Patent EP-0311161-A2 (EP)
Inventor: KUDERT FREDERICK G
IPC: B32B27/28
Filed: 1984-04-11
Abstract: For co-molding a plurality of articles from a plurality of polymeric materials, a preferred molding apparatus has a plurality of valve-controlled co-injection nozzles (296) and injection cavities (102). The polymeric materials (A to E) are melted and fed from their sources (202, 204, 206) by screw extruders (214, 216, 218) to a set of rams (232, 234, 252, 260, 262) which appropriately pressurize and move streams of the polymeric materials to feed blocks (296) each associated with or forming part of a respective nozzle (296) for injection into the related cavity (102). The streams leaving the rams (232, 234, 252, 260, 262) are conveyed along respective runner ducts (220, 222, 250, 257, 258) to a runner extension member (276) in a runner block (288), and in the runner extension each material stream is divided into a plurality of branch streams. Each branch stream is ducted to flow splitters in the runner block (288) for further division into plural feed streams equal in number to the number of nozzles (296), and the separate feed streams are then fed one to each nozzle (296). The apparatus is configured such that for each material, the plural feed streams reach their respective nozzles (296) after passage along ductings of the same length and geometry to ensure that the streams enter their nozzles as nearly as possible in the same condition, ready for injection. Each nozzle (296) receives the polymeric materials (A to E) as separate feed streams and combines them appropriately into a plural-layer, plural-material stream for injection. The nozzles all have pin and sleeve valves (800, 834) to control admission and flow of the different materials to their central channels (240) wherein the combined stream is formed. Valve operation is under microprocessor control (2040) and the valves - which are effectively substantially identical - are coupled to common valve actuating cams (850, 856) for operation in   unison, so that at any instant in the molding cycle the combined streams formed in the nozzles (296) for injection are as near as possible identical to one another. By appropriately controlling the pressures of the polymeric material streams and by appropriately controlling the timing of valve operating movements, precise control is obtainable whereby e.g. internal layers of the injected articles are positioned where best suited depending on the service required of the articles. 
     The method and apparatus are applicable to the production of injection or injection blow molded articles such as containers for commestibles and beverages.

Abstract: A business form assembly (10) is provided in which the outer or top sheet (32) is formed with a substantially rectangular window (38), which must be closed at the completion of the manufacturing stage. To this end, a patch or cover sheet (52) with dimensions slightly larger than the window, is temporarily attached, by pressure sensitive adhesive, to the sheet (44) next adjacent to the top sheet but in overlying relationship with the window. The underside (40) of the top sheet is provided with a heat activated adhesive pattern (54) about the periphery of the window and facing the patch or cover. When the form is substantially complete, heat is applied to activate the various lines of adhesive utilized in the form, and including the pattern about the periphery of the window. In this manner, the patch or cover becomes permanently attached to the underside of the top sheet, and is easily removed from the adjacent sheet since the heat activated adhesive is stronger than the pressure sensitive adhesive.

Abstract: In a cylinder head for a reciprocating internal-combustion engine, with a control chamber arranged adjacently in a control housing and a guide, associated with the control chamber in the control housing, for a tappet of a spring-loaded lift-type valve of a gas exchange passage, said valve being guided in the cylinder head, the tappet guide has guide surfaces which are formed on spaced parts, interact only with parts of the circumference of the tappet, said parts lying opposite to one another, and of which at least one is provided on a wall part arranged in free-standing fashion in the control housing. To achieve structurally integrated guide surfaces without special expense in the case of a cylinder head produced by casting, it is proposed that the other guide surface of the laterally open tappet guide be provided on one of the lateral boundaries of the control housing and that the wall part having one, opposite guide surface be connected integrally to the cover wall of the cylinder head.

Abstract: Complex waveforms may be transmitted using Lincompex techniques by frequency shifting either the complex waveform, its envelope, or both, in order to ensure that the compressed complex waveform and the envelope signal are transmitted without any substantial overlap therebetween utilizing Lincompex techniques. Overlap between the compressed waveform and envelope prevents the proper demodulation of the complex waveform from the signal transmitted. Accordingly, the frequency shifting techniques utilized in the present application allow Lincompex techniques to be utilized with complex waveforms having both a large bandwidth and a large envelope bandwidth, for example, the waveforms generated by parallel tone or multi-tone digital data.

Abstract: Methods and apparatus are disclosed for realizing an integrated cache unit (ICU), that is a cache unit comprising both a cache memory and a cache controller on a single chip. The novel ICU is capable of being programmed, supports high speed data and instruction processing applications in both Reduced Instruction Set Computers (RISC) and non-RISC archi­tecture environments, and supports high speed processing applications in both single and multiprocessor systems. According to the preferred embodiment of the invention, an ICU is disclosed which includes 8k bytes of data, 512-20 bit words of tags, and the necessary control to fully implement cache functions. The preferred ICU has two buses, one for the processor interface and the other for a memory interface. The ICU supports single, burst and pipelined processor accesses and is capable of operating at frequencies in excess of 25 megahertz, achieving processor access times of two cycles for the first access in a sequence, and one cycle for burst mode or pipelined accesses. It can be used as either an instruction or data cache with flexible internal cache organization. A RISC processor and two ICUs (for instruction and data cache) implements a very high performance processor with 16 k bytes of cache. Larger caches can be designed by using additional ICUs which, according to the preferred embodi­ment of the invention, are modular. Further features include flexible and extensive multiprocessor support hardware, low power requirements, and support of a combination of bus watching, ownership schemes, software control and hardware control schemes which may be used with the novel ICU to achieve cache consistency.

Abstract: A real-time database provides the predictable, high speed data access required for on-line applications, while providing flexible searching capabilities. The data retrieval routines include the option to "read-through-lock" to access data in locked data tables, the capability to directly access to data using tuple identifiers, and the capability to directly access unformatted data from input areas which contain blocks of unformatted data. The data updating routines include an option to omit index updating when updating data and an option to update data in a locked data table. Multiple indexes can be defined for a data table. Thus, high speed searches can be performed based on a variety of data fields. The data storage and retrieval mechanisms are independent and there are hash index tables that connect the multiple index keys to the data tables. The data table structure includes a column defined for storing tuple identifier strings. These tuple identifiers can be used as pointers for chaining to related data stored in other data tables. The database has relatively small programmatic memory. There is a common structure for user data tables, index tables and system tables. The database includes a minimum number of routines with certain routines providing multiple functionality.
