Abstract: The primary feature of the invention is a nozzle end which extends downward through a hole in the deck of a rotary mower and has a plurality of orifices, some of which are parallel to the deck and some are angled downward at an angle in a range of 1° to 45°. The orifices are radial from the axis of the nozzle end. The cleaning is done by supplying water to the orifices at household pressure while the mower is running at mowing speed. The nozzle having the nozzle end may be installed in the deck or manually held in place during use.

Abstract: Porous metallosilicate catalyst (e.g. Zeolite Beta) is active at low temperature for converting lower alkanol (e.g. methanol) and C.sub.4 -C.sub.7 tertiary alkenes to high octane ether product. Such catalytic reaction is especially useful in multizone catalytic reactor systems employing catstill rectification.

Abstract: A hydroturbine engine device having a plurality of notched discs mounted within a high pressure fluid chamber. A high pressure oil input is provided along the edges of said discs at one portion of the unit and an outlet for the spent oil is provided downstream thereof and adjacent thereto. The discs are keyed to a center driven shaft for connection to a work output. The turbine engine is connected to a high pressure oil pumping unit which supplies oil at high pressure to the input of said turbine engine. The turbine engine is also connected to an electrical alternator which in turn is connected to a storage battery through a voltage regulator system. The storage battery is used to at least partially drive the electric motor for the hydraulic oil pump. Thus, a portion of the energy output of the turbine engine is utilized in a feedback system for the oil pump to partially supply the source of hydraulic oil pressure for the turbine engine.
