摘要:
Some embodiments provide an interface unit interfacing with an irrigation controller, comprising: a housing; a controller configured to instruct an interruption of a watering schedule executed by the irrigation controller, the interruption based on one or both of sensed temperature and sensed rainfall amount, and based on one or both of user entered temperature and rainfall threshold parameters; a switching device coupled with the controller, and configured to cause the interruption in response to signaling from the controller; and a user interface comprising: a plurality of user input devices configured to provide signaling to the controller based upon user's engagement, and configured to allow the user to define the temperature and rainfall threshold parameters; and a user display comprising a display screen; wherein the controller is configured to cause the display screen to display a plurality of pictorial representations that in combination convey whether irrigation is being interrupted.

Methods and apparatus are provided herein for permitting or interrupting irrigation using sensor equipment. In one embodiment, a method for controlling irrigation comprising the steps of: generating an indication representing the amount of rain fall at a sensor unit; transmitting a signal comprising at least the indication from the sensor unit to an interface unit, wherein the interface unit is adapted to cause an interruption of programmed watering schedules of an irrigation controller; receiving the signal at the interface unit; determining, based at least on the indication from the signal, whether irrigation should be interrupted; and generating an interrupt command to interrupt irrigation.

There is disclosed herein a liquid spray gun which includes an improved heat dissipation system and an improved leakage flow recirculating system.The improved heat dissipation system results from an improved and stronger air flow through the gun housing and around the electromagnetic coils. The improved air flow is created by a venturi or aspiration effect at the spray tip created by the action of the piston pump in spraying liquid at high velocity reducing the air pressure adjacent the tip. The internal portion of the housing communicates with the low pressure area so air in the housing is drawn from the housing to the low pressure area. Vents are provided in the housing adjacent the electromagnetic coils for outside air to be drawn into said housing over said coils and to the low pressure area, thus improving air flow and heat dissipation.

A pressurized paint supply system for delivering paint or other coating material under pressure to a variety of interchangeable paint applicators. The invention is also concerned with an improved pad assembly for trimming purposes and to an improved pressure-tight joint which can be used with any of the accessories used in the system of the present invention.
摘要:
A manually operable power unit for paint scraping and the like comprising a casing with a longitudinal axis having a handle to enable portable use by the operator, an electro-magnetic motor mounted within the casing including a stator and an armature mounted relative to the stator for movement parallel to the longitudinal axis, a bladeholder connected to the armature reciprocally movable in unison together, the bladeholder extending generally parallel to the longitudinal axis of the casing and the direction of movement of the reciprocating armature to provide contemporaneous colinear movement of the bladeholder and the armature to substantially eliminate bending forces on the bladeholder imposed by the electromagnetic drive forces of the motor, the motor being operable on energization to move the armature and the bladeholder from a starting position to an extended position, and a spring connected to the bladeholder which is compressed when the bladeholder is moved to its extended position and the spring operating to move the bladeholder to its starting position upon release of the electromagnetic forces generated by the motor.
摘要:
A hand held tape dispenser and applicator having a light weight plastics material housing with a hollow hub at one end mounting an exposed roll of pressure sensitive adhesive tape and a hand grasped hollow finger extending from the hub to a dispensing outlet where a feed roll receives the adhesive foil of the tape and directs the opposite face to a press roll for applying the tape to a surface. A thumb operated slidable trigger on the top of the finger selectively rocks a cutter head over the press roll to sever the dispensed tape. The housing is longitudinally split with the two mating components snap fitted together and easily pulled apart to insert the tape roll and thread the tape over the feed roll. A belt clip receives the hollow hub permitting the applicator to be releasably suspended from the waist belt of a user.
