IPC: B65D71/50
Filed: 2021-02-10
Abstract: A secure container cover for a container and manufacturing method therefore are provided. The secure container cover includes an integrally molded body with an annular structure and a side wall. The annular structure includes a central void defined by an intermediate perimeter, and a graspable loop integrally formed with the annular structure is configured to reside within the central void. A tear initiation point is formed where the graspable loop joins the annular structure. A thin section extends from the tear initiation point to a bottom edge of the side wall. The graspable loop is detachably connected to the annular structure at a bridging section. The bridging section is configured to break when an upward biasing force is applied to the graspable loop, and the side wall is configured to separate along the thin section when the graspable loop is pulled away from the body of the secure container cover.

Abstract: Spannungs-Ladungswandler unter Verwendung einer Kondensatorschaltung zur Erzeugung ganzer Ladungspakete oder von Teilladungspaketen an ausgewählten, voneinander auf Abstand liegenden Stellen in einem Halbleitersubstrat. Jede Leitung eines an gegenüberliegenden Seiten der Kondensatorschaltung (C; CL, CR, CP) angeschlossenen Leitungspaares (L, R) wird durch eine eines Paares von Ladungs-Übertragungsvorrichtungen selektiv auf eine vorbestimmte Spannung aufgeladen, wobei die Ladungs-Übertragungsvorrichtung mit dem Eingang eines ersten und eines zweiten die Ladung verwertenden CCD-Speichersystems verbunden sind. Außerdem werden dabei Spannungen eines ersten und eines zweiten Pegels an jede Leitung es Leitungspaares angelegt. Durch vorherige Aufladung der einen Leitung des Leitungspaares und durch Andern der an der anderen Leitung des Leitungspaares liegenden Spannung von einem ersten Wert nach einem zweiten Wert wird ein erstes Ladungspaket in einer Potentialmulde (27) eines ersten, die Ladung ausnutzenden CCD-Speichersystems gebildet. Zum Injizieren eines Duplikats des ersten Ladungspaketes in eine Potentialmulde (29) des zweiten Systems werden gleichartige Spannungen über der Kondensatorschaltung (C) in bezug auf das zweite System angelegt. Soll dagegen in das zweite System ein Ladungspaket injiziert werden, das nur einen Bruchteil des ersten Ladungspakets darstellt, dann unterscheiden sich die gleichartigen Spannungen nr insofern, daß die Spannungsdifferenze zwischen der ersten und der zweiten Amplitude in einen Bruchteil geändert wird, die dem Bruchteil des gewünschten Ladungspaketes entspricht. Durch Voraufladung der an die Kondensatorschaltung angeschlossenen Leitungen (L, R) werden während der Ladungs-injektion parasitäre Wirkungen unwirksam gemacht.

Abstract: A complex of polyriboinosinic-polyribocytidylic acid (poly I:C) with poly-L-lysine hydrobromide ([Iysine.HBr] n ) having a defined molecular weight is prepared which is about 5-15 times as resistant to hydrolysis by pancreatic ribonuclease as the parent poly I:C. A pharmaceutical solution, containing a relatively high concentration of the complex, prepared as described, induces significant antiviral levels of serum interferon in monkeys under conditions in which poly I:C itself induces little or no interferon. An important feature of this invention is that the product is a soluble material requiring no special solubilizing agent, thereby facilitating the preparation of solutions having the desired concentration. The product will hereinafter be designated as poly I:C/poly-L-lysine.

Abstract: A convergence measuring apparatus for e.g., a color television kinescope (19) and deflection yoke (20) comprises means (23, 45, 46) for activating two of the electron beams of the kinescope to generate a convergence test pattern on the kinescope display screen. The convergence test pattern is a set of alternating color patches (11, 12, 13). The degree of overlap (15) and gap (16) between patches is indicative of the degree of beam misconvergence. A monochrome television camera (21) observes the test pattern and provides a signal to a signal processor (22) which controls the electron beam activating means to move one color patch with respect to the other color to reduce the gap (16) and overlap (15) between patches. A measurement of the amount of patch movement necessary to minimize the overlap and gap between patches is an indication of electron beam misconvergence in the vicinity of the test pattern.

Abstract: A metering tube (50) injects liquid herbicide into the central flow passage (48) of a fluid permeable rope (14). The liquid herbicide flows along the length of the rope and is emitted from the inside of the rope to its outside surface. The metering tube (50) is supplied from an accumulator tank (62) in which a volume of the liquid herbicide is pressured by compressed air. The liquid herbicide (64) in the accumulator tank (62) is maintained at a selected pressure by a charge of compressed air delivered from a storage tank (20) through a pressure regulator valve (80) to the accumulator tank. The metering tube (50) is lodged within the central flow passage (48) of the rope applicator (14) and a ferrule fastener (54) compressively engages the rope section surrounding the metering tube (50), thereby defining an annular seal which allows the flow of liquid herbicide through the metering tube (50) while preventing the flow of liquid herbicide by wicking action through the end of the rope. This arrangement provides close control of the flow rate of liquid herbicide into the rope applicator (14), and is not dependent upon the variables associated with wicking flow.

Abstract: Bei Brillenlinsen, die in mindestens einem Schnitt eine Mittendicke größer als die Randdicke und in unterschiedlichen Schnitten unterschiedliche dioptrische Wirkungen haben, führen rohrunde Formen zu eingeschliffenen Brillenlinsen, die ein relativ hohes Gewicht haben. Das Gewicht einer solchen Brillenlinse und damit ihre Mitten- und Randdicke wird reduziert, wenn die Rohform eine im wesentlichen ellipsenförmige Randkurve erhält. Zur Reduzierung von Aufwand und Kosten wird der dioptrische Bereich der Brillenlinsen-Serie in eine vorgegebene Anzahl von Bereichen unterteilt und jedem Bereich wird ein bestimmter Randkurventyp zugeordnet. In jedem Bereich gibt es zum Randkurventyp eine Anzahl von zentrisch ähnlichen Randkurven unterschiedlicher Höhe und Breite. Alle Randkurven sind so gewählt, daß die mit ihnen versehenen Roh-Brillenlinsen über ihren ellipsenförmigen Umfangsteil eine Randdicke haben, die um weniger als 1,5 mm schwankt. Es sind einfach zu handhabende Mittel zur Auswahl der optimalen Rohform vorgesehen.

Abstract: A protective arrangement for an optical fiber coupler (2) includes a substantially cross-sectionally V-shaped support element (11) which bounds an open channel (12) that receives a portion of the optical fiber coupler (2). The portion received in the open channel includes jacketed regions, continuing into bare regions (22) and a coupling region (23). Respective adhesive bodies (13) secure the jacketed regions of the optical fiber coupler (2) in the open channel (12) of the V-shaped support element (11). A strip-shaped support element (14) is connected by respective additional bodies (15) of adhesive to the bare regions of the fiber just outside the coupling region. The support elements (11, 14) are of a material having a coefficient of thermal expansion approximating that of the material of the optical fiber coupler (2). A shrunk tubular shielding element (16) tightly surrounds the V-shaped support element (11) over most of its length and its open ends are closed by respective seals (18). Shrunk tubular bend limiters (17) surround the jacketed regions of the optical fiber coupler and pass through the respective seals (18). This sub-package (1) is so inserted into a receiving channel (31) of a housing member (3) that the open side of the open channel of the V-shaped support element (11) faces the bottom surface of the receiving channel (31). A body of encapsulating material (4) embeds the subpackage (1) and holds the same in position within the receiving channel (31).
