摘要： The invention relates to a multi-layer structure in which one or more layers contain an acrylic polymer, and one or more layers contain biopolymers. The acrylic polymer and biopolymer could be in different layers of the structure, or in the same layer of the structure. The combination of acrylic polymer and biopolymer in the same multi-layer structure provides improved properties, such as improved adhesion, improved mechanical properties, and improvements in the ease of manufacturing. An inner layer containing a biopolymer gains significantly improved UV resistance, abrasion resistance, and surface appearance, when covered with an outer acrylic layer. The multi-layer structure may be in the form of a sheet, a film, a tube or pipe, or a profile, and could used by itself or as a cap-layer over another substrate.

摘要： The invention relates to a multi-layer polymer structure having a polyolefin-based layer, an acrylic-based or other polar polymer layer, and a tie-layer between and adjacent to the polyolefin and acrylic-based layers. Each layer could contain multiple sub-layers. The invention specifically relates to the composition of the tie-layer used to bond the polyolefin- and the polar polymer layers together. The multilayer structure can contain more than three layers, with polar polymer layers on each side of the polyolefin-based layer, and can be made by any method known to the art. The multilayer structure exhibits excellent structural integrity, excellent surface appearance, high impact strength, high scratch resistance, and excellent resistance to UV rays.

摘要： A control system utilizing a programmable controller for an injection molding machine in which the controller is periodically scanned in response to input signals to produce output control signals is provided with an impulse response filter arrangement. The impulse response filter senses a plurality of current and past sensor input signals to accurately predict the occurrence of a variable triggering event which will in fact be sensed by a sensor. A predictive sensor signal is then generated which is inputted to the controller in advance of the occurrence of the triggering event and at a time which corresponds to the processor scan time so that the controller generates the desired output at the precise time the triggering event occurs thus eliminating controller response latency from the control system.

摘要： An energy efficient general purpose injection molding employs a hydraulic drive for injection and clamp machine functions and an electric drive for screw recovery. Both drives use AC "squirrel cage" induction motors under vector control. Speed command signals for the vector controls are generated by the machine's controller utilizing state transition and predictive signal techniques to account for motor and motor/pump response latencies. Hydraulic drive efficiency is improved by varying motor speed/pump output to match cycle requirements to retain hydraulic drive advantages for mold clamp and injection functions while improving the electric drive performance for screw recovery.
