Abstract: An end dam for use in a coater head which applies a coating material under pressure from a reservoir onto a web is shown to include an attachment arrangement for attaching the end dam to the coater head a first wall which prevents the lateral movement of the coating material, thereby defining one end of the reservoir, a second wall, spaced from the first wall and laterally away from the reservoir, such that a channel is formed therebetween so that coating material passing over the first wall experiences a drop in pressure sufficient to maintain the coating material within the channel.

Abstract: Portable containers suitable for use as disposable contaminated material containers are provided. The containers include a top closure including first and second closure flaps whereby the first closure flap has a central opening for filling the box and a handle member for holding it. The handle member can be inserted into a corresponding aperture of the second closure flap which protects the handle from being contaminated during use. The design also includes using an interior space defined by an internal open-ended container wrapped in a preferred thermoplastic bag. This feature enables the container to resist leakage of contaminated materials and the risk of puncture of the container by sharp objects.

Abstract: A process for purifying exo-2-hydroxy-1,4-cineole contaminated with ketones is carried out by derivatizing the ketone to form a compound readily separable from the desired cineole, either by distillation, solvent extraction or like separation process. In one embodiment method of the invention, derivatization is carried out by reaction of the ketone with an amine. The amine reacts with the ketone impurities to form water and relatively stable enamine derivatives that have a much lower vapor pressure than the exo-2-hydroxy-1,4-cineole. The desired product may then be separated by distillation.

Abstract: Polyamide resins are produced by reacting diamines, polymeric fatty acids, and monoamines. The monoamine component serves as a chain stopper and renders the polyamide resin product soluble in toluene. The resulting resins are especially useful as binder components in printing inks, and are distinguished by their ready solubility in toluene alone.
