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 container for commestibles and beverages.

Abstract: The apparatus according to the present invention provides an alignment mask disposed in the CRT plane, and the CRT parameters are measured by observation of the light collected through the alignment mask from the CRT and processing the corresponding light intensity signals. The light sensing device provides a signal which is processed typically by a microprocessor controlled geometry engine to derive a set of correction data which is based on a prototype array of initialized data values. The parameters corrected by the apparatus and method according to the present invention include x and y position, focus and relative picture   intensity over the surface of the screen (vignette). The above listed parameters are used alone and in combination to provide image centering, image scaling and pincushion correction, correction for non-orthogonality between the x and y deflection coils, image rotation and correction for nonlinear second and third order effects. The set of data can also be deliberately distorted to provide image precompensation such as keystone (trapezoid) and spherical corrections as well as vignette compensation such that, when the final image is projected or displayed, a true (nondistorted) image results.

Abstract: Basic nitrogen compounds (BNC) are selec­tively removed from solvent extracted oils by adsorp­tion of said BNC's by solid acidic polar adsorbents. The oils are extracted using any of the common extrac­tion solvents, such as furfural, phenol, SO₂, N-­methyl-2-pyrrolidone (NMP), preferably NMP. The resulting raffinate, which contains the desirable oil fraction, has the BNC's present therein removed by adsorption thereof onto an adsorbent, characterized as being a solid, polar acidic adsorbent, exemplified by silica-alumina, a high alumina base amorphous cracking catalyst (such as manufactured by Ketjen/Akzo) and crystalline zeolite (such as H-Y zeolites) are effec­tive adsorbents. The adsorbents may additionally con­tain fluorine or may contain up to 30 weight percent water. The adsorbents are regenerated by either purg­ing with hydrogen at elevated temperature and pressure, or by washing the BNC saturated adsorbent with extrac­tion process extraction solvent, such as NMP. 
     Extracted oil raffinate treated with the adsorbent to remove BNC exhibit superior uninhibited oxidation stability as compared to untreated conven­tional hydrofined oil.

Abstract: A microwave power combining FET amplifier includes T-type branch circuits (13,14) for power splitting and for power combining, and interstage matching circuits (6a,6b) respectively corresponding to a plurality of multistage FET amplifiers (3a,3b,4a,4b). Predetermined positions (a,b) opposing to each other respectively at the interstage matching circuits are connected by a resistance circuit (15) having a predetermined resistance value. Accordingly, it is possible, without including a power splitting circuit and a power combining circuit using a branch-line type coupler or Wilkinson type coupler, to perform the equivalent function to the amplfiers employing the power splitting and power combining circuits using these types of couplers. The arrangement is simplified and the shape is made small in size, and it is particularly suitable when the invention is to be realised by using a monolithic integrated circuit.

Abstract: In a charge amplifier circuit comprising an operational amplifier stage (1), the signal output (2) of which is fed back to the signal input (4) via a capacitor feedback section (3), the signal output (2) of the operational amplifier stage (1) is also connected to the input of a subsequent further transmission stage (6) which, at least in the vicinity of the knee frequency determined by the feedback section (3) of the operational amplifier stage (1) exhibits a proportional-integrating transfer characteristic having a knee frequency which is at least approximately equal to the knee frequency of the operational amplifier stage (1). This makes it possible to optimise separately the feedback section (3) of the operational amplifier stage (1) or, respectively, the feedback capacitor (3) and the associated parallel resistor (R) independently of the respective operating frequency range, which, for example, also allows a small value for R, which is very advantageous particularly with respect to the circuit configuration, in spite of the small capacitor value which increases the charging sensitivity, the transfer characteristic remaining linear.
