Abstract: A variety of etching bath-based demetallizing processes for making various products involve immersing a web of metal-containing material in a bath of aqueous etchant. The metal-containing material is protected by a pattern of etch-resistant material during the demetallizating process to form functional features having a function in the product in the metal-containing material when the web has been demetallized. The metal-containing material is also protected by a pattern of etch-resistant material over areas of the metal-containing material that serve no function in the product, but rather function in one or more ways to improve the chemical milling process, such as, for example, by extending the etchant bath life, preventing excessive heat generation in the etchant bath, maintaining the etchant bath stable and controllable, increasing web rigidity, and imparting predetermined flex characteristics to the web.

Abstract: Corruption of features formed by etching a metal-containing web in a continuous etch process is reduced by distorting the original design or designs of the features to compensate for localized areas subject to excessive etching during the continuous etch process. In the case of a planar speaker diaphragm, for example, the width of the portions of the trace that are in a cross-machine direction is increased to compensate for the higher etching rate caused by the motion through the etch bath. While this causes the modified trace design to appear to be distorted relative to the original trace design, the etched trace resulting from the modified trace design has improved uniformity and greater fidelity to the original trace design than if the original trace design had been used in the continuous etch process.

Abstract: A microwavable package includes a base to support a food product, an active microwave energy heating element is on the base to effect heating of the food product upon impingement by microwave energy. A cover spaced from and separate to the active microwave energy heating element overlies the food product.

Abstract: A simple and inexpensive container is constructed to dispense the contents of the container in predetermined, controlled amounts. Preferably, the container includes a reservoir that is adapted to hold a predetermined amount of material. The reservoir includes an opening through which the predetermined amount of material enters the reservoir. A flow tube is connected with the reservoir and communicates with a pour spout through which the material being dispensed exits the container. When the container is positioned upright, the predetermined amount of material fills the reservoir. When the container is turned upside down to dispense material from the container, only the material in the reservoir is able to flow into the flow tube and be dispensed from the container through the pour spout. The container is preferably formed from a two-dimensional blank, which is folded and secured to form the container. A method of forming the two-dimensional blank into the container is also disclosed.
