A universal lighting system for use with a computer web camera including a digital computing device fitted with a web camera for capturing images of a subject for transmission over a worldwide communication network. A base clamping mechanism is affixed to the computing device. A light array is adjustably connected to the base clamping mechanism for illuminating the subject positioned before the web camera. A diffuser lens is flexibly connected to the base clamping mechanism and sealingly positioned over the web camera for diffusing received light for creating a clear image of the illuminated subject prior to transmission over the communication network.

An improved trickle irrigation unit includes a selector dial for controlling water flow through a plurality of outlet ports. The trickle unit comprises a valve housing having a water inlet port opening into one side of a pressure chamber, the other side of which is defined by a plurality of recessed flow patterns each leading to a respective one of the outlet ports. A resilient valve flap within the pressure chamber is hydraulically seated over the flow pattern and includes an array of flow passages alignable with selected flow patterns to permit water flow thereinto from the pressure chamber, with the flap deforming into the selected flow patterns for pressure-responsive flow control of water to the associated outlet ports. The valve flap is rotatably carried by the selector dial for movement to different set positions to alter the number of flow patterns aligned with flap flow passages thereby correspondingly altering the number of outlet ports in flow communication with the pressure chamber.

A retractable handle arrangement for a casket includes an elongate handle member, a rigid rod, and a stopper member. The elongate handle member has a length extending parallel to a side panel of the casket, and has a through-hole extending transverse to the length. The rigid rod extends through the through-hole of the handle member. The rigid rod has a first end and a second end, the first end having a head. The head has a diameter exceeding a diameter of at least a part of the through-hole. The rigid rod extends through a side panel opening such that the second end is disposed within an interior of the casket. The stopper member is fixedly supported on the rigid rod within the interior of the casket. The stopper member has a diameter that exceeds a diameter of at least a portion of the side panel opening.

In order to maintain the flue gas temperature from a steam generator up to the temperature required for a NO.sub.x catalytic reactor during low load operations, the flow of feedwater through the steam generator economizer is controlled to control the degree to which the flue gas is cooled as it passes over the economizer heat exchange surface. More specifically, an economizer bypass line is provided and the flow of feedwater during low load operations through the bypass line and the economizer is regulated to maintain a desired flue gas temperature to the catalytic reactor. As the flue gas temperature changes with load, the flow through the economizer and bypass line is modulated to maintain a proper temperature. At full or near full load, the bypass line is fully closed.

An up-spray deflector cup for use in an irrigation device of the type suspended from an overhead traveling irrigation system for discharging water from a downwardly directed nozzle in close proximity to the ground, the deflector cup being positioned centrally below the nozzle and serving to deflect water from the nozzle upwardly and radially outwardly as diametrically opposed from choped sprays. The deflector cup includes two concentric sets of deflecting surfaces for deflecting water from different size nozzles risible with the irrigation device.

A continuous tube emitter comprises an elongated flexible plastic tube with internal pressure-responsive flow control units to control the flow rate of irrigation water through outlet openings in the tube. The flexible plastic tube is formed from an elongated thin film web having one or more relatively thicker valve members on one side thereof defining a plurality of valve faces, wherein each valve face includes at least one shallow drip emission groove leading into a valve reservoir of wider cross section and communicating respectively with the outlet openings cut through the web. One longitudinal margin of the web is trimmed to form laterally projecting flaps at longitudinal positions generally corresponding with the valve faces. The web is then rolled upon itself about a longitudinal axis and longitudinally seamed to form the continuous tube emitter with the flaps each internally overlying the valve reservoir and a portion of the drip emission groove of a respective valve face to define one of the flow control units. In a preferred form, the flaps include structure for maintaining the flaps in close overlying relation with the valve faces. In use, water pressure within the tube forces the flaps into engagement with the aligned valve faces to restrict and control the rate of water flow through the outlet openings.
