A mechanism for generating a flame jet has a volume formed of at least one vertical structure and two opposing horizontal structures. A rotatable fan is located within the volume, and is rotatable in a plane generally parallel to the planes of the horizontal structures. The mechanism also contains means for igniting a combustible gas which is contained within the volume, to propel a flame jet outside of the volume.

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.

The invention relates to a ware washer (40, 50) and to a method for operating a ware washer (40, 50) which is designed as a programmable machine (40) or as a conveyor ware washer (50) and which has at least one pump (11, 11-1, 11-2, 11-3, 11-4, 11-5, 11-6), at least one line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6) connected to the pump (11, 11-1, 11-2, 11-3, 11-4, 11-5, 11-6), and at least one nozzle system connected to the line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6) and having at least one nozzle (13, 13-1, 13-2, 13-3, 13-4, 13-5, 13-6, 13-7), a liquid being supplied at least intermittently to the at least one nozzle (13, 13-1, 13-2, 13-3, 13-4, 13-5, 13-6, 13-7) via the line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6). Furthermore, a sensor device (30, 30′, 30″) connected to a control device (20) is provided for detecting a profile of the hydrostatic pressure (Pi) of the liquid in the line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6) and for comparing the detected pressure profile (Pi) with a predetermined pressure profile (Ps). In order to achieve the situation where potential deviations of the water circulation capacity or potential deviations of the nozzle pressure can be ascertained and automatically reacted to correspondingly in order to counteract the deviation of the water circulation capacity, according to the invention the control device (20) is designed, in the event of a deviation of the detected pressure profile (Pi) from the predetermined pressure profile (Ps), automatically either to carry out a regulating action on the operation of the ware washer (40, 50) as a function of the size and the time gradient of a difference between the predetermined pressure profile (Ps) and the detected pressure profile (Pi) or to issue a fault warning via an optical and/or acoustic interface (22) or to issue a fault warning to a remote maintenance station via a remote control interface (23).

A combustion-powered fastener-driving tool includes a combustion-powered power source, a workpiece contact element reciprocable relative to the power source between a rest position and a firing position, a control system operationally associated with the power source, a trigger connected to the control system providing operator interface with the control system. The control system is configured so that an operator may select between a sequential firing mode in which the trigger must be released between firings, and a repetitive cycle mode in which the trigger is continually depressed between firings. The trigger is connected to the control system so that at least one of the frequency and duration of pulling of the trigger converts the operating mode from the sequential mode to the repetitive cycle mode.

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.
