Abstract: Bei einem Verfahren zur Regelung des Kraftstoff-Luft-Verhältnisses einer Brennkraftmaschine, wobei die Ausgangsspannung einer Sauerstoffmeßsonde, die im Abgaskanal der Brennkraftmaschine angeordnet ist, einem Regler zugeführt wird und der Regler eine Stellgröße für das Kraftsoff-Luft-Verhältnis abgibt, werden dem Regler ferner der Last und der Drehzahl der Brennkraftmaschine entsprechende Signale zuge- führt. Jeweils nach einem Sprung der Ausgangsspan- nung der Sauerstoffmeßsonde erfolgen ein erster Sprung und danach jeweils nacheinander weitere Sprünge der Stellgröße. Die Richtung der Sprünge hängt von der Richtung des Sprunges der Ausgangsspannung der Sauerstoffmeßsonde ab, während die Amplitude der weiteren Sprünge von der Last und der Drehzahl abhän- gig ist. Zwischen den Sprüngen weist die Stellgröße einen im wesentlichen zeitlinearen Verlauf auf, wobei die Steigung vorgegeben ist und die Richtung der Richtung der Sprünge entspricht.

Abstract: A crosslinked polymer liquid crystal is stretched to provide a polymer liquid crystal layer (5) with a higher degree of uniform alignment than a non-crosslinked polymer liquid crystal. Such a stretched layer of crosslinked polymer liquid crystal (5) is disposed between a pair of substrates (4,12) to form a liquid crystal device showing a better contrast as a recording medium or display device. The improvement in alignment obtained by stretching of a crosslinked polymer liquid crystal is also effective in increasing the responsive characteristics in response to an electric field or magnetic field and also the pyro­electric effect of the resultant polymer liquid crystal layer where the polymer liquid crystal is a ferro­electric one.

Abstract: A siren detector for detecting siren sounds which precess at known yelp, wail and high-low warble rates within a selected frequency band. A transducer (8) detects siren sounds and produces a corresponding elec­trical output signal. The output signal is filtered (10) to reject signal frequencies outside the selected frequency band. The signal amplitude is monitored and varied as required to produce a constant amplitude output signal. The constant amplitude output signal is low pass fil­tered (15) for detection of siren high-low sounds and is also low pass filtered (16) for detection and output of precession signals which pass through a selected centre frequency. Subsequent filters (19,20,21) are provided for detecting signals which vary at the wail and yelp warble rates. Wail, high-low and yelp warble rate signals output by the var­ious filters respectively trigger don't walk and yelp clock generators (23,24) which in turn drive don't walk and red light output flip-flops (26,27) respectively. Operation of the red light output flip-flop is controlled by a delay mechanism (25) which provides a further filtration level to present false triggering.

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.
