Abstract: A process of making printed circuit boards in which the individual substrates involved are hot set formed from a suitable thermosetting resin and filler composition, with the cure being limited to the resin B stage. The side surfacing of the individual substrates that is to bear the metallic electrically conductive circuiting is catalyzed and then electrolessly plated with copper or the like electrically conductive metallic material to a thickness in the range of from about 50 to about 100 millionths of an inch, and thereafter the thusly plated substrates are hot set to fully cure same and perfect the bond between the substrate and its plating.

Abstract: A label assembly arrangement with label end finger hold capability for the individual labels, in which the label assembly comprises a carrier sheet and a plurality of pressure sensitive adhesive backed labels that are shaped to be expeditiously separated from the carrier sheet and centered on the desired substrate surface by finger gripping of the label end portions, which in accordance with the invention have the adhesive side of same masked at either end of the label to protect the adhesive during handling. The masking is effected by masking sections delineated and severed from the carrier sheet and removed therefrom when the individual labels are peeled from their carrier sheet.

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.

Abstract: A tape and tape reader for industrial process programmable controller systems in which the I/O functions for process steps have been laid out in sequentially consecutive binary notation fashion computer data word form, in the order of sequence of the process steps, in accordance with which the tape is a ribbon that is delineated to have applied to same the computer data word indicia in modularized group or set form, in which groups or sets the computer data words for the consecutive process steps are sequentially arranged transversely of the tape, with succeeding groups or sets following in sequential order, wherein the computer data word indicia is manually marked on the tape binary notation system fashion, with electrically conductive marking material, and the reader is formed for pull through application of the tape therethrough and includes an electrical contact arrangement for electrically sensing the tape markings in consecutive word group or set form, with continuous manually induced movement of the ta

Abstract: A programmable controller system for controlling industrial processes in which the system includes a central processing unit including a random or other access memory, a programming tape, a tape reader for sensing computer data bits on the programming tape and connected to the processing unit for storing the data bits in memory, and means for connecting I/O devices to the processing unit, wherein a work sheet is employed that is arranged for manual marking of the program process steps in terms of I/O functions thereon in sequentially consecutive binary notation fashion computer data word form, in the order of sequence of the process steps.

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.

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.
