Abstract: Apparatus for recording and displaying a graphic representation of the operating performance of a railroad locomotive by monitoring the response of its engine to a throttle control setting. The apparatus includes a chart paper recording device driven in relation to time and a marking mechanism actuated by a governor and referenced to its balance position at normal operation of the locomotive engine. The marking mechanism includes a pair of fixed styli and a movable stylus for producing a graph on the chart paper. The pair of fixed styli produce a pair of spaced-apart parallel datum traces on the chart paper wherein the area therebetween represents the normal governor balance position for a specified throttle setting. The movable stylus actuated by the governor produces a single trace on the chart paper relative to the parallel datum traces and represents the movement of the governor as it seeks to maintain its normal balance position.

Abstract: A transfer apparatus in a glass heat treating operation for removing a horizontally disposed sheet from a horizontal glass processing line and reorienting it into a substantially vertical plane for final processing in a vertically oriented quench operation. The transfer apparatus constitutes a pivotal end section of a horizontal conveyor system and is adapted to be equipped with glass bending fixtures.

Abstract: A method for preventing the dropping of individual bricks from a sprung arch roof employed in a continuous tank-type glass melting furnace, the dropping of the bricks normally occurring during heat-up of the furnace. The slightly tapered bricks employed in constructing the roof are oriented with their long axis in the vertical direction and, as heating occurs and the structure differentially expands and the bricks dry out, some become sufficiently loose to drop from the roof into the tank of the furnace. In visually observing the interior surface of the roof during heat-up, it can be seen which bricks are settling and likely to drop therefrom. These bricks are pulled up through the roof from above by a suction cup and mortar is placed around the bricks. The bricks are then dropped back into place with the mortar holding the bricks until they become wedged firmly in place as the temperature of the roof increases.

Abstract: A furnace for heat treating vertically depending sheet material moving through an enclosed heating chamber, the furnace having entrance and exit openings in opposed end walls and a slot in the roof extending between the openings. The depending sheet material moves through the heating chamber suspended from a trolley supported above the slot, which trolley has hanger rods projecting through the slot. The entrance and exit openings are closed by doors, and an air curtain directed across the slot provides a pressure barrier which, together with the doors, prevents the flow of heated gases from and within the heating chamber.

Abstract: A two-piece quick connect-disconnect coupling connecting a conveyor roll to a drive train. The coupling comprises a first section rigidly secured to the conveyor roll and a second section operatively connected to the drive train and a retaining screw detachably connecting the second coupling section to the roll and locking the gears of the first and second coupling sections together in an engaged, intermeshing relation.

Abstract: A window formed of a glass sheet having a combined electrical heating circuit and bending circuit imprinted thereon. The heating circuit comprises a series of longitudinally extending conducting lines interconnecting spaced bus bars. The bending circuit includes resistance elements in the form of electrically conducting paths extending transversely of the sheet along the lines about which the sheet is to be sharply bent and which intersect the longitudinal conducting lines of the heating circuit. Interruptions are formed along the bus bars of the heating circuit in a manner isolating the latter from the bending circuit during the formation of sharp bends in the glass sheet.
