Abstract: An aerated bath 26 is disclosed comprising a plurality of receptacles 10 on the outside of the bath, each receptacle being in communication with the interior of the bath through one or a plurality of openings 16, and fluid supply means 20 connected to some or all of the receptacles characterised in that the receptacles are shallow and of a relatively smooth internal configuration. Preferably, the internal configuration of the receptacles is a part spherical dish. The smooth internal surface reduces locations where moisture can be trapped. Preferably also, the receptacle is made from a material, especially a plastics material, which is hydrophobic which therefore resists wetting by bath water. The plastics material is preferably easily machinable, and tough and durable, and may be selected from known plastics materials of this type such as nylon, polyethylene terephthalate, and the like.

Abstract: Disclosed is a separator for separating a meltable solid from a mixture with other solids. The separator has a tank for holding a fluid; a container at least partially inside the tank, made at least in part of a screen through which the fluid can pass and melted solids can flow, but through which the unmelted solid material will not flow; and a heater for heating the fluid above the melting point of the meltable solids. Also disclosed is a method of separating a meltable solid from a mixture with other solids. The mixture of solids is placed in the container of the separator and the fluid is heated to a temperature above the melting point of the meltable solid, whereby the meltable solid flows through the screen out of the container, while the other solids remain within the container.

Abstract: A paper product suitable for use in making envelopes and the like and having enhanced printability. The enhancement in printability is attained through the use of shoe nip calendering. The final product has the following material properties: (1) a basis weight in the range 16-32 lb./1,300 ft2; (2) a density equal to or less than 0.75 g/cc; (3) a smoothness as measured by the Hagerty/Sheffield test (TAPPI Test Method T 538 om-88) greater than 200 Sheffield units; and (4) a Parker Print Surf roughness as measured by the Parker test (TAPPI Test Method T 555 om-94) less than 5.0 microns (measured using a pressure of 10 kgf/cm2 with a soft backing).
