The column carries a monitoring table above the support and is vertically shiftable on a gantry frame. The gantry frame rolls horizontally relative to the shell of the vessel. The shell of the vessel is mounted on a turntable to which a generally reciprocatory rotary movement is imparted.

Abstract: A system for forming zigzag wire binder material in a continuous strip, storing the strip as it leaves the forming station, and severing lengths as needed at an adjacent station at which the binder lengths are inserted in books. The invention permits the binder strip forming mechanism and the binder cutting and inserting unit to be at a single location because the storage mechanism placed between these two units is responsive to speed differences between the strip forming and binder inserting units to temporarily stop one unit or the other until the length of binder strip in the storage unit is brought within a certain range. The inserting unit has novel means for forcing the opposite ends of the binder loops into the book holes, making the unit especially useful for heavy count books. This novel inserting means includes two series of pins which move in opposite directions to force the loops into the holes.

Abstract: An improved anode connector assembly for a cathode ray tube comprises a resilient rubber cap having a cavity receiving a U-shaped metal bracket which opens toward the outer end of the cavity. The bracket is interengaged with the cap against displacement relative thereto, and a bare end portion of an insulated anode supply conductor extends through the cap into overlying relationship with the bridge portion of the bracket and is bent to form a loop. A U-shaped metal clip having leg portions for engaging the anode button has its bridging portion disposed in the cap cavity in overlying relationship with respect to the conductor loop. A threaded fastener extends through the bridging portion of the clip, through the loop and into threaded engagement with the bridging portion of the bracket. The fastener secures the conductor wire between the bridging portions and secures the clip to the bracket against displacement from the cap cavity.

Abstract: An electronic programmable adapter for connecting an integrated circuit element having a pin array to an electrically dissimilar socket array. It features slideably mounted connector elements which can be selectively operated to be either disconnected or connected to their corresponding pin elements to make possible external electrical connections between adapter elements elsewhere in the array.

Abstract: The heat treatment of a continuous band or sheet of metal as the same travels through a plurality of stages in a protective atmosphere, between conveying rollers, by applying direct-current electricity to the rollers for inclusion of the travelling sheet in the circuit therebetween. The charged rollers in the initial stage are spaced more widely from one another than those in the later stage, to compensate for the lower resistivity of the metal in the former, so that the Joule effect or I.sup.2 R factor in the stages are substantially equalized. The protective atmosphere of oxidizing, reducing or inert gases which encompasses the sheet, is confined in chambers of galvanized iron sheeting and the like, the walls of which are in close proximity to the travelling sheet, so that lesser amounts of reacting gases are necessary.

The terminal connecting block is used in combination with a bracket for mounting the block on a surface.

Abstract: The present invention discloses an apparatus for collecting hot wire rod at the output of a rolling mill and cooling the same in such a manner that the same is prevented from being oxidized.

The coiler is enclosed in a bell-shaped casing immerged in a cooling fluid so as to define and air-tight sealing. The spirals of wire carried by the conveyor are cooled before loaving the cooling fluid down to a temperature lower than the oxidation temperature thereof.
