Abstract: A gas burner includes a gas reservoir, a combustion device, and a tilt safety device fluidly connecting to one another. The tilt safety device includes first and second seats including first and second gas passages respectively, an elastomer disposed on the second seat and including a section defining a stop, a control mechanism including a lever adjacent to the elastomer and including a first contact area and at least one second contact area selectively engaging with a pusher which engages with the stop, and a gas flow channel connecting to the second gas passage and a hole extending through the elastomer and the first gas passage and including the first and second ends thereof including the stop disposed therebetween. The first and at least one second contact areas space from the elastomer at first and second heights respectively. The second height is less than the first height.

Abstract: The invention relates to a nozzle arrangement (6) adapted to supply at least one fluid-phase additive into a storing compartment (4) of a textiles treatment apparatus (2), in particular an exhaust air and/or condenser dryer, a refreshment apparatus or a washing machine having drying function. The nozzle arrangement comprises at least one nozzle (8), each being adapted to feed an additive; and at least one trapping device (10) adapted to trap and/or to remove liquid and/or particles leaving the at least one nozzle (8) or forming at or close to said nozzle. Further, the invention relates to an additive supply arrangement (6, 18, 20, 22, 12) adapted to supply at least one additive, comprising at least one nozzle (8), each being adapted to feed an additive; at least one additive supply source (12); and at least one fluid channel (18, 20) connecting the at least one additive supply source (12) to the at least one nozzle (8); wherein at least one fluid channel comprises at least one capillary element.

Abstract: A cleaning method uses a cleaning agent in which microcapsules are dispersed therein. Each of the microcapsules encapsulates a gas precursor, which is capable of undergoing a phase transition to a gas phase by application of ultrasonic wave energy. In the cleaning method, clothing to be cleaned is wetted with the cleaning agent, and then an ultrasonic wave is applied to the clothing to cause the microcapsules to expand and explode, releasing gas. Explosion energy of the microcapsules contribute to remove dirt stains from the clothing. In order to facilitate absorption of the cleaning agent, a smaller ultrasonic wave may be applied to the article before applying the ultrasonic wave for explosion.

Abstract: A control valve for use in a liquid-carrying system, such as a heating or cooling system, containing a differential pressure governor which keeps the differential pressure between the inlet and the outlet constant. The control valve also includes an arrangement for setting and adjusting the maximum flow of liquid through the valve. This arrangement comprises a flow valve having two cooperating valve members (4 and 6), which are arranged in the flow path and are constructed as two concentric rings, each of which has a recess extending about 180 degrees in the circumferential direction. The outer ring (4) is stationary relative to the valve housing, while the inner ring (6) may be displaced in the circumferential direction by means of a rotatable handle, whereby a greater or smaller overlap between the recesses may be provided. The maximum flow amount may hereby be set manually.

Abstract: A fuel tank venting system for a boat (10) includes a fuel tank (12) the interior of which is open to a filler tube (14) and a vent line (18). A liquid separation and recovery device (20) is connected to the vent line and an outlet line (28) which is open to atmosphere. Vapor delivered to the device through the vent line enters an inlet (24) and passes through an opening (64). The vapor then passes through a screen (86), around a sphere (82) that is buoyant in the liquid fuel, and escapes from the device through an outlet (26). When liquid fuel enters the device, the sphere rises blocking flow to the outlet. The trapped liquid passes through an opening (48) into a cavity (42). The liquid entering the cavity displaces a spring loaded piston (56). When liquid is no longer being delivered to the cavity, the piston pushes the liquid back out the inlet and down the vent line to the fuel tank.

Abstract: An improved radiator vent valve and syphon tube assembly is provided, the vent valve including a valve body and a threaded valve nipple adapted to engage a wall of a radiator. The nipple defines a passage communicating between the interior of the radiator and the interior of the valve body and the syphon tube drains condensate from the interior of the valve body into the radiator. The syphon tube includes a tubular portion adapted to be inserted into the passage defined by the nipple, the tubular portion including resilient tabs about its outer surface which permit insertion of the tubular portion into the nipple and after insertion, yieldably engage an inner surface of the nipple. The syphon tube also includes a generally trough-shaped portion coplanar with the tubular portion and another trough-shaped portion oriented to direct the flow of condensate downward when the tubular portion is horizontal. The three portions of the syphon tube provide a substantially continuous flow path.
