摘要:
A shower system (12) for a screening machine (10) or unit and method of using the shower system (12) to clean the screen surface (24). The shower system includes a spray nozzle (28) connected to a movement arm (32), a driver (38) for longitudinally moving the movement arm (32) in a reciprocal path, and an indexing system (36) adapted to allow limited axial rotation of the movement arm (32) at predetermined longitudinal positions of the movement arm (32).

Gefäßmündungen (1) werden zur Verbesserung des Ausgießverhaltens mit einer Silanbeschichtung versehen. Hierzu dient eine Vorrichtung, die an einem drehbaren Düsenträger (14) mehrere tangential auf den Rand (1a) der Gefäßmündung (1) gerichtete Sprühdüsen (16) und Blasdüsen (17) aufweist. Ein feststehender Düsendorn (12) bildet mit seinem unteren Zentrierabschnitt (13) eine Zentrierung für die Gefäßmündung (1). Aus dem Zentrierabschnitt (13) tritt aus nach rückwärts gerichteten Luftdüsen (20) eine Luftströmung aus, die das Eindringen von Sprühmaterial in die Gefäß (2) verhindert. Aus einer die Gefäßmündung (1) umgebenden Absaugglocke (21) werden die auftretenden Sprühreste und Lösungsmitteldämpfe abgesaugt.
摘要:
A method and apparatus for removing substances adhering to a surface such as a wall of buildings in which a nozzle head having a plurality of nozzles is rotated eccentrically and moved sidewardly when used. The diameter of each of the nozzles is selected so as to be within a range of 0.05 to 0.5 mm, the pressure to be supplied to the nozzles is 800 kg/cm 2 or more, the total amount of water jetted from each of the nozzles in 12 I/min or less and the number of revolutions of the nozzle head is 800 to 4000 rpm.

Is intended to be installed in a horizontal platform in the form of a working table of a revarnishing machine to repair lids. It is characterized in that it comprises a copying device (1) sustained by a cam support (5), joined in turn to an upper support (4), the copying device having a copying cam body (3) solidary to the cam support (5), the static solidary set of these three elements (3-4-5) being coupled around the main rotary shaft (10), to which lower extremity a drum (18) is affixed dragging the copying device with its rotary movement. Said copying device has, among its elements, roller followers (25) driven in grooves (3') located in the copying cam body 3, the copying device (1) also having varnishing guns (17).
摘要:
A movable rack assembly for a washer having a generally rectangular frame. The frame includes a central hub connectable to a fluid source. A plurality of elongated tubular base members extends from the central hub and defines a bottom of the frame. A pair of spaced-apart elongated, tubular side members defines side portions of the frame and a space therebetween. Each of a plurality of spaced-apart transverse members has ends that are connected to one of the side members. The transverse members transverse the space defined between the side members. A rotary spray arm is attached to each of the transverse members. A plurality of corner spray nozzles on the frame directs fluid toward corners of the frame. The bottom members, the side members and the transverse members are fluidly connected with each other and fluidly connect the rotary spray arms and the corner spray nozzles with the central hub.
摘要:
An applicator machine 100 and a process for heating and coating a section of pipeline. The applicator machine comprises a frame 124 configured to rotate about a section of pipeline to be heated and coated, rotating means 122 operable to rotate the frame, and coating material applicators 146, 148, induction coils 138, 142 and radiant heaters 134a, 136a mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator is arranged to spray coating material through an aperture 140a, 140b through a respective induction coil. The applicator comprises an enclosure 102 configured to surround a section of pipeline and means 111, 112 for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, optionally fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.
摘要:
The invention relates to a device for dispensing one or more cryogenic fluid jets (5) at cryogenic temperature and at high pressure, comprising a nozzle-holding tool (4) including one or more fluid-dispensing nozzles, and a system (2) for causing the movement of said nozzle-holding tool (4). According to the invention, the device further includes at least one flexible protection casing (7) arranged around all or part of the system (2) for causing the movement of said nozzle-holding tool (4).
