A water stream stop valve for a sprinkler includes a tube body, an annular cover, multiple securing units, and a drainage body having a hole at the center thereof, is arranged above the tube body by multiple support plates. The water stream stop valve is incorporated in a pop-up sprinkler that includes a main body, an expansion pipe with a stop member arranged at top internal diameter thereof, a spray head, and the water stream stop valve arranged inside the expansion pipe and below the spray head. When the spray head falls off expansion pipe, the water stream stop valve will be pushed up to the top of the expansion pipe and stop at the stop member for avoiding the overflow of water while maintaining the spraying at the original area, and delivering a service indication stream.

Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes a low temperatures that do not deform the device. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

The invention relates to an apparatus 100, 200, 300, 700 and a method 400 for machining a workpiece 101 with a laser beam 102. The apparatus 100, 200, 300, 700 comprises a machining unit 103 configured to provide a pressurized fluid jet 104 onto the workpiece 101 and to couple the laser beam 102 through at least one optical element 105 into the fluid jet 104 towards the workpiece 101. Further, it comprises a sensing unit 107 arranged to receive a laser-induced electromagnetic radiation 106 propagating away from the workpiece 101 through the fluid jet 104 and through at least one optical element, and configured to convert the received radiation 106 into a signal 108. The apparatus 100, 200, 300, 700 also comprises a signal processing unit 109 configured determine a state of machining the workpiece 101 based on the signal 108.

A device for dispensing a fluid topical composition includes a reservoir storing the composition and dispensing a pressurized flow of the composition. The device also includes an accumulator having an expandable chamber in fluidly communication with the reservoir. The chamber is biased towards a deflated configuration so that, when filled with the composition the chamber expands against this bias applying pressure to the composition stored therein. The device includes a supply valve regulating the flow of the composition from the reservoir to the accumulator, and a pressure sensor. The device further includes a processing arrangement analyzing data from the sensor to determine whether pressure in the accumulator is above a predetermined threshold and controlling the supply valve to maintain the pressure within a desired pressure range. The device also includes a deposition arrangement dispensing the composition from the accumulator under control of the processing arrangement.
