Abstract: A shower head (10C) has at least one mixing chamber (24) having an air inlet (18) for connection to a supply of pressurized air and a water inlet (22) for connection to a supply of pressurized water so that, in use, the air breaks the water up into droplets in the mixing chamber. The mixing chamber further has at least one outlet (32) so that, in use, the water droplets and air exit the shower head to form a shower of water droplets having a mean trajectory. The or each outlet is arranged so that, in use, at least a substantial proportion of the water droplets exit the shower head so that their individual trajectories on leaving the shower head are offset from the mean trajectory of the shower head and converge towards the mean trajectory of the shower head. This can result in a more uniform distribution of water droplets in the shower pattern. A single annular outlet may be provided, or a plurality of separate outlets.

Abstract: A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. In embodiments, rotation of a portion of the marker positioner advances and/or retracts the marking device with respect to the flow of air through the air outlet, thereby altering the angle and/or amount of air that contacts the marking device during spraying. In another embodiment, the marker positioner includes a locking lever for engaging against the marker device nib and/or housing.

Abstract: A firefighting medium is allowed to escape from a nozzle through apertures, the nozzle being provided with an internally arranged valve in sealing contact with a valve seat until the valve is released from its sealing position. The release is caused by a heat sensible release mechanism acting on the valve, whereby the sealing effect of the valve is relieved. A locking force required for maintaining the sealing effect by a removable cap or cover is provided, attached to the nozzle front, the locking force being established between at least two interacting surfaces. By releasing the sealing effect of the valve by removing the locking effect between the two interacting surfaces, the cap or cover is allowed to drop off its seat on the nozzle, relieving the press causing the sealing effect on the valve of the nozzle, the removal of the cap or cover caused by releasing mechanism.

Abstract: In a method of controlling a rotary sprinkler, a first angular position and a first watering distance are accessed from memory using a controller. A first electric motor is driven using the controller based on the first angular position. A head comprising at least one nozzle is rotated to the first angular position responsive to driving a first electric motor. A second electric motor is driven using the controller based on the first watering distance. A valve is positioned in a first valve position responsive to driving a second electric motor. Water is discharged through the valve and the at least one nozzle. The head is held at the first angular position for a first time period based on the first watering distance.

Abstract: A combined pilot valve mechanism and a shower system are applied with the combined pilot valve mechanism. By switching to close the control hole, the first water diversion hole or the second water diversion hole to control the pressures of the pressure cavity, the valve spool is driven to move to alternately close the first outlet or the second outlet, so that the inlet waterway is switched to connect to the first outlet waterway, the first water diversion hole or the second water diversion hole. As the shower system is applied with a combined pilot valve mechanism, which utilizes the control hole to switch the waterways, thus preventing the main pipe from great water pressure. The diameter of the control hole can be smaller, so that the water pressure of the button mechanism can be ignored, only friction and light elastic force of the spring exist.
