Abstract:
A degreasing apparatus for an elongated member including a treatment room sequentially divided in an isolated fashion and along the feeding direction of the elongated member into a degreasing chamber, a predrying chamber and a finish drying chamber. At least one pair of rotary brushes are provided in the degreasing chamber. The degreasing chamber is also provided with means for jetting out a degreasing liquid in a direction toward the inlet side of a contact area between the brushes and elongated mechanism. Elastic degreasing members are provided, respectively, at the inlet and outlet sides of the degreasing chamber to remove oil or grease from the elongated member before it enters the degreasing chamber and to wipe off any degreasing liquid remaining on the elongated member prior to passing the same into the predrying chamber. The predrying chamber houses a mechanism for jetting out water or steam against the elongated member while the finish drying chamber is provided with a mechanism to blow hot air against the elongated material and to dry it completely. The above degreasing apparatus can be formed in a reduced size and convenient for coupling with drawing machine and/or roller straightening machine, thus enabling continuous treatment of elongated members. Owing to the mutual isolation of the chambers, their respective treatment media can be saved and the overall processing efficiency can be improved.
Abstract:
A liquid weed killer dispenser is disclosed. The dispenser is adapted to be mounted on and disposed about a pole such as a telephone or telegraph pole. The dispenser includes a box-like holder for water and a weed killer which is dispersible in the water. The holder has a recessed top which defines a rain water receiving perforated tray through which the rain water can flow into the holder. The top is readily removable from the holder. Weed killer containers, such as bags, are disposed in the holder. The containers are connected to the top so as to be removable with it from the holder and readily replaceable. The dispenser also includes a liquid distributor which includes a pair of tubes. Each of the tubes has a first substantially semi-circular part adapted to surround one half of the pole and a second substantially vertical part which is directly connected to the first part and which is in fluid communication with the holder through the bottom of it to receive the weed killer dispersed in the water from the holder. Each of the tubes may be pivoted relative to the holder through the second part thereof so as to be openable and closable for mounting and dismounting the dispenser on the pole. A spring is disposed between the tubes so as to bias them toward each other and thereby normally close them about the pole. The first part of each of the tubes has a plurality of spaced radially outwardly extending holes therein through which the weed killer dispensed in the water may flow downwardly along the pole to kill any weeds thereon.
Abstract:
While a rectangular sheet is being passed between a masking packing having at least one opening of a configuration corresponding to the selected area of the sheet to be plated and a pressure packing, a jet of plating solution is continuously directed from a nozzle against the masking packing opening or a jet of plating solution is intermittently directed from a specially designed nozzle against the opening in response to the intermittent movement of the rectangular sheet, thereby selectively plating the rectangular sheet in the lengthwise direction continuously or intermittently.
Abstract:
Liquids and semiliquids, such as thixotropic gels, oil and greases, are delivered to a discharge means according to a method and through the use of an apparatus powered by hydraulic fluid under pressure which is controlled by a valve for passage to a hydraulic motor that is, in turn, coupled to a pump used to withdraw and pressurize the material for delivery by a conduit line to the discharge means having a discharge orifice that is either nonclosable or synchronously opened. The material is discharged by controlled pressurization which is initiated and terminated by controlling the flow of hydraulic fluid to the hydraulic motor in response to actuation of a trigger or switch on the discharge means. A discharge gun and a lubricator collar are two preferred forms of the discharge means.
Abstract:
An apparatus for the direct cooling of a strand, especially during the continuous casting of steel, incorporating strand guide segments equipped with spray nozzles for the application of a cooling agent to the strand. The spray nozzles are arranged at rotatable holders, each holder is equipped with at least two nozzles. A drive mechanism is provided for the stepwise or incremental rotation of such holders and there are provided infeed means for delivering the cooling agent to the spray nozzles.
Abstract:
The disclosure relates to a method and to an apparatus for cooling continuously cast webs of metal. Several coolant jets are produced continuously and at least two jets are projected to a hotter, slowly cooling zone of the surface of the webs.
Abstract:
Coating apparatus is disclosed which has a spray tip characteristic tailored to produce an atomized spray patter which is substantially triangular in cross section. This results in a coat distribution uniform particularly throughout a given width of a substrate. Means are also provided to hold the spray tip wide open for maintenance purposes.
Abstract:
Liquid is distributed at a substantially desired uniform rate per unit area on a surface having a dimension which varies in a predetermined manner by projecting at the surface a divergent stream of the liquid from a nozzle which can be moved towards and away from the surface, the rate of supply of liquid to the nozzle being substantially proportional to the distance between the nozzle and the surface. The invention is useful in applying a wear-resisting liquid coating to the rolls of hot metal rolling stand, the chosen rate of discharge being sufficient to mitigate wear of the work rolls without derogating from their performance.
Abstract:
A coating device having a dusting tube into which the coating dust is blown from opposite sides to provide a dust suspension for applying a uniform coating to a workpiece passing therethrough, and a larger chamber surrounding the dusting tube for confining the excess suspension exiting from the open ends of the dusting tube from which a portion of the dust suspension is recirculated back into the dusting tube.
