摘要:
A method of controlling rotation of a water distribution plate supported on a shaft and adapted to rotate about an axis defined by the shaft by reason of impingement of a stream emitted from a nozzle on grooves formed in the plate, the method includes: (a) slowing the rotation of the water distribution plate intermittently so as to create intervals of relatively slow and relatively fast rotation and thereby correspondingly increase and decrease, respectively, a radius of throw of the stream or improve the uniformity of water distribution; and (b) continually changing circumferential locations of the intervals about the axis.

A method of monitoring sodium hypochlorite usage, which includes providing a chemical system comprising: a tank of known capacity mounted upon a scale, the scale being capable of generating a series of signals related to the weight of the tank when empty and at various levels of fill; and a system controller for receiving the series of signals from the scale relating to the weight of the tank when empty and at various levels of fill; inputting into the system controller the series of signals from the scale relating to the weight of the tank when empty and at various levels of fill with sodium hypochlorite; inputting into the system controller a concentration of the sodium hypochlorite upon filling of the tank; tracking an age of the sodium hypochlorite within the tank to obtain a percent concentrate of sodium hypochlorite; and displaying usage of sodium hypochlorite on a display.

A mobile station includes an adjustable member for increasing a separation distance between an audio signal output device and an electronic circuit to reduce EMI proximate the audio signal output device caused by the electronic circuit. In one embodiment, the adjustable member comprises a slide member that extends at least a portion of the audio signal output device away from the electronic circuit to increase the separation distance. In another embodiment, the adjustable member comprises a pivot member that rotates the electronic circuit (or audio signal output device) away from the audio signal output device (or electronic circuit) to increase the separation distance. In any event, increasing the separation distance between the audio signal output device and the electronic circuit decreases the EMI proximate the audio signal output device, and therefore EMI effects on external circuits proximate the mobile station, such as a hearing aid.
摘要:
A system for mounting an object such as a flat screen television on a surface such as a wall. A mounting template is fastened to the surface and defines multiple sets of openings corresponding to multiple mounting configurations. Wall brackets are removably secured within the openings and are then fastened to the surface. Object spacers are fastened to mounting locations on the object corresponding to the mounting configuration of the wall brackets, and are connected to the wall brackets to secure the object to the wall. A level may be secured within the mounting template. The mounting template may include fold lines to facilitate packaging and storage of the mounting template.

A dual-mode sprinkler includes a nozzle arranged to supply a stream to a rotatable water-distribution plate. The sprinkler can be adjusted between free-spinning and retarded or braked rotation, enabling multi-use applications for the sprinkler.

A rotary sprinkler includes: a shaft having a cam, the cam having a plurality of radially outwardly projecting cam lobes; a rotatable water distribution plate adapted to be impinged upon by a stream emitted from a nozzle causing at least the water distribution plate to rotate; a hesitator assembly including a stationary housing having a sealed chamber at least partially filled with a viscous fluid, with at least the cam and the cam lobes located within the chamber; a rotor ring located within the chamber in substantially surrounding relationship to the cam, the rotor ring loosely located within the chamber for rotation and translation, the rotor ring provided with at least two hesitator lobes projecting radially inwardly and movable laterally into and out of a path of rotation of the cam lobes, and a first plurality of radially outwardly projecting teeth selectively engageable with a second greater plurality of teeth provided on an inner wall of the housing; and wherein rotation of water distribution plate is slowed during intervals when one of the cam lobes engages and pushes past a respective one of the hesitator lobes, the cam lobe exerting both rotation and translation forces on the rotor ring, with one of the first plurality of teeth on the rotor engaging one of the second plurality of teeth on the housing wall.

A sprinkler assembly includes a housing having an open side; a sprinkler body supported at one end of the housing and adapted to receive a nozzle. A nozzle magazine is attached to the housing along the open side and holds plural nozzles selectively alignable with said sprinkler body. An actuator is arranged to move a selected one of the plural nozzles from the nozzle magazine into the sprinkler body.
