Abstract: Sprayer devices and related methods. The sprayer devices can be of a type that may be carried or worn on the back of a user. Each sprayer device has a tank, a spray outlet (e.g., a spray nozzle or spray wand) and either a manual or power pump. The sprayers may also incorporate one or more of the following: a) a brace member for deterring bending or deformation of a bottom bracket on the sprayer, b) a pump axle with redundant rotation-limiting stop members useable for either right-handed or left-handed operation, c) system for selective and/or controlled agitation or non-agitation of liquid within the sprayer tank and/or d) an information card holding niche with removable information card.

Abstract: System to prevent leaks of liquids in a manual sprayer—insecticides, herbicides, fungicides—comprised by a large storing tank in which a recipient is installed under pressure. A pumping assembly, which is manually activated, is connected to the inferior part of the container under pressure and to the lower part of the tank. The pumping assembly is comprised of an alternative piston to extract the liquid from the storing tank and to pressurize it inside the container under pressure. The pressurized liquid is applied using a hose and a regulating valve attached to the container under pressure.

Abstract: A truck having a tiltable platform or other cargo bed and its methods of use. In some embodiments, the rear suspension of the truck may be lowerable to lower the platform or bed while it undergoes tilting. In other embodiments the rear suspension need not be lowerable and the platform or bed may remain at constant height before, during and after tilting. An integrated hinge and inflatable air bags may be used to move the platform or bed between a horizontal position and a tilted position. One or more loading ramps are deployable to facilitate loading of different types of cargo or vehicles. The platform or bed may be equipped with holes in which pulleys for multiple angles can be placed. Shrouded air bags may be used to prevent unwanted movement or rattling of ramps or other structures.

Abstract: Improvements in an agricultural manual sprayer for preventing leakage of fluids such as insecticides, herbicides or fungicides that comprises tank with a large storage capacity into which a pressure vessel is installed. A manually activated pumping assembly is connected with the inferior section of the pressure vessel and also with the inferior section of the tank. The pumping assembly comprises a reciprocating piston pump for extracting the fluid from the storage tank and pressurizing it within the pressure vessel. The pressurized fluid is applied with a hose and a throttle valve attached to the pressure vessel. The assembly also comprises a double walled piston and barrier against leakage consisting of a ring with interior lips which seal it against the cylinder preventing the exit of fluid, forcing it to remain in the collection chamber until it is emptied with the downward movement of the piston, returning the liquid from the collection chamber to the storage tank through a return hose and internal ducts.
