Title: Sequential fill valve gated injection molding system
Inventor: BETTERS JAMES E
IPC: B29C45/00
Filed: 1998-06-09
Granted: 2007-10-02
Abstract: A system for injection molding of large components is disclosed that provides for the production of higher quality large molded components with a reduction in both molding cycle time and molding costs. Plasticized material communicates with a mold, having at least one single cavity, through a manifold that has at least two spaced valve gates that are independently opened and closed as directed by a controller to selectively communicate plasticized material to the mold cavity at separate locations in the mold cavity. The controller directs the valve gates to sequentially open and close during the filling phase so as to achieve the desired melt front advancement within the mold cavity. Once the mold cavity has been filled as desired, the valve gates are closed to effectively seal the manifold from the mold cavity. The plasticized material within the manifold is held in compression while the mold cavity is open, so as to prevent appreciable expansion of the material that has been found to result in molded part imperfections. Additional material may be plasticized and held in compression while the mold cavity is open, resulting in a further reduction in overall cycle time.

Title: Agrafe microfil destinee a maintenir en place le composant resistif d'un element chauffant
Inventor: GRIFFITHS SIMON P
IPC: H05B3/74
Filed: 1998-10-13
Granted: 2002-02-26
Abstract: L'unité chauffante (H) de la partie supérieure d'un cuiseur comporte un élément chauffant (E) du type ruban. Cet élément est mis en place sur la face supérieure d'un aggloméré (I) de matériau isolant microporeux. Il est disposé sur le matériau selon une configuration prédéfinie et plusieurs agrafes (10) sont utilisées pour l'assujettir audit matériau et l'y maintenir en place. Ces agrafes, du type microfil, sont séparées les unes des autres et placées sur la longueur de l'élément chauffant, ce qui permet de monter ce dernier sur l'isolant. La masse thermique de ces agrafes microfils est réduite, ce qui évite la formation de puits de chaleur aux endroits où elles sont installées et, partant, ne compromet pas l'efficacité du transfert de chaleur entre l'élément chauffant et le produit chauffé. Ces agrafes sont faites, de préférence, du même alliage métallique que celui qui a été utilisé pour l'élément chauffant et résistent à des températures élevées ainsi qu'à de nombreux cycles thermiques, ce qui permet d'allonger la durée utile de l'ensemble.

Abstract: The process and apparatus of the present invention limits the output power of a radiotelephone, operating in a cellular system in the preferred embodiment. This ensures the transmitted sidebands and synthesizer phase noise remains within a certain specification. This is accomplished by power detection and a correction accumulator that together, generate a gain control signal by limiting the gain adjustment to a maximum value, even when the cell site communicating with the radiotelephone is sending power turn-up commands to the radiotelephone. This process includes dynamically correcting the output level of the transmitter due to gain variations in the transmitter stages or gain control elements.
