Abstract: A method and apparatus for dispensing welding flux involving a flux supply and dispensing system comprising a tank assembly that includes an upper flux receiving chamber, a lower flux dispensing chamber, and a flux transfer chamber intermediate the upper and lower chambers. Flux is supplied to the flux receiving chamber either by a vacuum pick up arrangement or a suitable gravity or mechanical feed arrangement, and screened. The floors of the upper chamber and transfer chamber are each ported and equipped with separate plug valves arranged to move vertically to open and close with a plug type fit the respective ports for sequentially transferring a welding flux charge first from the upper chamber to the transfer chamber, and then from the transfer chamber to the lower dispensing chamber, under the control of a sealed pneumatic actuation system that keeps the flux from fouling the moving parts involved. Dispensing of the flux from the lower chamber is by way of either gravity feed or fluidized feed through a hose to the point of use.

Abstract: A mounting and guide assembly for cutting torches for mounting same on a movable frame for movement over the workpiece, with the mounting and guide assembly comprising a torch mounting arrangement including a vertically disposed double acting hydraulic cylinder and piston device having a piston rod structure projecting from either end of its cylinder and mounting at the lower end of the piston rod a torch mounting head that releasably and adjustably secures the torch in place for positioning the torch nozzle for correct application to the workpiece. The torch mounting head is equipped with a feeler or guide member mounted for a lost motion movement range axially of the torch nozzle and having a plurality of feeler elements in coplanar arrangement that ride on the workpiece in spaced relation about the nozzle for maximum sensitivity of vertical undulations in the workpiece. The piston and cylinder device is incorporated in a hydraulic system that includes a hydraulic pressure liquid and a hydraulic pressure liquid flow orienting or directional control valve of the mechanical servo type, for supporting the torch and moving same axially of its nozzle. The feeler or guide member and the servo valve are operably connected to the torch mounting head for translating the movement of the feeler member in its lost motion range, due to elevational changes in the workpiece, as the torch moves across the workpiece, into adjustment of the servo valve to maintain the torch nozzle at the desired predetermined spacing above the workpiece, as torch cutting proceeds.

Abstract: A system of making molds for investment casting in which the patterns are formed from, and the sprue form is coated with, polyethylene glycol having a molecular weight in the range of from approximately 1,300 to approximately 1,600, or its equivalent and having admixed therein as a filler powdered graphite, in which the graphite comprises in the range of from about 35 per cent to 60 per cent by weight of the pattern forming material. The patterns are molded to the desired shape, and to include a gate section, and they are adhered to the sprue form in spaced apart relation by fluidizing the gate section end to make a welded connection with the sprue form coating. The mold is then formed about the patterns that are adhered to the sprue form, leaving the pour cup end of the sprue form exposed, to which heat is subsequently applied to sufficiently fluidize the sprue form coating so that the sprue form can be drawn out of the mold thereby leaving the sprue opening. The sprue form coating remaining in the mold sprue and the patterns are then removed without heating the mold by leaching with water, utilizing mechanical and/or chemical agitating after which the mold may be heated sufficiently to dry same for use as an investment casting mold.
