    Abstract: A method of welding two plastic surfaces together comprises the steps of: juxtaposing the surfaces, heating the surfaces to a temperature approaching the flashpoint of the plastic surfaces to liquify the surfaces, removing a portion of the liquified surfaces to expose unoxidized surfaces therebeneath and immediately thereafter bringing the unoxidized surfaces into abutment with one another. The heating of the juxtaposed surfaces is accomplished by contacting the surfaces with a heated tool which has been preheated to a temperature approaching the flashpoint of the plastic surfaces. The tool also serves to remove a portion of the liquified surfaces. Various apparatus are disclosed for carrying out the method. In one embodiment, the apparatus includes a reciprocating heated tool. In another apparatus, the heated tool is a rotating disc. In yet another apparatus, the heated tool is a continuously circulating band. In yet another embodiment of the invention, the apparatus comprises a hand-held portable, heated tool. Various plastic articles are welded utilizing the method and the apparatus disclosed.

    Abstract: A vibrating spray apparatus and method of spraying which produces a spray pattern of substantial uniform density, the spray apparatus including a spray tube that is free at one of its ends, means to supply liquid to the spray tube from the other end thereof, a motion transmitting device associated with the spray tube to impart vibrations of sufficient magnitude to the spray tube to cause the free end of the tube to move in an orbital path. The method of the present invention involves the movement of a stream of liquid in an orbital path wherein the liquid is discharged while moving in the orbital path to produce a pattern of uniform density.

    Abstract: A sector spray device comprising a stationary feedpipe having at its lower end a stationary discharge control cap, which possesses a discharge slot. The sector spray device further comprises a drive means for rotating a sleeve to which are attached discharge tubes that are from time to time during their circle of rotation in fluid communication with the discharge slot of the control cap. Thus, liquid passing through the feedpipe will be discharged through only those tubes in fluid communication with the discharge slot. In this way, the liquid is sprayed in a constant sector-shaped pattern that can be limited to 90* or less, depending upon the discharge slot. Also, where the present invention uses a control cap with a discharge slot, a selector can be employed to change the position of the discharge slot, and thereby cause the sector-shaped pattern to be moved accordingly to a new location. Furthermore, the width of the discharge slot in the cap can be varied by movement of an indicator.
