A traveling water screen comprising an endless foraminous belt with flights. The foraminous belt forms a water screen extending from a lower end in a flowing stream to an upper end above the surface of the stream. The stream flows through openings in the foraminous screen. The flights, which may be scoops, are arranged in spaced apart relation on the outer surface of the water screen. The water screen is driven in a direction so that its upstream portion advances upward and its downstream portio...

A transmission screen is capable of preventing the reduction of contrast in images due to external light such as emitted by internal lighting fixtures. The transmission screen includes a Fresnel lens sheet having a front surface facing the viewer and provided with Fresnel lens elements, and a shading sheet 13 placed contiguously with the front surface of the Fresnel lens sheet. The shading sheet 13 is provided with shading elements 22 for absorbing external light fallen on the front surface of t...

A shower screen includes an upper guide rod secured on top of two posts, a screen member having a number of panels foldably coupled together and having an upper portion slidably attached to the guide rod, and two beams secured to sides of the screen member. A lower guide bar is secured to lower portions of the posts, and includes a downwardly facing passage. The beams and the screen member each includes a hook member or hook device having a projection slidably engaged into the passage of the gui...

A system that allows connection of extension panels to a main output panel. The extension panels are attachable and removable from the main output panel. The extension panels receive power and/or data from electrical connectors on the main output panel, and function to extend the data display capability of the main output panel, and may be used autonomously with stored data and/or its own CPU.

In a screen printer for printing paste to the substrate through a pattern hole by abutting a mask plate on the substrate, the end face of a side end portion of the substrate is nipped and held from its both sides by a clamper. A warp correcting portion mounting a warp-correcting member constructed by a plate-shaped resilient metal is arranged in the clamper. When the substrate held to a substrate holding portion of a Z-axis table is clamped, a free end portion of the warp correcting member is ab...

A projection screen has first transparent particles tinted a first color and second transparent particles tinted a second color.

A wellbore screen includes a base pipe including a wall, an inner bore surface and an outer surface, an opening formed through the base pipe wall and a filter cartridge mounted in the opening. In one aspect, the wellbore screen includes an impermeable layer relative to the opening and the impermeable layer may be selected to be substantially impermeable when in a closed position in the opening to passage of fluids through the opening and, the impermeable layer is at least one of (i) selectively ...

A fireplace screen arrangement is disclosed which includes a frame upon which a pair of mesh screen doors are pivotally mounted for movement between closed and open positions with respect to the fireplace. A damper assembly is provided for regulating the amount of air which is admitted to the fireplace through the screen arrangement. In order to provide convenient opening of the screen doors, a door-opening mechanism is provided which includes a door-engaging lever fulcrummed for pivoting moveme...

A screen machine, particularly for cellulose pulp and recycled pulp, which includes a screen rotor (15), which is rotatable in a housing (16) having an inlet (17) for pulp suspension, an outlet (18) for accepts and a discharge opening (19) for rejects. The screen rotor (15) is so arranged between the inlet (17) and the outlet (18) that flow therethrough from its inlet side has a radially inward directed component. On the outlet side of the rotor (15) is arranged at least one stationary baffle me...

A screening basket has one or more screen decks and has upright side walls integrated with cross beams. A side beam, at approximately the center of gravity of the basket, is integrated with each of the side walls as well as with the cross beams to provide a unitary, rugged basket capable of vibratory movement on a support frame. A pair of cross shafts extend transversely of the screening basket and project beyond the side walls. These shafts are journaled in the side beams and have one projectin...
