  • Patent number: 6647319
    Abstract: A simple, inexpensive multi-station sprinkler controller has three pushbuttons: the first selects one of a plurality of predetermined combinations of watering cycle durations and repetition rates; the second selects a starting time, and the third initiates a manual cycle. On power-up, the controller defaults to a predetermined operating cycle and start time. A short circuit at any station stops watering and initiates a fault indication that identifies the short-circuited station. All status information is conveyed by the scrolling, illumination, flashing and/or blinking of one or more of a small set of LEDs. In another embodiment, a fourth pushbutton is provided to allow setting separate combinations for different stations. In a third embodiment, these functions are performed in a single-station controller by just two buttons and one LED.

  • Patent number: 6179221
    Abstract: A sprinkler for watering a fixed spray pattern includes a flow conduit having a nozzle coupled thereto. A filter screen is held in place beneath the nozzle. The filter screen engages against a poppet type valve member of a flow shut off valve to space the valve member away from a valve seat to permit water flow through the flow conduit when the filter screen and nozzle are in place. If the nozzle is removed, the filter screen can move far enough upwardly, or can itself also be removed, that the valve member closes to shut off flow through the flow conduit. The flow shut off valve is located at a fixed distance from a reference point in the top of the flow conduit to permit the same sized screen to open the valve regardless of the overall length of the flow conduit. A flush cap used initially on top of the flow conduit in place of the nozzle, i.e.

  • Patent number: 3934722
    Abstract: A tamperproof sterile needle package including a relatively rigid cartridge loosely supporting a hypodermic needle for aseptic removal. After the cartridge is opened, the needle is removed by tipping the cartridge body and spilling the loosely-supported needle onto a sterile surface. When sealed within the cartridge, the needle and its tip are fully protected against damage and contamination despite the loose fit between the parts. The cartridge includes a cover with an integral lever which is lifted to pry the cover free of the body, without contaminating either the needle or the mouth of the cartridge, when removal of the needle is desired.
