A hard tonneau cover having one or more sections is constructed of a framework of extruded rails with one or more section panels held by molded plastic trim strips installed on perimeter rails included in the framework. The cover is mounted above the cargo box of a pick-up truck by a plurality of striker-latch assemblies on one side of the cargo box, and hinge assemblies on the other side, each having components mounted to the cargo box side walls with universal clamp brackets. The panels are constructed of reinforced corrugated plastic which is covered by a color integrated film. A simplified connector plate is used to connect abutting ends of the rails in the framework. A peripheral seal extends down from the perimeter rails in which it is mounted to engage the top of the cargo box side walls and tailgate. Water drainage paths including drainage channels in the rails are provided to eliminate water from the panel surfaces.

A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve. The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve. The jet valve can prevent fluid loss to the formation when being set down whether the crossover tool is supported on the packer or on the smart collet.

A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or multi-acting circulation valve allows switching between the squeeze and circulation positions without risk of closing the low bottom hole pressure ball valve. The low bottom hole pressure ball valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the low bottom hole pressure ball valve. The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.

A multi-fold leaf (30,31) joinery assembly has a joinery bogey unit (2) that is pivotally connected to a joinery leaf. A seal (20) is provided on a moveable edge of the leaf adjacent to the bogey unit, the seal being adjacent to a frame seal (25) for a head or sill of a frame of the assembly when the at least one leaf is in a closed position. The pivot connection is off-set so that the seal moves away from the frame seal when the leaf is opened, thus avoiding scrubbing.

The invention relates to a flat-panel television protection screen, which comprises a transparent panel, a shading rim which is arranged on the peripheral edge of the transparent panel and a buffering layer which is adhered onto the shading rim, wherein at least one heat radiation device is arranged on the position corresponding to a flat-panel television frame, and the flat-panel television protection screen is characterized in that the heat radiation device comprises a first main contact surface which is contacted with the outer surface of the flat-panel television frame, a second main contact surface which is contacted with the inner surface of the shading frame and one or more heat radiation passages which extends in the length direction of the first main contact surface and the second main contact surface, wherein the first main contact surface is parallel to the second main contact surface, at least one of the two end surfaces formed by an port of one or more heat radiation passages is provided with a ventilation film. The flat-panel television protection screen is used for protecting a flat-panel television display device, simultaneously the heat radiation problem of the protection screen is also solved, and the influence of small particles such as dust, fogdrop and the like on the flat-panel television display device can be effectively avoided.

The invention discloses an intelligent resin scrubbing endpoint detection device and a method thereof. A special sampling tube is connected to a water discharge main tube in the middle of a resin separation tower, an anion-exchange tower and a cation-exchange tower in the fine treatment in-vitro regeneration system of a power plant, the resin scrubbing endpoint detection device is mounted on the sampling tube, and an electromagnetic valve interlocked with the program control system of the power plant is arranged to control when the detection device is put into use. The resin scrubbing endpointdetection device online detects the quantity of particles in a scrubbing waste liquid, and transmits the switching information of the electromagnetic valve and the detection result of the quantity ofthe particles in the scrubbing waste liquid into the program control system of the power plant; a device performing resin scrubbing is determined through combining opening and closing conditions of an air inlet valve and a middle water discharge valve, and the endpoint of the resin scrubbing of the tower is determined by detecting the quantity of particles in the scrubbing waste liquid in order to determine the frequency required by tower resin scrubbing; and the device and the method have the advantages of energy saving, emission reduction, reduction of the water consumption in resin regeneration, prolongation of the periodic water production amount of a fine treatment mixed bed, and prolongation of the service life of the resin.

The invention relates to the field of color concentrate processing, in particular to plastic color concentrates and an intelligent preparation system and method of the plastic color concentrates. Theprocessing method includes the steps that liquid pigments, liquid dispersing auxiliaries and liquid resin are sequentially added into different stirring intervals of two gathering processing cylindersaccording to raw materials with different colors, and a driving machine frame is electrified to drive four mixing stirrers for mixing stirring; after even stirring, driving is stopped, specified mixed liquid is guided into different extrusion forming intervals of the two gathering processing cylinders through four manually-operated guide valves, the four manually-operated guide valves are closed,the driving machine frame is powered on to drive four combined forming extruders to continuously extrude mixed raw materials in two condensation water tanks; after multiple extrusion, the color concentrates after extrusion condensation forming are intermittently discharged through the driving machine frame; the color concentrates with different colors can be processed and formed at the same time;the materials include the pigments, the resin and polyethylene low molecule wax.
