| 20090013656 | Two-Piece Strapping Tool - A two-piece strapping tool having a manual tensioner and a battery-operated sealer is disclosed. The tensioner is a feedwheel tensioner that uses a serrated feedwheel to grip a first portion of the strap and a tension gripper to hold a second portion of the strap in a stationary position. The tensioner is configured to matingly receive the sealer between the tensioner's support legs such that the sealer may readily engage the overlapping portions of the strap to be welded. The sealer is battery-operated and uses a vibrational-type weld assembly driven by an electrical motor to weld overlapping portions of the strap. The sealer also includes a cutting assembly to sever the welded strap from a strap source. | 01-15-2009 |

| 20110094544 | WAREWASH MACHINE WITH SOIL DETECTION - A warewash machine includes a tank for holding liquid to be sprayed on items in a spray chamber and a recirculation line for delivering liquid from the tank to nozzles for spraying. A sensor arrangement is provided for monitoring condition of tank liquid, the sensor arrangement including an light emitter and a light receiver. A control is provided for energizing the light emitter and monitoring output of the light receiver, wherein the control is configured to vary the energization level of the light emitter during sensing to extend a useful range of measurement the sensor arrangement. The sensor arrangement may be located in line with or in parallel with a drain line of the tank. | 04-28-2011 |
| 20110095010 | WATER TANK HEATER WITH PREDICTIVE HEATER FAILURE FEATURE - A water heating system includes a tank for holding water and a resistive heating element associated with the tank for heating water in the tank. A control is connected for monitoring at least one resistance parameter of the resistive heating element as power is applied to the resistive heating element, the control configured to output a fault signal if the monitored resistance parameter exceeds a set threshold. The monitored parameter may be one or more of (i) a rate of resistance change during heater start-up, (ii) a rate of resistance change during steady state heater operation or (iii) a heater resistance corresponding to a set point in time following heater start-up. | 04-28-2011 |
