The invention provides methods and compositions related to transgenic plants which incorporate genetic traits of the marine eelgrass Zostera marina. These traits include pathogen resistance, which may be conferred by stimulating zosteric acid biosynthesis, and root anoxia resistance, which may be conferred by introducing one or more anoxia-induced or anoxia-resistance genes.

A continuously variable transmission includes at least one transmitter having two graduated surfaces mounted to provide frictional engagement with a driving cylinder and a driven cylinder. A shifter having two graduated surfaces is axially mounted within the housing. The transmitter is not mounted on a shaft, but is urged into engagement with the driving cylinder and the driven cylinder by two elongated followers. Each follower includes a first end and an opposing second end. Axial movement of the shifter provides simultaneous and opposing movement of the first and second followers to impart pivotal movement of the axis of rotation of the transmitter.

The present invention enables the formation of droplets due to capillary stream break-up and minimizes variation in droplet formation time by applying a transverse disturbance to initiate instability on the capillary stream's surface. In one embodiment, a side-shaker apparatus comprises a reservoir adapted to hold molten metal, an orifice plate having an orifice in fluid communication with the reservoir, and a transverse disturbance generating member coupled to the orifice plate. The molten metal in the reservoir is ejected from the orifice to form a capillary stream. Due to capillary stream break-up, droplets pinch off from the capillary stream to form a droplet stream. The transverse disturbance generating member vibrates the orifice plate laterally (i.e., side to side) to apply a transverse disturbance to the capillary stream.

A junction plate assembly for subsea hydraulic couplings has gear-driven cam followers on the circumference of one, generally circular, junction plate and curved cam tracks on a corresponding junction plate to urge the plates together or apart. The gears can provide significant mechanical advantage in moving the junction plates. Accordingly, larger junction plates with a greater number of hydraulic coupling members may be joined together when using the apparatus of the invention. The mechanical advantage provided by the junction plate mechanism allows the use of smaller, less powerful Remotely Operated Vehicles (ROVs) to make hydraulic connections in the subsea environment.

A control circuit (1) includes two input terminals (2, 3) for respectively electrically connecting with the active and neutral conductors (4, 5) of a mains power source (6). Two output terminals (7, 8) electrically connect with a load in the form of a two pin domestic electrical appliance (9). Conductors (4, 5) terminate at a domestic power outlet socket, and terminals (7, 8) are incorporated into a two pin plug for insertion into that socket. That is, terminals (7, 8) include elongate bundled conductors for extending between the outlet socket and the circuit. Appliance (9) has a conductive component, in this instance a housing (10) that, under normal operating conditions, is electrically insulated or otherwise electrically isolated from conductors (4, 5). The housing provides a reference point for circuit (1), and is electrically connected to that circuit by way of a conductor (11).
摘要:
A catalyst of a gallium zeolite on which platinum (Pt/Ga-ZSM-5) has been deposited may be used for aromatization of alkanes having two to six carbon atoms per molecule, such as ethane, propane, butane, etc., to aromatics, such as benzene, toluene and xylenes (BTX). The gallium zeolite contains gallium and silicon in the framework of the zeolite structure. The zeolite structure may be of MFI, FAU, TON, MFL, VPI, MEL, AEL, AFI, MWW or MOR, but preferably, the zeolite has a MFI structure, more preferably is ZSM-5 MFI zeolite. According to the IUPAC recommendations, an example of the sodium form of the zeolite would be represented as: |Nax·(H2O)z|[GaxSiyO2y+3x/2]−MFI where x=0.1-25; y=60-100; and z=0.1-10. Platinum may be deposited on the gallium zeolite by ion exchange or impregnation.
