Compounds of the general formula ##STR1## where R.sup.2 and R.sup.3 together, or R.sup.3 and R.sup.4 together, represent an optionally substituted hydrocarbyloxy chain; the ring is optionally substituted at any or each of the remaining sites R.sup.5, R.sup.6 and R.sup.2 or R.sup.4 : n represents 0 or 1; and X represents a cyano group, a group --COOH or a salt, ester or amido derivative thereof; are biocidal, showing activity against fungi, yeast, bacteria and nematodes. Some such compounds, and intermediates therefore, are novel.

A pinch bar for a pinch valve is comprised of a coil spring coupled to one end of an actuating rod. An opposite end of the rod is formed with, or is coupled to a device or surface, which applies a pinch force. The actuating rod slides through a fixed-in-place rod actuator. The rod actuator, spring and actuating rod thus provide a mechanism that applies a closing force inwardly, into or directed toward a cabinet attached to which is a valve body for the pinch bar and against which the pinch bar could exert a tube-closing force.

The invention disclosed is directed to a method and apparatus which allows a “rolling shutter” type of read out sequence in a pixel array that is read using a double sampling technique by having the rows of pixels reset a second time in each of their cycles for a second sampling while the rows are being accessed for reading. In this way, each pixel is sampled to compare its voltage level after integration to its voltage level as it is reset. In accordance with the present invention, the row access signal or a signal that is used to generate the row access signal, is used to generate a second reset signal at the correct time while the row is being accessed. The invention is particularly applicable to image sensors having light sensitive elements that are CMOS pixels, and in particular three transistor pixels.

Lower spiked rollers in the bottom of a cotton accumulator are inclined in the downstream direction towards an opening and rotate in the same direction to pull cotton down to the opening. An upper spiked roller located above the opening and above the last of the lower spiked rollers is only partially exposed to the cotton in the accumulator. The upper roller meters the cotton and tears apart clumps. An opening above the upper roller defines an upper discharge opening over the main discharge opening. When in a non-rotating condition, the spiked rollers act as a floor for the accumulator and prevent egress of the cotton through the openings.

摘要:
A chassis-mounted round baler particularly useful with an on-board cotton module building system includes a bale release gate frame section connected to a forward frame section by a four bar linkage to define a gate path that allows the folding of the baler into both field transport and shipping configurations while maintaining desirable operating, transport and shipping heights. The gate linkage incorporates a self latching feature wherein a small vertical movement of the gate as the gate cylinders are operated releases a gate latch member from a forward frame member during gate opening and reengages the gate latch with the forward frame member during closing. The gate interacts with the bale handler to provide a stop for the baler gate when the baler gate is placed into a cradle on the handler.
摘要:
A method and system for delivering and managing assessments involving using an interface device, connected to an electronic and/or communications channel(s), to access an assessment delivery and management system in order to provide access to certain information content and to provide access to assessment items. User activity within an interface device occurs within an environment in which multiple components are present in a manner that produces a continuous unified perceptual experience. Thus users can create and modify assessment results while in the presence of the information content, which most likely represents, either directly or indirectly, the material or subject for which an assessment is being created. User activities within one component do not material affect or disturb information in other components unless the user intentionally chooses to alter other components. Modifications to the assessment results may also occur within the continuous unified perceptual experience.
