Abstract: A trim ring is placed around an in-ground lawn sprinkler to discourage grass growth around it and to protect the sprinkler assembly by indicating its location. The sprinkler trim ring comprises two complementary plates, each having a notch or indents which, when assembled, forms a central aperture fitting around a sprinkler body. The overlapped plates are engaged and secured to each other by screws through slots in the upper plate and screwed into the lower plate. The slots permit sliding of the plates to increase or decrease the tightness on the sprinkler body. Grooves are provided on the bottom of both plates allowing breaking off portions to adapt to a larger sprinkler body and/or to installation site limitations.

Abstract: The present invention is an apparatus and method to reduce unwanted spraying of fluids from hose nozzles. In the preferred embodiment of the invention, a hole filled cover is attached over an open end of the nozzle of the hose. When the hose is in a position where unwanted spray is unlikely to take place the spray stream passes through the cover unaltered. If the nozzle moves to a position where unwanted spray is likely to take place, the cover deflects over the liquid stream causing it to be disbursed or scattered rather than sprayed over a long distance. The invention finds particular application in the prevention of spraying of water from the high pressure cleaning nozzle in swimming pool cleaners onto nearby objects or persons.

Abstract: A novel cutting nozzle assembly for a postmixed oxygen-fuel gas torch is disclosed. The nozzle assembly includes a cylindrical shroud which surrounds and extends away from the gas discharge orifices in the gas discharge end of the cutting nozzle. The cylindrical shroud has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of the preheat oxygen and the fuel gas to provide a hotter, more compact flame which produces a more parallel-sided cut through metal workpieces. The cutting tip therefore conserves metal as well as cutting gases. It also cuts faster than prior art postmixed cutting nozzles.

The present invention provides a device, which is easy to manipulate manually, and which enables the user to apply fertilizer to the seedling while simultaneously applying herbicide to the area around the seedling. The invention also provides a shroud for protecting the seedling while herbicide is being sprayed therearound.
