An engine wash system with a collector includes a collection pan with a base angled toward a centerline and first and second panels rotatably connecting to first and second sides of the collection pan; a plurality of wheels connecting to the base; a first support connecting on a lower end to the collection pan and extending vertically upward from the collection pan; a first funnel connecting to the first support; and a first hose connecting the first funnel to the collection pan.

The present invention provides a method of suppressing larvae of barnacles in the settlement stage from settling on a substrate in water by irradiating light comprising the spectrum of 409 to 412 nm and a part of 400 to 460 nm to larvae of barnacles in the settlement stage in a direction from the substrate to the larvae of barnacles in the settlement stage.

The invention provides a method of operating a batch mixer for producing first and second numbers of mixtures from first and second numbers of batches of materials to be mixed in the batch mixer, the batch mixer comprising a mixing chamber, a mixing element disposed within the mixing chamber, the mixing element and the mixing chamber being configured for providing an identical flow of the materials to be mixed within the mixing chamber and around the mixing element regardless of in which of the first and second opposite directions the mixing element is rotated, and a motor assembly coupled to the mixing element for rotating the mixing element for mixing the first and second numbers of batches of materials to be mixed for producing the first and second numbers of mixtures. The method comprises the steps of energizing said motor assembly for rotating said mixing element in said first direction, for each one of the first number of batches of the materials to be mixed: loading the one of the first number of batches of materials to be mixed into the mixing chamber, mixing the one of the first number of batches of materials for producing one of the first number of mixtures, and removing the one of the first number of mixtures from the mixing chamber, energizing the motor assembly for rotating the mixing element in the second direction, and for each one of the second number of batches of the materials to be mixed loading the one of the second number of batches of materials to be mixed into the mixing chamber, mixing the one of the second number of batches of materials for producing one of the second number of mixtures, and removing the one of the second number of mixtures from the mixing chamber.

A mixing system includes a mixing machine and a device for collecting material of the mixture that remains adherent to the implement of the machine, at the end of a mixing step. The collecting device has a collecting surface that is associated to movement means designed to guide the surface in a first direction and a second direction, so that this can pass, as a result of the movement in both directions, from a first condition, where the surface extends at least prevalently in the first direction, to a second condition, where the surface extends at least prevalently in the second direction.

A personal protective field generator utilizes at least one pulse generator to generate one or more carrier signals, which are then modulated by a signal modulator unit and output through a field transmission unit in order to create a personal protective field around a user or other object through the “skin effect,” a byproduct of high frequency pulses at specific voltages. The personal protective field created through the skin effect can repel unwanted contact with the user such as insects, dust, chemical vapors or other environmental hazards.

A system includes a UV light source and an optical medium coupled to receive UV light from the UV light source. The optical medium is configured to emit UV light proximate to a surface from which biofouling is to be removed once the biofouling has adhered to the protected surface. A method corresponds to the system.
