Patent CA-2147308-A1 (CA)
Inventor: ECKARDT HELMUT
IPC: B29C45/14
Filed: 1995-04-19
Abstract: The present invention relates to a process for the injection molding of objects consisting of at least two different layers. The outer layer here consists of enamel. According to the process, a liquid enamel is used. This enamel is injected by an enamel-injection apparatus (1) through an enamel-injection die (2). The plastic melt passes through an injection unit into the cavity (3). According to the invention, the liquid enamel is injected into the flow path of the melt in the region before the cavity, before the melt is injected, so that the melt is encased by enamel before it is distributed in the cavity (3). It is thus possible to use liquid enamels to enamel injection molded parts in the tool. Furthermore, the inventive process makes possible a rapid and therefore economical mode of operation.

Filed: 1993-10-18
Abstract: A vortex flow transmitter (10) has a filtering circuit (20) receiving a noise contaminated input signal representative of the flow and which has a fundamental frequency varying responsively to flow. The filter (20) filters the input signal using one of a family of HP filter characteristics.  Each member of the family of HP filters has varying corner frequencies, each filter having a unique switchup and a unique switchdown value assigned to it. Adaptive response means (40) select a current HP filter for use in the filter means.
