Abstract: A step controller for a water heater having a plurality of individual electrical heating elements changes the number of energized elements to maintain a predetermined minimum temperature. A thermistor sensor monitors the temperature of the water and generates a proportional signal. Preset potentiometers establish set point temperature signal and a dead band signal. The number of "on" elements is related to the difference between the sensed water temperature and the preset water temperature divided by the dead band factor. The heating elements are turned "on" and "off" in a predetermined sequence whenever a change is required. The sequence includes turning on the heating element which has been off for the longest period and turning off the heating element which has been on for the longest period.

Abstract: This disclosure illustrates and describes a bottom closure structure for a liquid carrying, thermoplastic coated paperboard carton or container wherein the overlapped and sealed areas are formed so as to extend in an "X"-shaped configuration across the bottom, with minimal raw edge exposure on the inside. The shapes of the four main bottom panels of the blank from which the carton is formed are such that they accommodate interdigital nesting or overlapping with respect to the bottom section of an adjacent blank prior to the cutting operation on a paperboard roll, thereby resulting in a narrower roll and, hence, a substantial paperboard savings.

Abstract: An elongated energy-absorbing bumper assembly including energy-absorbing elastomeric or foam material extending between a rear mounting surface and a front impact surface with the material defining a hollow recess extending thereinto from the rear mounting surface and positioned between the ends of the assembly. The elastomeric foam material extends to the rear mounting surface at both ends of the hollow recess to define block-like end portions of the elastomeric material. A structural member extends between the block-like end portions of elastomeric material with the ends of the member embedded in the elastomeric foam material. The elastomeric material is the sole support and means of positioning the member so that the member is allowed unguided movement with the elastomeric material in multiple directions upon impact.

The chestplate, backplate and arch each comprises a separate, discrete piece of relatively rigid material, the arch being mounted for upward swinging movement with respect to the chestplate and backplate whereby freedom is provided for raising the arms above a horizontal position by permitting upward movement of the arm at the shoulder without substantial interference from the arch.

Abstract: The cleated belt forage conveyor of the invention is directed to a forage belt conveyor in which the belt in service is protected against side discharge of conveyed forage by upstanding and intermittent central cleats and outwardly spaced side cleats. Sealing strips extend above the belt in the spaces between the respective central and side cleats to limit outward movement of the bulk of the forage and an edging extends on each side of the belt to prevent spillover. In the event of some side discharge from the belt to the inside of the lower reach of the belt, a plow overlying the inside of the lower reach of the belt directs the forage for discharge to vibrating deflector plates which deflect the forage to the bottom of the housing of the conveyor to be carried by the cleats to the input side of the conveyor and around the idler pulley for reconveyance.
