eliminating the odors commonly produced by the sterilization of polyolefin-based products by gamma radiation. In addition, the invention also provides a method for minimizing the amount of fabric strength loss associated with the irradiation process and a method for actually increasing the fabric strength of a polyethylene that has been irradiated. Both the reduction in odors and the minimization of strength or increase in polyolefin strength are achieved in methods comprising the use of an oxygen scavenger. The invention further includes the use of non-gamma stabilized polyolefins. The polyolefinic product may also include an odor mask that may be used to mask any residual odor.

Abstract: A method and apparatus for flavoring coffee with a particular flavoring ingredient in situ within the package. The apparatus includes a hopper for containing a supply of coffee and a connected feed tube through which the coffee is delivered in measured amounts into the lower end of a tube of sheet material or web which is being continuously formed about the coffee feed tube to define the package for the coffee. A flavoring feed tube connected in communication to a reservoir containing a supply of flavoring material is disposed along the coffee feed tube and through which the flavoring material is circulated for injecting a predetermined amount of flavoring material into the coffee being delivered into the lower end of the continuously formed tube. The lower end of the continuous tube containing the predetermined amount of coffee and flavoring material is thereafter sealed and separated from the remainder of the continuous tube to define an individual package of flavored coffee, and the sequence repeated.

Abstract: A method of sterilizing medical products with an ozone-rich atmosphere is disclosed. The method avoids contamination problems that can arise under prior art ethylene oxide sterilization methods. Moderate, carefully controlled conditions are used. The method is particularly suited to the sterilization of sensitive materials such as catgut, polyglycolics and other absorbable synthetic polymeric replacements for catgut. The invention includes sterilized products produced by these methods.

Abstract: Baled animal feed material is improved by being moved onto a vehicle either by a lifting mechanism at the side of the vehicle or by a platform which takes the bale directly from a baler. On the vehicle is firstly mounted a wrapping station in the form of a cradle which rotates the bale about its axis and about an axis at right angles to the bale so that the plastic strip material is wrapped around the bale and around the ends of the bale. A probe is moved forwardly hydraulically to enter the bale along its axis following which anhydrous ammonia from a volumetric measuring device is injected under pressure from a hydraulic supply through the probe into the bale.

Abstract: Vaporizers with flat wicks folded into U-shape within open-topped, laterally apertured generally prismatic casings, capped by complementary covers which are vertically slidable thereon to control the escape of a volatile liquid impregnating the wicks, are mass-produced on a plurality of assembly lines each comprising a wick-loading station, an impregnating station, an insertion station and a capping station. The dry and unfolded wicks are successively advanced from their loading station along an upper track past the impregnating station, where they are permeated with the liquid, to the insertion station in which a plunger thrusts each wick through a narrow central slit into an aligned casing waiting on a lower track, the wick being doubled in passing through the slit into the casing.
