Abstract: A self steering blade guide for a band saw, including a support block which can be rigidly fixed to the frame structure adjacent the blade and which supports a steering block having a blade receiving slot with side surfaces adjacent the flat sides of the blade and engagable therewith upon the sideways deflection of the blade, and a mounting connection between the steering block and the support block for permitting pivotal movement of the steering block about an axis parallel to the direction of travel of the blade, the axis being adjacent to or forward of the cutting edge so that the blade will pivot about the axis with the steering block when deflected, and through action on the blade by the material being cut the blade will automatically be returned to its normal position parallel to the direction of feed of the material through the blade.

Abstract: A heat exchanger is used in combination with a dishwasher of the type having a sump, a washing spray assembly, a circulating pump which pumps washing fluid from the sump through the washing spray assembly, a rinsing spray assembly, a source of fresh rinsing water which flows through the rinsing assembly, a booster heater for heating the rinsing water to a predetermined temperature and a drain line for draining excess washing solution from the sump. The heat recovery system includes a heat exchanger in which fresh rinsing water flows in heat exchange relation with the excess washing solution from the sump before the rinsing water reaches the booster heater. A rinse valve controlling the flow of rinsing water cooperates with a pump located on the drain line so that the rinsing water and the washing solution flow through the heat exchanger at only preselected times during the operating cycle of the dishwasher.

Abstract: In a band saw (10) particulaly adapted for cutting meat, blade scrapers (25, 26) remove debris from the band saw blade (18) and throw it laterally and forward of the blade (18) into an enclosure (40), which can be removed without the use of tools for cleaning and for disposing of the collected debris. The location of the blade scrapers (25, 26) is slaved to the location of the saw blade (18) to automatically maintain the proper relationship for most efficient debris removal without adjustment.

Abstract: In a band saw (10) particularly adapted for cutting meat, blade scrapers (25, 26) remove debris from the band saw blade (18) and throw it laterally and forward of the blade (18) into an enclosure (40), which can be removed without the use of tools for cleaning and for disposing of the collected debris. The location of the blade scrapers (25, 26) is slaved to the location of the saw blade (18) to automatically maintain the proper relationship for most efficient debris removal without adjustment.

Abstract: A method and apparatus for feeding strip stock into a machine, such as a press, in which opposed feed rolls are closed on the strip stock for frictionally engaging the strip stock and one thereof is accelerated from a stopped position and is then decelerated back to a stopped position for a feed cycle with a control system provided for determining the precise point during a feed cycle to initiate deceleration of the feed roll. At the end of a feed cycle, the feed rolls are again separated.
