Abstract: A rotational raking device for coupling to a rotating device that rotates the raking device about a longitudinal axis for raking leaves and other loose debris of a lawn. The rotational raking device includes an elongate shaft with opposite ends and a longitudinal axis that extends between the ends. A pair of elongate first brackets each have an axis that extends between opposite ends thereof. Each of the brackets is coupled to the shaft. Each of the brackets has a plurality of spikes that extend outwardly from it. Also disclosed is a rotating device for rotating the raking device.

Abstract: A portable foam generator system adaptable for use in any vehicle, land, sea or air. A plurality of separate trip zones are provided in the vehicle in the passenger compartment, engine compartment, fuel tank compartment and in other critical zones. When one of the vehicle trip zones receives a shock, there will be opened a ball valve to cause a mixing flow of water and foam which will exit through a foam line to the zone or zones provided. Each such zone includes a plurality of foam outlet nozzles selectively directed to provide maximum effective distribution of the foam. The particular foam used is a high expanding foam with non-flammable ingredients and including preferably a propanol solvent. The foam is such that it can be breathed and at the same time it protects passengers from flames. Dissipation of the foam after evacuation of the system is done without damage to articles or goods in the vehicle.
